For five jam-packed days, physicists from around the world gathered in San Antonio, Texas to share their research with colleagues. The American Physical Society’s annual March Meeting featured over 8,600 presentations and posters, and brought together more than 10,000 physicists and physics students.
Most of the talks were highly technical, and of interest only to people deeply involved in their respective subjects. But others were appealing to people beyond the physics community. Here are a few stories about the March Meeting talks that you might spot in recent news outlets.
The Best Place to Hide for the Coming Zombie Apocalypse
Where is the safest place to be in the event of a fictional zombie outbreak? A statistical analysis performed by Alex Alemi and his colleagues at Cornell University suggests that it’s best to head for the hills — ideally the Northern Rocky Mountains. In a simulation of an outbreak across the United States, the majority of the population would be infected within 28 days, except in small remote pockets such as the Rocky Mountains. While a zombie outbreak is of course fictitious, this same approach can be used to model the outbreak of any disease, using statistical physics techniques.
This research received quite a bit of press attention during the March Meeting, including local TV crews and interviews with NPR.

James Wynne from IBM demonstrated extreme precision from a powerful type of laser known as an excimer laser that he helped pioneer back in the 1980s.

At the March Meeting, Wynne presented a history of lasers and his career work with IBM.

Jungle Gyms for Cells
Soft, stretchy electronics have a huge range of potential medical applications within the human body, from health monitors that take the form of temporary tattoos to sensors that wrap around a heart.
John Rogers from the University of Illinois at Urbana-Champaign showcased his work making “pop-up” 3D scaffolds in a variety of shapes using device-grade silicon. He hopes this work can help bridge the gap between traditionally-rigid silicon electronics and the soft nature of biological scaffolds.

Smoothing Oil Flow in Pipelines
Huge energy savings could be gained simply by applying an electric field to oil at intervals along a pipeline. Rongjia Tao from Temple University has tested this idea on various oil pipelines around the world, including a section of the Keystone pipeline near Wichita, Kansas and has shown that the electric field aligns oil particles into chains that have the effect of reducing the thickness and turbulence of oil. A smoother oil flow means much less energy is needed to pump the oil from point A to point B.

Why is the Eyeball Reverse-Wired?

The human eye has photoreceptors in the back of the eyeball, counterintuitively obstructed by nervous fibers and the retina in front. Erez Ribak from the Technion – Israel Institute of Technology has now explained the strange reverse-wiring of the eyeball, showing that certain cells which cross the retina actively direct and concentrate light onto the photoreceptors, rather than simply getting in the way.
