 SXSW 2015: ScaaS & Other Lies: Hacking Big Data on the Web | File Type: audio/mpeg | Duration: 10:10

John Fonner is part of the Life Sciences Computing Group at TACC, and Rion Dooley manages the web and cloud services group plus he leads the Agave API project. Fonner and Dooley present a hands-on four-hour workshop for South by Southwest Interactive on Tuesday, March 17th. It's called Science as a Service and other Lies: Hacking Big Data on the Web. In the podcast they discuss science-as-a-service. Rion Dooley: When we talk about science as a service, what we're really talking about is the ability to think about your science and interact with your data and with your experiments in a way that is thinking in terms of the problems you're trying to solve rather than the machines you're trying to solve them on. John Fonner: The domain field is a patchwork of individual codes out there that have very specific assumptions about the type of system that you're running them on. The types of algorithms might have very different hardware requirements. And the data volumes now for a lot of the next-generation sequencing questions are just huge. We want to talk about the tools that we have and the way that we've been tackling this problem and really taking it from a place that is inaccessible to most biologists and only accessible to the most technically savy scientists, and putting it in a place where pretty much anyone can have access to it.

  SXSW 2015: Science + Tech Meet Up: Scientists and Geeks Unite | File Type: audio/mpeg | Duration: 4:49

Maytal Dahan is a research engineer and science associate at the Texas Advanced Computing Center. She presents a meet up for South by Southwest Interactive on Saturday, March 14. It's called Science and Tech Meet Up: Scientists and Geeks Unite!. In the podcast Dahan talks about some interesting intersections where science meets software development, and she predicts the next big thing at SXSW -- science! Maytal Dahan: It'd be really great if we could get developers of all kinds – user interface, web, application developers – who are interested to learn how science impacts the world we live in today, and how to engage and possibly contribute their skills to science projects…A developer at a start-up doesn't always get to meet a scientist creating an API for their application.

 Supercomputers Help Solve Puzzle-Like Bond for Biofuels | File Type: audio/mpeg | Duration: 9:39

Host Jorge Salazar reports from the Texas Advanced Computing Center an interview with Klaus Schulten, professor of Physics at the University of Illinois at Urbana-Champaign.One of life's strongest bonds has been discovered by a science team doing research on biofuels with the help of supercomputers. The biomolecular interaction binds at about half the strength of a chemical covalent bond the pieces of a finger-like system of proteins called cellulosomes used by bacteria in cow stomachs to digest plants. The researchers published their results in the journal Nature Communications in December of 2014. Their find could boost efforts to develop catalysts for biofuel production from non-food waste plants.

 Supercomputing the Evolution of a Model Flower | File Type: audio/mpeg | Duration: 15:57

Scientists have used supercomputers to find what they say is the best evidence yet that a plant's genes  sensitive to cold and drought will help it adapt to changes in its environment. What they studied in plants was gene expression, instructions coded in DNA that regulate how many proteins it makes. Gene expression gives rise to traits such as tolerance of cold or drought, and it can evolve through natural selection to help a plant cope with environments out of its comfort zone.  The results of the computational biology study were published in the journal Molecular Biology and Evolution in September of 2014. In it scientists studied the flowering mustard weed Arabidopsis thaliana, known as a model plant in part because it has one of the smallest genomes, which was completely sequenced in 2000. The science team first took Arabidopsis genes found in the lab from a prior study that respond to cold and drought. They then compared those to reference genomic data from over a thousand strains collected throughout Europe and Asia.  Finding associations was like finding a needle in a haystack, and to do that they enlisted the help of the iPlant collaborative and they used the Ranger and Lonestar supercomputers of the Texas Advanced Computing Center.The study was co-authored by Thomas Juenger, a faculty member in the Department of Integrative Biology of the University of Texas at Austin.

 Interstellar Mystery Solved by Supercomputer Simulations | File Type: audio/mpeg | Duration: 23:31

Astrophysicists have been puzzled by their observations since the 1970s that only a small fraction of matter in the cloud becomes a star and part of a galaxy. They found a lot less of the universe's mass than expected in the middle of galaxies. Things changed when a multi-university collaboration produced a set of new supercomputer models of galaxies called FIRE, The Feedback in Realistic Environments. FIRE simulations ran on the Stampede supercomputer at TACC, an XSEDE resource funded by the National Science Foundation. Theoretical astrophysicist Philip Hopkins of CalTech led a 2014 study of initial results that found that star activity - like supernova explosions or even just starlight - plays a big part in the formation of other stars and the growth of galaxies. Philip Hopkins spoke more about galaxies on FIRE.
