News American microbiologist behind global water safety breakthrough wins 2026 Lee Kuan Yew Water Prize
Professor Joan Bray Rose has been recognised for pioneering Quantitative Microbial Risk Assessment (QMRA) as a global approach for assessing pathogen risks in water. QMRA has been adopted into global drinking water standards and enabled safe water reuse.

News‘Safe’ fertilizer linked to extreme water quality loss in Canadian Prairies
Research has found that widespread application of the common farm fertilizer, urea, severely degrades water quality in the Canadian Prairies. Urea added to farm ponds increased growth of algae to levels 10 times higher than seen in other damaged ecosystems, such as Lake Winnipeg in Manitoba.

NewsIn developing immunity to allergens, a little ‘dirty’ goes a long way
Exposure to diverse microbes and proteins early in life creates broad immune memory and a specific antibody that helps block allergic reactions later in life. Rather than overreacting to harmless allergens, an experienced immune system responds in a balanced way.

NewsA closer look at immune ‘memory’ - and how long it lasts
A new review shares recent advances from the field of immune memory and highlights key steps we might take to develop even more effective, longer-lasting immunity against deadly diseases.

NewsMolecular biologist Li-Jun Ma wins 2026 Mahoney Life Sciences Prize
Li-Jun Ma has been chosen as this year’s winner of the Mahoney Life Sciences Prize for her work toward mitigating the effects of a fungal pathogen that is causing the functional extinction of the bananas most commonly found in U.S. supermarkets.

NewsStudy reveals hidden damage in stony corals using 3D imaging and AI
Researchers investigating how disease affects coral structure turned to X-ray microcomputed tomography which generates detailed 3D reconstructions down to microscopic pores, which reveal internal skeletal features, including porosity, thickness and structural orientation, in a non-destructive way.

NewsAI spots hidden behavior patterns in self-organizing bacteria
A custom-built artificial intelligence system has helped to uncover how bacterial communities organize themselves, showing that the earliest moments of a biological transition carry far more information than previously considered.

NewsUltrasensitive test reveals evidence of previously undetected tuberculosis in Boston Hospital patients
Researchers have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may be significantly underdiagnosed in the United States.

NewsNew bite-sized CRISPR molecule may open doors for therapeutic genome editing
The safest, most accurate gene-editing tools don’t fit inside viral delivery mechanisms that could target them to specific cell types or tissues inside the human body. Researchers have developed a smaller pair of “molecular scissors” for gene editing that could make site-specific delivery within the body possible.

NewsResearchers uncover how obesity impairs vaccine response
New findings reveal that obesity significantly impaired the quality and longevity of antibody responses to a Pseudomonas aeruginosa vaccine in a mouse model. The impaired antibody production was due to defects in germinal centers.

NewsShorter antibiotic courses show similar outcomes to longer use for some pneumonia patients
A multicenter target trial emulation found that for eligible patients hospitalized with community-acquired pneumonia (CAP), health outcomes were similar whether they received a three- to four-day course of antibiotics or a course lasting five days or more.

NewsNew biodegradable wash removes pesticides and extends produce shelf life
Researchers have developed a natural, biodegradable wash that removed up to 96 per cent of pesticide residue from fruit and slowed browning and moisture loss.

NewsTwo research projects to study immune responses to dengue and Zika viruses
Dr. James Earnest, an assistant professor at the Burnett School of Biomedical Sciences, is leading two new research projects to examine how humans build an immune response to dengue and the Zika virus over time, in pursuit of creating better preventative measures.

NewsWildlife trade increases pathogen transmission
A study combining forty years of legal and illegal wildlife import-export data with compilations of host–pathogen relationships found that wild mammals that are traded are 1.5 times more likely to share infectious agents with humans than those that are not involved in trade.

NewsResearchers explore potential link between COVID-19 and lung cancer risk
New findings have identified a potential association between COVID-19 and increased lung cancer risk, driven by underlying biological mechanisms in the lung. The study integrates human clinical data with mechanistic research in animal and cellular models.

NewsNanodisc platform improves vaccine design for Ebola, HIV and more
Scientists have created a platform that allows viral surface proteins to be studied in a form that more closely resembles how they appear naturally, utilizing nanodisc technology where these proteins are embedded into particles made of lipid molecules, preserving them in a membrane-like structure.

NewsNon-producing oil and gas wells emit microbial methane at rates 1,000 times higher than previously estimated
Microbial methane leaking from non-producing oil and gas wells is being emitted at rates about 1,000 times higher than previously estimated, according to a new study.

NewsHidden ocean feedback loop could accelerate climate change
Scientists have uncovered a key mechanism behind methane production in the open ocean. Their research indicates that this mechanism could intensify as the planet warms, providing an alarming feedback loop for global warming.

NewsTropical trees are more neighborly, study suggests
Tropical trees are better neighbors than trees in temperate forests, according to a new study. Trees growing closer to the equator have more positive interactions with their neighbors, which may help explain why tropical forests are home to so many tree species.

NewsA smarter way to build vaccines: scientists harness AI to target emerging alphaviruses
Scientists have developed a new computational pipeline that could dramatically accelerate the development of vaccines against a group of mosquito-borne viruses known as alphavirus.
