How Desalination Technology Is Helping Solve California's Drought
April 27, 2015 08:40 AM - Betty Ilovici, NoCamels
Four years of devastating droughts in California have pushed cities and counties in the Golden State to seriously consider turning to the one drinking source that is not depleting anytime soon – seawater. With the Pacific Ocean abutting their shores, water desalination may be the much-needed solution for Californians. But desalination has its disadvantages, the chief ones being the high costs and the potential environmental damage.
Aluminum-ion battery technology advances
April 27, 2015 06:56 AM - Mark Shwartz, The Ecologist
A new high-performance 'aluminum-ion' battery could be the technical breakthrough needed to boost the renewable energy takeover. It's safe, uses abundant low-cost materials, recharges in one minute and withstands many thousands of recharge cycles.
If this new battery lives up to expectations, it could propel a whole new chapter in the renewable takeover of the world's energy supply.
Stanford University scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting, inexpensive - and safe.
Nepal earthquake causes extensive damage and kills thousands
April 26, 2015 08:21 AM - AFP via Discovery News.
Powerful aftershocks rocked Nepal on Sunday, panicking survivors of a quake that killed more than 2,300 and triggering fresh avalanches at Everest base camp, as rescuers dug through rubble in the devastated capital Kathmandu.
A string of earthquakes have been occurring in Chile and Southern California.
How to help your brain age more slowly
April 25, 2015 08:16 AM - Laura Kurtzman, University of California San Francisco
Brains age, just like the rest of the body, even for those don't get neurological disease, according to an Institute of Medicine.
"Some of the changes that one observes doesn't mean that it's all over, gloom and doom," the committee’s vice chair, Kristine Yaffe, MD, told the Washington Post.
”‹While aging does more damage to some than others, most people can take steps to improve their health, according to Yaffe, the Roy and Marie Scola Endowed Chair and professor of psychiatry, neurology, and epidemiology at UCSF and chief of geriatric psychiatry and director of the Memory Disorders Clinic at the San Francisco VA Medical Center.
Mountains warming faster than expected
April 24, 2015 03:28 PM - Janet Lathrop, UMassAmherst
High elevation environments around the world may be warming much faster than previously thought, according to members of an international research team including Raymond Bradley, director of the Climate System Research Center at the University of Massachusetts Amherst. They call for more aggressive monitoring of temperature changes in mountain regions and more attention to the potential consequences of warming.
What's worse for polar bears- Global Warming or Pollution?
April 24, 2015 02:44 PM - Tim Radford, The Ecologist
As if melting ice in Polar bears' Arctic habitat was not enough, Norwegian scientists have found that organic pollutants such as pesticide residues are disrupting their thyroid and endocrine systems, adding a further threat to the species' survival.
Cross-species animal fights explained by new research
April 24, 2015 07:54 AM - UNIVERSITY OF CALIFORNIA - LOS ANGELES via EurekAlert
Why do animals fight with members of other species? A nine-year study by UCLA biologists says the reason often has to do with "obtaining priority access to females" in the area.
The scientists observed and analyzed the behavior of several species of Hetaerina damselflies, also known as rubyspot damselflies. For the study, published this month in the print edition of the journal Proceedings of the Royal Society B, researchers observed more than 100 damselflies a day in their natural habitat along rivers and streams in Texas, Arizona and Mexico.
Microbes have major effect on climate change
April 24, 2015 07:21 AM - Kathleen Haughney, Florida State University
Carbon, held in frozen permafrost soils for tens of thousands of years, is being released as Arctic regions of the Earth warm and is further fueling global climate change, according to a Florida State University researcher.
Cleaner buses could result in fewer school absences
April 23, 2015 12:32 PM - ClickGreen Staff, ClickGreen
The use of clean fuels and updated pollution control measures in the school buses 25 million children ride every day in the United States could result in 14 million fewer absences from school a year, based on a study by the University of Michigan and the University of Washington. In research believed to be the first to measure the individual impact on children of the federal mandate to reduce diesel emissions, researchers found improved health and less absenteeism, especially among asthmatic children.
What countries have the most endangered animals?
April 23, 2015 10:55 AM - Susan Bird, Care2
If you had to guess which countries are losing the greatest number of endangered mammals to extinction, which would you pick? Actually, you don’t have to guess. There’s a new map that will show you, in no uncertain terms, where in the world we’re losing animals the fastest. The top three “winners” of this unfortunate contest are Indonesia (184), Madagascar (114), Mexico (101), with India following close behind at 94.
