Night-time heat significantly increases the risk of stroke      (via sciencedaily.com)     Original source 

Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care.

Warming climate intensifies flash droughts worldwide      (via sciencedaily.com)     Original source 

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.

New research reveals that prehistoric seafloor pockmarks off the California coast are maintained by powerful sediment flows      (via sciencedaily.com)     Original source 

New research on a field of pockmarks -- large, circular depressions on the seafloor -- offshore of Central California has revealed that powerful sediment flows, not methane gas eruptions, maintain these prehistoric formations.

Can coal mines be tapped for rare earth elements?      (via sciencedaily.com)     Original source 

A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.

Electric school buses may yield significant health and climate benefits, cost savings      (via sciencedaily.com)     Original source 

Replacing diesel school buses with electric school buses may yield up to $247,600 in climate and health benefits per individual bus, according to a new study. The researchers found that these benefits -- including fewer greenhouse gas emissions and reduced rates of adult mortality and childhood asthma -- and their associated savings are strongest in large cities and among fleets of old (2005 and before) buses.

U.S. drought-monitoring system outpaced by climate changes      (via sciencedaily.com)     Original source 

A new study reports that the U.S. Drought Monitor's weekly maps of nationwide drought conditions -- which help direct emergency federal aid -- have captured the steady march of climate change, but the Drought Monitor has itself failed to adapt to that reality. Areas of the country are spending more and more time in severe drought conditions the Drought Monitor still considers to be rare occurrences. The consequences could be that swaths of the country -- particularly in the West -- may not receive aid in keeping with the enhanced risk of drought as periodic emergencies become persistent new realities.

Expanding on the fundamental principles of liquid movement      (via sciencedaily.com)     Original source 

We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile liquids move across surfaces -- to cover a wider range of volatile liquids. These findings have the potential to play a role in various liquid-based industries such as electronics cooling.
