NewsSingle-point testing could miss cases of asymptomatic malaria
Dynamic, fluctuating levels of this parasite in people without symptoms argues against single-point testing to diagnose infections, a new study suggests.
-
NewsNew antibiotics make TB bacterium less pathogenic for humans
Researchers have identified new, antibiotic molecules that target Mycobacterium tuberculosis and make it less pathogenic for humans.
-
NewsMolecular link IDed between gut bacteria and excitatory brain signaling in C. elegans
A new study establishes a molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
-
NewsScientists unlock the secrets of disease-causing fungus Aspergillus fumigatus
A new study demonstrates the pivotal role of the Mitogen-Activated Protein kinase MpkA in both gliotoxin production and self-protection.
-
NewsMicrobial awakening shifts high-latitude food webs as permafrost thaws
A new study shows that fungi are replacing plants as the primary energy source for Arctic and boreal animals.
-
NewsScientists discover how environmental microbes boost fruit fly reproduction
A research group finds that environmental microorganisms enhance oogenesis in fruit flies, increasing the production of germline stem cells and the number of mature eggs in females via hormonal pathways.
-
NewsStudy shines light on resourceful ways bacteria thrive in the human gut
A survey of bacterial genomes highlights the arsenal of enzymes microbes use to produce energy in the oxygen-poor environment of the gut.
-
NewsScientists solve mystery of how predatory bacteria recognizes prey
A decades-old mystery of how natural antimicrobial predatory bacteria are able to recognize and kill other bacteria may have been solved, according to new research.
-
NewsConsuming fermented food natto suppresses arteriosclerosis
A study shows that the intake of natto alters the composition of intestinal microflora in a mouse model, regulating the production of cytokines and chemokines associated with arteriosclerosis.
-
NewsStudy reveals indoor metabolites as key indicators in asthma and allergic rhinitis
Analyzing dust for its chemical fingerprint may be a more reliable and consistent way to assess environmental risk for childhood asthma and allergic rhinitis than studying the complex and variable microbiome, a new study suggests.
-
NewsA high-fat diet could make you vulnerable to harmful microbes, including Covid
A new study demonstrates that high-fat diets negatively impact genes linked not only to obesity, colon cancer and irritable bowels, but also to the immune system, brain function, and potentially COVID-19 risk.
-
NewsStudy reveals clues to how Eastern equine encephalitis virus invades brain cells
An atomic-level investigation of how Eastern equine encephalitis virus binds to a key receptor and gets inside of cells also has enabled the discovery of a decoy molecule that protects against the potentially deadly brain infection, in mice.
-
NewsResearchers reveal how pathogenic bacteria load their syringes
A new study reveals that pathogenic bacteria use molecular “shuttle services” to fill their injection apparatus with the right product.
-
NewsAnts recognize infected wounds and treat them with antibiotics
Matabele ants have developed a sophisticated healthcare system: they can distinguish between non-infected and infected wounds and treat the latter efficiently with antibiotics they produce themselves.
-
NewsResearchers uncover how tiny plastics threaten our soil and health
A new study has found that both nanoplastics and microplastics alter soil microbes and increase antibiotic resistance. Nanoplastics, due to their small size and large surface area, had a more significant impact, even in small quantities.
-
NewsSingle gene could be crucial for persistence in TB bacteria
Researchers have uncovered an important mechanism that allows the tuberculosis (TB) bacterium to persist in the human host for decades.
-
NewsResearchers develop novel solution for Pichia pastoris enzyme production platform
A new study outlines a novel approach in enzyme production, harnessing the untapped potential of cyanobacterial biomass within the P. pastoris platform.
-
NewsMore than 10k viral species found in supraglacial environments
Researchers have revealed more than 10,000 viral species in global supraglacial environments - a 15-fold expansion of DNA viral genomic inventory ever known.
-
NewsResearch reveals ‘best approach’ for detection of maternal sepsis
A new study finds that placental swabs are ‘most effective’ in diagnosing maternal sepsis, findings that were described by research team as ‘very significant’ in helping choice of treatment for infections.
-
NewsArtificial intelligence predicts the influence of microplastics on soil properties
Scientists used machine learning to reveal how different characteristics of soil microplastics can significantly alter soil properties.
