Phys.org / Laser pulses capture unexplored polaronic states
In an international experiment, researchers observed Jahn–Teller polarons—quasiparticles that could play an important role in future ultrafast spintronic devices. These polarons emerged within the crystal lattice of cobalt ...
Phys.org / Inorganic nanoscale device behaves like a single neuron, opening doors for AI and retinal implants
McGill University researchers have developed a light-detecting nanoscale structure that mimics how a neuron processes information. The neuron-like behavior emerges from the materials themselves, reducing the energy demand ...
Phys.org / Ancient asteroid barrage may explain why early Earth had no stable continents
New research led by Curtin University and QUT (Queensland University of Technology) has revealed that repeated asteroid impacts may have been the dominant force shaping early Earth, delivering vast amounts of heat into the ...
Phys.org / Plankton-linked vapors could speed cloud seed formation over cold oceans
For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it may be more important than ...
Phys.org / Scientists develop predictive roadmap to boost performance in next-gen spintronics
Chiral 2D metal halide perovskites (MHPs) are among the most promising materials for future technologies that exploit the spin of electrons in spin-based optoelectronics, or spintronics, but getting them to perform consistently ...
Phys.org / Natural hallucinogens may have evolved as ecological tools, not chemical accidents
Natural hallucinogens, such as psilocybin, mescaline, N,N-dimethyltryptamine (DMT) and related compounds, have generally received attention for their effects on human perception, emotion and cognition. Recently, interest ...
Phys.org / Ultra-precise technology can count damaged DNA fragments
The Korea Research Institute of Standards and Science has developed an ultrasensitive immunoassay-based analytical platform that can detect and quantify trace amounts of "Small Excised Damaged DNA (sedDNA)" fragments generated ...
Phys.org / Commute stress can fuel workplace conflict, but research suggests a simple fix
Pothole season, summer construction season or maybe bad weather. No matter the time of year, it's no surprise commuters who drive to work may start their day already feeling a bit on edge.
Phys.org / New insight into how cells move copper out of the mitochondrial matrix could guide novel treatments
Copper is essential for life. Our cells need the metal to make energy and stay healthy, but if it is in the wrong place or present in excess, copper can be deadly. Texas A&M AgriLife Research scientists have identified a ...
Phys.org / Fossils upend catastrophist narrative that flowering plants flourished only after dinosaur extinction
A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago.
Phys.org / Fossil fish tooth chemistry uncovers Southern Hemisphere role in Earth's ice age shift
To understand where Earth might be headed, it's important to know where it has been. Throughout its existence, especially over the past couple of million years, Earth has experienced periodic cold and warm intervals, known ...
Phys.org / Seven exotic quantum phases predicted in ultracold magnetic atoms, including topological superconductivity
Strongly interacting quantum particles are key to some of the most fascinating phenomena in modern physics—from magnetism and superconductivity to topological states. Yet the complexity of such systems makes many of their ...
