NewsScientists map the microbes behind a climate-regulating gas in India’s busiest estuary — a first
When bacteria in the water and sediment break dimethylsulfoniopropionate down, they release dimethylsulfide (DMS), a gas that drifts into the atmosphere and helps form clouds by seeding cloud condensation nuclei. A new paper reports the first-ever study of DMSP concentrations and the bacteria that degrade it along the entire length of the Cochin Estuary.

NewsResearchers discover a new antibiotic — and a new way to kill drug-resistant bacteria
Researchers have discovered a new antibiotic that kills some of the world’s most dangerous and drug-resistant bacteria by targeting a previously unknown vulnerability. Manikomycin has shown early effectiveness against priority pathogens including Salmonella, E. coli, and Klebsiella.

NewsLong-term biochar use can help cropland soils store more microbial carbon, but depth matters
A 12-year field study shows that biochar boosts stable microbial carbon in topsoil while reducing it in deeper soil layers, highlighting the need for depth-specific carbon management.

NewsStudy reveals core values that drive Black and Hispanic parents’ decisions on vaccinating their kids against COVID-19
Persistently low rates of COVID-19 vaccination in Black and Hispanic children suggest that parents in these communities tend to be hesitant about the vaccine for their kids, even when they have received it themselves. A new study sheds light on the factors influencing decisions about vaccination.

NewsAntibiotics for common sore throats have very limited effect on Strep spread
Antibiotics for sore throats have hardly any preventive effect against serious streptococcal infections in the population, according to a study. Instead, healthcare needs to quickly recognize warning signs of a serious infection.

NewsDengue vaccine shows favorable safety profile in travellers from non-endemic regions
A prospective study of more than 1,000 people vaccinated with TAK-003 in Catalonia found no serious adverse events and provides new evidence on the vaccine’s short-term safety in travelers.

NewsÖtzi and his microbiome: a 5,300-year-old relationship
Researchers have obtained a detailed picture of the microbial community associated with the Iceman mummy Ötzi. The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted yeasts.

News‘Baked’, printed, ready – premiere of architecture made from yeast
Researchers have developed a new, entirely bio-based material from a somewhat unexpected ingredient: yeast. The material is 3D printed and customised for use in architectural and interior design elements that are currently made from non-renewable or fossil-based materials, such as plaster, plastic or synthetic textiles.

NewsExtreme adaptation helps Dead Sea single-celled organisms to swim
Researchers have described in detail a structural adaptation supporting one of the Dead Sea’s few hardy inhabitants — a single-celled archaea called Haloarcula marismortui (H. marismortui). They characterized the proteins that form the archaeal filament, a long tail-like structure essential for movement.

NewsResearchers discover how to turn one germ’s drug resistance into an Achilles’ heel
As Mycobacterium tuberculosis mutates to protect itself from rifampicin, it also creates new weak points that other therapies could exploit. A new study shows that the most common rifampicin-resistance mutation slows bacterial RNA polymerase, creating vulnerabilities that future combination therapies may be able to target.

NewsThe brain, emotions, and the gut: How culture, stress, and social life shape gut health
A new study indicates that gastrointestinal health is influenced not only by genes, diet, and gut bacteria, but also by culture, social relationships, economic status, and the way individuals function within society.

NewsThe right heat makes biochar a better helper for food waste composting
A new study finds that hardwood biochar made at 400 °C best protects nitrogen during food waste digestate composting, offering a practical route to cleaner and higher-quality compost.

NewsT cells may be key to stopping measles virus—and its deadly relatives
Scientists have discovered how T cells target paramyxoviruses, a viral family that includes measles virus and Nipah virus. Instead of vaccinating against one virus at a time, the researchers found that activating “cross-reactive” T cells may protect against the wider paramyxovirus family.

NewsScientists recreate enterovirus infection in a new model of the human intestine
A miniaturized, biomimetic model of the human intestine successfully reproduced long-term enterovirus A71 (EV-A71) infection, report researchers. Using this innovative platform, they shed light on how this virus grows in the intestine without triggering a strong immune response.

NewsPopular GLP-1 drug may slow down biological aging in people with HIV
A new study provides the first randomized, placebo-controlled clinical evidence that semaglutide, a widely used GLP-1 drug, slows down the accumulation of biological aging markers in the DNA of adults with HIV.

NewsStudy identifies serious infection risks linked to targeted cancer therapies
A major real-world study has found serious blood-related side effects associated with antibody-drug conjugates, an increasingly important class of targeted cancer therapies. Some ADCs were associated with substantial rates of severe neutropenia – dangerously low levels of infection-fighting white blood cells – and related complications.

NewsMagnetic biochar gel helps keep arsenic and antimony out of rice
A new study reports a promising strategy for mining-impacted regions: a magnetic silicon-enriched biochar gel that can immobilize both arsenic and antimony in contaminated paddy soil and reduce their accumulation in rice grains.

NewsPhase 1 clinical trial set to begin on first leishmaniasis vaccine
A phase 1 clinical trial testing the safety of a leishmaniasis vaccine is set to begin in the coming months. The live vaccine, found to be safe in animals, is expected to be tested in humans later this year.

NewsResearchers evaluate NASA medication storage protocols
Researchers evaluated NASA’s medication handling practices, which currently call for removing medications from their original packaging and storing them in resealable plastic bags. The investigation found that active pharmaceutical ingredients degrade at a higher rate when stored in bags.

NewsNew study identifies key warning signs for infection after ankle fracture surgery in older patients
A new study of which patients are most at risk of a fracture-related infection post ankle surgery finds that low protein levels in the blood is the single strongest patient-related risk factor, making infection nearly 18 times more likely. Chronic alcohol abuse and failure to follow post-operative instructions each raise the risk more than fivefold.
