Invisible particles 'seen' for the first time

A new optical effect in nanoscale disks of silicon, namely patterns of radiation that do not emit or scatter light, has been observed by A*STAR researchers and international collaborators. These modes, which have never before ...

Reaction rate of many molecules depends on their shape

Most molecules occur in several shapes, which may behave very differently. Using a sorting machine for molecules, a German–Swiss research team can now for the first time directly measure the various reaction rates of different ...

Crunching multiverse to solve two physics puzzles at once

The discovery of the Higgs boson was a landmark in the history of physics. It explained something fundamental: how elementary particles that have mass get their masses. But it also marked something no less fundamental: the ...

JILA spinning method confirms the electron still seems round

JILA physicists have for the first time used their spinning molecules technique to measure the "roundness" of the electron, confirming the leading results from another group and suggesting that more precise assessments are ...

JILA team develops 'spinning trap' to measure electron roundness

JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific ...

Minutest absolute magnetic field measurement

Every measurement is potentially prone to systematic error. The more sensitive the measurement method, the more important it is to make sure it is also accurate. This is key for example in measuring magnetic fields in state-of-the-art ...
