Does Science Support Lifting School Mask Mandates?

The CDC has given the OK to lift indoor mask mandates in much of the US, and a growing number of states no longer require face coverings in schools. But most experts agree that masks slow school spread of SARS-CoV-2, and whether now is the right time to allow teachers and students to unmask is a matter of debate.

Retrotransposon RNA Triggers NLRC4 Inflammasome Formation: Study

The CDC now suggests that only children who were within 3 feet, not 6 feet, of an infected student should quarantine, provided they were masked in a classroom. Does the science support this change?

Ancient Human Footprints in New Mexico Dated to Ice Age

Men given high doses of two antihistamine drugs did not experience the same benefits of high intensity interval training that men on a placebo enjoyed, revealing some of the molecular underpinnings of exercise’s effect.

Pharma Looks to Inflammasome Inhibitors as All-Around Therapies

Rachael Moeller Gorman | Apr 1, 2021 | 10+ min read

Many major biopharmaceutical companies are developing or acquiring drugs that target the NLRP3 inflammasome, a large intracellular complex that researchers say can spark inflammation and stoke diseases of lifestyle and aging.
