CHAMPAIGN, Ill. -- A new study finds that pre-adolescent children who have sustained sports-related concussions have impaired brain function two years following injury.

The results are published in the International Journal of Psychophysiology.

Over a million brain injuries are treated annually in the U.S. While organized sports at all levels have implemented safety protocols for preventing and treating head injuries, most pediatric concussions still result from athletic activities.

Climate change is rapidly heating up lakes around the world, threatening freshwater supplies and ecosystems across the planet, according to a study spanning six continents.

More than 60 scientists took part in the research, published in the journal Geophysical Research Letters and announced today at the fall meeting of the American Geophysical Union.

ST. LOUIS -- A Saint Louis University public health researcher is proposing immediate, concrete steps to stem police shootings of black males.

Keon Gilbert, DrPH, assistant professor of behavioral science and health education at Saint Louis University's College for Public Health and Social Justice, outlined his recommendations in an academic paper published Dec. 10, 2015 in the online edition of the Journal of Urban Health.

With the holiday season at a fever pitch and charitable giving on people's minds, new research from the University of Delaware suggests that for organizations interested in increasing the number of givers and the amount of donations, the solution might be as easy as a simple change in how charitable gifts are made.

For the past three years, as part of their course requirements, 190 of Kent Messer's undergraduate students have attended a guest lecture presented by Kate Hackett, executive director of Delaware Wild Lands (DWL).

One thing that prevents cost-effective uptake of large-scale alternative energy, like solar and wind energy, is a lack of storage solutions. On the small scale, it is only an annoyance that battery technology has not really advanced in decades.

One thing that may help on the small scale is understanding how existing disposable Lithium batteries degrade during normal use, following on a study showing how they fail at high heat. The study follows calls from investigators in August 2015 for a safety review of all lithium battery-powered equipment on planes after a fire on board a grounded Boeing 787 Dreamliner at Heathrow Airport in 2013.

New analysis examines the possibility of using in vitro gametogenesis (IVG) for human reproduction. IVG derives gametes from induced pluripotent stem cells (capable of giving rise to several different cell types) or human embryonic stem cells.

It's not ready for human procreation but it's a good idea to start discussing the implications in case it ever is, according to a study in the Journal of Law and the Biosciences.
