American science took a beating this year, with cuts to funding, jobs and credibility. And yet, scientists persisted and made progress. These advances in 2025 spotlight how crucial it is to support biomedical research — and how much of an impact it can have on people’s lives. Huntington’s disease is a progressive neurological disorder that steals people’s control over their bodies. Patients may freeze up or involuntarily jerk or writhe. Doctors have no effective treatments, but an experimental drug could change that. The drug consists of a virus carrying tiny bits of RNA that halt the production of disease-causing proteins. Injected into the brain, the treatment slowed Huntington’s progress by up to 75 percent — a triumph for scientists and a promising sign for patients.
