Tips of unusual particles from area might defy physicists’ basic design

Dangling from a balloon high above Antarctica, a particle detector has spotted something that standard physics is at a loss to explain. Two unusual signals seen by the detector, known as the Antarctic Impulsive Transient Antenna, or ANITA, can’t be attributed to any known particles, a team of physicists at Penn State reports online September…

Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly shiny, says Parno, a physicist at Carnegie Mellon University in Pittsburgh. “It was incredibly disorienting.” Now, electrons — thankfully immune to bouts of dizziness — traverse the…
