Where will the water be? That is the critical question for the future as climate changes occur forcing water to change its habits. Climate change projections indicate a steady increase in temperature progressing through the 21st century, generally resulting in snow pack reductions, changes to the timing of snow melt, altered stream flows, and reductions…

One of the problems with an all electric car is charging them. As opposed to gasoline stations, there are far fewer opportunities to charge electric vehicles. Shai Agassi hopes Israel is ready to embrace the efficiency and economics of electric cars. His company Better Place rolled out four electric car charging stations in northern Israel.…

An University of California – Riverside led team has identified black carbon and tropospheric ozone as the most likely drivers of large-scale atmospheric circulation change in the Northern Hemisphere tropics zone. While stratospheric ozone depletion has already been shown to be the primary driver of the expansion of the tropics in the Southern Hemisphere, the…

Some people like food or beverages hot and some like them cold. What’s the difference? Can the temperature of the food we eat affect the intensity of its taste? It depends on the taste, according to a new study by Dr. Gary Pickering and colleagues from Brock University in Canada. Their work shows that changes…

Pain is an unpleasant feeling often caused by intense or damaging stimuli as communicated by a nerve. No one likes it though it does serve as a warning to do something about the pain source. Researchers at the University of Leeds have found a previously unknown mechanism through which pain is signaled by nerve cells.…

Cars do emit air pollutants. One aspect of this occurs during fueling of the vehicle. The U.S. Environmental Protection Agency (EPA) has determined that the systems used at gas station pumps to capture harmful gasoline vapors while refueling cars can be phased out. Modern vehicles are equipped to capture those emissions. This final rule is…

Running is a means of terrestrial locomotion allowing humans and other animals to move rapidly on foot. It is simply defined in athletics terms as a gait in which at regular points during the running cycle both feet are off the ground. This is in contrast to walking, where one foot is always in contact…

A brain-development gene found exclusively in humans has an unusual evolutionary history and could contribute to what makes us distinctly human. Equally surprising, this is a partial gene created from an incomplete duplication of its parent gene in the prehistoric human genome. The incomplete duplication of the gene may account for its behavior. This may…

The body mass index (BMI) is a heuristic proxy for human body fat based on an individual’s weight and height. BMI does not actually measure the percentage of body fat. It was devised between 1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of developing “social physics”. Body mass index is defined…

How can you make someone eat healthier? College students wishing to eat healthier may want to invest in a clear fruit bowl says a recent article published in Environment and Behavior. The new study found that when fruits and vegetables are within arm’s reach, students are more likely to eat them. Furthermore, making fruit and…
