New study discovers why 'persister' cells never say die

A recent study published in Journal of Bacteriology has identified the HipA gene responsible for making persister cells resistant to antibiotics. Biofilm infections, which can cause fatal lung infections, periodontal disease, and other serious health issues, are notoriously difficult to treat.

Wobble hypothesis stands up, NC state researcher finds

A study published in Nature Structural and Molecular Biology reveals that cellular modifications to tRNA enhance its ability to decode genetic information at the atomic level. The research supports Agris' Modified Wobble Hypothesis, suggesting that modified nucleosides enable tRNA to decode more than one DNA code.
