Among older adults in Spain, hospitalisation rates from respiratory syncytial virus (RSV) infection increases progressively with age and is more likely among people with other health issues and who live in nursing homes, according to a study published in Eurosurveillance. The hospitalisation rate varied considerably with age and the presence of risk conditions, with important implications for possible targeted interventions.

Researchers at Duke University and North Carolina State University have discovered a handful of new CRISPR-Cas systems that could add to the capabilities of the already transformational gene editing and DNA manipulation toolbox. Of the new recruits, one system from bacteria commonly found in dairy cows shows particular promise for human health.
