NewsWearing face masks did not reduce risk of COVID infection after first Omicron wave, research shows
A study has found that wearing face masks did not lower the risk of Covid infection following the initial surge of the Omicron variant. Overseas travel was not associated with increased risk prior to February 2022, but then became a significant risk.

NewsAvian flu detected in New York City wild birds
A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, suggesting the interface between animals and humans that may give rise to zoonotic infections is not limited to rural environments and commercial poultry operations, but extends into urban centers.

NewsVirus that causes COVID-19 can penetrate blood-retinal-barrier and could damage vision
Using a humanized mouse model, researchers have discovered the virus that causes COVID-19 can breach the protective blood-retinal barrier with potential long-term consequences in the eye.

NewsStudy reveals how dopamine inhibits the expression of hepatitis B virus surface and e antigens
A new study finds that dopamine inhibits the expression of hepatitis B virus surface and e antigens - HBsAg and HBeAg - by activating the JAK/STAT pathway and upregulating ISG15 expression.

NewsYour Pseudomonas aeruginosa biofilm may vary - depending on where it turns up
The bacterium Pseudomonas aeruginosa adapts its biofilm form depending on the infectious site where it is found, potentially affecting antibiotic sensitivity, according to new research being presented at the Letters in Applied Microbiology ECS Research Symposium today.

NewsAutism’s missing microbes may influence social behavior by protecting the gut
Scientists have added to mounting evidence showing that microbes that live in our guts influence behavior. Specifically, they found that in mice, frequent gastrointestinal distress can reduce social behaviors—an effect that persists even after GI symptoms have subsided.

NewsNew method can help scan for new viruses on the horizon
The exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics, new current genetic analyses suggests.

NewsScientists uncover mechanism that could weaken virulence of Pseudomonas aeruginosa
Researchers have found a mechanism that makes it possible to weaken the virulence of opportunistic bacterial pathogen Pseudomonas aeruginosa - based on this knowledge, a new approach for antibiotics can be developed.

NewsA new acquired defense strategy different from CRISPR activates anti-mycobacteriophage immunity
A new study suggests endogenous insertion sequences (ISs) in mycobacteria can activate the defensive gene islands, thereby helping bacteria quickly acquire a broad-spectrum anti-phage ability.

NewsCommonly used antibiotic brings more complications, death in the sickest patients
Treatment with the commonly used antibiotic piperacillin/tazobactam was associated with a 5 percent increase in 90-day mortality, more days on a ventilator, and more time with organ failure for patients with sepsis, a new study finds.
