NewsNatural molecule added to toothpaste may help prevent plaque and cavities
Scientists have discovered that 3,3′-Diindolylmethane (DIM), a naturally occurring molecule also known as bisindole, reduces the biofilms that produce plaque and cavities by 90% and is also found to have anti-carcinogenic properties.

NewsNew CRISPR gene editing approach opens up more of the genome
Scietnists have come up with a new way to identify diverse CRISPR RNA variants that can specifically home in on challenging areas of DNA to target for editing. The new approach opens up more of the genome for editing, enabling the repair of mutations associated with more diseases.

NewsFuture medicines could feature ingredients targeting bacterial motility and chemotaxis
Future medicines will probably be made up of a cocktail of compounds that inhibit different bacterial targets, including some that act against their motility and chemotaxis mechanisms, a new review suggests.

News‘Hospital pathogen’ widespread in Vietnam’s environment
A pathogen considered to be a cause of hospital infection is widespread in Vietnam, turning up in farm soil and pig faeces as well as hospital beds and toilet floor surfaces, with 70% of isolates found to be resistant to at least one class of antimicrobials.

NewsCyanotriazole compounds can rapidly cure trypanosome infections in mice
Scientists have identified a class of cyanotriazoles (CTs), which exhibit potent trypanocidal activity and lead to rapid clearance of parasites both in vitro and in mouse models of Chagas disease and human African trypanosomiasis.
