NewsPrimed and ready to fight: a nematode pheromone arms plants to battle pathogens
New research has found that a previously unrecognized natural compound can provide lasting protection against a broad range of plant pathogens.

NewsTraditional Chinese medicine compound shows promise against ischemic stroke by targeting the gut-brain axis
Researchers have uncovered new evidence that a polysaccharide derived from the traditional medicinal herb Astragalus membranaceus (Huangqi) can protect against ischemic stroke by acting through an unexpected route: the gut.

NewsStudy finds that cognitive decline after omicron infection is largely reversible
Cognitive problems, often described as “brain fog,” are a recognized feature of long COVID, affecting attention, memory, and executive function. Earlier SARS-CoV-2 variants, including the original strain, Alpha and Delta, were associated with persistent cognitive deficits. However, the Omicron variant caused less severe disease, leaving uncertainty about whether cognitive decline ...

NewsEven ancient bacteria possessed intercellular communication structures like humans today
Communication between cells in plants, animals and humans takes place via specialised connecting structures. Researchers have discovered how the regulation of very similar structures was already present in multicellular bacteria.

NewsA full-control strategy could cut simulated mpox infections by 97.8%, suggests mathematical model
Researchers have used mathematical modeling to explore how different interventions could work together to limit Mpox transmission. The model captures Mpox transmission dynamics across two interacting populations: humans and rodents.

NewsA bacterial protein fragment drives tissue fibrosis, but antibody treatment can help
A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell’s quality-control system, researchers found in a new study. Meanwhile, blocking corisin with an antibody impeded the damage.

NewsRECOVER-VITAL clinical trial finds no benefit of extended duration of PAXLOVID for Long COVID
Results from a clinical trial show that the antiviral drug, PAXLOVID, commonly prescribed to treat acute COVID-19, does not have an impact on Long COVID symptoms when compared to placebo.

NewsNew artificial intelligence method to support real-time management of infectious diseases
Scientists used a deep learning artificial intelligence method known as neural posterior estimation (NPE) to study how pathogens evolve, the first time this method has been used with genetic data in a phylodynamic application.

NewsReview explores the presence, fate, and effects of pharmaceutical compounds in soil and air
Pharmaceutical contamination in soil and air has become a critical environmental concern due to its widespread sources, complex behavior, and long-lasting ecological impacts.

NewsResearcher awarded two NIH grants to advance research on antibiotic-resistant infections
The research is focused on developing new strategies to combat two infectious diseases: catheter-associated urinary tract infections (CAUTIs) and invasive Group A Streptococcus skin infections, both of which are increasingly difficult to treat because of antimicrobial resistance.

NewsInfluenza A infection under-reported during 2021 UK pandemic, researchers reveal
Influenza A infections were under-reported during the 2021 UK pandemic, according to research presented earlier this year at MLSFF 2026.

NewsBarley discovery reveals nitrogen cycling pathway that could offer a nature-based solution to fertilizer loss
A new study reveals the presence of a nitrogen cycling pathway in barley that could prove valuable in cutting fertilizer requirements as the cost to farmers rises.

NewsDrought is reshaping the spread of infectious diseases
A review study reveals how drier conditions could make humans and wildlife more vulnerable to certain infectious diseases, even though many parasites and disease-carrying organisms depend heavily on water to survive.

NewsMen more likely to be infected with TB than women
Men are more likely than women to catch tuberculosis, finds a new study. Researchers found that men were more likely than women to already have a TB infection when the study began, but men were not significantly more likely to develop active TB disease than women.

NewsPlant pathologist selected as Fulbright Distinguished Scholar
Heather Kelly, field crops pathologist in the University of Tennessee Department of Entomology and Plant Pathology, has received a prestigious Fulbright Distinguished Scholar Award for two one-month trips to Brazil in 2026 and 2027.

NewsReddit reveals what pregnant women really want to know about the Tdap vaccine
An analysis of Reddit posts about the maternal Tdap vaccine made by pregnant women reveals expectant mothers turning to Reddit to seek advice and reassurance—with fewer outright instances of vaccine hesitation/refusal than has generally been observed for other types of vaccines, according to a study published on August 12, 2026 ...

NewsAncient bacterial signals from cell powerhouses may fuel excessive inflammation
Researchers have discovered that proteins released from mitochondria can activate the immune system in a similar way to invading bacteria, suggesting that remnants of mitochondria’s evolutionary past may contribute to inflammation.

NewsNew study shows how Toxoplasma parasite evolved to adapt to crowded conditions in host cells
How Toxoplasma reshapes its metabolism to keep growing under crowded conditions in a tissue cyst has been unclear. A new study identifies a parasite-specific protein that helps coordinate this response, allowing Toxoplasma to manage oxidative stress.

NewsScientists reconstruct past ocean temperatures from red algae
Researchers have found a new way to reconstruct daily seawater temperatures over a four-month period. The key lies in rhodoliths: nodule-like calcareous structures formed by red algae that occur in oceans worldwide.
