The smartphone apps that could save your life

London, England (CNN) -- There are a growing number of smartphone applications aimed at assisting medical professionals or improving personal health.

From AirStrip OB, which lets obstetricians remotely access real-time data about newborn babies, to Epocrates, a kind of drug encyclopedia for medics, phone apps have the potential to be lifesavers.

Then there are the apps aimed at improving people's general health, such as RunKeeper, designed to make it easier to keep fit, and Absolute Fitness, which could help you keep tabs on your diet.

We take a look at just a few of the health-related applications now showing on a smartphone near you.

STORY HIGHLIGHTS
  • MIT team was first to discover the locations of 10 balloons scattered across U.S.
  • Contest tested use of Web-based techniques to achieve time-critical tasks
  • Challenge was announced on anniversary of first message sent on Internet's precursor
  • DARPA: Winning team discovered balloons' locations less than nine hours after launch

(CNN) -- A team from the Massachusetts Institute of Technology won $40,000 in a high-tech scavenger hunt on Saturday by discovering the location of 10 red weather balloons.

The Defense Advanced Research Projects Agency announced that the MIT team was the first group in the contest to report the latitude and longitude coordinates of all 10 balloons, which were scattered across the United States.

DARPA is the U.S. military's research arm. Saturday's challenge is the latest in a series that the agency has hosted since 2004.

This contest was designed to test the way social networking and lesser-known Web-based techniques can help accomplish a large-scale, time-critical task.

DARPA said in a written statement that the MIT team discovered the locations of the 8-foot-wide balloons less than nine hours after they launched, around 10 a.m. ET.

It did not say exactly when the task was completed or how many groups had participated.

Johanna Jones, a spokeswoman for DARPA, said the hunt was designed in part to give the military new ideas on ways to operate in a range of situations, from natural disasters to combat.

The agency said it plans to meet with teams to discuss their approaches and strategies used to build networks, collect information, and participate in the contest.

The challenge was announced on October 29 -- 40 years after the first message was sent on ARPANET, the precursor to the Internet. DARPA said it hopes the contest will lead to advances in the way the military communicates and coordinates activities among multiple geographically separated groups.

On MIT's Web site, a link was posted inviting people to sign up to help find the balloons and urging them to invite their friends. It said the MIT Red Balloon Challenge Team "is interested in studying information flow in social networks, so if we win, we're giving all the money away to the people who help us find the balloons!"

It detailed a chain for giving away the money, beginning with $2,000 given to each person who first sent in the coordinates of each balloon.

"We're giving $2,000 per balloon to the first person to send us the correct coordinates, but that's not all -- we're also giving $1,000 to the person who invited them. Then we're giving $500 whoever invited the inviter, and $250 to whoever invited them, and so on..." it said.

It was not immediately clear how many people participated for MIT.

The hidden costs of identity theft

By John Blake, CNN

The identities of an estimated 9.1 million Americans have been stolen, according to a 2008 survey.

STORY HIGHLIGHTS
  • The toll of identity theft includes financial and emotional costs
  • An estimated 9.1 million Americans have had identities stolen, according to a 2008 survey
  • Security experts: Recovery takes months, if not years
  • The Internet has made identity theft easier and more widespread
RELATED TOPICS

(CNN) -- Debra Guenterberg doesn't have to go to a horror movie to get spooked. She says she's been living a nightmare for the past 13 years.

The Wisconsin woman says she's been stalked by two phantoms. Two men stole her name and her husband's Social Security number. They used the information to obtain credit cards, buy cars and three homes.

Like many horror movie villains, the bad guys keep coming back. Thirteen years after the men stole their names, the Guenterbergs are still being turned down for credit because of the damage done by the men, she says.

"It's a nightmare," Guenterberg says. "We both feel physically and mentally exhausted. We feel hopeless because we can't fix this."

Most people know about the financial hit identity theft victims take. But less attention is paid to the emotional costs they also pay. Victims often experience paranoia, depression, rage -- some even endure family breakups, security experts say.

There are many ways someone's identity can be stolen. Much of it now occurs online. A person's identity can be stolen from a social media site, through online banking or after they have clicked on a deceptive e-mail.

But no matter how it happens, the victim is going to pay -- financially and emotionally, cybersecurity officials say.

The Guenterbergs say they've battled the IRS, elected officials and local sheriffs to reclaim their name. They've also undergone counseling.

"We're angry," Debra Guenterberg says. "We can't sleep at night. ... We want to move on."

The hidden toll of ID theft

Moving on, though, often requires justice. And that can be elusive for victims of identity theft, security experts say.

The identities of an estimated 9.1 million Americans have been stolen by thieves lifting personal information off the Internet or through other means, according to a 2008 survey conducted by Javelin Strategy & Research, a financial services research firm.

But it often takes the average identity theft victim months, if not years, to resolve their case, security experts say. Some say that no matter what they do, they still encounter problems getting credit.

Robert Guenterberg tried to open a checking account earlier this year, but says the bank turned him down because it confused him with the men who had stolen his Social Security number.

"It never ends," Robert Guenterberg says.

The Guenterbergs say their ordeal began 13 years ago when Robert Guenterberg tried to buy a Ford truck but was rejected because of poor credit. He got the same answer when he tried to get a home loan and a credit card.

When the collection agencies started calling, the Guenterbergs say they finally discovered the source of their problem. They say two men had stolen the couple's name and Robert' Guenterberg's Social Security number.

The Guenterberg's situation was especially thorny because it involved the loss of his Social Security number.

The Privacy Rights Clearinghouse, a nonprofit group that educates consumers about privacy protection, tells people that even if an imposter is using their Social Security number, the Social Security Administration will only issue a new number in extreme cases.

Michael Kaiser, executive director of the National Cyber Security Alliance, says getting a new Social Security number is tough and can complicate an identity theft victim's life even more.

"They can [get a new Social Security number] but the hassle may not be worth it," Kaiser says.

What the scammers say after they've been caught

Even if victims of identity theft are able to clean up their financial records, some must learn how to overcome their bitterness. Linda Foley had to learn that lesson.

Foley had just started working as a restaurant reviewer for a San Diego magazine when her employer asked her to fill out tax forms to get paid.

Foley says her employer then used her Social Security number to obtain three credit cards and a cell phone. She says she uncovered the deception when one of her credit card companies called during a routine credit check to verify her change of address.

That's when Foley learned that her boss was living it up on credit cards with her name.

"She was getting gourmet meals home delivered," Foley says. "She was getting vitamins; she was going on shopping sprees at department stores."

Foley says she's not the same person she was before her identity was stolen.

"It changes your life," she says. "I don't trust the way I used to. I don't share things with people as much as I used to."

Foley says she never talked to the woman who stole her identity, but she always wanted to.

The woman was eventually caught and apologized to a judge in court for stealing Foley's identity. Foley was so angry that she wanted to personally confront the woman. But Foley says her lawyer restrained her.

"I came to understand that what she did was because of what she is," Foley says. "How could she explain that to anybody? They [scammers] live a different life; they live in a different world."

Foley says she and her husband, Jay, formed Identity Theft Resource Center, which educates individuals and businesses about identity theft. In her new role, Foley says she talked to identity theft scammers.

None of them saw themselves as criminals, she says.

"The reason they gave is, 'No one is going to get hurt,' '' Foley says. "They don't see this as a crime of victimization."

Some identity thieves are so cold-blooded that they even prey on their closest relatives, Foley says.

"I've worked with people whose parents have stolen their information for 25 years," Foley says. "They've had their parents jailed."

Tips for preventing identity theft are now well known. Only give out a Social Security number if you must; install a firewall on your home computer; don't use biographical information in your passwords.

Linda Foley's husband, Jay, co-founder of Identity Theft Resource Center, says one of the best precautions a person can take is something simple: Pay attention to what they click on the Internet.

"You get yourself into a big rush and something pops up in front of you, you deal with it and move and then you say, 'What did I just do?' " says Jay Foley.

Perhaps one of the best precautions is to remember the struggles of people like the Guenterbergs.

Losing money to a thief is not the same as losing one's identity, Debra Guenterberg says.

"If somebody steals your wallet and you notice what they've done on your credit report, you still have protection from that, though it's still a nightmare, '' Debra Guenterberg says.

"But when someone overtakes your life and becomes you -- that's insane."

Discovery Brings Dinosaurs Roaring to Life

Saturday, December 05, 2009
By Jeremy A. Kaplan

65 million years after they ruled the planet, dinosaurs are back.

A new four-part miniseries on the Discovery Channel peels back the millennia and the skin, revealing a never before seen look at the birth and death of dinosaurs.

Researchers have made incredible leaps in the last year or two, learning previously unknown details about how the giant creatures were born, smelled, thought, acted and more. This Sunday at 8 p.m., a new series captures those advances like never before.

"Dinosaur science really evolves on an annular basis. So much changes year after year," explains "Clash of the Dinosaurs" executive producer Bill Howard to FoxNews.com in an exclusive interview.

"The series sets out to gather the sum total of today's paleontology and scientific knowledge about dinosaurs, letting viewers see what these creatures were like as animals, not prehistoric monsters."

SLIDESHOW: A sneak peek at "Clash of the Dinosaurs"

There have also been mighty steps forward in computational power and computer-rendering ability. Discovery's artists used these advances in graphics to depict dinosaurs as never before, letting viewers to see deep inside the body of a dinosaur.

"We took apart the anatomy of the different dinosaurs themselves, and really got into the cutting edge of how they moved, appeared, and behaved," said Howard. To study the muscles, tissues, and brain functions of creatures dead for tens of millions of years, Discovery relied upon the expertise of consulting anatomists and paleontologists, giving a previously unexplored look at dinosaur tendons and tissue.

"We're starting to understand where muscle attached to bone, how skin looked, how it resembled (or didn't) modern animals," said Howard."We've taken walk cycle models and anatomy and put it together with the correct weight and mass and how the muscles would have to move in order to move the joints and so on. With photo-realistic computer graphics, you see what the animals would have looked like when they moved."

"When you see the animals move, you see the skin responding to their movements, the effects of rain hitting their hides," he gushes.

Beyond mere anatomy, the show explores new theories about these powerful animals. For example, conventional wisdom holds that the fearsome Tyrannosaurus rex had a brain like a walnut, limiting its actions to reactions, fight or flight mechanisms. But modern science suggests the T. rex had a large brain capable of complex behaviors. The show depicts the incredibly maternal instincts and family bonding scientists now think was commonplace among the gigantic animals.

Flying reptile Quetzalcoatlus (named after the Aztec god) had a 40-foot wingspan. "We figured out how it's anatomy worked and how it was able to fly for extended periods," adds Howard. Given the creature's weight and size, paleontologists speculated that it lived in an area where it took off from cliffs and soared like a glider. "We've discovered that their leg muscles had the quick reflexes of a frog, so unlike a modern bird, it could leap into the air very readily." Howard also notes that the creatures had tremendous eyesight, seeing in ultraviolet to following the urine trails of its prey.

"These creatures are no longer mysterious, they're more closely related in how they see, think and move to modern animals than you might think."

Scientists, Lawyers Mull Effects of Home Robots


Sunday, December 06, 2009

PALO ALTO, Calif. — Eric Horvitz illustrates the potential dilemmas of living with robots by telling the story of how he once got stuck in an elevator at Stanford Hospital with a droid the size of a washing machine.

"I remembered thinking, `Whoa, this is scary,' as it whirled around, almost knocking me down," the Microsoft researcher recalled. "Then, I thought, `What if I were a patient?' There could be big issues here."

We're still far from the sci-fi dream of having robots whirring about and catering to our every need. But little by little, we'll be sharing more of our space with robots in the next decade, as prices drop and new technology creates specialized machines that clean up spilled milk or even provide comfort for an elderly parent.

Now scientists and legal scholars are exploring the likely effects. What happens if a robot crushes your foot, chases your cat off a ledge or smacks your baby? While experts don't expect a band of Terminators to attack or a "2001: A Space Odyssey" computer that takes control, even simpler, benign robots will have legal, social and ethical consequences.

"As we rely more and more on automated systems, we have to think of the implications. It is part of being a responsible scientist," Horvitz said.

Horvitz assembled a team of scientists this year when he was president of the Association for the Advancement of Artificial Intelligence and asked them to explore the future of human-robot interactions. A report on their discussions is due next year.

For years, robots have been used outside the home. They detect bombs on the battleground, build cars in factories and deliver supplies and visit patients in hospitals.

But the past few years have seen the rise of home robots. Mainly they are used for tasks like vacuuming (think Roomba). There are also robotic lawn mowers, duct cleaners, surveillance systems and alarm clocks. There are robotic toys for entertainment, such as Furby. Robotic companions, like Paro the harbor seal, comfort the elderly. By 2015, personal robot sales in the U.S. will exceed $5 billion, more than quadrupling what they are now, according to ABI Research, which analyzes technology trends.

"You won't see Rosie from `The Jetsons,' but you're going to see more and more robots that help maintain your home. They'll pick up stuff off the floor, stock your fridge, carry stuff from the car," said Colin Angle, CEO of iRobot Corp., which makes the Roomba.

As such 'bots become more sophisticated, they could complicate questions about product liability. Ryan Calo, a fellow with Stanford's Center for Internet and Society, pointed out in a recent panel discussion at Stanford Law School that the original manufacturer might not always be liable if a robot went haywire.

"Robots are not just things the manufacturer builds and you go out and use them in a specific way. Robots can often be instructed, they can be programmed, you can have software that is built upon by others," he said.

There are no laws in the U.S. specifically governing robots, and discussion of them usually leads to science fiction writer Isaac Asimov's Three Laws of Robotics, which debuted in his 1942 short story "Runaround."

The first of Asimov's laws is that robots should do no harm. It's also one of the biggest considerations when manufacturing the next generation of personal robots.

"If a robot becomes increasingly autonomous and can make its own decisions, what happens if the robot does not carry out the exact wishes of the person?" said George Bekey, a robotics researcher and professor emeritus at University of Southern California.

As robots interact more closely with people, the bonds some people form with the machines — even ones that do not look like humans — might need to be considered.

Shoppers personalize their Roombas, naming and decorating them, for example. Angle recalled an incident when a soldier plucked a banged-up military robot nicknamed Scooby from an Iraqi battlefield and carried it to a depot to be fixed.

"It's doing you a service, you're going to get attached to it," Angle said.

Ronald Arkin teaches a course on robots and society at Georgia Tech and directs the school's Mobile Robot Laboratory. His most recent book is titled "Governing Lethal Behavior in Autonomous Robots."

"There needs to be ethics embedded in the systems," he said. "It's not just making a system that assists someone. It's making a system that interacts with someone in a way that respects their dignity."

Horvitz said his panel will recommend more research into the psychological reactions humans have to robotic systems. The group, he said, also suggests machines be designed with the ability to explain their reasoning to humans.

While ethicists, lawyers and roboticists ponder how to best integrate humans and autonomous machines, there is some evidence that a balance is already beginning to be struck.

After returning to the Stanford hospital on another occasion, Horvitz noticed a sign hanging above the spot where he had his harrowing experience. It read: "Please Do Not Board The Elevator With The Robot."

A day in the 'normal' life of a Nobel Prize winner


By Val Willingham, CNN Medical Producer
December 7, 2009 9:12 a.m. EST
Dr. Carol Greider, center, was feted by her son, daughter and her colleagues at Johns Hopkins School of Medicine on October 5, the day it was announced that she won the Nobel Prize for Medicine.
Dr. Carol Greider, center, was feted by her son, daughter and her colleagues at Johns Hopkins School of Medicine on October 5, the day it was announced that she won the Nobel Prize for Medicine.

Watch for Health Minute on HLN, 10 a.m.-6 p.m. ET weekdays.

Baltimore, Maryland (CNN) -- She was folding laundry when the call came at 5 a.m. After she hung up the phone, Dr. Carol Greider went upstairs to wake her children. She had to tell them, even if it meant getting them out of bed early.

"I said, 'By the way, I just won the Nobel Prize. You can go back to sleep now,' " she recalled.

Until this past October, many would have described Greider as your typical working woman. A molecular biologist at Johns Hopkins School of Medicine and the mother of two children -- Gwendolyn, 10, and Charles, 13 -- she splits her time between job and family. But "typical" no longer applies.

Winning the 2009 Nobel Prize for Medicine may help her career, but it hasn't changed her attitude about home life. "I could have basked in the moment, but I had to tell my kids first. And they were thrilled, but then they wanted to know, 'Do we have to go to school today?' " she said. "Of course I said, 'No, you don't.' And they came to work with me."

The Nobel Prize and Prize in Economic Sciences have been awarded to women 41 times between 1901 and 2009. Only one woman, Marie Curie, has been honored twice. Ten women, including Greider, have received it for medicine, others for economics, physics, literature and chemistry; 12 have won the Nobel Peace Prize. But few have been single moms, whose thoughts are just as consumed by homework as by helices.

Watch more on Dr. Carol Greider's juggling act

It's not like the Academy Awards, where you know you may be up for it. It just comes with a phone call.
--Dr. Carol Greider, Nobel Prize winner

Greider, 48, along with her mentor Dr. Elizabeth Blackburn from the University of California, San Francisco, and Harvard scientist Dr. Jack Szostak, were given the Nobel Prize for their work with telomeres, which are the bits of repeating DNA at the end of our chromosomes. Telomeres protect the chromosomes, much like the plastic tips on shoelaces keep lace from fraying.

The research team was also recognized for its discovery of telomerase, which is the enzyme that causes the chromosome ends to stay intact when they divide. Understanding telomerase is important when looking for clues about aging and cures for degenerative diseases and cancer.

Born into a family of scientists -- her mother was a biologist; her father was a physicist -- Greider knew her passion was in the lab. And although she suffered from dyslexia, her stellar grades got her into graduate school at the University of California, Berkeley, where she worked with Blackburn.

Blackburn had been looking for an enzyme that helped telomeres stay intact. But it was Greider who had the "Eureka!" moment during routine research. She actually discovered the enzyme, telomerase, while making a random, small change in her experiment. The rest, as they say, is scientific history.

"At the time we made this discovery, it was just a fundamental, curiosity-driven question," she said. "But we've been able to link that up to important medical consequences."

Although the initial discovery happened 25 years ago, Greider knew there was always a chance the Nobel Committee could recognize her accomplishments. "Every year or so, I was told maybe this year, it could happen, this could be the year," she said. "But there are no nominees -- it's not like the Academy Awards, where you know you may be up for it. It just comes with a phone call."

I live a pretty normal life.
--Dr. Carol Greider, Nobel Prize winner
RELATED TOPICS

So when the call did come, it was a shock to Greider -- but a pleasant one. She is taking 16 friends and relatives to Stockholm, Sweden, to be with her when she receives her prize December 10. There will be parties and seminars to attend, and she wants it to be a special moment for everyone, especially for her children: "I want to pick the best events for them so they aren't bored and they can always remember it and be able to share the moment with me."

As for the money -- she'll split the $1.4 million purse three ways -- she's still not sure what she'll do with it. "I'd like it if it could give me more freedom to work in the lab, which is my first love. And I'd like to imagine all the wonderful things it could bring to my future," Greider said, before returning to reality. "But right now, my kids are in school, and I still have to make them lunches and dinners. And all that will keep me grounded."

"I live a pretty normal life," she says. Still, it's not everyone who can think back to the morning of October 5, when the Nobel Committee made its call.

"I got a big kick out of telling my spinning instructor I couldn't make it to class that day. I sent her a an e-mail saying, 'Sorry, can't make spinning. I just won the Nobel Prize!' "
