Persistent swinging of electrons between atomic sites in crystals
This crystal lattice consists of a large number of unit cells with an identical atomic arrangement. In the elementary adiabatic picture, the motions of electrons in the crystal follow the motion of the atomic nuclei instantly, i.e., atomic nuclei and.....»»
Have we found all the major Maya cities? Not even close, new research suggests
Archaeologists have analyzed lidar data from a completely unstudied corner of the Maya world in Campeche, Mexico, revealing 6,674 undiscovered Maya structures, including pyramids like those at the famous sites of Chichén Itzá or Tikal......»»
For heating plasma in fusion devices, researchers unravel how electrons respond to neutral beam injection
Heating a plasma for fusion research requires megawatts of power. One approach that research tokamaks use to achieve the necessary power input is neutral beam injection (NBI). With NBI, fast neutral particles are generated in a device called a beam s.....»»
VAMMIT trials: Tackling methane emissions in mining
New CSIRO technology that destroys methane at mine sites is showing great promise—and attracting great interest from industry and governments worldwide......»»
Molecular insights into the dynamic dance of nanoplastics and natural organic matter
Nanoplastics, emerging as persistent environmental pollutants, pose significant threats due to their durability and wide distribution in water bodies. Their interactions with natural organic matter are critical, influencing pollutant retention, micro.....»»
X-ray spectroscopy study maps ultrafast charge delocalization in aqueous environments
The movement of electron density is a subject of interest for chemists worldwide, as substances interact through electrons. These processes are ultrafast and traditionally require time-resolved experiments at the attosecond level to study and describ.....»»
Specially designed transistors allow researchers to "hear" defects in a promising nanomaterial
An international research team led by NYU Tandon School of Engineering and KAIST (Korea Advanced Institute of Science and Technology) has pioneered a new technique to identify and characterize atomic-scale defects in hexagonal boron nitride (hBN), a.....»»
Researchers synthesize carbon nanotubes with precise chirality
Researchers have achieved a significant breakthrough in the synthesis of carbon nanotubes (CNTs) by developing a novel catalyst that allows for precise control over their atomic arrangement, known as chirality. This advancement paves the way for the.....»»
Combining satellite methods provides drought detection from space
Observing sites like the Amazon basin from space has underscored the capability of satellites to better detect signs of drought, according to a new study......»»
Scientists create new overwintering sites for monarch butterflies on a warming planet
The migration of the monarch butterfly is one of the wonders of the natural world. Each autumn, a new generation of monarch butterflies is born in the northern United States and southern Canada. Hundreds of millions of these butterflies then fly to t.....»»
New technique enhances precision in measuring short-lived atomic nuclei
Researchers at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) have introduced a technique, Tune-IMS, designed to improve the precision of isochronous mass spectrometry (IMS) in measuring short-lived atomic nuclei. The development offers refin.....»»
Deep learning illuminates past and future atmospheric blocking events
Atmospheric blocking events are persistent, high-impact weather patterns that occur when large-scale high-pressure systems become stationary and divert the jet stream and storm tracks for days to weeks, and can be associated with record-breaking floo.....»»
Leap Seconds May Be Abandoned by the World’s Timekeepers
We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?.....»»
The neutron lifetime problem—and its possible solution
Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes.....»»
Multicolor persistent luminescent materials for dynamic optical anti-counterfeiting
Optical anti-counterfeiting technology, as a preventive measure, has deeply permeated our daily lives. Visually readable codes designed based on optical materials are widely used due to their ease of verification, reasonable cost, and difficulty in r.....»»
First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
Dual-species atomic arrays show promise for quantum error correction
A study in Nature Physics has realized a dual-species Rydberg array combining rubidium (Rb) and cesium (Cs) atoms to enhance quantum computing and its applications......»»
New technologies could help destroy persistent "forever chemicals"
Scientists and engineers are developing new ways to destroy per- and poly-fluoroalkyl substances (PFAS) efficiently and sustainably. This class of chemicals is known as "forever chemicals" because PFAS persist and accumulate in the environment, anima.....»»
"Killer electrons": Lightning storms play cosmic pinball with space weather
When lightning strikes, the electrons come pouring down. In a new study, researchers at the University of Colorado Boulder, led by an undergraduate student, have discovered a novel connection between weather on Earth and space weather. The team utili.....»»
Interdisciplinary advances in microcombs: Bridging physics and information technology
Researchers are excited about the potential of microcombs, miniature devices that generate precise time and frequency standards. These microcombs could revolutionize fields from high-speed communication, high-resolution measurements to precise atomic.....»»
Research shows dating apps, sites are leading to more diverse couples
The so-called "traditional" way of dating has changed drastically over time, especially in the last decade. While most couples used to meet through families and friends or local organizations like church, according to University of New Mexico Sociolo.....»»
