NewsComFB protein discovery could help fight antibiotic resistance
Scientists have discovered a new family of bacterial proteins – called ComFB – that regulate both movement and DNA uptake – suggesting potential new methods to combat pathogenic infections.
-
NewsNew nanostructure makes CRISPR edits safer and three times faster
Northwestern University researchers have created DNA-coated nanoparticles that deliver CRISPR into cells three times more effectively while reducing toxicity. The advance could overcome one of the biggest barriers to gene-editing therapies.

ArticleGene therapies that listen and respond: the power of RNA regulation
Most gene therapies rely on static DNA promoters to control gene activity, but nature uses far more sophisticated tools. Dr Matthew Dale explores how harnessing RNA-level control could enable treatments that sense and respond in real time, offering unprecedented precision and safety.
