A new study by 91ֱ�� researchers shows that chronic pain, often invisible to medical tests, can be better assessed when doctors take a holistic approach.

By combining biological data with information about patients’ mental health, sleep and stress, the researchers say they were able to create a fuller picture of chronic pain. They said their findings, published in Nature Human Behaviour, stand to improve how the condition is diagnosed and treated.

Study reveals trained immunity may cause lung damage

Trained immunity – a process being explored in vaccine and therapy development to boost immune defences – appears be counterproductive in certain contexts, researchers at 91ֱ�� and the Research Institute of the 91ֱ�� Health Centre (The Institute) have found.

Trained immunity is when the body’s first line of defence remembers past threats and becomes more reactive, responding more strongly to future infections even if they are different, by changing how immune cells behave.
