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.
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.
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.
El carbono que permaneció en los suelos de permafrost congelado para decenas de miles de años, está siendo liberado conforme las regiones árticas de la Tierra se calientan y está alimentando aún más el cambio climático global, según un investigador de la Universidad Estatal de Florida.
Robert Spencer, profesor adjunto de oceanografía, escribe en la revista Geophysical Research Letters que los organismos unicelulares llamados microbios, están devorando rápidamente el antiguo carbono que se libera de la descongelación del permafrost del suelo para finalmente liberarlo a la atmósfera en forma de dióxido de carbono. El aumento en los niveles de dióxido de carbono, por supuesto, hace que la Tierra se caliente y acelera la descongelación.
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.
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.
