Charles Darwin proven right on natural selection

The famous scientist would be pleased because a study published online this week provides the first clear evidence that natural selection, his favored mechanism of evolution, drives the process of species formation in a wide variety of plants and animals.

Using neural growth factor could allow researchers to mass produce stem cells for treatment of disease

Human embryonic stem cells (hES) offer great hope for the treatment of some devastating diseases, but finding a way to keep enough of these cells usable and healthy for transplantation in patients has been an ongoing problem.

Mystery of evolutionary growth in hominid brain size

Forget the textbook story about tool use and language sparking the dramatic evolutionary growth of the human brain. Instead, imagine ancient hominid children chasing frogs. Not for fun, but for food.

Science is bypassing poor people

Applying science and technology to build a Pluto-bound spacecraft that travels more than 10 times faster -- 47,000 miles per hour -- than a speeding bullet is a great achievement. But can we apply technology to feed the 800 million hungry people in the world whose plight isn't improving in a modern world?
