To further improve agricultural yields, it is helpful to identify factors […]

Scientists turned toxic pesticide into treatment against antibiotic-resistant bacteria

N-Aryl-C-nitroazoles are an important class of heterocyclic compounds. They are used as pesticides and fungicides. However, these substances could be toxic to humans and cause mutations. As they are not frequently used, there is little data about them in the medicinal chemistry literature. However, it has been suggested recently that the groups of compounds that […]

Light flips genetic switch in bacteria inside transparent worms

AI-designed serotonin sensor may help scientists study sleep and mental health

Serotonin is a neurochemical that plays a critical role in the way the brain controls our thoughts and feelings. For example, many antidepressants are designed to alter serotonin signals sent between neurons. In an article in Cell, National Institutes of Health-funded researchers described how they used advanced genetic engineering techniques to transform a bacterial protein […]

Surveillance of antimicrobial resistance could be more challenging outside of the EU

In a new report from the Microbiology Society, experts from around the UK explain the desperate need for long-term and ambitious funding for surveillance and research into antimicrobial resistance (AMR). The next pandemic is likely to be associated with antimicrobial resistance, they say, and improved surveillance systems to monitor the evolution of AMR over time […]

Blood pressure drug may be key to increasing lifespan, new study shows

This suggests that metolazone, despite being an anti-hypertension drug, can be used in… view more  Credit: Eriko Kage-Nakadai, Osaka City University Since time immemorial, people have been fascinated by ways to stop aging. Nearly every culture has stories […]

Potential cholera vaccine target discovered

BOSTON – Findings from a team led by investigators at Massachusetts General Hospital (MGH), reported in the online journal mBio, may help scientists develop a more effective vaccine for cholera, a bacterial disease that causes severe diarrhea and dehydration and is usually spread through contaminated water. The bacterium that causes cholera, called Vibrio cholerae, settles […]
