News'Failed drug' could offer new approach to Epstein-Barr virus and resulting diseases
Researchers have found that the Epstein-Barr virus triggers infected cells to ramp up the production of an enzyme known as IDO1, a discovery that offers a promising starting point for putting the brakes on EBV.

NewsSea urchin epidemic spreads to Indian Ocean, threatening coral reefs
Researchers have identified the pathogen responsible for the epidemic which is killing sea urchins in the Red Sea, and now threatens entire populations of sea urchins across the Red Sea and Indo-Pacific.

NewsMilk samples from the 1940s shed new light on antibiotic resistance
Researchers found the samples from before the antibiotic era were resistant to the antibiotic tetracycline.

NewsMistaken identity cleared up of foodborne pathogen causing severe symptoms in children
A novel real-time PCR method might become a diagnostic tool targeting emerging bacterium responsible for food poisoning outbreaks.

NewsFarm wastewater modelling shows footbaths are source of antimicrobial resistance
New research has mapped wastewater flows on farms and revealed where spikes in antibiotic resistant bacteria in slurry occurs, showing that water from copper and zinc footbaths used by dairy animals can cause fluctuations.

NewsVirocells: How the ‘home’ environment influences microbial interactions
Research into ocean virocells - bacteria infected by viruses, thus forming a new organism - has yielded fascinating new insights about how this merger of microbes affects, and is affected by, real-world surroundings.

NewsBiotech companies leverage novel tools to develop drugs for RSV
Reporter structures that can be introduced into cells for use in drug screening assays emit fluorescent or bioluminescent light at different intensities when RSV genes are inhibited by the potential antiviral agents being tested.

NewsMitochondrial phosphate carrier plays an important role in virulence of Candida albicans
Scientists have found that the lack of MIR1 gene, which encodes mitochondrial phosphate carrier, can lead to severe virulence defects in Candida albicans.

NewsAntibiotic ‘Velcro’ gives bacteria a sticky situation
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface - scientists have now mapped how this bond is formed.

NewsSewage overflows linked to increase in gastrointestinal illnesses
A new study suggests the risk of people developing acute gastrointestinal illness is significantly higher in Massachusetts communities that border the Merrimack River in the four days following extreme combined sewer overflows.

NewsCentury-old vaccine protects type 1 diabetics from infectious diseases
Research shows that the 100-year-old Bacillus Calmette-Guérin (BCG) vaccine, originally developed to prevent tuberculosis, protects individuals with type 1 diabetes from severe COVID-19 disease and other infectious diseases.

NewsMimicking infection in pregnant mice provokes persistent changes in juvenile brains
No parent wants to risk their child having a serious infection, least of all while still in the womb, but did you know that the immune response to a viral infection during pregnancy could also affect the development of the unborn offspring? Scientists from Harvard University in ...

NewsAncient viral DNA in the human genome linked to major psychiatric disorders
New research led by King’s College London has found that thousands of DNA sequences originating from ancient viral infections are expressed in the brain, with some contributing to susceptibility for psychiatric disorders such as schizophrenia, bipolar disorder, and depression. Published in Nature Communications, the study was part-funded ...

News HPV testing for cervical cancer may be safe at longer intervals than recommended by current guidelines
The risk of detecting cervical precancer eight years after a negative HPV screening was found to be similar to the risk after three years (the commonly recommended screening interval) after a negative cytology screening.
