PSC to Host WVU Cluster

Oct. 10, 2017

A three-year National Science Foundation grant totaling nearly $1 million will let West Virginia University (WVU) develop its next-generation high-performance computing cluster to advance research in an array of fields, from drug delivery to genomics and astrophysics.

Nick Nystrom Appointed Interim Director of PSC

July 27, 2017

Nick Nystrom, senior director of research at the Pittsburgh Supercomputing Center (PSC), has been appointed interim director of the center. Nystrom succeeds Michael Levine and Ralph Roskies, who have been co-directors of PSC since its founding in 1985.

During the interim period, Nystrom will oversee PSC’s state-of-the-art research into high-performance computing, data analytics, science and communications, working closely with Levine and Roskies to ensure a smooth and seamless transition.

Zebrafish Study Reveals First Fine Structure of a Complete Vertebrate Brain

May 10, 2017

Zebrafish larva head in cross-section. Note this isn’t a single electron microscope image, but many thousands of slices seen on edge. The large black circle is the eye, the big darker gray shape at top the brain. You can also see the nose (black crescent at right), the ear (black crescent near center) and several vertebrae (center bottom).

 

Why It’s Important

Every thought, every feeling, every sensation—and every behavioral illness—ultimately depends on how our brains work. Despite decades of stunning advances in imaging the brain and measuring its activity, though, we still don’t understand how even a simple vertebrate brain works.

Enter the zebrafish larva. Small and transparent—yet able to swim freely and even hunt small prey—these baby fish have long been studied by researchers to understand how their tiny brains generate behaviors. David Hildebrand, working in

the laboratories of Florian Engert and Jeff Lichtman at Harvard University, took this work a step farther, creating electron microscopic images of the zebrafish brain cut
into tens of thousands of slices.

With the help of co-author PSC’s Art Wetzel, they led an international collaboration that used these images to reconstruct specific nerve cells that spanned nearly the entire larval zebrafish brain. The hope is that this kind of thorough “nano-scale” imaging will make it possible to

extract the brain’s complete “wiring diagram.” While this work has only just begun, it may eventually shed new light on past studies of zebrafish behavior—and point the way toward a better understanding of more complex brains, such as ours.

Modest Increase in Kids' Exercise May Yield Outsized Benefits

May 2, 2017

Getting just a few more American kids to run and play for 25 minutes three times a week could have outsized benefits in reducing obesity and save tens of billions of dollars, according to researchers at the Global Obesity Prevention Center at Johns Hopkins Bloomberg School of Public Health and the Pittsburgh Supercomputing Center at Carnegie Mellon University.

The investigators used their computer simulation tool, called VPOP—Virtual Population for Obesity Prevention—to calculate how increasing the number of elementary school children participating in physical activity would play out in health benefits. Increasing the percent of kids who get thrice-weekly exercise from the current 32 percent to just 50 percent, they found, would result in 340,000 fewer obese or overweight kids and save $21.9 billion in lifetime medical costs and lost wages.

Heat Stable Vaccines Could Save Lives, Money

April 26, 2017

Health care workers in low-income nations often have to deliver vaccines on rugged footpaths, via motorcycle or over river crossings. On top of this, vaccines need to be kept refrigerated or they may degrade and become useless, which can make getting vaccines to mothers and children that need them challenging.

That’s why researchers at Doctors Without Borders and the HERMES Logistics Team of the Global Obesity Prevention Center at the Johns Hopkins Bloomberg School of Public Health and the Pittsburgh Supercomputing Center at Carnegie Mellon University carried out the first computer simulation of the health and economic impacts of introducing heat-stable vaccines in India and in Benin and Niger in Africa. The simulation offered good news. Not only would vaccines that don’t require refrigeration help increase vaccination rates in these countries, the cost savings of decreased spoilage and improved health would more than cover the cost of making the vaccines stable, even at twice or three times the current cost per dose.
