The “spring forward” time change is often more difficult than the “fall back” change because it means an hour less sleep. Theresa Lee, dean of the College of Arts and Sciences, says even an hour change in your routine can leave you feeling temporarily sleep deprived. And if you’re already sleep-deprived, the one hour could compound the problem.

UT Research Finds Link Between Alcohol Use, Not Pot, and Domestic Violence

Alcohol use is more likely than marijuana use to lead to violence between partners, according to studies done at UT. Research among college students found that men under the influence of alcohol are more likely to perpetrate physical, psychological, or sexual aggression against their partners than men under the influence of marijuana. Women, on the other hand, were more likely to be physically and psychologically aggressive under the influence of alcohol but were also more likely to be psychologically aggressive under the influence of marijuana.

Turns out the crocodile can be a shrewd hunter himself. A UT researcher has found that some crocodiles use lures to hunt their prey. Vladimir Dinets, a research assistant professor in the Department of Psychology, is the first to observe two crocodilian species—muggers and American alligators—using twigs and sticks to lure birds, particularly during nest-building time. Dinets’s research is the first report of tool use by any reptiles.
