A team of authors from MIPT, Kansas State University, and the U.S. Naval Research Laboratory have demonstrated that it is possible to fully absorb electromagnetic radiation using an anisotropic crystal. The observations are of fundamental importance for electrodynamics and will provide researchers with an entirely new method of absorbing the energy of electromagnetic waves. The paper has been published in Physical Review B.

For as much time as Americans spend saying it is the greatest country on Earth, a whole lot of people worry about creating safe spaces where free expression is not allowed, or protesting the behavior of people they don't like.

When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theoretical physicists, who have increasingly migrated toward making up stuff using math, now claim using such numbers that quantum theories of gravity must also have a 'rainbow' of sorts, composed of different versions of spacetime. They further predict that instead of a single, common spacetime, particles of different energies essentially sense slightly modified versions.

No one expects much of the social sciences, so a heavy reliance on undergraduate psychology student surveys to draw conclusions and resulting lack of reproducibility is dismissed, but the National Institutes of Health is nearly half of the federal government's and lack of reproducibility in biology and other life sciences is of greater concern for that reason.

If it can't be replicated, is it science? Sure, but it's a complex explanation for the public educated on the science process.

COLUMBUS, Ohio--Right now, astronomers are viewing a ball of hot gas billions of light years away that is radiating the energy of hundreds of billions of suns. At its heart is an object a little larger than 10 miles across.

And astronomers are not entirely sure what it is.

If, as they suspect, the gas ball is the result of a supernova, then it's the most powerful supernova ever seen.

Pasadena, CA--A team of astronomers, including Carnegie's Benjamin Shappee, Nidia Morrell, and Ian Thompson, has discovered the most-luminous supernova ever observed, called ASAS-SN-15lh. Their findings are published in Science.
