For those who have always wanted to see David Hasselhoff's house, Lifetime has a series for you. In conjunction with Beverly Hills-based Julien's Auctions, the network will debut "Celebrity Home Raiders" on Thursday at 10 p.m. The premise couldn't be simpler: Stars put personal belongings up for sale, with proceeds going to the charity of their choosing. Here's the twist: While the host, Kit Hoover from "Access Hollywood," gets the celebrities to put a dollar value on their memorabilia, Julien's co-owners Darren Julien and Martin Nolan roam through the residence looking for goodies.

The manipulation of human genes could lead to profound advances in our ability to cure or prevent terrible diseases. But in some cases, it might also mean introducing genetic material that could be passed from one generation to the next, changing the human gene pool in a manner that could inadvertently harm peoples' health. Such "inheritable" DNA is a hotly debated issue among bioethicists, and one that an advisory committee of the Food and Drug Administration will review Tuesday and Wednesday as it considers whether human trials should be allowed for a new therapy that could prevent a rare but devastating inherited disorder.

Mating between Neanderthals and the ancestors of Europeans and East Asians gave our forebears important evolutionary advantages but may have created a lot of sterile males, wiping out much of that primitive DNA, new genetic studies suggest. The comparison of Neanderthal and modern human genomes, published online Wednesday in the journals Nature and Science , identified specific sequences of altered DNA that both Neanderthals and several...

The ancestors of most modern humans mated with Neanderthals and made off with important swaths of DNA that helped them adapt to new environments, scientists reported Wednesday. Some of the genes gained from these trysts linger in people of European and East Asian descent, though many others were wiped out by natural selection, according to reports published simultaneously by the journals Nature and Science. The stretches of Neanderthal DNA that remain include genes that altered hair and pigment, as well as others that strengthened the immune system, the scientists wrote.

Fish don't have fingers, but they could. That conclusion, drawn by a team of researchers in Switzerland, casts new light on the evolution of four-legged land vertebrates, suggesting that a flick of a switch could have repurposed the bony radials of fins to become the fingers and toes of land-based animals. The DNA programming architecture necessary to create such digits was present in the ancient genome of fish, before the emergence of amphibians, according to the researchers, who published their findings Tuesday in the online journal PLOS Biology.

Do genes make us do it? The idea that human behavior is driven by genes makes many people uncomfortable, and nowhere is the dispute more bitter than when discussing the biological underpinnings of violence. The war of ideas over violence and human nature has raged since the 1600s, when philosopher Thomas Hobbes first speculated that the "natural condition of mankind" was one of violence and conflict. In the 1700s, Jean-Jacques Rousseau saw things differently. Enthralled with accounts of the New World, he argued that civilization, not nature, shaped the human propensity for violence.
