πŸŽ“ Tutoring Centers Are Giving In to AI The Australian Dymocks is closing five Sydney tutoring centers after struggling to compete with AI. Company director Mark Buckland says the technology has made the business model unsustainable. "Most of our customers would be better off using their hard-earned cash on cheaper solutions rather than simply paying for overpriced tutoring," Buckland frankly admits. An AI subscription costs around $20–30 a month, while a human tutor can cost hundreds of dollars per subject each term. Dymocks still believes a real teacher provides a better learning experience than a chatbot, but for many families, that difference no longer justifies the cost. ✈️ Students themselves are also increasingly choosing AI tutors. In the U.S. alone, the share of high school and college students using AI to help with homework rose from 48% to 62% between May and December 2025. Dymocks appears to be one of the first to accept these irreversible changes in education. Will AI replace human tutors? ❀️ β€” Yes, it already is πŸ”₯ β€” No, students still need human teachers @hiaimediaen

    πŸ’‘ To Read the Herculaneum Scrolls, a Researcher Made New Papyrus Scrolls-and Burned Them Former banker and inventor Douglas Seiler came up with a way to read the charred scrolls of Herculaneum without physically unrolling them. To test his idea, he made his own scrolls and burned them. ℹ️ The ancient Roman city of Herculaneum was buried by the eruption of Mount Vesuvius in 79 CE, along with the only known intact library to survive from antiquity. Around 1,800 charred scrolls and fragments remain. Physically unrolling them can reduce the fragile scrolls to dust, while X-rays struggle to distinguish the text from the papyrus because both the carbon-based ink and the charred papyrus are largely made of carbon. But researchers have previously found lead in the ink of some ancient papyri, including fragments from Herculaneum. Lead is much easier to detect with X-rays. Seiler's idea could therefore provide a relatively quick and inexpensive way to identify the scrolls with the best chance of being read. βš™οΈ For the experiment, Seiler sourced papyrus and reed pens from Egypt and traditional lampblack ink from Japan. Chemists he knew helped prepare inks with different concentrations of lead. Seiler then paid high school students to write passages from "Star Wars," the Bible, and the 1960s sci-fi series "The Outer Limits" on the papyrus. The scroll was later carbonized in a high-temperature furnace in Seiler's home lab, inside a steel container with very little oxygen. Physicists at NIST scanned the charred scroll using X-ray CT. They then virtually unrolled it using software originally developed to analyze the "jelly rolls" inside lithium-ion batteries. The lead in the ink absorbed up to 25 times as many X-rays as the charred papyrus, making even tiny concentrations of lead stand out. "If you look at the images, the letters light up like a Christmas tree," Seiler said. πŸ“Œ The researchers now propose screening real Herculaneum scrolls with an inexpensive handheld X-ray fluorescence scanner. Scrolls showing traces of lead could then be prioritized for more detailed X-ray tomography. The synthetic scrolls can also provide ground-truth training datasets for developing and validating AI-driven text-detection algorithms. πŸ‘¨ Seiler conceived the project and helped fund it himself, becoming the paper's first author. His path into science was unusual: before retiring, he worked in real estate and banking and as an inventor. He became interested in the Herculaneum scrolls while working with Berkeley SETI on PANOSETI, a telescope project designed in part to search the sky for signs of extraterrestrial technology. @hiaimediaen
