NewsAntibiotics combat the gut bacteria that contribute to the pathogenesis of COVID-19
New research indicates that antibiotics can effectively target bacteria in the gut that harbor the virus that causes COVID-19 and produce toxin-like peptides that contribute to COVID-19-related symptoms. In the study, which involved 211 participants and was published in the Journal of Medical Virology, individuals who received ...

NewsDrug candidate may ‘unmask’ latent HIV-infected cells, mark them for destruction
Scientists have identified drug candidates that show promise to reverse the ability of HIV to escape detection by the immune system.

NewsClimate change alters the hidden microbial food web in peatlands
A study of protists shows that a neglected part of the peatlands’ microbial food web is sensitive to climate change, and in ways that are currently not accounted for in models that predict future warming.

NewsBacteria commonly found in the body contribute to stomach cancer, finds study
A new study has discovered that a type of bacteria commonly found in the body, which usually does not pose problems for healthy people, plays a significant role in causing stomach cancer, the fifth most common cancer in the world.

NewsProtein fragments ID two new “extremophile” microbes—and may help find alien life
Scientists used proteotyping to identify two potentially new types of extremophile bacteria. These results suggest proteotyping could be a more complete solution for identifying extremophile microorganisms from small biological samples.

NewsGut bacteria make neurotransmitters to shape the newborn immune system
Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.

NewsNewborn piglets serve as a model for studying influenza
A multidisciplinary team of researchers has studied newborn piglets to better understand the progression of influenza infections.

NewsWarning signs herald the development of antibiotic resistance
A new study shows how heteroresistance, a transient resistance common in many bacteria, can act as a precursor to the development of antibiotic resistance.

NewsStudy details how low humidity could be a boon for viruses
In reaction to the threat of COVID-19 and other viral, airborne respiratory infections, experts have recommended increased ventilation in hospitals, nursing homes, schools, and other public buildings. However, new research from Stanford University suggests that excess ventilation can reduce relative humidity in a way that could counteract ...

NewsGut bacteria important for overcoming milk allergy
Researchers led by Hiroshi Ohno at the RIKEN Center for Integrative Medical Sciences in Japan have discovered a link between gut bacteria and the success of milk-allergy oral immunotherapy. Published in the scientific journal Allergology International, the study found that Bifidobacterium—a genus of beneficial bacteria in the ...

NewsLongitudinal gut fungal alterations and potential fungal biomarkers for the progression of primary liver disease
Scientists have found that during liver disease progression, the abundance of Chytridiomycota increased initially, but was later replaced by Ascomycota in HCC.

NewsEven inactive smokers are densely colonized by microbial communities
Even inactive smokers are important locations for microbial activity and the production of organic carbon on the sea floor, reveals a study investigating what happens to biotic communities at hydrothermal vents when the source of hot fluids is lost.

NewsMutation linked to neurological disorders delivers double-pronged attack at cellular level
A mutation linked to neurological disorders knocks out not just one protein involved in translating the genetic code, but the entire cellular translation machinery. That’s the discovery of a team from the University of Maryland who were investigating how editing defects in threonyl-tRNA synthetase (ThrRS) work at ...

NewsInsights into release of fungal toxin promise progress in treating infections
The toxin Candidalysin of the yeast Candida albicans is incorporated into an unusual protein structure during an infection, and researchers have now succeeded in deciphering the function of this unusual arrangement.

NewsGenes identified that allow bacteria to thrive despite toxic heavy metal in soil
Some soil bacteria can acquire sets of genes that enable them to pump the heavy metal nickel out of their systems, a study has found. This enables the bacteria to not only thrive in otherwise toxic soils but help plants grow there as well.

NewsNewly identified yeast could prevent fungal infections by outcompeting rivals, study suggests
Researchers have identified a yeast that could be used to prevent invasive candidiasis, a major cause of death in hospitalized and immunocompromised patients.

NewsLong COVID ‘indistinguishable’ from other post-viral syndromes a year after infection
A team of scientists, including Queensland’s Chief Health Officer, say it is time to stop using terms like ‘long COVID’ as they wrongly imply there is something unique and exceptional about longer term symptoms associated with the virus.

NewsAge and sex associated with patient’s likelihood of antimicrobial resistance
A person’s age, sex and location are correlated with the chance that they have a bloodstream infection that is resistant to antibiotics, according to a new study.

NewsCellulose-degrading gut bacteria found in the human gut, although at lower levels in industrialized countries
Previously undescribed human gut bacteria that aid in the digestion of plant cellulose are scarce in urban societies but abundant in ancient and hunter-gatherer microbiomes, according to a new study.
