Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
Were Bohr and von Neumann really in conflict over quantum measurements?
Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar views than previously thought regarding the nature of quantum systems, and the classical apparatus used to measure them......»»
What the jet stream and climate change had to do with the hottest summer on record
Summer 2024 was officially the Northern Hemisphere's hottest on record. In the United States, fierce heat waves seemed to hit somewhere almost every day......»»
ISPs tell Supreme Court they don’t want to disconnect users accused of piracy
ISPs say Sony's win over Cox would force them to do "mass Internet evictions." Enlarge / The Supreme Court of the United States in Washington, DC, in May 2023. (credit: Getty Images | NurPhoto) Four more large Internet s.....»»
LHC experiments observe quantum entanglement at the highest energy yet
Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bend.....»»
Quantum ‘Ghost Imaging’ Reveals the Dark Side of Plants
Entanglement lets researchers watch plants in action without disruptive visible light.....»»
See the first images from Europe’s Sentinel-2C satellite looking down on Earth
Earlier this month, the European Space Agency (ESA) launched its newest Earth-observation satellite, known as Copernicus Sentinel-2C......»»

Pollen affects cloud formation and precipitation patterns, researchers find
Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and minus 25 degrees Celsius......»»
Why holding kids back fails, and what to do about it
For decades, schools have allowed children to advance to the next grade even when they're not reading at grade level. But more and more states are adopting policies to hold students back if they fail standardized tests in reading......»»
People underestimate the income of the top 1%, researchers find
People selectively underestimate how rich the world's richest people are, according to a study. Increasing income inequality in many countries is driven by steep gains among the top 1% of earners. In the United States, support for policies that would.....»»
Research team uses terahertz pulses of light to shed light on superconducting disorder
A team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg, Germany, and Brookhaven National Laboratory in the United States has demonstrated a new way to study disorder in superconductors using ter.....»»
Tunable nonlinear Hall effect observed at room temperature in tellurium
A research team has discovered significant nonlinear Hall and wireless rectification effects at room temperature in elemental semiconductor tellurium (Te). Their research is published in Nature Communications......»»
Researchers explore the effects of the Black Lives Matter protests on racial bias
The murder of George Floyd in 2020 revived the Black Lives Matter movement, a large scale social movement that aims to highlight and reduce structural racism and inequality in the United States. The movement—and its coverage—strongly affected how.....»»

Energy transmission in quantum field theory requires information: Research finds surprisingly simple relationship
An international team of researchers has found a surprisingly simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. Their work was published in Physical Review Letters.....»»
Making "atomic lasagna": New method transforms 3D materials into stable layered thin films with promising properties
A research team discovered a method to transform materials with three-dimensional atomic structures into nearly two-dimensional structures—a promising advancement in controlling their properties for chemical, quantum, and semiconducting application.....»»

African countries are adopting two houses of parliament to boost democracy. But that"s not always what happens
At independence, most African states had two legislative chambers—a lower and upper chamber—in their parliament. African leaders saw that as a colonial legacy and as inefficient, so most states removed the upper chambers. Before 1990, only two st.....»»
