NewsTurning agricultural waste into soil-building substances: Manganese-modified biochar gives fungi a powerful boost
A new study reveals how manganese-modified biochar helps beneficial fungi break down agricultural residues and accelerate the formation of valuable humic substances, offering a promising approach to sustainable organic waste recycling and soil improvement.

NewsStudy finds Helicobacter pylori exposure may be associated with more than one in five colorectal cancer cases worldwide
An international collaborative research study has found that exposure to Helicobacter pylori, a bacterium known to cause stomach ulcers and gastric cancer, may be associated with approximately 22% of colorectal cancer cases globally.

NewsResearchers engineer more sensitive CRISPR tool for virus detection
Researchers have engineered a more sensitive version of the RNA-targeting CRISPR enzyme Cas13a, improving its detection performance by 100-fold without sacrificing stability. The tool could support faster and more adaptable tests for HIV and a wide range of other RNA viruses.

NewsBacteria bond grains of sand into architectural elements
Cement manufacturing is one of the largest sources of CO2 emissions in the construction industry. One scientist is researching an alternative that works in a totally different way: instead of firing rocks at over 1,000°C, she is getting bacteria to bond grains of sand together into solid architectural elements.

NewsAspens ‘remember’ past drought in their leaves
Drought may leave more than narrow rings inside a tree trunk. New research suggests quaking aspen can retain a chemical ‘memory’ of dry years, changing the defensive compounds in their leaves and reshaping the fungal communities that live on them long after soils have rewetted.

NewsAn unusual bacterial defence system hides a powerful molecular switch
Researchers have uncovered a bacterial immune system that appears to work backwards. Unlike known retrons, which keep a toxin suppressed until infection, type VI retrons use phage-triggered DNA production to switch toxin activity on, revealing an unusually complex defence strategy that could inspire new gene-editing tools and antimicrobials.

NewsCoral heat tolerance depends on species and location
Not all corals cope with rising ocean temperatures in the same way. New research shows that heat tolerance can vary sharply between species and even between nearby populations, with some corals from cooler, more exposed reefs proving unexpectedly resilient to thermal stress.

NewsMicroalgae show promise as sustainable fertiliser for malting barley
New research has demonstrated that microalgae could provide a sustainable alternative to conventional mineral fertilisers for malting barley production. The study explored whether microalgae could help reduce the agricultural sector’s reliance on synthetic mineral fertilisers while maintaining crop performance and grain quality.

NewsResearchers explore link between gut, brain health for people with HIV
Oregon Health & Science University researchers have secured a $5.8 million, five-year federal award to investigate whether damage to the gastrointestinal tract contributes to neuroinflammation in people living with HIV — raising the potential for new treatments to preserve brain function in people with HIV and older adults.

NewsPL-5 spray improves healing in infected burn wounds, phase IIIb trial finds
A late-stage clinical trial found that a topical spray called peceleganan (PL-5) helped adults with mild infected burn wounds heal better than placebo. It enrolled 348 adults and compared the spray with a placebo. The study tested once-daily treatment for 14 days and tracked wound closure, bacterial clearance, and safety.

NewsGlobal Virus Network adds six centers of excellence and new affiliate across four continents
The Global Virus Network (GVN), a coalition of leading medical virologists representing more than 100 Centers of Excellence and Affiliates in more than 40 countries, has announced six new Centers of Excellence and one Affiliate in Austria, Brazil, China, India, Panama, Switzerland and the United States.

NewsResearchers target Zika-related eye damage with new antiviral strategies
Zika virus can damage the developing retina and optic nerve, leaving babies with lifelong vision problems. Researchers have now received $2.7 million to uncover how the virus disrupts eye development and test drug candidates that could protect vision, with some compounds also showing activity against dengue and West Nile viruses.

NewsDeadly fungus Candida auris reveals a new trick for escaping treatment
An accidental laboratory observation has uncovered a new way that Candida auris can survive antifungal treatment. Researchers found that the deadly hospital fungus can duplicate its entire genome and generate different cell populations, giving it more opportunities to adapt, mutate and evade drugs.

NewsScientists discover ‘D-rex’, a giant fungus from Chinese forests whose unique lineage dates back 65 million years
Deep in the forests of Yunnan, China, scientists have discovered a ‘fungal giant’ that challenges our understanding of how large fungi can become. The newly described species, Dianjunus rex, produces vertical fruiting bodies up to 50 cm high and weighing up to 2.2 kg – the largest known within the phylum Ascomycota.

NewsAn approach for novel antiviral compound discovery
Researchers in India have used an AI-based molecule generation platform to design a novel compound that computationally blocks one of the most conserved and functionally essential enzymes of SARS-CoV-2 — the main protease — with drug-like properties, no predicted toxicity, and a binding profile that compares favourably with clinically studied inhibitors.

NewsMount Sinai awarded five-year, $20.7 million vaccine development agreement to advance next-generation technologies against respiratory threats
Researchers at the Icahn School of Medicine at Mount Sinai have been awarded a five-year project agreement to develop Vaccine Immunoengineering for Targeted Antigen Presentation and Layered Control (VITAL), a research program exploring an improved approach to vaccination against respiratory pathogens.

NewsLong-term viral hepatitis control and changing patterns of liver cancer mortality in Japan
A review paper investigated how coordinated policy frameworks and robust epidemiological infrastructure have been associated with reductions in viral hepatitis–related HCC in Japan, and what gaps remain toward achieving hepatitis elimination.

NewsCholera cases surge as conflict in Yemen displaces over 200 000 people
Escalating conflict and mass displacement in Yemen are increasing the risk of infectious disease outbreaks as overcrowding, inadequate access to safe water and disrupted health services expose growing numbers of people to cholera, measles and other preventable diseases.

NewsBacteria DNA has evolved to withstand copper
Marine bacteria have evolved to bypass the copper-based coatings placed under ships to stop the growth of barnacles, algae, and other marine life. This necessitates new methods for managing biofouling — the unwanted accumulation of marine organisms — on ship hulls.

NewsAI could transform how laboratories detect rabies
Researchers have developed a world-first AI system that can detect rabies virus infection in cell cultures and measure protective antibody levels with high accuracy. The approach could make laboratory testing faster, more consistent and more accessible in countries where rabies remains endemic.
