Nobel goes to gene-knockouts

A technology that revolutionized medicine and genetics gets the big Nobelian Nod. Cancer. Heart disease. Obesity. Research into virtually every major disease has gotten a boost from the Knockout Nobel! More »

Study finds key to colony-collapse disorder

Fast genomic analysis could open the door to breakthroughs in health, ecology and genetics. How do these machines work, and what have they taught about obesity, microbial diversity, and drug treatment? More »

Breeding dogs, breeding other animals

Football star convicted for bloody dog-fighting operation. What made the wolf turn into 400+ breeds of dog? How have farmers and animal breeders changed cattle and chickens? Why bother saving an old breed of horse? More »

Biodiversity: Species Form Faster Near Poles

Conventional wisdom says species form faster in the biodiverse tropics. But a new study shows fast speciation and extinction at the poles. Why didn’t we think up this study?
