NewsAlarming antibiotic resistance discovered in war-torn Ukraine
Microbiologists investigating bacterial resistance among the war-wounded Ukrainian patients treated in hospitals have warned that the entire European region is under threat after finding that many were affected by bacteria that exhibited an extremely high level of antibiotic resistance.

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.

NewsNearly half of TB cases in prisons worldwide go undetected
In the first global assessment of tuberculosis among incarcerated people, a new study found consistently high TB case rates and low case detection in prisons.

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.

NewsCRISPR-like system in eukaryotes can edit the human genome
The first RNA-guided DNA-cutting enzyme found in eukaryotes, Fanzor could one day be harnessed to edit DNA more precisely than CRISPR/Cas systems.
