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.

NewsResearcher studying probiotics to fight acid reflux and esophageal cancer
Patients with acid reflux, which occurs when stomach acid pushes up into the esophagus, know the symptoms all too well: heartburn, belching, chest pain and trouble swallowing. Acid reflux also increases the risk of esophageal cancer, but researchers are investigating how a simple probiotic could treat and prevent both conditions.

NewsNew climate-based tool predicts coral bleaching months in advance
Researchers found that coral bleaching on a Caribbean island occurs when three major climate patterns in the Pacific and Atlantic Oceans align in specific ways that intensify ocean warming. They created a new, early-warning tool called the Bleaching Event Early Predictor (BEEP).

NewsThe future of phage therapy will be decided by more than science alone
As antimicrobial resistance accelerates worldwide, leading experts gather in Valencia to address the scientific, regulatory, manufacturing and clinical challenges that will determine whether phage therapy becomes a routine healthcare solution.

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.

News CEPI fast-tracks three Bundibugyo ebolavirus vaccine candidates
The Coalition for Epidemic Preparedness Innovations (CEPI) will urgently accelerate development of three investigational vaccines targeting the Bundibugyo ebolavirus that has caused a rapidly spreading epidemic in the Democratic Republic of the Congo (DRC) and neighbouring Uganda.

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.

NewsGladstone launches Center for PhAIge Therapy to harness AI in the fight against drug-resistant infections
Gladstone Institutes has received funding to establish the Center for PhAIge Therapy, a research center that will develop new phage-based treatments for antibiotic-resistant bacterial infections. The five-year grant makes Gladstone one of three institutions across the country selected to lead this coordinated effort.

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.

NewsBiomaterial made from jackfruit latex is a promising treatment for periodontitis
Researchers have developed a biomaterial containing jackfruit latex, pomegranate peel extract, and simvastatin that shows promising efficacy in treating periodontitis. This chronic inflammatory disease of infectious origin leads to the progressive destruction of the tissues supporting the teeth, resulting in bone resorption and loss of attachment.

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.
