NewsNew insights into Cortinarius: Novel taxa from subtropical China
Scientists have described one new section, six new species, and report one new name, one new combination, and one new record of Cortinarius from subtropical China. All new taxa are supported by phylogenetic data and morphological observations.

NewsStudy finds cases of ME/CFS increase following SARS-CoV-2
New findings suggest that infection with SARS-CoV-2, the virus that causes COVID-19, may be associated with an increase in the number of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) cases.

NewsHow fungi strengthen their defenses - and how we could break through them
A research team has discovered that the enzyme Mod5 in the fungus Aspergillus fumigatus plays an important role in the modification of fungal tRNA and helps confer temporary antifungal resistance.

NewsRoute of entry for Semliki Forest virus into the brain revealed, yielding brain cancer treatment hope
Researchers have shown that the Semliki Forest virus enters the central nervous system by first entering the cerebrospinal fluid and binding to a specific cell type before penetrating deeper into the brain, potentially tagging the virus as an agent for treating brain cancer.

NewsGut bacteria in a chemical tug-of-war with the body
Researchers have identified a clever trick the body uses to keep gut microbial influence on the metabolism in check. In the intestines, the body modifies the microbial bile acids into a new family of derivatives, called BA-MCYs, using an enzyme named VNN1.

NewsManure management in China cuts river antibiotic pollution but raises groundwater contamination risks
A study of antibiotic pollution patterns in China’s water systems over the past decade found a 59% decrease in antibiotic pollution in rivers, primarily due to reduced direct manure discharge, but antibiotic leaching into groundwater has increased by 15%.

NewsNew insights offer hope for developing antiviral therapeutics targeting mpox
New research provides novel perspectives on the biological function of G4s in the lifecycle of MPXV and offer potential avenues for developing antiviral therapeutics targeting mpox prevention and treatment.

NewsScientists explain how a compound from sea sponge exerts its biological effects
Girolline, a compound extracted from the sea sponge Pseudaxinyssa cantharella, has been investigated for possible antitumor effects and also found to have anti-malarial effects. Now researchers have a better idea of how it works.

NewsSyringe-wielding germs could crack antimicrobial resistance crisis
Friendly germs armed with their own biological syringes and poisons could hold the key to overcoming the antimicrobial resistance crisis, according to a new study.

NewsWrong place, wrong time: Why Zika virus hijacks a protein needed for brain growth
A new study shows that the Zika virus hijacks a host protein called ANKLE2, which is important for brain development, to assist its own reproduction. Because Zika can cross the placenta, this can have disastrous consequences in pregnancy.

NewsPet dogs often overlooked as spreader of antimicrobial-resistant Salmonella
Household dogs are an overlooked transmission point for zoonotic pathogens such as nontyphoidal Salmonella, which can cause diarrhea, fever and abdominal cramps, with some infections potentially having life-threatening complications.

NewsDangerous bacterial biofilms have a natural enemy - thanks to stressed plants
Scientists have discovered a chemical that plants produce when they’re stressed prevents biofilm from forming. The breakthrough offers potential advances in healthcare as well as preventing equipment corrosion in industrial settings.

NewsSoil fungus mechanism yield slow but effective control of nematodes
For the first time, researchers have been able to understand how the soil fungus 𝘔𝘰𝘳𝘵𝘪𝘦𝘳𝘦𝘭𝘭𝘢 𝘢𝘭𝘱𝘪𝘯𝘢 eliminates nematodes with the help of natural products and could thus also help agriculture.
-
NewsT cells’ capability to fully prevent acute viral infections opens new avenues for vaccine development
Scientists have discovered that T cells—white blood cells that can destroy harmful pathogens—can completely prevent viral infection, to an extent previously thought only possible due to neutralising antibodies.
-
NewsStudy uncovers new pathway controlling levels of body fat and cholesterol
Beneficial gut microbes and the body work together to fine-tune fat metabolism and cholesterol levels, according to a new preclinical study.

NewsBacteria linked to successful restoration of elkhorn coral colonies
Coral restoration should prioritize shallower depths with faster currents in low-nutrient environments to promote a healthier microbial community, a new study suggests.
-
NewsSmall antibody offers broad protection against influenza
Researchers have discovered an antibody-like molecule that can protect mice from various influenza viruses. The findings could pave the way for new treatments and the development of broader influenza vaccines.
-
NewsStudy reveals root-lesion nematodes in maize crops - and one potential new species
A new study has lifted the lid on five species of root-lesion nematodes living in maize crops across New Zealand - and suggested the existence of a hitherto-unsuspected cryptic species.

NewsFeeding your good gut bacteria through fibre in diet may boost body against infections
Researchers who used computational approaches to analyse the gut microbiome composition of over 12,000 peoplefrom their stool samples found that a person’s microbiome ‘signature’ can predict whether their gut is likely to be colonised by Enterobacteriaceae.
