Wegovy Users Have 5x Higher Vision Loss Risk Than Ozempic, New Study Finds
A new study found that users of Wegovy have nearly five times the risk of ischemic optic neuropathy (ION), compared to Ozempic users. ION, also known as 'eye stroke', is a condition that happens due to reduced blood flow to the optic nerve.

Xiaomi's Futuristic Modular Optical System Enters Production a Year After MWC 2025 Showcase, Tipster Claims
Xiaomi’s magnetic modular lens system for phones was first teased as a concept at MWC 2025. While Xiaomi remain tightlipped about its launch, a new leak says it has entered the mass-production planning phase. It is said to arrive later this year. The Xiaomi Modular Optical System integrates the optical capabilities of a professional camera with t...

Scientists Develop Tiny Multi-Layer Lenses for High-Performance Portable Optics
Learn about the innovative multi-layer metalens design and its potential applications in portable devices. It is the first-ever discovery which would allow people to see the world differently. Unlike traditional lenses, these are fabricated by stacking together multiple thin layers of so-called metamaterials rather than using a single one.

World’s First Modular Quantum Computer Operates at Room Temperature
A room-temperature quantum computer has been developed by Xanadu, addressing scalability and error correction challenges in the field. Named Aurora, the system uses photonic qubits and connects multiple modules via fibre optics, removing the need for extreme cooling. Published in Nature, the study highlights its potential for large-scale quantum da...
