A mammalian conflict

What do a pie invented almost 2,000 years ago by the Roman statesman Cato the Elder and the organ most intimately connecting a mother and her unborn child have in common? They are both called placenta (and in some places, both are still eaten). "Placenta" comes from the Greek word plakous, meaning flat...

How life began: redux

What was the force driving the evolution of life on earth? This question, the answer to which has profound implications for our world view, was neglected for most of the 20th century, not because it was outside science, but because scientists didn't have the technical means to address it. Since the advent...

Get yourself an attitude

"Human history," said H.G. Wells, "becomes more and more a race between education and catastrophe." That was in 1920, but his words are more relevant than ever.

Finding the neurons that say: 'let's just do it'

Ever wondered why some people are full of "get up and go" and why others drag their heels? Why some kids at school charge enthusiastically around the running track, while others prefer to go for a smoke behind the bike sheds? If work published in Science this week fulfills its promise, there might soon...

We dig chimp culture

Most of what we know about ancient cultures comes from what they've left behind. Archaeology tells us, for example, about daily life in England before the Romans came and put an end to bad sanitation, and about intellectual life in Europe before the Dark Ages put an end to learning. We even know that...

We're all narrow-minded

It's a commonly held belief that we lose brain cells as we age. But, in fact, although our brains may not work as well when we get older -- learning becomes harder, memories fuzzier -- the number of cells they contain remains the same, about 28 billion. Scientists think the real problem is that the myelin...

Robo-rats galvanized into action

The invasion and colonization of Europe

Cooperation is the key to the evolution of life, even though natural selection favors genetic selfishness. Since all complex life, whether it's a tree or a whale, reproduces through sex, genes have only a 50 percent chance of getting into an egg or a sperm. This means that even genes have to cooperate,...
