Time to rinse! AI assistant helps clean your teeth









































FOR most of us, brushing our teeth is just a tedious part of the daily grind. But for people with dementia or learning difficulties, such tasks can be difficult. They could soon gain more independence thanks to an AI designed by Christian Peters at Bielefeld University in Germany and his colleagues.












Peters has already come up with a system that guides people when washing their hands. Brushing teeth is more complicated because it involves many steps - such as putting toothpaste on the brush, filling a glass with water or rinsing the mouth.












The TEBRA system uses a video camera to monitor someone brushing their teeth and checks that each step happens at the right time. It prompts them via a screen on the washstand if they forget a step or if they get stuck. The idea is not to dictate a routine, but to adapt to that of the user, says Peters.












TEBRA is being tested at a care home in Bielefeld for people with learning disabilities. Caregivers there reported that the system was less distracting for some people than a human carer. The work will be presented at the International Conference on Health Informatics in Barcelona, Spain, next week. Peters also plans to adapt his system to tasks such as shaving.

Rare exhibits dating back 150 million years to go on display






SINGAPORE: The first of what visitors to the upcoming Lee Kong Chian Natural History Museum's new building can expect to see were put on display recently including a prehistoric shrimp and an ancient relative of sea stars.

The exhibits are part of the collection that will be housed in the museum's new building at the National University of Singapore, as announced at the building's recent groundbreaking ceremony.

Singapore's Ambassador-at-Large and Honorary Chairman of Singapore's National Heritage Board, Professor Tommy Koh, graced the event.

Professor Koh first advocated the idea for a natural history museum for Singapore in 2004.

When completed in 2014, the new building is set to house one of the largest collections of Southeast Asian biodiversity in the region as well as three nearly-complete dinosaur fossils - fondly known as Prince, Apollonia and Twinky - from the Jurassic period.

Mars Rover Curiosity Completes First Full Drill


For the first time in history, humans have drilled a hole into rock on Mars and are collecting the powdered results for analysis, NASA announced Saturday.

After weeks of intensive planning, the Mars rover Curiosity undertook its first full drill on Friday, with NASA receiving images on Saturday showing that the procedure was a success.

Curiosity drilled a hole that is a modest 2.5 inches (6.35 centimeters) deep and .6 inches (1.52 centimeters) wide but that holds the promise of potentially great discoveries. (Watch video of the Mars rover Curiosity.)

"The most advanced planetary robot ever designed now is a fully operating analytical laboratory on Mars," John Grunsfeld, NASA associate administrator for the agency's Science Mission Directorate, said in a statement on Saturday.

"This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August."

The site of the much-anticipated penetration is a flat section of Mars rock that shows signs of having been underwater in its past.

Called Yellowknife Bay, it's the kind of environment where organic materials—the building block of life—might have been deposited and preserved long ago, at a time when Mars was far wetter and warmer than it is today.

The contents of the drilling are now being transferred into the rover's internal collection system, where the samples will be sieved down to size and scoured to minimize the presence of contamination from Earth. (Watch video of Curiosity's "Seven Minutes of Terror.")

Then the sample will be distributed to the two instruments most capable of determining what the rocks contain.

The first is the Sample Analysis on Mars (SAM), which has two ovens that can heat the powdered rock to almost 2000°F (1093°C) and release the rock's elements and compounds in a gaseous form.

The gases will then be analyzed by instruments that can identify precisely what they are, and when they might have been deposited. Scientists are looking for carbon-based organics believed to be essential for any potentially past life on Mars.

Powder will also go to the Chemistry and Mineralogy (CheMin) instrument for a related analysis that looks especially at the presence of minerals—especially those that can only be formed in the presence of water.

Louise Jandura, chief engineer for Curiosity's sample system at NASA's Jet Propulsion Laboratory, said that designing and testing a drill that can grab hold of Martian rock and commence first a percussive shallow drilling and then dig a deeper hole was difficult.

The drill, which is at the end of a 7-foot arm, is capable of about 100 discrete maneuvers.

"To get to the point of making this hole in a rock on Mars, we made eight drills and bored more than 1,200 holes in 20 types of rock on Earth," Jandura said in a statement.

Results from the SAM and CheMin analyses are not expected for several days to weeks.

LAPD Reopens Case of Suspected Cop-Killer's Firing













The Los Angeles Police Department announced today it will reopen the case of the firing of Christopher Dorner, but said the decision was not made to "appease" the fugitive former cop suspected of killing three people.


Dorner, a fired and disgruntled former Los Angeles police officer, said in the so-called "manifesto" he released that he was targeting LAPD officials and their families and will keep killing until the truth is known about his case.


"I have no doubt that the law enforcement community will bring to an end the reign of terror perpetrated on our region by Christopher Jordan Dorner and he will be held accountable for his evil actions," LAPD Chief Charlie Beck said in a statement released tonight.


He spoke of the "tremendous strides" the LAPD has made in regaining public trust after numerous scandals, but added: "I am aware of the ghosts of the LAPD's past and one of my biggest concerns is that they will be resurrected by Dorner's allegations of racism within the Department."


To do that, he said, full re-investigation of the case that led to Dorner's firing is necessary.


"I feel we need to also publicly address Dorner's allegations regarding his termination of employment, and to do so I have directed our Professionals Standards Bureau and my Special Assistant for Constitutional Policing to completely review the Dorner complaint of 2007; To include a re-examination of all evidence and a re-interview of witnesses," he said. "We will also investigate any allegations made in his manifesto which were not included in his original complaint.

"I do this not to appease a murderer. I do it to reassure the public that their police department is transparent and fair in all the things we do."


PHOTOS: Former LAPD Officer Suspected in Shootings


As police searched for Dorner today in the San Bernardino Mountains, sources told ABC News that investigators found two AR-15 assault rifles in the burned-out truck Dorner abandoned.


The truck had a broken axle, which may be the reason he decided to set fire to it, the police sources said.


A man identifying himself as Dorner taunted the father of Monica Quan four days after the former LAPD officer allegedly killed her and just 11 hours after he allegedly killed a police officer in Riverside, Calif., according to court documents obtained by ABC News


A man claiming to be Dorner called Randall Quan and told him that that he "should have done a better job of protecting his daughter," according to the documents.


In his 6,000-word "manifesto," Dorner named Randal Quan, a retired LAPD captain and attorney who represented him before a police review board that led to Dorner's dismissal from the force.


"I never had an opportunity to have a family of my own, I'm terminating yours," Dorner wrote, and directed Quan and other officials to "[l]ook your wives/husbands and surviving children directly in the face and tell them the truth as to why your children are dead."


Monica Quan and her fiancé Keith Lawrence were gunned down last Sunday in their car in the parking of their Irvine, Calif., condominium complex. Both were struck with multiple gunshot wounds.


The call, according to court records, was traced to Vancouver, Wash., but law enforcement officials do not believe Dorner was there at the time at the call.


Dorner is believed to have made the call early Thursday afternoon, less than half a day after he is suspected of killing a police officer and wounding two others early that morning, sparking an unprecedented man hunt involving more than a thousand police officers and federal agents spanning hundreds of miles.

Extreme life might be visible on colourful exoplanets








































Lichens and algae could be the first life forms we find on Earth-like exoplanets, by looking for their light signatures in a planet's distinctive colouring.












Astronomers have found several rocky worlds in the habitable zone, the region around a star where liquid water can exist on a planet's surface, and many more are thought to exist. As telescopes get more sensitive, we should be able to collect light reflected off such planets and look for clues to their surface conditions.












Seen from space, Earth gives off a large amount of near-infrared light, which is reflecting off the chlorophyll in plants. We might see a similar "red edge" on distant exoplanets if they also host green vegetation.













But Siddharth Hegde and Lisa Kaltenegger of the Max Planck Institute for Astronomy in Heidelberg, Germany, think it is possible that many rocky worlds will have extreme heat, dryness or acidity, and that hardier life forms will dominate their surfaces. So what would these organisms look like from a distance?











Patterns of life













To find out the pair looked at the light reflected by some of Earth's more extreme life forms: lichens in arid regions, bacterial mats in very hot water and red algae in acid mine drainage. They calculated that seen from afar each type of organism would create a unique colour pattern. Lichens, for instance, appear more yellow than the algae or bacteria.












Finding these patterns wouldn't necessarily mean life is present, but it could be a step towards narrowing down exoplanets for more detailed searches, the authors say.












It's an attractive idea, says Nicolas Cowan of Northwestern University in Evanston, Illinois, and it is far more likely that a given planet would contain microbial life than trees. But the work has its limits, he cautions. For instance, atmospheres on other planets may be very different from our own and could scatter light in ways we wouldn't expect.












"Nature may be more creative than our little corner of the cosmos would have us believe," Cowan says.

Changi Airport heralds in the LNY with auspicious floral displays






SINGAPORE: Changi Airport is all set to herald in the Lunar New Year decked in festive finery.

In recent years, florists have started to dye the white flowers in a variety of colours including red, blue and orange.

But horticulturalists said they've mostly hung on to tradition.

Manager at Changi Airport Operations Planning, Look-Tan Hwee Sung said: "Like hydrangea, in Chinese is called 'xiu jiu hua', it represents love. 'Fong mei' is related to 'fong huang', which means 'phoenix tail', which is related to prosperity. In the olden days, 'fong mei' was always in the royal family and things like that."

Most of the plants were grown locally or imported from the Cameron Highlands. And it took the 10-men horticulture team two months to select and design the flora displays.

Look-Tan Hwee Sung said: "The flowers are in full bloom because throughout the propagation period we feed them different types of fertiliser. Either you get cuttings or seed sowings, but we'll target for the date for it to bloom."

The 5th day of the Lunar New Year falls on 14 February which happens to be Valentines Day. So they've added a touch of romance to the terminals, along with Singapore's favourite couple - Kai Kai and Jia Jia.

The displays will be around until 6 March before making way for the next festive season.

Apple and the iWatch conundrum



Will Apple ever make an iWatch?



(Credit:
Sarah Tew/CNET)



Ever since the sixth-generation iPod Nano, lots of people have thought that Apple making its own branded watch is not merely a smart potential move but simply a matter of time. No matter what some have recently argued, I doubt, however, that today's Apple is hungry enough to create the fabled iWatch device.



I've been covering the technology beat long enough to feel, no, smell certain shifts in the gadget market. I'm talking about those cycles when a new product category springs up from nowhere and first seems like a completely goofy notion. Soon after, the segment really heats up with scores of companies jumping into the fray to make a quick buck.



Traditionally, if Apple senses a legitimate opportunity it steps in at the right moment after figuring out the secret to success and sucks the air right out of the market.
Tablets and MP3 players existed well before Apple launched the
iPod and iPad, but their arrival completely transformed the playing field. Remember music players from Creative Labs, Rio, or even Microsoft's clunky Windows Tablet PCs?


I'm getting the same tingling sensation right now from smartwatches. At
CES in January the sleeper hit of the show was wearable tech, essentially devices you could strap or clip to yourself as you would an accessory or article of clothing. A lot of smartwatches, fitness bands, or some hybrid of the two, were talked up at the conference.

These included everything from the long-awaited and crowd-funded Pebble and the Dick Tracy/007-inspired Martian Passport Watch to the Fitbit Flex fitness tracker and the Basis Band. When you factor in the success of the Nike FuelBand, Nike being a company Apple has partnered with in the past to create fitness products, I'd say the time is ripe for Apple to swoop in for the kill.

This is a move the Cupertino company used to accomplish without breaking a sweat. Apple has the knack of catching the competition completely flat-footed, surprising since many already had a big head start. The iPhone is a perfect example. Smartphones had existed for years but the iPhone sounded the death knell for Microsoft's struggling Windows Mobile products -- trust me, I was saddled with a T-Mobile Wing at the time. The Sidekick and a legion of keyboarded feature phones suffered the same fate.


I'm afraid Apple hasn't demonstrated its signature ferocity in recent years. We haven't seen a truly disruptive product from the company since the first iPad. Every noteworthy hardware release since then has been evolutionary and incremental, not transformative. The iPad Mini is simply a smaller iPad, while the iPhone 5 essentially increased the screen from 3.7 to 4 inches. Its A6 processor is also dual-core where many Android CPUs have gone to full quad-core and it received 4G LTE well after its rivals.

What Apple needs here is true out-of-the-box action to quell the doubters at large and on Wall Street. A serious example of nonlinear thinking that matches the creation of the iPod, iPhone, and iPad. Something that would merge multiple gadgets and applications into something entirely new or perhaps clean up the confused mess other manufacturers tout as useful gadgets. Something like a fabulous, shiny Apple iWatch.

Northeast Shuts Down as Blizzard Batters Millions













A blizzard of possibly historic proportions battered the Northeast Friday into Saturday, and forecasters feared as much as two feet of snow and strong winds could shut down densely populated cities such as New York and Boston, where cars were ordered off the streets.


State officials declared states of emergencies throughout the region, and utilities estimated more than a half-million customers were without power by late Friday night.


Some wondered if the storm could top Boston's all-time single-storm snowfall record of 27.6 inches, set in 2003.


By 9 p.m. Friday, according to the National Weather Service, the storm was spinning off the coast of Long Island, N.Y., and expected to move north-northeastward past New England's coast before its effects tapered off on Saturday afternoon.


"Storm total snowfall accumulations of 1 to 2 feet ... with locally higher amounts are possible across much of the Northeast," the National Weather Service said. "The heaviest snow is forecast to fall across parts of eastern Massachusetts ... Connecticut and Rhode Island where snowfall amounts higher than two feet are possible. In addition to the heavy snowfall ... wind gusts as high as 70 mph are possible ... especially near the coasts."


By 9 p.m. Friday, parts of Connecticut and New York had the highest actual snowfall totals listed by the National Weather Service, with 13 inches measured in Ogdensburg and East Setaukey, N.Y., and Lisbon and North Branford, Conn.


Peak wind gusts included a 71-mph measurement in Buzzards Bay, Mass., the National Weather Service said.


Power outages also were reported across the region. As of 11 p.m. Friday, for instance, approximately 300,000 Massachusetts customers were without power, ABC News station WCVB reported. Utilities also reported approximately 170,000 without power in Rhode Island, 30,000 in Connecticut and nearly 20,000 in New York.


The blizzard conditions came together after a storm from the west joined forces with one from the south to form a nor'easter.

The storm showed the potential for such ferocity that, before it even hit with full force, Massachusetts Gov. Deval Patrick declared a state of emergency Friday afternoon and signed an executive order banning vehicular traffic on roads in his state effective at 4 p.m. ET. It was believed that the last time the state enacted such a ban was during the blizzard of 1978. Violating the ban could result in a penalty of up to a year in jail and a $500 fine.


"[It] could definitely be a historic winter storm for the Northeast," said Adrienne Leptich of the National Weather Service in Upton, N.Y. "We're looking at very strong wind and heavy snow and we're also looking for some coastal flooding."


Airlines began shutting down operations Friday afternoon at major airports in the New York area as well as in Boston, Portland, Maine, Providence, R.I., and other Northeastern airports. By early evening Friday, more than 4,300 flights had been cancelled on Friday and Saturday, according to FlightAware. Airlines hoped to resume flights by Saturday afternoon, though normal schedules were not expected until Sunday.


The snow fell heavily Friday afternoon in New York City. Mayor Michael Bloomberg said clearing the roads was his main concern, and the city readied 1,700 snow plows and 250,000 tons of salt to clear the streets.


New York City was expecting up to 14 inches of snow, which started falling early this morning, though the heaviest amounts were expected to fall at night and into Saturday. Wind gusts of 55 mph were expected in New York City.


"Stay off the city streets. Stay out of your cars and stay at home while the worst of the storm is on us," Bloomberg said Friday.


Connecticut Gov. Dannel P. Malloy declared a state of emergency, deploying National Guard troops across the state to assist in rescues and other emergencies. Schools and state courthouses were closed, and all flights after 1:30 p.m. at Bradley Airport, north of Hartford, Conn., were cancelled. The state's largest utility companies planned for the possibility that 30 percent of customers -- more than 400,000 homes and businesses -- would lose power.


Malloy also directed drivers to stay off the state's major highways.


"Please stay off of 95, 91, 84, Merritt Parkway and any other limited-access road in the state," he said Friday evening.

Boston, Providence, R.I., Hartford, Conn., and other New England cities canceled school today.


"Stay off the streets of our city. Basically, stay home," Boston Mayor Tom Menino warned Thursday.


On Friday, Menino applauded the public's response.


"I'm very pleased with the compliance with the snow emergency," he said. "You drive down some of the roadways, you don't see one car."


Friday evening, Gov. Patrick also applauded the public's cooperation with the statewide vehicle ban, noting the clear roads were helping utility crews get their work done.


"It's been a great, great help and I thank everyone," Patrick said. "I know it's been an imposition."


As of 4:30 p.m. Friday, according to the Department of Defense, 837 National Guard soldiers and airmen under state control had been activated in Connecticut, Massachusetts and New York in anticipation of the storm -- 552 in Massachusetts, 235 in Connecticut and 50 in New York. The extra hands were helping with roadways, transportation, making wellness checks on residents and other emergency services.


Beach erosion and coastal flooding was possible from New Jersey to Long Island, N.Y., and into New England coastal areas. It was feared some waves off the coast could reach more than 20 feet.

Zoologger: 'It's a boy!' Monkey midwife delivers baby






















Zoologger is our weekly column highlighting extraordinary animals – and occasionally other organisms – from around the world






















Species: Rhinopithecus bieti
Habitat: Evergreen forests in an isolated mountainous area of south-west China












Humans aren't built for giving birth. Babies' heads are big to accommodate their big brains, but the mother's hips are small because they walk upright. As a result, birth takes hours and is extremely painful – and midwives almost always help out.












Other animals may find birth difficult, particularly if the babies have been gestating for a long time and have grown large. Nevertheless, most mammals have it easier than humans. Monkeys give birth in less than ten minutes.












So it is a surprise that female black snub-nosed monkeys may be assisted by "midwives" when they give birth. This behaviour has only been seen once in this species, but it suggests that it's not just human mothers that need help giving birth.












Black snub-nosed monkeys live in societies called bands, which can be over 400 strong. Each is divided into smaller groups of around 10 monkeys. Most groups contain one male and several females plus offspring, but there are also all-male groups.












Wen Xiao of Dali University in Yunnan, China, and colleagues have been observing black snub-nosed monkeys in the province for years, but had never seen one give birth: the monkeys normally deliver at night. Then on 18 March last year, they got lucky.











Rhododendron birth













A female monkey gave birth to her first infant within fifteen minutes late one morning. While sitting in a rhododendron tree, she began twisting her body and calling faintly. After 10 minutes she started screaming, and then another female climbed up the tree. She was an experienced mother, and sat beside the labouring female while the crown of the infant's head appeared. Once the head was fully exposed, the "midwife" pulled the baby out with both hands and ripped open the birth membranes.












Within a minute, the mother had reclaimed the infant from the midwife, severed the umbilical cord, and begun eating the placenta. A few minutes later, the midwife went back down to the forest floor to forage.












"This is a fairly rare observation," says Sarah Turner of McGill University in Montreal, Canada, who was not involved in the Yunnan study. She says female monkeys often pull their babies out themselves, and the midwife may have adapted this behaviour. "It's hard to know what's going on in her head," says Turner, but it seems she was genuinely helping.











That could be because female black snub-nosed monkeys tend to stay in the group they were born in. As a result, the females in a group are likely to be closely related and to have strong social bonds. Animals often help their relatives because doing so preserves their own genes, a phenomenon called kin selection.













The juvenile females in the group watched the birth closely, and may have picked up a few tips. Turner says many primates remain with their groups while giving birth, giving juveniles a chance to learn.











Survival aid













In a human childbirth, having help on hand can be vitally important should things go wrong, Wen notes. "The assistance means the infant has a better chance of surviving," he says. There could be a similar benefit for monkeys aided by a midwife.












But primates, with the exception of humans, rarely help each other give birth. In one case, a male cottontop tamarin was seen pulling at his infant's shoulders until they emerged. Another report claims that a female capped langur was groomed by other females during birth, perhaps in an attempt to ease her distress.












While primates generally give birth unassisted, other creatures get more help. In possibly the cutest observation in all of natural history, male Djungarian hamsters regularly assist with deliveries, pulling infants out with their front paws and incisors.
