Scientists have used machine learning to find drugs already on the market that could also fight COVID-19 in elderly patients. “Making new drugs takes forever,” said study co-author Caroline Uhler, a computational biologist at MIT. “Really, the only expedient option is to repurpose existing drugs.” The study team searched for potential treatments by analyzing changes to gene expressions in lung cells caused by both the disease and aging. Uhler said this combination could help medical experts find drugs to test on older people: We need to look at aging together with SARS-CoV-2 — what are the genes at the intersection of… This story continues at The Next Web
