NewsLake Tahoe algae experiment suggests seasonal shifts ahead
As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakeswill likely experience seasonal changes, according to a new study. The effects of climate warming were especially pronounced in the colder months.

NewsScientists unbolt gateway to sharper CRISPR gene editing
Identifying the passwords for a certain CRISPR tool is a major stumbling block in discovering and characterising the CRISPR tool - but a team of scientists has cracked the code.

NewsValorization of soybean-processing wastewater sludge via black soldier fly larvae: performance and bacterial community dynamics
A new study indicates that the valorization of soybean-processing-sourced sludge via black soldier fly larvae was achieved via functionally important BSFL intestinal microbiota, providing an efficient recycling approach for similar waste streams.

NewsComparison of E. coli inactivation by UV222-ADPs and UV254-ADPs in water
A new study investigates advanced disinfection processes (ADPs) that use 222 and 254 nm far-ultraviolet radiation in conjunction with hydrogen peroxide (H2O2), sodium percarbonate (SPC), and persulfate (PDS) to inactivate E. coli in water.

NewsScientists research potential anti-ulcer vaccine targeting Helicobacter pylori
Scientists are on the way to finding a vaccine to fight off the Helicobacter pylori bacterium, possibly preventing stomach ulcers and lowering the risk for stomach cancer. They used immunoinformatics to scan its genetic makeup and predict which parts can trigger a strong immune response.

NewsRoot chemistry determines how antibiotic resistance spreads from manure to crops
Researchers found that the rhizosphere, the narrow soil zone surrounding plant roots, is a major hotspot for the accumulation of manure-derived ARGs. Across eight common crops, ARG abundance in rhizosphere soil was on average 1.24 times higher than in bulk soil.

NewsResearchers developing new easy-to-use viral biosensor test, giving patients more accurate and immediate results
An interdisciplinary team of researchers is creating a single low-cost test to detect HIV & Hepatitis B and C simultaneously, that may be used in resource-limited settings. With quicker and more accessible results, the test has potential to save lives.

NewsScientists reveal role of paeoniflorin in mediating microbiota-gut-brain axis
Paeoniflorin treatment significantly reduced depression-like behaviours in stressed rats, while gut microbiota analysis revealed that the treatment corrected imbalances in key metabolites associated with brain function, a study shows.

NewsFreshwater snails are an overlooked reservoir of AMR, study reveals
Freshwater snails across Africa and the UK carry bacteria containing a wide range of antimicrobial resistance (AMR) genes, including those predicted to confer resistance against last-resort antibiotics, according to a new study led by AMI members.

NewsTracking infectious disease spread via commuting pattern data
Researchers have introduced a Commuter Metapopulation Model (CMPM) to simulate the spread of COVID-19 with actual commuting data provided by the country’s second-largest telecommunication network, revealing it could better capture spatial variety in outbreak patterns.

NewsYeast survives Martian conditions, study shows
Life on Mars would have to contend with challenging conditions including shock waves from meteorite impacts and soil perchlorates. Scientists subjected Saccharomyces cerevisiae to these conditions, finding those that survived had assembled RNP condensates.

NewsWhen faucets rest: hidden microbial risks emerge in hours
Stagnant water in building plumbing systems is a well-known driver of microbial growth and contamination, including L. pneumophila. A new study highlights a short “microbial safety window” of 2–4 hours, after which risks increase significantly.

NewsData-guided bioelectrodes pave way for greener remediation
There is an urgent need to develop data-driven strategies that can accelerate and scale up microbial dechlorination for contaminated environments. Researchers report a new machine learning framework that integrates experimental features with microbial biofilm data to optimize bioelectrodechlorination.

NewsMaldives is first country to achieve ‘triple elimination’ of mother-to-child transmission of HIV, syphilis and hepatitis B
The World Health Organization has validated the Maldives for eliminating mother-to-child transmission of hepatitis B, while maintaining its earlier validation for EMTCT of HIV and syphilis. This makes the Maldives the first country in the world to achieve ‘triple elimination’.

NewsWHO warns of widespread resistance to common antibiotics worldwide
One in six laboratory-confirmed bacterial infections causing common infections in people worldwide in 2023 were resistant to antibiotic treatments, according to a new World Health Organization (WHO) report.

NewsTwo-dose recombinant shingles vaccine is effective even accounting for prior receipt of live shingles vaccine
A target trial emulation was conducted to assess the effectiveness of recombinant zoster vaccine (RZV) accounting for prior receipt of live zoster vaccine (ZVL) and immunocompetence. The results suggest individuals vaccinated with ZVL should be revaccinated with two doses of RZV.
