Research Findings

When most people think about pi, they associate the mathematical constant with arcs and circles. Mathematicians, however, are accustomed to seeing it in a variety of fields. But two University physicists were still surprised to find it lurking in a quantum mechanics formula for the energy states of the hydrogen atom.

Scientists have been studying curiosity since the 19th century, but combining techniques from several fields now makes it possible for the first time to study it with full scientific rigor, according to the authors of a new paper.

By extracting information from Instagram images and hashtags, computer science researchers have shown they can expose patterns of underage drinking more cheaply and faster than conventional surveys.

Because sound travels much more slowly than light, we can often see distant events before we hear them. That is why we can count the seconds between a lightning flash and its accompanying thunder. Now researchers in the Department of Brain and Cognitive Sciences have shown that our brains can also detect and process sound delays that are too short to be noticed consciously, and that we use that information to fine tune what our eyes see when estimating distance.

Much like birds fly in flocks to conserve energy, dolphins swim in pods to mate and find food, and colonies of ants create complex nests to protect their queens, a new Medical Center study shows immune cells engage in coordinated behavior to wipe out viruses like the flu.

Nick Vamivakas, assistant professor of optics, thinks his team's work will make extremely sensitive instruments for sensing tiny forces and torques possible, and could also lead to a way to physically create larger-scale quantum systems known as macroscopic Schrödinger Cat states.

Since 2010, the best estimate of the age of Earth’s magnetic field has been 3.45 billion years. But now the Rochester researcher responsible for that finding has new data showing the magnetic field is far older.

Combined with the current weakening of Earth’s magnetic field, the data suggest that the region of Earth’s core beneath southern Africa may play a special role in reversals of the planet’s magnetic poles.

A new 30-year longitudinal study shows that the quantity of social interactions a person has in their 20s—and the quality of the social relationships they have in their 30s—can benefit his or her well-being later in life. The study participants, now in their 50s, took part in the Rochester-Interaction Record (RIR) study as college students in the 1970s and again as 30-year-olds in the 1980s.

The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.
