How Did Whales Evolve to Beat Cancer?

Unpicking the Whale Genome to Uncover How They Evolved to Beat Cancer

Whales, which live longer than most mammals on the planet and have a much higher percentage of body fat, should be more likely to develop cancer. Yet their cancer rates are remarkably low. This phenomenon, known as Peto's Paradox, is investigated in a new study and may provide tantalizing clues for addressing the disease in humans.

For the First Time, Astronauts Edit Genes in Space


For the first time, astronauts have used CRISPR/Cas9 technology to edit DNA in space. The gene editing technique was deployed on the International Space Station (ISS) to induce targeted breaks in the yeast genome.


Animal Study Cautions Against Overeating Omega-6 Fats in Pregnancy


In Western societies, we are eating more omega 6 fats. A research study using rat models showed that eating a diet with three times the recommended daily intake of linoleic acid might be harmful in pregnancy.


Flawed Genome for Widely Researched Worm Is Corrected


A new study finds that the genome for a widely researched worm, on which countless studies are based, was flawed. Now, a fresh genome sequence will set the record straight and improve the accuracy of future research.
