Heat cloak: a series of concentric rings lets heat propagating from left to right across a metallic sheet flow more readily around a thermally isolated disk than toward its center, leaving no sign of the disk in the temperature distribution on the right side; the colors represent temperatures measured with an infrared camera and are superimposed on a photo of the structure before the rubbery insulating material was added to the holes and gaps; the white lines connect points at the same temperature (R. Schittny / KIT)

The two observed events from August 2011, left, and January 2012, right. Each sphere represents a digital optical module; colors represent the arrival times of the photons where red indicates early and blue late times; the size of the spheres is a measure for the recorded number of photoelectrons (IceCube Collaboration)

IceCube Physicists Detect Two Record-Breaking Neutrinos

The times and vertical (y) annihilation locations (green dots) of 10,000 simulated antihydrogen atoms in the decaying magnetic fields. There is a tendency for the anti-atoms to annihilate in the bottom half of the trap, as shown by the black solid line. The blue dotted line includes the effects of detector azimuthal smearing on the average; the smearing reduces the effect of gravity observed in the data. The red circles are the annihilation times and locations for 434 real anti-atoms, as measured by the particle detector (A. E. Charman, the ALPHA Collaboration)
