The drive toward exascale computing, renewed emphasis on data-centric processing, energy efficiency concerns, and limitations of memory and I/O performance are all working to reshape HPC platforms, according to Intersect360 Research’s Top Six Predictions for HPC in 2015. The report cites many-core accelerators, flash storage, 3-D memory, integrated networking, and optical interconnects as just some of the technologies propelling future...
This 100x photo of living green algae in interference phase contrast received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken using a light microscope and Interphako contrast.
Liquid water is a requirement for life on Earth. But in other, much colder worlds, life might exist beyond the bounds of water-based chemistry. Taking a simultaneously imaginative and rigidly scientific view, chemical engineers and astronomers offer a template for life that could thrive in a harsh, cold world — specifically Titan, the giant moon of Saturn.
QR codes have been used to convey information about everything from cereals to cars and new homes. But researchers think the codes have a greater potential: protecting national security. Using advanced 3-D optical imaging and extremely low light photon counting encryption, researchers have taken the ordinary QR code and transformed it into a high-end cybersecurity application to protect the integrity of computer microchips.
We all like to know our watches keep the time well, but researchers are taking precision to an entirely new dimension. The group demonstrated two cryogenically cooled optical lattice clocks that can be synchronized to a tremendous one part in 2.0 x 10-18 — meaning that they would only go out of synch by a second in 16 billion years. This is nearly 1,000 times more precise than the current international standard cesium atomic clock.
Children don’t have to be told that “cat” and “cats” are variants of the same word — they pick it up just by listening. To a computer, though, they’re as different as, well, cats and dogs. Yet it’s computers that are assumed to be superior in detecting patterns and rules, not four-year-olds. Researchers are trying to, if not to solve that puzzle definitively, at least provide the tools to do so.
Astronomical images often look like works of art. This picture of one of our nearest neighboring galaxies, the Small Magellanic Cloud (SMC), is certainly no exception! The scene is actually a collaboration between two cosmic artists — ESA’s Herschel space observatory and NASA’s Spitzer space telescope.
ISC is introducing the Hans Meuer Award to honor the most outstanding research paper submitted to the ISC High Performance conference’s research paper committee. This annual award has been created in memory of the late Dr. Hans Meuer, general chair of the ISC conference from 1986 through 2014, and co-founder of the TOP500 project.
Leonard Nimoy, the actor known and loved by generations of Star Trek fans as the pointy-eared, purely logical science officer Mr. Spock, has died. Nimoy died Friday of end-stage chronic obstructive pulmonary disease at his Los Angeles home, with family at his side, said his son, Adam Nimoy. He was 83.
Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time. The discovery of this quasar, named SDSS J0100+2802, marks an important step in understanding how quasars, the most powerful objects in the universe, have evolved from the earliest epoch, only 900 million years after the Big Bang, which is thought to have happened 13.7 billion years ago.
From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can't be seen is the battle raging underfoot to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours into the sea — 130 billion tons per year for the past decade. That's the weight of more than 356,000 Empire State Buildings.
Pull on a piece of plastic at separate ends; it becomes thinner. So does a rubber band. One might assume tha,t when a force is applied along an axis, materials will always stretch and become thinner. Wrong. Thanks to their peculiar internal geometry, auxetic materials grow wider. After confounding scientists for decades, researchers are now developing mathematical models to explain the unusual behavior of these logic-defying materials
Three Austrians have replaced injured hands with bionic ones that they can control using nerves and muscles transplanted into their arms from their legs. The men are the first to undergo what doctors refer to as "bionic reconstruction," which includes a voluntary amputation, the transplantation of nerves and muscles and learning to use faint signals from them to command the hand.
The U.S. has elevated its appraisal of the cyber threat from Russia, the U.S. intelligence chief said February 26, 2015, as he delivered the annual assessment by intelligence agencies of the top dangers facing the country. "While I can't go into detail here, the Russian cyber threat is more severe than we had previously assessed," James Clapper, the director of national intelligence, told the Senate Armed Services Committee.
Researchers have developed a novel three-dimensional, multiscale and multicomponent model of the endothelial cell monolayer, the inner lining of the artery, to identify the cellular mechanisms involved in cardiovascular diseases. New research based on the model is able to identify the main cellular pathways involved in the initiation and progression of the disease.
