Proton Dripping Tests a Basic Force of Nature

May 9, 2011

Like gravity, the strong interaction is a fundamental force of nature. It is the essential “glue” that holds together atomic nuclei (composed of protons and neutrons) to form atoms, the building blocks of nearly all the visible matter in the universe. Despite its prevalence in nature, researchers are still searching for the precise laws that govern the strong force. However, the recent discovery of an extremely exotic, short-lived nucleus called fluorine-14 in laboratory experiments may indicate that scientists are gaining a better grasp of these rules.

LED Lighting Comes out of the Dark

April 29, 2011

Despite being cool, ultra-efficient and long lasting, the light-emitting diode (LED) has yet to conquer the general lighting market due to a problem called “efficiency droop.” New findings from simulations carried out at the National Energy Research Scientific Computer Center (NERSC) have unearthed droop’s elusive cause, researchers say, paving the way for wider LED use.

Supercomputer Cracks "Impossible" Calculation

April 25, 2011

Australian researchers have done the impossible—they’ve found the sixty-trillionth binary digit of Pi-squared! The calculation would have taken a single computer processor unit (CPU) 1,500 years to calculate, but scientists from IBM and the University of Newcastle managed to complete this work in just a few months on IBM’s BlueGene/P supercomputer, which is designed to run continuously at 1petaflop/s—that’s one quadrillion calculations per second!

Boosting the Next Wave of Accelerators

March 17, 2011

Albert Einstein’s most famous thought experiment is proving its worth once again as researchers use it to help speed up the modeling (and thus design) of so-called “tabletop” accelerators. Read More »
