High-speed bi-directional wireless technology that uses light to send information securely offers faster, safer transfer of data than conventional wi-fi. Because it does not rely on the radio spectrum, it provides 10,000 times more bandwidth. Light-enabled wi-fi, or Li-Fi, was first developed by Professor Harald Haas, Chair of Mobile Communication with the University of Edinburgh. Haas is co-founder of the spin-out company pureLiFi.

This 50X photo shows cross-cut through an assembly of two dark-brown fiber-reinforced composite pieces, which are bonded together with gray adhesive and back-filled with a blue mass of composite material. 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 reflected light and darkfield.
This 200X photo shows the freshwater flea Daphnia magna. 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 differential interference contrast and image stacking.
The supply chain is ground zero for several recent cyber breaches. Hackers, for example, prey on vendors that have remote access to a larger company's global IT systems, software and networks. In the 2013 Target breach, the attacker infiltrated a vulnerable link: a refrigeration system supplier connected to the retailer's IT system. A counter-measure, via a user-ready online portal, has been developed at the Supply Chain Management Center.
Earth is on pace to tie or even break the mark for the hottest year on record, federal meteorologists say. That's because global heat records have kept falling in 2014, with September the latest example. The National Oceanic and Atmospheric Administration announced October 20, 2014, that last month the globe averaged 60.3 degrees Fahrenheit (15.72 degrees Celsius). That was the hottest September in 135 years of record keeping.
This 10X photo shows the surface details of a one euro coin. 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 reflection microscopy, Z-stacking and maximum intensity projection.
The drug creation process often misses many side effects that kill at least 100,000 patients a year. LLNL researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions, using high-performance computers to process proteins and drug compounds in an algorithm that produces reliable data outside of a laboratory setting for drug discovery.
Through a computational algorithm, researchers have developed a neural network that allows a small robot to detect different patterns, such as images, fingerprints, handwriting, faces, bodies, voice frequencies and DNA sequences. Nancy Guadalupe Arana Daniel focused on the recognition of human silhouettes in disaster situations.
What do the DNA in Australian seaweed, Amazon River water, tropical plants, and forest soil all have in common? Lots, say scientists. And understanding the genetic similarities of disparate life forms could enable researchers to produce compounds for new medicines, eco-friendly materials, more resilient crops, and cleaner air, water and energy.
The purpose of this series is to discuss the impact of GMP (Good Manufacturing Practice) regulations on cloud computing and to debate some of the regulatory issues facing an organization contemplating this approach. In this part, we look at the applicable regulations.
A profound new discovery reveals how the intimate act of sexual intercourse first evolved in our deep distant ancestors. In one of the biggest discoveries in the evolutionary history of sexual reproduction, Flinders University Professor John Long has found that internal fertilization and copulation was invented by ancient armored fishes, called placoderms, about 385 million years ago in Scotland.
The HPC Advisory Council and ISC High Performance call on undergraduate students from around the world to submit their application for partaking in the 2015 Student Cluster Competition (SCC). The 11 teams selected will receive the opportunity to build a small cluster of their design and run a series of benchmarks and applications in real time for four days, on the ISC 2015 exhibition floor.
IBM will pay $1.5 billion to Globalfoundries in order to shed its costly chip division. IBM Director of Research John E. Kelly III said in an interview on October 20, 2104, that handing over control of the semiconductor operations will allow it to grow faster, while IBM continues to invest in and expand its chip research.
The DOE’s Energy Sciences Network, or ESnet, is deploying four new high-speed transatlantic links, giving researchers at America’s national laboratories and universities ultra-fast access to scientific data from the Large Hadron Collider and other research sites in Europe. ESnet’s transatlantic extension will deliver a total capacity of 340 gigabits-per-second, and serve dozens of scientific collaborations.
When ESnet engineers began to study the idea of building a new 100 Gbps network between the US and Europe, a primary concern was ensuring the service would be robust and built from multiple underlying links — so that if one went down, researchers could still rely on sufficient bandwidth. Based on data collected by Caltech physicist and networking pioneer Harvey Newman, the team understood multiple cables are sometimes cut simultaneously.
The Jefferson Project announced new milestones in a multimillion-dollar collaboration that seeks to understand and manage complex factors impacting Lake George. A new data visualization laboratory features advanced computing and graphics systems that allow researchers to visualize sophisticated models and incoming data on weather, runoff and circulation patterns. The lab will display streaming data from various sensors in real-time.
