SAN FRANCISCO – NASA continues to face difficulties in sending some of its payloads to orbit as hosted payloads on commercial satellites. The space agency is looking for a geostationary commercial satellite to house the Geostationary Carbon Cycle Observatory or GeoCARB, an instrument to measure carbon dioxide, carbon monoxide and methane over North and South

Snapshots from depth-resolved movies at progressively increasing scene depths. (Courtesy: Daan Stellinga) A new three-dimensional imaging system uses multimode optical fibres (MMFs) rather than traditional bulk optics, paving the way for applications in medical imaging. The system can scan a scene at a rate of nearly 23 000 points per second over depths of up to

An artistic depiction of both works. In the background: spin liquids. (Courtesy: Google Quantum AI) Physicists have measured long-range quantum entanglement in special, topologically ordered phases of matter for the first time. This feat, which was achieved independently by two research groups using coupled superconducting circuits and arrays of atoms, could aid the development of
