LabCoatz uses mass spectrometry, with help from other science YouTubers, to reverse engineer the Coca-Cola flavor and builds a chemically-identical replica. The video walks through a year of work on the formula.

A 105-minute technical deep dive from Noise In Space evaluating whether Starlink satellites could work as synthetic aperture radar. It covers SAR signal-to-noise, amplifiers, antennas, duplexing, phased array beamforming and simulations of V2 Mini and V3 satellites.

Veritasium explains how ASML's EUV lithography machines make the most advanced computer chips, covering the engineering of the light source, mirrors and the supply chain around them. It is a long-form explainer on the world's most complex commercial machine.

Veritasium explains how jet engines run hotter than their components' melting points, using cooling air and single-crystal superalloy turbine blades. It covers how the blades are grown as aligned crystals.

Linus Tech Tips builds a Linux PC together with Linus Torvalds, who talks through parts selection, kernel development and some of his side projects. The conversation also touches on AI in kernel work.

Mario Zechner explains why he built pi, a minimal coding agent, out of frustration with existing agent harnesses. He also discusses how AI agents are straining open source projects and argues for slowing down.

Scott Jenson, a veteran UX designer formerly at Apple and Google, argues that the 'UX/UI' split pits programmers against designers and narrows ambition in open source. He makes the case that desktop UX has stagnated and that open source projects could lead experimentation beyond current interaction models.

Scott Manley examines why SpaceX, Google and others are looking at orbital data centers. He walks through the economics, heat rejection and solar power arguments, with links to the Lumen/Starcloud and Google Suncatcher papers.

CGTN coverage of the 2026 Spring Festival Gala, in which humanoid robots perform synchronized martial arts routines alongside children.

Gamers Nexus benchmarks GPU gaming performance on Linux using the Bazzite OS, an exploratory first step toward establishing a Linux testing methodology. It compares results against Windows and notes where Linux still falls short.
