The Aurora uses metallic uranium fuel pellets, which are denser, more thermally resistant, and cheaper to produce than the uranium dioxide pellets used in tra...

U.S. Researchers Achieve Breakthrough in Quantum Internet Transmission Over Ordinary Cable

U.S. Researchers Achieve Breakthrough in Quantum Internet Transmission Over Ordinary Cable

Researchers led by a team at the U.S. National Institute of Standards and Technology (NIST) have successfully transmitted entangled photons over 62 kilometers (38.5 miles) of ordinary fiber-optic cable without breaking their entanglement. This achievement marks a significant step towards the development of a quantum internet. The experiment was conducted using existing network cabling, much of which was strung above ground and exposed to environmental factors like wind, temperature changes, and vibrations from traffic. These conditions typically distort the quantum states of entangled particles. To overcome this interference, the researchers employed a laser light signal as a reference point, calculating its twisting to apply necessary corrections to the entangled photons. This method allowed for 92.8% of the operation time to be used for sending stabilized quantum information. The findings have been published in the Journal of Optical Communications and Networking.

New Microscope Technology Captures Super-Resolution Images of Internal Cell Structures

New Microscope Technology Captures Super-Resolution Images of Internal Cell Structures

A new experimental framework, named REID (Reaction-Enabled Imaging), has been developed to capture super-resolution images of internal cell structures at approximately 100 nanometers. This technology, detailed in Nature, utilizes the cells' own chemical glow rather than external lasers, which can be damaging. Researchers discovered that by swapping a common chemical co-reactant for a biological buffer called Bis-Tris, the cellular glow was boosted by 1,000 times, allowing for sharp, unblurred images in just 20 milliseconds. REID combines computer algorithms with electricity-triggered, chemical, and biological luminescence to enhance image clarity. It has successfully built a 3D map of a cell's skeleton, resolving structures 116 nanometers apart horizontally and 235 nanometers apart vertically, and has captured proteins on cell surfaces with high sensitivity. This method is significantly gentler on cells compared to traditional laser-based microscopes, enabling continuous, high-quality footage for extended ...

Federal Agencies Warn of Active Threat: Hackers Using AI-Generated Code to Target Critical Infrastructure

Federal Agencies Warn of Active Threat: Hackers Using AI-Generated Code to Target Critical Infrastructure

Five U.S. federal agencies—the National Security Agency (NSA), Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Department of Energy (DOE), and Environmental Protection Agency (EPA)—have issued a joint alert regarding an 'active threat' to critical infrastructure. Attackers are reportedly using AI-generated exploitation scripts to breach internet-exposed Siemens S7 Series programmable logic controllers (PLCs). These PLCs are vital components in critical manufacturing, energy, water and wastewater, chemical, food and agriculture, and commercial facilities. The attackers leverage open-source industrial automation libraries, specifically snap7.dll/python-snap7, in conjunction with AI coding assistants to create custom tools. These tools mimic operational technology (OT) monitoring software, granting them read/write access to PLC memory, configuration data, and ladder logic programs via the S7comm protocol. While the alert does not attribute the threats to a speci...
