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.

NewsPreviously unknown viruses discovered in groundwater
Researchers have created a comprehensive picture of viral diversity and function in a groundwater system. They identified over 257,000 viral operational taxonomic units, i.e. viruses at species level, 99 % of which were previously unknown.

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.

NewsResearchers urge focus on child obesity and gut health to reduce risk of diabetes
Researchers are calling for more study of obesity, gut bacteria and metabolic conditions that arise in childhood and adolescence, with an eye to curbing the global rise of type 2 diabetes.

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.

News A fungus living in our body can make melanoma more aggressive
A study has for the first time established the mechanism by means of which the Candida albicans fungus makes melanoma more aggressive. It activates several signalling pathways in the melanoma cells, creating an environment that helps to reprogram angiogenesis and metabolism.

NewsBBSRC-backed spin-out launches rapid DNA air sequencing technology
New spin-out, Agnos Biosciences, has launched AirSeq, a rapid DNA air sequencing technology to transform pathogen detection across health, food and biosecurity. It brings to market a powerful new approach to detecting biological threats in the air.

NewsScientists demonstrate first-ever single-shot HIV vaccine neutralization success
Scientists have developed an HIV vaccine candidate that achieves something never before observed in the field: inducing neutralizing antibodies against HIV after a single immunization in nonhuman primates.

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.

NewsPlants influence the composition and function of their surrounding microbiome to suit their needs
An investigation into plant–microbe interactions at the genetic, metabolic and physiological levels revealed that 203 bacterial gene sequences were strongly shaped by the host plant, for example through their metabolic products. One bacterial genus was found to enhance root development even in nitrogen-limited soils.

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.

NewsRisk for Lyme disease in Ohio is equal to Connecticut, study shows
The risk for being bitten by a tick infected with bacteria that cause Lyme disease is as high in Ohio as it is for those living in Northeast states that have dealt with Lyme disease for over 50 years, according to a new study.

NewsGenes from corn’s wild ancestor change soil microbial community, improve sustainability
Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction, according to new research. It’s the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria.

NewsWhy aren’t more older adults getting flu or COVID-19 shots?
This winter’s brutal flu season isn’t over, and COVID-19 cases have risen recently too. But a new poll taken in recent weeks shows that vaccination against both viruses lags among people 50 and over, and the US survey reveals key reasons why.

NewsHigh consumption of ultraprocessed foods may be linked to cancer survivors’ risk of death
Cancer survivors who consumed higher amounts of ultraprocessed foods as part of their diet had a significantly increased risk of both all-cause and cancer-specific death, a new study shows.

NewsWHO calls for mental health to be central to neglected tropical disease care
A major new World Health Organization publication sets out, for the first time, a practical, evidence-based package of care to address the mental health impacts of neglected tropical diseases (NTDs) and the stigma that can prevent people from seeking care and participating fully in society.

NewsLab-grown algae removes microplastics from water
Scientists have applied a revolutionary strain of algae toward capturing and removing harmful microplastics from polluted water. The aim is to repurpose the collected microplastics into safe, bioplastic products such as composite plastic films.

NewsCommon bacteria discovered in the eye linked to cognitive decline
Chlamydia pneumoniae can linger in the eye and brain for years and may aggravate Alzheimer’s disease. Research suggests this bacterium can amplify Alzheimer’s disease and points to potential interventions including inflammation-limiting therapies and early antibiotic treatment.
