3D Thermal Cloak Can Hide Objects from Infrared Cameras
Scientists have developed a three-dimensional thermal invisibility cloak capable of concealing objects from infrared cameras, according to new research reported by ScienceDaily.
Space Waves Reveal Earth's Magnetic Shield Is Hit Hardest in Winter
A new study by researchers from the United States and Finland shows that Kelvin–Helmholtz waves at the boundary of Earth's magnetosphere are asymmetric, with the winter hemisphere absorbing the strongest solar-wind pressure — a finding that could sharpen space-weather forecasting.
Arctic Winter Sea Ice Could Be Far Worse Than Models Predict
A new study using chemical biomarkers from 6,000-year-old Arctic sediments found that existing climate models overestimated winter sea-ice coverage during a past warm period, suggesting future Arctic winter ice loss could exceed earlier projections by about one million square kilometres.
Silicon Quantum Bits Hit 99.99% Accuracy While Running Five at Once
Researchers at RIKEN in Japan have demonstrated five silicon spin qubits operating simultaneously with fidelity above 99.9%, and three of those qubits exceeding 99.99%, by identifying and correcting a quantum interference effect that previously degraded parallel performance.
