Scientists have completed the first assessments of how readily the H7N9 flu virus in China can pass among ferrets and pigs. The mammals provide the best inkling of how dangerous these bugs may become for humans.

The news is both bad and good. They've found the new bird virus is easily passed between ferrets sharing the same cage.

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?

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.
