Scientists Employing Supercomputers for Complex Visuals

Argonne_Supernova_Research.jpg

It may seem that the age of the supercomputer a la Cray-1 has long passed. But that’s not entirely true–we just don’t hear about them as often. For example, scientists at the U.S. Department of Energy’s Argonne National Laboratory are visualizing supernova, protein structures, and other complex phenomena using supercomputers.

The scientists there are using a technique called software-based parallel volume rendering, which interprets the billions of data points collected from MRIs, X-rays, or research simulations. They’re also working on equations that could search for sudden density changes–for example, separating bone from muscle data–in order to generate complex visualizations.

Using parallel computing, such as with Argonne’s Blue Gene/P supercomputer, scientists can create images using the computer’s 160,000 cores. (Try that on a Core i7.) The above image is a rendering of a supernova–specifically, the mechanisms behind a star’s violent collapse, with different colors and transparencies depicting different values of entropy.

OSU foresters swap tree fibers for rubber in fuel efficient tires

Leave it to a gaggle of brilliant wood science researchers at Oregon State University to figure out that we’ve been doing this whole “tire” thing wrong for generations now. While studying some uses of microcrystalline cellulose, which can be made easily from practically any type of plant fiber, these Earth-loving gurus discovered that said material could actually improve the efficiency of vehicle tires when used in place of silica. Granted, only about 12 percent of the silica — which is used as a reinforcing filler in the manufacture of rubber tires — was swapped out, but the resulting tires gripped just as well in wet weather while decreasing the rolling resistance during those dry summer months. Furthermore, tires constructed with these fibers could be made with less energy, though long-term durability studies are still needed to prove that this whole plan is viable for more than a few thousand miles.

Large Hadron Collider restart, end of the world pushed back to mid-November

Still undecided about what to do with those precious few months before the biggest doomsday since Y2K? Then you’re in luck, ’cause the much anticipated / feared restart of the Large Hadron Collider has now been delayed yet again, almost exactly a month after the last delay. This time it looks like a couple of vacuum leaks are the culprit, and CERN says that the collider is now unlikely to restart before mid-November, which just so happens to coincide with the peak of the Leonids meteor shower. Coincidence? Yes, yes it is.

More Leaks Found in Large Hadron Collider

LHC_CERN.jpg

Man, tremendous particle accelerators just can’t catch a break these days. Right as engineers finished repairing the helium leak that benched the Large Hadron Collider from doing much last year (aside from a successful early test), the team discovered two more vacuum leaks in another part of the machine.

In order for the leaks to be repaired, first engineers have to warm up the area, which is normally maintained at “ultracold temperatures,” according to Wired. The new delay will likely push the LHC’s projected restart sometime into November, after already being delayed twice recently.

Currently, the LHC is running about two and a half years behind schedule, according to the report.

Amateur Astronomer Calls in Jupiter Impact First

Jupiter_Impact_Wesley.jpgWith today’s tracking-enabled telescopes, digital cameras, and computer software, amateur astronomers are doing more useful work than ever before. Such was the case with Jupiter: it appears that a large object has just struck the surface of the planet. That’s similar to what happened in 1994 with comet Shoemaker-Levy–on the exact date of the 15th anniversary of that impact, in fact, not to mention the 40th anniversary of the Apollo landing.

Space.com reports that while NASA tracked the impact, the initial call came from Anthony Wesley of Murrumbateman, Australia, who told NASA he noticed a new dark “scar” suddenly appear on Jupiter early Friday between 6 a.m. and 12 p.m. EDT.

“I’d noticed a dark spot rotating into view in Jupiter’s south polar region and was starting to get curious,” Wesley wrote on his observation blog. “When first seen close to the limb (and in poor conditions) it was only a vaguely dark spot, I thought likely to be just a normal dark polar storm. However as it rotated further into view, and the conditions also improved, I suddenly realized that it wasn’t just dark, it was black in all channels, meaning it was truly a black spot.”

Wesley used a 14.5-inch reflector on an equatorial mount for his observations, as a separate New York Times article reports. NASA scientists are still studying the images to figure out what it was that hit Jupiter. (Image credit: Anthony Wesley)

Apollo Missions Driving Moon Lander Design at NASA

NASA_Orion_Crew_Exploration_Vehicle.jpg

The Apollo missions marked a turning point in human history. They changed the political climate of the day, made many tech advances possible, and inspired future scientists and astronomers the world over. But it turns out they’re also having a far more practical effect: acting as a guiding light for future lunar missions.

NASA’s next-generation Orion spaceship–scheduled for first launch in 2015–may look a lot like the Apollo craft in use 40 years ago. But as Space.com reports, the similarities are often just skin deep–and also draw from the Shuttle program as well. “The computing power of modern electronics just dwarfs what [Apollo engineers] had available,” Jim Geffre, a NASA engineer working on Orion, said in the article. “That allows us to do a lot more and build more automation into the spacecraft. More performance that uses less power and less space allows us to build in redundancy that Apollo didn’t have.”

The Orion is also about four feet larger in diameter–16.5 feet, to the Apollo craft’s 12.8 feet–which will enable four astronauts to travel to the moon instead of three, let all four descend to the surface (instead of just two), and allow for missions that run several weeks long.

Universal mirrors: more useful, less fun than carnival mirrors

You know those invisibility cloaks scientists have been struggling to master for decades? This here is said cloak’s perfect opposite, and it’s bending our minds in ways you can hardly fathom. Ulf Leonhardt, a professor at the University of St. Andrews, has worked with a brilliant team of scientists in order to construct what he calls a universal mirror, or if we’re being proper, an omnidirectional retroreflector. Unlike conventional mirrors which simply reflect objects at 90 degrees, this concoction reflects objects back at any angle. In other words, a device such as this would make aircraft, boats and satellites entirely easier to track with radar, but it’ll have to mature quite a bit before it’s ready for that kind of action. The current build is just a single centimeter high and ten centimeters in diameter, and as with invisibility cloaks, the main ingredient here is metamaterials that we won’t pretend to fully understand. Just one word of caution, boffins — don’t let Geek Squad get ahold of this stuff.

The plot thickens: robot teachers to brainwash your children’s children

Are you ready for this? Can you stomach the truth? If things continue spiraling madly out of control as they are right now, there’s at least a modicum of a chance that your children or grandchildren will greet a lifelike robot when sashaying in for the first day of kindergarten. Horrifying, we know. A new research effort published in this month’s Science outlines new ways in which humanoids could actually be used to instruct our little ones. At the core of the project is imitation; humans, especially young ones, learn a multitude of mannerisms and such by simply watching others. Thus, it stands to reason that robots are “well-suited to imitate us, learn from us, socialize with us and eventually teach us.” Already, these social bots are being used on an experimental basis to teach various skills to preschool children, “including the names of colors, new vocabulary words and simple songs.” Just think — in 2071, those harmless lessons will morph into studies of subterfuge, insurrection and rapacity.

eSpace Funding Space Entrepreneurs

eSpace_Flight.jpg

The commercial push for spaceflight continues: eSpace: the Center for Space Entrepreneurship, a non-profit, aerospace business investment firm supported by the Air Force Research Lab, has put up funding for three companies for space business development as part of its eSpace Incubator program.

The three companies are Zybek Advanced Products, which is building synthetic moon rock for NASA to test lander and rover performance; Space Awareness Services, which tracks satellites, space debris, and other orbital objects; and Net-Centric Design Professionals, a cyber-security firm working on satellite imaging and network design.

Good stuff all around, guys; just let us know when we can all hitch rides on spaceships and we’ll be psyched.

Restored Video Shows Apollo 11 Moonwalk

NASA_Apollo_11_Video.jpg

NASA released Thursday newly restored video of the Apollo 11 mission from July 20th, 1969, including video showing the moonwalk more clearly than what has been seen before. It’s part of the 40th anniversary commemoration of astronauts landing on the moon for the first time.

The initial release shows 15 key moments from the mission. The video material came from a variety of sources and was assembled by a team of Apollo-era NASA engineers.

“The restoration is ongoing and may produce even better video,” said Richard Nafzger, an engineer at NASA’s Goddard Space Flight Center that oversaw TV processing during Apollo 11, in a statement. “The restoration project is scheduled to be completed in September and will provide the public, future historians, and the National Archives with the highest quality video of this historic event.”

The new videos are definitely clearer. Unfortunately, an opportunity to make them sharper still was lost, it turns out. NASA concluded after an exhaustive three year search that the original tapes–not the degraded broadcast versions–were most likely erased and reused accidentally sometime in the early 1980s for satellite missions, as NPR reports. But we’ll take whatever we can get, of course.

With that, we’d like to turn it over to you, our readers. What are your memories of the Apollo 11 mission? Let us know in the Comments section below.
