Physicist John Wheeler proposed to Richard Feynman in a 1940 phone call that every electron and positron in existence could be a single particle tracing a tangled path back and forth through time. Sections of this path moving forward in time appear as electrons, while sections looping backward appear as positrons. Physicist E. C. G. Stueckelberg independently arrived at a similar concept around the same period.
According to a JPMorgan note cited by Semi Doped, ASML has no plans to adopt free-electron laser (FEL) technology for extreme ultraviolet lithography, despite backing from Elon Musk for that approach. Instead, ASML is continuing to refine its existing laser-produced plasma (LPP) method, aiming to boost source power from around 500W to 1,000W and nearly double the rate of tin droplet generation to 100,000 per second.
Amazon has released Pizza Bot, an open-source tool under Apache 2.0 that organizes long-running AI agent tasks into an inbox-style interface. Completed tasks land in an 'Unread' queue while tasks needing human approval land in an 'Action' queue, letting users start work and check back later rather than watching agents run in real time.
Paleontologists studying microscopic pores on fossilized Fusioolithus eggshells, linked to massive titanosaurs, concluded these giant dinosaurs could not incubate eggs by sitting on them due to their enormous size. Instead, the study led by Kohei Tanaka and Darla Zelenitsky suggests titanosaurs buried their volleyball-sized eggs in piles of decaying vegetation, similar to how modern crocodiles incubate their nests, even in surprisingly cool, far-from-equator climates.
Chinese high-purity quartz maker Jiangsu Pacific Quartz, which already supplies furnace tubes and wafer boats to Lam Research and Tokyo Electron, has had its quartz components certified by a Chinese DRAM producer believed to be CXMT for 300mm wafer production. The materials meet the 4N5–5N purity level needed for semiconductor process equipment, giving China a more domestic supply chain for chipmaking consumables.
Researchers examined a fragment of 'hiroshimaite,' fallout material from the 1945 Hiroshima atomic bombing, and identified a previously unknown alloy composed of seven elements. The discovery, imaged via scanning electron microscope, was published in Science Advances ahead of the bombing's 81st anniversary.
A community developer has released an unofficial build that repackages Cursor's Electron-based Grok Bot app, officially available only for macOS and Windows, so it runs natively on Ubuntu and other Linux distributions. The project swaps out Windows-only native components and packages the app as a .deb, tarball, or AppImage, currently targeting Grok Bot version 0.29.0 on Electron 42.1.0.
Physicists at the Beijing Electron Positron Collider II presented new analysis showing the particle X(2370) is likely a glueball, an exotic particle theorized nearly 50 years ago to be made entirely of gluons rather than quarks. The findings, detailed in a preprint shown at a physics conference in Brazil, build on 2024 work that measured the particle's mass and spin, now adding data on its decay modes and flavor-singlet structure.
