Researchers have evaluated the possibility of alerting drones equipped with automated external defibrillators (AED) to patients with suspected cardiac arrest. In more than half of the cases, the drones were ahead of the ambulance by an average of three minutes. In cases where the patient was in cardiac arrest, the drone-delivered defibrillator was used in …
Drones enabled the use of defibrillators before ambulance arrival Read More »
Researchers have devised a way to produce chemicals used in medicine and agriculture for a fraction of the usual cost. Using oxygen as a reagent and copper as a catalyst to break organic molecules’ carbon-carbon bonds and convert them into amines, which are widely used in pharmaceuticals. Traditional metal catalysis uses expensive metals such as …

Identifying how and why Antarctica’s major ice sheets behaved the way they did in the early Miocene could help inform understanding of the sheets’ behavior under a warming climate. Together, the ice sheets lock a volume of water equivalent to more than 50 meters of sea level rise and influence ocean currents that affect marine …

Consumer skepticism about the taste of vertically farmed greens is widespread. But a scientific taste test shows that respondents rate greens grown vertically and without soil as just as good as organic ones.
