In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves ...

Neuroscience has traditionally explained communication in the brain through electrochemical signaling: action potentials, synapses, neuromodulators, and ...

For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

During a deeply inelastic collision with a proton, a relativistic electron (highlighted in blue) can emit a high-energy photon (purple here) that penetrates interior of the proton, where it ‘sees’ ...

3D reconstruction of the electromagnetic field surrounding a magnesium oxide nanocube. The three modes (I, II, III) represent the nanocube’s different energy ...

ALBERT EINSTEIN won the 1921 Nobel prize for physics in 1922. The temporal anomaly embodied in that sentence was not, alas, one of the counterintuitive consequences of his theories of relativity, ...

China’s Large High Altitude Air Shower Observatory (LHAASO)–one of the country’s key national science and technology infrastructure facilities–has found a dozen ultra-high-energy (UHE) cosmic ...
