Acoustic plasmons found in hole-doped cuprate superconductors
The presence of acoustic plasmons in p-type (hole-doped) cuprate superconductors has now been confirmed by Dr. Ke-Jin Zhou and his team using high-resolution RIXS (Resonant Inelastic X-ray Scattering), at Diamond Light Source's I21 beamline. This dis.....»»
Supercomputer simulations reveal the nature of turbulence in black hole accretion disks
Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called accretion disks surrounding black holes, using state-of-the-art supercomputers to conduct the h.....»»
Dark matter could have helped make supermassive black holes in the early universe
It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out—a process that can take.....»»
Event Horizon Telescope can now take images of black holes that are 50% sharper
The Event Horizon Telescope, which took the first ever image of a black hole, has made the highest ever resolution observations taken from the Earth's surface......»»
How to control your screen time and make technology work for you
Many of us feel that we, or our children, spend too much time staring at a screen. From gaming to social media use or "doomscrolling," it can sometimes feel that we are mindlessly spending hours going down a rabbit hole of technology......»»
Sound drives "quantum jumps" between electron orbits
Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be.....»»
Watch a star get destroyed by a supermassive black hole in the first simulation of its kind
Giant black holes in the centers of galaxies like our own Milky Way are known to occasionally munch on nearby stars......»»
Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's accretion disk, where infa.....»»
Supercomputer simulations offer explanation for X-ray radiation from black holes
Researchers at the University of Helsinki have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from black hole surroundings. The radiation originates from the combined effect of the chaotic movements of ma.....»»
NASA telescopes work out black hole"s feeding schedule
By using new data from NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory as well as ESA's XMM-Newton, a team of researchers has made important headway in understanding how—and when—a supermassive black hole obtains and then cons.....»»
Scientist performs the first nonlinear study of black hole mimickers
In recent research, a scientist from Princeton University has performed the first nonlinear study of the merger of a black hole mimicker, aiming to understand the nature of gravitational wave signals emitted by these objects, which could potentially.....»»
Astronomers ask public to help find newly formed black holes
The Dutch Black Hole Consortium has launched an eight-language version of the BlackHoleFinder app that citizens all over the world can use to help identify newly formed black holes. Previously, the app was only available in Dutch and English......»»
Apple has closed an ancient macOS Safari security hole
Apple is fixing a vulnerability in Safari for macOS, that seems to date back to the dawn of Intel Macs.Icon for Safari in macOSThe Defcon hacking conference is taking place from August 8 to August 11 in Las Vegas, which hosts talks about newly discov.....»»
Team fabricates world"s highest-performance superconducting wire segment
Our future energy may depend on high-temperature superconducting (HTS) wires. This technology's ability to carry electricity without resistance at temperatures higher than those required by traditional superconductors could revolutionize the electric.....»»
New study reviews progress in ternary hydrogen-rich superconductors
Room-temperature superconductivity has been a century-long-held dream of scientists. Hydrogen-rich compounds at high pressures are predicted to be potential high-temperature and even room-temperature superconductors and have become one of the superco.....»»
There’s one gaping hole in the Windows Arm app ecosystem
Adobe has launched Illustrator for Windows on Arm in beta, but one important app has been left behind......»»
Ce-doped yttria transparent ceramic: A new ultraviolet-shielding material for extreme conditions
Ultraviolet (UV) radiation can break most of the chemical bonds in organic matter, and prolonged exposure to ultraviolet light can cause significant harm to humans and objects. In response, UV-shielding materials have been developed to fulfill variou.....»»
New study uses self-interacting dark matter to solve the final parsec problem
In a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter......»»
Research shows the ocean is becoming too loud for oysters
Baby oysters rely on natural acoustic cues to settle in specific environments, but new research from the University of Adelaide reveals that noise from human activity is interfering with this critical process......»»
Researchers develop novel procedure for isolating primary mouse hepatocytes with holographic acoustic tweezers
Recently, a research team established a comprehensive procedure for isolating primary mouse hepatocytes and maintaining them in long-term culture with significant amplification in a two-dimensional (2D) environment. The team was led by Prof. Li Fei a.....»»
