Considerable gap in evidence around whether portable air filters reduce the incidence of COVID-19

There is an important absence of evidence regarding the effectiveness of a potentially cost-efficient intervention to prevent indoor transmission of respiratory infections, including COVID-19, warns a study by researchers at the University of Bristol.

Multi-drug resistant infection about to evolve within cystic fibrosis patients

Scientists have been able to track how a multi-drug resistant organism is able to evolve and spread widely among cystic fibrosis patients—showing that it can evolve rapidly within an individual during chronic infection. The researchers say their findings highlight the need to treat patients with Mycobacterium abscessus infection immediately, counter to current medical practice.

New, rapid CRISPR/Cas9 method identifies key genes in zebrafish spinal cord regeneration

A new, rapid screening approach uses CRISPR/Cas9 technology to identify immune system-related genes that play a crucial role in repairing zebrafish spinal cord injuries. Marcus Keatinge and Themistoklis Tsarouchas of the University of Edinburgh, U.K., and colleagues present these findings in the open-access journal PLOS Genetics.
