Rescuers Search for Man as Fla. Sinkhole Grows

Rescuers early Saturday morning returned to the site where a sinkhole swallowed a Florida man in his bedroom after the home's foundation collapsed.

Jeff Bush was in his bedroom when a sinkhole opened up and trapped him underneath his home at 11 p.m. Thursday night.

While the sinkhole was initially estimated to be 15 feet deep on Thursday night, the chasm has continued to grow. Officials now estimate it measures 30 feet across and up to 100 feet deep.

Rescue operations were halted Friday night after it became too dangerous to approach the home.

Bill Bracken, an engineer with Hillsborough County Urban Search and Rescue team said that the house "should have collapsed by now, so it's amazing that it hasn't."

Using ground penetrating radar, rescuers have found a large amount of water beneath the house, making conditions even more dangerous for them to continue the search for Bush.

"I'm being told it's seriously unstable, so that's the dilemma," said Hillsborough County administrator Mike Merrell. "A dilemma that is very painful to them and for everyone."

Hillsborough County lies in what is known as Florida's "Sinkhole Alley." Over 500 sinkholes have been reported in the area since 1954, according to the state's environmental agency.

The Tampa-area home was condemned, leaving Bush's family unable to go back inside to gather their belongings. As a result, the Hillsborough County Fire Rescue set up a relief fund for Bush's family in light of the tragedy.

Officials evacuated the two houses adjacent to Bush's and are considering further evacuations, the Associated Press reported.

Meanwhile, Bush's brother, Jeremy Bush, is still reeling from Thursday night.

Jeremy Bush had to be rescued by a first responder after jumping into the hole in an attempt to rescue his brother when the home's concrete floor collapsed, but said he couldn't find him.

"I just started digging and started digging and started digging, and the cops showed up and pulled me out of the hole and told me the floor's still falling in," he said.

"These are everyday working people, they're good people," said Deputy Douglas Duvall of the Hillsborough County sheriff's office, "And this was so unexpected, and they're still, you know, probably facing the reality that this is happening."

Smartphone projector breathes life into storybooks

Hal Hodson, technology reporter

Remember your favourite storybook from childhood? Now imagine that the characters that graced its pages didn't only appear in print, but acted out scenes right in front of you, à la magic Harry Potter paintings.

HideOut, a smartphone projector system developed by Karl Willis at Disney Research in Pittsburgh, Pennsylvania, does exactly that by using invisible-ink markers to guide the projected characters of a storybook through an entire other layer of activities.

The projector also lets the user move a digital, animated character over surfaces in the real world. By passing the camera over another of the hidden patterns - which are visible only in infrared - the character can even seem to interact with physical obstacles, as in the video above.

In a paper describing the system, presented this month at the Tangible, Embedded and Embodied Interaction conference in Barcelona, Spain, Willis laid out how projection will move past games and playing to become an important computer-human interaction technology, freeing digital content from the screens.

Willis writes that future smartphones with embedded projectors will be used to browse digital files projected on any wall or table, to augment theme parks with digital characters, or to make digital board games that jump out of the table. "Enabling projected content to be mapped onto everyday surfaces from mobile devices is an important step towards seamless interaction between the digital and physical worlds."

Google CFO denies Samsung conflict

Google CFO Patrick Pichette played down reports that his company's relationship with Samsung was becoming strained and noted that "journalists love big headlines that sell newspapers."

Pichette was referring to a Wall Street Journal report this week noting Google was worried about Samsung's dominance.

Speaking at a Morgan Stanley investment conference, Pichette fired back:

We have a terrific relationship with Samsung. They've been very successful with the Android platform. They benefited just like the rest of the ecosystem. We welcome all of the partners that we have on our Android platform and continue to innovate. And what our objective and our aim is to make sure that as many partners in the ecosystem continue to benefit from these open source platforms.

I think that both Samsung and ourselves have benefited not only on the Android side but also on the Chrome side. The Chromebook is a runaway success; it's a runaway success for Google, it's a runaway success for Samsung. And so, what is not to like about these types of environments. I just think journalists love big headlines that sell newspapers.

Hardware was a recurring theme for Pichette, who touted Chromebooks as well as Google's acquisition of Motorola Mobility. Pichette said that the Motorola deal needs more time.

You invest for the long term, but we have inherited 18 months of pipeline that we actually have to drain right now and while we are actually building the next wave of innovation and product lines. And so far, as we said many times in the past, we have to go through this transition. This is not -- these are not easy transitions. We are very optimistic, we are very supportive and we have kind of great plans for Motorola. But for the coming -- for the last few quarters you have seen the announcements of restructurings and rationalization of product lines and this has to kind of continue over the next few quarters while we actually kind of make that cross over.

So there is still kind of really kind of hard work to be completed at Motorola before we see tangible signs. But we also very optimistic because since day one we have started working on the next agenda and we see that pipeline kind of showing up.

Regarding the Chrome OS, Pichette talked that topic up too. He said:

There is a better mousetrap and it has been invented and it is called Chrome OS. If you are in enterprise today the benefits of Chrome OS and the Chrome infrastructure is to have the equivalent of a desktop is one-sixth the price of a traditional answer.

And so if you are a 350 or 400 or 500 people kind of company, that is millions of dollars that you can reinvest into your business, because -- into the development of your product or the servicing of your product rather than just having sitting on your desk just a hardware and software just to run your business.

Not only that, but Chrome OS is actually immensely secure. The Chrome platform has been proven, you have seen these tests where we have these hacker weeks where we try to kind of that people break into the systems. And if you are a business, to actually have -- security is like oxygen to a business if you think of your data. You take it for granted until you have a breach and like everything kind of stops.

The Chromebook that was launched last fall has been a runaway success, absolute runaway success. We couldn't keep up with demand. And through the holidays and it has been a terrific kind of testimony that people want ease-of-use -- beautiful, simple -- there is a minimum standard they expect, but for the right price point they love the product.

Add it up and the overall message from Pichette was clear. Google is serious about hardware integration and melding its services even if it's efforts largely remain a work in progress.

Scarred Duckbill Dinosaur Escaped T. Rex Attack

A scar on the face of a duckbill dinosaur received after a close encounter with a Tyrannosaurus rex is the first clear case of a healed dinosaur wound, scientists say.

The finding, detailed in the current issue of the journal Cretaceous Research, also reveals that the healing properties of dinosaur skin were likely very similar to that of modern reptiles.

The lucky dinosaur was an adult Edmontosaurus annectens, a species of duckbill dinosaur that lived in what is today the Hell Creek region of South Dakota about 65 to 67 million years ago. (Explore a prehistoric time line.)

A teardrop-shaped patch of fossilized skin about 5 by 5 inches (12 by 14 centimeters) that was discovered with the creature's bones and is thought to have come from above its right eye, includes an oval-shaped section that is incongruous with the surrounding skin. (Related: "'Dinosaur Mummy' Found; Have Intact Skin, Tissue.")

Bruce Rothschild, a professor of medicine at the University of Kansas and Northeast Ohio Medical University, said the first time he laid eyes on it, it was "quite clear" to him that he was looking at an old wound.

"That was unequivocal," said Rothschild, who is a co-author of the new study.

A Terrible Attacker

The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History in Florida, speculate the creature was attacked by a T. rex.

It's likely, though still unproven, that both the skin wound and the skull injury were sustained during the same attack, the scientists say. The wound "was large enough to have been a claw or a tooth," Rothschild said.

Rothschild and DePalma also compared the dinosaur wound to healed wounds on modern reptiles, including iguanas, and found the scar patterns to be nearly identical.

It isn't surprising that the wounds would be similar, said paleontologist David Burnham of the University of Kansas Biodiversity Institute, since dinosaurs and lizards are distant cousins.

"That's kind of what we would expect," said Burnham, who was not involved in the study. "It's what makes evolution work—that we can depend on this."

Dog-Eat-Dog

Phil Bell, a paleontologist with the Pipestone Creek Dinosaur Initiative in Canada who also was not involved in the research, called the Edmontosaurus fossil "a really nicely preserved animal with a very obvious scar."

He's not convinced, however, that it was caused by a predator attack. The size of the scar is relatively small, Bell said, and would also be consistent with the skin being pierced in some other accident such as a fall.

"But certainly the marks that you see on the skull, those are [more consistent] with Tyrannosaur-bitten bones," he added.

Prior to the discovery, scientists knew of one other case of a dinosaur wound. But in that instance, it was an unhealed wound that scientists think was inflicted by scavengers after the creature was already dead.

It's very likely that this particular Edmontosaurus wasn't the only dinosaur to sport scars, whether from battle wounds or accidents, Bell added.

"I would imagine just about every dinosaur walking around had similar scars," he said. (Read about "Extreme Dinosaurs" in National Geographic magazine.)

"Tigers and lions have scarred noses, and great white sharks have got dings on their noses and nips taken out of their fins. It's a dog-eat-dog world out there, and [Edmontosaurus was] unfortunately in the line of fire from some pretty big and nasty predators ... This one was just lucky to get away."

Mysterious Escape

Just how Edmontosaurus survived a T. rex attack is still unclear. "Escape from a T. rex is something that we wouldn't think would happen," Burnham said.

Duckbill dinosaurs, also known as Hadrosaurs, were not without defenses. Edmontosaurus, for example, grew up to 30 feet (9 meters) in length, and could swipe its hefty tail or kick its legs to fell predators.

Furthermore, they were fast. "Hadrosaurs like Edmontosaurus had very powerful [running] muscles, which would have made them difficult to catch once they'd taken flight," Bell said.

Duckbills were also herd animals, so maybe this one escaped with help from neighbors. Or perhaps the T. rex that attacked it was young. "There's something surrounding this case that we don't know yet," Burnham said.

Figuring out the details of the story is part of what makes paleontology exciting, he added. "We construct past lives. We can go back into a day in the life of this animal and talk about an attack and [about] it getting away. That's pretty cool."

Fla. Man Swallowed by Sinkhole, No Signs of Life

A Florida man has disappeared into a 30-foot-wide, 20-foot-deep sinkhole that collapsed the bedroom portion of his home overnight, according to police.

The hole opened up at around 11 p.m. Thursday night in the Brandon, Fla., neighborhood, authorities said.

"[The family] heard a sound that they described as a car crash emanating from the bedroom in the back of the house," Hillsborough County Fire Chief Ron Rogers said at a news conference today.

The family rushed into the room where Jeff Bush, 36, was sleeping, according to ABC News' Tampa affiliate WFTS-TV.

"All they could see was part of a mattress sticking out of the hole. Essentially, the floor of the room had opened up," Rogers said. "They could hear the nephew in the hole, but they could not see him."

Bush's brother, Jeremy Bush, jumped in and tried to rescue him, but was unsuccessful. A first responder "heroically" jumped in and rescued the brother, Rogers said.

The family was evacuated from the home as rescuers tried to get to the man.

Listening devices and cameras were sent into the hole.

"They did not detect any signs of life," Rogers said. "There continued to be collapses of the earth below the floor to the point where they had to eventually back out of the house."

Rogers said the main issue right now is that authorities and rescuers do not know how stable the house is.

It was previously reported that the hole was 100-feet wide, but Bill Bracken, president of Bracken engineering, clarified at the news conference that the safety zone around the hole is 100 feet, but the hole itself is between 20 to 30 feet in diameter.

It is contained within the footprint of the house, he said.

"The hole has actually taken up most of the inside of the house," Bracken said. "It started in the bedroom and has been expanding outward and it's taking the house with it as it opens up."

When asked what authorities believe the victim's status is, Rogers said, "Until we can actually determine where the victim is, I can't really answer that. We're going to do everything we can for Mr. Bush, but we have to make sure we don't endanger other personnel in the process."

Rogers said "time is a critical thing" and they are assessing the situation as quickly as possible without jeopardizing anyone else.

"We're not going to leave until we know that this community is safe and we know the extent of this issue here," he said. We're going to make sure that everyone is safe as much as we can. We don't know where the next sinkhole is going to open."

Police evacuated the other residents from the structure, as well as the two surrounding homes. Officials say the home could go at any moment.

"Our hearts go out to the Bush family during this terrible time," he said. "They're dealing with a lot of questions, a lot of unknowns."

Canine intelligence tests reveal how dogs think

Sandrine Ceurstemont, editor, New Scientist TV

Think your dog is smarter than most? Now you can put the pooch through a series of science-based tests that reveal its cognitive style.

Developed by Brian Hare from Duke University in Durham, North Carolina, and colleagues, a new website called Dognition allows dog owners to see how their pets fare in experiments exploring memory skills, cunning, empathy and even knowledge of physics. In this video, a dachshund and a mixed breed visit the New Scientist office to pit their wits against the games. Each dog often responds differently to cues from its owner: Ginny the dachshund, for example, was reluctant to disobey her owner when her back was turned, whereas Leicester, our other dog subject, immediately steals the treat.

The team will be using the information gathered through the website to gain a better understanding of how dogs think. By using "citizen science", they can quickly get large amounts of data compared with conducting the research themselves.

Hare is interested in the behaviour of domestic dogs because it gives insight into our own evolution. "The dog is the only species we've found that has some of the communicative skills that look like what infants need to acquire language and culture," he says. Canines learn words by inference, much like human babies, and can read their owners' gestures, something that even chimps and bonobos are incapable of. For more on the human-dog connection, check out our interview with Hare, "Old dog tricks: The survival of the friendliest".

Scientists link two rats' brains, a continent apart

PARIS: Creating a "superbrain" of connected minds, scientists on Thursday said they had enabled a rat to help a fellow rodent while the animals were a continent apart but connected through brain electrodes.

With electrodes imbedded in its cortex, a rat in a research institute in Natal, Brazil sent signals via the Internet to a counterpart at a university lab in Durham, North Carolina, helping the second animal to get a reward.

The exploit opens up the prospect of linking brains among animals to create an "organic computer", said Brazilian neurobiologist Miguel Nicolelis.

It also helps the quest to empower patients stricken with paralysis or locked-in syndrome, he said.

"We established a functional linkage between two brains. We created a superbrain that comprises two brains," Nicolelis said in a phone interview with AFP.

Published in the journal Scientific Reports, Nicolelis' team gave basic training to thirsty rats, who had to recognise lights and operate a lever to get a reward of water.

They then implanted ultra-fine electrodes in the rats' brains, which were linked by a slender overhead cable to a computer.

In a glass tank in Natal, the first rat was the "encoder", its brain sending out a stream of electrical pulses as it figured out the tricks for getting the reward.

The pulses were sent in real time into the cortex of the second rat, or "decoder" rat, which was facing identical apparatus in a tank in North Carolina.

With these prompts from its chum, the decoder rat swiftly found the reward in turn.

"The pair of animals collaborated to solve a task together," said Nicolelis.

What the second rat received were not thoughts, nor were they images, Nicolelis said.

When the encoder rat achieved various tasks, the peaks in his brain signals were transcribed into a telltale pattern of electronic signals that were received by the decoder rat.

Once the rat recognised the usefulness of these patterns, they became incorporated into its visual and tactile processing.

"The second rat learns to recognise a pattern, a statistical pattern, that describes a decision taken by the first rat. He's creating an association of that pattern with a decision," said Nicolelis.

"He may be feeling a little tactile stimulus, but it's something that we don't know how to describe because we cannot question the subject."

The linkage "suggests we could create a brain net, formed of joined-up brains, all interacting," the scientist said, hastening to stress that such experiments would only be conducted on lab animals, not humans.

"If you connect several animal brains, rat brains or primate brains, you probably could be creating an organic computer that is a non-Turing machine, a machine that doesn't work according to the Turing design of all the digital computers that we know. It would be heuristic, it wouldn't use an algorithm, and it would uses probabilistic decision-making based on organic hardware."

Still unclear is how the decoder animal incorporates the encoder's signals into its mental space, a phenomenon called cortical plasticity.

"We basically show that the decoder animal can incorporate another body as an extension of the map that the animal has in it's own brain," said Nicolelis, adding, though: "We don't know how this is done."

Nicolelis carries out research at Duke University in Durham and at the Edmond and Lily Safra International Institute for Neuroscience of Natal, or ELS-IINN.

A decade ago, he leapt to prominence for pioneering work in having lab monkeys move a robotic arm through brain impulses.

The latest work should help this, he said: "We are learning ways to interact with and send messages to the mammalian brain that will be fundamental for our goals of medical rehabilitation."

His next goal is to have a paraplegic patient give the official kickoff to the 2014 World Cup in Brazil, using a brain-machine interface to activate an artificial limb.

Practical, affordable phones take center stage at MWC 2013

Firefox's new mobile OS in action on the Geeksphone Peak

Although mobile phones will always have a central role at Mobile World Congress, this year's the red-hot buzz went to software, tablets, wearable tech, and other geeky-cool oddities.

With heavy hitters HTC announcing its flagship HTC One days before MWC, and Samsung saving its Galaxy S4 announcement for March 14, it was the sensible, midrange
Android phones made up the bulk of the announcements.

However, it was the outlier operating systems that really stole the show.

Firefox, Ubuntu, Tizen: The other, other OSes

The mobile, browser-based Firefox OS appeared on several smartphones, like the Geeksphone Peak (our pick of the bunch,) Alcatel One Touch Fire and ZTE Open.

LG and Huawei Firefox phones also made an appearance under glass, and
Firefox has locked down carrier partners to bring its -- frankly, rather green -- OS to emerging markets for cheap.

Ubuntu Touch OS impressed on an LG Nexus 4 and Google Nexus 7 tablet, and Samsung's Tizen OS came out for an early look.

The usual suspects

MWC 2013 saw a mini trend of large-screen devices (you might call them phablets,) like the LG Optimus G Pro, ZTE Grand Memo, and the Alcatel One Touch Scribe Easy.

There was also a larger trend of wallet-friendly options like the Samsung Galaxy Grand, Alcatel One Touch Snap, and Acer Liquid E1 and Liquid Z2.

On the Windows Phone side, Nokia took top honors with the Nokia Lumia 720, a nice midrange Windows Phone 8 device with many of the features you also see on the higher-end Lumia 920.

A step below, the Lumia 520 is notable for its low price, but strong feature set -- 139 euros (a little under $200) unlocked. U.S. customers should pay attention, since a variant will also arrive on T-Mobile as the 521.

Weirder fare

We also enjoyed uniques like the rugged Cat B15 Jelly Bean smartphone and the dual-screen NEC Medias W N-05E.

In non-smartphone land, and an emergency cell phone, SpareOne Plus, which runs on a AA battery. The Nokia 105 also made headlines for its ridiculously low retail price of 15 euros.

As with
CES last month, MWC 2013 gave the smaller brands a chance to prove their worth.

Why African Rhinos Are Facing a Crisis

The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."
