Dig in to the Physics of Donuts for National Donut Day!

Before you ingest your annual delicious (possibly free) treat for Friday's annual celebration, why not learn about the physics of donuts? From topology to nuclear fusion, donuts are the physicist's breakfast pastry of choice. Not just because they’re tasty, but because their shape, the torus, is the subject of fascinating physics. Let's dig in to some of the multitude of donut sightings in physics, and answer the age-old question: Which rolls downhill faster, the holed donut or the filled doughnut?

Research Revisited: Knotted Hearts, Boson Stars, and Magnetic Particles

Sometimes, science news coverage can package research a little too neatly—with a clear beginning, middle, and end. In reality, research is a messy process with lots of back-and-forth, frustrations, and surprises. Scientists publish journal articles that highlight their results, but these are more like trail markers than final destinations. With this in mind, we’re introducing a new occasional feature on Physics Buzz, getting back in touch with scientists whose work we’ve profiled to see the twists and turns their research is taking.

European Space Agency Sponsors "Graffiti Without Gravity" Contest

On a cold day in Holland last week, 12 of the top street artists in Europe took their places in front of a chain link fence. Each artist faced a 2x2-meter canvas, and the possibility of being the first street artist to experience zero gravity. Not actually in space, but the first to experience weightlessness on one of the European Space Agency’s (ESA) parabolic flights—and to create art in that environment.

Listening for a Tornado's Infrasound Roar May Provide Better Warning Systems

In May of 2013, an EF5 tornado—the most powerful class—devastated the city of Moore, Oklahoma and the surrounding area, killing 24 people and wounding more than 200. The tornado leveled entire blocks of houses, destroyed schools and medical buildings, and tossed cars around, wreaking havoc on the city.

Art Meets Science and Light Turns Liquid at ARTECHOUSE's "Naked Eyes"

In the southwest corner of Washington DC, just across the river from the Pentagon, you'll find the unassuming entrance to one of the city's most fascinating places: ARTECHOUSE. Descend the seemingly endless staircase inside, and you'll emerge into a cavernous underground space where light and sound are twisted into dazzling, dynamic displays. This is Naked Eyes.

Physicists Introduce "Quantum Fraud" Detection Tests

It’s hard enough to identify a knockoff Louis Vuitton bag. When quantum computers hit the market, how will buyers know they’re not getting duped...or settling for something that isn’t quite as “quantum” as they think?

Laser Blasts Clear a Path Toward Clean Energy

“Fusion is the ultimate goal of energy research. It is clean, abundant, and safe,” says Dr. Luke Ceurvorst, a researcher at the University of Bordeaux in France. Recently, Ceurvorst and a team of collaborators from around the world reported new research results in the American Physical Society’s journal Physical Review E that will help scientists working to achieve nuclear fusion using a technique called fast ignition.

Using Springs to Bypass Traditional Speed Limits

Carnivorous trap-jaw ants clamp down on prey in a split second, with jaw speeds approaching 145 mph. Like a bullet from a gun, a chameleon's tongue shoots out with amazing accelerations to capture flies in midair. Animals like these are fascinating studies of physics and biology. How do these little guys pack so much speed compared to the rest of us?

Ask a Physicist: Is Time Travel Possible?

Luke, from California, wrote in last week:

I'm writing a research paper on time travel. Do you think time travel is possible?

Sports Science: How Much Energy is in a Record-Breaking Fastball?

A recent article on rookie Jordan Hicks claims he is the new hardest thrower in Major League Baseball (MLB). This piqued my interest for several reasons. The admittedly out-of-touch baseball fan in me immediately wanted to know who he is playing for (St. Louis Cardinals). The physicist in me started asking questions like what exactly does it mean that he’s the “hardest thrower?” How much energy does a ball thrown by Jordan Hicks have? How does this compare to other sports?

Scottish Scientists Just Made a Contact Lens That Lets You Shoot Lasers from Your Eyes

There's an old one-liner: "Laser eye surgery isn't nearly as cool as it sounds". Now, I don't know if this is fair—in my opinion, blasting a person's cornea back into shape so that they can see without glasses is one of the most awesome applications of laser tech. But as cool as that is, it's still not as cool as a surgery that gives you the ability to shoot lasers from your eyes—something that may be on the horizon thanks to researchers at Scotland's University of St. Andrews.
