NewsGenetic ‘bonus material’ makes the gut bacterium Segatella copri oxygen-tolerant
Researchers have found that some strains of the gut bacterium Segatella copri possess bonus material that makes them more oxygen tolerant. The presence of the molecular regulator OxyR is crucial for this. The team discovered that strains carrying OxyR are particularly prevalent in industrialized regions of the world.

NewsResearchers uncover hidden health risks from urban airborne microbes
Researchers have discovered that seemingly insignificant microbial components in the air, including bacteria, fungi, viruses and cellular debris, pose a long-overlooked health hazard. Bacterial endotoxins can trigger inflammatory responses in the human respiratory system in nearly 20% of cases.

NewsResearchers identify potential new route for antimalarial drug design
Researchers have uncovered a promising new potential target for drug discovery. The team focused on an enzyme called aminopeptidase P (PfAPP) from Plasmodium falciparum, the parasite responsible for the most severe form of malaria in humans.

NewsFungi utilize ancient antimicrobial proteins to attack hosts and their microbiomes
An international research team has discovered the surprising evolutionary origin of fungal effector proteins: molecules that pathogens use today to infect their hosts appear to have evolved from ancient antimicrobial proteins.

NewsPolymer ‘bristles’ could help repel proteins — and germs — from surfaces in medical settings
A non-toxic coating made of polydimethylsiloxane prevents proteins from sticking to surfaces — potentially offering a new tool in the fight against hospital-acquired infections.

NewsDairy farms in California may transmit H5N1 virus through multiple sources
A new study suggests that avian influenza (H5N1) is transmitted through multiple, previously unknown sources on dairy farms and that some H5N1 positive cows do not show clinical signs of infection.

NewsNew research finds that almost all plant-based meat alternatives contain mycotoxins
New research into plant-based food and drinks has found a prevalence of mycotoxins – naturally occurring poisonous compounds produced by fungi - in hundreds of vegetarian and vegan products.

NewsNutrient imbalance may drive coral disease more than heat stress, new study suggests
New research shows that an imbalance of nutrients in seawater can cause coral disease – possibly to a greater extent than that from heat stress of warming oceans. Disruption of the delicate nutrient balance of the sea can destabilise microbial communities that live in harmony with corals.

NewsEarly life on Earth relied on a surprisingly scarce metal
A new study shows that 3.4 billion years ago, life on Earth relied on a metal called molybdenum, despite its limited availability at the time. It is the first to trace molybdenum’s use this far back in time.

NewsCaesarean birth: sex-specific effects on the microbiota
A research team investigating microbial colonisation in early life set out to understand how delivery mode and sex interact over the course of development, and whether this interaction could affect susceptibility to intestinal diseases such as colitis in adulthood.

NewsClimate change increases spillover risk of rodent-borne arenaviruses
Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, according to an early risk projection model that incorporated climate projections, shifting rodent populations and the risks of human infection.

NewsModerate UV light is best to boost the vitamin D content of edible mushrooms, study finds
Researchers have discovered that moderate ultraviolet (UV) light exposure is best when the technique is used to enhance vitamin D₂ in edible mushrooms. Excessive exposure leads to nutrient degradation or a plateau effect, they found.

NewsNew study shows cranberry juice may boost UTI antibiotics
Researchers recently exposed lab-grown strains of pathogenic Escherichia coli to cranberry juice. Preliminary findings suggest that compounds in the juice re-sensitize resistant strains to antibiotic treatment.

NewsResearchers advance phage therapy in fight against antimicrobial resistance
Scientists have uncovered how Mycobacterium abscessus can evade bacteriophage therapy, and demonstrated a combination strategy to overcome this resistance, offering a pathway towards more effective and durable treatments.
-
NewsNovel wheat hybrids increase resistance to major fungal disease by up to 70%
A new experimental study has identified a novel genetic locus in a common agricultural weed that provides significant resistance to Fusarium Head Blight (FHB) and has now been successfully transferred into wheat to produce FHB resistant hybrids.

NewsProviding food baskets to people with tuberculosis is cost-effective and could avert over 100,000 deaths annually in India
Undernutrition is the single greatest modifiable risk factor for tuberculosis (TB). Researchers found that providing food baskets to people with TB and their households may save tens of thousands of lives annually in India if implemented at scale.

NewsWith large DNA fragment assembly, scientists can design microbes that produce countless complex products
A review demonstrates that scientists can now reliably build and combine very large pieces of DNA, making it much easier to redesign microbes such as yeast and bacteria to act as efficient “cell factories.”
-
NewsCan new research findings help overcome challenges to malaria treatment?
A new study may help overcome challenges to the treatment of malaria. The research is based on a strategy that targets an enzyme specific to the parasite, Falcipain-2 (FP2), which is essential for parasite survival and growth within the host.

NewsGut microbes actively support immunity in people living with HIV
A new study shows that gut microbes help bolster immunity in people living with HIV – and that, one day, these microbes may be harnessed to protect this population from infections driven by immune deficiency.

News‘Living plastic’ activates and self-destructs on command
Living plastics that self-destruct on command incorporate activatable, plastic-degrading microbes alongside the polymers. The latest study used two bacterial strains that worked together and completely broke down the material within just six days, without making microplastics.
