Since its inception in 1909, University of Minnesota Extension has worked with farmers to find solutions to their biggest challenges. And, since we all eat—our biggest challenges. For the past 25 years, Extension has shared the U’s expertise by educating agriculture professionals, who in turn have the most influence on crop farmers today.
Keeping agriculture professionals on top of current research helps ensure economically and environmentally responsible cropping decisions are made throughout the state. (more…)
Oil and gas development continues to press into the most remote corners of the western Amazon, one of the most biologically and culturally diverse zones on Earth. Now a study proposes a new 10-point, best-practice framework that combines technical engineering criteria with consideration of ecological and social concerns to reduce the negative impacts of Amazonian hydrocarbon exploration and production.(more…)
Improvised explosive devices (IEDs) are becoming a global problem for the U.S. armed forces. To prevent injuries to soldiers and provide better care to those who are injured, the U.S. military is striving to better understand how blasts impact the human body.(more…)
Using a state-of-the-art DNA sequencing technique, UA researchers have discovered genetic mutations underlying seizure disorders in previously undiagnosed children
Researchers at the University of Arizona have successfully determined the genetic mutations causing severe epilepsies in seven out of 10 children for whom the cause of the disorder could not be determined clinically or by conventional genetic testing.(more…)
Scientists use satellites, underwater robot to study Atlantic sturgeon migrations
More than a century ago, an estimated 180,000 female Atlantic sturgeon arrived from the coast in the spring to spawn in the Delaware River and fishermen sought their caviar as a lucrative export to Europe. Overfishing contributed to steep population declines, however, and today numbers have dwindled to fewer than 300 adults.
Researchers at the University of Delaware and Delaware State University are using satellites, acoustic transmitters, an underwater robot and historical records to pinpoint the ocean conditions that the fish prefer during migrations — and potentially help fishermen avoid spots where they might unintentionally catch this endangered species.

Some plants, such as succulents, have managed to grow very plump leaves. For that to happen, according to a new study in Current Biology, plants had to evolve 3-D arrangements of their leaf veins in order to maintain adequately efficient hydraulics for photosynthesis.
PROVIDENCE, R.I. [Brown University] — A garden variety leaf is a broad, flat structure, but if the garden happens to be somewhere arid, it probably includes succulent plants with plump leaves full of precious water. Fat leaves did not emerge in the plant world easily. A new Brown University study published in Current Biology reports that to sustain efficient photosynthesis, they required a fundamental remodeling of leaf vein structure: the addition of a third dimension.
