Men from early middle ages were nearly as tall as modern people
...-term trend of cooler temperatures, so people were less
likely to move to warmer regions and were more likely to stick with traditional farming methods that ultimately failed," he said. "Climate change was likely to have imposed serious economic and health costs on northern Europeans, which in turn may ha...
Veterinarians discover first known case of canine distemper in a wild tiger
... heroic efforts to save her, the tiger died. "With less
than 500 Siberian tigers left in the wilds of Russia, this is a very serious threat that could contribute to the loss of this severely endangered population," said Dr. Quigley. In 1994 canine distemper virus killed a third of the lions in the Serenge...
Chernobyl study: Risk of thyroid cancer rises with radiation dose
... identified 26 people with thyroid cancer who were less
than 20 years old when the Chernobyl accident occurred; the majority were under 16 when their thyroid cancers were diagnosed. They then identified 52 healthy control subjects from the general population for comparison purposes. The controls and cance...
DHA-rich diet protects brain from Alzheimer's damage, UCLA study shows

Convulsions in worms mimic epileptic seizures
...to the end of the cell, GABA neurons might release less
neurotransmitter and therefore not fire properly. That, in turn, could lower the worms' convulsion threshold. "Neurons are still just cells," said Caldwell. "Trafficking defects may manifest themselves in different ways in different cell types, and ...
University of Arizona licenses patent for natural fungicide
...rhamnolipid, because of its biological nature, has less
toxicity and better biodegradability," said Raina M. Maier, a professor in UA's department of soil, water and environmental science who is one of the inventors. Other inventors listed on the patent are Michael E. Stanghellini, UA professor emeritus o...
Probing the surface of white blood cells to enhance immune system medicine
...at eliminate lymphocyte microvilli could lead to a less
toxic form of immune suppression for transplant recipients. Since many cancer cells share the same mechanism of extravasation as lymphocytes, ablating microvilli could also prevent metastasis of cancer cells to distant parts of the body. Similarly, b...
Diabetics face fewer healthy food choices in some urban areas
...Side grocery stores. The Harlem stores were much less
likely to stock healthy food choices such as whole-grain breads and diet soda. The researchers surveyed five specific foods recommended for diabetics: diet soda, one percent fat or fat-free milk, high-fiber and/or low-carbohydrate bread, fresh fruit...
