Stuart Kim, PhD, Stanford University professor of developmental biology and genetics Prevailing theory of aging challenged by Stanford University Medical School researchers. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage similar to rust. The Stanford findings suggest specific genetic instructions drive the process. If they are right, science might one day find ways of switching the signals off and halting or even reversing aging.

Can we tweak certain genes to stave off the aging process—or, conversely, to speed it up? New research indicates that it may one day be possible.

The De Grey Technology Review controversy was a debate over the validity of the ideas of Aubrey de Grey, published in MIT's Technology Review.

The stated goal of the SENS Challenge was to demonstrate that "SENS is so wrong that it is unworthy of learned debate." Whether or not this was accomplished by a given submission was to be determined by a panel of judges, and the final judges were self-selected from a large pool of people offered positions on the panel. Persons with relevant expertise were not included in the final panel of judges, leaving only those who know little or nothing of the existing learned debate within gerontology and life extension research. We have long objected to these and other aspects related to the judging of this challenge, and they have given us little confidence in its overall structure.

Aubrey de Grey thinks he knows how to defeat aging. He's brilliant, but is he nuts?

Older Brain Really May Be a Wiser Brain

The Presidency really takes its toll; just look at how George Bush has aged. To see how the current candidates would fare after a term in the Oval Office, we put them through the Pop Photo Time Machine. See our Photoshopped before and afters of Hillary Clinton, John McCain, and Barack Obama.

The gurus at PopPhoto have digitally altered photos of John McCain, Barack Obama, and Hillary Clinton to show how they might look after four years of holding the most stressful job in the country.
