SpaceX targets first full Starship booster and ship reuse attempt this weekend

SpaceX plans to launch Starship on Friday from Starbase, Texas, followed by an upper stage landing attempt about 22.5 hours later on Saturday, aiming for full recovery of both vehicle stages. Separately, Rocket Lab is preparing Electron's 100th overall mission, launching from New Zealand's Mahia Peninsula on November 14 to carry another iQPS radar satellite, marked with a special gold-and-black livery.

New project Zebkit packages Chromium engine as an embeddable library

Zebkit offers Chromium's core components—Blink, V8, PDFium, FFmpeg and more—as a single library that developers can link directly into their own applications, rather than a full browser or Electron-style runtime. It provides one API across Linux, macOS and Windows, with bindings for C, Rust, Python and JavaScript, letting apps add web views, PDF rendering, media playback and other Chromium features while keeping their own process, toolkit and packaging.

Discord's experimental Rust client loads faster than Electron app in viral demo

Discord co-founder Stanislav Vishnevskiy posted a 15-second clip showing an in-development Rust-based client, internally called Discord Phoenix, finishing a cold start and loading the friends list before the current Electron app even displays its interface. Discord staff confirmed both apps launched from a true cold start, and noted the Rust client used about 290MB of RAM while running two accounts simultaneously.

OpenAI sets January 2027 retirement date for ChatGPT Classic app

OpenAI is phasing out the original ChatGPT Classic desktop app, displaying a notice that it will be retired on January 30, 2027, with chat history carried over to the newer unified app. Separately, OpenAI is preparing to merge the Chat and Work tabs into one interface, consolidating their usage allowances.

Physicists trap positrons, the electron's antimatter counterpart, for study

Researchers report successfully capturing and holding positrons, the antimatter equivalent of electrons, using a trapping technique described in a Nature briefing discussion. The achievement allows scientists to study the particles' properties in a controlled setting over an extended period.

Felix Rieseberg details engineering career spanning Anthropic, Notion, Stripe, Slack, Microsoft

Felix Rieseberg's personal homepage outlines his current role leading engineering for Claude.ai, Cowork, and Code Desktop at Anthropic. It also recaps prior leadership positions at Notion (2023-2025), Stripe (2021-2023), Slack (2016-2021), and Microsoft (2014-2016), alongside his long-running work as an Electron co-maintainer and author of open source projects like windows95 and clippy.

SK Hynix, Samsung, SoftBank shares drop sharply amid Asia chip sell-off

SK Hynix fell more than 8% and Samsung Electronics dropped 7.9%, both hitting their lowest intraday levels since August, as a US semiconductor sell-off spread to Asian markets. SoftBank Group shares sank over 8% in Japan, dragging down chip-related names including Tokyo Electron, Advantest, Lasertec, Disco and Renesas Electronics. The moves followed a 0.44% Nasdaq decline and a 3.9% drop in Micron Technology after China's ChangXin Memory Technologies reported progress on a new chip architecture.

Researchers detail method for precisely controlled growth of 2D MoS2 semiconductors

A research team describes a metal-organic chemical vapor deposition (MOCVD) process that grows monolayer MoS2 and MoS2-MoSe2 superlattices with spatially controlled nucleation, using an etching-flux barrier patterned via electron-beam lithography on sapphire or SiO2 substrates. The technique relies on tuning gas flow rates, temperature and pressure, with HfO2 or ZrO2 barriers defining where crystal growth begins.

Study maps water's hydrogen bonding inside carbon nanotubes via vibrational spectroscopy

Researchers examined vibrational spectra from eight water-filled carbon nanotubes alongside dozens of empty ones, finding distinct spectral signatures for 'non-H-bonded' and 'bulk-water-like' states of confined water. Most empty nanotubes showed no peaks in the relevant energy range, though a few displayed faint or contamination-related signals, and cryogenic measurements confirmed the key spectra on the same sample.

Discord to roll out experimental 'Game Mode' next week to cut resource use

Discord confirmed on X that an experimental Game Mode, spotted in leaked screenshots over the weekend, will begin rolling out to users next week. The toggle is designed to reduce Discord's CPU and GPU usage while a game is running, and the company says it plans to add more resource-saving features over time.

Wheeler's 1940 'One-Electron Universe' Idea Shaped Feynman's Physics

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.

ASML rejects free-electron laser approach for EUV, sticks with plasma light sources

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.
