From building up defenses in the nose to slowing down a virus’s ability to make copies of itself, scientists are rolling out a raft of creative approaches to fighting infection
VIDEO: Some variants of SARS-CoV-2, such as Delta, will drive new waves of COVID-19 infections. What can previous studies of the flu, HIV and SARS tell us about the course that this pandemic may take?
VIDEO: New York Times science reporter Apoorva Mandavilli chronicles the rise of the delta variant, the latest of many twists in the pandemic that she’s covered since it began. Delta has left parents in an especially tough spot, with schools opening but young children still vulnerable.

OPINION: A massive bias in medical studies toward men of European origin means that genetic variants in understudied populations don’t get the focus they deserve
OPINION: Recent CDC guidelines for indoor air quality disregard the benefits of humidity. But research shows it can kill viruses and help thwart infections.
Of the millions of substances people encounter daily, health researchers have focused on only a few hundred. Those in the emerging field of exposomics want to change that.
New research, innovative programs and emboldened advocates are challenging decades-old conventions about how to respond to domestic abuse
