Clean Energy: Experts Outline How Governments Can Successfully Invest Before It's Too Late

Governments need to give technical experts more autonomy and hold their nerve to provide more long-term stability when investing in clean energy, argue researchers in climate change and innovation policy in a new paper published today.

Researchers Model Optimal Amount of Rainfall for Plants

Researchers have determined what could be considered a “Goldilocks” climate for rainfall use by plants: not too wet and not too dry. 

Satellite Tracking Provides Clues About South Atlantic Sea Turtles' 'Lost Years'

A University of Central Florida biologist whose groundbreaking work tracking the movements of sea turtle yearlings in the North Atlantic Ocean attracted international attention has completed a similar study in the South Atlantic with surprising results.

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.
