Moderate coffee intake linked to slower biological aging in people with severe mental illness

Drinking a maximum of 3-4 cups of coffee a day may slow the 'biological' ageing of people with severe mental illness, by lengthening their telomeres-indicators of cellular ageing-and giving them the equivalent of 5 extra biological years, compared with non-coffee drinkers, finds research published in the open access journal BMJ Mental Health.

Daily walking patterns help flag early Parkinson’s signs in large UK study

Accelerometer data from nearly 95,000 adults show that higher daily step counts predict lower short-term Parkinson’s disease risk. But as follow-up extends, the association fades, indicating that reduced steps are more likely an early marker than a cause.

Genetic signals reveal why erectile dysfunction develops and who is most at risk

This multi-ancestry genomic study identifies key genetic loci underlying erectile dysfunction and shows that ED risk is shaped by both cardiometabolic and substance use–related genetic pathways. Using EHR-linked data, the researchers uncover SIM1-related mechanisms, modest PRS performance, and bidirectional genetic links with obesity, diabetes, and addiction traits.
