Secrets of the Longest-Living Mammal Revealed

The genome of the bowhead whale was released this week by scientists who say that it may hold the key to longer and healthier lives for humans. The bowhead whale is the largest animal whose genome has been sequenced. It lives longer than any other mammal, with a lifespan of up to 200 years. Scientists studying its genome found significant differences in genes related to cell cycle, DNA repair, and aging process compared to other mammals. Although it has about 1,000 times as many cells as a human, its cells have a far more efficient anti-tumor response. More… Discuss

Paleontologists have unearthed evidence in Argentina of what may have been the largest creature ever to walk the Earth. The fossilized bones, believed to be those of a previously unknown species of herbivorous titanosaur that roamed the forests of Patagonia some 95 to 100 million years ago, suggest it was 130 ft (40 m) long from head to tail, stood 65 ft (20 m) tall, and weighed a whopping 85 tons—the equivalent of 14 African elephants.
