news Chemistry Evidence status: Peer reviewed · Laboratory measurement on a metal surface
A carbon nanoribbon built only from five- and seven-membered rings conducts like a metal, a Nature study reports, though only in short pieces grown on silver.
news Astronomy Evidence status: Official announcement · Preprint
Rubin Observatory's first dwarf-planet candidate, 2026 ED138, orbits beyond Pluto about 47 au out. Its 612 to 1,530 km size rests on an unmeasured albedo.
news Astronomy Evidence status: Peer reviewed · Laboratory analysis of one meteorite
Teghaza 001, an 800 g Sahara meteorite, formed at least 4.1 billion years ago and samples Mars's early crust and a primordial mantle source, Science reports.
news Biology Evidence status: Peer reviewed · Computational model of four connectomes
Simulations of four fly connectomes converge on a three-neuron loop as the walking rhythm generator. Two predictions held in flies; its cells are untested.
news Astronomy Evidence status: Peer reviewed · Observations of one system
JWST and ALMA find two feeding black holes 4,900 light-years apart in a merger 1.3 billion years after the Big Bang. How we know, and the X-ray caveat.
news Earth Evidence status: Peer reviewed · Hindcast evaluation plus one real-time competition year
Nature study: probabilistic bias correction doubles ECMWF's AI model's week 3 to 4 forecast skill, from 0.03 to about 0.06. What that does and does not mean.
news Earth Evidence status: Official announcement
Metrology delegates voted on 15 October 2026 to end leap seconds: from 20 May 2027 UTC runs continuously and may drift up to 3,600 s from Earth time.
news Paleontology Evidence status: Peer reviewed · Single specimen
A braincase bought by the Natural History Museum in 1924 is Europe's first megaraptoran: Invictibellatrix amberina, a 3–4 m predator from the Isle of Wight.
news Astronomy Evidence status: Peer reviewed · Population study of catalogue data
A Nature Astronomy study of 298 multi-planet systems finds two families split by planet mass and tied to host star mass and metals, with a bias caveat.
