  • Lucas Hackl has been selected to serve as the APS student representative on the Science and Human Rights Coalition of the American Association for the Advancement of Science (AAAS). The coalition seeks to encourage the "science, engineering and health communities" to "embrace human rights as an area suitable for and deserving of robust inquiry, and become an influential voice in the defense of human rights."
  • The IceCube 2014 discovery of a 2 PeV cosmic neutrino event ("Big Bird") has been featured by APS as one of the Top 10 Physics News Stories in 2014.

Vanquishing Infinity: Old Methods Lead to New Approach to Finding Quantum Theory of Gravity

ScienceDaily (Aug. 21, 2009) - "Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure. When physicists try to calculate the properties of a quantum theory of gravity, they find quantities that become infinite - infinities that are so bad they can't be removed by mathematical gambits that work in other areas of physics."

"Now, Zvi Bern, John Joseph Carrasco, and Henrik Johanssen at UCLA, Lance Dixon at the Stanford Linear Accelerator Center, and Radu Roiban at The Pennsylvania State University have found a way to carry out a new set of gravity calculations with the help of an older theory that has been known since the 1980s to be finite."
