Ebola Vaccine Desperately Needed for Chimps, Gorillas

January 20, 2015 3:00 pm | by The Conversation, Meera Inglis | News | Comments

At this moment in time, Ebola is the single greatest threat to the survival of gorillas and chimpanzees. The virus is even more deadly for other great apes than it is for humans, with mortality rates approximately 95 percent for gorillas and 77 percent for chimpanzees. Current estimates suggest a third of the world’s gorillas and chimpanzees have died from Ebola since the 1990s.

Snail Produces Weaponized Insulin

January 20, 2015 7:00 am | by Univ. of Utah | News | Comments

As predators go, cone snails are slow-moving and lack the typical fighting parts. They’ve made up for it by producing a vast array of fast-acting toxins that target the nervous systems of prey. And, a new study reveals that some cone snails add a weaponized form of insulin to the venom cocktail they use to disable fish.

Researchers Study Quasars in the Early Universe

January 19, 2015 7:00 am | by Univ. of Cambridge | News | Comments

Two teams of astronomers have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars— extremely luminous objects powered by supermassive black holes— regulate the formation of stars and the build-up of the most massive galaxies. They found that a quasar spits out cold gas at speeds up to 2,000 kilometers per second, and across distances of nearly 200,000 light years.
