Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast.

Researchers have discovered an invisible shield some 7,200 miles above Earth that blocks so-called killer electrons, which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms. The barrier to the particle motion was discovered in the Van Allen radiation belts, two doughnut-shaped rings above Earth filled with high-energy electrons and...
Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But, while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined.
Following years of tests in physics laboratories, the first quantum technologies are slowly emerging into wider applications. One example is quantum cryptography — an encryption method providing an almost full guarantee of secure data transmission, currently being introduced by military forces and banking institutions.
NAG Compiler 6.0 accurately follows Fortran and OpenMP programming language standards, supporting OpenMP 3.1 and Fortran 2008, 2003 and 95. Because the code is correct; applications that are developed with and checked by the NAG Compiler are ready to be run on a wide range of current and future computer processors.
This 40X photo shows autofluorescence of the cuticle of a microscopic marine waterbear, or tardigrade (Actinarctus doryphorus). It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using confocal microscopy.
After 48-hours of real-time, spirited competition, two triumphant winners emerged in this year’s SC14 Student Cluster Competition. The annual challenge is designed to introduce the next generation of students to the high-performance computing community. Over the last few years, it has drawn teams of undergraduate and/or high school students from around the world, including Australia, Canada, China, Costa Rica, Germany, Russia and Taiwan.
At a White House ceremony on November 20, 2014, President Obama presented the National Medal of Science and National Medal of Technology and Innovation to individuals who have made outstanding contributions to science and engineering. The awards are the nation's highest honors for achievement and leadership in advancing the fields of science and technology.
ClusterStor Engineered Solution for Lustre offers improved metadata performance and scalability by implementing the Distributed Namespace (DNE) features in the Lustre 2.5 parallel file system. In addition to the Base Metadata Management Server capability, ClusterStor users have the option to add up to 16 Lustre Distributed Namespace metadata servers per single file system, providing client metadata performance improvement of up to 700 percent.
Conventional treatment seeks to eradicate cancer cells by drugs and therapy delivered from outside the cell, which may also affect — and potentially harm — nearby normal cells. In contrast, a research team has developed several novel designs for iron-oxide based nanoparticles that detect, diagnose and destroy cancer cells using photo-thermal therapy, using nanoparticles to focus light-induced heat energy only within the tumor
Tens of thousands of researchers currently harness the power of supercomputers to solve research problems that cannot be answered in the lab. However, this represents only a fraction of the potential users of such resources. As high performance computing becomes central to the work and progress of researchers in all fields, from genomics and ecology to medicine and education, new kinds of computing resources are required.
This 100X photo shows a polished section of a fossilized permocarbonian horsetail, a family of vascular plants that reproduces by spores. It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken by using reflected light.
The fundamental research in computing and engineering that enabled robotics to develop in the U.S. has been supported by the National Science Foundation (NSF) since its inception. Yet despite these early investments in sensors, machine movement and computer vision, it wasn't until 1972 that the first grant with "robot" in the title was funded.
Wireless data transmission largely takes place via WLAN networks, such as WiFi. However, these networks are currently limited to high frequency ranges at 2 GHz and above and, hence, have a limited range. The authors of the study propose to extend the frequencies for free communication to include lower ranges and even increased transmission power.
The PowerEdge C4130 is an accelerator-optimized, GPU-dense, HPC-focused rack server purpose-built to accelerate the most demanding HPC workloads. It is the only Intel Xeon E5-2600v3 1U server to offer up to four GPUs/accelerators and can achieve over 7.2 Teraflops on a single 1U server, with a performance/watt ratio of up to 4.17 Gigaflops per watt.
This 250X photo shows a cross-section of a young juniper shoot. It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using confocal microscopy.
