Seeing Double: Errors In Stem-Cell Cloning Paper Raise Doubts
Biologists said last week that they had overcome a major obstacle in stem-cell research by cloning human embryos. But several images in the published study were duplicated and labeled incorrectly, prompting questions about the authenticity of the results.
Scientific Tooth Fairies Investigate Neanderthal Breast-Feeding
Our closest relatives, chimpanzees and gorillas, breast-feed their offspring for several years. Some baby orangutans nurse until they are 7 years old. Researchers found a way to test ancient teeth for clues about when humans cut nursing short.

Could African Crops Be Improved With Private Biotech Data?
A plant scientist at Mars Inc. has appealed to the world's biggest life sciences companies to help him — by sharing what they already know about 100 crops that could provide better nutrition in Africa. But can the kings of agricultural intellectual property get onboard with open source agricultural information for Africa?

The First Web Page, Amazingly, Is Lost
Ironically, there's one piece of Web history that can't be found online: the very first page. Now, a team at the lab where the World Wide Web was born is on a hunt for old hard drives and floppy disks that might hold copies of the missing files.
Research Reveals Yeasty Beasts Living On Our Skin
While studying microorganisms on humans is not new, tracking fungi is. In a census of sorts, scientists checked the skin of healthy volunteers. They found an expansive ecosystem of silent inhabitants.
How Benjamin Franklin Invented A Weight Loss Program, Using Balloons
"Someone asked me," Benjamin Franklin once said, "what's the use of a balloon?" They don't do much. They just float. What are they good for? And Franklin replied, "What's the use of a new-born baby?" They just sit there. They don't do much. You have to imagine possibilities. This is Franklin, in the 1780s, thinking about balloons.
How Genomics Solved The Mystery Of Ireland's Great Famine
Although scientists have known that a funguslike organism caused the potato blight that triggered the Great Famine in Ireland in the 1840s, they didn't know which strain was the culprit. But they do now, thanks to the genes in some 19th century potato samples.
Quantum Or Not, New Supercomputer Is Certainly Something Else
NASA and Google have come together to buy a new kind of computer that the manufacturer says runs on the strange laws of quantum mechanics. But some physicists counter that the machine, known as the D-Wave Two, has never demonstrated a phenomenon known as "quantum entanglement."
Storm Chasers Seek Thrills, But Also Chance To Warn Others
When disaster strikes, our natural instinct is to take cover and seek shelter. But in severe weather, especially the type that breeds tornadoes like we saw in Oklahoma and parts of the Midwest this week, there are those who ride toward the storm.
Vertical 'Pinkhouses:' The Future Of Urban Farming?
Architects have come up with spectacular concepts for vertical farms that would grow crops in city skyscrapers. But many horticulturists think the future of vertical farming isn't in skyscrapers, but rather in large, indoor warehouses lit up magenta by superefficient LEDs.

Storm Chasers In It For The Thrill, Chance To Warn Others
Melissa Block talks with Chris McBee, a storm chaser and native Oklahoman who shot video of Monday's tornado, as it tore through the area around Oklahoma City. McBee and his companions phoned in the funnel cloud's location to the National Weather Service moments before debris — splintered wood and insulation — came whipping through the air.
'Nanogardens' Sprout Up On The Surface Of A Penny
Engineers have figured out a way to get crystals to form rose and tulip sculptures, each smaller than a strand of hair. The gardens sprout up on a penny dipped in a salt solution. The technique is similar to 3-D printing and could one day be used to make any complex shape.
Forecasters Had Chance To Warn Moore, Okla., Before Tornado
Melissa Block talks to Jon Hamilton about the science of tornadoes.
Measuring The Power Of Deadly Tornadoes
Tornado strength is currently measured on what is called the Enhanced Fujita Scale, which gives the tornado a rating from 0 to 5 based on estimated wind speeds and the severity of the damage.
The Little Metronome That Wouldn't
Take a metronome. Then take another. Then another. Set them ticking at different times. Look. Lift. (That's the key part.) Watch. Then Laugh. Because you will be dumbfounded.
Can A Piece Of Hair Reveal How Much Coke Or Pepsi You Drink?
People are notorious for under-reporting what they consume — they lie, forget or just guess wrong. For researchers who want to know how much soda we're drinking, a high-tech analysis technique could help.

If Your Shrink Is A Bot, How Do You Respond?
A computer-simulated woman named Ellie is designed to talk to people who are struggling emotionally and take their measure — 30 times per second. Researchers hope their technology, which reads a person's body language and inflections, will yield diagnostic clues for clinical therapists.

Bans Of Same-Sex Marriage Can Take A Psychological Toll
When several states passed laws banning same-sex marriages, researchers found that the mental health of gay residents seemed to suffer. Conversely, stress-related disorders dropped after the legalization of gay marriage in one state. Researchers say negative media portrayals and loss of safety were contributing factors.
