Retractions and controversies over coronavirus research show that the process of science is working as it should

Severe scrutiny of two major papers, including one about the effectiveness of hydroxychloroquine, is part of science's normal process of self-correction.

What makes a 'wave' of disease? An epidemiologist explains

There's no scientific definition for a wave of disease – and no evidence that the original onslaught of coronavirus in the US has receded much at all.

Group testing for coronavirus – called pooled testing – could be the fastest and cheapest way to increase screening nationwide

Screening multiple samples with a single test gets more people diagnosed using fewer supplies. Two health policy researchers explain how it works and how it could help the U.S.

Which drugs and therapies are proven to work, and which ones don't, for COVID-19?

During the last six months, news reports have mentioned dozens of drugs that may be effective against the new coronavirus. Here we lay out the evidence and reveal which ones are proven to work. Or not.

The US isn't in a second wave of coronavirus – the first wave never ended

The recent spike in new coronavirus cases in the US is not due to a second wave, but simply the virus moving into new populations or surging in places that opened up too soon.

Coronavirus and cancer hijack the same parts in human cells to spread – and our team identified existing cancer drugs that could fight COVID-19

Kinases are cellular control switches. When they malfunction, they can cause cancer. The coronavirus hijacks these kinases to replicate, and cancer drugs that target them could fight COVID-19.

A massive public health effort eradicated smallpox but scientists are still studying the deadly virus

The smallpox virus appears to have been with humanity for millennia before a global vaccination drive wiped it out. Current genome research suggests how smallpox spread and where it came from.
