U.S. pathologists say they've found a biochemical pathway that protects cells in low oxygen can also create a longer life with fewer degenerative diseases. University of Washington Assistant Professor Matt Kaeberlein and colleagues found nematode worms live longer if their genetic makeup permits their cells to turn on a protective reaction to a drop in oxygen -- a reaction called the hypoxic response -- even under normal oxygen conditions. Not only do the worms live longer, the researchers...

Researchers at the University of Washington have found a genetic pathway linking nutrient response and the aging process, they report in the Nov. 18 issue of the journal Science. Scientists have long known that dramatically reducing food intake boosts the lifespan of model organisms such as mice, but the new results point to a possible mechanism through which drastic calorie restriction affects aging. As scientists learn more about the biochemical processes that affect lifespan, they might...

omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
