Battery Health isn't a bug or bad luck, it's chemistry. Here's what actually degrades a lithium-ion cell, and which habits genuinely speed it up.

Static shocks from car doors spike in dry, cold weather for a specific physics reason involving friction, fabric and where the charge finally finds ground.

Three space-weather words get used interchangeably and describe three different things. The sequence, not the synonym, explains what actually reaches the ground.

Kp is a three-hour magnetism index that aurora chasers borrowed. It tells you whether tonight is worth staying up for, and almost nothing about whether you will actually see the northern lights.

The chime you did not ask for has a cause, and it is usually a hearing-safety feature that needs a listening mode switched on to work at all.

Two buttons on the same earbuds, doing exact opposite things. A plain guide to which mode fits the flight, the sidewalk, and the open-plan office.

Noise-cancelling headphones fight sound with sound. Here is how active noise cancellation uses microphones and anti-noise, and why it beats a plane engine but not a nearby voice.

AI data centers are on track to use as much power as Japan by 2030. Here is why the chips draw so much electricity, how much water cooling takes, and what it means for your bill.

A solar flare mostly scrambles radio and GPS. The real grid threat is the coronal mass ejection behind it. Here is how a geomagnetic storm damages transformers.

Google, Apple and your bank keep asking you to make one. A passkey is a login that never sends its secret across the wire, which is why it beats the password at the thing passwords fail at most: phishing.

The $30 million mission is the first attempt by a private spacecraft to capture a U.S. government satellite that was never built to be caught.

The hardest frauds to stop are the ones the victim authorises. Apple's new iOS 27 framework watches the behaviour, not just the password.

A University of Minnesota team says its lab-built "SpudCell" can feed, grow and divide using only non-living parts, a milestone that comes with an asterisk: peer review hasn't happened yet.

NOAA’s Space Weather Prediction Center has issued a G2 geomagnetic storm watch for July 3 after the sun’s biggest flare of the week triggered radio blackouts across North America.

From January 2028, new PlayStation titles will ship digital-only. Games out before then keep their discs, but the retail box is on its way to becoming a keepsake.

The world's largest digital camera has begun a decade-long film of the southern sky, imaging it every few nights to catch whatever moves or flares.

Google's cheapest image model yet costs $0.034 per 1,000 pictures and, on the company's own benchmark, edges out its pricier sibling.

Genetic data from 1.6 million tropical insects and a wasp survey in Costa Rica suggest most of the planet's insect life has never been recorded.

WhatsApp began letting its three billion users reserve a username on Monday, ahead of a feature that will allow messaging without sharing a phone number.

Knuckling shots aren't luck. NASA's wind tunnels and space-station experiments explain how the four-panel Trionda ball swerves through this World Cup.
