Cooling radio waves to their quantum ground state Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use in detecting ultra-weak magnetic resonance (MRI) signals or for quantum-sensing applications that can help the search for dark matter. The results have been published in Science Advances.
Machine-learning system accelerates discovery of new materials for 3D printing The growing popularity of 3D printing for manufacturing all sorts of items, from customized medical devices to affordable homes, has created more demand for new 3D printing materials designed for very specific uses.
Scientists find evidence the early solar system harbored a gap between its inner and outer regions In the early solar system, a "protoplanetary disk" of dust and gas rotated around the sun and eventually coalesced into the planets we know today.
