Understanding how quantum gravity affects low-energy physics
Researchers have, for the first time, identified the sufficient and necessary conditions that the low-energy limit of quantum gravity theories must satisfy to preserve the … Read more
Astrophysical shock phenomena reproduced in the laboratory
Vast interstellar events where clouds of charged matter hurtle into each other and spew out high-energy particles have now been reproduced in the lab with … Read more
Antineutrino detection could help remotely monitor nuclear reactors
Technology to measure the flow of subatomic particles known as antineutrinos from nuclear reactors could allow continuous remote monitoring designed to detect fueling changes that … Read more
Quantum entanglement in chemical reactions? Now there’s a way to find out
Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don’t know for sure … Read more
Einstein was right about relativity, UCLA says — for now
More than 100 years after Albert Einstein published his iconic general theory of relativity, it is beginning to fray at the edges, said Andrea Ghez, … Read more
Physicists count sound particles with quantum microphone
Stanford physicists have developed a “quantum microphone” so sensitive that it can measure individual particles of sound, called phonons. The device, which is detailed July … Read more
Scientists film molecular rotation
Scientists have used precisely tuned pulses of laser light to film the ultrafast rotation of a molecule. The resulting “molecular movie” tracks one and a … Read more
Seeking new physics, scientists borrow from social networks
When two protons collide, they release pyrotechnic jets of particles, the details of which can tell scientists something about the nature of physics and the … Read more
Army project may advance quantum materials, efficient communication networks
A U.S. Army project exploring novel applications of superconducting resonators has discovered these systems may be used to simulate quantum materials impossible to otherwise fabricate. … Read more
How random tweaks in timing can lead to new game theory strategies
Most game theory models don’t reflect the relentlessly random timing of the real world. In some models, players may receive information at the same time, … Read more
