...A new paper in PNAS suggests there may have been a mathematical method, of sorts, to the madness of those early COVID days. The study tests a model that closely matches the patterns of case counts and deaths reported, county by county, across the United States between April 2020 and Jun...

The most severe cases of COVID-19 begin with leaky blood vessels. Breaches in the vascular system cause inflammation and coagulation, as fluid floods the lungs. Meanwhile, a host of seemingly unrelated symptoms set in. Blood pressure drops, arrhythmias test the heart, and the central nervo...

The mRNA vaccines used against COVID were never designed to battle the Omicron variant, a now dominant strain of the coronavirus that recently claimed 18,000 lives in a single week. Yet individuals who receive their third dose appear to be protected from the worst of Omicron, and a new stu...

Amid the growing threat of a new and potentially more dangerous SARS-CoV-2 variant, scientists are ramping up the quest for COVID treatments. A recent study demonstrates the therapeutic potential of an unusual class of immune proteins: miniature antibodies called nanobodies, derived from l...

COVID-19 lockdowns scrambled sleep schedules and stretched waistlines. One culprit may be social isolation itself. Scientists have found that lone fruit flies quarantined in test tubes sleep too little and eat too much after only about one week of social isolation, according to a new study...

...Efforts to combat COVID, Hepatitis B, and other infections bore fruit, and countless papers shed light on basic research, answering questions that have long baffled biologists. Here are some of the intriguing discoveries that came out of Rockefeller in 2023. Old sperm, new mutations As ...

...A study of 149 people who have recovered from COVID-19 shows that although the amount of antibodies they generated varies widely, most individuals had generated at least some that were intrinsically capable of neutralizing the SARS-CoV-2 virus. The findings are published June 18 in the ...

...Hope for a future without fear of COVID-19 comes down to circulating antibodies and memory B cells. Unlike circulating antibodies, which peak soon after vaccination or infection only to fade a few months later, memory B cells can stick around to prevent severe disease for decades. And t...

In the early days of the pandemic, with commercial COVID tests in short supply, Rockefeller’s Robert B. Darnell developed an in-house assay to identify positive cases within the Rockefeller community. It turned out to be easier and safer to administer than the tests available at the time, ...

...Soon after the world’s first COVID-19 vaccination campaigns kicked off, news emerged about new, more contagious SARS-CoV-2 variants crisscrossing the planet. The discovery of such strains in Britain, Brazil, and South Africa has raised a pressing concern: Will current vaccines be effect...
