Chili peppers in wet areas are spicier than their dry counterparts, due to higher capsaicin levels needed to fight seed-attacking fungi. Christopher Intagliata reports
These creatures live more than five times longer than would be expected for their size. Research into the biological mechanisms underlying their longevity could suggest ideas for slowing aging in people...
An index called the longevity quotient indicates whether a species has an average life span or is unusually long-lived or short-lived for an animal of its size. A score of 1 is average; higher numbers reflect unusual longevity...
Researchers have uncovered an ancient mechanism that retards aging. Drugs that tweaked it could well postpone cancer, diabetes and other diseases of old age
