An international team of physicists from Germany and Japan has made the most precise measurement yet of the proton’s atomic mass. The result is a factor of three more precise compared to the current literature value, however shifted by about three standard deviations. Proton is a subatomic particle found in …

A group of researchers from the Australian National University (ANU) and elsewhere has designed a nanoantenna — a device which is 100 times thinner than a human hair — that promises ultra-fast rendering of high-definition graphics on gaming consoles. The device is described in a paper published in the journal …

A Princeton-led team of researchers has discovered a revolutionary way to generate high-energy shock waves in the lab. Peering deep into the core of the Crab Nebula, this Hubble image reveals the beating heart of one of the most historic and intensively studied remnants of a supernova, an exploding star. The …

A team of computer scientists and electrical engineers at the University of Washington has invented a cellphone that requires no batteries and harvests power from either ambient radio signals or light. The device is described in a paper published in the Proceedings of the Association for Computing Machinery on Interactive, …

A Stanford-led research team has captured the freezing of water, molecule-by-molecule, into a super-dense, exotic form of ice called ice VII. The results are published in the journal Physical Review Letters. Experimental configuration of the X-ray Free Electron Laser probe and optical laser; the shock freezing behavior of water captured …

The LHCb (Large Hadron Collider beauty) collaboration at CERN’s Large Hadron Collider in Switzerland has reported the observation of a doubly charmed particle. The particle, called the ?cc++, is a baryon containing two charm quarks and one up quark. The doubly charmed baryon ?cc++ contains two charm quarks and one …

New research led by Paris Diderot University offers a view into the inner workings of the ‘mind’ of Maxwell’s demon, a famous thought experiment in physics. Sketch of the quantum Maxwell demon experiment: (A) after preparation (step 1) in a thermal or quantum state by a pulse at frequency fs, …

In a paper published in the Journal of Cosmology and Astroparticle Physics (arXiv.org preprint), German physicists investigate the effects due to Universe’s extra dimensions — the existence of which is a critical but as yet unproven element of string theory — on ‘ripples’ in the fabric of space and time …

By focusing laser light to brightness one billion times greater than the surface of the Sun, a team of physicists from the United States and China has observed changes in a vision-enabling interaction between light and matter. Those changes yielded unique X-ray pulses with the potential to generate extremely high-resolution …

A Stockholm University-led team of physicists has discovered two low-temperature phases of liquid water with large differences in structure and density. An artist’s impression of the two forms of ultra-viscous liquid water with different density; on the background is depicted the X-ray speckle pattern taken from actual data of high-density …
