The American Physical Society meeting on astronomy, astrophysics, cosmology and particle physics, the so-called April meeting, closes today in Washington DC. The IceCube Collaboration has presented brand new results on neutrino oscillations that are comparable in precision to long-baseline neutrino experiments. From WIPAC, many PhD students and more senior staff presented results about IceCube, including the masterclass, along with results on CTA and Fermi.

Those of us working with high-energy neutrinos always have great expectations for a new year, since the highest energy neutrino ever could show up or a joint detection of a neutrino and another cosmic messenger might point us to the much sought-after sources.

A recent work by Markus Ahlers, a John Bahcall fellow at WIPAC, has shown that fluctuations in the cosmic-ray dipole anisotropy can be understood once the local magnetic field and the presence of local CR sources are taken into account.

If learning that you can turn your smart phone into a cosmic-ray telescope was astonishing, you will be now stunned to read how you can use cosmic particles to peek into your phone and measure one of its components.
