Invasive Cuban Treefrogs Leap Out of Florida, Establish First Known Population in Louisiana

A population of exotic invasive Cuban treefrogs has been discovered in New Orleans, more than 430 miles (700 kilometers) from the nearest known population in Florida, making this the first known breeding population in the mainland United States outside that state, reports a new study by the U.S. Geological Survey.

Many Low-Lying Atoll Islands Will Be Uninhabitable by Mid-21st Century

Sea-level rise and wave-driven flooding will negatively impact freshwater resources on many low-lying atoll islands in such a way that many could be uninhabitable in just a few decades.

Early Treatment for Leg Ulcers Gets Patients Back on Their Feet

Treating leg ulcers within two weeks by closing faulty veins improves healing by 12% compared to standard treatment, according to new findings.

Tiny microenvironments hold clues to ocean nitrogen cycle

Nitrogen is essential to marine life and cycles throughout the ocean in a delicately balanced system. Living organisms—especially marine plants called phytoplankton—require nitrogen in processes such as photosynthesis. In turn, phytoplankton growth takes up carbon dioxide from the atmosphere and helps regulate global climate.

Soccer Heading—Not Collisions—Cognitively Impairs Players

Worse cognitive function in soccer players stems mainly from frequent ball heading rather than unintentional head impacts due to collisions, researchers at Albert Einstein College of Medicine have found. The findings suggest that efforts to reduce long-term brain injuries may be focusing too narrowly on preventing accidental head collisions. The study published online today in the Frontiers in Neurology.
