A pair of researchers at Applied Physics has created what they describe as the first general model for a warp drive, a model for a space craft that could travel faster than the speed of light, without actually breaking the laws of physics. Alexey Bobrick, and Gianni Martire have written a paper describing their ideas for a warp drive and have…

Researchers investigate ‘imaginary part’ in quantum resource theory
Recently, a research team led by academician Guo Guangcan from CAS Key Laboratory of Quantum Information of the University of Science and Technology of China (USTC) of CAS, has made important progress in quantum information theory. Prof. Li Chuanfeng and Prof. Xiang Guoyong from the team collaborated with Dr. Strelstov from University of Warsaw to investigate the imaginary part of quantum…
Neanderthal ears were tuned to hear speech just like modern humans
Virtual reconstructions of Neanderthal ears show that our extinct cousins had the same physical capacity for hearing as modern humans, and so could probably also make the same sounds we can – although whether they actually spoke a language is still unknown Source: https://www.newscientist.com/article/2269577-neanderthal-ears-were-tuned-to-hear-speech-just-like-modern-humans/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Through the looking glass: Artificial molecules open door to ultrafast polaritonic devices
Researchers from Skoltech and the University of Cambridge have shown that polaritons, the quirky particles that may end up running the quantum supercomputers of the future, can form structures behaving like molecules—and these “artificial molecules” can potentially be engineered on demand. The paper outlining these results was published in the journal Physical Review B. …
Why an Animated Flying Cat With a Pop-Tart Body Sold for Almost $600,000
In the 10 years since Chris Torres created Nyan Cat, an animated flying cat with a Pop-Tart body leaving a rainbow trail, the meme has been viewed and shared across the web hundreds of millions of times. On Thursday, he put a one-of-a-kind version of it up for sale on Foundation, a website for buying and selling digital goods. In the…
Researchers discover mechanism behind influence of irradiation defects on tritium permeation barrier
Recently, researchers led by Prof. Zhou Haishan from the Institute of Plasma Physics (ASIPP) of the Hefei Institutes of Physical Science (HFIPS) reported their new findings about the influence of irradiation effects on hydrogen permeation through alpha-alumina (α-Al2O3) tritium permeation barrier (TPB). …
Astrophysicists design ‘radically different’ world map
You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round. Source: https://earthsky.org/earth/astrophysicists-new-design-world-map…
World’s first video of a space-time crystal
A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope Maxymus at Bessy II at Helmholtz Zentrum Berlin, they were able to film the recurring periodic magnetization structure in a crystal. Published in the Physical Review Letters, the research project was a collaboration between…
Ion-optics-based quantum microscope can image individual atoms
A team of researchers at Universität Stuttgart has developed an ion-optics-based quantum microscope that is capable of creating images of individual atoms. In their paper published in the journal Physical Review Letters, the group explains how they built their microscope and how well it worked when tested. …
Scientists claim that all high-energy cosmic neutrinos are born by quasars
Scientists of the P. N. Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), the Moscow Institute of Physics and Technology (MIPT) and the Institute for Nuclear Research of RAS (INR RAS) have studied the arrival directions of astrophysical neutrinos with energies more than a trillion electronvolts (TeV) and came to an unexpected conclusion: all of them are born…
