NewsGut fungi may hold the key to treating asthma worldwide
Two new studies reveal that certain species of fungi in the gut play a key role in the development of immune dysregulation and some pediatric allergic diseases — and may be promising targets for new therapies.

NewsNatural symbiosis: How plants and microbes share vital nutrients in fragile ecosystems
Researchers using stable isotope labelling to investigate how different forms of nitrogen are used by plants and microbes in alpine heath environments found that plants and microbes use distinct strategies to access this critical nutrient.

NewsUnsafe water still drives global diarrheal disease burden
A new study, analysing data from the Global Burden of Disease 2021 database, found that deaths and disability-adjusted life years linked to unsafe water have declined sharply over the last three decades. Nevertheless, the burden remains concentrated in low socio-demographic index regions.

NewsMicrobes reveal how tillage shapes soil carbon storage
A new study on maize fields in Jilin Province, China, found adding organic carbon sources on top of straw had different effects on the organic carbon in the topsoil in comparison to the subsoil.

NewsGlobal port microbiomes reveal hidden biosecurity signals
By analyzing more than 16 million 16S rRNA gene sequences from 1,045 port water samples collected in 23 cities across five continents, a study has found clear biogeographic patterns, a core set of dominant bacterial genera, and widespread potential pathogens.

NewsPhylogenetic analysis reveals ten new species of Inocybe mushrooms
New taxonomic and phylogenetic investigation of Inocybe mushrooms reveals ten new species, one newly discovered in the Gaoligong Mountains, China.

NewsOrdinary enzyme evolves into a ‘control switch’ revealing a new weak spot in tuberculosis
A protein that acts as a ‘control switch,’ preventing Mycobacterium tuberculosis from accessing the energy sources it needs to survive, has been identified by researchers. The discovery points to a specific vulnerability in the bacterium that could be targeted by new TB treatments.

NewsHow cyanobacteria developed photosynthetic membranes over the course of evolution
New research analyses hundreds of cyanobacterial genomes to understand the origin of thylakoids, the internal membranes involved in photosynthesis.

NewsTea’s molecular shield against anthracnose
Researchers investigating inducible immune mechanisms activated by tea plants after pathogen infection said the findings show that tea anthracnose resistance is not simply a matter of possessing a resistance-related gene, but of how strongly and rapidly the plant activates its defense network.

NewsWhy do viruses not kill the mosquitoes that transmit them?
A new study reveals the mechanism that allows viruses such as chikungunya or dengue to be harboured in mosquitoes without killing them, thus facilitating their transmission.
-
NewsProtective human antibodies target West Nile and related viruses
New research defines vulnerable sites on West Nile virus that could inform vaccine development, and highlight antibody candidates with prophylactic and therapeutic potential. They may also guide interventions for a wider group of encephalitic orthoflavivirus infections.

NewsSoil bacteria reveal hidden arsenic stress in brick kilns
Researchers collected soils from a shut-down brick kiln area. As arsenic levels increased, bacterial richness and diversity declined, while arsenic-tolerant groups became more abundant. The study also found that bacteria strengthened stress-response pathways and upregulated arsenic-resistance genes.

NewsA two-pronged vaccine approach to prevent genital herpes
Researchers have taken a significant step toward a genital herpes vaccine that in preclinical models prevented infection. This study extends the original “prime and pull” approach by developing a new nanoparticle that effectively induces local immunity.

NewsTracking melanoidins to improve food-waste biogas recovery
Higher pretreatment temperatures in food-waste biogas recovery can promote Maillard reactions, generating melanoidins. A study shows that melanoidins increase with hydrothermal temperature and inhibit methane production by disrupting methanogenic microbial communities.

NewsAntibiotic use for uncomplicated diverticulitis remains widespread despite guideline shifts
A retrospective cohort study found that antibiotic prescribing rates for outpatient cases of uncomplicated diverticulitis remain above 95%, despite guidelines from 2015 recommending more selective use.
-
NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.
-
NewsCaught in the act: A gene jumps into the void
Self-splicing introns are a special group of jumping genes. It is more difficult for a gene to jump into another cell or another species. Until now, it had been assumed that, for this to happen, the jumping genes travelled as ‘hitchhiker’ in the genomes of plasmids or viruses, but researchers have made a surprising observation.

NewsLow risk of global spread of Ebola disease, analysis suggests
Researchers identified and analysed all known Ebola disease cases outside Africa to assess the risk of undetected Orthoebolavirus transmission outside Africa and to put it into context with possible border and travel policies.

NewsHow H5N1 bird flu hid unrecognized for weeks in dairy cattle
A new study reveals why H5N1 influenza infection looked so different in dairy cows, offering a framework for spotting new host species quickly. Instead of affecting the lungs, it caused severe infection in the cows’ udders, largely sparing the lungs.

NewsOropouche virus has already infected more than 5 million people in Brazil, study suggests
The recent Oropouche virus outbreak in 2023 has drawn attention in Brazil and other Latin American countries because of its scale and rapid spread. Researchers estimate that since 1960, the virus has infected approximately 9.4 million people in Latin America and the Caribbean.
