Seeing Double: Errors In Stem-Cell Cloning Paper Raise Doubts

Biologist Shoukhrat Mitalipov stands outside the monkey enclosure at his lab in Oregon. He says the mistakes in his recent paper were caused by the rush to publish quickly.

This feels a bit like deja vu.

Scientists report a major breakthrough in human stem-cell research. And then just a week later, the findings come under fire.

Biologists at Oregon Health & Science University said May 15 that they had cloned human embryos from a person's skin cell.

When it comes to weaning, humans are weird.

Our closest relatives, chimpanzees and gorillas, breast-feed their offspring for several years. Some baby orangutans nurse until they are 7 years old.

But modern humans wean much earlier. In preindustrial societies, babies stop nursing after about two years. Which raises the question: How did we get that way? When did we make the evolutionary shift from apelike parenting to the short breast-feeding period of humans?

The First Web Page, Amazingly, Is Lost

This computer was the first Web server. It was used by Tim Berners-Lee in 1990 to develop and run the first multimedia browser and Web editor.

Given the World Wide Web's ubiquity, you might be tempted to believe that everything is online. But there's one important piece of the Web's own history that can't be found through a search engine: the very first Web page.

Now a team at the lab where the World Wide Web was invented is seeking to restore that page, and other pieces of memorabilia from the earliest moments of the http:// era. They're on the hunt for old hard drives and floppy disks that may hold missing copies of early, valuable files.

"I'm shocked by the optimism here," Howard Yana-Shapiro, the chief agricultural officer for Mars Inc. said Tuesday to the audience of the Chicago Council on Global Affairs' Global Food Security Symposium in Washington, D.C.

Seated there before him were some of the leaders from the wealthiest international organizations and multinational companies of the fight to end hunger. And Shapiro told them they weren't even close.

Research Reveals Yeasty Beasts Living On Our Skin

Fungi (cyan) surround a human hair within the skin. A study in the journal Nature shows the population of fungi on human skin is more diverse that previously thought.

Scientists have completed an unusual survey: a census of the fungi that inhabit different places on our skin. It's part of a big scientific push to better understand the microbes that live in and on our bodies.

"This is the first study of our fungi, which are yeast and other molds that live on the human body," says Julie Segre, of the National Human Genome Research Institute, who led the survey.
