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.....»»
Scientists enhance Seaglider technology to measure carbon dioxide
Scientists around the world rely on ocean monitoring tools to measure the effects of climate change. Researchers at the University of Alaska Fairbanks and their industry partners have advanced the technology available to measure carbon dioxide in the.....»»
Axion dark matter may make spacetime ring
Dark matter made out of axions may have the power to make space-time ring like a bell, but only if it is able to steal energy from black holes, according to new research......»»
Astronomers measure cosmic electrons at the highest energies to date
Five telescopes of the H.E.S.S.-collaboration in Namibia are used to study cosmic radiation, especially gamma radiation. With data from 10 years of observations, researchers have now been able to detect cosmic electrons and positrons with an unpreced.....»»
Satellite data and algorithms reveal which ships emit excessive nitrogen
Ships are still emitting too much nitrogen oxide. Until now, it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. K.....»»
Growing soybeans has a surprisingly significant emissions footprint, but it"s ripe for reduction
Over the typical two-year rotation of corn and soybeans most Iowa farmers use, 40% of nitrous oxide emissions are in the soybean year, according to a new study by an Iowa State University research team......»»
Automated 3D computer vision model offers a new tool to measure and understand dairy cow behavior and welfare
Dairy cows typically rest for 10 or more hours a day, so a dry, clean, and comfortable place—such as a freestall—to lie down and rest is essential for their health, well-being, and production performance. One key factor in whether stalls are comf.....»»
A new method for creating a quantum gas
Cooling atomic gases to the quantum regime often involves time-consuming steps. Electromagnetically induced transparency now achieves quantum degeneracy with high efficiency......»»
Neat, precise and brighter than ever: New technologies improve temporal coherence of XFEL pulses
X-ray free-electron lasers produce pulses of light that are exceptionally bright, making them powerful tools for studying ultrafast chemical reactions, biological processes, or probing the structure of materials at atomic scales......»»
Electron imaging reveals the vibrant colors of the outermost electron layer
Surfaces play a key role in numerous chemical reactions, including catalysis and corrosion. Understanding the atomic structure of the surface of a functional material is essential for both engineers and chemists. Researchers at Nagoya University in J.....»»
Invisible touch: Researchers give AI the ability to feel and measure surfaces
AI-based technologies are rapidly learning to see, converse, calculate and create. One thing they still don't do well, however, is measure or "feel" surfaces—a purely mechanical function......»»
The brain-computer interface revolution is just getting started
Brain-Computer Interfaces fascinate the sci-fi and medical communities in equal measure, here's how close the transformative technology is to everyday use......»»
Scientists gain new insights into how mass is distributed in hadrons
Scientists can determine the mass of subatomic particles that are built from quarks by looking at the particles' energy and momentum in four-dimensional spacetime. One of the quantities that encode this information, called the trace anomaly, is linke.....»»
ATLAS observes top quarks in lead–lead collisions
At a talk held at CERN this week, the ATLAS collaboration at the Large Hadron Collider (LHC) reported observing top quarks in collisions between lead ions, marking the first observation of this process in interactions between atomic nuclei......»»
Wearable tech for space station research
Many of us wear devices that count our steps, measure our heart rate, track sleep patterns, and more. This information can help us make healthy decisions—research shows the devices encourage people to move more, for example—and could flag possibl.....»»
Researchers advocate for new framework to measure sustainable economic growth
The global economy is in transition, with energy systems moving from a central reliance on fossil fuels. In addition, the COVID-19 pandemic reshaped consumer behavior, labor markets, and business practices, and geopolitics and war have disrupted long.....»»
53 years of survey data confirm African elephant decline
Habitat loss and poaching have driven dramatic declines in African elephants, but it is challenging to measure their numbers and monitor changes across the entire continent. A new study has analyzed 53 years of population survey data and found large-.....»»
iPhones on iOS 18.1 will automatically reboot and lock down after being idle for a while
A hidden feature in iOS 18.1 will automatically reboot a locked iPhone when it is asleep but hasn't been unlocked for a while, presumably as a security measure.The feature has been identified as an "inactivity reboot," and is similar to a feature fou.....»»
Kagome superconductor breaks the rules at record-breaking temperatures
Using muon spin rotation at the Swiss Muon Source SmS, researchers at the Paul Scherrer Institute (PSI) have discovered that a quantum phenomenon known as time-reversal symmetry breaking occurs at the surface of the Kagome superconductor RbV3Sb5 at t.....»»
