Rising sea levels destroyed evidence of shell middens at many prehistoric coastal sites

In a new study, researchers confirm a theory from the 1970s that coastal hunter-gatherers processed much of their shellfish at the beach before returning with their meat to camps on higher ground, leaving the heavy shells by the water. This finding has dramatic implications for past analyses of hunter-gatherer diets -- because many beachside shell middens would now be destroyed or underwater due to past sea level rises since the last Ice Age.

Sustainable method to produce lifesaving opiate antidotes at reduced cost

Overdose from opiates has skyrocketed. According to the National Center for Health Statistics, on average, 130 Americans die every day from an opioid overdose. The high cost of antidotes such as NARCAN® prevents many first responders from having access to lifesaving antidotes when they need it most. Researchers have identified a new method of producing these compounds using a microorganism discovered in a waste stream associated with processing of opium poppy.
