NewsNew antibiotic attacks bacteria in never-before-seen way
Scientists have discovered a new antibiotic that works in a never-before-seen way and may be the next frontliner in the fight against drug-resistant superbugs.

NewsWhy plastic lingers: Water chemistry slows nature’s cleanup
In a new study designed to mimic real environmental conditions, researchers found that the chemical makeup of natural waters significantly delays the breakdown of polystyrene, a common plastic used in packaging and food containers. Because sunlight cannot effectively initiate the degradation process, microbes cannot finish the job.

NewsThe evolution of individual species can shape entire species communities
A study demonstrated that the evolution of a single species can alter the composition of an entire species community. The study monitored a microbial community composed of 23 bacterial species for four years. Researchers analysed the community’s species composition and changes in bacterial genomes.

NewsBiochar and beneficial microbes team up to restore polluted soils and boost crop growth
A new review examines how biochar-immobilized microbes can help clean contaminated soils, improve soil health, and support crop growth. By analyzing evidence from 92 published studies, the authors provide a data-driven overview of how this technology works and what is needed to bring it closer to practical use on farms.

NewsStudy finds common infection does not increase risk of recurrent preterm birth
A new study has found that the common sexually transmitted infection, Mycoplasma genitalium, also known as MGen, does not appear to increase the risk of recurrent preterm birth. Earlier research suggested that certain Mycoplasma species might contribute to preterm labor, but those studies were limited.

NewsResearcher efforts to reproduce corals shared with TV cameras
Scientists at Nova Southeastern University are sharing a rare look at a marine mission that aims to pump life back into coral reefs. Researchers waiting for coral-spawning hope the project will be a game-changer in the South Florida ecosystem.

NewsWarming may weaken biochar’s climate benefits in cropland soils, global study finds
Researchers found that warming significantly increased carbon dioxide emissions from soils treated with biochar by an average of 77%. The effect was especially strong in croplands, where emissions increased by 117.5%, compared with 30.9% in forest soils.

NewsFirst-in-human clinical trial shows promising results for new Lassa fever vaccine
Researchers have reported encouraging results from an early clinical trial that tested a new dual vaccine against Lassa fever and rabies. The study found that the vaccine was safe and induced immune responses against both viruses. There are currently no vaccines against Lassa fever on the market.

NewsPlants could be used to grow medicines in space, study shows
Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand. Researchers developed a simple method to grow and repeatedly harvest plant virus-based pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste.

NewsDolichol biosynthesis conserved across eukaryotes, not limited just to humans
Researchers say a newly proposed three-step “detour” pathway for making dolichol may be more universal than scientists realized. Experiments in yeast suggest eukaryotes may rely on overlapping biochemical pathways, including the evolutionarily conserved “detour” and evidence of a possible “backup route,” to produce a molecule essential to life.

NewsWhat dental calculus can tell us about the oral microbiomes of ancient Japan
Microbe DNA from ancient dental calculus offers insights into the past oral microbiomes of the Japanese people, including the phylogeny of the periodontal disease-associated archaeon, Methanobrevibacter oralis.

NewsAntibiotics drive resistance in waterways - even after they break down
Antibiotics continue to drive resistance to bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first time.

NewsDigital model guides cleaner biohydrogen production
A research team has developed an enzyme-aware digital model that explains why hydrogen-producing microbes often struggle to grow fast and generate hydrogen efficiently at the same time. The study reveals how limited enzyme resources shape the balance between cell growth, by-product formation, and hydrogen generation.

NewsShiga-producing E. coli infections are becoming more resistant to antibiotics
A new study indicates resistance to antimicrobial agents is rising among human infections with Shiga toxin–producing Escherichia coli bacteria.

NewsTime for an AI checkup: Flaw found in machine learning for sepsis treatment
Researchers found a flaw in many peer-reviewed studies using the AI method known as reinforcement learning as a theoretical guide for the treatment of sepsis. If these flawed systems for sepsis treatment were deployed in a healthcare setting, they would recommend either overtreatment or undertreatment in nearly half of patient states.

NewsMost cases of HIV persistence in blood following treatment explained by defective copies of the virus
A study based on blood samples strongly suggests that most persistent cases of viral detection, despite ideal HIV drug therapy, are not due to virus transmission or a rebound of active disease.

NewsScientists probe links between green space exposure, mental health and the nasal microbiome
Researchers recently studied associations among green space exposure, mental well-being, and the nasal microbiome—the microbes in a person’s nose. The analysis showed correlations among microbial signatures, time spent outdoors and positive mental well-being.

NewsFood insecurity linked to gut microbiome changes in children
A new study shows that food insecurity may leave a measurable impact on the gut microbiome of children. Children in food-insecure households had different gut microbiome profiles, including higher levels of Sutterella, which has been linked to poor dietary quality and intestinal inflammation.

NewsHow are chloroplasts communicating with the nucleus? Bacterial enzymes show the way
By utilizing bacterial enzymes that cleave heme molecules at different sites, researchers have developed a method to dissect phytochrome-dependent light and heme retrograde signaling pathways in plants, which have previously been difficult to discuss separately.

NewsNew study highlights maternal-fetal TORCH infection risk
Researchers have assessed long-term trends in TORCH infections in India, a region where reliable data have been lacking. TORCH includes pathogens that cause toxoplasmosis, rubella, cytomegalovirus (CMV), herpes simplex virus and other infections.
