NewsCan a compound produced by deep-sea bacteria treat cancer?
Investigators purified a long-chain sugar molecule, or exopolysaccharide, from deep-sea bacteria and demonstrated that it triggers pyroptosis—an inflammatory form of programmed cell death—to inhibit tumor growth.

NewsCertain fungi can boost the micronutrient content of bread wheat
New research indicates that bread wheat’s micronutrient content can be increased by cultivating it with a specific type of fungus. Crops grown with the arbuscular mycorrhizal fungus Rhizophagus irregularis developed larger grains with greater amounts of phosphorus and zinc.

NewsHow does infection with respiratory syncytial virus affect the health of older adults?
Adults aged 65 and older hospitalized for RSV in Ontario experienced significantly higher rates of adverse outcomes such as longer length of hospital stay, transfer to intensive care, and 30-day mortality, compared with patients hospitalized with influenza, urinary tract infection, or fracture.

NewsTiny soil microbes turn detective to uncover the timeline of oil spill contamination
Scientists in Belfast and Nigeria have developed a diagnostic tool that deploys microbes to uncover the timeline of crude oil contamination in soils.

NewsStudy discovers that soft drinks affect the communication of gut bacteria and the immune system
Gut bacteria can adapt to environmental changes through DNA inversions. Researchers investigating how these DNA inversions occur found that consuming soft drinks, which contain white sugar, can alter the DNA of gut bacteria and, in turn, impact the host’s immune system.

NewsProbiotics can help or hinder gut recovery after antibiotic treatment
All probiotics are not created equal, according to new research. In a mouse model, researchers found that different probiotic strains can either accelerate or delay the gut microbiome’s recovery after antibiotic treatment.

NewsVitamin D deficiency increases risk of COVID-19 hospitalization
Experts say it’s not just booster shots that could offer protection against Covid-19 – healthy levels of vitamin D may also play a role. Researchers found a clear link between low vitamin D levels and an increased risk of being hospitalised by the virus.

NewsCo-infections in young bats could underpin coronavirus emergence
A new study finds that young bats are infected more frequently by coronaviruses and could be a key source of viral spillover into other species. It also reveals the dynamics of coronaviruses circulating in Australian bats, which pose no known risk to humans.

NewsStudy identifies world-first treatments to prevent a life-threatening virus infection
A study found two HIV antivirals already on the market can suppress transmission of HTLV-1 in humanised mice and prevent disease. When used in combination with a compound that induces cell death, infected cells were killed – flagging a potential future curative strategy.

NewsInhaled agricultural dust disrupts gut health
Inhaling agricultural dust may pose significant risks to gut health for workers in animal agriculture, a new study has found. Inhaling hog farm dust alters the gut microbiome and impairs intestinal function, including increased “leaky gut” or intestinal permeability.

NewsFermented stevia leaf extract has potential as anticancer treatment, researchers find
Stevia may provide more benefits than as a zero-calorie sugar substitute. When fermented with bacteria isolated from banana leaves, stevia extract kills off pancreatic cancer cells but doesn’t harm healthy kidney cells, according to a research team.
