The incidence of racial hate crimes increased by 20% when a new broadband provider entered an area
New research from Carlson School of Management Professor Jason Chan and NYU Stern Professors Anindya Ghose and Robert Seamans finds that broadband availability increased the incidence of racial hate crimes committed by lone-wolf perpetrators in the United States during the period 2001-2008. The addition of a single broadband provider led to as much as a 20 percent rise in racial hate crimes in areas where racial tensions were especially high.(more…)
It’s been a decade since a swarm of relatively mild earthquakes shook up parts of Spokane. Now, armed with the right tools, scientists want to find out what was at fault.
“It was always something not as well understood as we thought it should be,” said Douglas Gibbons, a University of Washington researcher in Earth and space sciences, who is guiding installation of strong-motion sensors as part of a project called NetQuakes.
NetQuakes will install a half-dozen seismometers in the Spokane area by the end of June, mostly in volunteers’ homes, to help improve understanding of what lies beneath the city. (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…)
