Decades-Past Logging Still Threatens Spotted Owls in National Forests

Logging of the largest trees in the Sierra Nevada’s national forests ended in the early 1990s after agreements were struck to protect species’ habitat.

ShakeAlert System Continues Progress toward Public Use

A decade after beginning work on an earthquake early warning system, scientists and engineers are fine-tuning a U.S. West Coast prototype that could be in limited public use in 2018.

Stress Test: New Study Finds Seals are Stressed-Out by Sharks

Researchers test the effects predators have on their prey’s cortisol levels in the wild

NASA Gets a Final Look at Tropical Cyclone Ockhi's Rainfall

Tropical Cyclone Ockhi is quickly weakening in the Arabian Sea and is expected to dissipate on Dec. 6 when it makes landfall in northwestern India. The Global Precipitation Measurement mission or GPM core satellite passed over Ockhi and looked at its rainfall as wind shear was affecting the storm.  

Seaweed Could Hold Key to Environmentally Friendly Sunscreen

A compound found in seaweed could protect human skin from the damaging impact of the sun without causing harm to marine ecosystems. 

Working in the Cold

When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now, Chinese scientists have offered a strategy to avoid plunging battery kinetics. In a study published in the journal Angewandte Chemie, they designed a battery system with a cold-enduring hard-carbon anode and a powerful lithium-rich cathode, with the important initial lithiation step integrated.

WASP-18b Has Smothering Stratosphere Without Water

A NASA-led team has found evidence that the oversized planet WASP-18b is wrapped in a smothering stratosphere loaded with carbon monoxide and devoid of water. The findings come from a new analysis of observations made by the Hubble and Spitzer space telescopes.

Beyond Wind Speed: A New Measure for Predicting Hurricane Impacts

Six major hurricanes that engulfed the Atlantic Basin in 2017 were a devastating reminder of the vulnerability of coastal communities, where more than half the U.S. population resides.

Obesity Prevented in Mice Fed High-Fat Diet

Researchers at Washington University School of Medicine in St. Louis have identified a way to prevent fat cells from growing larger, a process that leads to weight gain and obesity. By activating a pathway in fat cells in mice, the researchers found they could feed the animals a high-fat diet without making them obese.

Augmented-Reality Technology Could Help Treat 'Lazy Eye'

When signals between the brain and one eye go awry, input from the other eye can become predominant, a condition called amblyopia or “lazy eye.” Amblyopia is common and it is typically treated by forcing the less dominant eye to adapt, either through lab-based training or wearing an eyepatch. But new research suggests that people may be able to use wearable augmented-reality technology to reduce this visual discrepancy as they go about everyday activities.
