Technology Update
Linux Kernel Bug Could Elevate Privileges
A Linux kernel vulnerability could allow an attacker with only ordinary user privileges to seize the system’s highest-level administrator, or root, privileges which could affect the latest Android devices.
Cyber Threat Without Hacking into a System
A new vulnerability could allow hackers to target and disrupt critical infrastructure such as water treatment plants and energy grids without needing to break into a facility’s own systems or crack its encryption.
Safety Checks Approved for MARVEL Reactor
Department of Energy’s (DoE) MARVEL microreactor project cleared more safety milestones as Idaho researchers prepare the reactor for initial startup tests this winter.
Vulnerable OS File-notification Systems
There are security risks in the file notification systems of the widely used operating systems Windows, Linux, Android and macOS and through side-channel attacks, system-wide changes to files, keystrokes and visited websites can end up tracked. Additionally, password prompt windows can end up spoofed to intercept password entries.
Operating Reactor on Lower Enriched Nuclear Fuel
Belgium’s nuclear research center, SCK CEN, submitted a safety assessment to regulators for clearance to operate the BR2 research reactor on a lower enriched uranium fuel.
Making Smart Cars Safer
As has been said multiple times over the past decade or so, modern vehicles are computers on wheels, powered by complex software and artificial intelligence. As those systems take on more responsibility, they must process information quickly and reliably enough to keep critical functions running safely.
Smarter, Smaller Microsensor to Detect Dangerous Gas
Adding layers of complication to any project can lead to more things that could potentially go wrong – and they often do.
Sensor Detects Finite Nuclear Materials
A new type of monitor is in development that can check every minute or even every second for the buildup of nuclear material in the air ducts of nuclear fuel cycle facilities.
Giving Robots a Gentle Touch
Robots can lift car engines with brute force, yet they routinely crush a soft berry or drop a slippery glass because they cannot feel the delicate boundary between a secure grip and destructive pressure.
Graphene Diffraction to Secure Electronic Systems
Modern electronic systems depend on reliable ways to confirm a device is genuine. While, conventional security methods often rely on stored digital keys or software-based credentials, these approaches are powerful, but they can become vulnerable if the stored information ends up copied, leaked, or reproduced by an attacker.
Securing Chips From Extreme Heat to Cold
A car engine block, an orbiting satellite, and an uninsulated factory sensor all share a hidden vulnerability: intense heat quietly scrambles the electronic locks that safeguard the connected world.
AI Framework for Safely Controlling Fusion
Inside some fusion energy systems, particles hotter than the core of the sun can become unruly in a few thousandths of a second, far faster than any human operator can react.
Reinventing Nuclear Fuel Recycling
For decades, we have treated used nuclear fuel as high-level waste to be buried and forgotten, but wait a minute, it could be possible to use it as a power source.
Understanding Dust in Emergency Environment
Being prepared for an emergency is key to keeping everyone and everything safe. This means more than just having supplies, sometimes the most important preparation is having the right data to help first responders and the community stay safe.
Cyborg Cockroaches Learn to Navigate
Cyborg insects combine the mobility of living organisms with miniature electronic devices, offering potential applications in search-and-rescue operations, infrastructure inspection, and exploration of environments that are difficult for conventional robots.
Smart Highways Need Stronger Protection
Highways people use to go to school, work, or shopping truly depends on networked systems using optical fiber, sensors, video cameras, and programmable logic controllers (PLCs).
Device Detects Ammonia Leaks as Low as 1PPM
An ultrasensitive ammonia gas sensor using an environmentally friendly, lead-free perovskite material is now in development.
Device can Take Over Aircraft’s Computer
No ever thought physical access to an aircraft was a cybersecurity risk; but that line of thinking may soon change as it could be possible to take over communications between onboard computers.
Teaching AI not to Hallucinate
Multimodal large language models (MLLMs), which process multiple types of sensory information such as text, images, and audio at the same time, are rapidly expanding the range of applications for artificial intelligence (AI).
Malicious SIMs can Capture Smartphones
Subscriber Identity Modules (SIMs), the secure element used to connect devices to a mobile network, can pose severe security risks.
