By studying aging mice, scientists now believe that aging cells secrete poisons that damage surrounding cells causing age-related diseases. Removing those cells prevents disease.
What's the Latest Development?
Researchers at the Mayo Clinic in Rochester, Minnesota have taken a step toward eradicating age-related disease by better understanding how it develops. Scientists have long thought that senescent cells, which due to aging will no longer divide, cause age-related illness by simply failing to replenish tissue. But after studying a group of aging mice, and eliminating their senescent cells, scientists saw a decrease in age related illness. They now believe that senescent cells may secrete a poison which affects the healthy cells around them.
What's the Big Idea?
The experiment is being hailed as a major step forward in our understanding of the aging process. Previously it was not well understood why some diseases, like cataracts and muscle loss, naturally accompany aging. Researchers believe that if senescent cells can be removed from humans, the way they were in mice, age-related illness could be greatly reduced. As for whether removing senescent cells would prolong life, it is impossible to say. The mice in the experiment were modified to age rapidly and therefore died early from other causes.

As you vote, keep in mind that we are looking for a winner with the most engaging social venture pitch - an idea you would want to invest in.
- What distinguishes humans is social learning — and teaching.
- Crucial to learning and teaching is the value of free expression.
- And we need political leaders who support environments of social peace and cooperation.
From time-traveling billiard balls to information-destroying black holes, the world's got plenty of puzzles that are hard to wrap your head around.
- While it's one of the best on Earth, the human brain has a lot of trouble accounting for certain problems.
- We've evolved to think of reality in a very specific way, but there are plenty of paradoxes out there to suggest that reality doesn't work quite the way we think it does.
- Considering these paradoxes is a great way to come to grips with how incomplete our understanding of the universe really is.
Tragedy in art, from Ancient Greece to Breaking Bad, resists all our efforts to tie reality up in a neat bow, to draw some edifying lesson from it. Instead it confronts us with our own limitations, leaving us scrabbling in the rubble of certainty to figure out what's next.
- Why democracy has been unpopular with philosophers
- Tragedy's reminder that the past isn't finished with us
- …and why we need art in the first place
