Sir Clive Sinclair launched the C5 at Alexandra Palace on 10 January 1985, promising a £399 electric machine that could move through British streets at 15 miles per hour while its driver sat lower than the bonnet line of many cars. It was not licensed like a car. It was not protected like one either. The driver sat close to the road, legs stretched forward, hands on a steering bar beneath the knees. In mixed traffic, the white plastic shell put a human head near the wheel arches and exhaust lines of vehicles built on a completely different scale. The…
Blue Origin’s New Glenn rocket explodes in testing
Here’s the thing that’s been bugging a lot of physicians about the whole AI-in-medicine conversation. Everyone keeps asking the same question: Will AI replace doctors? It’s the scary headline. Understandable. But there’s a bigger, more uncomfortable question sitting right underneath it that almost nobody is talking about. Who owns the AI layer, and will physicians have any say in it? Disclaimer: While these are general suggestions, it’s important to conduct thorough research and due diligence when selecting AI tools. We do not endorse or promote any specific AI tools mentioned here. This article is for educational and informational purposes only.…
The S&P 500 is flashing a green light to investors.
On July 9, 1962, a Thor rocket carrying a W49 thermonuclear warhead detonated roughly 250 miles above Johnston Atoll in the central Pacific. The yield was 1.4 megatons. The test was called Starfish Prime, and within seconds its electromagnetic pulse reached Hawaii, blowing fuses in streetlights, setting off burglar alarms, and damaging a telephone company microwave link nearly 900 miles from the burst. The distance was the shock. Hawaii was not near the test site in any ordinary sense. Honolulu sat beyond the horizon from Johnston Atoll, far enough away that the visible blast belonged to the sky, not the…
When headlines declared that an MIT study had proven ChatGPT “makes you stupid,” the researchers behind it published an FAQ asking journalists to stop using words like “dumb” and “brain rot,” because their paper, based on 54 students writing essays, never said anything of the kind. The study came out of the MIT Media Lab in June 2025, and it examined what happens in the brain when people write essays with the help of ChatGPT. Within days it had been compressed, across headlines and social media, into that single claim, and the study became shorthand for a fear a lot…
Brazil’s government, federal district agree on BRB loan deal
More than 600 University of California faculty members, led by mathematicians at UC Berkeley, are calling on the system to reinstate SAT or ACT testing for STEM applicants beginning with the fall 2027 admissions cycle, warning that six years of test-free admissions have left professors teaching middle-school math to incoming college freshmen.The open letter, addressed to UC Regents, the UC Office of the President, and Academic Senate leadership, lands days before the UC Academic Senate’s Board of Admissions and Relations with Schools is scheduled to discuss system-wide admissions changes, which is potentially the first step toward restoring standardized testing at…
Two identical records left Earth in 1977, one bolted to each Voyager spacecraft. The disc is the part most people picture: gold-plated copper, about thirty centimetres across, assembled by a committee led by Carl Sagan and carrying greetings, music and the sounds of a planet. The cover is the part worth slowing down on. Among the diagrams etched into it sits a small spot of metal, around two centimetres across, that does something none of the rest of the record does. It keeps time. What sits on the cover The cover is aluminium, and electroplated onto it is an ultra-pure…
Stocks in the nation’s Strategic Petroleum Reserve are near their lowest in more than 40 years — but it may not matter
