BETHESDA, MD – The tiny fatty capsules that delivered COVID-19 mRNA vaccines into billions of arms may work better when they’re a little disorganized. That’s the surprising finding from researchers who developed a new way to examine these drug-delivery vehicles one particle at a time—revealing that cramming in more medicine doesn't always mean better results. The research will be presented at the 70th Biophysical Society Annual Meeting in San Francisco from February 21–25, 2026.
Public misunderstanding about medical aid in dying in the United States falls into two distinct categories – misinformation and uncertainty – and each is driven by different forces, according to Rutgers Health researchers.
Their study, published in the Journal of General Internal Medicine, found that misinformation about legality of medical aid in dying – a voluntary medical practice for terminally ill adults often abbreviated as MAID – is primarily shaped by ideology, while uncertainty is linked to structural barriers such as education level and financial strain.
