New Theory Describes How Clusters of Galaxies May Regulate Star Formation

A handful of new stars are born each year in the Milky Way, while many more blink on across the universe. But astronomers have observed that galaxies should be churning out millions more stars, based on the amount of interstellar gas available.

Quantum Device That Corrects its Own Errors, Holds Promise for Quantum Computing

When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers by comparison.

Cosmic Precipitation Can Slow Down Growth of Galaxies Containing Supermassive Black Holes

Using NASA's Chandra X-ray Observatory, astronomers have found that the growth of galaxies containing supermassive black holes can be slowed down by a phenomenon referred to as cosmic precipitation.

Galactic 'Rain' Linked to Ability of Galaxies to Create Stars

Some of the galaxies in our universe are veritable star nurseries. For example, our own Milky Way produces, on average, at least one new star every year. Others went barren years ago, now producing few if any new stars.

Second Laws of Thermodynamics for Quantum Systems

It's time to update a physical law discovered by a 19th Century scientist interested in making better steam engines. Researchers from the Centre for Quantum Technologies and their international collaborators have shown that the 'second law of thermodynamics' has a host of cousins at small scales.

New Method Measures Characteristic Microwaves to Read Out Orientation of Magnetic Vortices in Nanodisks

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Forschungszentrum Jülich (FZJ) together with a colleague at the French Centre National de la Recherche Scientifique (CNRS) in Strasbourg have found a new way to electrically read out the orientation of magnetic vortices in nanodisks. Their new method relies on measuring characteristic microwaves emanating from the vortices.

Physicists Successfully Characterize Electromagnetic Properties of Skyrmion-Materials

Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behavior. This lays the foundation for future electronic components with purpose-designed properties.

New Technique to Analyze Clouds on Exoplanets

Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system, thanks to researchers at MIT.

Study Contributes to Determination of Nature of Dark Matter

Recent research conducted by scientists from the University of Granada can contribute to determine the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, dark matter amounts to more than 80% of the universe.
