The blood may hold clues to some of COVID-19’s most mysterious symptoms
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...
Intriguing science discoveries of 2022
For the past three years, the COVID pandemic altered virtually every aspect of our lives. But we’ve been in a transitional phase in 2022, shifting towards the new normal. Science at Rockefeller has been in transition, too. Deeper insights into the nuances of COVID infection emerged,...
Rogue enzymes cause numerous diseases. A new method could help design drugs to treat them.
...The paper, published in the Journal of the American Chemical Society, describes how researchers used this innovative new platform to design molecules that take aim at helicases involved in COVID and certain cancers. "High-resolution structural and biochemical data alone are not sufficie...
Waddling water bears, grandmother neurons, and other memorable science stories of 2021
...Basic biomedical research went on, unabated, through the second year of New York City's touch-and-go battle with COVID. Investigations into the nature of the novel coronavirus and its intractable variants intensified, demanding the attention of more than 25 Rockefeller laboratories, all...
A third vaccine dose may increase protection from Omicron
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...
Llama antibodies could help fight SARS-CoV-2 variants
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...
Lonely flies, like many humans, eat more and sleep less
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...
COVID-19 immunology study reveals universally effective antibodies
...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 ...
Natural infection versus vaccination: Differences in COVID antibody responses emerge
...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...
Rockefeller saliva test for COVID-19 outperforms commercial swab tests
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, ...
