Researchers at Stanford University have discovered a protein that contributes to skin aging. Then they developed a lotion that counters the protein. Then they genetically engineered a mouse to respond to the treatment. After two weeks, the skin of test mice was nice and smooth again.

Still, seems like an awful lot of trouble to go through for younger-looking mice.

I'm recommending this New York Times article about turtles and their amazing abilities to withstand adversity. They can go without food and water for months at a time, their armored bodies can withstand the impact of a stampeding wildebeast, and they're among the longest-living creatures on Earth. And they don't succumb to old age: if they didn't get eaten, smashed by cars, or pick up diseases, they just might live indefinitely. But for all that, at least half of all turtle species are in trouble, and some of them may be extinct within the next decade.

Want to live 200 years?

Scientists have found a small molecule that can be used to extend the lifespan of mammalian cells. The research reported in the July issue of Nature Chemical Biology showed that the synthetic organic molecule CGK733 blocks the machinery that senses DNA damage. They found that CGK733 could extend the lifetime of cultured cells by about 20 doublings and could actually rescue cells that were already senescent. Senescent cells are cells that can stay alive but have stopped dividing.

Magnetic nano probe used to see drug interactions inside living cells

Prof. Kim Tae-kook at the Korea Advanced Institute of Science and Technology and his associates developed a technology dubbed MAGIC, short for magnetism-based interactive capture. This state-of-the-art magnetic nano-probe technology uses fluorescent materials to check whether any drug can mix with targeted proteins inside the cell.
