What we need to worry about with avian flu—and what we don’t 
...You’d hope after the COVID pandemic that there’d be much more surveillance and screening. Instead, we have significant gaps in information. However, scientists are doing whatever they can. They’ve analyzed the sequence of the virus and calculated when this flu jumped from birds into cow...
Common mutation linked to COVID mortality
It may be the most baffling quirk of COVID: What manifests as minor, flu-like symptoms in some individuals spirals into severe disease, disability, or even death in others. New research published in Nature may explain the genetic underpinnings of this dichotomy.  The researchers demonstrat...
How antibody therapy impacts COVID vaccines
...The findings suggest that feedback inhibition increases the coverage provided by COVID vaccines in people who previously received monoclonal antibodies. "Depending on the virus, feedback inhibition can either enhance immunity or inhibit it," says Michel C. Nussenzweig, who co-led the st...
This technique for studying cell receptors could have sweeping implications for drug development
...While this work is the culmination of a team effort over a long period of time, Kotliar made herculean efforts to drag it across the finish line—shuttling samples and scarce reagents back and forth from Sweden in rare travel windows during COVID. It paid off. The results provide a handf...
Amid the rush for COVID-19 drugs, a case for the helicase
...Around the world, researchers working on developing treatments for COVID-19 are intensively examining each step of this process. Among them is Rockefeller’s Pels Family Professor Tarun Kapoor, whose lab has turned its expertise on stopping propagation of cancer cells to the virus, focus...
The common thread in severe COVID-19 
Patients who suffer from severe COVID-19 tend to have one thing in common: insufficient or defective proteins that help regulate the immune system, known as type I interferons (IFNs).   Two papers from the laboratory of Jean-Laurent Casanova previously demonstrated that at least 10 percent...
New design may boost potency of monoclonal antibodies against COVID
Monoclonal antibody drugs are among the few treatments available for COVID, providing a lifeline for those at high risk of severe illness and hospitalization. However, the usefulness of these drugs is limited because they are effective only when they can be administered early in the diseas...
Mathematical modeling suggests counties are still unprepared for COVID spikes
...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 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...
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...
