Genomics Among the Biggest of Big Data, Illinois Experts Say

Each cell in the body contains a whole genome, yet the data packed into a few DNA molecules could fill a hard drive. As more people have their DNA sequenced, that data will require massive computational and storage capabilities beyond anything previously anticipated, says a new assessment from computational biologists and computer scientists at the University of Illinois and Cold Spring Harbor Laboratory. The team of experts compared data needs of genomics with three of the biggest players in big data: astronomy, Twitter and YouTube. They projected growth in each area through the year 202...

We're Not Alone – But the Universe May Be Less Crowded than We Think: Michigan State University Stude

There may be far fewer galaxies further out in the universe then might be expected, according to a new study led by Michigan State University. Over the years, the Hubble Space Telescope has allowed astronomers to look deep into the universe. The long view stirred theories of untold thousands of distant, faint galaxies. The new research, appearing in the current issue of the Astrophysical Journal Letters, however, offers a theory that reduces the estimated number of the most distant galaxies by 10 to 100 times. “Our work suggests that there are far fewer faint galaxies than we once previ...

Computational Fact-Checking at Indiana University

Network scientists at Indiana University have developed a new computational method that can leverage any body of knowledge to aid in the complex human task of fact-checking. In the first use of this method, IU scientists created a simple computational fact-checker that assigns “truth scores” to statements concerning history, geography and entertainment, as well as random statements drawn from the text of Wikipedia, the well-known online encyclopedia. In multiple experiments, the automated system consistently matched the assessment of human fact-checkers in terms of their certitude abo...

This problem challenges you to create a hybrid MPI+OpenMP model of princes, princesses, frogs, and witches.



The model in this problem is based on Shodor's “Kiss a Frog” model ( You may find it helpful to reference that model as you solve the problem.


This challenge problem is also similar to seven previous...

Extreme Weather in a Changing Climate: NCAR Asking the Right Questions

When a deadly heat wave lingers for an especially long time; when a hurricane makes landfall with particular ferocity; or when droughts, winter storms or cold snaps break records, the public is increasingly interested in knowing if human-induced climate change played a role. Attributing individual extreme weather events to a warming climate is difficult work. Even so, scientists have been making an effort in recent years to determine when a connection can be detected. In a new "Perspective" piece published in Nature Climate Change, scientists at the National Center for Atmospheric Researc...

Federal Focus on Big Data

SDSC’s PACE program comes as the administration’s Office of Science and Technology Policy (OSTP) last month announced $200 million in funding for new investments in big data research and development projects with the announcement of its Big Data initiative. With support of the National Science Foundation (NSF), and to achieve their goals of leveraging data-intensive tools to aid in the country’s research, defense and economic programs, the White House and the OSTP are bringing together six federal agencies or departments, including Homeland Security, the Department of Defen...

The Ohio Supercomputer Center Statewide Users Group (SUG) Meeting Provides Opportunity to Explain Research

Research projects featuring a wide range of scientific interests, such as electron microscopy, pesticides and polymers, were featured at the first-ever poster session and flash talk competition at the Ohio Supercomputer Center (OSC) June 4. The competition was held during the semi-annual meeting of the Statewide Users Group. SUG is a volunteer group comprised of the scientists and engineers who provide OSC’s executive director with program and policy advice and direction “to ensure a productive environment for research.” SUG was instituted in 1986, a year prior to the creat...

The Mozilla Fellowship for Science Available to Graduate Students

Application Deadline – August 14, 2015

The Mozilla Fellowships for Science present a unique opportunity for researchers who want to influence the future of open science and data sharing within their communities. We're looking for researchers with a passion for open source and data sharing, already working to shift research practice to be more collaborative, iterative and open. Fellows will spend 10 months starting September 2015 as community catalysts at their institutions, mentoring the next generation of open data practitioners and researchers and buildin...
