Research led by biomedical scientists at the University of California, Riverside, has identified a brain protein driving damage due to neuroHIV, pointing toward a possible treatment.

Loneliness and social isolation are linked to a range of serious health problems, but their overall toll on healthy life has been hard to quantify until now. In a first-of-its-kind study published in Nature Communications, Tulane University researchers analyzed data from 277,489 UK Biobank adults tracked for more than a decade. They found men experiencing both loneliness and social isolation lost up to six years free from depression and anxiety. Women, meanwhile, lost roughly four fewer years.
