Scientists have recently developed a zinc battery with environmentally safe electrolytes from seafood wastes like shrimp and crab exoskeletons. Containing a gel-like electrolyte called chitosan, this zinc battery could store generated power from solar and wind sources. Biodegradable electrolytes are expected to break down within five months—as opposed to the polycarbonate separators of lithium-ion batteries, which may take centuries to diminish. Scientists are continually exploring other ways to make batteries environmentally friendly, with a particular focus on the manufacturing process. Read full article here

To curb drug deaths, communities turn to Reddit, texts and wastewater
With drug overdose deaths on the rise, authorities are attempting to curb the epidemic by tracking and sharing information in real time. In one unique effort, a nonprofit in New York City is using drug-testing equipment and stamping or marking habits of dealers to identify drug batches that may endanger users. Other approaches are also being used, such as monitoring drug-related chatter on Reddit and analyzing local wastewater for opioid and other drug levels. With the combination of these efforts, researchers hope to put a dent in the opioid crisis and reduce overdose deaths. Read full article here
