Big Data v. Cancer: Algorithm Identifies Genetic Changes across Cancers

December 15, 2014 4:00 pm | by Brown University | News | Comments

Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA).

Bird Tree of Life Reproduced using Gene Analysis, Supercomputing

December 15, 2014 1:57 pm | by Karlsruhe Institute of Technology | News | Comments

About 95 percent of the more than 10,000 bird species known only evolved upon the extinction of dinosaurs about 66 million years ago. According to computer analyses of the genetic data, today's diversity developed from a few species at a virtually explosive rate after 15 million years. Scientists designed the algorithms for the comprehensive analysis of the evolution of birds; a computing capacity of 300 processor-years was required.

Accessibility of Data and Application of Algorithms to Provide Insights in Predictive Analytics

December 15, 2014 11:56 am | by Michael Boruta, ACD/Labs | Blogs | Comments

Although there are a diverse range of applications for predictive analytics in R&D, two common basic requirements are data and insight. Data may be generated by running experiments/analyses, or re-applied from previous work when available. Insights come from application of knowledge — both explicitand tacit. There are a variety of roles for informatics in predictive analytics...

Sophisticated New Statistical Technique helps Map Species' Genetic Heritage

December 12, 2014 5:50 pm | by Liz Ahlberg, University of Illinois | News | Comments

Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo — the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.

New Theory could Yield More Reliable Communication Protocols

December 12, 2014 5:23 pm | by Larry Hardesty, MIT | News | Comments

Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver — say, a computer and a printer — are off by even a single bit relative to each other, communication between them breaks down entirely.

World's Oldest Computer, Ancient Greek Antikythera Mechanism, 100 Years Older than Previously Believed

December 9, 2014 2:10 pm | by University of Puget Sound | News | Comments

An ancient Greek astronomical puzzle has one more piece in place. The new evidence results from research by James Evans, professor of physics at University of Puget Sound, and Christián Carman, history of science professor at University of Quilmes, Argentina. The two researchers published a paper advancing our understanding of the Antikythera Mechanism, an ancient Greek mechanism that modeled the known universe of 2,000 years ago.

Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast.
