Like many people who got wind of this new research, I wondered: were those simple little supplements really a safety net between me and the pandemic?

A few weeks later, another study out of the Tehran University of Medical Sciences was bold enough to claim sufficient vitamin D levels were associated with less…

Users may welcome the update to personalize automated insulin dosing, but they still await a cure.

Sprawling effluent is already unsettling, but scientists now know this gushing goop also carries traces of our pharmaceuticals and personal care products. Extreme weather events remind us how fragile our nation’s wastewater management systems are in the face of climate change, but few of them even remove medical contaminants to begin with.

Despite a lack…
