Physicists have devised a way to take pictures using light that has not interacted with the object being photographed.
This form of imaging uses pairs of photons, twins that are ‘entangled’ in such a way that the quantum state of one is inextricably linked to the other. While one photon has the potential to travel through the subject of a photo and then be lost, the other goes to a detector but nonetheless ‘knows’ about its twin’s life and can be used to build up an image.
Decades of experiments have verified the quirky laws of quantum theory again and again. So when scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, a physicist at the University of Rochester was determined to find an explanation.
The materials in the collection, which date from 1881 through the turn of the century, include more than 60 autographed and typed letters, signed cabinet cards and photographs, and other related material, and will supplement an existing collection of letters between the two women held in the school library’s Department of Rare Books, Special Collections, and Preservation.
Dr. Kessler, the author of an article reviewing the findings in the same journal, said that because the Atlantic margin was unaffected by tectonic activity or other factors, it should prove to be a convenient location to conduct long-term studies of links between climate change and methane releases.
UR has already issued an update of its sexual misconduct policy, saying it is moving toward an “affirmative consent” model, which requires explicit consent from both individuals engaged in sexual activity. The college also tries to hammer home the importance of consent with a skit, “Red Light, Green Light,” which will be performed as part of this week’s orientation for first-year students.
Pictured at left is the queen ant of the parasitic species Mycocepurus castrator. This ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.
Kidney injury can be added to the list of possible harms related to use of three antipsychotic medications often prescribed to treat symptoms of dementia, a new study finds. “The side effect profile with antipsychotics is particularly concerning, so there is ample evidence to worry about their use in older adults unless they’re absolutely necessary,” said Dr. Anton Porsteinsson, director of Alzheimer’s disease care, research and education.
A University of Rochester Medical Center cardiology research team has won a $4 million National Institutes of Health grant to study a genetic disorder that causes heart arrhythmias and can lead to sudden death, URMC officials said Tuesday. Led by Arthur Moss M.D., the cardiology team plans a five-year study of Long QT Syndrome, type 3.
I asked a group of students who, if anyone, planned to migrate to the United States. I expected a few hands to go up. Instead, every single child in the room raised his or her hand. — Daniel Reichman, professor of anthropology at the University of Rochester and author of The Broken Village: Coffee, Migration, and Globalization in Honduras.
