Just 10 minutes of exercise can trigger powerful anti-cancer effects

Just 10 minutes of intense exercise can flip genetic switches that help stop bowel cancer in its tracks. Credit: Shutterstock As people return to gyms or start new fitness routines in the new year, new research suggests that even a short burst of intense exercise could play a role in protecting against cancer. Scientists report that as little as 10 minutes of hard physical activity may help slow cancer growth.

Bowhead whales can live for more than 200 years - this protein might be why

A cold-induced RNA-binding protein enhances double-strand DNA-break repair and may underlie bowhead whales' extreme lifespan, with effects seen in flies and human cells.

Chinese scientists discover the DNA secret behind the naked mole-rat's astonishing longevity

There is an iron law in nature: the larger a species, the longer its members live. That's why whales outlive elephants, and elephants outlive lions. Very few animals defy this rule. Humans have circumvented it thanks to culture. But there is a small animal that laughs in its face. Given its size, the naked mole-rat (Heterocephalus glaber) shouldn't live more than two years, yet they often approach 40. What's more, they age healthily, without typical age-related diseases such as cancer, neurodegenerative disorders, or arthritis.
