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.

How heatwaves are affecting Arctic phytoplankton      (via sciencedaily.com)     Original source 

The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling phases after or between heatwaves.

Magnetic imprint on deconfined nuclear matter      (via sciencedaily.com)     Original source 

Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
