Solving the Peto Paradox

Elephants, despite their size and long lifespan, get cancer less often than smaller species. This paradox was named after Richard Peto, a British epidemiologist from Oxford, who noticed it back in the 1970s.

How Epigenetic Heredity works

The mice conceived with the help of spermatozoa completely cleared of epigenetic marks almost universally suffered from the most serious developmental defects, anomalies in the structure of the skeleton, and many of them did not even live to be born.

238 genes that yeast lives longer without

Almost half of these genes that affect life expectancy are also found in mammalian DNA. In theory, all these DNA sites can be the "targets" that can be hit by life-prolonging drugs.
