A close call of 0.8 light years
A recently discovered dim star likely passed some 70,000 years ago through our solar system’s distant cloud of comets known as the Oort Cloud. No other star is known to have ever approached our solar system this closely.

New self-stretching material developed at University of Rochester
Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.

Money, media coverage contribute to ‘negative’ campaigns
In a new study, Simon School professor used data science methodologies to take a closer look at what actually motivates candidates to “go negative.”

Curious monkeys share our thirst for knowledge
Monkeys are notoriously curious, and new research has quantified just how eager they are to gain new information, even if there are not immediate benefits.

A picture is worth 1000 words, but how many emotions?
During a political campaign voters will often share their views through pictures posted on social media. A human could recognize one as being a positive portrait of the candidate and the other one negative. Professor Jiebo Luo and his collaborators are training computers to make the same assessments.

An extra protein gives naked mole rats more power to stop cancer
Naked mole rats are small, hairless, subterranean rodents that have never been known to get cancer despite having a 30-year lifespan. A new protein discovered by biologist Vera Gorbunova may help explain why.

Generating Möbius strips of light
A collaboration between researchers from Canada, Europe, and Rochester has experimentally produced Möbius strips from the polarization of light, confirming a theoretical prediction that it is possible for light’s electromagnetic field to assume this peculiar shape.

New app would monitor mental health through “selfie” videos, social media
In a paper to be presented this week at the American Association for Artificial Intelligence conference in Austin, Texas, computer science professor Jiebo Luo and his colleagues describe a computer program that can analyze “selfie” videos recorded by a webcam as the person engages with social media.

Gigantic ring system around J1407b much larger, heavier than Saturn’s
Rochester astronomers, along with colleagues at the Leiden Observatory in the Netherlands have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn.

Laser-generated surface structures create extremely water-repellent metals
Scientists at the Institute of Optics have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings.
