Magnetism offers new ways to create more powerful and energy-efficient computers, but the realization of magnetic computing on the nanoscale is a challenging task. A critical advancement in the field of ultralow power computation ...
Laser-wakefield accelerators have led to the development of compact, ultrashort X-ray or gamma-ray sources to deliver peak brilliance, similar to conventional synchrotron sources. However, such sources are withheld by low ...
In June 1348, people in England began reporting mysterious symptoms. They started off as mild and vague: headaches, aches, and nausea. This was followed by painful black lumps, or buboes, growing in the armpits and groin, ...
When the poet John Donne was struck down by a sudden infection in 1623 he immediately found himself alone—even his doctors deserted him. The experience, which only lasted a week, was intolerable. He later wrote: "As sickness ...
Chinese astronomers have conducted a gamma-ray and optical variability analysis of the blazar 3FGL J0449.4-4350. The new research, presented in a paper published March 25 on arXiv.org, reports the detection of possible quasi-periodic ...
Researchers at the National Institute of Standards and Technology (NIST) have discovered a surprising feature in two-dimensional (2-D) magnets, a new class of materials receiving a great deal of attention. Their finding is ...
Despite the progress in perovskite device efficiencies, these systems are not fully understood, in particular the frequency- and power-dependence of their response to light. Yu-Hwa Lo and colleagues at the University of California ...
The common phase transitions are those that occur as a function of temperature variation. Ice changes phase to become liquid water at 0 degrees Celsius. Liquid water changes phase to become water vapor at 100 degrees Celsius. ...
Charge density fluctuations are observed in all families of high-critical temperature (Tc) superconducting cuprates. Although constantly found in the underdoped region of the phase diagram at relatively low temperatures, ...
Light can be used not only to measure materials' properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity ...
