NASA's Astronomy Picture of the Day for October 19, 2026 shows a 2-million-light-year radio structure shaped like a treble clef, likely a black hole's old outburst revived by a collision of two galaxy clusters.
A liver condition affecting nearly 30% of adults worldwide may actually be five distinct diseases, including genetic forms linked to faster progression, according to a new Mayo Clinic study.
The 2026 Nikon Small World in Motion competition drew 347 entries from 40 countries. After a late disqualification, a roundworm and a single-celled predator now hold first place. Meet the top three.
Penn State researchers strapped small weights to the legs of growing guinea fowl. As adults, those birds carried extra load without paying any extra energy cost, while their unloaded peers burned 23% more. What might this mean for human kids?
In mice, olive oil given before glucose blunted the early blood sugar rise by slowing the stomach and recruiting glucagon, GLP-1 and the vagus nerve. Here is what that does and does not tell us.
A single-cell analysis of nearly half a million cells from 62 pancreatic tumors shows how cancer cells keep reshaping their genetic activity over time, helping some clones resist therapy and others spread.
A Science study of 1,543 human milk samples from Canada, Pakistan and Burkina Faso finds shared molecular patterns that tie maternal nutrition, mammary gland function and infant growth together, and points to seven candidate biomarkers.
A team from Wits University and the University of East Anglia shows that a carefully prepared beam of light, starting with no spin at all, can develop separated left- and right-handed regions just by travelling through empty space.
An experimental injection called CBL-514 triggers fat cells to die off on their own. Early human data show less visceral belly fat, but the results come from a small conference abstract, not a peer-reviewed paper.
