Graph Sandwich Conjecture Resolved Mathematicians have completed a decades-old proof showing that large random regular graphs can be rigorously “sandwiched” between two simpler random binomial graphs. The result, detailed on 18 September, lets researchers transfer many known properties of easy-to-analyze binomial graphs directly onto the harder regular graphs that better model real networks. It stands … Read more
Youngest Known Exoplanet Confirmed in Formation Astronomers have confirmed Elias 2-24 b as the youngest known planet, less than one million years old and roughly Jupiter-mass, still accreting material inside a gap in its host star’s protoplanetary disk about 450 light-years away. The finding, published in The Astrophysical Journal Letters and highlighted on 17 September … Read more
Solar Desalination Yields Fresh Water and Solid Minerals Researchers at the University of Rochester have demonstrated a solar-powered desalination system that converts seawater to fresh water while depositing nearly all dissolved salts as solids rather than liquid brine. Laser-etched black metal panels create superwicking surfaces that draw thin water films, evaporate them under sunlight, and … Read more
Webb’s Little Red Dots May Be Black Hole Stars Astronomers analyzing James Webb Space Telescope data continue to debate the nature of numerous compact, extremely red objects known as little red dots, abundant in early-universe images. A September 14 Quanta analysis highlights a bold interpretation: some are “black hole stars”—massive hydrogen envelopes powered by a … Read more
Black Hole Stars May Explain JWST’s Little Red Dots Astronomers analyzing James Webb Space Telescope data have proposed that many of the mysterious “little red dots” seen in the early universe are a new class of object: black hole stars. These would consist of a central black hole powering a vast hydrogen envelope the size … Read more
Quantum Microscope Integrates Trapped-Ion Computer Researchers in Austria are constructing an electron microscope linked to a trapped-ion quantum computer to extract more information from each electron. The system entangles free electrons with ions along the beam path, allowing quantum operations to combine weak signals into stronger ones. This could produce clearer images of fragile samples, … Read more
Quantum Operations Accelerated Over 1,000 Times Researchers at Chalmers University of Technology have developed a method using quantum lattice gates and single-period Floquet control that performs advanced operations on bosonic quantum codes more than 1,000 times faster. Previously requiring thousands of repeated driving cycles, these operations now complete in one cycle. This reduces the window … Read more
New Proof Advances Four-Color Theorem and Graph Coloring Mathematicians have produced a new computer-assisted proof of the four-color theorem, published online in March 2026 and highlighted on September 10. The result, by a team including Mikkel Thorup, Carsten Thomassen, Ken-ichi Kawarabayashi and others, reconfirms that any planar map can be colored with four colors so … Read more
AI Agents Prove Navier-Stokes Singularity OpenAI mathematicians announced on September 8 that a swarm of roughly 10,000 autonomous AI agents, running on an internal advanced model, produced a Lean-verified proof of a singularity (“blow-up”) in the three-dimensional Navier-Stokes equations. The result addresses one of the six remaining Clay Millennium Prize Problems and shows that smooth … Read more
AI Agents Crack Navier-Stokes Singularity OpenAI researchers announced on 8 September that a swarm of roughly 10,000 autonomous AI agents, running on an internal advanced model, produced a Lean-verified proof that the three-dimensional Navier-Stokes equations can develop a singularity, or “blow-up.” The result addresses one of the six remaining Clay Millennium Prize Problems and was … Read more
