SCIENCE: There Are (At Least) Four Distinct Patterns of Aging

Some people’s hearts stay strong well into their 60s, but their kidneys begin to fail. Others may have the kidneys of a 30-year-old but fall victim to constant infection. Now, scientists may be one step closer to understanding why the aging process varies so drastically between people. Even within a single person, aging unfolds at different rates in different tissues, sometimes striking the liver before the heart or kidney, for example. People fall into distinct categories depending on which of their biological systems ages fastest, and someday, doctors could use this information to recommend specific lifestyle changes and design personalized … Read more

SCIENCE: Scientists Find Young Cells in Old Brains

Your brain keeps making new nerve cells, even as you get older. That’s a big deal. For decades, researchers believed that aging brains stop making new cells. But recent research has offered strong evidence to the contrary, and a new paper published today (April 5) in the journal Cell Stem Cell tries to put the notion to bed entirely. Aging brains, the researchers showed, produce just as many new cells as younger brains do. “When I went to medical school, they used to teach us that the brain stops making new cells,” said lead study author Dr. Maura Boldrini, a … Read more

SCIENCE: Real Life Vampires

Ben Franklin famously wrote: “In this world, nothing can be said to be certain, except death and taxes.” What he didn’t mention, despite being 83 years old, was a third, almost inevitable eventuality: ageing. Depending on when in history and where on the planet you look, ageing is variously considered desirable – bringing with it wisdom and status – or as something to be feared, eliminated, or at least delayed as long as possible. In the 16th to 18th centuries, Western societies believed old age was a time of considerable worth. But, since the 19th century, we have sought ways … Read more

The Oldest Living Creature on Earth?

Chinese scientists say they have discovered a nearly 5-foot-long Giant Salamander in a cave in southwestern China which may be close to 200 years old, which would make it the oldest living creature on Earth (besting a tortoise, which is said to be 183). The creature, a species which is critically endangered, was transferred to a facility for observation. It’s unclear what affect removal from its natural habitat may have on its health, but our guess is not great. By Andy Towle – Full Story at
