On April 8, 2024, volunteers participating in NASA’s Eclipse Megamovie citizen science project all around the United States hurried to photograph the solar eclipse with the latest, greatest equipment, capturing groundbreaking images of the Sun’s corona. Now, the Eclipse Megamovie team has released the remarkable new dataset that resulted from this effort — the first-ever, white-light eclipse dataset with calibration frames, spanning more than a cumulative hour and a half of observations of the solar corona. This data, which includes 52,469 total photographs uploaded by project volunteers, is now live: https://eclipsemegamovie.org/database. The data include contributions from 143 unique, mobile, volunteer-led…

Researchers from the American Institute of Physics’ publishing arm have developed a technique that could change how smartphones are inspected for tampering and hidden modifications. Instead of physically examining a device, the team demonstrated a way to detect whether a smartphone has been altered using radio-frequency signals from a distance. Andrey Matveev / Pexels The work introduces what researchers describe as a robust over-the-air testing platform that analyzes how a smartphone’s radio hardware behaves when it communicates wirelessly. The idea is surprisingly simple. Every phone’s radio components produce a unique “fingerprint” when transmitting signals. If a device has been modified,…

Twitch announced on Tuesday that it’s revamping its suspensions policy to shift away from its previous all-or-nothing penalty system. Until now, a temporary suspension on Twitch meant losing access to the platform altogether, including the ability to chat, watch streams while logged in, and access basic information. Now, the company is implementing two suspension types: streaming suspensions and chatting suspensions. The company notes that while its previous approach was easier to implement, its new targeted enforcement system means that the restrictions will match the specific offense committed. If a user violates Twitch’s Community Guidelines during a livestream, their account will…

Gemini, Google’s flagship artificial intelligence platform, is reportedly breaking the Google TV experience for some users. As reported by Tom’s Guide, several users of the smart TV platform have taken to Reddit with videos and photos of a novel search loop glitch in action, which appears to cause a perpetual cycle of displaying the onboarding process for Gemini-powered search. As per these Redditors, hitting the search button within Google TV prompts a splash screen to appear on-screen, which reads: “Meet Gemini for TV, your upgraded AI voice assistant.” Despite going through with the wizard, the splash screen reappears after each…

The inner workings of large AI systems remain largely opaque, raising significant safety and trust issues. Researchers have now developed a technique to extract and manipulate the internal concepts governing model behavior, providing a new way to understand and steer their activity.Modern AI models are marvels of engineering, but even their creators remain in the dark about how they represent knowledge internally. This is why subtle shifts in prompting can produce surprisingly different outputs. Simply asking a model to show its work before answering often improves accuracy, while certain deliberately malicious prompts can override built-in safety features.This has motivated significant…

Xiaomi has brought out a petite new battery with MagSafe charging – the Xiaomi UltraThin Magnetic Power Bank 5000 15W measures only 6mm thick and weighs 98g. As you can tell by the overly descriptive name, this is a 5,000mAh power bank that can output up to 15W wirelessly using Qi2. It also has a USB-C port on the bottom – that is normally used to charge the battery itself, but it can also be used to charge a phone faster as the wired connection goes up to 22.5W. The battery is tiny but mighty enough to charge two devices…

Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test. The Lenovo ThinkPad Lineups have regularly faired quite well in our reviews. In the real world, outside of testing studios, they also review very well. I’ve had my hands on the Lenovo ThinkPad P16 Gen 3 for the last few weeks. In that time, I’ve found myself grabbing it regularly, even among other laptops I am testing right now. I remember the P16 Gen 2 that I tested almost…

Source: Getty Images When Chinese AI company DeepSeek released its cheap and serviceable V3 model early last year, it sent shockwaves throughout Silicon Valley and beyond, roiling the stock market, shaking political confidence in American AI, and stoking new fears from the ever-churlish China hawks. A year later, DeepSeek is preparing to launch its new V4 model — a development which could have major implications for US tech companies and the firms backing them. According to a CNBC bulletin, DeepSeek’s latest version is “expected to be imminent” given the release-schedule of previous versions. Depending on…

Well over a decade over it first came out in theaters in 2012, Prometheus — director Ridley Scott’s return to the Alien universe — is the number one movie on Netflix, according to FlixPatrol, which keeps tabs on these sorts of things even if streamers like Netflix don’t share all their data. Prometheus was added to Netflix in several countries in February, and clearly, people were eager to buy what it was selling. Prometheus’ newfound popularity provides a good excuse to look back on this ambitious, strange, divisive movie. Prometheus still works all these years later The sci-fi action epic…
