Do humans hear better than animals? It is known that various species of land and water-based living creatures are capable of hearing some lower and higher frequencies than humans are capable of detecting. However, scientists have now for the first time demonstrated how the reactions of single neurons give humans the capability of detecting fine differences in frequencies better than animals.
The simple act of running in an exercise wheel delays the onset of some symptoms of Huntington's disease in a mouse model of the fatal human disorder according to new research. These findings add insights into the pathogenesis of the disease and suggest possible preventive therapeutic targets.
Nine out of ten food advertisements shown during Saturday morning children's television programming are for foods of poor nutritional quality, according to researchers. During a sample of 27.5 hours of shows aimed at pre-school and elementary school-aged children, 91 percent of food ads were for foods or beverages high in fat, sodium or added sugars or were low in nutrients, according to the study.
Deep in the bowels of the earth -- 100 meters below ground in Geneva, Switzerland -- lies a supermachine of 27 kilometers circumference that has been built to unlock the mysteries of the universe. 2,500 scientists from 37 countries were recruited to help design, test the supermachine that will provide a new perspective into what occurred at the time of the Big Bang.
As gas prices continue to soar to record highs, motorists are crying out for an alternative that won't cramp their pocketbooks. Scientists are answering that call by working to chemically manipulate algae for production of the next generation of renewable fuels -- hydrogen gas.
The geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. Continents lose more than 20 percent of their initial mass to chemical weathering, but they ultimately gain because the lighter, silicon-rich rock that's left behind is more buoyant and less prone to being subducted and returned to the mantle.
Could part of the answer to saving the Earth from global warming lie in the earth beneath our feet? For the first time, researchers aim to design soils that can remove carbon from the atmosphere, permanently and cost-effectively.
One group of small, non-coding RNA molecules could serve as a marker to improve cancer staging and may also be able to convert some advanced tumors to more treatable stages.
New research suggests that college-age men confuse friendly nonverbal cues with cues for sexual interest because the men have a less discerning eye than women -- but their female peers aren't far behind. Men who viewed images of friendly women misidentified 12 percent of the images as sexually interested. Women mistook 8.7 percent of the friendly images for sexual interest.
Scientists find predisposition for skinny jeans is in the genes. Your friend can eat whatever she wants and still fit into her prom dress, but you gain five pounds if you just look at that chocolate cake. Before you sign up for Weight Watchers and that gym membership, though, you may want to look at some recent research and save yourself a few hundred dollars. A woman's waistline may have less to do with rigorous exercise and abstaining from sweets than it does with the genes of her parents.
