Some experts dismiss all studies of Internet use as flawed, since there is no reasonable way to control for the myriad variables that may affect such research. For its part, Facebook declined to address the specific findings of the new study but issued a statement on Monday, April 13, saying that Facebook isn't the only diversion around; TV and video games can be just as distracting as online social networks. The company also pointed to a study released earlier this month by researchers at the University of Melbourne showing that personal Internet use at work can help focus workers...
...easy to kill a full-grown tree - especially one like the piñon pine. The hardy evergreen is adapted to life in the hot, parched American Southwest, so it takes more than a little dry spell to affect it. In fact, it requires a once-in-a-century event like the extended drought of the 1950s, which scientists now believe led to widespread tree mortality in the Four Corners area of Utah, Colorado, New Mexico and Arizona...
...isolate the specific impact of temperature on tree mortality during drought - and it indicates that in a warmer world trees are likely to be significantly more vulnerable to the threat of drought than they are today. "This raises some fundamental questions about how climate change is going to affect forests," says David Breshears, a professor at UA's School of Natural Resources and a co-author of the PNAS paper. "The potential for lots of forest die-off is really there...
...Since the days of Freud, research into the mind-body relationship has come a long way. Studies show that not only are your mental health and mood dependent in large part on physical factors like exercise, but also unchecked stress, anxiety and depression can affect physical health, increasing blood pressure, heart disease and even risk of death. So it was perhaps inevitable that patients would start bringing their yoga mats into therapy...
...Other sports physiologists are currently studying how ingesting the sugared solution, as opposed to just rinsing with it, affects physical performance, and how the body responds to artificially sweetened drinks. The body may undergo a kind of metabolic letdown in anticipation of a sugar rush that never comes, which could affect performance. "In some ways, the body's reaction is to the 'promise' of an incoming carbohydrate load, so one wonders what happens when that promise is not fulfilled," says Williams...
