A Business Insider investigation into the US boom in AI data centers, mapping where they are, who owns them, and how much power and water they consume. It looks at the costs borne by communities, with a focus on Virginia.

Fermilab's Don Lincoln explains why light travels slower in water and glass. He knocks down common wrong explanations such as absorption and re-emission, then gives the wave-mechanics reason tied to refractive index.

Thunderf00t presents high-speed camera footage of alkali metals such as sodium and NaK reacting with water. The footage shows that the explosion is not caused by hydrogen ignition, as the usual explanation says. It is a Coulomb explosion driven by electrons leaving the metal.

Practical Engineering explains how canal locks work, including the water-saving basins of the new Panama Canal locks.

An Odd Lots podcast episode with Arizona hay farmer Trevor Bales on why growing alfalfa in the desert makes sense despite drought. He covers his family's history and the sun, pest and water arguments for farming there.

A one-minute demo comparing RetroArch shaders on the Sonic the Hedgehog waterfall, where Sega Genesis dithering creates a transparency effect. It shows how different shaders emulate the CRT look.

Linus Tech Tips argues that big air coolers beat AIO liquid coolers for most PCs. They compare quietness and temperatures, using the Noctua NH-U12A as the example.

Sciencium examines the Mpemba effect, the claim that hot water freezes faster than cold water. It walks through experiments and a published paper questioning the effect.
