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.....»»
Could this supermassive black hole only have formed by direct collapse?
Nearly every galaxy in the universe contains a supermassive black hole. Even galaxies that are billions of light years away. This means supermassive black holes form early in the development of a galaxy. They are possibly even the gravitational seeds.....»»

Two types of ultrafast mode-locking operations generation from an Er-doped fiber laser based on germanene nanosheets
Saturable absorbers as passive modulators in passively mode-locked fiber lasers play a crucial role in the generation of ultrashort pulses. Germanene, a graphene-like two-dimensional material with fast carrier relaxation time and large nonlinear abso.....»»
Report: Halogenated greenhouse gases still being emitted in Germany
In the past, they were found in every refrigerator and aerosol until it was discovered that they had ripped a hole in the ozone layer protecting Earth's atmosphere: chlorofluorocarbons, in short CFCs......»»
Fiber optic sensing tracks seismicity from injected carbon dioxide at Australian site
Researchers at a field site in Victoria, Australia are among the first to use fiber optic distributed acoustic sensing (DAS) for high-precision tracking of induced seismicity from a small carbon dioxide (CO2) injection, according to a new study publi.....»»
Oppenheimer Almost Discovered Black Holes Before He Became "Destroyer of Worlds"
Before leading the Manhattan Project, J. Robert Oppenheimer co-authored a paper explaining that the most massive stars must eventually become what we would now call a black hole.....»»
Finding game-changing superconductors with machine learning tools
Superconductors—found in MRI machines, nuclear fusion reactors and magnetic-levitation trains—work by conducting electricity with no resistance at temperatures near absolute zero, or -459.67°F......»»
4 questions Secret Invasion is forcing me to ask about the Avengers

James Webb spots the most distant active supermassive black hole ever discovered
A very early example of a supermassive black holes was recently discovered, dating back to just 570 million years after the big bang......»»
Webb detects most distant active supermassive black hole to date
It's a bonanza: The universe is absolutely teeming with black holes. Researchers have long known this, but less massive black holes that existed in the early universe were too dim to detect—that is until the James Webb Space Telescope began taking.....»»
Testing of wind sensing in rats shows sub-orbital whiskers play a role in assessing direction
A team of neurobiologists and neuroscientists at the Woods Hole Marine Biological Laboratory has found that sub-orbital whiskers play a role in helping rats determine which direction air movement is coming from and to respond accordingly. In their pa.....»»
Webb Telescope detects most distant active supermassive black hole
Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope (JWST). The galaxy, CEERS 1019, existed about 570 million years after the big bang, and its black hole is less massive than any ot.....»»
