Comet

NASA discovered that a near-Earth asteroid, observed for nearly 30 years, is actually a comet. This reclassification could aid future planetary defense efforts.

NASA scientists identified a near-Earth object as a comet due to its irregular motion, despite prior images suggesting it was an asteroid. The study, conducted by NASA’s Jet Propulsion Laboratory, used precise tracking and powerful observatories to confirm its dual nature.

BioShocking is an attack technique that manipulates AI-powered browsers into bypassing safety guardrails by immersing them in fictional scenarios, leading to the extraction of sensitive data like credentials. The method exploits how AI agents in 'agent mode' inherit user-authenticated contexts, making them vulnerable to goal-manipulation attacks that trick them into performing harmful actions.
