NewsResearchers on the cusp of a vaccine for a global health threat
Researchers are on the cusp of a new vaccine to prevent chikungunya, a global health threat which attacks human joint tissue. The team tested whether they could engineer E. coli to assemble biopolymer particles which displayed chikungunya antigens and performed as a vaccine.

NewsResearchers probe how natto produces supersulfide molecules in fermentation
Natto, a Japanese food made from soybeans fermented with the Bacillus subtilis var. natto microorganism, is rich in supersulfide molecules, which are attracting attention in the medical and nutritional fields. Researchers extensively analyzed supersulfide content in natto fermentation using various methods.

NewsTesting menstrual blood for HPV could be “robust alternative” to cervical screening
Testing menstrual blood for human papillomavirus (HPV) could be a “robust alternative or replacement” for current cervical cancer screening by a clinician, finds a study. The researchers say using menstrual blood for HPV testing is convenient and non-invasive.

NewsGreen chemistry: Friendly bacteria can unlock hidden metabolic pathways in plant cell cultures
Co-culturing plant cells with harmless bacteria can expand the diversity of obtainable plant-derived compounds for pharmaceuticals, cosmetics, and agrochemicals, a new study shows.
-
NewsSugar molecules point to a new weapon against drug-resistant bacteria
Researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognise a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections.

NewsGut microbe–derived butyrate activates immune cells to enhance vaccine efficacy
Researchers have uncovered a new mechanism showing how butyrate—a short-chain fatty acid produced by gut commensal bacteria—enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.

NewsSoil pH shapes nitrogen competition between wheat and microbes, new study finds
A new study reveals that soil acidity plays a critical role in determining how wheat competes with soil microorganisms for nitrogen, a nutrient essential for plant growth and global food production.

NewsHow a single protein helps a fungal pathogen invade tea oil trees
Scientists report the discovery of a key mitophagy regulator in Colletotrichum camelliae, the fungus responsible for anthracnose in tea oil trees. A SUN family protein, CaSun1, directly recruits the autophagy protein CaAtg8 to mitochondria, enabling mitophagy during infection.

NewsClinical data gaps keeping life-saving antibiotics from children
Antibiotics that could treat severe infections in babies and children aren’t accessible due to a lack of data around safety and dosage. Of 12 antibiotics recommended for serious bloodstream infections caused by a harmful, Gram-negative bacteria, only six were licensed in children aged under 12 and just three in babies.

NewsScientists fight superbugs with nets, light switches - and egg white
A new gel could combat resistant bacteria in wounds and around implant sites, while also supporting healing. The hydrogel, which is inspired by natural immune defences, has produced highly promising results in animal models.

NewsHow brick-building bacteria react to toxic chemical in Martian soil
Researchers investigated how bacteria that can mould Martian soil into brick-like structures fare in the presence of perchlorate, a toxic chlorine-containing chemical discovered in Martian soil. It slows down bacterial growth - but surprisingly leads to the formation of stronger bricks.

NewsVaping zebrafish suggest E-cigarette exposure disrupts gut microbial networks and neurobehavior
Researchers hope to spark broader public discussion on the health risks of e-cigarettes and provide scientific evidence to support a reassessment of existing regulations.

NewsFrom sea to soil: Molecular changes suggest how algae evolved into plants
A research team used cryo-electron microscopy to look at the three-dimensional structure and function of Lhcp, a unique prasinophyte LHC, from the microscopic alga Ostreococcus tauri. The team compared their results to LHCII, which is found in terrestrial plants.

NewsResearchers uncover hidden toxin risks during nutrient-starved algal blooms
Researchers have shown that extended nutrient deprivation can significantly increase toxin content per cell in the benthic dinoflagellate Prorocentrum lima, even when cell numbers remain relatively stable. Toxin risk may increase quietly under nutrient-poor conditions without obvious bloom expansion.
