To Defeat A Deadly Toxin, Disrupt Its Landing Gear

A high-resolution image of the molecular carrier that moves the botulinum toxin from the intestine into the bloodstream. The carrier (silver) creates gaps in the gut lining by grabbing the rope-like molecules (red ribbons) that tether one intestinal cell to the next.

Botulinum toxin may be the most poisonous substance on the planet. A mere speck of the stuff can kill a person.

But just what makes the toxin so potent?

Part of the answer lies in the molecules that carry the toxin through the body. These carriers, which are produced along with the toxin by the Clostridium botulinum bacterium, protect the toxin as it travels through the hostile environment of the gastroinstetinal tract, and help it bust through the intestinal wall and into the bloodstream.

How To Become A Neanderthal: Chew Before Thinking

By comparing "Skull 17" from the Sima de los Huesos site with many others found in the same cave, researchers were able to discern the common facial features of the era.

Scientists have long puzzled over the origin and evolution of our closest relative, the Neanderthal. Now, researchers say Neanderthals seem to have developed their distinctive jaws and other facial features first, before they evolved to have big brains.

That's according to an analysis of 17 skulls, all taken from one excavation site in a mountain cave in Atapuerca, Spain, known as the Sima de los Huesos — the "pit of bones."
