Spinning Magnetar Suddenly Slows Down

Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects.

Sodium Levels Predict How Stars End Their Lives

The way in which stars evolve and end their lives was for many years considered to be well understood. Detailed computer models predicted that stars of a similar mass to the Sun would have a period towards the ends of their lives — called the asymptotic giant branch, or AGB — when they undergo a final burst of nuclear burning and puff off a lot of their mass in the form of gas and dust.

Crucial Ingredient of High-Temperature Superconductivity Found in Different Class of Materials

Physicists at the University of Arkansas have collaborated with scientists in the United States and Asia to discover that a crucial ingredient of high-temperature superconductivity could be found in an entirely different class of materials.

Neutron Star Rapidly Drops Speed of Rotation

One of the densest objects in the universe, a neutron star about 10,000 light years from Earth, has been discovered suddenly putting the brakes on its spinning speed. The event is a mystery that holds important clues for understanding how matter reacts when it is squeezed more tightly than the density of an atomic nucleus -- a state that no laboratory on Earth has achieved.

Researchers Identify Threshold at Which Entanglement Occurs in Large Quantum Systems

Entanglement is a property in quantum mechanics that seemed so unbelievable and so lacking in detail that, 66 years ago this spring, Einstein called it “spooky action at a distance.”

Kiel-Greifswald Plasma Physics Research Center Granted a Third Funding Period

The Collaborative Research Centre TRR 24 "Fundamentals of Complex Plasmas" has been granted a third funding period and new 6.5 million euros by the German Science Foundation (DFG). The DFG decision is based on the positive evaluation by a high-rank international review panel.

Germanium Delivery Begins in Effort to Understand Puzzling Imbalance between Matter and Antimatter

The Department of Energy's Oak Ridge National Laboratory has begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang.

Best Measurement of Evolution of Extragalactic Background Light Over the Past 5 Billion Years

How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies that ever existed throughout cosmic history is still speeding through the Universe today.
