Cold molecules on collision course

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at the same time. Scientists around Dr. Martin Zeppenfeld from 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 ...

New type of nanosensor detects DNA building blocks

Researchers at Uppsala University and in Brazil have developed a new type of nanosensor that can detect single molecules. The nanosensor, comprising a combination of two different materials, has been used to identify the ...

Team simulates a magnetar to seek dark matter particle

MIT physicists are proposing a new experiment to detect a dark matter particle called the axion. If successful, the effort could crack one of the most perplexing unsolved mysteries in particle physics, as well as finally ...

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 ...
