Will metal supplies limit battery expansion?
October 11, 2017 05:27 PM - Massachusetts Institute of Technology

The dramatic rise in production of electric vehicles, coupled with expected growth in the use of grid-connected battery systems for storing electricity from renewable sources, raises a crucial question: Are there enough raw materials to enable significantly increased production of lithium-ion batteries, which are the dominant type of rechargeable batteries on the market?

Making renewable power more viable for the grid
October 11, 2017 05:25 PM - Massachusetts Institute of Technology

Wind and solar power are increasingly popular sources for renewable energy. But intermittency issues keep them from connecting widely to the U.S. grid: They require energy-storage systems that, at the cheapest, run about $100 per kilowatt hour and function only in certain locations.

Living in Watersheds with More Trees Reduces Disease Risk
October 11, 2017 04:04 PM - Yale Environment 360

Diarrheal disease from contaminated water is the second leading cause of death among children under the age of five, claiming more than 360,000 lives annually. Now, a new study of children in 35 countries finds that those living in a watershed with more trees had a lower risk of contracting the illness.

Bycatch Responsible for Decline of New Zealand Sea Lion

Getting caught in fishing nets is a major cause of death for the increasingly endangered New Zealand sea lion, according to new research from the University of Otago, Massey University and the University of Toronto.

Solar Flux; From Bug to Feature
October 11, 2017 09:49 AM - SolarPACES

Excess solar flux could be harnessed and used to generate additional electricity at a tower CSP plant, by cladding part of the tower containing the receiver with photovoltaic (PV) panels, according to Sandia scientist Cliff Ho. He found that adding PV on the tower could generate over 10 MW, or 10% of the total capacity of a 100 MW CSP plant, using the same reflected sunlight off heliostats used to focus “suns” up onto the tower receiver for thermal solar generation.

Grazing Horses on Better Pastures
October 11, 2017 09:30 AM - American Society of Agronomy

When you picture a horse, you may imagine it grazing contentedly in a grassy pasture. Grazing lets horses move around naturally outdoors and socialize with other horses. And grass is an easily available, nutritious feed that horses like eating. If you have the land, providing pasture for horses is less costly than buying hay.

Nature Communications: A Specific Protein Regulates the Burning of Body Fat to Generate Heat
October 11, 2017 09:09 AM - Centro Nacional de Investigaciones Cardiovasculares

Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have identified a protein that holds promise as a target for therapies to reduce obesity. Drs. Guadalupe Sabio and Nuria Matesanz have demonstrated that MKK6 controls the conversion of fat stores, known as white fat, into brown fat, in which lipids are burned to maintain body temperature and reduce obesity. The study is published today in  Nature Communications.

Live Phone Calls Better Than Text Messages and Letters to Remind People About Colon Cancer Screening
October 11, 2017 08:58 AM - Kaiser Permanente

Live phone calls significantly outperform text messages and letters as a way to remind patients to complete and return at-home screening tests for colon cancer, according to new research in the Journal of General Internal Medicine.

Dual Project Supports Understanding of Climate Change and Astronomy
October 11, 2017 08:52 AM - University of Oxford

A team of researchers from across the country will work together to design a satellite instrument, which will sit on board the International Space Station (ISS). The technology will monitor the complex interaction between the Earth’s upper atmosphere and the climate, and could advance our understanding of earth observations and aeronomy. 

Tai Chi Holds Promise as Cardiac Rehab Exercise
October 11, 2017 08:48 AM - American Heart Association

The slow and gentle movements of Tai Chi hold promise as an alternative exercise option for patients who decline traditional cardiac rehabilitation, according to preliminary research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
