Teenage Maurice Sendak illustrated his teacher’s 1947 pop-sci book
Drawings of Atomics for the Millions "reveal early postwar anxieties about nuclear war." Enlarge / A young Maurice Sendak’s illustration of two possible outcomes of atomic power for the 1947 pop-sci book Atomics for the Million.....»»
Record-breaking drought in southern China linked to Eurasian warming and tropical sea surface temperature
Southern China experienced an extreme drought that persisted from summer to autumn in 2022, ranking as the most severe drought since 1980. The reason for the occurrence of this extreme drought event was investigated. It shows that both the Eurasian w.....»»
Controlling molecular electronics with rigid, ladder-like molecules
As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years, according to Moore's law. Molecular elec.....»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
Superconductivity study confirms existence of edge supercurrents
Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must.....»»
Nontoxic ceramic could replace lead-based electronic components
The ceramic produced in Prof. Igor Lubomirsky's lab at the Weizmann Institute of Science seemed too good to be true. It belongs to a class of materials that are the backbone of many essential technologies but that unfortunately also create an environ.....»»
New varactor enhances quantum dot device measurements at millikelvin temperatures
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequenc.....»»
Breaking down the indestructible: New technologies target PFAS environmental menace
PFAS are synthetic chemicals widely used in products such as non-stick cookware and waterproof clothing due to their water and grease-resistant properties. However, their persistence in the environment has led to widespread contamination and signific.....»»
Exploring bamboo charcoal"s slow-release properties for enhanced anti-acne formulations containing bamboo vinegar
Bamboo vinegar is a concentrated liquid obtained from bamboo under high temperature and anaerobic conditions. It contains more than 200 organic components, including organic acids, phenols, ketones, alcohols, and esters, among which acetic acid is th.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Researchers demonstrate metasurfaces that control thermal radiation in unprecedented ways
Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control the optical properties of t.....»»
World"s first micromachine twists 2D materials at will
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbe.....»»
Physicists observe key minuscule molecular interactions in ultra-fast atomic processes
An international team of scientists is the first to report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays......»»
Astronomers think they’ve found a plausible explanation of the Wow! signal
Magnetars could zap clouds of atomic hydrogen, producing focused microwave beams. Enlarge / The Wow! signal, represented as "6EQUJ5," was discovered in 1977 by astronomer Jerry Ehman. (credit: Public domain) An unusually.....»»
Ancient microbes linked to evolution of human immune proteins
When you become infected with a virus, some of the first weapons your body deploys to fight it are those passed down to us from our microbial ancestors billions of years ago. According to new research from The University of Texas at Austin, two key e.....»»
New supramolecular polymer shows spontaneous unfolding and aggregation
In polymers, the competition between the folding and aggregation of chains, both at an individual level and between chains, can determine the mechanical, thermal, and conductive properties of such materials. Understanding the interplay of folding and.....»»
Astronomers explore the properties of quasar 1604+159
Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the properties of this quasar, in.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
