NewsBreakthrough study shows coral reefs will transform but can persist, if carbon is curbed
In a breakthrough study published this week in Proceedings of the National Academy of Sciences, researchers in the Hawaiʻi Institute of Marine Biology (HIMB) at the University of Hawai‘i (UH) at Mānoa have shown that, contrary to most projections, coral reefs are not inevitably doomed, but have the potential to ...

NewsNot the usual suspects: Novel genetic basis of pest resistance to biotech crops
A study reveals a novel genetic basis of resistance to transgenic crops in the corn earworm. To gain protection from this pest, crop plants had been genetically engineered to produce proteins from the common bacterium Bacillus thuringiensis, or Bt.

NewsStudy reveals stubborn mistrust in COVID-19 vaccine science
A new study sheds light on public trust in COVID-19 vaccine science and its impact on vaccine acceptance in the United States from 2021 to 2023, finding that around one-third of respondents expressed mistrust in the science behind COVID-19 vaccines.

NewsScientists examine how wastewater practices in Florida Keys impact water quality
A new study has tracked how wastewater nutrients migrate from disposal sites in the Florida Keys, and the results have already informed wastewater practices in the region.

NewsNew findings on animal viruses with potential to infect humans
Scientists investigating animal viruses with potential to infect humans have identified a critical protein that could enable spillover of a family of organisms called arteriviruses.

NewsEnhanced screening methods prevent spread of drug-resistant fungal infections in hospitals
Researchers have enhanced hospital screening protocols for Candida auris, an often drug-resistant fungal pathogen. These new guidelines could promote early detection of the harmful fungus in high-risk patients and prevent hospital outbreaks.

NewsWater fern offers safe potential global food insecurity solution - with no cyanotoxins
An international effort to test Azolla found that it does not contain cyanotoxins, potent toxins produced by a type of cyanobacteria, or blue-green algae, associated with the plant.

NewsStudy sheds light on increased rates of severe human infections caused by Streptococcus subspecies
An increase in rates of severe invasive infections becoming resistant to key antibiotics has a team of infectious disease researchers studying a recently emerged strain of bacteria called Streptococcus dysgalactiae subspecies equisimilis (SDSE).

NewsHistones show promise against bacterial infections
Scientists have outlined that human histones have antimicrobial activity against different bacteria, including biofilms of Pseudomonas aeruginosa, one of the six most resistant bacteria in the world.

NewsExperts recommend considering dietary factors in probiotics and prebiotics research
A new Perspective paper finds that, while diet is a major determinant of gut microbiome composition and function, it has rarely been incorporated as a variable in research on the efficacy of probiotics and prebiotics.

NewsAI tackles huge problem of antimicrobial resistance in intensive care
Artificial intelligence (AI) can provide same-day assessments of antimicrobial resistance for patients in intensive care – critical to preventing life-threatening sepsis.

NewsInfant gut microbiota development predicts future health
Infants’ gut microbiota development follows one of five predictable trajectories, significantly influenced by infant exposures, according to a new study. These are strong indicators of later health outcomes, including allergies, growth patterns, and infections.

NewsA lung pathogen’s dilemma: infect or resist antibiotics?
Research has uncovered how Pseudomonas aeruginosa manages the trade-off between colonizing and surviving during infection by switching between biofilm formation for antibiotic protection and a more mobile, “planktonic” state to spread and access nutrients.

NewsBeneficial gut microbe has surprising metabolic capabilities
To address childhood malnutrition — which affects 200 million children globally — researchers at Washington University School of Medicine in St. Louis developed a therapeutic food that nourishes the collections of beneficial microbes that reside in the gut, and improves children’s growth and other measures of their health. ...

NewsGut bacteria transfer genes to disable weapons of their competitors
New research shows how common gut bacteria tame their antagonistic neighbors by transferring genes that change their weapon systems.

NewsBacteria and fungi found on bat wings that could help fight deadly white-nose syndrome
Bacteria and fungi from the wings of bats could play a significant role in saving them from white-nose syndrome (WNS), a fungal disease affecting the skin of wings and muzzle, which has nearly wiped out vulnerable bat populations across North America.

NewsA metabolic secret of ethane-consuming archaea unraveled
Scientists have presented a study on the degradation of ethane, the second most abundant alkane in seeps on the deep seafloor. They characterized enzymes involved in the process and found that their reaction breaks an established dogma in the field of anaerobic biochemistry.
