The big-headed ant (Pheidole megacephala) is considered one of the world’s worst invasive ant species. Their giant, muscle-bound noggins power their biting parts, the mandibles, which they use to attack other ants and cut up prey. In a new study, researchers report that big-headed ant colonies produce larger soldiers when they encounter other ants that know how to fight back.
Scientists are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays — the most energetic particles in the Universe.
Error-correcting codes are one of the glories of the information age: They’re what guarantee the flawless transmission of digital information over the airwaves or through copper wire, even in the presence of the corrupting influences that engineers call “noise.”
Yale University West Campus will open the doors to a new microscopy Center of Excellence made possible through a collaboration with Leica Microsystems. Housed in a newly created core facility, the Leica Center of Excellence at Yale West Campus will provide scientists with access to cutting-edge imaging tools to resolve sub-cellular structures and forward scientific discoveries.
The GS7KTM appliance is a scale-out parallel file system solution complete with enterprise-class features, NAS access and Cloud tiering capabilities. The system includes fully integrated enterprise data management and protection capabilities, in a simple, all-in-one, scale-out appliance.
A few days after autumn showed up on the calendar in the Northern Hemisphere, it showed up on the landscape of North America. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this view of fall colors around the Great Lakes on Sept. 26, 2014.
Researchers have brought ultra-fast, nano-scale data storage within striking reach, using technology that mimics the human brain. They have built a novel nano-structure that offers a new platform for the development of highly stable and reliable nanoscale memory devices.
In popular culture, mathematics is often deemed inaccessible or esoteric. Yet in the modern world, it plays an ever more important role in our daily lives and a decisive role in the discovery and development of new ideas — often behind the scenes.
Computer modelling of the human eye, the brain of a rat and a robot could revolutionize advances in neuroscience and new technology. A new study uses new computer algorithms to enable robots to navigate intelligently, unrestricted by high-density buildings or tunnels.
On a July night this summer, a 5,200-pound balloon gondola hangs from a crane and moves toward the open doors of a building at the Johns Hopkins University Applied Physics Lab in Laurel, Md. The telescopes and instruments carried by the gondola, which are part of NASA’s Balloon Observation Platform for Planetary Science (BOPPS), are calibrated by taking a long look at the stars and other objects in the sky.
Engineers have completed the first comprehensive numerical simulation of skeletal muscle tissue using a method that uses the pixels in an image as data points for the computer simulation — a method known as mesh-free simulation.
The Cray XC40 supercomputer and CS 400 cluster supercomputer feature the new Intel Xeon processor E5-2600 v3 product family, formerly code named “Haswell." The supercomputer is available with the new DataWarp technology, which is an applications I/O accelerator that addresses the growing performance gap between compute resource and disk-based storage.
Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule – one with a branched structure – contained within a giant gas cloud in interstellar space. Like finding a molecular needle in a cosmic haystack, astronomers have detected radio waves emitted by isopropyl cyanide. The discovery suggests that the complex molecules needed for life may have their origins in interstellar space.
Mathematicians have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and trade of mathematics, the researchers hope this new formulation might ultimately lead to mathematical models that better reflect the inherent uncertainties of the natural world.
Researchers are developing a robotic fabric that moves and contracts and is embedded with sensors, an approach that could bring "active clothing" and a new class of "soft" robots.
