Researchers at the Niels Bohr Institute, University of Copenhagen, in collaboration with the University of Konstanz and ETH Zurich, have managed to get vibrations to travel around this membrane, almost without any loss. In fact, so little loss that it is far better than even electronic circuit signal handling. The result is now published in the journal Nature.
Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum world. This second law of entanglement manipulation proves that, just like heat or energy in an idealised thermodynamics regime, entanglement can be reversibly manipulated, a statement which until now had been heavily contested. The new research – released on July 2, 2025 in Physical Review Letters – deepens understanding of entanglement’s basic properties and provides critical fundamental insight into how to efficiently manipulate entanglement and other quantum phenomena in practice.
Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made a significant breakthrough in photocatalysis by unveiling a “super” photoreductant, marking a major advancement in organic synthesis.
Peak performance in elite sport relies on a myriad of physical and mental capacities – and now there is an increasing consideration of the role of good sleep for training and competition performance.
A new study led by Flinders University sleep experts in collaboration with Lumin Sports uses data from Garmin smartwatches and other monitoring technology to explore sleep, wellbeing and performance of elite male cyclists competing in the world’s most famous bike race – the Tour de France.
In this work, we present a cost-effective, lithography-free, wafer-scale thermal emitter with angle- and polarization-selective dual-wavelength narrowband characteristics enabling infrared information encryption and decryption.
