Do electrons have a fourth property in addition to mass, charge and spin, as popular physics theories such as supersymmetry predict? Researchers from Germany, the Czech Republic and the United States ...

In Förster resonance energy transfer (FRET), energy non-radiatively transfers from a blue-shifted emitter to a red-shifted absorber by dipole–dipole coupling. This study shows that plasmonics enables ...

Measuring zero: scientists have lowered the previous upper limit of the neutron’s electric dipole moment by 40%. (Courtesy: IOP Publishing) For more than 60 years, physicists have been searching for a ...
