Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»
Self-dealing has a long history on crypto exchanges: Researchers investigate "wash trading"
In 2019, the American tech trading company Bitwise presented to the SEC that an astounding 95% of cryptocurrency exchanges were fake. This claim may be credited to a type of market manipulation called "wash trading," which involves inflating trading.....»»

Using long-term monitoring data from 46 German lakes, researchers from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in cooperation with the Helmholtz Center for Environmental Research in Magdeburg have shown that surface tem.....»»
Team develops method for control over single-molecule photoswitching
Scientists from the Department of Physical Chemistry at the Fritz Haber Institute have made an innovative discovery in nanoscale optoelectronics. The study, published in the journal Nature Communications and titled "Atomic-Precision Control of Plasmo.....»»
Quantum breakthrough achieved in the coolest place on the space station
The Cold Atom Lab on the International Space Station has made use of atom interferometry in space to detect environmental changes......»»
"Mirror" nuclei help connect nuclear theory and neutron stars
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these.....»»
AI, computation, and the folds of life: Supercomputers help train a software tool for the protein modeling community
Form follows function, and this is especially true for life's building blocks—proteins. The folds and shape of molecular proteins reveal their function in supporting life......»»
NASA demonstrates "ultra-cool" quantum sensor for first time in space
NASA's Cold Atom Lab, a first-of-its-kind facility aboard the International Space Station, has taken another step toward revolutionizing how quantum science can be used in space. Members of the science team measured subtle vibrations of the space sta.....»»
Rapid removal of emerging endocrine disruptors in wastewater using high-performance single-atom catalysts
Bisphenols are widely used as the main raw material for plastics such as receipts, water bottles, water containers, and vinyl due to their heat-resistant and mechanochemical properties. Among bisphenols, bisphenol A (BPA), which we often refer to as.....»»
Cosmic count exceeds expectation: Alpha Magnetic Spectrometer on ISS reveals surplus of cosmic rays
Cosmic rays confound scientists once again. The latest analysis of data collected by the Alpha Magnetic Spectrometer (AMS) on board the International Space Station has revealed a surprising surplus of cosmic rays made of deuterons—atomic nuclei mad.....»»
Genetic study uncovers onion bulb shape, size secrets
A new study by the Department of Plant and Agroecosystem Sciences, University of Wisconsin details the genetic mechanisms influencing the shape and volume of onion bulbs, along with the effects of daylength on the bulbing process. This research provi.....»»
Model suggests spewing metal nanorods into Mars" atmosphere could warm the planet by 30 K
A small team of engineers and geophysicists from Northwestern University, the University of Chicago, and the University of Central Florida has found, via modeling, that creating millions of metal nanorods from material on the Martian surface and then.....»»
Scientists take atomic look at a protein complex that grants access to our DNA
To transcribe the information contained in our genes or to repair the dozens of breaks that occur daily in our DNA, our enzymes must be able to directly access the DNA to perform their functions. However, in the cell nucleus, this access is limited b.....»»
Modeling Earth systems at a quintillion calculations per second
Climate models compute vast amounts of information about Earth's climate system—from small water droplets to large-scale weather patterns—to re-create past climate or predict future climate. Accurately re-creating how Earth's energy (measured in.....»»
Ticking time bomb: New modeling predicts huge increase in ticks across Scotland
The prevalence of ticks in Scotland will increase by a quarter under the most optimistic climate change scenario, according to new modeling by mathematicians at the University of Stirling......»»
Researchers reveal atomic-scale details of catalysts" active sites
The chemical and energy industries depend upon catalysts to drive the reactions used to create their products. Many important reactions use heterogeneous catalysts—meaning that the catalysts are in a different phase of matter than the substances th.....»»
Physicists report new insights into exotic particles key to magnetism
MIT physicists and colleagues report new insights into exotic particles key to a form of magnetism that has attracted growing interest because it originates from ultrathin materials only a few atomic layers thick. The work, which could impact future.....»»
Stem cell harmony: How solanaceae plants maintain homeostasis through receptor compensation
A pivotal study sheds light on the evolutionary conservation of stem cell homeostasis in Solanaceae, revealing how receptor compensation mechanisms ensure the continuous and orderly formation of plant organs. This research uncovers the genetic interp.....»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
