The Life and Times of Domesticated Cheese-Making Fungi

Sep. 24, 2015 — People sure love their cheeses, but scientists have a lot to learn about the fungi responsible for a blue cheese like Roquefort or a soft Camembert. Now researchers have pieced together the story of ... read more

Sep. 24, 2015 — Mitochondria are not only the power plants of our cells; these tiny structures also play a central role in our physiology. By enabling flexible responses to new environments, mitochondria have helped ... read more

Sep. 22, 2015 — Scientists have found that the gut microbiome of right whales and other baleen species shares characteristics with both cows and meat-eating predators. The dual microbial communities allow whales to ... read more
