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.

NewsPersistent strain of cholera defends itself against forces of change, scientists find
A deadly strain of cholera bacteria that emerged in Indonesia back in 1961 continues to spread widely to this day, claiming thousands of lives around the world every year, sickening millions — and, with its persistence, baffling scientists. Source: CDC/ Dr. William A. Clark Under a magnification of ...

NewsHow researchers confirmed first case of avian influenza transmitted from cow to human
A new paper outlines how scientists detected the first case of highly pathogenic avian influenza (HPAI) A (H5N1) transmitted from a mammal to a human.

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.

NewsBirth by C-section more than doubles odds of measles vaccine failure
Researchers say it is vital that children born by caesarean section receive two doses of the measles vaccine for robust protection against the disease.

NewsFirst detection of hepatitis E virus from urban Norway rats in the Republic of Korea
Researchers have identified hepatitis E virus (HEV) in urban Norway rats (Rattus norvegicus) in the Republic of Korea (ROK) for the first time.

NewsWeaker ocean currents lead to decline in nutrients for North Atlantic ocean life during prehistoric climate change
Researchers at Georgia Institute of Technology have finished investigating how the prehistoric weakening of a major ocean current led to a decline in ocean nutrients and negative impacts on North Atlantic ocean life. The results support predictions about how our oceans might react to a changing climate — and what ...
