NewsEffectiveness of updated COVID-19 vaccines wanes moderately over time, is lower against currently circulating variants
New research shows boosters targeting omicron subvariants of SARS-CoV-2 are still providing reasonably durable protection against infection, hospitalization and death from COVID-19, but are less protective against the JN.1 strain.

NewsResearchers take step toward development of universal COVID-19 antibodies
Scientists have developed a promising new human monoclonal antibody that appears a step closer to a universal antibody cocktail that works against all strains of SARS-CoV-2.

NewsRisk of death from COVID-19 lessens, but infection still can cause issues 3 years later
A new study also shows that patients hospitalized within 30 days after infection face a 29% higher death risk in the third year compared with those not infected.

NewsNew antibiotic kills pathogenic bacteria, but spares healthy gut microbes
Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis while sparing healthy microbes in the mouse gut.

NewsClimate change is moving tree populations away from the soil fungi that sustain them
In response to climate change, trees, especially those in the far north, may be relocating to soils that don’t have the fungal life to support them, a new study finds.

NewsBiotech companies leverage novel tools to develop drugs for RSV
Reporter structures that can be introduced into cells for use in drug screening assays emit fluorescent or bioluminescent light at different intensities when RSV genes are inhibited by the potential antiviral agents being tested.
