Defying gravity with the Brazil nut effect

Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

Study finds electrical fields can throw a curveball

MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately ...

Protons and antiprotons appear to be true mirror images

In a stringent test of a fundamental property of the standard model of particle physics, known as CPT symmetry, researchers from the RIKEN-led BASE collaboration at CERN have made the most precise measurements so far of the ...

Team records neutrinos from the Earth's mantle

(Phys.org)—A team of researchers working on the Borexino Collaboration at Gran Sasso National Laboratory in Italy is reporting that they have detected neutrinos emanating from the Earth's mantle. In their paper published ...

X-ray telescopes find black hole may be a neutrino factory

(Phys.org) —The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole.
