The study, published ... Read More

An ancient killer: Ancestral malarial organisms traced to age of dinosaurs

CORVALLIS, Ore. - A new analysis of the prehistoric origin of malaria suggests that it evolved in insects at least 100 million years ago, and the first vertebrate hosts of this disease were probably reptiles, which at that time would have included the dinosaurs. Read More

High protein diet could reduce obesity in dogs

“There are many gut microbiome studies on humans and rodents, but not a whole lot on dogs, in particular,” says Johnny Li, a computational biologist at the Nestle Purina PetCare Company, in St. Louis.

Neanderthals may have been infected by diseases carried out of Africa by humans

A new study suggests that Neanderthals across Europe may well have been infected with diseases carried out of Africa by waves of anatomically modern humans, or Homo sapiens. As both were species of hominin, it would have been easier for pathogens to jump populations, say researchers. This might ... Read More
