In-car air study of commuting cars finds dangers to human health — ScienceDaily

The first in-car measurements of exposure to pollutants that cause oxidative stress during rush hour commutes has turned up potentially alarming results. The levels of some forms of harmful particulate matter inside car cabins was found to be twice as high as previously believed. Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period. Exhaust composition, however, changes rapidly enough for drivers to experience different conditions inside their vehicles than…

From legal means like hiring the best trainers and purchasing the best equipment, to less legal means like pharmaceutical enhancement, athletic advantages come in all forms. But…

UCI-led analysis of data from India could have dire implications for future — ScienceDaily

An increase in mean temperature of 0.5 degrees Celsius over half a century may not seem all that serious, but it’s enough to have more than doubled the probability of a heat wave killing in excess of 100 people in India, according to researchers at the University of California, Irvine and other institutions. This could have grim implications for the future, because mean temperatures are projected to rise by 2.2 to 5.5 degrees Celsius by the end of this century…
