Data analytics helps organizations hunt for cyber attacks
ARMONK, N.Y. – 31 Jan 2013: Advanced attacks, widespread fraud and the pervasive use of social media, mobile and cloud computing are drastically altering the security landscape. As organizations increasingly need to manage Big Data, the way that corporate data needs to be protected is rapidly changing. (more…)
Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.
These higher-quality images could allow breast tumors to be detected earlier and with much greater accuracy. One in eight women in the United States will be diagnosed with breast cancer during her lifetime.
The research is published the week of Oct. 22 in the early edition of the journal Proceedings of the National Academy of Sciences. (more…)
• Researchers invent novel technique by fabricating tiny holes in a single quarter-inch chip to boost data transfer rates
• Until now, it was not possible to transport terabits of data for existing parallel optical communications technology
• New prototype compactly and efficiently delivers ultra-high interconnect bandwidth to power future supercomputer and data center applications
LOS ANGELES – 08 Mar 2012: IBM scientists today will report on a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information per second, the equivalent of downloading 500 high definition movies. The report will be presented at the Optical Fiber Communication Conference taking place in Los Angeles.
With the ability to move information at blazing speeds – eight times faster than parallel optical components available today – the breakthrough could transform how data is accessed, shared and used for a new era of communications, computing and entertainment. The raw speed of one transceiver is equivalent to the bandwidth consumed by 100,000 users at today’s typical 10 Mb/s high-speed internet access. Or, it would take just around an hour to transfer the entire U.S. Library of Congress web archive through the transceiver. (more…)
Washington, D.C.— Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices. However, understanding—and ultimately controlling—this effect remains a challenge, because much about manganite physics is still not known. A research team lead by Maria Baldini from Stanford University and Carnegie Geophysical Laboratory scientists Viktor Struzhkin and Alexander Goncharov has made an important breakthrough in our understanding of the mysterious ways manganites respond when subjected to intense pressure.
