Pathogenic bacteria (red) live side-by-side with benign species (green) in a healthy mouth. Scientists are beginning to understand what causes bacterial communities to shift from health to diseases like periodontitis, diabetes, and Crohn's disease. Courte

Mouth Bacteria Can Change its Diet, Supercomputers Reveal

August 22, 2014 12:28 pm | by Jorge Salazar, TACC | News | Comments

Bacteria inside your mouth drastically change how they act when you're diseased. Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, diabetes and Crohn's disease. UT Austin researchers used shotgun metagenomic sequencing, a non-targeted way to study the all the genetic material of the bacterial communities. They analyzed the RNA collected with  Lonestar and Stampede.

Recently, the Harvard-Smithsonian Center for Astrophysics unveiled an unprecedented simulation of the universe’s development. Called the Illustris project, the simulation depicts more than 13 billion years of cosmic evolution across a cube of the universe that’s 350-million-light-years on each side. But why was it important to conduct such a simulation?

Visual Control of Big Data: Recomputing Visualizations without Aberrant Results

August 20, 2014 10:44 am | by Larry Hardesty, MIT | News | Comments

In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?

Brookhaven theoretical physicist Swagato Mukherjee explains that 'invisible' hadrons are like salt molecules floating around in the hot gas of hadrons, making other particles freeze out at a lower temperature than they would if the 'salt' wasn't there.

Invisible Particles Provide First Indirect Evidence of Strange Baryons

August 20, 2014 10:17 am | by Brookhaven National Laboratory | News | Comments

New supercomputing calculations provide the first evidence that particles predicted by the theory of quark-gluon interactions, but never before observed, are being produced in heavy-ion collisions at the Relativistic Heavy Ion Collider. These heavy strange baryons, containing at least one strange quark, still cannot be observed directly, but instead make their presence known by lowering the temperature at which other baryons "freeze out"

According to a group of journalists, a spy program known as "Hacienda" is being used by five western intelligence agencies to identify vulnerable servers across the world in order to control them and use them for their own purposes. However, scientists at the Technische Universität München have developed free software that can help prevent this kind of identification and, thus, the subsequent capture of systems.

Single Picture worth 1000 — and More — Images

August 15, 2014 12:38 pm | by Sarah Yang, UC Berkeley | News | Comments

A photo is worth a thousand words, but what if the image could also represent thousands of other images? New software seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can give users the photographic gist of a kid on Santa’s lap or housecats. It works by generating an image that literally averages the key features of the other photos.

With the promise of exascale supercomputers looming on the horizon, much of the roadmap is dotted with questions about hardware design and how to make these systems energy efficient enough so that centers can afford to run them. Often taking a back seat is an equally important question: will scientists be able to adapt their applications to take advantage of exascale once it arrives?
