NewsStudy IDs secret of stealthy invader essential to ruinous rice disease
The virulence of a rice-wrecking fungus — and deployment of ninja-like proteins that help it escape detection by muffling an immune system’s alarm bells — relies on genetic decoding quirks that could prove central to stopping it.

NewsHistoric red tide event of 2020 fuelled by plankton super swimmers
The swimming ability of dinoflagellates lends them a competitive advantage over other plankton species, contributing to harmful algal blooms.

NewsDrinking water quality linked to lung infections in people with cystic fibrosis
High levels of some minerals and metals in environmental water supplies may increase the risk of nontuberculous mycobacteria (NTM) pulmonary infections in people with cystic fibrosis, according to a new study.
-
NewsTiny magnetic beads produce an optical signal that can detect pathogens
Engineers have identified a new optical signature in a widely used class of magnetic beads, which could be used to quickly detect contaminants in a variety of diagnostic tests.
-
NewsResistant E. coli rises despite drop in ciprofloxacin use
Community circulation of ciprofloxacin-resistant E. coli paradoxically increased after six-year reduction in antibiotic prescriptions.
-
NewsResearchers target lifecycle of parasite behind Chagas disease
Researchers are studying the signaling pathway that leads the parasite behind Chagas disease to transform and reproduce.
-
NewsSoil microplastics could usher superbugs into food supply
Micro- and nanoplastics in agricultural soil could contribute to antibiotic resistant bacteria with a ready route into our food supply, a new study warns.
-
NewsPocket-sized device for clinicians could spot infected wounds faster
An app-controlled device which uses heat signatures and bacterial fluorescence to identify infected wounds could help doctors and nurses catch and treat infections faster.
-
NewsResearchers decode new antibiotic clovibactin
Researchers have discovered and deciphered the mode of action of a new antibiotic, clovibactin, which is derived from a soil bacterium.
-
NewsNew insight into how bacteria surf cargo through the cell before division
Researchers have found some bacteria ship cellular cargo by ‘surfing’ along proteins called ParA/MinD ATPases.
-
NewsTick- and mosquito-borne diseases prevalent in shelter dogs
Ticks and mosquitoes are expanding their geographic range due to warming temperatures, frequently bringing disease, and a new study suggests shelter dogs in the eastern U.S. may be bearing the brunt of that burden.
-
News Mapping methane emissions from rivers around globe reveals surprising sources
Researchers have found that methane emissions in tropical aquatic habitats are comparable to those in the much colder streams and rivers of boreal forests and Arctic tundra habitats.
-
NewsTests of new antifungal therapy for fungal meningitis are successful
Researchers have successfully tested a new oral formulation of the antifungal medication amphotericin among people who had HIV and cryptococcal meningitis - a common fungal infection around the brain.
-
NewsHigh-fat diets alter gut bacteria, boosting colorectal cancer risk in mice
Scientists have pinpointed specific microbes and bile acids that become more prevalent in the guts of mice fed high-fat diets.
-
NewsEnergy depleting mechanism immunizes bacteria against phages
Researchers have described a new family of proteins that deplete cells of their energy, thereby protecting the cells from invaders. The previously unknown immune mechanism is used by many living creatures, from bacteria to bees.
-
NewsProtective particles allow engineered probiotics to report gut disease
Bioengineers have developed a platform that allows engineered biosensor bacteria safe passage through the gastrointestinal (GI) tract in an animal model.
-
NewsCommon wristbands are hotbed for harmful bacteria
A new study tested various textures of wristbands and their ability to harbour harmful pathogenic bacteria.
-
NewsRacial and ethnic differences in gut microbiome emerge at 3 months old
Gut microbiome variation associated with race and ethnicity arises after three months of age and persists through childhood, according to a new study.
-
NewsCommon cold virus exposure may help usher in immunity to Covid
Exposure to common cold-causing coronaviruses may contribute to pre-existing immunity to COVID-19, according to a new study.
