The National Security Agency has produced hundreds of pages of historical UAP-related records following a Freedom of Information Act appeal by the Disclosure Foundation. Many of the records were previously classified “TOP SECRET UMBRA,” one of the most sensitive classification markings associated with signals intelligence.
In the letter, EZ Lynk lawyers wrote that Apple and Google are planning to fight the subpoenas. Walmart declined to comment. None of the other companies subpoenaed responded to a comment request.
“These requests for potentially hundreds of thousands of people’s PII go well beyond the needs of this case and create serious privacy concerns,” wrote EZ Lynk’s lawyers in the letter. “Investigating this claim does not require identifying each person who has used the product.”
The government said in the letter its request for data was fair and appropriate, and it had “consistently sought customer information” because its lawyers want to interview witnesses about their use of EZ Lynk’s technology. It has already presented evidence to the court of people using the company’s tools to remove emissions controls on their cars, including Facebook and EZ Lynk forum posts outlining that use of the product.
Smart rings are no longer novel. A few hidden superpowers, however, might make them interesting again.
Most devices are increasingly focused on biometric tracking. The Aivela Ring Pro aims to stand out with stealth gesture and touch controls. With a stealth flick, swipe or slide of the finger, you can control music playback, adjust volume, trigger the camera, advance slide decks, scroll and more on your phone.
Launched at CES 2026, the Ring Pro resembles many of its competitors, including the Oura Ring and Samsung’s Galaxy Ring. There’s only so much you can do with ring design after all. It has the familiar metallic (scratch-resistant) finish, a slightly thicker top profile and sensors lining the interior. The primary visual cue indicating something different is a small diamond-shaped engraving at the center, which signals the location of the touchpad.
Researchers at Boise State University have developed a breakthrough in wearable electronics: a multifunctional electronic tattoo (e‑tattoo) that integrates energy harvesting, energy storage, and real‑time biometric sensing into a single, skin‑conformal platform.
The innovation leverages electrospun poly(vinyl butyral‑co‑vinyl alcohol‑co‑vinyl acetate) (PVBVA) fibers coated with titanium carbide (Ti₃C₂Tₓ) MXenes, offering a scalable, biocompatible, and durable alternative to conventional wearable devices that often rely on rigid substrates or external gels.
The work is published in the journal Advanced Science.
WhatsApp is rolling out passkey-encrypted backups for iOS and Android devices, enabling users to encrypt their chat history using their fingerprint, face, or a screen lock code.
Passkeys are a passwordless authentication method that allows users to sign in using biometrics (such as face recognition or fingerprint), PINs, or security patterns instead of traditional passwords. They enable logging into websites, online services, or apps without needing to remember complex passwords or use a password manager.
When creating a passkey, your device generates a unique cryptographic key pair consisting of a private key stored on the device and a public key sent to the website or app. Because of this, passkeys provide significantly improved security over regular credentials, seeing that they can’t be stolen in data breaches because the private key never leaves your device.
Introduction.
Grounded in the scientific method, it critically examines the work’s methodology, empirical validity, broader implications, and opportunities for advancement, aiming to foster deeper understanding and iterative progress in quantum technologies. ## Executive Summary.
This work, based on experiments conducted in 1984–1985, addresses a fundamental question in quantum physics: the scale at which quantum effects persist in macroscopic systems.
By engineering a Josephson junction-based circuit where billions of Cooper pairs behave collectively as a single quantum entity, the laureates provided empirical evidence that quantum phenomena like tunneling through energy barriers and discrete energy levels can manifest in human-scale devices.
This breakthrough bridges microscopic quantum mechanics with macroscopic engineering, laying foundational groundwork for advancements in quantum technologies such as quantum computing, cryptography, and sensors.
Overall strengths include rigorous experimental validation and profound implications for quantum information science, though gaps exist in scalability to room-temperature applications and full mitigation of environmental decoherence.
Framed within the broader context, this award highlights the enduring evolution of quantum mechanics from theoretical curiosity to practical innovation, building on prior Nobel-recognized discoveries like the Josephson effect (1973) and superconductivity mechanisms (1972).
ControlVault3 firmware vulnerabilities impacting over 100 Dell laptop models can allow attackers to bypass Windows login and install malware that persists across system reinstalls.
Dell ControlVault is a hardware-based security solution that stores passwords, biometric data, and security codes within firmware on a dedicated daughterboard, known as the Unified Security Hub (USH).
The five vulnerabilities, reported by Cisco’s Talos security division and dubbed “ReVault,” affect both the ControlVault3 firmware and its Windows application programming interfaces (APIs) across Dell’s business-focused Latitude and Precision laptop series.
