Microwave absorbers are a kind of material that can effectively absorb incident microwave energy to make objects invisible to radar; therefore they are commonly used in aircraft cloaking and warship stealth. Recently, as ...
Buried in the shallow soft mud of a dry California lake bed, a seismometer was able to detect the tiny tilts of the ground as it was pulled up by passing dust devils. The experiment, described online November 10 in the Bulletin ...
Observations by the NASA/ESA Hubble Space Telescope have taken advantage of gravitational lensing to reveal the largest sample of the faintest and earliest known galaxies in the Universe. Some of these galaxies formed just ...
You don't need to be a wizard to see the "Harry Potter" books come to life.
Researchers at The University of Alabama designed and made a material that manipulates the speed of light in a new, more effective way than previous methods, according to findings recently published in Scientific Reports ...
Success of the energy turnaround will depend decisively on the extended use of renewable energy sources. However, their efficiency partly is much smaller than that of conventional energy sources. The efficiency of commercially ...
Invisibility has long been one of the marvels in science fiction and fantasy – and more recently in physics. But while physicists have figured out the concept for how to make invisibility cloaks, they are yet to build a ...
The center of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it's also cloaked in so much dust that most stars within are rendered invisible. Harvard researchers are proposing a ...
Light, sound, and now, heat—just as optical invisibility cloaks can bend and diffract light to shield an object from sight, and specially fabricated acoustic metamaterials can hide an object from sound waves, a recently ...
(Â鶹ÒùÔº)—It was another good week for physics as a team with members from Germany, Austria and Australia conducted the most precise test of Lorentz symmetry for a photon and found that the speed of light is, indeed, constant—no ...
