The treadmill entered British prisons around 1818 as hard labor, but the modern fitness machine was not merely rebranded punishment: it descended through a separate line of laboratory and medical engineering
The treadmill has a prison in its family tree, but the familiar version in a gym was not simply rolled out of a Victorian cell and given a fitness logo. Around 1817, British engineer William Cubitt adapted an old human-powered…
Future cars may double as grid batteries, but only 22 current models can send power back: a global study found EV batteries could meet short-term storage needs by 2030 if participation and infrastructure arrive
The future car may do useful work while it is parked. An electric vehicle already carries a battery large enough to run a home for hours or days, depending on the home, the vehicle and the amount of charge reserved…
The Dalles spent 13 months fighting to keep Google’s water use secret — then records showed the data center campus consumed roughly a third of the Oregon city’s supply
The most revealing fact about Google’s water use in The Dalles is not just the size of the number. It is how difficult that number was for the public to obtain. The Oregon city did not spend two years fighting…
Google’s Willow quantum chip completed a benchmark in under five minutes that Google estimates would take a leading supercomputer 10 septillion years — roughly 725 trillion times the age of the universe
Five minutes versus 10 septillion years is the kind of comparison that makes every ordinary unit of time seem useless. Ten septillion is 10 followed by 25 zeros. Divide that by the universe’s age of about 13.8 billion years and…
Roman marine concrete can become stronger through interactions with seawater, helping explain why ancient harbour structures survived conditions that steadily destroy modern materials
For most concrete, seawater is an enemy. Salt penetrates pores, chemical reactions disrupt the cement paste and chlorides can reach steel reinforcement, where corrosion expands and cracks the surrounding material. Yet cores drilled from ancient Roman breakwaters tell a very…
One faint signal beamed down from space quietly runs your flights, your money, the power grid and the phone in your pocket, and right now someone is jamming and faking it over Europe on purpose
The signal in question is called the Global Navigation Satellite System, or GNSS. Most people know it by the name of the specific American constellation that first made it publicly available, GPS. In practice, four separate satellite constellations are currently…
The dairy industry spent a decade betting on fermentation tanks to replace cows — and a handful of plant biologists just found a cheaper shortcut hiding inside ordinary crop leaves
Cow’s milk without the cow has been a biotech goal for a decade, and the usual route runs through vats of genetically engineered yeast or fungi churning out casein and whey in industrial fermenters. A new line of research flips…
By the time 50 million had installed Meta’s smart-glasses app, few knew what sat unused inside it: dormant facial-recognition code that could spot a face, build a biometric signature, and flash ‘person recognised’ the instant it saw someone
Here is the line Meta would probably like you to walk away with: the code never ran, it was dormant, and users could not have triggered it. Within a day of the reporting that exposed it, most of it was…
Internal Facebook documents showed that the platform once weighted every reaction emoji five times more heavily than Likes — a design choice that quietly amplified provocative content because strong reactions like outrage counted for more
Beginning in 2017, Facebook’s ranking algorithm treated a reaction emoji as five times more valuable than a Like. Not the angry face specifically. All of them. Love, haha, wow, sad and angry each counted for five, while the old thumbs-up…
A 1948 IBM computer with no memory at all, fed by punchcards and programmed by physically rewiring its panels, was still doing the accounting at a Texas filtration company as recently as 2020
At Sparkler Filters in Conroe, Texas, accounting once meant carrying a deck of punched cards to an IBM 402, fitting the correct wired control panel into its side and listening as relays and mechanical counters turned the cards into a…
