Measuring very small changes in the brain’s magnetic fields could lead to a better understanding of maladies such as epilepsy, post-traumatic stress disorder, and traumatic brain injury, but the equipment used for such measurements today is bulky and expensive. Scientists and engineers at the Georgia Tech Research Institute (GTRI) want to address that issue by creating a new generation of atomic magnetometers based on clouds of rubidium atoms. (more…)

What is believed to be the smallest force ever measured has been detected by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. Using a combination of lasers and a unique optical trapping system that provides a cloud of ultracold atoms, the researchers measured a force of approximately 42 yoctonewtons. A yoctonewton is one septillionth of a newton and there are approximately 3 x 10²³yoctonewtons in one ounce of force. (more…)

Achieving a goal considered nearly impossible, JILA physicists have chilled a gas of molecules to very low temperatures by adapting the familiar process by which a hot cup of coffee cools.

JILA is a joint institute of the University of Colorado Boulder and the National Institute of Standards and Technology located on the CU-Boulder campus. (more…)
