Deconstructing the Hummingbird’s Hover

Sep 2, 2014 |

Ever wonder how a hummingbird is able to hover in mid-air, appearing for a moment to defy the laws of gravity? You’re not alone. Vanderbilt University mechanical engineer Haoxiang Luo accessed the XSEDE’s Lonestar supercomputer to run 3D simulations of a hummingbird flight in an attempt to deconstruct its mysterious powers. Science Writer Jorge Salazar details Luo’s Read more…

Supercomputing Facilitates Breakthrough Cancer Treatment

Aug 25, 2014 |

MD Anderson Cancer Center researchers are relying on a powerful supercomputer to develop a dosing protocol for an MRI-guided radiation therapy for cancer care, called MRI-linac. The Lonestar system at the Texas Advanced Computing Center (TACC) is helping researchers fine-tune the radiation dosing mechanism so that just the right amount of radiation is delivered to the Read more…

Simulations Link Common Brain Disorders

Jul 28, 2014 |

When a coalition of leading researchers from the US and the EU wanted to study brain disorders that involve disturbances of dopaminergic signaling, they turned to the powerful supercomputing resources of the Texas Advanced Computing Center. Using the Extreme Science and Engineering Discovery Environment (XSEDE) cyberinfrastructure and TACC’s Stampede supercomputer, the research team uncovered a link Read more…

Simulations Reveal More About Oldest Known Star

Jul 23, 2014 |

Thanks to the power of supercomputing, scientists from the Universities of Göttingen and Copenhagen now have a better understanding of one of the most ancient stars in the universe. The results of their study were published in the July 21st edition of Astrophysical Journal Letters. The group used high-resolution computer simulations to model the formation of the oldest Read more…

Supercomputers Boost Jet Engine Design

Jun 11, 2014 |

The United States is home to many of the world’s top supercomputers, powerful machines that enable a wide-range of research efforts, from exploring the outer reaches of the universe to enabling faster, quieter and more efficient jet engines. As revealed in a recent report, a group of GE engineers are working with researchers from Arizona Read more…

Mega-Simulations Resolve Starburst Puzzle

May 19, 2014 |

Astrophysicists at the CEA (the French Alternative Energies and Atomic Energy Commission) and CNRS (the French National Center for Scientific Research) have achieved a major breakthrough. Thanks to a set of highly precise supercomputer simulations, the scientists have a much keener understanding of the turbulence that is generated when two galaxies collide. The study used Read more…

Graphene Faces Real-World Limitations

May 5, 2014 |

Graphene is a one-atom-thick layer of carbon that has been hailed as a potential silicon replacement capable of extending the exponential computing advances that modern society has come to depend on. Despite the material’s profile of being strong, flexible, light-weight and a good conductor, there are still a number of challenges that must addressed before Read more…

Virtual Earthquakes Predict Real Risk

Jan 28, 2014 |

Scientists at Stanford devised a “virtual earthquake” technique capable of predicting the effects of a major quake occurring along the southern San Andreas Fault. The remarkable thing about the new technique is that it relies on weak vibrations generated by the Earth’s oceans to create these ‘virtual earthquakes’ in order to forecast resultant ground movement Read more…

Big Rig Redesign Still Going Strong

Aug 26, 2013 |

In 2011, South Carolina-based BMI Corp. worked with researchers at Oak Ridge National Laboratory (ORNL) to develop a technology that improves the aerodynamics of long haul tractor trailers, thereby boosting fuel efficiency. Two years later, the company and the partnership are still going strong.

Sequoia Hits Warp Speed

May 6, 2013 |

Chalk up another win for Sequoia and high-performance computing. The IBM Blue Gene breaks two more records.
