Simulating Matter Distribution Across The CosmosJoe Insley and the HACC team, Argonne National Laboratory.
Sometime next month, the world’s third-fastest supercomputer —known as Mira—will complete tests of its new upgraded software and begin running the largest cosmological simulations ever performed at Argonne National Laboratory. These simulations are massive, taking in huge amounts of data from the latest generation of high-fidelity sky surveys and crunching it into models of the universe that are larger, higher-resolution, and more statistically accurate than any that have come before. When it’s done, scientists should have some amazing high-quality visualizations of the so-called “cosmic web” that connects the universe as we understand it. And they’ll have the best statistical models of the cosmos that cosmologists have ever seen.
A cooperative agreement between MIT and DARPA worth up to $26.3 million will be used to establish a new program titled “Barrier-Immune-Organ: MIcrophysiology, Microenvironment Engineered TIssue Construct Systems” (BIO-MIMETICS) at MIT, in collaboration with researchers at the Charles Stark Draper Laboratory, MatTek Corp. and Zyoxel Ltd.
Fortunately, there are at least half a dozen projects dedicated to building brain models using specialized analog circuits that can model brain activity as fast as or even faster than it really occurs, and they consume a fraction of the power.
Stanford University scientists reported on Thursday they had made the first full computer model of an organism, another breakthrough in a field that’s both raising hopes of fighting disease and stoking fears of biological engineering.
The team, led by Markus W. Covert, a professor of bioengineering at Stanford, made the model using Mycoplasma genitalium, a standard target for such work because of its status as the world’s smallest free-living bacterium.
The latest computer model of the cosmos involves 400 billion particles in a box about two thirds of the volume of the universe
… Today, Juhan Kim at the Korea Institute for Advanced Study in Seoul, and a few pals, show just how far this technique has come. These guys have carried out the largest simulation of the universe ever undertaken, consisting of 374 billion particles in a box some 10 gigaparsecs across. That’s roughly equivalent to about two thirds the size of the observable universe.
This took some 20 days of computing time on the Tachyonii supercomputer in Korea, the 26th fastest in the world in the last set of rankings.
It seems abundantly clear that Apple, which recently snapped up its third mapping company, is planning a rival to Google Maps for its iOS devices.
Ever since the iPhone first came on the scene in 2007, Apple has been dependent on Google Maps. But there have been hints that Apple, at least since 2009, has been planning a rival service. In that year, it bought a mapping company called Placebase; last year, it scooped up a 3-D mapping company called Poly9. This week, 9to5Mac confirms that Apple has now purchased a third mapping company, C3 Technologies, which mysteriously shut down in August following its acquisition from a then-unnamed buyer.
After spending their childhood playing online games, students at Choate Rosemary Hall will soon be able to live inside one. When the academic year begins next autumn, the tony Connecticut prep school will open the Kohler Environmental Center, a living-learning facility where teams of students will compete with one another to see who can live most energy efficiently. Think of it as a sort of SimCity meets Survivor: Wallingford.
Combing through the massive amounts of data regarding this year’s massive 9.0 earthquake off the coast of Japan, researchers have found mountains of useful information. Visualizing it all usefully has proven tricky, but some new techniques coming out of the University of Alaska at Fairbanks show promise.
The year two film of director Noah Hutton’s 10-year documentary-in-the-making on the progress of the ambitious Blue Brain Project is now online and well-worth watching.
The Blue Brain Project is often touted as aiming to ‘simulate the human brain’ but a more accurate description would probably be that it aims to create a simulation of cortical column circuits from the neuromolecular level up to the point where it’s as equally as complex as the human brain.
