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.....»»
Black hole ripples could help pin down expansion of universe
The echoes of light from jets launched from black holes offers a new way to pin down the distance to these exotic objects and to study a largely unobserved population in the center of the Galaxy. It could also even help determine the rate of expansio.....»»
SpaceCamp, the amazing 1986 film, is stuck in a streaming black hole

Astronomers witness energetic switch on of black hole
A team of astronomers led by researchers from the University of Birmingham, University College London and Queen's University Belfast have discovered one of the most dramatic 'switches on' of a black hole ever seen. They will present their findings on.....»»
Using a detector the size of a galaxy, astronomers detect gravitational waves from supermassive black hole pairs
When black holes and other enormously massive, dense objects whirl around one another, they send out ripples in space and time called gravitational waves. These waves are one of the few ways we have to study the enigmatic cosmic giants that create th.....»»

If Apple Vision Pro wasn"t expensive enough, a customizer has one for 10x more
If you were disappointed that Apple Vision Pro costs only $3,500 and have money burning a hole in your pocket, a customizer has a $40,000 treat for you with gold trim and a leather head mount.For the Apple Vision Pro buyer who has, if not everything,.....»»
Giant "Gravity Hole" in the Ocean May Be the Ghost of an Ancient Sea
A vast expanse of the Indian Ocean is a staggering 100 meters lower than the global average sea level because of a major dip in Earth’s gravity. Scientists now think they know the cause.....»»
Research team reports on discovery of grain-interior planar defects induced by heteroatom monolayer
In collaboration with the Institute of Physics at the Chinese Academy of Sciences (IPCAS), researchers from Beijing University of Technology (BJUT) have discovered a new type of grain-interior planar defect in a ceramic phase in TiC doped cemented tu.....»»
Our galaxy"s black hole not as sleepy as thought: astronomers
The supermassive black hole lurking at the center of our Milky Way galaxy is not as dormant as had been thought, a new study shows......»»
X-ray “light echoes” hint at outburst from Milky Way’s central black hole
The supermassive black hole at the center of our galaxy hasn't always been quiet. Enlarge / This is the first image of Sgr A*, the supermassive black hole at the center of our galaxy. It’s the first direct visual evidence of th.....»»
Heterostructure lets excitons carry more information for quantum applications
Excitons are electron-hole pairs in semiconductors that are electrostatically bound by strong Coulombic interactions. In ultrathin 2D semiconductors that are a few atoms thick (typically ~0.7 nm), the decreased z-dimension presents strong quantum con.....»»
Detection of an echo emitted by Sagittarius A* 200 years ago
An international team of scientists has discovered that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, emerged from a long period of dormancy some 200 years ago......»»
New study predicts the masses of the largest supermassive black holes in the universe
Near the center of the Milky Way Galaxy sits an immense object that astronomers call Sagittarius A*. This "supermassive" black hole may have grown in tandem with our galaxy, and it's not alone. Scientists suspect that similar behemoths lurk at the he.....»»
Directly imaging quantum states in two-dimensional materials
When some semiconductors absorb light, excitons (or particle pairs made of an electron bound to an electron hole) can form. Two-dimensional crystals of tungsten disulfide (WS2) have unique exciton states that are not found in other materials. However.....»»

Pulsars could help map the black hole at the center of the Milky Way
The theory of general relativity (GR), proposed by Einstein over a century ago, remains one of the most well-known scientific postulates of all time. This theory, which explains how spacetime curvature is altered in the presence of massive objects, r.....»»
Researchers use ultrasound to control orientation of small particles
Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape—for example, bacteria from other cells—for years, the ability to control their movement has remained.....»»
Researchers reveal mechanism of SnO2 electron transport layer modified by graphdiyne in perovskite solar cells
Prof. Sun Baoyun's group from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences recently used graphdiyne oxide (GDYO), fluorinated GDYO (FGDYO) and nitrogen-doped GDYO (NGDYO) to improve the SnO2 electron transport layer.....»»
