Perspectives | The growing importance of data curation

August 29, 2011

Excerpt:

With the world awash in information, curating all the scientifically relevant bits and bytes is an important task, especially given digital data’s increasing importance as the raw materials for new scientific discoveries, an expert in information science at the University of Illinois says. Carole L. Palmer, a professor of library and information science, says that data curation — the active and ongoing management of data through their lifecycle of interest to science — is now understood to be an important part of supporting and advancing research….The Center for Informatics Research in Science and Scholarship at Illinois will receive about $2.9 million as a partner on the Data Conservancy project, a $20 million initiative led by Sayeed Choudhury at the Johns Hopkins University Sheridan Libraries. The five-year award, one of the first two in the National Science Foundation’s DataNet program, will fund developing infrastructure for the management of the ever-increasing amounts of digital research data.

News | Kepler satellite and citizen planet hunters

April 15, 2011

Excerpt: While computers are terrific at high-volume data-processing, nothing beats the human eye for pattern-recognition – which is why a project dreamed up by Yale University astronomer Debra Fischer, a veteran planet hunter and Kepler project scientist, has turned out to be so extraordinarily useful. Called Planethunters.org, it lets ordinary folks with no scientific training at all help find planets the Kepler software has missed. It works so well that in just a few short months of operation, the more than 22,000 visitors to the website have found nearly 50 potential planets, which are being sent on to Kepler headquarters at the NASA Ames Research Center in California for followup.

News | Pulsar Discovery by Global Volunteer Computing

September 10, 2010

From Knispel et al., 2010. Science 329 p:1305

Appearing in this week’s issue of Science is the official published result by Knispel et al. describing how the grid computing framework, Einstein@Home, was used to discover a strange new Pulsar spinning unusually fast for a pulsar without a binary companion.   Based on it’s more famous big brother, SETI@home, the Einstein@Home project transmits packets of data to individual home computers that then process and analyze the data during idle cycles.   The statistics involved in such an effort are impressive.  According to the article, more than 250,000 volunteers have contributed, with 100,000 separate computers downloading analysis jobs each week, resulting in the equivalent of a 0.25 petaflop/second computer (250 trillion floating point operations per second!). This is comparable to roughly the 25th fastest supercomputer on the planet according the widely referenced Top 500 Supercomputer Sites.    Designated J2007+2722, the pulsar is rotating at nearly 41 times per second.   The authors describe it as “likely the fastest-spinning disrupted recycled pulsar yet found” whose unique characteristics “contributes to our understanding of pulsar evolution.”    They conclude:

This result demonstrates the capability of “consumer” computational power for realizing discoveries in astronomy and other data-driven science.
