Genetic behavior reveals cause of death in poplars essential to ecosystems, industry

Oak Ridge National Laboratory

Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species’ inability to resist a pervasive and deadly disease. Their finding could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.

Two Degrees Decimated Puerto Rico’s Insect Populations

Rensselaer Polytechnic Institute (RPI)

While temperatures in the tropical forests of northeastern Puerto Rico have climbed two degrees Celsius since the mid-1970s, the biomass of arthropods – invertebrate animals such as insects, millipedes, and sowbugs – has declined by as much as 60-fold, according to new findings published today in the Proceedings of the National Academy of Sciences.

UCI Study: Reduced Sierra Nevada Snowmelt Runoff to Threaten California Agriculture

University of California, Irvine

An estimated three-quarters of the water used by farms, ranches and dairies in California originates as snow in the Sierra Nevada mountain range, but the future viability of that resource is projected to be at heightened risk due to global climate change.

Set in Amber, Fossil Ants Help Reconstruct Evolution of Fungus Farming

University of Wisconsin-Madison

A new study makes it clear that the constant threat of crop parasites repeatedly pushed evolution in strikingly similar directions in ants, creating structures that helped the ants reinforce their partnership with bacteria.

Now You Just Need to Remember to Exercise!

University of California, Irvine

People who include a little yoga or tai chi in their day may be more likely to remember where they put their keys. Researchers at the University of California, Irvine and Japan’s University of Tsukuba found that even very light workouts can increase the connectivity between parts of the brain responsible for memory formation and storage.

Full, but Still Feasting: Mouse Study Reveals How the Urge to Eat Overpowers the Signal to Stop

Michigan Medicine - University of Michigan

A new study explores the mystery of what drives eating past the point of fullness, at the most basic level in the brain. It shows that two tiny clusters of cells battle for control of feeding behavior -- and the one that drives eating overpowers the one that says to stop. It also shows that the brain’s own natural opioid system gets involved – and that blocking it with the drug naloxone can stop over-eating.
