Artemis II Crew Honored for Historic Lunar Flight The four astronauts of NASA's Artemis II mission have been honored after completing the first crewed lunar flight in over 50 years,

Researchers Uncover Prompt Injection Vulnerability in AI Memory Systems

Attack Exploits AI Memory Persistence Security researchers have identified a vulnerability that allows attackers to embed hidden instructions within AI systems that persist across conversation sessions. The technique, known as a prompt injection attack targeting memory, enables a single crafted prompt to introduce instructions that the AI will follow in

Early-Life Sugar Restriction May Lower Dementia Risk Decades Later, Study Suggests

A growing body of research is examining how early-life nutrition shapes long-term brain health. A new study published in PLOS ONE leverages a unique historical experiment—World War II sugar rationing in the United Kingdom—to explore the connection between childhood sugar exposure and dementia risk decades later. The researchers

NASA Satellites Successfully Test GPS-Free Navigation Technology

The Experiment A team of NASA satellites has successfully proven that spacecraft can navigate through space without relying on the Global Positioning System. The demonstration, described as the world's first "lost-in-space" GPS-free navigation experiment, showed that satellites can accurately determine their orbital position using alternative methods.

Quantization-Aware Healing: When 4-Bit Compression Beats Full-Precision Models

The Promise of Compression Without Compromise Model quantization—reducing the numerical precision of neural network weights from 32-bit or 16-bit floats to 4-bit or even lower—has long been a key strategy for deploying large models on resource-constrained hardware. The conventional wisdom holds that this compression comes at a cost:
