New research by the University at Buffalo Research Institute on Addictions has identified a key mechanism in how aerobic exercise can help impact the brain in ways that may support treatment — and even prevention strategies — for addiction.

The largest ice sheet on Earth was stable throughout the last warm period in geologic time, indicating it should hold up as temperatures continue to rise.

“STOP RIGHT THERE!” -  came the warning just as I was leaving the research building. Eric, peering out of an adjacent doorway whispered “He’s right around the corner next to you.”

Atmospheric scientists at the University of Alaska Fairbanks have launched an effort to better understand urban air quality problems in northern cities.

Human activity greatly impacts the natural chemistry of the largest river in North America — the Mississippi River. In a new, large-scale study, LSU geologists have identified a unique chemical signature in the river.

Threatened by the mosquito-borne Zika virus in 2016, Florida residents felt more susceptible than others in the United States to getting the virus, were more knowledgeable about it, and were more likely to support taking community action against it.

Surface air temperature (SAT) is a very important hydrological and climatic variable in western China. In contrast to the monsoon regions in eastern China, most regions in western China are arid, semi-arid or subject to snow cover. Thus, variations of SAT in summer in western China are key in connection with heat waves, the hydrological cycle, ecosystems and agriculture. The ability to predict SAT skillfully is an important target for science.

A Forest Service study of nearly 50,000 children in New Zealand has found that those who live in greener neighborhoods are less likely to develop asthma. However, not all greenness is a good thing—children living in areas with nonnative plant species or low plant diversity were actually at a greater risk of developing the chronic lung disease.

El Niño was long considered a reliable tool for predicting future precipitation in the southwestern United States, but its forecasting power has diminished in recent cycles, possibly due to global climate change. In a study published today in Nature Communications, scientists and engineers at the University of California, Irvine demonstrate a new method for projecting wet or dry weather in the winter ahead.

The world produces more corn by weight than any other cereal crop. Corn, also known as maize, is a staple food in many countries. But farmers growing corn face many challenges, such as drought, diseases, and pests.
