In many materials, macroscopic magnetic properties emerge when microscopically small magnets align in a fixed pattern throughout the whole solid. In a…
Materials with a defined crystal structure are a familiar phenomenon in condensed matter physics. A crystal exhibits a regular structure, due to a periodic…
Quantum entanglement is always related to the microscopic world, but it also has striking macroscopic effects, such as the squeezing of light or…
Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of…
The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and…
“This is the first study directly connecting a galaxy's actively 'feeding' black hole to features found at much larger physical scales,” said lead researcher…
Each wavelength of light from the sun inherently carries information about the kind of process that emitted the light, so looking at soft X-rays provides a new…
Stars form within collapsing fragments of cold gas clouds. As the cloud contracts under its own gravity, its central region becomes denser and hotter. By the…
That's the situation now, at least, with the Square Kilometer Array (SKA), a radio telescope planned for Africa and Australia that will have an unprecedented…
Silicon solar cells dominate 90 percent of the global photovoltaic market today, yet the record power conversion efficiency of silicon photovoltaics has…
In an experiment at the Department of Energy's SLAC National Accelerator Laboratory, scientists precisely measured the temperature and structure of aluminum as…
Like other first-generation bio-robots, the new nanobot engineered at the University of Illinois at Chicago is a far cry from Robocop. It's a robotic germ.
Some of the age’s greatest astronomers, including Hevelius — the father of lunar cartography — and Cassini, carefully documented the appearance of a new star…
Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths–planets larger than Earth…
Down at the South Pole, where temperatures drop below negative 100 degrees Fahrenheit and darkness blankets the land for six months at a time, the South Pole…
Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using “twisted light.” This…
