Astronomers have found evidence for a possible first-of-its-kind "superkilonova," or a kilonova spurred by a supernova. Such an event has been hypothesized but never seen.
More than a decade ago, Northwestern chemists and materials scientists reported in Nature the first solid-state solar cell based on a halide perovskite semiconductor — an advance that ultimately helped launch one of the fastest-growing revolutions in solar energy.
Researchers developed DeepMet, a new AI system that sharply improves long-range weather forecasting across the U.S. The model predicts key temperature and humidity patterns up to 45 days ahead with far greater accuracy than current systems, helping identify extreme heat and cold events earlier. DeepMet offers faster, more reliable guidance for climate preparedness and public-health protection.
A University of Maryland, Baltimore County (UMBC) study, published in Nature Communications, uncovers how enteroviruses—including those causing polio, myocarditis, encephalitis, and the common cold—hijack host cell machinery to replicate. Researchers determined the structure of a cloverleaf-shaped RNA element in the viral genome bound to the viral protein 3CD, which recruits host factors to form the viral replication complex. 3CD also acts as a switch between genome copying and protein synthesis. This highly conserved mechanism across all seven enteroviruses in the study presents a stable target for developing broad-spectrum antiviral drugs that could disrupt this essential interaction and prevent replication.
Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable, autonomous robots: microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each. Barely visible to the naked eye, the robots are smaller than grains of salt and could advance medicine, manufacturing and more.
