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.....»»
Saturday Citations: Scientists study monkey faces and cat bellies; another intermediate black hole in the Milky Way
This is not a rerun of last week's roundup; another group of astronomers found a second intermediate-mass black hole in the Milky Way and I can't avoid highlighting it. They're cool! They may have formed in the primordial universe, they comprise the.....»»
Deeper down the rabbit hole: How technology conspiracy beliefs emerge and foster a conspiracy mindset
As technology proliferates, misinformation and conspiracy theories seem to flourish. Conspiracy beliefs specifically about technology include popular commercial technologies, such as Amazon Echo and Google Search, as well as non-profit technologies d.....»»
Another intermediate-mass black hole discovery at the center of our galaxy
While researching a cluster of stars in the immediate vicinity of the supermassive black hole SgrA* (Sagittarius A*) at the center of our galaxy, an international team of researchers led by PD Dr. Florian Peißker has found signs of another, intermed.....»»
Nanoscale trilayer exhibits ultrafast charge transfer in semiconductor materials
Successfully innovating optoelectronic semiconductor devices depends a lot on moving charges and excitons—electron-hole pairs—in specified directions for the purpose of creating fuels or electricity......»»
Q&A: "We lost instruments chewed or crunched by bears and sea otters"—how a researcher listens for elusive belugas
Dr. Manuel Castellote studies the behavior and conservation of whales and dolphins. After beginning his academic career in Spain, he now works in the United States, applying acoustic techniques to learn more about cetaceans—especially beluga whales.....»»
Q&A: What past environmental success can teach us about solving the climate crisis
Susan Solomon, MIT professor of Earth, atmospheric, and planetary sciences (EAPS) and of chemistry, played a critical role in understanding how a class of chemicals known as chlorofluorocarbons were creating a hole in the ozone layer......»»
Saturday Citations: The first Goldilocks black hole; Toxoplasma gondii metabolism; pumping at the speed of muscle
This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard......»»
Exploring three-dimensional quantum Griffiths singularity in bulk unconventional iron-based superconductors
Exploration of exotic quantum phase transitions has always been a focus in condensed matter physics. Critical phenomena in a phase transition are entirely determined by the universality class, which is controlled by the spatial and/or order-parameter.....»»
Hubble finds evidence for rare black hole in Omega Centauri
An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster i.....»»
Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
Hubble finds mysterious and elusive black hole
For years, astronomers have been searching for elusive intermediate-mass black holes. Now, Hubble has found evidence of one in Omega Centauri......»»
Nearby star cluster houses unusually large black hole

Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
Novel two-step electrolysis of water proposed for hydrogen production
A research team led by Prof. Chen Changlun from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, together with collaborators, developed advanced cobalt-doped nickel hydroxide bipolar electrodes and non-noble metal catalyst.....»»
Swarm of dusty young stars found around our galaxy’s central black hole
Stars shouldn't form that close to the black hole, so these would need explaining. Enlarge / The Milky Way's central black hole is in a very crowded neighborhood. (credit: UMass/D.Wang/NASA/STScI) Supermassive black hole.....»»
X-ray binary Swift J1727.8-1613 has a large relativistic jet, observations show
Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly extended and bright relativi.....»»
Simulations demonstrate potential mechanisms of intermediate-mass black hole formation in globular clusters
Joint research led by Michiko Fujii of the University of Tokyo demonstrates a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed st.....»»
