New measure of gravitational constant higher than expected
Maxwell's demon can use quantum information to generate work
May the force be with us? Precise measurements test quantum electrodynamics, constrain possible fifth fundamental force
Model-independent measurement of dark matter mass could lead to future discoveries
Quark asymmetries hint at physics beyond the Standard Model
Unexpected energy barrier for uptake of hydrogen in tungsten wall of fusion reactor
The reactor walls of future fusion reactors will absorb fusion fuel one million times slower than previous research had indicated. A layer of bound hydrogen on the surface of the tungsten wall seems to protect ...
New map of Universe may reconcile conflicting cosmological observations
Physicists find way to boot up quantum computers 72 times faster than previously possible
Press the start button, switch on the monitor, grab a cup of coffee and off you go. That is pretty much how most us experience booting up a computer. But with a quantum computer the situation is very different. ...
Physics duo discover 13 new solutions to Newtonian three-body orbit problem
IceCube Neutrino Observatory reports first evidence for extraterrestrial high-energy neutrinos
(Phys.org) —A massive telescope in the Antarctic ice reports the detection of 28 extremely high-energy neutrinos that might have their origin in cosmic sources. Two of these reached energies greater than ...
Physicists use dysprosium to put bounds on maximum speed of electrons
Albert Einstein's assertion that there's an ultimate speed limit – the speed of light – has withstood countless tests over the past 100 years, but that didn't stop University of California, Berkeley, postdoc Michael Hohensee ...
Tests confirm nickel-78 is a 'doubly magic' isotope
The stability of atoms can vary considerably from one element to the next, and also between isotopes of the same element (whose nuclei contain the same number of protons but different numbers of neutrons). ...
Time reversal findings may open doors to the future
(Phys.org)—Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field ...
