Vision researchers have disproved a long-standing theory of how the human vision system processes images, using computational models and human experiments. The findings could have implications for the understanding of human vision and diagnosis of vision anomalies.
Read morePeople who carry around unhealthy amounts of weight don't just have heart disease and diabetes to worry about. Obesity is implicated in two thirds of the leading causes of death from non-communicable diseases worldwide and the risk of certain diseases differs for men and women.
Read moreResearchers have identified a potential approach to stop the growth of the most common type of brain tumor in children.
Read moreMammalian brains, with their unmatched number of nerve cells and density of communication, are the most complex networks known. While methods to analyze neuronal networks sparsely have been available for decades, the dense mapping of neuronal circuits is a major scientific challenge. Researchers have now succeeded in the dense connectomic mapping of brain tissue from the cerebral cortex, and quantify the possible imprint of learning in the circuit.
Read moreIn any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide.
Read moreA new study uncovered new information on why the Ebola virus can exert such catastrophic effects on the infected person. They've described for the first time how the virus disables T cells, an important line of immune defense, thus rendering the infected person less able to combat the infection.
Read moreLaryngeal paralysis is a serious and sometimes deadly disease in some dog breeds that prevents proper opening of the larynx for breathing. Specialists in canine head and neck surgery and geneticists have identify a mutation responsible for laryngeal paralysis in Miniature Bull Terriers, enabling the development of a genetic test for the disease.
Read moreA multicenter randomized clinical trial evaluating a new artificial pancreas system — which automatically monitors and regulates blood glucose levels — has found that the new system was more effective than existing treatments at controlling blood glucose levels in people with type 1 diabetes.
Read moreResearchers have identified several chemical signatures, detectable in blood and urine, that can accurately measure dietary intake, potentially offering a new tool for physicians, dieticians and researchers to assess eating habits, measure the value of fad diets and develop health policies.
Read moreTypical geologic investigations of active earthquake fault zones require that the fault can be observed at or near the Earth's surface. However, in urban areas, where faults present a direct hazard to dense populations, the surface expression of a fault is often hidden by development of buildings and infrastructure. This is the case in San Diego, California, where the Rose Canyon fault zone trends through the highly developed downtown.
