Whether space-time exists should be neither controversial nor even conceptually challenging, given the definitions of "space-time," "events" and "instants." The idea that space-time exists is no more viable than the outdated belief that the celestial sphere exists: both are observer-centered models that are powerful and convenient for describing the world, but neither represents reality itself. /news/2025-09-space-doesnt-framework-reality.html General Â鶹ÒùÔºics Wed, 24 Sep 2025 15:40:02 EDT news677945634 Rice University researchers used a focused electron beam to pattern device functions with submicron precision directly into an ultrathin crystal. The approach produced traces narrower than the width of a DNA helix that glow with bright blue light and conduct electricity, showing it could be used to manufacture compact on-chip wiring and built-in light sources. /news/2025-09-scientists-electrons-pattern-sources-wiring.html Nanophysics Nanomaterials Wed, 24 Sep 2025 13:33:40 EDT news677939615 At a humming factory in the Spanish town of O Carballino, workers sling dozens of limp octopuses into a metal cauldron, wincing as strings of slime splatter their aprons. Nearby, others slice tentacles and pack them into vacuum-sealed bags destined for restaurants and retailers across Europe, Asia and the United States—part of a growing global appetite for an animal that's become increasingly scarce in its native waters. /news/2025-08-octopuses-dwindle-spanish-suppliers-imports.html Ecology Wed, 13 Aug 2025 03:30:19 EDT news674274603 Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, they produce ferroelectric materials with an intrinsic polarization (i.e., in which positive and negative charges are spontaneously separated), which can be switched using an external electric field that is perpendicular to them. /news/2025-08-domain-walls-polarization-ferroelectrics.html Nanophysics Nanomaterials Mon, 11 Aug 2025 13:10:01 EDT news674133369 As a mild-mannered statistics professor, it's not often that I get contacted directly by the CEO of a multi-million-dollar company, much less regarding allegations of cheating and malfeasance among world champions. /news/2025-07-im-statistics-professor-embroiled-world.html Mathematics Wed, 09 Jul 2025 13:28:28 EDT news671286502 Solving life's great mysteries often requires detective work, using observed outcomes to determine their cause.

What about new materials for extreme conditions, such as in jet engines and spacecraft? The answer, says Fadi Abdeljawad, an associate professor of materials science and engineering in Lehigh University's P.C. Rossin College of Engineering and Applied Science, might be hidden in the infinitesimally tiny regions, or boundaries, where atoms in crystals come together. /news/2024-10-corners-atoms-path-materials-extreme.html Nanomaterials Wed, 16 Oct 2024 14:43:21 EDT news648308592 Approaching downstate Decatur by car, it's not unusual to smell the huge Archer Daniels Midland industrial complex before seeing it. The sweet aroma of fermenting grain wafts through vehicle windows and air vents, a sign that ethanol fuel is being brewed.
