New record at ultracold neutron source in Mainz
Jan 19, 2018 (SPX)
Neutrons do not normally exist in a free state but are instead bound as neutral particles within the atomic nucleus. Free neutrons are unstable and decay with a...
DARPA Program Aims to Extend Lifetime of Quantum Systems
Jan 19, 2018 (SPX)
This is particularly the case as sensor and device performance continue to improve and approach their fundamental limits. It is not lost on DARPA that controlli...
Odd behavior of star reveals lonely black hole hiding in giant star cluster
Jan 19, 2018 (SPX)
Globular star clusters are huge spheres of tens of thousands of stars that orbit most galaxies. They are among the oldest known stellar systems in the Universe ...
Astronomers Measure More Black Holes, Farther Away
Jan 17, 2018 (SPX)
The results, being presented at the American Astronomical Society (AAS) meeting in National Harbor, Maryland and published in the Astrophysical Journal, represe...
Watchmakers hope to make Chinese market tick
Jan 17, 2018 (AFP)
Through online stores, social networks, and brand new boutiques in China's central cities, manufacturers at the international luxury watchmakers show SIHH are h...
Black hole spin cranks-up radio volume
Jan 17, 2018 (SPX)
Black holes absorb light and all other forms of radiation, making them impossible to detect directly. But the effects of black holes, in particular accretion di...
Researchers catch supermassive black hole burping
Jan 12, 2018 (SPX)
CU Boulder Assistant Professor Julie Comerford, who led the study, said the supermassive black hole under study appears to have belched - essentially blasting o...
Astronomers detect 'whirlpool' movement in earliest galaxies
Jan 12, 2018 (SPX)
An international team led by Dr. Renske Smit from the Kavli Institute of Cosmology at the University of Cambridge used the Atacama Large Millimeter/submillimete...
Black hole breakthrough: new insight into mysterious jets
Jan 11, 2018 (SPX)
Advanced simulations created with one of the world's most powerful supercomputers show the jets' streams gradually change direction in the sky, or precess, as a...
Supermassive Black Holes Can Overpower Even the Smallest Galaxies
Jan 10, 2018 (SPX)
The results, being presented at the American Astronomical Society (AAS) meeting in National Harbor, Maryland on Thursday and soon to be published in the Monthly...
MSU scientists created a magnetic trap for neutrons
Jan 10, 2018 (SPX)
Waveguides are quite a broad class of objects utilized in many spheres of life, from telecom (optic wave guides) to medicine (a stethoscope is a sound wave guid...
Black hole research could aid understanding of how small galaxies evolve
Jan 10, 2018 (SPX)
These giant black holes are over a million times more massive than the sun and sit in the centre of galaxies sending out powerful winds that quench the star-mak...
Two Astronomers, 100 Years Apart, Use Stars to Measure the Universe
Jan 10, 2018 (SPX)
"It's been fascinating to work with such historically significant stars," says Kate Hartman, an undergraduate from Pomona College who announced the results at t...
Quantum 'spooky action at a distance' becoming practical
Jan 08, 2018 (SPX)
They demonstrated that the effect, also known as quantum nonlocality, can still be verified even when many of the photons are lost by absorption or scattering a...
Four-dimensional physics in two dimensions
Jan 04, 2018 (SPX)
A paper describing the research appears January 4, 2018 in the journal Nature along with a paper from a separate group from Germany that shows that a similar me...
Supermassive black holes control star formation in large galaxies
Jan 02, 2018 (SPX)
Every massive galaxy has a central supermassive black hole, more than a million times more massive than the sun, revealing its presence through its gravitationa...
Quantum noise reduction method for enhanced precision in atomic clocks
Dec 28, 2017 (SPX)
This is because at that scale, there are effects that don't exist at larger scales. As such, finding ways to reduce quantum noise can enhance the precision of m...
GAMBIT narrows the hiding places for 'new physics'
Dec 27, 2017 (SPX)
Is it possible for today's apparatus to detect the elementary particles of 'new physics' that are capable of explaining such mysteries as the nature of dark mat...
