Using a recently developed fluorescent imaging technique, researchers in the United States have developed high-resolution maps of microbial communities on the human tongue. The images reveal that microbial biofilms on the surface of the tongue have a complex, highly structured spatial organization. Source: How bacteria form communities on the human tongue

A cheap, biocompatible white powder that luminesces when heated could be used for non-invasively monitoring the temperature of specific organs within the body. Scientists have now conducted preliminary tests to demonstrate the applicability of this concept. Source: Sensing internal organ temperature with shining lights

Scientists have developed a solid material capable of slowly releasing hydrogen sulfide and nitric oxide when exposed to air. These gases can induce physiologically favorable effects at low concentrations (e.g., reducing inflammation and expanding blood vessels). However, their medical use has been limited due to difficulties in storing them and regulating their concentration. This material […]

In the production of compounds, chemists have the goal of finding strategies that are most selective and avoid waste products. This helps to drive industrial innovation and drug development. In this context, a team of researchers has developed a new approach to so-called allyl functionalization. Source: Teaching old transition metals new tricks: Chemists activate palladium […]

The first study looking at the effect of chlorhexidine mouthwash on the entire oral microbiome has found its use significantly increases the abundance of lactate-producing bacteria that lower saliva pH, and may increase the risk of tooth damage. “In the face of the recent COVID-19 outbreak many dentists are now using chlorhexidine as a pre-rinse […]

A new modelling study conducted in a simulated Singapore setting has estimated that a combined approach of physical distancing interventions, comprising quarantine (for infected individuals and their families), school closure, and workplace distancing, is most effective at reducing the number of SARS-CoV-2 cases compared with other intervention scenarios included in the study.

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and ‘second generation’ approaches are needed. Now, a team of engineers may have a way to predict which mutations will occur in people, creating an easier […]
