How Do We Sense Electric Fields?

A variety of animals are able to sense and react to electric fields, and living human cells will move along an electric field, for example in wound healing. Now a team lead by Min Zhao at the UC Davis Institute for Regenerative Cures has found the first actual “sensor mechanism” that allows a living cell detect an electric field.

A New Way to Fight Aging in the Brain

Our brain cells change with age: various genes become more or less active, the membrane that holds the nucleus together starts to degenerate, and molecules that in young cells are neatly compartmentalized become scattered and disorganized. Now scientists have found a way to transform ordinary skin cells into living cultures of aging human neurons—test beds for ways we might reverse these effects of time.

Dark Matter in the Universe

Could Dark Matter Cause Cancer?

But what could this dark matter possibly be? Astronomers think it must interact only very weakly with ordinary mater, otherwise we would have already seen its effects.

J. Craig Venter to Sell DNA Data to Consumers

Fifteen years ago, scientific instigator J. Craig Venter spent $100 million to race the government and sequence a human genome, which turned out to be his own. Now the entrepreneur says he will sequence the medically important genes of its clients for just $250.
