Scientists perform world's smallest MRI on single atoms
Jul 01, 2019 (UPI)
Magnetic resonance imaging measures the density of atomic spins, the electromagnetic properties of electrons and protons, inside the human body. Most MRI scans ...
Building a bridge to the quantum world
Jul 01, 2019 (SPX)
Entanglement is a phenomenon typical of the quantum world, which is not present in the so-called classical world - the world and laws of physics that govern our...
The observation of topologically protected magnetic quasiparticles
Jul 01, 2019 (SPX)
The conceptual discovery of a topological insulator generates attention from a fundamental and technological aspect. The study showed that we can expect a non-d...
Astronomers Discover Eight Buried Dual AGN Candidates
Jun 28, 2019 (SPX)
This result will be presented by graduate student Ryan Pfeifle of George Mason University (Fairfax, Virginia, USA) at the annual meeting of the European Astrono...
New model explains appearance of supermassive black holes in early universe
Jun 28, 2019 (UPI)
According to the new study, published this week in the Astrophysical Journal Letters, supermassive black holes grow extremely fast over a very short amount of t...
The first AI universe sim is fast and accurate - and its creators don't know how it works
Jun 28, 2019 (SPX)
"We can run these simulations in a few milliseconds, while other 'fast' simulations take a couple of minutes," says study co-author Shirley Ho, a group leader a...
Scientists capture atomic motion in four dimensions for the first time
Jun 27, 2019 (UPI)
Nucleation is the coalescence of atoms and molecules that happens as matter changes states -- during freezing, melting or evaporation. Using a new high-tech ima...
MUSE Reveals a Glowing Ring of Light in the Distant Universe
Jun 27, 2019 (SPX)
This result will be presented by Adelaide Claeyssens (Centre de Recherche Astrophysique de Lyon) at the annual meeting of the European Astronomical Society (EWA...
Electron-behaving nanoparticles rock current understanding of matter
Jun 24, 2019 (SPX)
"We have never seen anything like this before," said Northwestern's Monica Olvera de la Cruz, who made the initial observation through computational work. "In o...
What is an atomic clock?
Jun 21, 2019 (JPL)
Ultimately, this new technology could make spacecraft navigation to distant locations like Mars more autonomous. But what is an atomic clock? How are they used ...
How an Atomic Clock Will Get Humans to Mars on Time
Jun 17, 2019 (JPL)
Navigators today tell a spacecraft where to go by calculating its position from Earth and sending the location data to space in a two-way relay system that can ...
Planck Finds No New Evidence for Cosmic Anomalies
Jun 10, 2019 (ESA)
Planck's latest results come from an analysis of the polarisation of the Cosmic Microwave Background (CMB) radiation - the most ancient light in cosmic history,...
Detection of powerful winds driven by a supermassive black hole
Jun 10, 2019 (SPX)
The effect that this activity has on the host galaxy is known as AGN feedback, and one of its properties are galactic winds: this is gas from the centre of the ...
'Best ever' simulation solves 40-year black hole mystery
Jun 06, 2019 (AFP)
Coming fresh on the heels of the first ever photo of one of the giant objects, which are scattered across the Universe, astrophysicists are now several steps cl...
Most-detailed-ever simulations of black hole solve longstanding mystery
Jun 06, 2019 (SPX)
The research will publish on June 5 in the Monthly Notices of the Royal Astronomical Society. Among the findings, the team of computational astrophysicists from...
Five Things to Know about NASA's Deep Space Atomic Clock
Jun 06, 2019 (JPL)
Built by NASA's Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a technology demonstration that will help spacecraft navigate ...
Cool, Nebulous Ring Around Milky Way's Supermassive Black Hole
Jun 06, 2019 (SPX)
We now know that this region is brimming with roving stars, interstellar dust clouds, and a large reservoir of both phenomenally hot and comparatively colder ga...
Physicists create stable, strongly magnetized plasma jet in laboratory
Jun 04, 2019 (SPX)
Now, a team of scientists led by physicists Lan Gao of the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Edison Liang of Rice...
The geometry of an electron determined for the first time
Jun 03, 2019 (SPX)
This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published ...
Colliding lasers double the energy of proton beams
May 28, 2019 (SPX)
Proton therapy involves firing a beam of accelerated protons at cancerous tumours, killing them through irradiation. But the equipment needed is so large and ex...
