How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the first, very rapid expansion of the universe, would have taken place...
Quantum key distribution (QKD) harnesses the power of quantum mechanics to securely transmit confidential information. When an outside source eavesdrops on a QKD transmission, the quantum states are affected. This dependably alerts the receiver and sender that the...
A research team led by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has used the Tianma Radio Telescope to conduct multi-band radio observations of the returning comet 12P/Pons-Brooks (12P). They measured its water production rate during...
Researchers have achieved a breakthrough in solar physics by providing the first direct evidence of small-scale torsional Alfvén waves in the sun’s corona—elusive magnetic waves that scientists have been searching for since the 1940s. Go to Source
