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.

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.

NewsTesting AI against public health’s existing tools
A new study found that AI chatbots made vaccine-hesitant parents more likely to say they would vaccinate their children against HPV, but did not outperform materials from government health agencies, whose effects also lasted longer.

NewsAll-new lab in Kenya fills critical gap in wildlife health
Conservation stakeholders gathered to celebrate the official opening of the Laboratory in Northern Kenya (LiNK), an all-new veterinary diagnostic lab designed to fill a critical need for accessible diagnostic infrastructure in the remote region.

NewsAccelerating chikungunya vaccine development in Africa: Launch of the ACT-CHIK Project
Funded by the Global Health EDCTP3 Joint Undertaking, a new €15.3 million project coordinated by Institut Pasteur brings together seven partners across four continents to advance clinical trials and prepare for the manufacturing of a chikungunya vaccine in Africa.

NewsEurope’s crops under threat: €6 million project launches to tackle rising plant pest crisis
The University of Warwick leads a European consortium to build the first platform capable of coordinating Europe’s response to devastating agricultural and forest pest invasions. The project will give plant health authorities the ability to model and optimise pest control strategies across the entire agri-value chain.

NewsResearch team awarded NIH grant to study early immune determinants of human tuberculosis infection
A research team was awarded a 5-year, $3.8 million grant to study early immune responses in the lung and how they influence tuberculosis infection outcomes. The program focuses on how lung immune cells called macrophages influence the earliest stages of tuberculosis infection.

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.

NewsNew study provides insights into the control of photosynthesis
Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. A crucial protein interaction at the interface between the two photosystems I and II controls the photosynthetic machinery.

NewsDrug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.

NewsGene swapping helped build the planet’s decomposers
Researchers have reconstructed the deep history of osmotrophic specialization in eukaryotes. Their findings suggest that four groups of eukaryotes which have specialized in osmotrophy first arose between 720 million and 1 billion years ago and that they share a toolkit of genes involved in osmotrophic functions.

NewsInfections are major ‘health hazard’ for people with diabetes
Infections should be considered a “health hazard” in people living with diabetes, with experts warning that current clinical guidelines fail to reflect a substantial but under-recognised burden of illness, hospitalisation and death. People living with type 1 diabetes, type 2 diabetes and prediabetes face higher risks of infection compared to those without diabetes.

NewsIndigenous mushroom transforms agricultural waste into food
An edible, seasonal mushroom in Eastern Nigeria has nutritional and therapeutic potential but is poorly researched. New research suggests that domestication of Lentinus squarrosulus using waste materials, specifically sawdust, could boost food production and provide employment opportunities for farmers and small businesses.
