Until now, it was thought the cracks on icy moons such as Pluto’s Charon were the result of processes like plate tectonics. But new computer models suggest that the pull exerted by another object might have been the cause.
Using the same mathematical framework as the Rochester Cloak, researchers have been able to use flat screen displays to extend the range of angles that can be hidden from view. Their method lays out how cloaks of arbitrary shapes, that work from multiple viewpoints, may be practically realized in the near future using commercially available digital devices.
The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.
The National Science Foundation has granted its most prestigious award in support of junior faculty, the Faculty Early Career Development (CAREER) Program, to three University researchers: Antonio Badolato, Danielle Benoit, and Michael Neidig.
Some of the most energetic phenomena in the universe produce high-energy gamma rays, and a new observatory in Mexico aims to expand the catalog of known gamma ray sources.
In what they call a “weird little corner” of the already weird world of neutrinos, physicists have found evidence that these tiny particles might be involved in a surprising reaction. In an experiment conducted with the international MINERvA collaboration at Fermilab, physics professor Kevin McFarland and his students and colleagues provide evidence that neutrinos can sometimes interact with a nucleus but leave it basically untouched, resulting in a new particle being created out of a vacuum.
In the vastness of the universe, it’s very likely that other life forms have also evolved to an extent that they altered the atmosphere of their planets. If we looked at climate change as a predictable consequence of intelligent life — and a process that tends to follow specific patterns — we might be better equipped to figure out how to stop it.
We’re still a long way from donning real invisibility cloaks, but by working out a better way to bend light, scientists from the University of Rochester can make movable objects invisible to the viewer — multi-directionally, and in three dimensions.
Physicists have figured out the optical parameters for a magic trick they characterize as a kind of “invisibility cloak” — and unlike most magicians, they’re only too willing to show you how it’s done. “We just figured a very simple way of doing that can just be using standard lenses, and things that we normally find in the lab,” physics professor John Howell said in a video explaining the setup.
