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.....»»
Engineering perovskite materials at the atomic level paves way for new lasers, LEDs
Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert electrical charge into lig.....»»
Assessment of damaged archaeological sites suggests they require individual protection concepts
An analysis of the damage to archaeological sites documented after a heavy rainfall event in July 2021 in parts of Germany shows that several factors increase the risk of damage to archaeological sites due to heavy rainfall and flooding events. For e.....»»
World"s highest-voltage gun accelerates electrons from zero to 80% the speed of light
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed and tested the world's highest voltage polarized electron gun, a key piece of technology needed for building the world's first fully polarized Electron-I.....»»
Underwater caves yield clues that may help explain early expansion of Homo sapiens into Mediterranean islands
Archaeological surveys led by scientists at Washington University in St. Louis suggest that coastal and underwater cave sites in southern Sicily contain important new clues about the path and fate of early human migrants to the island......»»
Review of English-language textbooks from 34 countries reveals persistent pattern of stereotypical gender roles
Gender biases around male and female roles and under-representation of female characters appeared in textbooks from around the world, with male-coded words appearing twice as often as female-coded words on average, according to a study published Octo.....»»
Can visiting genocide memorials make you more empathic?
Each year, people visit museums and memorial sites as part of educational interventions organized around the remembrance of a genocide or an atrocity. Many schools visit a concentration camp as part of Holocaust education, such as Auschwitz-Birkenau......»»
Injured comb jellies can fuse into a single organism
Ctenophores merge with neighbors at wound sites, making animals with duplicate parts. Comb jellies, technically known as ctenophores, are one of the weirdest creatures on Earth. T.....»»
"Invisibility" and quantum computing tipped for physics Nobel
An "invisibility cloak", an atomic force microscope or quantum computing are some of the scientific achievements that could win a Nobel prize in physics Tuesday......»»

Geological surveys shed light on the formation mystery of Uruguay"s amethyst geodes
Amethyst is a violet variety of quartz that has been used as a gemstone for many centuries and is a key economic resource in northern Uruguay. Geodes are hollow rock formations often with quartz crystals, such as amethyst, inside......»»
Chemist challenges traditional views on crystal growth
Remember that old high school chemistry experiment where salt crystals precipitate out of a saltwater solution—or maybe the one where rock candy crystals form from sugar water? It turns out that your understanding of how crystals formed in those so.....»»
The Gut Might Hold the Key to Treating Long Covid in Kids
A placebo-controlled study aims to test if treating gut issues can help children struggling with persistent Covid symptoms......»»
Beyond "one pore at a time": New method of generating multiple, tunable nanopores
Nanoporous membranes with atomic-scale holes smaller than one-billionth of a meter have powerful potential for decontaminating polluted water, pulling valuable metal ions from the water, or for osmotic power generators......»»
Seeing double: Designing drugs that target "twin" cancer proteins
Some proteins in the human body are easy to block with a drug; they have an obvious spot in their structure where a drug can fit, like a key in a lock. But other proteins are more difficult to target, with no clear drug-binding sites......»»
In storms like Hurricane Helene, flooded industrial sites and toxic chemical releases are a silent and growing threat
Hundreds of industrial facilities with toxic pollutants were in Hurricane Helene's path as the powerful storm flooded communities across the Southeast in late September 2024......»»
A new apparatus for analyzing partial coherence in integrated photonic networks
Anyone familiar with optics labs is familiar with the extremes of light coherence: laser beams are highly coherent, producing clear interference patterns used for precise applications like atomic manipulation or precise sensing. In contrast, light fr.....»»
Breathing may introduce microplastics to the brain—new study
Small plastic particles are everywhere: in the soil where our food is grown, in the water we drink and in the air we breathe. They got there from the plastic we throw away, which ends up in landfill sites, rivers and seas. There the plastic waste slo.....»»
Research team succeeds in ultra-fast switching of tiny light sources
Extremely thin materials consisting of just a few atomic layers promise applications for electronics and quantum technologies. An international team led by TU Dresden has now made remarkable progress with an experiment conducted at Helmholtz-Zentrum.....»»
Discovering new energy levels in atomic hyperfine structures
Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the development of Fourier transform spectroscopy, and t.....»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
