Using atomic excitations to measure the rotation of spacetime
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth's surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absor.....»»
Improved AI process could better predict water supplies
A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and o.....»»
Generating graph states of atomic ensembles via photon-mediated entanglement
Graph states, a class of entangled quantum states that can be represented by graphs, have been the topic of numerous recent physics studies, due to their intriguing properties. These unique properties could make them particularly promising for quantu.....»»
Mapping the Milky Way"s magnetic field in 3D
We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of.....»»
Scientists say voluntary corporate emissions targets not enough to create real climate action
Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper......»»
Scientists tune the entanglement structure in an array of qubits
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain the macroscopic behavior.....»»
How studying trends in human lifespans can measure progress in addressing inequality
People are living longer lives compared to previous generations but, over the last few decades, there has been a hidden shift—they are passing away at increasingly similar ages......»»
Manipulating the geometry of the "electron universe" in magnets
Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the "electron universe," which describes the structure of electronic quantum states in a manner math.....»»
TikTok fears point to larger problem: Poor media literacy in the social media age
The U.S. government moved closer to banning the video social media app TikTok after the House of Representatives attached the measure to an emergency spending bill on Apr. 17, 2024. The House voted on each of the four components of the bill, and the.....»»
Magnetic with a pinch of hydrogen: Research team develops new idea to improve the properties of ultra-thin materials
Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the.....»»
House passes bill saying ByteDance must sell or spin off TikTok or face a ban
The US House of Representatives has passed a combination bill related to sanctions on other countries, such as Russia that includes language that could force the sale or divestiture of TikTok.Legislators have framed the measure in such a way as to do.....»»
Estimating uncertainty in atomic spectroscopy
If you repeat a measurement with the same or different instruments, you'll get slightly different numbers each time. Estimating the uncertainties associated with these numbers turns them into an informative result......»»
Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery
Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in everyday life, it represents.....»»
Study finds iron-rich enamel protects, but doesn"t color, rodents" orange-brown incisors
Chattering squirrels, charming coypus, and tail-slapping beavers—along with some other rodents—have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano, providing an atomic-level view of the.....»»
Scientists develop framework to measure plastic emissions and bolster U.N. efforts to reduce pollution
University of Toronto (U of T) scientists have developed a framework for measuring plastic pollution emissions akin to the global standard for measuring greenhouse gas emissions. The researchers say the approach will boost identification of the bigge.....»»
Future Apple Vision Pro could help the user get life-saving medical advice
Apple is developing technology for wearable devices like Apple Vision Pro that measure and monitor biometric data and location to provide tailored and potentially lifesaving advice.Apple wearables could provide medication reminders and guidance. An A.....»»
Traces of DNA in the stomachs of predatory snails provide new insights into the ecology of placozoans
Placozoans are among the simplest animals and occur worldwide in coastal waters. It was previously assumed that the tiny creatures, which measure just a few millimeters, live either on hard surfaces—such as rocks, corals, and mangrove roots—or fl.....»»
Examining the blowtorch effect of satellite reentry through video
A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgar.....»»
Team is first ever to measure qubits with ultrasensitive thermal detectors, evading Heisenberg uncertainty principle
Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering......»»
New technique lets scientists create resistance-free electron channels
An international research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state—an exotic quantum phenomenon that could help res.....»»
Computing how quantum states overlap
Quantum many-body systems are things such as atomic nuclei that consist of many tiny particles moving in complex ways. This makes it extremely difficult to predict how the systems behave as the particles interact. To study these systems, researchers.....»»
