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 platinum, silver, gold and palladium, but the researchers used oxygen and copper -- an abundant base metal.

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 a majority of cases.

Hikikomori is a pathology characterized by social withdrawal for a period exceeding six months. While first defined in Japan, the pathology is growing globally. To help better assess individuals for Hikikomori, researchers developed the the Hikikomori Diagnostic Evaluation, or HiDE, a diagnostic tool to be a guide on collecting information on the growing pathology.
