Drop a small ring of superconducting metal into a bath of liquid helium, nudge a current through it, and remove the power supply. The current does not fade. It circulates around the loop for years, indistinguishable at the end from the day it began. There is no battery, no source, no work being done against friction — because inside the metal, there is no friction to work against. This is not a metaphor or a rounding error. Experimental upper limits on the decay of persistent currents in superconducting rings suggest the current would still be measurable long after everyone who…
In a Milwaukee workshop in 1868, a former newspaper editor named Christopher Latham Sholes filed a patent for a machine he called the “Type-Writer.” The keys were arranged alphabetically across two rows, which seemed the obvious choice: letters in the order everyone already knew. It did not work. When a typist struck two neighbouring keys in quick succession, the slender metal typebars — the arms that swung up to strike the paper through an inked ribbon — collided and jammed against each other before they could fall back into place. The machine could type, but only slowly, and only if…

Key PointsH.R. 8781 amends the Education Amendments of 1972 to add statutory definitions of “sex,” “male,” and “female” based on reproductive biology.The definitions would apply to every education program receiving federal financial assistance, and nearly all public K-12 schools and virtually every college and university accepts federal student aid.The bill codifies the Supreme Court’s June ruling in West Virginia v. B.P.J. and Little v. Hecox, which held that Title IX allows athletic teams to be separated by sex and let stand state laws barring transgender athletes from girls’ and women’s teams. The House Education and Workforce Committee voted this week…
A modern reaction GIF still begins with six characters written for a dial-up service in the 1980s: GIF87a or GIF89a. Behind that header sits LZW compression, a palette containing no more than 256 colours, and a block structure that current browsers can read much as CompuServe originally described it. The first public Graphics Interchange Format specification is dated June 15, 1987. It defines GIF as a mechanism for storing and transmitting raster graphics, not as a tool for reaction clips, memes, or looping fragments of television. Steve Wilhite developed the format while working as a software engineer at CompuServe. The…
The outage began just after 9:37 a.m. Pacific time, in a data centre region called US-EAST-1, in Northern Virginia. Within minutes, Slack workspaces stopped loading images, Trello boards went blank, Medium articles refused to render, smart lightbulbs from companies like LIFX became unreachable, and even Amazon’s own service health dashboard — the page customers were meant to check for updates — could not update, because it depended on the same system that had just broken. Downdetector logged spikes across hundreds of services simultaneously. For roughly four hours, a meaningful slice of what people call “the internet” was, in practical terms,…
Key PointsA new analysis of more than 400,000 voters from the Cooperative Election Study (2016–2025) identifies a distinct and growing cluster of Americans: people with graduate degrees and household incomes of just $30,000 to $60,000 a year.Federal Reserve Bank of New York data shows 41.5% of recent college graduates are underemployed (working jobs that don’t require a degree) while their unemployment rate sits at 5.7% as of the first quarter of 2026.The squeeze is compounding: these households are often paying down student loans, saving for their kids’ college, and supporting aging parents at the same time, all while wondering what…
Americans now marry at around age 29 to 30 on average, right in the window when student loan balances are still large. With more than 42 million Americans holding federal student loans and total student debt topping $1.8 trillion, the odds are high that at least one person walks into a marriage carrying it. In many marriages, both spouses do.That makes student loans a marriage issue whether you like it or not. The good news: being married doesn’t make you legally responsible for a loan you never signed for. The complicated part: how you file your taxes and which repayment…

Key PointsMore than 80 House Democrats sent a letter to Education Secretary Linda McMahon demanding the Department abandon plans to move the Office for Civil Rights (OCR) to the Justice Department and the Office of Special Education and Rehabilitative Services (OSERS) to Health and Human Services.The lawmakers argue the transfers, executed through interagency agreements (IAAs), are unlawful because Congress created both offices in the Department of Education Organization Act and only Congress can eliminate or relocate them.OCR handles roughly 20,000 complaints per year, and OSERS oversees special education services for more than 6.7 million students under IDEA. House Democrats are…
