NewsSolving by-product problem paves way for bacterium to produce chemicals
An engineering technique that domesticates Vibrio natriegens to overcome the production of an unwanted by-product could pave the way for the bacterium to become a producer of chemicals, researchers have found.

NewsBioleaching bacteria exploit cracks to form biofilms on REE rocks
Bioleaching bacteria home in on and around grooves and crevices in rare earth element-bearing rocks and form biofilms, potentially offering a route to making the process more efficient, a new study shows.

NewsSingle hepatitis E mutation renders sofosbuvir therapy ineffective
A single mutation of the hepatitis E virus has been shown to cause treatment with the hepatitis C drug sofosbuvir to become much less effective, according to a study that provides new insights for future drug development.

NewsFeral cats shed more toxoplasmosis parasites in areas densely populated by humans
A new analysis suggests that wild, stray, and feral cats living in areas with higher human population density tend to shed a greater amount of the parasite that causes the disease toxoplasmosis.

NewsDrug-resistant fungi thriving in the most remote regions of Earth
New research has found that a disease-causing fungus — collected from one of the most remote regions in the world — is resistant to a common antifungal medicine used to treat infections.

NewsHospital infection shows dual colonisation strategy
Researchers have uncovered why one of the most dangerous nosocomial pathogens, Pseudomonas aeruginosa, is so difficult to combat - it follows a dual strategy, with some bacteria colonizing the tissue surface while others spread in the body.

NewsMicrogel treatment helps ‘good’ gut bacteria and clears out the ‘bad’
Researchers have developed a microgel delivery system for probiotics that keeps ‘good’ bacteria safe while actively clearing out ‘bad’ ones.

NewsResearchers develop adhesive bandage that can detect COVID-19 antibodies
Researchers at NYU Abu Dhabi have developed a new rapid testing method for COVID-19 – an adhesive bandage that relies on gold nanoparticles to quickly detect the immune antibodies in the bloodstream. These antibodies, named IgM and IgG, are naturally produced as a result of SARS-CoV-2 infection, ...

NewsCombining virus therapy with radiation to fight brain cancer works better than either treatment alone
Combining a cancer-targeting virus with radiation to treat brain cancer in mice was more effective than either therapy on its own, according to new research, providing hope for new treatments that combine immunotherapy with traditional surgery, chemotherapy or radiation.

NewsNewer Covid strains are less capable of surviving in the air
Scientists investigating why airborne viruses lose their infectivity have revealed how cleaner air kills the virus significantly quicker and why opening a window may be more important than originally thought.
