Stephen Reynolds is an astrophysicist at North Carolina State University.

In the age of the Internet, it sometimes seems as though no questions remain unanswered. But for Stephen Reynolds, the mystery is only beginning.

Physics World recently named its top ten breakthroughs for the year, and research from North Carolina State University was on the list. NC State, along with the University of Rochester in New York, has been working on research into how neutrinos can be used for tricky communications, like talking to submerged submarines or interstellar travelers.

The origins of the universe are being uncovered in Chapel Hill, NC thanks to Laura Mersini-Houghton, a cosmologist and theoretical physicist at the University of North Carolina. Her work delves even deeper into how our world came to be than the Big Bang theory.

That's the sound of a penny rolling round and round in a device called a gravity funnel. This was recorded at the Natural Science Center in Greensboro using WUNC's Make Radio iPhone app. It's part of a collaboration with the North Carolina Science Festival. You've likely seen this game, the coin launches from the top of a big round funnel and then spins, on edge, down to the collection jar underneath the hole at the bottom of the cone.
