Close encounters of a tidal kind could lead to cracks on icy moons

Close encounters of a tidal kind could lead to cracks on icy moons

May 25, 2016

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.

A digital ‘Rochester Cloak’ to fit all sizes

A digital ‘Rochester Cloak’ to fit all sizes

May 19, 2016

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.

Researchers demonstrate record optical nonlinearity

Researchers demonstrate record optical nonlinearity

April 28, 2016

A team led by Robert Boyd has demonstrated that the transparent, electrical conductor indium tin oxide can result in up to 100 times greater nonlinearity than other known materials, a potential ‘game changer’ for photonics applications.

A new way to determine the age of stars?

A new way to determine the age of stars?

March 22, 2016

Rochester researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve. Their framework helps explain how the rotation of stars, their emission of x-rays, and the intensity of their stellar winds vary with time. According to Eric Blackman, professor of physics and astronomy, the work could also “ultimately help to determine the age of stars more precisely than is currently possible.”

Can a computer tell if you’re drinking while tweeting?

Can a computer tell if you’re drinking while tweeting?

March 21, 2016

Computer science graduate student Nabil Hossain and his collaborators have taught computers to analyze tweets about drinking to determine if people were actually drinking at the time they were tweeting and if they were tweeting from home or some other location.

Paying attention to words, not just images, leads to better captions

Paying attention to words, not just images, leads to better captions

March 15, 2016

A team of University and Adobe researchers is outperforming other approaches to creating computer-generated image captions in an international competition. The key to their winning approach? Thinking about words – what they mean and how they fit in a sentence structure – just as much as thinking about the image itself.
