Physicists aim to catch slow-decaying dark particle inside LHC
Apr 18, 2019 (UPI)
Dark matter is apparently everywhere, binding galaxies together. But astronomers can only intimate dark matter's presence by measuring its gravitational effect ...
Lithium in ancient star gives new clues for big bang nucleosynthesis
Apr 18, 2019 (SPX)
The study of the most ancient stars in the Milky Way allows us to infer the early properties of the galaxy, its chemical composition, and its assembly history. ...
Peeling back the darkness of M87
Apr 17, 2019 (SPX)
A luminous orange circle with a dark center and a bright lip, the image is a product of the Event Horizon Telescope (EHT), a distributed collection of eight, hi...
Travel through wormholes is possible, but slow
Apr 16, 2019 (SPX)
But don't pack your bags for a trip to other side of the galaxy yet; although it's theoretically possible, it's not useful for humans to travel through, said th...
The discrete-time physics hiding inside our continuous-time world
Apr 16, 2019 (SPX)
However, invariably a scientist can only observe the state of a system at discrete times, separated by some gap, rather than continually. For example, a stock m...
New Super-Accurate Optical Atomic Clocks Pass Critical Test
Apr 12, 2019 (SPX)
"A more accurate definition of a second and a better time-keeping infrastructure would support continuing advances in the timing systems used in a wide range of...
Astronomers capture first image of a black hole
Apr 10, 2019 (SPX)
"We are giving humanity its first view of a black hole - a one-way door out of our universe," said EHT project director Sheperd S. Doeleman of the Center for As...
Journey to the Big Bang via Lithium of a Milky Way Star
Apr 08, 2019 (SPX)
In astrophysics, any element heavier than hydrogen and helium is termed "metal" and lithium is among the lightest of these metals. Researchers at the IAC and th...
'Featherweight oxygen' discovery opens window on nuclear symmetry
Apr 03, 2019 (SPX)
Oxygen is one of the most abundant elements in the solar system, but oxygen-11 can be produced only in a laboratory. It decays immediately after its creation by...
Behavior of 'trapped' electrons in a one-dimensional world observed in the lab
Apr 02, 2019 (SPX)
The Tomonaga-Luttinger liquid theory predicted this decades ago. In the lab, however, this phenomenon has so far only been shown indirectly. An international re...
Low-loss, all-fiber system for strong and efficient coupling between distant atoms
Apr 02, 2019 (SPX)
"This kind of system may enable quantum computation, free from the limited computational power that systems today experience, and quantum networks that transfer...
Syracuse University physicist discovers new class of pentaquarks
Mar 28, 2019 (SPX)
Assisted by Liming Zhang, an associate professor at Tsinghua University in Beijing, Skwarnicki has analyzed data from the Large Hadron Collider beauty (LHCb) ex...
What Happened Before the Big Bang
Mar 27, 2019 (SPX)
Although cosmic inflation is well known for resolving some important mysteries about the structure and evolution of the universe, other very different theories ...
Searching for disappeared anti-matter
Mar 27, 2019 (SPX)
In the Belle II experiment, electrons and their anti-particles, the positrons, are brought to collision. This results in the generation of B mesons, couples con...
Listening to the quantum vacuum
Mar 27, 2019 (SPX)
Louisiana State University Department of Physics and Astronomy Associate Professor Thomas Corbitt and his team of researchers now present the first broadband, o...
It's spring already? Physics explains why time flies as we age
Mar 21, 2019 (SPX)
According to Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke, this apparent temporal discrepancy can be blamed on the ever-slowing spee...
Researchers reverse the flow of time on IBM's quantum computer
Mar 21, 2019 (SPX)
Or can we? An international team of scientists led by the U.S. Department of Energy's (DOE) Argonne National Laboratory explored this question in a first-of-its...
Exotic 'second sound' phenomenon observed in pencil lead
Mar 21, 2019 (SPX)
We know heat doesn't behave this way in our day-to-day surroundings. But now MIT researchers have observed this seemingly implausible mode of heat transport, kn...
UK industry to help answer fundamental questions about universe
Mar 19, 2019 (SPX)
The new PIP-II particle accelerator at the Fermi National Accelerator Laboratory (Fermilab) will power the Deep Underground Neutrino Experiment, which aims to a...
Astronomers discover 83 supermassive black holes in early universe
Mar 14, 2019 (SPX)
Supermassive black holes are found at the centers of galaxies, and have masses millions or even billions of times that of the Sun. While they are prevalent in t...
