Amounts of organic molecules in planetary systems differ from early on

A study of 50 protoplanetary-disk forming regions found differences in the abundance of complex organic molecules, with some regions having higher concentrations of methanol and acetonitrile. The findings suggest a possible common production mechanism for these molecules, shedding light on their formation in space.

Popeye with a whiff of rotten eggs

A study by researchers at the University of Konstanz and Vienna discovered that specialized gut bacteria cooperate to process sulfoquinovose, a sulfonic acid derivative found in green vegetables. The analysis revealed that this process produces hydrogen sulfide, which has disparate effects on human health.

Bird blood is a heating system in winter

Researchers discovered that bird blood functions as a central heating system when it is cold, thanks to the presence of mitochondria. The study found that birds produce more heat through their blood cells during winter, challenging the common assumption that shivering and fluffing feathers are the primary methods for thermoregulation.

Frontline health workers across US faced unique stressors during COVID

A recent study by the University of California - San Francisco found that nearly one-fifth of emergency department staff were at elevated risk for post-traumatic stress disorder (PTSD) due to COVID-19. Regular testing for COVID-19 helped reduce stress among emergency personnel, particularly those with previous positive antibody results.
