BepiColombo Spacecraft Prepares for Mercury Arrival After Eight-Year Journey

After eight years of interplanetary travel, the ESA/JAXA BepiColombo mission is set to begin its Mercury Arrival Phase. On September 3, 2026, the Mercury Transfer Module (MTM) will separate from BepiColombo's two science orbiters — the first major step in what ESA describes as one of the most

Researchers May Have Detected Quantum Vacuum Effects on Light Polarization

Physicists report they may have directly observed a subtle quantum effect where seemingly empty space influences how light travels through it. The phenomenon, known as vacuum birefringence, is a prediction of quantum electrodynamics (QED) — the theory describing how light and matter interact at the quantum scale. According to the theoretical

NASA Tests GPS-Free Navigation System Using Space Debris as Landmarks

NASA has completed a successful test of a navigation system that enables satellites to determine their position in space without depending on GPS signals. The system, called FALCON (Flight Algorithm for Satellite Localization using Cooperative Navigation), leverages other spacecraft and orbital debris as landmarks to calculate precise positioning. The test

London Surgeons Complete World's First Live AI-Assisted Brain Tumor Removal

A team of neurosurgeons in London has achieved a medical milestone by completing the world's first live AI-assisted brain surgery. The procedure involved the removal of a brain tumor from a patient while an artificial intelligence system provided real-time guidance to the surgical team. The AI system was

How Climate Change Is Destabilizing Nepal's Glaciers and Increasing Flood Risks

Rising global temperatures are fundamentally altering the landscape of the Hindu Kush Himalayan region, with particularly dangerous consequences for Nepal. According to climate researchers, warmer conditions are causing glaciers to retreat at an accelerating rate while simultaneously destabilizing the remaining ice structures. The retreating glaciers leave behind unstable terrain and

Generative AI Gets a Chemistry Lesson: Valence Constraints Improve Materials Discovery

Generative AI models are increasingly being applied to materials science, but designing computationally stable and chemically plausible new materials remains a significant challenge. A new approach reported in Nature addresses this by embedding valence constraints directly into the generative modeling process. Valence rules—the constraints that govern how atoms bond—
