Scientific Tooth Fairies Investigate Neanderthal Breast-Feeding

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?

"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.

The First Web Page, Amazingly, Is Lost

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.

Research Reveals Yeasty Beasts Living On Our Skin

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.

Trillions of microbes live everywhere in and on our bodies. Most of these viruses, bacteria and other microorganisms are harmless.

The Inevitable Question?

Last week I gave a lecture at a corporative event for some 200 executives in the insurance business. Although this happened abroad, my experience is that things would not have been very different here.

An international group of plant pathologists has solved a historical mystery behind Ireland's Great Famine.

Sure, scientists have known for a while that a funguslike organism called Phytophthora infestans was responsible for the potato blight that plagued Ireland starting in the 1840s.

Quantum Or Not, New Supercomputer Is Certainly Something Else

It's exactly the sort of futuristic thinking you'd expect from Google and NASA: Late last week, the organizations announced a partnership to build a Quantum Artificial Intelligence Lab at NASA's Ames Research Center.

But questions surround the new type of computer at the lab's core. D-Wave systems, the company that makes the machine, says it is a quantum computer — a machine that runs on the strange laws of quantum mechanics.

Vertical 'Pinkhouses:' The Future Of Urban Farming?

Michaeleen Doucleff — Tue, 21 May 2013 20:01:00 +0000

The idea of vertical farming is all the rage right now. Architects and engineers have come up with spectacular concepts for lofty buildings that could function as urban food centers of the future.

In Sweden, for example, they're planning a 177-foot skyscraper to farm leafy greens at the edge of each floor.
