Affordable and available technologies can curb rising nitrous oxide emissions

Researchers from IIASA and the University of Maryland have found that nitrous oxide, a potent greenhouse gas and stratospheric ozone-depleting substance, could be readily abated with existing technology applied to industrial sources.

Laughing gas relieves symptoms in people with treatment-resistant depression

Researchers at Washington University School of Medicine in St. Louis and the University of Chicago have found that a single, one-hour treatment that involves breathing in a mixture of oxygen and the anesthetic drug nitrous oxide — otherwise known as laughing gas — can significantly improve symptoms in people with treatment-resistant depression.

Low doses of “laughing gas” could be fast acting, highly effective treatment for severe depression

A new study at the University of Chicago Medicine and Washington University found that a single inhalation session with 25% nitrous oxide gas was nearly as effective as 50% nitrous oxide at rapidly relieving symptoms of treatment-resistant depression, with fewer adverse side effects.

More than medicine: pain-relief drug delivers choices for mothers in labour

Choice and control are important factors for ensuring a positive childbirth experience, yet until recently, little was known about the impact of alternative administrations of fentanyl – one of the pain relief drugs used during labour– on both mother and baby.

COVID lockdown, seasonal changes affect California’s emissions

California’s nitrous oxide (NO₂) air pollution has been reduced by a combination of the state’s COVID-19 lockdown and naturally occurring effects, according to an atmospheric scientist at The University of Alabama in Huntsville (UAH)
