Science On Repeat - Computational Reproducibility

Supersized Science ·

2019/04/19

Trust, but verify. The well-known proverb speaks to the heart of the scientific method, which builds on the results of others but requires that data be collected in a way that can be repeated with the same results. Beyond just recreating the conditions of a physical experiment, the computational analysis of data also factors into scientific reproducibility. Joining host Jorge Salazar on the podcast are Dan Stanzione, Executive Director of the Texas Advanced Computing Center and Associate

Supercomputers Help Supercharge Protein Assembly

2019/04/16

Using supercomputers, scientists are just starting to design proteins that self-assemble to combine and resemble life-giving molecules like hemoglobin. Hemoglobin molecules in red blood cells transport oxygen by changing their shape. Four copies of the same protein in hemoglobin open and close like flower petals, structurally coupled to respond to each other. A science team from the University of Texas at Austin and the University of Michigan made a flower-like structured molecule by supercharging

Award-Winning Visualization Dives Into Arctic Ocean

2019/03/25

Change is in the air, and water, of the Arctic Ocean. Scientists are keeping an eye out on shrinking sea ice, five million square miles of floating ice surrounding the North Pole. It bounces sunlight back to space, which keeps polar regions cool and helps moderate global climate. An award-winning simulation shows the complex changes in circulation happening at one of Earth’s most remote and inaccessible places, the Arctic Ocean. The Texas Advanced Computing Center (TACC) shared an award with UT

A New Way to See Stress — Using Supercomputers

Supersized Science ·

2019/03/25

It’s easy to take a lot for granted. Scientists do this when they study stress, the force per unit area on an object. Scientists handle stress mathematically by assuming it to have symmetry. That means the components of stress are identical if you transform the stressed object with something like a turn or a flip. Supercomputer simulations show that at the atomic level, material stress doesn’t behave symmetrically. That’s according to a study published September of 2018 in the Proceedings of the

Any truck operator knows that hydraulics do the heavy lifting. Water does the work because it’s nearly incompressible at normal scales. But things behave strangely in nanotechnology, the control of materials at the scale of atoms and molecules. Using supercomputers, scientists found a surprising amount of water compression at the nanoscale. These findings could help advance medical diagnostics through creation of nanoscale systems that detect, identify, and sort biomolecules. The unexpected effect

The National Science Foundation announced on August 29, 2018 an award of 60 million dollars to the Texas Advanced Computing Center (TACC) at UT Austin for the acquisition and deployment of a new supercomputer that will be the fastest at any U.S. university and among the most powerful in the world. The new system is called Frontera , Spanish for "frontier," and it will begin operations in 2019.

Scientists have used supercomputers to engineer an enzyme that breaks down plastic. It’s called polyethylene terephthalate, or PET, and it’s used to make things like carpets and bottles for soda and water. This plastic pollutes the soil and the oceans. The scientists say it’s a first step toward recycling PET and other plastics into commercially valuable materials at industrial scale. They published their results March of 2018 in the Proceedings of the National Academy of Sciences. The researchers

What makes kevlar stop a bullet, at the atomic level? The properties of materials emerge from their molecular or atomic structure. Yet many details between the micro and the macro remain a mystery to science. Scientists are actively researching the rational design of targeted supramolecular architectures, with the goal of engineering their structural dynamics and their response to environmental cues. A team of chemists at the University of California, San Diego has now designed a two-dimensional

Scientists have made the best computational modeling yet of mantle plumes. These are hypothesized, mushroom-shaped upwellings of hot rock from deep in the Earth that reach more than a thousand kilometers down. The scientists modeled mantle plumes on the Stampede supercomputer of the Texas Advanced Computing Center through an allocation on XSEDE, the eXtreme Science and Engineering Discovery Environment funded by the National Science Foundation. And through XSEDE they also took advantage of Science
