NewsPartners launch development of a portable rapid diagnostic system for Ebola virus disease
Professor Yasutoshi Kido of the Graduate School of Medicine, Osaka Metropolitan University (OMU), in collaboration with K.K. DNAFORM and the National Institute for Biomedical Research (INRB) of the Democratic Republic of the Congo, is developing a portable rapid diagnostic system for Ebola virus disease (EVD) caused by Bundibugyo virus (BDBV). ...

NewsROS–Jak2/Stat3 signaling drives HBV-induced liver inflammation
Scientists investigated the mechanisms underlying HBV-induced liver inflammation and identified a reactive oxygen species (ROS)-dependent signaling cascade that activates the Jak2/Stat3 pathway, thereby triggering hepatic inflammatory responses.

NewsNovel pathway suggests gut microbiome could be harnessed to lower blood pressure
The gut microbiome could potentially be harnessed to help lower blood pressure, according to a new study that identifies a previously unknown gut microbiota-bile acid signaling pathway targeting hypertension.

NewsSweeteners shown to slow growth of important gut bacteria in lab tests
Researchers have shown how commonly-used sweeteners slow the growth of certain gut bacteria. One sweetener in particular – combined with the anti-depressant duloxetine - significantly impaired two important gut bacteria linked to regulating blood sugar and gut health.

NewsNew class of fungi named after the King of Sweden
Researchers have discovered a completely new fungal species, which they chose to name after the King of Sweden. It is the first known representative of a new class of fungi that will be called Semicentenialomycetes.

NewsAntibiotic resistant gene found in Australian soil
A new study reveals a hidden source of antibiotic resistance. The novel gene found in contaminated freshwater NSW sediment provides bacteria with resistance to polymyxin - a critical last line antibiotic, used when others stop working.

NewsConnection between forests and rivers strengthens amphibians’ microbiome and protects them against a lethal fungus
A study indicates that a frog’s resistance to a fungus that has decimated hundreds of amphibian species worldwide is due not only to its genes, but also to the beneficial bacteria living on its skin and to the organization of its surrounding landscape.

NewsLow carbon dioxide levels improve microbial production of biodegradable plastic
In an innovative gas fermentation process, reducing concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic, poly[(R)-3-hydroxybutyrate]. The study provides a promising strategy for sustainable carbon recycling and efficient CO2 utilization.

NewsScientists find hidden individuality in viral infections
An international team of researchers developed a new way to uncover hidden differences in how viruses infect and destroy individual microbial cells—solving a biological puzzle that has persisted for more than 80 years.

NewsBacteria form ‘herds’ to survive predators, offering fresh insight into Earth’s carbon cycle
Researchers have discovered that tiny photosynthetic bacteria band together into protective ‘herds’ when attacked by predators – a survival strategy that could also influence how carbon is stored in the world’s waters.

NewsMystery of why some toads survive deadly fungus revealed
The mystery of why some populations of amphibians recover following outbreaks of a deadly fungus has been solved in a new study. Researchers looked at peptides that the toads secreted from their skin – a key part of their immune defence.
