Researchers at Argonne National Laboratory discovered that magnetic vortices in nickel-iron alloy exhibit unique behavior when trapped within lithographically patterned ferromagnetic structures. The study, published in Nature Physics, shows promise for the development of faster and more energy-efficient electronic devices.
Researchers at Johns Hopkins University have developed a new type of magnetic memory cell that can store large amounts of information in a densely packed area. The cells, made up of tiny cobalt or nickel rings, are immune to stray magnetic fields and can be controlled on-demand.
Researchers create an optical vortex mask that eliminates starlight, allowing for direct observation of nearby planets. The device successfully images Saturn and its rings, paving the way for future exoplanet detection projects like the Terrestrial Planet Finder.
Pitt researchers Yadin Y. Goldschmidt and Eduardo Cuansing used computer simulations to find direct evidence of new vortex patterns in superconductors. These findings show that the vortices can behave differently in the presence of columnar defects, leading to two-stage melting instead of one at higher temperatures.
Researchers predict a 10-degree Celsius shift in Jupiter's average temperature as atmospheric whirlpools vanish, causing jet streams to become unstable. This will spawn new vortices and signal the end of Jupiter's current 70-year climate cycle.
A Purdue University earth scientist has discovered that damaging winds within thunderstorms can form on the north side of a storm's path, rather than at its apex. This finding could lead to more accurate storm warnings and improved public safety.
Researchers used computer simulations to study explosions in high-energy materials, predicting primary chemical reactions and mechanical stresses. Meanwhile, new models accurately predict lung crackle sounds, potentially aiding diagnosis of pulmonary dysfunctions.

Researchers have developed a method to control the behavior of ultra-cold substances, which could lead to significant advancements in quantum computing and precise time measurements. By manipulating the material's density and vortex patterns, scientists can create unique flow patterns that defy traditional solid or liquid states.
The Arctic Oscillation has strengthened in recent decades, leading to increased warmth over the Northern Hemisphere. Recent computer-model simulations suggest a possible link between the AO and global warming.
Research found that a warm polar winter made it easier for ozone to accumulate in the Arctic stratosphere, as warmer air prevented the formation of polar stratospheric clouds. This prevented the breakdown of ozone molecules, leading to higher levels of ozone in the lower stratosphere.
Researchers at the University of Illinois found a statistical correlation between weak polar vortices and severe cold outbreaks. The study proposes a dynamical mechanism where stratospheric forcing stimulates pre-existing modes of variability in the troposphere.
A team led by Sean Ling observes melting in a superconductor using a single crystal of niobium and neutron imaging. The result shows that vortices can melt into a liquid at a specific temperature, paving the way for further studies on the mechanism of melting.
Researchers at Purdue University are creating plastic and mathematical models to analyze the aerodynamic sound of human speech. They aim to predict the consequences of surgery on the throat and develop a method to better synthesize and characterize voices for robotics and voice-recognition purposes.
Researchers propose using an alternating current to pattern a sawtooth-like structure on a superconductor, directing vortices away from the device. This method avoids sophisticated material processing and can be used in both low-temperature and high-temperature superconductors.
Researchers at Technion-Israel Institute of Technology have discovered that small lasers can produce tiny optical vortices, also known as whirlpools of light, which could be used to transmit information at high speeds over long distances. The findings have practical applications in improving optical fiber communications and may also be...
Researchers John Abrahamson and Peter Coleman successfully created stable fireballs in a mini tornado using liquefied petroleum gas, challenging existing theories about ball lightning. The experiment may have industrial applications and shed new light on unexplained UFO sightings.
A record-breaking Arctic polar vortex in 1996-1997 led to significant ozone depletion, comparable to the Antarctic's early 1980s levels. The study revealed that chemical interactions between nitric oxide and nitrogen dioxide chemistry played a crucial role in the depletion.
The University of Michigan's VORTEX experiment, launched on the Space Shuttle Endeavour, investigates fluid atomization in microgravity. The study aims to answer fundamental questions about the process by which liquids are converted into tiny droplets.
Wake vortices, created by large commercial aircraft, will be studied at Baltimore Washington International Airport (BWI) to develop a reliable detection system. The system aims to increase airport safety by providing controllers with observed vortex location and intensity information.
