(Oregon State University) New research provides evidence for the first time that disruption of circadian rhythms — the biological “clocks” found in many animals — can clearly cause accelerated neurodegeneration, loss of motor function and premature death.

(University of Rochester Medical Center) In a new study published in Nature Medicine, scientists discovered what they believe is one of the first drugs to combat heat stroke. AICAR – an experimental therapy once dubbed the “couch potato pill” for its ability to mimic the effects of exercise in sedentary mice – protected animals genetically predisposed to the disorder and may hold promise for the treatment of people with enhanced susceptibility to heat-induced sudden death.

(National Evolutionary Synthesis Center (NESCent)) The toothiest prehistoric predators also had beefier arm bones, finds a new fossil study. Sabertooth tigers may come to mind, but these extinct cats weren’t the only animals with fearsome fangs. Millions of years before cats came to be, multiple sabertooth predators converged on the same combination of knife-like canines and well-built arm bones. And the longer the teeth, the thicker the forelimbs, finds a new study from the National Evolutionary Synthesis Center.

(North Carolina State University) An archaeological research team from North Carolina State University, the University of Washington and University of Florida has found one of the most diverse collections of prehistoric non-native animal remains in the Caribbean, on the tiny island of Carriacou. The find contributes to our understanding of culture in the region before the arrival of Columbus, and suggests Carriacou may have been more important than previously thought.

(National Science Foundation) A study of the wolves of Yellowstone National Park recently improved predictions of how these animals will respond to environmental changes.

(University of Leeds) Scientists have discovered a mechanism they believe may play a key role in the spread of foot-and-mouth disease in animals.

(Institute of Physics) A six-legged, 25 gram robot has been fitted with flapping wings in order to gain an insight into the evolution of early birds and insects.

(Princeton University) Climate change, land use and other human-driven factors could pit savannas and forests against each other by altering the elements found by Princeton University researchers to stabilize the two. Without this harmony, the habitats, or biomes, could increasingly encroach on one other to the detriment of the people and animals that rely on them.
