For every $1 invested in a Chicago early childhood education program, nearly $11 is projected to return to society over the children's lifetimes -- equivalent to an 18 percent annual return on program investment, according to a study led by University of Minnesota professor of child development Arthur Reynolds in the College of Education and Human Development.

A little disorder goes a long way, especially when it comes to harnessing the sun's energy. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) jumbled the atomic structure of the surface layer of titanium dioxide nanocrystals, creating a catalyst that is both long lasting and more efficient than all other materials in using the sun's energy to extract hydrogen from water.

(Santa Barbara, Calif.) –– The increased frequency of drought observed in Eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to UC Santa Barbara scientist Park Williams.

The increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics.

This poses increased risk to the estimated 17.5 million people in the Greater Horn of Africa who currently face potential food shortages.

Disasters—both natural and manmade—can strike anywhere and they often hit without warning, so they can be difficult to prepare for. But what happens afterward? How do people cope following disasters? In a new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, George Bonanno, Chris R. Brewin, Krzysztof Kaniasty, and Annette M. La Greca review the psychological effects of disasters and why some individuals have a harder time recovering than do others.

The temperatures of North Atlantic Ocean water flowing north into the Arctic Ocean adjacent to Greenland -- the warmest water in at least 2,000 years -- are likely related to the amplification of global warming in the Arctic, says a new international study involving the University of Colorado Boulder.

Researchers at the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital examined running-related injuries among children and adolescents 6 to 18 years old and found that an estimated 225,344 cases were treated in U.S. emergency departments from 1994 through 2007, for an average of more than 16,000 each year. During the 14-year study period, the annual number of running-related injuries increased 34 percent.
