The use of multimode optical fibers to boost the information capacity of the Internet is severely hampered by distortions that occur during the transmission of images because of a phenomenon called modal crosstalk.
However, University of Rochester researchers at the Institute of Optics have devised a novel technique, described in a paper in
Nature Communications, to flip the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion. Researchers at the University of South Florida and at the University of Southern California collaborated on the project.

NEW YORK, May 5, 2021 Rein Ulijn, founding director of the Nanoscience Initiative at the Advanced Science Research Center at The Graduate Center, CUNY (CUNY ASRC) and Einstein Professor of Chemistry at Hunter College, has been awarded a U.S. Department of Defense s Vannevar Bush Faculty Fellowship the agency s most prestigious single-investigator award. The fellowship supports top-tier researchers at U.S. universities whose high-risk, high-reward work is of strategic importance to the Department of Defense. The five-year fellowship will provide $3 million to support Ulijn s work to understand how complex mixtures of molecules acquire functionality, and to repurpose this understanding to create new nanotechnology that is inspired by living systems.
When it comes to chess, computers seem to have nothing left to prove.
Since IBM’s Deep Blue defeated world chess champion Garry Kasparov in 1997, advances in artificial intelligence have made chess-playing computers more and more formidable. No human has beaten a computer in a chess tournament in 15 years.
In new research, a team including Jon Kleinberg, the Tisch University Professor of Computer Science, developed an artificially intelligent chess engine that doesn’t necessarily seek to beat humans – it’s trained to play like a human. This not only creates a more enjoyable chess-playing experience, it also sheds light on how computers make decisions differently from people, and how that could help humans learn to do better.
