Astrophile: A scorched world with snow black and smoky






















Astrophile is our weekly column on curious cosmic objects, from the solar system to the far reaches of the multiverse






















Object: Titanium oxide snow
Location: The hot-Jupiter planet HD 209458b












There is something magical about waking up to discover it has snowed during the night. But there's no powdery white blanket when it snows on exoplanet HD 209458b. Snow there is black, smoky and hot as hell – resembling a forest fire more than a winter wonderland. Put it this way: you won't be needing mittens.












HD 209458b belongs to a family called hot Jupiters, gas-giant planets that are constantly being roasted due to their closeness to their sun. By contrast, the gas giants in our immediate neighbourhood, including Jupiter, are frigid, lying at the solar system's far reaches.












HD 209458b is also noteworthy because it is tidally locked, so one side is permanently facing towards its star while the other is in perpetual night. On the face of it, these conditions wouldn't seem to invite snow: temperatures on the day side come close to 2000° C, while the night side is comparatively chilly at around 500° C.












Snow made of water is, of course, impossible on this scorched world, but the drastic temperature differential sets up atmospheric currents that swirl material from the day side to night and vice versa. That means that any substances with the right combination of properties might be gaseous on the day side and then condense into a solid on the night side, and fall as precipitation. Say hello to titanium oxide snow.











Stuck on the surface













Although oxides of titanium make up only a small component of a hot Jupiter's atmosphere, these compounds have the right properties to fall as snow. But there was a snag that could have put a stop to any blizzards. Older computer models of hot Jupiters suggested that titanium oxides condensing in the air on the night side would snow – and remain on the relatively cool surface forever. "Imagine on Earth if you had no mechanism to evaporate water, it would never rain," says Vivien Parmentier of the Côte d'Azur Observatory in Nice, France.












Now he and colleagues have created a more detailed 3D computer model that shows that the snow can become a gas again as it falls and the temperature and pressure increase. Strong updraughts can then blow the titanium oxides back to the upper atmosphere. "The gas can come back on the top layers and snow again and again," says Parmentier.












Snowfall on HD 209458b would be like none you've ever seen. Though titanium dioxide is white and shiny, for example, the snowflakes would also contain silica oxides from the atmosphere, making them black. Since the atmosphere is also dark, snowstorms on the planet would be a smoky affair, the opposite of the white-outs we get on Earth. "It would be like being in the middle of a forest fire," says Parmentier.











Although the team studied a particular hot Jupiter, their model should apply equally to other planets of this type, suggesting hot snow is a common occurrence. Parmentier says we may have already spotted snow clouds on another hot Jupiter, HD 189733b, as spectral analysis of the planet suggests the presence of microscopic particles in its atmosphereMovie Camera.













David Sing of the University of Exeter, UK, who helped identify such particles on HD 189733b, says the team's new model goes a long way to explaining how titanium oxides behave on hot Jupiters. "We're pretty used to water condensing on Earth; there it is titanium because the temperatures are so much hotter."












Hot, black snow – now that would be something to wake up to.

Singapore Conversation turns to animal welfare






SINGAPORE: A more inclusive society for animals or tougher rules for buying a pet were some suggestions animal lovers brought up at a dialogue on Saturday.

It was also the first time the Singapore Conversation - an initiative to get Singaporeans to come to a consensus on the kind of future they want - focused on animal welfare.

Saturday's event was jointly organised by the Agency for Animal Welfare, the Our SG Conversation Committee and the Singapore Kindness Movement.

Two working dogs - Esme and Joel - were present at the dialogue.

They were there to receive an inaugural Great Pet award given out by the Agency for Animal Welfare to pets which have served their owners in extraordinary ways.

Esme works as a guide dog for her visually impaired master, while Joel is a health service dog who can alert family members during a medical emergency at home.

Awareness of working dogs in Singapore remains low.

Hence animal lovers at the dialogue urged more shops and restaurants to welcome these dogs and their owners.

Their vision is an inclusive Singapore, for animals, too.

But pet owners need to do their part.

A keyword heard throughout the dialogue was "responsibility" - the responsibility of pet owners.

Abandonment cases in Singapore are unfortunately common. Hence some said the process of buying and owning a pet should be made tougher.

One of them is business owner Jill Hum, who said: "It's just far too easy for someone to buy a pet. It's not just buying candy or a teddy bear from the toy store. It's a live animal, you need to know how to take care of the pet. You need to know it's a lifelong commitment."

Others like Melanie Lee want an outright ban on live animals in pet stores.

"If pet shops can be legislated such that they can't have any live pets for sale, that would really help, because we have so many dogs out there - strays dogs, dogs up for adoption that do not have a home right now."

MP for Nee Soon GRC Associate Professor Faishal Ibrahim said the issue will require consultation with relevant stakeholders.

But the dialogue must go on.

"What we need to do is continue to develop and deepen this journey, so that ten years down the road, we will have a more gracious society," said the MP.

One way that can happen, participants said, is to inject the importance of animal welfare into the education system.

Super Bowl from the sidelines: Tech readiness is priority No. 1



View from main CBS control truck at the Superdome.



It's always a treat to watch the game coverage by the peerless NFL on CBS team, which is the very best in the business. And backing up our amazing group of analysts and experts in front of the camera is a trained crew of CBS Sports production and technical pros behind the scenes.

Their No. 1 priority is to deliver the perfect angle of every play, along with the sophisticated replays, zoom, and hyper-broadcast detail that TV viewers have grown to love. The production logistics and technical complexity associated with broadcasting the Super Bowl are astounding. This year, CBS Sports will have 62 cameras at the Superdome covering the game, along with dozens of replay devices. When you are able to capture virtually every detail of the action, the hard part becomes choosing the angles and replays wisely and making sure you don't interfere with the broadcast.



In the mix will be some 4K cameras, which allow for stunning zooming capabilities, as well as the CBS sky cam, which glides over the field on a cable, capturing all. Orchestrating and syncing all the associated gear -- including switchers, audio consoles, graphics gear packages, servers HD cam decks, and a whole lot of cable -- is a massive undertaking. Beyonce is not the only one rehearsing ahead of Sunday -- there have been production rehearsals every day this week to get ready.


I'm in awe of the process and all of my colleagues at CBS Sports who make the magic happen. The final countdown has begun, so follow me on Twitter at and stay tuned!

Pictures We Love: Best of January

Photograph by Dieu Nalio Chery, AP

The magnitude 7 earthquake that struck near Port au Prince, Haiti, in January 2010 so devastated the country that recovery efforts are still ongoing.

Professional dancer Georges Exantus, one of the many casualties of that day, was trapped in his flattened apartment for three days, according to news reports. After friends dug him out, doctors amputated his right leg below the knee. With the help of a prosthetic leg, Exantus is able to dance again. (Read about his comeback.)

Why We Love It

"This is an intimate photo, taken in the subject's most personal space as he lies asleep and vulnerable, perhaps unaware of the photographer. The dancer's prosthetic leg lies in the foreground as an unavoidable reminder of the hardships he faced in the 2010 earthquake. This image makes me want to hear more of Georges' story."—Ben Fitch, associate photo editor

"This image uses aesthetics and the beauty of suggestion to tell a story. We are not given all the details in the image, but it is enough to make us question and wonder."—Janna Dotschkal, associate photo editor

Gov's Handling of Sandusky Case Under Investigation













The newly-elected attorney general of Pennsylvania is going after the state's governor, Tom Corbett, who was attorney general when child sex allegations against Penn State coach Jerry Sandusky were first brought forward.


Kathleen Kane, a Democrat who was sworn in as attorney general on Jan. 15, said that she will name a special prosecutor in the coming days to investigate Corbett's handling of the Sandusky case. Corbett is a Republican.


The investigation will look specifically at why it took the attorney general's office three years to bring criminal charges against Sandusky while he continued to have access to children.


"Attorney General Kane will appoint a special prosecutor to lead the office's internal investigation into how the Sandusky child abuse investigation was handled by the Office of the Attorney General," Kane's office said in a statement released today.


Corbett's attorney general's office was first notified of the allegations against Sandusky in 2008 when a high school student told his mother and school that Sandusky had molested him. The local district attorney passed the allegation on to the attorney general, then Corbett. Corbett convened a grand jury.

It wasn't until 2011 that sex abuse charges were filed against Sandusky while Corbett had since become governor. Sandusky was convicted on 45 counts of sex abuse in June 2012.


The charges sent shockwaves throughout Pennsylvania, as Penn State's president, two top officials, and legendary coach Joe Paterno all lost their jobs over the scandal.


"Why did it take 33 months to get Sandusky off the streets? Was the use of a grand jury the right decision? Why were there so few resources dedicated to the investigation? Were the best practices implemented?" the statement from Kane's office read.


"At the end of this investigation, we will know the answers to these questions and be able to tell the people of Pennsylvania the facts and give them answers that they deserve," the statement said.


Describing an interview Kane gave the New York Times, the Times said Kane suggested that Corbett did not want to upset voters or donors in the Penn State community before his gubernatorial run in 2009.


Corbett has denied those suggestions. His office did not immediately return calls for comment.


Kane's office preemptively fought back against the idea that the investigation is politically motivated. Kane, a Democrat, defeated the incumbent attorney general, Linda Kelly, a Republican in November 2011. Corbett is a Republican.


"The speculation that this is about politics is insane," a staff member in Kane's office told ABC News today. "You go anywhere in Pennsylvania and anywhere across the country and you'll find individuals asking, 'why did it take three years? Why was there a grand jury? Why make these kids talk to 30 different people about what happened?"

Archimedes's favourite insight printed in 3D









































See more in our gallery: "3D printer reveals mathematical beauty – and surprise"












ARCHIMEDES was at the cutting-edge of Ancient Greek technology but he might have increased his ability to engage with ordinary folk had he access to a 3D printer.












One of the polymath's favourite proofs was showing mathematically that a sphere that fits exactly inside a cylinder fills two thirds of its volume. A representation of this was displayed on his tomb.












Now, to mark the 2300th anniversary of his birth, Elizabeth Slavkovsky and Oliver Knill of Harvard University have used a 3D printer to create an object of the precise dimensions needed to demonstrate the insight visually.












They printed a slightly different version of the proof - a hollow hemisphere supported above a cylinder which contains a cone that takes up one third of the cylinder's volume (pictured below). Fill the hemisphere with water and it drains into the cylinder, filling it exactly to the brim. Using a hemisphere means you can see the water drain, making it easy to grasp what Archimedes proved (arxiv.org/abs/1301.5027).












The pair reckon that 3D printers - which make it easy to create objects based on equations - could transform mathematics education. Slavkovsky has helped students print personalised mathematical objects. "It gave them a tangible thing to consider," she says.

US says Australia "critical pillar" in Asia pivot






TOKYO: Australia is a "critical pillar" in the US pivot to Asia and the rebalancing of its military strategy, the region's most senior American commander told reporters on Friday.

Chief of US Pacific Command (PACOM) Samuel Locklear speaking in a teleconference from Hawaii, said the key US ally was vital in the world order that is emerging for the 21st Century.

Locklear said the challenges the US faced included climate change, maritime security, disaster relief and cyber security.

"All those things I view from the PACOM headquarters here, Australia is a critical pillar of the strategy we have here," Locklear said.

"When... I go down to Canberra and I sit and I look at the world map from Australia being in the centre of it, I get a very different view than I get from Hawaii or from Washington DC.

"And I start to have a sense of the things of the security environment that concerned people of Australia as well as people in Indonesia, in India and other countries."

Locklear said seen from this perspective, the Indian Ocean is a vital strategic region that cannot be thought of separately from the Asia-Pacific.

"When we look at our relationship with Australia, number one, a very good close ally, historically has been alongside with the US many times in the past, and I think will hopefully continue in the future," he said.

The US military is to station a powerful radar and a space telescope in Australia as part of a refocusing of priorities, the two countries announced in November.

The two sides also conferred on increasing the number of US Marines deploying to Darwin.

US Defence Secretary Leon Panetta described it as "major leap forward in bilateral space cooperation and an important new frontier in the United States' rebalance to the Asia-Pacific region".

In his first term as US President, Barack Obama said he wanted to refocus foreign policy on Asia, in a move that has been much trailed as a "pivot".

Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos













Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.


The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."


Arias' attorneys introduced as evidence photos that Alexander took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.


Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.


Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.


"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.


"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.


Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.


Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."


"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.


Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.


In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.


"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"


"She would not be ready to be baptized in that case," Freeman said.


"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.


"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."


Freeman said that Alexander never confessed to having a sexual relationship with Arias.


Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.


The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.

Trend-setting chimp teaches friend to use a straw



Sandrine Ceurstemont, editor, New Scientist TV






If your friend has a more efficient way of getting food, it makes sense to copy them. Now an experiment is showing for the first time that chimps also come to the same conclusion.



Captured by Shinya Yamamoto from Kyoto University in Japan and colleagues, this video shows how a chimp improves its use of a straw after observing a more proficient companion. At first, it uses the tool almost like an eye-dropper, dipping it in a box to sop up juice. But after it watches its friend drink faster by sucking on the straw, it learns to adopt this new approach. According to the team, which studied nine chimps, once an ape switched to straw-sucking, it never went back to the less efficient dipping technique.







Although it's well known that chimps learn socially, it's the first time they've been shown to improve the way they use a tool, which is a comparatively sophisticated ability. It requires a chimp to differentiate between two techniques involving the same instrument to achieve an identical goal.



The experiment shows that these apes have the mental capacity to evolve their cultural learning. "The limitations might be due to ecological, social and motivational factors rather than cognitive abilities," write the researchers.

Malaysian conglomerate confident of turning loss-making Lotus around






KUALA LUMPUR: Malaysian conglomerate DRB HICOM is confident it can turn around loss-making sports car manufacturer Lotus in two to three years.

The company recently dispelled rumours it's selling off the British motoring legend by setting up its first regional showroom in Asia.

Spanning over 10,000 square metres, the Lotus flagship showroom located along Kuala Lumpur's Penchala Link is a haven for its fans.

On display are Lotus' latest sports car models, including its Formula One race car.

It also features the widest selection of Lotus accessories and merchandise, as well as a service centre, a club house, and a gallery documenting the iconic British brand's 60-year history.

The message is clear from its parent company DRB HICOM that Lotus is not for sale.

In fact, it has invested US$2.5 million to set up a regional flagship showroom and service centre, and set ambitious sales targets, as it officially launched two new models.

They are the Exige S and the Elise S, with a price range of between US$110,000 and US$150,000.

There's also the Evora, which offers a manual and an auto version.

Lotus, which is owned by Malaysia's national car manufacturer Proton, aims to sell up to 3,500 of these cars this year, especially in North America, China, Japan and Middle East markets.

It has so far received 600 orders.

The Chairman of Lotus Group International is a car enthusiast, and he is determined to nurse the heavily-indebted legendary sports car manufacturer back to health.

Mr Mohd Khamil Jamil, Chairman of Lotus Group International, said: "No doubt that the damage or whatever the situation at Lotus was quite severe, but nothing is short of repair. We reckon that with the expertise we have at Lotus and the expertise that we have in Proton, we can work together and synergize and make Lotus into a profitable company which is commercially driven.

"Unfortunately, during the 15 or 16 years or so that Proton had gotten Lotus within their wings, they have not explored as much as possible to make use of whatever benefits they could derive from Lotus."

On how much time needed to turn around the company and to stop Lotus from bleeding, Mr Mohd Khamil said certain culture and practices entrenched in Lotus needs to be changed.

"Right now, I think we have reduced quite substantially in terms of overheads alone. We have reduced by more than one million pounds a month. And I believe with the astute management by the team now, we can reduce it even further. At the end of the day, I reckon that we may take about two to three years for us to ensure that Lotus can be sustainable," he said.

With a new management at the helm, Lotus aims to slash its costs by 25 per cent, and rev up its marketing campaigns to improve its visibility and sales worldwide.

Tumblr avoids porn label and adds mature rating to iOS app



Tumblr's iPhone app.



(Credit:
Tumblr)


Tumblr looks to be trying to avoid the porn-war that recently harangued the 500px photo app and Twitter's Vine app.

The microblogging company threw up a 17-and-over age warning for its iOS app for all new users and any people updating their app to the 3.2.4 version, which was released today.

"You must be at least 17 years old to download this app," Tumblr writes in its description of the app in the iTunes App Store, because it contains "Frequent/Intense Sexual Content or Nudity."

The app's upgrade says only that it will carry out "small bug fixes." However, when users click on the 3.2.4 version, they're forced to confirm they are over the age of 17. "Tumblr contains age-restricted material," the app says when upgrading. "Tap OK to confirm that you are 17 or over. Your content will then begin downloading immediately."

It's unclear exactly why Tumblr changed its app to contain a mature rating. But it's no secret that certain blogs on the site contain "sexual content" and "nudity." In an interview last June, Tumblr founder David Karp noted that 2 percent to 4 percent of the traffic on Tumblr is porn-related.

Tumblr's 17+ rating comes as 500px and Vine have been scrutinized for making porn easily accessible. When Twitter released the Vine app last week, many users quickly found a handful of videos featuring male exhibitionism and other activity. Apple quickly stopped promoting Vine in its App Store.

500px had an even more severe reprimand. After complaints of the app containing pornographic images and material, Apple pulled it from
iTunes. Now that 500px has added warnings and a 17+ rating, Apple allowed it back into the App Store.

Maybe Tumblr is acting preemptively with its new 17+ rating. CNET contacted Tumblr for comment. We'll update the story when we get more information.

New Theory on How Homing Pigeons Find Home

Jane J. Lee


Homing pigeons (Columba livia) have been prized for their navigational abilities for thousands of years. They've served as messengers during war, as a means of long-distance communication, and as prized athletes in international races.

But there are places around the world that seem to confuse these birds—areas where they repeatedly vanish in the wrong direction or scatter on random headings rather than fly straight home, said Jon Hagstrum, a geophysicist who authored a study that may help researchers understand how homing pigeons navigate.

Hagstrum's paper, published online Wednesday in the Journal of Experimental Biology, proposes an intriguing theory for homing pigeon disorientation—that the birds are following ultralow frequency sounds back towards their lofts and that disruptions in their ability to "hear" home is what screws them up.

Called infrasound, these sound waves propagate at frequencies well below the range audible to people, but pigeons can pick them up, said Hagstrum, who works at the U.S. Geological Survey in Menlo Park, California.

"They're using sound to image the terrain [surrounding] their loft," he said. "It's like us visually recognizing our house using our eyes."

Homeward Bound?

For years, scientists have struggled to explain carrier pigeons' directional challenges in certain areas, known as release-site biases.

This "map" issue, or a pigeon's ability to tell where it is in relation to where it wants to go, is different from the bird's compass system, which tells it which direction it's headed in. (Learn about how other animals navigate.)

"We know a lot about pigeon compass systems, but what has been controversial, even to this day, has been their map [system]," said Cordula Mora, an animal behavior researcher at Bowling Green State University in Ohio who was not involved in the study.

Until now, the two main theories say that pigeons rely either on their sense of smell to find their way home or that they follow the Earth's magnetic field lines, she said.

If something screwed up their sense of smell or their ability to follow those fields, the thinking has been, that could explain why pigeons got lost in certain areas.

But neither explanation made sense to Hagstrum, a geologist who grew interested in pigeons after attending an undergraduate lecture by Cornell biologist William Keeton. Keeton, who studied homing pigeons' navigation abilities, described some release-site biases in his pigeons and Hagstrum was hooked.

"I was just stunned and amazed and fascinated," said Hagstrum. "I understand we don't get dark matter or quantum mechanics, but bird [navigation]?"

So Hagstrum decided to look at Keeton's pigeon release data from three sites in upstate New York. At Castor Hill and Jersey Hill, the birds would repeatedly fly in the wrong direction or head off randomly when trying to return to their loft at Cornell University, even though they had no problems at other locations. At a third site near the town of Weedsport, young pigeons would head off in a different direction from older birds.

There were also certain days when the Cornell pigeons could find their way back home from these areas without any problems.

At the same time, homing pigeons from other lofts released at Castor Hill, Jersey Hill, and near Weedsport, would fly home just fine.

Sound Shadows

Hagstrum knew that homing pigeons could hear sounds as low as 0.05 hertz, low enough to pick up infrasounds that were down around 0.1 or 0.2 hertz. So he decided to map out what these low-frequency sound waves would have looked like on an average day, and on the days when the pigeons could home correctly from Jersey Hill.

He found that due to atmospheric conditions and local terrain, Jersey Hill normally sits in a sound shadow in relation to the Cornell loft. Little to none of the infrasounds from the area around the loft reached Jersey Hill except on one day when changing wind patterns and temperature inversions permitted.

That happened to match a day when the Cornell pigeons had no problem returning home.

"I could see how the topography was affecting the sound and how the weather was affecting the sound [transmission]," Hagstrum said. "It started to explain all these mysteries."

The terrain between the loft and Jersey Hill, combined with normal atmospheric conditions, bounced infrasounds up and over these areas.

Some infrasound would still reach Castor Hill, but due to nearby hills and valleys, the sound waves approached from the west and southwest, even though the Cornell loft is situated south-southwest of Castor Hill.

Records show that younger, inexperienced pigeons released at Castor Hill would sometimes fly west while older birds headed southwest, presumably following infrasounds from their loft.

Hagstrum's model found that infrasound normally arrived at the Weedsport site from the south. But one day of abnormal weather conditions, combined with a local river valley, resulted in infrasound that arrived at Weedsport from the Cornell loft from the southeast.

Multiple Maps

"What [Hagstrum] has found for those areas are a possible explanation for the [pigeon] behavior at these sites," said Bowling Green State's Mora. But she cautions against extrapolating these results to all homing pigeons.

Some of Mora's work supports the theory that homing pigeons use magnetic field lines to find their way home.

What homing pigeons are using as their map probably depends on where they're raised, she said. "In some places it may be infrasound, and in other places [a sense of smell] may be the way to go."

Hagstrum's next steps are to figure out how large an area the pigeons are listening to. He's also talking to the Navy and Air Force, who are interested in his work. "Right now we use GPS to navigate," he said. But if those satellites were compromised, "we'd be out of luck." Pigeons navigate from point to point without any problems, he said.

No Device Eliminates Concussion Risk, Experts Say













As the long-term consequences of concussions become clearer, a cottage industry has popped up to sell athletes and worried parents products designed to mitigate risks of concussions that even helmets cannot prevent.


Despite the bold claims of some companies, however, many experts say the Holy Grail in contact sports -- a device that prevents concussions -- simply does not exist. Indeed, experts say, there is no proof that any current device significantly reduces the risk of concussions beyond the protections already provided by helmets.


"Nightline" found several products for sale online that aim to reduce the risk of concussions or even alert parents and coaches when a kid has supposedly taken a concussion-level hit. The claims the manufacturers make are often breathtakingly reassuring.


Concern about the risk of concussion is mounting at every level of the gridiron from the NFL to colleges and even high schools. Concussions are the most common injury among high school football players.


Jennifer Branin, whose son Tyler Branin is one of the stars of the Woodbridge Warriors high school football team in Irvine, Calif., said "it was scary" the first time he had a concussion.


"He had lost his balance on the field," she said. "He got up and tried to continue, but couldn't keep his balance."








Junior Seau Had Brain Disease, Researchers Say Watch Video









She said the effects of the concussion lingered, causing Tyler to miss a week of school and football practice. Even months later, he complained of difficulty concentrating in class.


Parents such as Jennifer Branin, who is president of the team's booster club, and her husband, Andy Branin, a former college football player himself, were looking for a way to support their son's desire to play football while also keeping him safe.


"He wants to play and, as a mom, you may want to put bubble-wrap around them and protect them forever, but that's not going to happen," she said.


So Jennifer Branin decided to do something. She raised money to buy the team helmet inserts by Unequal Technologies for added protection.


Unequal Technologies, one of the highest profile players in this new market, described its product explicitly on the box as "Concussion Reduction Technology," or "CRT." It is a strip of composite material including bullet-proof Kevlar that is designed to stick inside the helmet as a liner to the existing helmet pads.


Unequal Technologies uses its material in products ranging from padded sleeves to shin guards. The company counts NFL players and X-Games athletes among its fans.


On board as paid spokesmen are Philadelphia Eagles quarterback Michael Vick and James Harrison, a linebacker for the Pittsburgh Steelers. Harrison is one of the hardest-hitting guys in the NFL and said he uses Unequal Technology's liners in his helmet.


"I don't know what it's made of but it works," Harrison says in one of Unequal's promotional videos. "I really don't feel like I'm taking a risk."


Vick wasn't wearing the CRT product when he suffered a season-ending concussion in November, but he has since promised that he will be wearing it when he returns to the field next season.


Rob Vito, founder and CEO of the Kennett Square, Pa.-based company, said he worked with scientists to create a military-grade composite material that can help protect athletes from all kinds of injuries from head to toe.

MINDEF signs contract with ST Engineering to construct naval vessels






SINGAPORE: Singapore's Defence Ministry (MINDEF) has signed a contract with Singapore Technologies Engineering Ltd for the design and construction of eight new naval vessels.

MINDEF said it will replace the existing Fearless-class Patrol Vessels (PVs) in the Republic of Singapore Navy (RSN).

The Patrol Vessels will reach the end of their operational lifespan in 2020 after being in service for more than 20 years.

MINDEF added that the new vessels will be equipped with enhanced combat systems and integrated communications suites that will help the Navy to undertake a wide range of maritime security operations.

This will enable it to more effectively, carry out its mission of safeguarding Singapore's vital sea lines of communication.

The first vessel is expected to be delivered in 2016 and all eight vessels will be fully operational by 2020.

Michael Dell to use personal funds to seek majority control -- report



Dell founder and Chief Executive Michael Dell.



(Credit:
James Martin/CNET)

Just weeks after reports surfaced that Dell was looking to go private, the company's founder appears willing to put his personal funds where his mouth is.


Michael Dell may kick in equity financing of $500 million to $1 billion combined with his 15.7 percent stake in the company to seek majority control of the company, according to Bloomberg. That would push his ownership stake past 50 percent.

With the investment, Dell would be contributing more than half of the total $8 billion to $9 billion equity check. The remainder of the takeover would be financed by debt and "possibly some of the $11 billion of cash Dell reported it had as of September 30," according to Bloomberg.


This follows on the heels of reports that Microsoft may contribute $1 billion to $3 billion and was in talks with Silver Lake Partners to help take Dell private.


However, the WSJ today reported that Microsoft's role in the new company has been a sticking point in negotiations. Though the deal is still expected to stay on track, Microsoft wants to have a say in some of Dell's operations rather than just being a source of funding, according to the WSJ's sources.


Dell, a one-time leading PC maker, has hit hard times of late. The company's stock has continued to lose value as it defends itself against rivals, and despite the many acquisitions it's made over the past several years, there are concerns about how fast those businesses are taking off. Some industry watchers are hoping that going private could give it the reboot that it needs.

Timbuktu’s vulnerable manuscripts are city’s "gold"


French and Malian troops surrounded Timbuktu on Monday and began combing the labyrinthine city for Islamist fighters. Witnesses, however, said the Islamists, who claim an affiliation to al Qaeda and had imposed a Taliban-style rule in the northern Malian city over the last ten months, slipped into the desert a few days earlier.

But before fleeing, the militants reportedly set fire to several buildings and many rare manuscripts. There are conflicting reports as to how many manuscripts were actually destroyed. (Video: Roots of the Mali Crisis.)

On Monday, Sky News posted an interview with a man identifying himself as an employee of the Ahmed Baba Institute, a government-run repository for rare books and manuscripts, the oldest of which date back to the city's founding in the 12th century. The man said some 3,000 of the institute's 20,000 manuscripts had been destroyed or looted by the Islamists.

Video showed what appeared to be a large pile of charred manuscripts and the special boxes made to preserve them in front of one of the institute's buildings.

However, a member of the University of Cape Town Timbuktu Manuscript Project told eNews Channel Africa on Tuesday that he had spoken with the director of the Ahmed Baba Institute, Mahmoud Zouber, who said that nearly all of its manuscripts had been removed from the buildings and taken to secure locations months earlier. (Read "The Telltale Scribes of Timbuktu" in National Geographic magazine.)

A Written Legacy

The written word is deeply rooted in Timbuktu's rich history. The city emerged as a wealthy center of trade, Islam, and learning during the 13th century, attracting a number of Sufi religious scholars. They in turn took on students, forming schools affiliated with's Timbuktu's three main mosques.

The scholars imported parchment and vellum manuscripts via the caravan system that connected northern Africa with the Mediterranean and Arabia. Wealthy families had the documents copied and illuminated by local scribes, building extensive libraries containing works of religion, art, mathematics, medicine, astronomy, history, geography, and culture.

"The manuscripts are the city's real gold," said Mohammed Aghali, a tour guide from Timbuktu. "The manuscripts, our mosques, and our history—these are our treasures. Without them, what is Timbuktu?"

This isn't the first time that an occupying army has threatened Timbuktu's cultural heritage. The Moroccan army invaded the city in 1591 to take control of the gold trade. In the process of securing the city, they killed or deported most of Timbuktu's scholars, including the city's most famous teacher, Ahmed Baba al Massufi, who was held in exile in Marrakesh for many years and forced to teach in a pasha's court. He finally returned to Timbuktu in 1611, and it is for him that the Ahmed Baba Institute was named.

Hiding the Texts

In addition to the Ahmed Baba Institute, Timbuktu is home to more than 60 private libraries, some with collections containing several thousand manuscripts and others with only a precious handful. (Read about the fall of Timbuktu.)

Sidi Ahmed, a reporter based in Timbuktu who recently fled to the Malian capital Bamako, said Monday that nearly all the libraries, including the world-renowned Mamma Haidara and the Fondo Kati libraries, had secreted their collections before the Islamist forces had taken the city.

"The people here have long memories," he said. "They are used to hiding their manuscripts. They go into the desert and bury them until it is safe."

Though it appears most of the manuscripts are safe, the Islamists' occupation took a heavy toll on Timbuktu.

Women were flogged for not covering their hair or wearing bright colors. Girls were forbidden from attending school, and boys were recruited into the fighters' ranks.

Music was banned. Local imams who dared speak out against the occupiers were barred from speaking in their mosques. In a move reminiscent of the Taliban's destruction of Afghanistan's famous Bamiyan Buddha sculptures, Islamist fighters bulldozed 14 ancient mud-brick mausoleums and cemeteries that held the remains of revered Sufi saints.

A spokesman for the Islamists said it was "un-Islamic" for locals to "worship idols."

Clinton Talks 2016, Stands by Benghazi Testimony













In her final television interview as Secretary of State, Hillary Clinton told ABC's Cynthia McFadden that she is "flattered and honored" at the intense interest in whether she might run for president in 2016.


But Clinton maintained that right now she's "not focused" on a presidential campaign; instead she said she wants to return to a "normal" life when she steps down from office on Friday.


Watch Cynthia McFadden's full interview with Secretary of State Hillary Clinton on "Nightline" tonight at 12:35 a.m. ET


Clinton's first order of business, she said, will be sleep.


"I hope I get to sleep in," she told McFadden with a laugh. "It will be the first time in many years. I have no office to go to, no schedule to keep, no work to do. That will probably last a few days then I will be up and going with my new projects," she said.


"I have been working or attending school full-time since I was 13. This is going to be new for me. I don't know how I'm going to react to it, to be honest."

Clinton has had no trouble articulating her reaction to what has arguably been the darkest chapter of her tenure as Secretary of State: the Sept. 11 attack on the U.S. consulate in Benghazi, Libya, in which four Americans, including Ambassador Chris Stevens, were killed.








Hillary's Next Chapter: On Family and Future Watch Video









Secretary Clinton had a heated exchange with Republican Senator Ron Johnson during her five hours of testimony before Congress about the attack last week. Johnson accused the administration of misleading the American people about the cause of the attack, when UN Ambassador Susan Rice, on Sunday political talk shows, blamed it on protesters.


Clinton snapped back at Johnson, "Four Americans are dead. What difference does it make?" For that, she has been sharply criticized by some conservatives.


Clinton said she "absolutely" stands by her response to Johnson, maintaining that the administration has been transparent with the information it knew, when it was available. Clinton said partisan politics have no place in a response to a terrorist attack against Americans.


"I believe that we should in public life, whether you're in the administration or the Congress, de-politicize crisis and work together to figure out what happened, what we can do to prevent it and then put into place both the institutional changes and the budgetary changes that are necessary, " she said.


"When someone tries to put into a partisan lens, when they focus not on the fact that we have such a terrible event happening with four dead Americans but instead what did somebody say on a Sunday morning talk show? That to me is not in keeping with the seriousness of the issue and the obligation we all have as public servants"


FULL TRANSCRIPT: Sec. of State Hillary Clinton's "Nightline" Interview


Asked about her health, Clinton said her recent illness, concussion and blood clot were all a surprise.


"When I got sick and fainted and hit my head I was so surprised, and I thought I would just get up and go to work. And thankfully I had very good medical care and doctors who said, 'No we'd better do an MRI, we'd better do this, we'd better do that,'" she said, calling herself "lucky."


"I know now how split second beset by a virus and dehydrated, what it can do to you."


Though she confirmed she is wearing special glasses to help with double vision, a lingering issue following her illness, Clinton said that she expects to be fully recovered and operating at "full speed" soon.


The Secretary told McFadden that if she does decide to run, she would have "no problem" making her health records public.


"Of course, that goes with the territory," she said.

Iran launches monkey into space



Lisa Grossman, physical sciences reporter
Last summer, the Iranian Space Agency announced their plan to send a monkey into space - and now they've apparently done it.

According to Iranian state-run television, a press release on the space agency's website, and photos of the event, Iran sent a live rhesus monkey into sub-orbital space aboard a small rocket called Pishgam, or Pioneer. There's even a video posted on YouTube that appears to be of the launch (though New Scientist could not confirm its authenticity).

The report has not been confirmed independently, however, and the US air force's North American Aerospace Defense Command (NORAD) has not reported seeing any missile launches from Iran.

But independent observers say the launch looks legitimate.

"Really, I see no reason not to take their word for it," says Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who also keeps a log of space launches. He says he's convinced by the photos and discussions he's had with several knowledgeable source in online forums.

In photos released on the Iranian Space Agency's website, the rocket looks like the same kind the agency has launched before, but with a larger nose cone designed to fit a small chamber that can support life. Images also showed a live rhesus monkey strapped to a small seat.

The reports say the rocket went straight up 120 kilometres, which McDowell says qualifies as outer space, but not high enough to reach orbit, and came back down with a parachute.

It's unclear exactly when the launch took place. The press release says that the launch happened on the birthday of Mohammed the Prophet, which is celebrated by Shiites on 29 January, but was celebrated last week elsewhere in the world.

Some countries worry that Iranian rockets capable of carrying animals or people could also carry weapons. Iran has denied any military intention.

"This is not a scary thing because this is not a big new rocket that could hit America or anything like that," McDowell says. "There's nothing military to this. It's purely for propaganda. Nevertheless, it advances their science and their technology by being able to do it."

Iran says the launch is a first step towards sending humans into space, which they intend to do in the next 5 to 8 years. To do that, McDowell says, they'll need to build a larger rocket. The country currently has a vehicle called Safir that has successfully put satellites in orbit, and is developing a more powerful launcher called Simorgh.

The next step will probably be to either launch Safir to carry a human to sub-orbital space, or an unmanned Simorgh flight into orbit to make sure mission controllers can return it to the ground safely.

"They don't want to repeat what the Soviets did" in 1957, McDowell says, "which is put a living being in orbit before you figure out how to get it back."

Forget Episode VII, watch 'JJ Abrams Star Wars - The Musical'




Are you a late-model "Star Trek" fan with issues about your guy J.J. Abrams jumping ship in order to direct the next "Star Wars" film? Or maybe a "Star Wars" devotee filled with dread at having your favorite franchise be under the control of someone who's directed two "Star Trek" films?


If so, there's a musical for you. "JJ Abrams Star Wars -- The Musical," to be precise.


Picture Darth Vader and Abrams singing at each other on a pier. Picture Vader shaming Abrams -- well, a very poor look-alike at least -- with a line like, "So you think // you can walk right in // You who joined with the other side // You now betray every 'Star Trek' fan // You have crushed their pride." And then Abrams' rejoinder, "It is true // That I have jumped ship // I was always a Star (Trek) Wars guy // I cannot pass on this perfect chance // Let's see eye to eye."


This is YouTube silliness at its best. It's topical, it's funny (sort of), and it's camp of the highest order. What's not to love?

Abrams, of course, was recently named the director of the "Star Wars Episode VII" after already directing 2009's "Star Trek," and the forthcoming "Star Trek Into Darkness."


Some, of course, wonder whether someone with such a "Star Trek" pedigree can switch sides.


But as our musical's fictional Abrams notes to the incredulous Vader, he will return the "Star Wars" franchise to its glory days, starting with what every real fan's obvious first step: killing off Jar Jar.

Space Pictures This Week: Martian Gas, Cloud Trails

Image courtesy SDO/NASA

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.

US Mom Missing in Turkey Took Side Trips













Sarai Sierra, the New York mother who disappeared in Turkey while on a solo trip, took several side excursions out of the country, but stayed in contact with her family the entire time, a family friend told ABC News.


Turkish media reported today that police were trying to establish why Sierra visited Amsterdam and Munich. Police were also trying to establish the identity of a man Sierra, 33, was chatting with on the Internet, according to local media.


Rachel Norman, a family friend, said the man was a group tour guide from the Netherlands and said Sierra stayed in regular touch with her family in New York.


Steven Sierra, Sarai's husband, and David Jimenez, her brother, arrived in Istanbul today to aid in the search.


The men have been in contact with officials from the U.S. consulate in the country and plan to meet with them as soon as they open on Tuesday, Norman said.


After that, she said Sierra and Jimenez would meet with Turkish officials to discuss plans and search efforts.

Sarai Sierra was supposed to fly back to the United States on Jan. 22, but she never showed up for her flight home.


Her two boys, ages 11 and 9, have not been told their mother is missing.


Sierra, an avid photographer, left New York on Jan. 7. It was her first overseas trip, and she decided to go ahead after a friend had to cancel, her family said.


"It was her first time outside of the United States, and every day while she was there she pretty much kept in contact with us, letting us know what she was up to, where she was going, whether it be through texting or whether it be through video chat, she was touching base with us," Steven Sierra told ABC News before he departed for Istanbul.


But when it came time to pick her up from Newark Liberty International Airport in New Jersey, Sierra wasn't on board her scheduled flight.


Steven Sierra called United Airlines and was told his wife had never boarded the flight home.


Further investigation revealed she had left her passport, clothes, phone chargers and medical cards in her room at a hostel in Beyoglu, Turkey, he said.


The family is suspicious and said it is completely out of character for the happily married mother, who met her husband in church youth group, to disappear.


The U.S. Embassy in Turkey and the Turkish National Police are involved in the investigation, WABC-TV reported.


"They've been keeping us posted, from my understanding they've been looking into hospitals and sending out word to police stations over there," Steven Sierra said. "Maybe she's, you know, locked up, so they are doing what they can."

Anger over delay in govt's decision on new Indian state






INDIA: Protests are simmering on the streets of the Andhra Pradesh state capital, Hyderabad, in India. Anger is growing as the federal government deferred a decision on the formation of a new state.

In December, the central government had said it would decide within a month, on a proposal to form a separate Telangana state out of Andhra Pradesh.

It now says more time is needed for consultations on the issue.

Congress leader Nabi Azad said: "It's not the time. But we will invite them, as I said Chief Minister and PCC President, and senior leaders of Andhra Pradesh as early as possible."

Pro-Telangana activists launched a 36-hour protest on Sunday to mount pressure on the government to concede to their demand.

A university in the state capital saw violent protests and police used tear gas to disperse the students demanding a separate state.

"The governor of the state is doing nothing. Students are protesting for a separate state but he is not doing anything," said Karate Raju, a pro-Telangana protester.

The final decision on a new state lies with the Indian parliament. But the state assembly must also pass a resolution approving its creation.

K Tarakrama Rao, a pro-Telangana leader said: "It's extremely irresponsible. It's an insult to the democratic institution called parliament. It's an insult to Telangana as well."

The call for a separate Telangana state has been going on for some 40 years.

In December 2009, the government in the centre promised that Telangana would be formed.

With a population of 40 million, the proposed state comprises of 10 of Andhra Pradesh's 23 districts, including Hyderabad, India's sixth biggest city.

Anti-Telangana people fear that if a new state is carved out, India's IT hub of Hyderabad could become Telangana's new capital.

Meet the man who would make BlackBerry apps cool



BlackBerry Jam Americas 2012 keynote

The fate of Research in Motion rests on the success or failure of BlackBerry 10.



(Credit:
Jessica Dolcourt/CNET)



LAS VEGAS--Alec Saunders needed a little bait.


Soon after Saunders took over the developer relations team, he asked Research In Motion's then co-CEO Mike Lazaridis in October 2011 for 25,000 BlackBerry PlayBook
tablets. When Lazaridis asked why, Saunders said he intended to give them away.

"His jaw just dropped to the floor," Saunders told CNET. "He stood there flabbergasted."


Lazaridis ultimately agreed, and Saunders began giving PlayBooks out to developers. He followed that up by giving away more than 8,000 units of RIM's Dev Alpha devices, which ran an early version of BlackBerry 10.


Saunders knew he needed to get the long-ignored BlackBerry developer base excited again. In 48 out of the last 52 weeks, he has been on a plane circling the globe in an effort to drum up interest in every corner. Combine the mileage he and his team of nearly 100 evangelists have logged for RIM, and there would be enough to travel to the moon and back five times over, or 2.5 million miles.


"I took December off and took the time to get to know my wife," he quipped.


Saunders has embraced a concept that RIM had long ignored: that developers and a healthy app "ecosystem" can make or break an operating system. He's tried to make it more accommodating and responsive to developers. It's the touchy feely stuff RIM execs never thought was important.



"Development sentiment is crucial," he said. "Developer interest is a leading indicator of success for any platform."


There's a lot riding on BlackBerry 10, which after a series of delays is expected to be unveiled on Wednesday in New York. Having had no significant new product in more than a year, RIM needs a hit. Badly. Simply put, the BlackBerry operating system is in free fall. In the third quarter, the BlackBerry OS accounted for 5.3 percent of the market, a tick above Samsung Electronics' homegrown Bada OS (little more than a glorified experiment for the Korean handset giant), and less than half the 11 percent share it held a year ago, according to a Gartner study. In the same period,
Android's market share surged to 72.4 percent from 52.5 percent a year ago.


Now RIM has has to win back consumers who have long abandoned their BlackBerrys for iPhones and Android devices. It's planning a media blitz, complete with Super Bowl commercial. At the same time, BlackBerry has to compete against another upstart mobile operating system, Windows Phone by Microsoft, which is also seeking to be the No. 3 platform behind Google's Android and Apple's iOS.


Indeed, RIM has a long, tough road ahead of it, but credit Saunders for connecting with the developer community. When the operating system is unveiled, it will have 70,000 applications, which the company boasts is the most apps for a mobile platform at launch. Android had a little more than 50 apps at launch, but that was before the explosion of app development.

"I can't describe what (Saunders) achieved in one and a half years," CEO Thorsten Heins said in a recent interview. "I can't speak highly enough of him."


Of course, RIM will be going up against two ecosystems with an entrenched following. Apple, for instance, boasts of more than three-quarters of a million apps for iOS, while Android has more than 700,000 apps in the market. The Windows Phone Store has 125,000 apps, having doubled in size after the launch of Windows Phone 8 late last year.


Fresh start

I sat with Saunders earlier this month at the Consumer Electronics Show to talk about his efforts to convince skeptical developers to give BlackBerry another chance. I had arranged to meet with with him in the Rojo lounge of the Palms Place hotel, an extension of the Palms Casino Resort.

Rojo is a small, dark, and smoke-filled bar awash in red-neon accent lighting. A downed air-conditioning system meant a stiflingly hot environment, despite the windy and cold weather outside. It looked like hell, and that night, it felt like it too.

When I finally met up with Saunders and his entourage, which included a few public relations representatives and another developer evangelist, Tom Anderson, the heat in the bar forced us out to the minimalist and slate-dominated lobby for our sit-down chat.

Saunders wore a black suit jacket, button-down shirt, and blue jeans, and had just come in from a flight from Ottawa, Canada.

Saunders, a family man who leads a scout troop in his off hours, can't help but to come off as a nice, normal guy. He spoke in a calm and even tone with a slight Canadian accent. But his jovial and seemingly laid-back manner gave way to enthusiasm when talking about RIM's developer efforts.

"We're building a good head of steam behind us," he said. "Good things are happening."

Saunders had roots at RIM even before he joined the company in June 2011. He had previously worked at QNX before leaving to run his own start-up, a Web conferencing provider called iotum. QNX was eventually bought by RIM in April 2010, and its software forms the foundation for BlackBerry 10.

So it was a homecoming of sorts for Saunders when he joined RIM, right about when its market share started to collapse.

"It seemed like a good challenge to me," he said.

He made it clear he was a different sort of RIM exec. At one of his first public outings as vice president of developer relations, Saunders made the highly unusual move of posting his e-mail address while on stage at one of the company's many developer conferences.

"That was huge," said Jeremy Wall, a part-time BlackBerry developer who was in attendance at that conference and dabbled with the platform for the past decade. He, like everyone else in attendance, immediately grabbed his phone to update his contact list.


The result: a flood of e-mail that occupies a good chunk of Saunders' time. He received 14,793 e-mails -- in the last quarter alone. More recently, he's also taken to Twitter to answer questions, where he tweets under the user name @asaunders.

"My wife wasn't too happy with me," he joked during an interview with CNET shortly after that conference.


Fixing a broken system

The old RIM wasn't exactly friendly to developers. From complications signing up to fragmentation in the different versions of the BlackBerry operating system, creating an app for the platform could be a nightmare. One developer politely called it "rough," and said the company previously had the tendency to drop or ignore questions or concerns.


At the same time, iOS was beginning to generate interest from app developers. RIM executives, meanwhile, clung to the idea that e-mail and security were more important to users.

"Sometimes a good (butt)-whoopin' is what you need," said Michael Nowlin, who works for a cable set-top box manufacturing company but is an enthusiast and part-time developer known as "BlackBerry Hank."


"We're building a good head of steam behind us. Good things are happening.""
--Alec Saunders.




When Saunders joined, he knew RIM had big problems. So he made his pitch to the most loyal BlackBerry developers first before expanding to a broader audience.

Saunders laid out a model of responsiveness for which developers have expressed appreciation. When Wall, a part-time developer who also works at a manufacturer of weather stations, was setting up a local meet-up between BlackBerry developers and a RIM executive, he had hit a wall with the usual company contacts. When he e-mailed Saunders, he got a response back in 10 minutes and had an executive on his way to the meetup.

"I'll sing the praises of Alec Saunders all day for that," Wall said.

That new-found enthusiasm also attracted Nowlin, who is a relative newcomer to the BlackBerry ecosystem. He hopped on the bandwagon after seeing the kinds of tools and support available to him during a developer conference in June.

He likewise praised Saunders for his responsiveness and willingness to listen.

"He made me feel like he really cared, and he showed it," said Nowlin, a San Antonio native who works support for a set-top box manufacturer and develops BlackBerry 10 apps on the side.

While relations between developers and RIM improved, it was largely moot. With the older BlackBerry platform showing its age and the company moving to an unproven next-generation operating system, developers weren't too keen to take a chance, especially with the exploding potential coming from iOS and Android.


It was Saunders' idea of the PlayBook giveaway that got developers taking a more serious looking at RIM again.


Looking back, the PlayBook was ultimately more valuable as a relationship-building tool than a product. The much-hyped tablet launched in early 2011 with a thud, with only modest sales coming after heavy discounts and several software updates. To be fair, the PlayBook continues to sell, and the company shipped 255,000 units in the last reported quarter.

Early in the giveaway, RIM wasn't terribly choosy when handing over the PlayBooks -- a move Saunders said bought a lot of goodwill. But more recently, the company raised its standards and sought out developers with a genuine interest in the platform. At the last SXSW conference, developers were pitching RIM execs with half-finished apps before they were rewarded with a PlayBook to complete their work.


"RIM has done an astonishing job of getting developers to back a company which many people have completely written off," said Avi Greengart, an analyst at Current Analysis.


Time and money

While both the iOS and Android platforms can boast of massive user bases, RIM could only point to the PlayBook, a few thousand developer units and some fleeting glimpses of actual BlackBerry 10 products, which have faced multiple, frustrating delays.

As a result, there are still legions of developers who still veer away from RIM, considering it a risky bet next to the larger platforms. According to a June report by market analytic firm VisionMobile, the BlackBerry platform (old and new) is "very close to becoming an endangered species," with 41 percent of developers surveyed saying they were dumping the platform.


So Saunders and his team have shifted the conversation to address two other key concerns for developers: time and money.

RIM promised a much easier development process with BlackBerry 10. Regardless of the code or platform, it could easily be moved over to BlackBerry.


"Bring your code, and we'll find a way to make it happen," Saunders said.


RIM evangelist Anderson said he had gotten use to getting greeted with looks of skepticism when he went to talk to developers about BlackBerry. Now, he said he can turn them around after just a few minutes by showing them the simplified process of development and porting.


Equally important was the potential monetary return on a BlackBerry app. RIM executives told developers at a conference in May that it would guarantee that an app would generate $10,000 in revenue in their first year, or the company would make up the difference. (The fine print is that the app would have to be certified and generate at least $1,000 from downloads).


RIM has argued that its platform is a deceptively lucrative place for developers -- if you exercise a little math. If you remove the top 5 percent of highest-grossing apps, then BlackBerry's platform actually generates the most revenue, Saunders said. So for little-known developers without big brands, BlackBerry may prove to be a better home, he argued.

While fairly negative on BlackBerry's prospects, the VisionMobile report did note that a BlackBerry developer made an average of nearly $4,000 a month, or 4 percent better than the next best performing platform, iOS.


"The developer community that's behind them now is organic. They built it."

Beyond those factors, Saunders and his team has tried to directly talk to as many developers as possible. Since June, it has held 44 developer-focused BlackBerry Jam World Tour events and 11 Enterprise Jam events in more than 40 countries, hosting a total of nearly 10,000 developers. In addition to the launch on Wednesday, Saunders is preparing for BlackBerry Jam Europe next week.


There's little choice: These developers are essentially working on blind faith, with no actual products to work from and no proof that consumers will even buy them. Saunders and his team has had to apply a personal touch.


At least among its hardcore devotees, it's working.


"The developer community that's behind them now is organic," said George McKinney, an independent app developer based in Los Angeles. "They built it."

McKinney, who employs three people in a small development shop, primarily does work on iOS and Android apps, but said he works on BlackBerry 10 apps "because we have a lot of fun with it."


Singing a different tune

Saunders and fellow executives Chris Smith, vice president of application platform & tools, and Martyn Mallick, vice president of global alliances and business, were certainly having fun when they shot a music video set to REO Speedwagon's "Keep on Loving You."

When it was released on YouTube, the video -- and RIM -- became the target of ridicule from the press, who called it "awful" and feared it was a desperate and awkward attempt to woo developers.


Saunders' eyes lit up when I asked him about it, and it was clearly a labor of love. He said the developers enjoyed the video, and were captivated when it aired during its conferences. He said it was an attempt to break away from the usual "stupid energy clip" that precedes speeches and demos.

"We had a lot of fun with it," he said, teasing that one more music video was in the works.


Less light-heartedly, in the past few weeks, RIM has started to contact developers through e-mails and blog posts, pushing them to step up and get their apps ready in time for the launch this week.



In a last-minute scramble, Saunders earlier this month helped run an online "Portathon" that netted the submission of 15,000 apps for BlackBerry 10 after more than a day and a half.


"Well, there you have it...Feel like I've run a marathon," Saunders tweeted after the event.


For Saunders and the rest of RIM, the marathon to get the company back on track has just begun.

Doomed Dolphin Speaks to New York's Vibrant Wildlife


By the time New Yorkers spied a dolphin swimming through the superfund sludge of the Gowanus Canal last Friday, it was too late. The marine mammal didn't even survive long enough for a rescue plan to come together. First sighted on Friday afternoon, the dolphin perished at 6:00 p.m.

The reason the marine mammal died, and why the dolphin swam up the polluted waterway in the first place, is as yet unknown. But the sad story of the wayward creature highlights the strange nature of New York City, the global epitome of urbanity. Hidden within Gotham are native carnivores, marine mammals, and even species that have scarcely been seen before.

Marine mammals are arguably the most high-profile of New York City's wild residents and visitors. The Gowanus Canal dolphin was only the latest to venture within city limits. Just a month ago, a 60-foot-long finback whale (Balaenoptera physalus) became stranded in the Rockaway Inlet of Queens. The emaciated animal died the day after it was discovered.

There seems to be no singular reason explaining why marine mammals such as the Gowanus dolphin and Queens' finback whale wander up the city's rivers or strand on beaches. Each case is unique. But not all the city's marine mammal visitors suffer terrible fates.

In 2006, a hefty manatee (Trichechus spp.) took a long jaunt from its Florida home up the East Coast, including a detour down New York's Hudson River. The sirenian survived the trip, continuing on to Cape Cod before reportedly turning back south to a destination unknown. Hopefully the manatee didn't encounter any great white sharks (Carcharodon carcharias) on the return journey, a marine predator we know patrols the waters off New York.

Of course, New York City's whales, seals, and occasional manatee can only skirt the city along its shores and canals. You likely won't see a seal caterpillaring its way along Broadway.

Yet the city's interior also hosts a strange accumulation of wildlife, including native animals that are carving out spaces for themselves in the concrete corridors and exotic species that we have introduced to city life.

Coyotes (Canis latrans) may be the cleverest of New York City's hidden wildlife. Thanks to camera traps, and the occasional police chase through Lower Manhattan, researchers are keeping track of the wily canids and studying how they are so successfully taking up residence in many of the nation's cities. "Most small, urban parks will likely hold a pair and their offspring at most—coyotes are very territorial," said Cornell University ecologist Paul Curtis.

The secretive carnivorans bring a welcome element to urban neighborhoods—an appetite for rodents—and are experts at cracking open new niches alongside people.

Black bears (Ursus americanus) may be next. The bears have proliferated in northern New Jersey in recent years, and in 2010, a black bear came within three miles of the George Washington Bridge, a major thoroughfare between New Jersey and Manhattan. The bear obviously would have eschewed rush hour traffic and the tolls, but the local population is so bountiful that it's not unreasonable to think some enterprising bear might eventually wander into the big city.

Strangely, you may actually be more likely to run into a crocodylian predator in New York City than a black bear. New Yorkers have a nagging habit of importing—and losing-alligator—like caimans and other reptiles within the city.

In 2010, an 18-inch long caiman took refuge under a parked Datsun in Astoria, Queens. No one knows how the reptile wound up on the street, but given the trend of owners buying cute crocodylians and later dumping them, someone may have abandoned the poor little caiman.

This would hardly be the first time. In 2006, another little caiman was found in the leaf litter behind Brooklyn's Spring Creek Towers, while "Damon the Caiman" swam around a Central Park lake in the summer of 2001. These caimans are only some of the most famous—according to a New York Times report, the Brooklyn-based Animal Care and Control deals with about ten caimans each year.

Many other unusual and exotic animals have romped through New York. Under some of their most notable animal celebrities, the city's Parks and Recreation department lists guinea pigs, boa snakes, and even a tiger that escaped from a circus in 2004 and ran down Jackie Robinson Parkway before his owners were able to get him back.

The Big Apple even contains species that have never been documented before. No, not the ballyhooed "Montauk Monster"—actually a rotted raccoon—but a distinct species of leopard frog. Described early this year, the cryptic amphibian was given away by its unique mating call.
