New, Mysterious Class of Star Cluster

Globular star clusters are huge balls of thousands of stars that orbit most galaxies. They are among the oldest known stellar systems in the Universe and have survived through almost the entire span of galaxy growth and evolution.

Researchers Reveal Performance Degradation Mechanism of Electrodeless, Helicon Plasma Thruster

A part of the performance degradation mechanism of the advanced, electrodeless, helicon plasma thruster with a magnetic nozzle, has been revealed by the research group of Dr. Kazunori Takahashi and Prof. Akira Ando at Tohoku University's Department of Electrical Engineering.

A Space with the Weakest Magnetic Field in the Solar System

Magnetic fields easily penetrate matter. Creating a space practically devoid of magnetic fields thus presents a great challenge. An international team of physicists has now developed a shielding that dampens low frequency magnetic fields more than a million-fold.

Live Viewing of Attosecond Recombination of Electron Shells in Molecules

The recombination of electron shells in molecules, taking just a few dozen attoseconds (a billionth of a billionth of a second), can now be viewed "live," thanks to a new method developed by MIPT researchers and their colleagues from Denmark, Japan and Switzerland. An article detailing the results of their study has been published in the journal Nature Communications.

Strangulation Could be the Primary Cause of Galactic Death

As murder mysteries go, it's a big one: how do galaxies die and what kills them? A new study, published today in the journal Nature, has found that the primary cause of galactic death is strangulation, which occurs after galaxies are cut off from the raw materials needed to make new stars.

CMS-LHCb Joint Analysis Establishes Extremely Rare Decay of Bs Particle into Two Muons

Two experiments at the Large Hadron Collider at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have combined their results and observed a previously unseen subatomic process.

Swing-Dancing' Electrons Could Help Develop New Quantum Devices

A research team led by the University of Pittsburgh's Jeremy Levy has discovered electrons that can "swing dance." This unique electronic behavior can potentially lead to new families of quantum devices.

Researchers Design and Operate Working Superconducting Qubit Devices

Professor Oleg Astafiev, jointly appointed Professor at Royal Holloway and Visiting Professor at the National Physical Laboratory (NPL), and his team of researchers, have designed, built and operated the first working superconducting qubit devices in the UK.

New Magnetic Shield Achieves Extremely Low Magnetic Field over a Large Volume

The Standard Model of particle physics, sometimes called "The Theory of Almost Everything," is the best set of equations to date that describes the universe's fundamental particles and how they interact.

Topological State of New Family of Materials can be Observed Directly

They are 'strange' materials, insulators on the inside and conductors on the surface. They also have properties that make them excellent candidates for the development of spintronics ('spin-based electronics') and more in general quantum computing. However, they are also elusive as their properties are extremely difficult to observe.
