At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn't understand how they form. Now, for the first time, a supercomputer simulation -- so detailed it took a full year to run --...

Naturally occurring DNA is a thicket, but its high tension and constant motion make it shuttle large transcriptions factors through its dense windings to binding sites, where the factors go to work. Researchers back this hypothesis with a very large, unique simulation. Here, DNA is in gray, transcription factor LacI in green. CREDIT Georgia Tech / Edmond Chow / Jeffrey Skolnick

A new supercomputer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain materials. “Supermassive black holes have a speed limit that governs how fast and how large they can grow,” said Joseph Smidt of the Theoretical Design Division at Los Alam...

Garbage, nutrients and tiny animals are pushed around, suspended in the world’s oceans by waves invisible to the naked eye according to a new 3-D model developed by mathematicians at the University of Waterloo. David Deepwell, a graduate student, and Professor Marek Stastna in Waterloo’s Faculty of Math have created a 3-D simulation that showcases how materials such phytoplankton, contaminants, an...
