New Image Reveals Detailed Structure of Matter Being Thrown Off Betelgeuse Red Star

Astronomers have released a new image of the outer atmosphere of Betelgeuse – one of the nearest red supergiants to Earth – revealing the detailed structure of the matter being thrown off the star.

CERN LHCb Collaboration Submits Paper on First Observation of Matter-Antimatter Asymmetry

The LHCb collaboration at CERN today submitted a paper to Physical Review Letters on the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s. It is only the fourth subatomic particle known to exhibit such behaviour.

Distant High-Energy Blazar Displays Highly Unusual Emission Spectrum

Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of a blazar known as PKS 1424+240 show that it is the most-distant known source of very high-energy gamma rays. But its emission spectrum appears highly unusual.

Dark Matter to Be Probed by Leading Astrophysicts

Uncloaking the secrets of dark matter in the universe is a cosmological conundrum puzzling some of the brightest astrophysicists.

Unique Properties Discovered in Quantum Well Tube Nanowires

New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with something that's 1,000 times thinner than the typical human hair – a semiconductor nanowire.

Ferocious Star-Formation in Rare Galaxy

Astronomers have found a galaxy turning gas into stars with almost 100 percent efficiency, a rare phase of galaxy evolution that is the most extreme yet observed. The findings come from the IRAM Plateau de Bure interferometer in the French Alps, NASA's Wide-field Infrared Survey Explorer and NASA's Hubble Space Telescope.

Quantum Nature of Macroscopic Spin Universal to Collective Spin Excitations in Conductive Systems

An international team of scientists, including University of York physicist Dr Irene D’Amico, has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level.

New Protocol Supports 'Noisy Network' Approach for Advancing Quantum Computers

Quantum physics promises faster computations but today's most advanced quantum computers operate with fewer than 20 quantum bits (qubits). To realise the technology's full potential will require much larger machines, and researchers are busy planning how to build them. A new protocol designed by researchers in Singapore and the UK lends support to a 'noisy network' approach. The work is published in Nature Communications.

New Method to Monitor Asteroid Collisions in Interplanetary Space

Many collisions occur between asteroids and other objects in our solar system, but scientists are not always able to detect or track these impacts from Earth. The "rogue debris" created by such collisions can sometimes catch us by surprise.

Physicists Find Possible Hints of Dark Matter

Physicists operating an underground experiment in Minnesota reported last week that they have found possible hints of dark matter. The Cryogenic Dark Matter Search (CDMS) experiment detected three events with the characteristics expected of dark matter, Kevin McCarthy, a PhD student in physics at MIT, reported at the American Physical Society meeting in Denver.
