Physicist identifies how electron crystals melt
The mysterious changes in phases of matter—from solid to liquid and back again—have fascinated Eun-Ah Kim since she was in lower elementary school in South Korea. Without cold drinking water readily available, on hot days the children would bring.....»»
The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal
In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction......»»
Research identifies mechanism behind drug resistance in malaria parasite
Collaborating researchers have discovered a link between malaria parasites' ability to develop resistance to antimalarial drugs—specifically artemisinin (ART)—through a cellular process called transfer ribonucleic acid (tRNA) modification. tRNA m.....»»
Electron vortices in graphene detected for the first time
When an ordinary electrical conductor—such as a metal wire—is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery. While moving, electrons frequently collide with impurity atoms or v.....»»

Cloudflare announced Cloudflare for Unified Risk Posture, a new suite of risk management solutions designed to streamline the process of identifying, evaluating, and managing cyber threats that pose risk to an organization, across all environments. P.....»»
Study identifies early warning signals for the end of the African humid period
The transition from the African humid period (AHP) to dry conditions in North Africa is the clearest example of climate tipping points in recent geological history. They occur when small perturbations trigger a large, non-linear response in the syste.....»»
Fruit fly model identifies key regulators behind organ development
A new computational model simulating fruit fly wing development has enabled researchers to identify previously hidden mechanisms behind organ generation......»»
Two facilities team up for structural biology advances with X-ray free-electron lasers and exascale computing
Plans to unite the capabilities of two cutting-edge technological facilities promise to usher in a new era of dynamic structural biology. Through DOE's Integrated Research Infrastructure, or IRI, initiative, the facilities will complement each other'.....»»
Attosecond core-level spectroscopy reveals real-time molecular dynamics
Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxati.....»»
Collaboration identifies rare nuclear decay in long-lived potassium isotope
Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10%.....»»
When injecting pure spin into chiral materials, direction matters
Researchers from North Carolina State University and the University of Pittsburgh studied how the spin information of an electron, called a pure spin current, moves through chiral materials. They found that the direction in which the spins are inject.....»»
