Indiana University Joins International Grid Computing Organization

Indiana University is now a member of the Distributed Organization for Scientific and Academic Research (DOSAR), a grass-roots entity focused on international grid computing research and education. This new partnership will allow IU tech experts to continue to participate in DOSAR outreach activities that target sub-Saharan universities. One such activity is the African Grid School, held in conjunction with DOSAR’s African School of Fundamental Physics and its Application. Held every other year, the event attracts nearly 60 physics graduate and postdoctoral students who want to learn ne...

UCSD Research Scientists to Use Network Much Faster Than Interne

The New York Times

The National Science Foundation has provided a five-year, $5-million grant to deploy a series of ultra-high-speed fiber-optic cables to link West Coast university laboratories and supercomputer centers into the Pacific Research Platform. The network is designed to keep up with the acceleration of data compilation in disciplines such as physics, astronomy, and genetics, moving torrents of data at speeds of 10 Gbps to 100 Gbps among participating labs and institutions. The network will not have a direct Internet connection, and Larry Smarr at the Univer...

Beyond Just 'Big' Data

IEEE Spectrum

As new big data technologies advance and the challenges of extracting meaning from these massive data sets shift, it seems likely computer scientists will need an entirely new vocabulary to define these various trends. For example, big data enthusiasts sometimes categorize storage units as "brontobytes," each of which adds up to 1,000 trillion terabytes. A unit of 1,000 brontobytes is called a "geobyte." Accompanying the new lexicon of big data storage units are new terms for data professionals, which include specialists in building data models, or data ar...

Methane Enshrouds Nearby Jupiter-Like Exoplanet

The Gemini Planet Imager has discovered and photographed its first planet, a methane-enshrouded gas giant much like Jupiter that may hold the key to understanding how large planets form in the swirling accretion disks around stars. The GPI instrument, which is mounted on the 8-meter Gemini South telescope in Chile, is the size of a small car and was designed, built and optimized for imaging and analyzing the atmospheres of faint Jupiter-like planets next to bright stars, thanks to a device that masks the star’s glare. In December 2104, GPI began searching hundreds of nearby young stars,...

UChicago Study: Parents’ Math Anxiety Can Undermine Children’s Math Achievement

If the thought of a math test makes you break out in a cold sweat, Mom or Dad may be partly to blame, according to new research from the University of Chicago.  A team of researchers led by UChicago psychologists Sian Beilock and Susan Levine found that children of math-anxious parents learned less math over the school year and were more likely to be math-anxious themselves—but only when these parents provided frequent help on the child’s math homework. The new study, “Intergenerational Effects of Parents’ Math Anxiety on Children’s Math Achievement and Anxiety,” appears ...

Rice University Algorithm Clarifies ‘Big Data’ Clusters

Rice University scientists have developed a big data technique that could have a significant impact on health care. The Rice lab of bioengineer Amina Qutub designed an algorithm called “progeny clustering” that is being used in a hospital study to identify which treatments should be given to children with leukemia. Clustering is important for its ability to reveal information in complex sets of data like medical records. The technique is used in bioinformatics — a topic of interest to Rice scientists who work closely with fellow Texas Medical Center institutions. “Doctors who desi...
