The meningococcal B (MenB) vaccine could provide protection against more than one disease, with new research linking it to a significant reduction in the risk of gonorrhoea in young people in parts of Australia.

Salidroside, the key active compound of Rhodiola plants with anti-hypoxia and anti-fatigue properties, is highly valued in medicine, health products, and cosmetics. A new study demonstrates an efficient dual-enzyme cascade system combining sucrose synthase and glycosyltransferase that achieves one-pot biosynthesis of salidroside with 90% conversion rate. Through solubility enhancement and thermostability engineering, the system produces 13.61 g/L salidroside within just 10 hours, establishing a practical platform for industrial-scale green production.

A novel study shows that exposure to air pollution, especially fine particulate matter like dust, soot, and smoke (PM_2.5), is associated with increased disease activity and flare risk in rheumatoid arthritis (RA). The findings from an article in the Annals of the Rheumatic Diseases (ARD), The EULAR Journal, published by Elsevier, underscore the importance for healthcare providers and policymakers to recognize its impact on the management of RA.
