A NASA-funded air pollution monitoring network has provided one of the most detailed long-term views yet of the role of black carbon, or soot produced by fires, diesel vehicles, and other combustion sources, in Ethiopia’s capital, Addis Ababa. The detailed measurements show how pollution changes by time of day and season, including increases associated with

Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) conducted more than 140 hours of observations of the magnetar 1E 1547-5408, shown in this Aug. 5, 2026, artist’s concept, between March and April 2025. In doing so, they may have captured empty space behaving in a way physicists have predicted for 90 years, but never directly
Credit: bpawesome/Getty Replication of experimental results is important for building credible science, but replication studies are often difficult to find. A team of researchers wants to change that. They have begun publishing replication studies on the peer review platform PubPeer, along with links to the original studies. There have been numerous attempts to replicate scientific
Posting studies to preprint servers like bioRxiv is common practice in many scientific fields.Credit: Michael Szebor/Nature The central conclusions of biomedical preprints rarely change after peer review in a journal.1according to a study published on the preprint server bioRxiv this month. The research also found that studies that first appeared as preprints are retracted at
NASA’s James Webb Space Telescope gives us new insights into the distant future of solar systems like ours, as the agency continues to reveal the secrets of the universe and our place in it. Billions of years ago, a Sun-like star nearing the end of its life grew enormously in size to become a red
