Researchers from the Broad Institute and Mass General Brigham have shown that a low-oxygen environment — similar to the thin air found at Mount Everest base camp — can protect the brain and restore movement in mice with Parkinson’s-like disease. The new research, in Nature Neuroscience, suggests that cellular dysfunction in Parkinson’s leads to the accumulation of excess oxygen molecules in the brain, which then fuel neurodegeneration — and that reducing oxygen intake could help prevent or even reverse Parkinson’s symptoms.

Users of the NHS Active 10 app, designed to encourage people to become more active, immediately increased their amount of brisk and non-brisk walking upon using the app, according to researchers from the University of Cambridge. In a study published today in Nature Digital Medicine, the researchers found that while activity levels then slowly declined over time, even after 30 months those users who were still using the app were more active than they had been beforehand.

Researchers analysed the profile of adults who claim to have past-life memories, the features of these memories, and their associations with mental health, happiness, and religiosity/spirituality. The results indicated a high prevalence of mental disorder symptoms, with religiosity and spirituality being protective factors.
