Satellite Tracking Provides Clues About South Atlantic Sea Turtles' 'Lost Years'
December 6, 2017 04:08 PM - University of Central Florida

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
December 6, 2017 04:05 PM - University of Wisconsin-Madison

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.

Go with the flow (or against it)
December 6, 2017 08:30 AM - Queens University

Queen’s University researchers are using magnetic fields to influence a specific type of bacteria to swim against strong currents, opening up the potential of using the microscopic organisms for drug delivery in environments with complex microflows – like the human bloodstream.

“MTB have tiny (nanoscopic) organelles called magnetosomes, which act like a compass needle that helps them navigate to nutrient-rich locations in aquatic environments – their natural habitats – by using the Earth’s magnetic field,” says Dr. Escobedo. “In nature, MTB play a key role in Earth’s cycles by influencing marine biogeochemistry via transporting minerals and organic matters as nutrients.”

Avian Flu From Abroad Can Spread in North American Poultry, Wild Birds

Some avian influenza, or bird flu, viruses that are able to enter North America from other continents through migrating birds can be deadly to poultry and can infect waterfowl populations, according to a recently published U.S. Geological Survey study.

NASA Gets a Final Look at Tropical Cyclone Ockhi's Rainfall
December 5, 2017 12:48 PM - NASA/Goddard Space Flight Center

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
December 5, 2017 12:40 PM - Wiley

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.
