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.

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.

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.

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.

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.

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.

NewsArctic plant–fungal partnerships are surprisingly flexible in a warming world
A new study suggests that Arctic fungi appear to form opportunistic partnerships with whatever plant hosts are available, rather than maintaining exclusive relationships. This flexibility may help both plants and fungi cope with rapid environmental change.
