NewsHow an influx of salt may affect microbial ecosystems
Scientists find that as sea levels rise and saltwater seeps into freshwater, stressed aquatic populations may retain overall growth even as diversity declines.
-
NewsHow bacteria sacrifice themselves to render antibiotics ineffective
Bacteria can defend themselves against antibiotics with the help of an enzyme released by dying cells, reveals a study that helps scientists understand the survival mechanisms of bacteria and to improve the effectiveness of antibiotics.
-
NewsNew approaches against fungal infections discovered
Researchers have used state-of-the-art cryo-electron microscopy to decode the structure of a key fungal transporter - the UapA transporter of the model fungus Aspergillus nidulans.
-
NewsCyanobacterial toxins can be inhaled
Research on Southwest Florida cyanobacterial blooms shows that the toxins they produce are aerosolized, potentially being inhaled by people far from contaminated water bodies.
-
NewsHuman activities compromise coral health and resilience
Researchers discovered that 25 contaminants from agricultural, industrial, and pharmaceutical sources accumulated in the soft tissues of coral around Maui, Hawai‘i.
-
News COVID-19 booster strategies provide lasting immunity
Smaller doses of COVID-19 booster vaccines can provide long-lasting immunity, helping to reduce costs and improve access to vaccination, according to research. The findings could also inform vaccine dosing and options during future pandemics.
-
NewsDrug-resistant gonorrhea on the rise in Europe, ECDC warns
An increasing number of European countries have detected gonococcal strains resistant to the antibiotic ceftriaxone, the first-line drug to treat gonorrhea infection.
-
NewsROS–Jak2/Stat3 signaling drives HBV-induced liver inflammation
Scientists investigated the mechanisms underlying HBV-induced liver inflammation and identified a reactive oxygen species (ROS)-dependent signaling cascade that activates the Jak2/Stat3 pathway, thereby triggering hepatic inflammatory responses.
-
NewsNovel pathway suggests gut microbiome could be harnessed to lower blood pressure
The gut microbiome could potentially be harnessed to help lower blood pressure, according to a new study that identifies a previously unknown gut microbiota-bile acid signaling pathway targeting hypertension.
-
NewsSweeteners shown to slow growth of important gut bacteria in lab tests
Researchers have shown how commonly-used sweeteners slow the growth of certain gut bacteria. One sweetener in particular – combined with the anti-depressant duloxetine - significantly impaired two important gut bacteria linked to regulating blood sugar and gut health.
-
NewsNew class of fungi named after the King of Sweden
Researchers have discovered a completely new fungal species, which they chose to name after the King of Sweden. It is the first known representative of a new class of fungi that will be called Semicentenialomycetes.
-
NewsAntibiotic resistant gene found in Australian soil
A new study reveals a hidden source of antibiotic resistance. The novel gene found in contaminated freshwater NSW sediment provides bacteria with resistance to polymyxin - a critical last line antibiotic, used when others stop working.
-
NewsConnection between forests and rivers strengthens amphibians’ microbiome and protects them against a lethal fungus
A study indicates that a frog’s resistance to a fungus that has decimated hundreds of amphibian species worldwide is due not only to its genes, but also to the beneficial bacteria living on its skin and to the organization of its surrounding landscape.
-
NewsLow carbon dioxide levels improve microbial production of biodegradable plastic
In an innovative gas fermentation process, reducing concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic, poly[(R)-3-hydroxybutyrate]. The study provides a promising strategy for sustainable carbon recycling and efficient CO2 utilization.
-
NewsHow did the COVID-19 pandemic shift seasonal surges of other respiratory diseases?
A new analysis explores what underlies shifts in the timing of seasonal surges of respiratory diseases, as well as shifts in surges of heart-related deaths, that occurred after the COVID-19 pandemic began.
-
NewsScientists find hidden individuality in viral infections
An international team of researchers developed a new way to uncover hidden differences in how viruses infect and destroy individual microbial cells—solving a biological puzzle that has persisted for more than 80 years.
-
NewsBacteria form ‘herds’ to survive predators, offering fresh insight into Earth’s carbon cycle
Researchers have discovered that tiny photosynthetic bacteria band together into protective ‘herds’ when attacked by predators – a survival strategy that could also influence how carbon is stored in the world’s waters.
-
NewsMystery of why some toads survive deadly fungus revealed
The mystery of why some populations of amphibians recover following outbreaks of a deadly fungus has been solved in a new study. Researchers looked at peptides that the toads secreted from their skin – a key part of their immune defence.
-
NewsResearchers link gut microbe to cancer-fighting immune response
A new study is the first to show metabolites produced by certain bacteria in the gut can positively impact the body’s immune response to cancer.
-
NewsFirst-of-its-kind computer model of bacterial biofilms could support antibiotic resistance research
Faster and more effective ways to treat Pseudomonas aeruginosa could be on the cards thanks to a first-of-its-kind 3D computer model which shows how the bacterium grows and reshapes its protective layer and spreads to new surfaces.
