NewsBacterial scents behind oak tree decline may be luring deadly beetles
The deadly decline of Britain’s native oak trees may be driven by an unexpected accomplice: their own smell. Scientists have discovered that trees affected by Acute Oak Decline (AOD) emit distinct odours that are highly attractive to the beetle Agrilus biguttatus, a key contributor to the decline.

NewsWomen are three times more likely than men to get severe long COVID: Here’s why
Researchers have identified a distinct immune signature in female long Covid patients versus male patients. They found evidence of ’gut leakiness’ in the women patients, including elevated blood levels of intestinal fatty acid binding protein, lipopolysaccharide, and the soluble protein CD14 — all signs of gut inflammation that can then trigger further systemic inflammation.

NewsEveryday levels of antibiotics in the environment may accelerate the global spread of resistance, new study finds
A new study shows that even very small amounts of antibiotics that commonly appear in soil, rivers, wastewater, and agricultural runoff may significantly accelerate the spread of antibiotic resistance genes among bacteria.

NewsNew blueprint for nature’s carbon-capturing nanomachines revealed
Researchers have uncovered how bacterial organelles assemble, opening new routes for bioengineering and climate innovation. The team has unveiled the most detailed picture yet of how bacteria construct microscopic compartments known as carboxysomes – natural nanomachines that play a vital role in capturing and converting carbon dioxide (CO₂).

NewsExperts urge continued hepatitis B vaccine birth doses for newborns
In a new commentary, leading experts urge that all newborns in the United States continue to receive the first dose of hepatitis B vaccine within 24 hours of birth. Hepatitis B vaccines are safe and effective with over one billion doses administered worldwide.

NewsPredicting the development of biological communities in different kinds of ecosystems
Researchers tested a mechanistic consumer-resource model and confirmed its high predictive capacity. Using the model, the researchers refined current rules on the coexistence of species, too. Their findings can be applied to any situation in which communities of organisms compete for resources.

NewsNew study reveals microbial network restructuring mitigates long-term soil carbon emissions from warming
Scientists conducted a decade-long study that uncovered a previously unrecognized buffering mechanism in subtropical forest soils mitigating the effects of climate warming.

NewsFungal oxalic acid dampens plant immunity through targeting CERK1 deamidation
Scientists found that oxalic acid was a critical virulence factor for both S. sclerotiorum and B. cinerea during their infections of Arabidopsis plants. Further characterizations revealed that OA-mediated virulence in these fungal pathogens was contingent on CERK1.

NewsNew DNA analysis approach could transform understanding of disease evolution
By adapting techniques originally used to study ancient DNA from archaeological specimens, researchers were able to recover genetic information from nearly century-old medical samples.

NewsAvian flu halves South Georgia’s breeding elephant seal population
South Georgia’s breeding population of female southern elephant seals (Mirounga leonina) may have been halved by highly pathogenic avian influenza virus (HPAIV), finds new research. These losses may threaten the security of the island’s breeding population.

NewsThe link between the gut microbiome and autism is not backed by science, researchers say
There’s no scientific evidence that the gut microbiome causes autism, a group of scientists argue in an opinion paper. They warn that conclusions that supported this hypothesis are undermined by flawed assumptions, small sample sizes, and inappropriate statistical methods.

NewsManganese is Lyme disease bacterium’s double-edged sword
For decades, Lyme disease has frustrated both physicians and patients alike. Caused by the corkscrew-shaped bacterium Borrelia burgdorferi, the infection, if left untreated, can linger for months, leading to fever, fatigue and painful inflammation. Source: U.S. Centers for Disease Control and Prevention This digitally colorized scanning electron microscopic ...

NewsImaging reveals bacterial symbionts in the ovaries of tiny, aquatic crustaceans
Researchers have imaged a heritable form of bacterial symbiosis inside the reproductive system of tiny crustaceans known as ostracods. Bacteria from the genus Cardinium live inside the egg cells and tissues of ostracod ovaries, transmitted from mothers to offspring.

NewsScientists find way to find the gut microbiome into a longevity factory
A team of researchers has found a way to turn the bacteria living in the digestive tracts of animals into factories that can produce compounds that promote longevity in their hosts—showing a potential new drug development strategy.

NewsRainfall and temperature shape mosquito fauna in Atlantic Forest bromeliads, including malaria vectors
Results from a study of mosquito larvae conducted in a natural area in the municipality of São Paulo (Brazil) may help estimate the effects of climate change on disease transmission risk in the biome.

NewsHigher methane emissions from warmer lakes and reservoirs may exacerbate worst-case climate scenario
Emissions of the greenhouse gas methane from lakes and reservoirs risk doubling by the end of the century due to climate change according to a new study. This in turn could raise Earth’s temperature more than suggested by the UN climate panel IPCC’s current worst-case scenario.

NewsStudy finds high rates of antibiotic-resistant bacteria in raw milk
Raw cow and sheep milk is frequently contaminated with antibiotic-resistant bacteria that could pose a threat to human and animal health, reports a new study.

NewsScientists tie lupus to a virus nearly all of us carry
The Epstein-Barr virus is directly responsible for commandeering what starts out as a minuscule number of immune cells to go rogue and persuade far more of their fellow immune cells to launch a widespread assault on the body’s tissues, a study has shown.
