UCLA researchers recently developed a smartwatch prototype that can measure and interpret the amount of stress hormones in sweat.
The watch, as described in a Science Advances research article published in January, allows wearers to identify their stress levels.

Recent UCLA-led research found becoming infected with COVID-19 while pregnant could result in damage to the infant’s immune system.
The study, published on Nov. 16, examined the consequences of mother-to-child transmission of COVID-19 when the infants tested negative for the virus itself.
