NewsRevealed: new factor associated with the risk of severe COVID-19 in people with obesity
By analyzing samples from obese non-diabetics, researchers found that high blood levels of saturated fatty acids cause pre-activation of innate immune cells that, when infected with SARS-CoV-2, produce elevated levels of inflammatory molecules.

NewsTreatment with a mixture of antimicrobial peptides can impede antibiotic resistance
A common infection-causing bacteria was much less likely to evolve antibiotic resistance when treated with a mixture of antimicrobial peptides rather than a single peptide, making these mixtures a viable strategy for new antibiotic treatments.

News Bacteria detected in tattoo and permanent makeup inks
Researchers have detected anaerobic and aerobic bacteria in commercial tattoo and permanent makeup inks. The findings demonstrate that the inks could be a source of human infections.

NewsMicroscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers
Melting Arctic glaciers are in rapid recession, and microscopic organisms colonise the newly exposed landscapes. A new study reveals that yeasts play an important role in soil formation in the Arctic after glaciers have melted away.

NewsResearchers examine how fungal toxins impact hormones in pregnancy
A fungal toxin that hinders animal fertility and fetal development may also disrupt human sex hormones in pregnancy, according to a study.

NewsChanging the gut microbiome boosts health outcomes for people newly diagnosed with metastatic kidney cancer
Researchers have developed a novel use of biotherapeutic product CBM588 in the treatment of cancer; new research suggests the agent adjusts people’s microbiome, possibly leading to enhanced effectiveness of FDA-approved cancer immunotherapies.

NewsBreakthrough research makes cancer-fighting viral agent more effective
Researchers from Aarhus University have made a significant breakthrough by discovering that the drug 4-OI can enhance the effectiveness of a cancer-fighting viral agent. This may lead to treatment of cancers that are otherwise resistant to therapies.

NewsBird flu stays stable on milking equipment for at least one hour
Bird flu, or H5N1 virus, in unpasteurized milk is stable on metal and rubber components of commercial milking equipment for at least one hour, increasing its potential to infect people and other animals, report researchers.

NewsCoumarin glycosides reverse enterococci-facilitated enteric infections
Researchers have developed a dietary therapeutic for enterococci-mediated infections.

NewsCommon respiratory infections may have protected children from COVID-19, study suggests
Analyzing nasal swabs taken during the pandemic, researchers suggest that the frequent presence of other viruses and bacteria may have helped to protect children from the worst effects of COVID-19 by boosting their immune systems.

NewsResearchers thwart resistant bacteria’s strategy
Researchers have discovered a weakness in Pseudomonas aeruginosa with the potential to become the target for a new way to attack it.
-
NewsDegradation of cell wall key in the spread of resistance
A new study shows how an enzyme breaks down the bacteria’s protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

NewsResearchers harness intratumoral microbiome against colorectal cancer
Scientists have established a microbiota-targeted drug delivery system that exhibits high efficiency in colorectal cancer targeting and colon retention.

NewsAI helps mine genetic elements from ancient genomes to tackle antibiotic resistance
Scientists have developed an artificial intelligence tool to mine the vast and largely unexplored biological data—more than 10 million molecules of both modern and extinct organisms— to discover new candidates for antibiotics.

NewsPotato blight pathogen probably originated in the Andes before spreading worldwide
A new study challenges the common theory that the devastating potato blight pathogen Phytophthora infestans originated in Mexico. Researchers meticulously reconstructed its global migration history and found it likely originated in the South American Andes before spreading globally. Source: Gareth James Famine memorial, Dublin. The potato blight pathogen ...

NewsFertilizer strategies can shape microbial communities in the rhizosphere
Fertilizer strategies can play a key role in the diversity of microbial communities in the crop rhizosphere, according to a new study.
-
NewsNew findings may fix the replicability crisis in microbiome research
Scientists report that daily fluctuations in the gut alter the microbiome so significantly that different bugs populate it in the morning and in the evening.

NewsImaging measles fusion process reveals pathway to powerful weapon
Scientists have harnessed an imaging technique called cryo-electron microscopy to show—in unprecedented detail—how a powerful antibody can neutralize the measles virus before it completes the process of fusing into the host cell membrane.

NewsWe should help coral microbial symbionts evolve heat tolerance in the lab, researchers say
Researchers discuss the potential of improving corals’ chances by inducing the evolution of heat tolerance in their symbionts—the mutualistic microbes that provide corals with nutrients in exchange for shelter and that are expelled during coral bleaching.

NewsMycena mushrooms have ’massively expanded’ genomes to make them more adaptable
A study of multiple Mycena mushroom species, also known as ‘bonnets’, reported in the journal Cell Genomics on June 27 has found that they have unexpectedly large genomes. Source: Arne Aronsen Mycena epipterygia While the mushrooms had been thought to live by degrading dead organic material alone, ...
