Electrons go with the flow
Oct 10, 2018 (SPX)
Hydrodynamic electron flow can only be observed in high-purity quantum materials. An international team of members from the IBM Research Laboratory Zurich, the ...
Journey to the Beginning of Time
Oct 09, 2018 (SPX)
Another option is to examine the oldest surviving stars from our own galaxy, the Milky Way, and use them to get a glimpse of what the conditions were like in th...
Observations challenge cosmological theories
Oct 05, 2018 (SPX)
For the next three years, the researchers will analyze their data in even greater detail. This will put them in a position to confirm whether the theories consi...
Single atoms break carbon's strongest bond
Oct 04, 2018 (SPX)
"We aimed to develop a technology that could degrade polyfluoroalkyl substances (PFAS), one of the most challenging pollutant remediation problems of the presen...
The faint glow of cosmic hydrogen
Oct 03, 2018 (SPX)
This detection reveals the existence of extensive masses of gas around primitive galaxies. The results of this study are based on observations made with the MUS...
New simulation sheds light on spiraling supermassive black holes
Oct 03, 2018 (SPX)
Just about every galaxy the size of our own Milky Way or larger contains a monster black hole at its center. Observations show galaxy mergers occur frequently i...
A universe aglow: lyman-alpha emission across the entire sky
Oct 02, 2018 (SPX)
An unexpected abundance of Lyman-alpha emission in the Hubble Ultra Deep Field (HUDF) region was discovered by an international team of astronomers using the MU...
No longer whistling in the dark: Scientists uncover source of perplexing waves
Sep 26, 2018 (SPX)
Now scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and other laboratories, using data from a NASA four-satellite...
How long does a quantum jump take?
Sep 25, 2018 (SPX)
In tiny fractions of a second, an electron of the material absorbs a photon, "jumps" into another state and leaves the surface. This "photoelectric effect" is s...
New observations to understand the phase transition in quantum chromodynamics
Sep 25, 2018 (SPX)
In the early universe, these particles moved (nearly) freely in a quark-gluon plasma. Then, in a phase transition, they combined and formed hadrons, among them ...
Searching for errors in the quantum world
Sep 21, 2018 (SPX)
Quantum mechanics can't describe the behaviour of planets, for instance, which remains the domain of the general theory of relativity. This theory, in turn, can...
Matter falling into a black hole at 30 percent of the speed of light
Sep 21, 2018 (SPX)
Black holes are objects with such strong gravitational fields that not even light travels quickly enough to escape their grasp, hence the description 'black'. T...
Wave-particle interactions allow collision-free energy transfer in space plasma
Sep 20, 2018 (SPX)
However, while the coexistence of waves with accelerated particles in the magnetosphere has been studied for many years, the gradual nature of the interactions ...
Looking back in time to watch for a different kind of black hole
Sep 20, 2018 (SPX)
The James Webb Space Telescope, scheduled for launch in 2021, might be able look far enough back into the early Universe to see a galaxy hosting a nascent massi...
Russian and German physicists developed a mathematical model of trapped atoms and ions
Sep 19, 2018 (SPX)
Atoms can be cooled down using a laser, but it's important to select proper frequency and direction. The same laser can create a so-called trap for cooled down ...
Princeton scientists discover a 'tuneable' novel quantum state of matter
Sep 13, 2018 (SPX)
An international team of researchers led by Princeton physicist Zahid Hasan has discovered a quantum state of matter that can be "tuned" at will - and it's 10 t...
Just seven photons can act like billions
Sep 11, 2018 (SPX)
Most substances physicists study are made up of huge numbers of particles - so large that there is essentially no difference between the behavioural properties ...
Black Hole Disks May Be Hiding in the Centers of Galaxies
Sep 10, 2018 (SPX)
Observations show that the centers of most galaxies harbor a supermassive black hole. The immense gravity of these objects acts to collect a dense population of...
Single molecule control for a millionth of a billionth of a second
Sep 10, 2018 (SPX)
Their new technique is the most sensitive way of controlling a chemical reaction on some of the smallest scales scientists can work - at the single molecule lev...
Algorithm accurately predicts how electromagnetic waves and magnetic materials interact
Sep 10, 2018 (SPX)
The tool allows engineers to design new classes of radio frequency-based components that are able to transport large amounts of data more rapidly, and with less...
