It’s like a very small invisibility cloak made of glass.
Researchers at the University of Rochester seem to be taking the words of science fiction writer Arthur C. Clarke’s to heart: “any sufficiently advanced technology is indistinguishable from magic.”
Scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed by physics professor John Howell and graduate student Joseph Choi, not only overcomes some limitations of previous devices, but uses inexpensive, readily available materials in a new way. “This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking,” said Choi.
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.
Some critics claim that a 2012 University of Rochester study calls the Marshmallow Test into question. Children in a reliable environment (where they could trust that the delayed reward would materialize) waited four times longer than children in the unreliable group. Were the kids in your test simply making a rational choice and assessing reliability? And wouldn’t that factor be outside the scope of the original Marshmallow Tests?
Biology researchers Vera Gorbunova and Andrei Seluanov report that the “jumping genes” in mice become active as the mice age when a multi-function protein stops keeping them in check in order to take on another role. A protein called Sirt6 is needed to keep the jumping genes—technically known as retrotransposons—inactive.
Exercise itself is sure to reinvigorate you when you’re feeling sluggish, but fresh air can boost the effect. A 2009 study from the University of Rochester found that just 20 minutes outside can rev you up as much as a cup of coffee, The Telegraph reported.
The researchers, who hailed from Duke, Ohio State, Dartmouth, the University of Rochester and Stanford, traced the presence of noble gases in the methane that emerged in peoples’ houses in fracking regions in Pennsylvania and Texas to distinguish between gas from natural seeps and drilling sites. Noble gases like helium, neon, and argon “stick” to natural gas and move with it, unchanged, as it passes through different layers of earth.
A new report examines the host of potential health-related issues that communities in areas of the country suitable for natural gas extraction may face and provides direction for future research.
Biologist Vera Gorbunova studies these creatures at the University of Rochester. She says naked mole rat societies, which can reach 300 individuals, are more like dictatorships than monarchies because anyone with the gumption can ascend the throne.
“I was nervous when I went to my first sleep conference,” says Dr. Maiken Nedergaard, the chatty and inquisitive co-director of the Center for Translational Neuromedicine at the University of Rochester. “I was not trained in sleep, and I came to it from the outside.” In fact, as a busy mother and career woman, she saw sleep the way most of us probably do: as a bother. “Every single night, I wanted to accomplish more and enjoy time with my family, and I was annoyed to have to go to bed.”
