New publication offers security tips for WiMAX networks
Government agencies and other organizations planning to use WiMAX- Worldwide Interoperability for Microwave Access-networks can get technical advice on improving the security of their systems from a draft computer security guide prepared by the National Institute of Standards and Technology (NIST). view more (2009-10-07)
A new cloaking method
University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures... view more... (2009-08-17)
Artificial noise saves energy
Against the background of climate change, how can xDSL systems function more energy-efficiently and cost-effectively? Scientists are providing a solution combining existing methods which network providers could implement immediately. view more (2009-06-25)
Manatees can probably hear which directions boats approach from
The world is a perilous place for the endangered manatee. While the mammals are at risk from natural threats, human activity also poses a great danger to manatee numbers. view more (2009-06-12)
Scientists cable seafloor seismometer into state earthquake network
A newly laid, 32-mile underwater cable finally links the state's only seafloor seismic station with the University of California, Berkeley's seismic network, merging real-time data from west of the San Andreas fault with data from 31 other land stations sprinkled around Northern and Central California. view more (2009-03-19)
Spreading high-speed Internet to rural areas

Maintaining the brain's wiring in aging and disease
Researchers at the Babraham Institute near Cambridge, supported by the Alzheimer's Research Trust and the Biotechnology and Biological Sciences Research Council (BBSRC), have discovered that the brain's circuitry survives longer than previously thought in diseases of ageing such as Alzheimer's disease. view more (2008-12-08)
High speed broadband will create energy bottleneck and slow Internet
"Increased services like Video on Demand will put pressure on the system and create an energy bottleneck," said Dr Kerry Hinton of the University's Department of Electrical and Electronic Engineering and the ARC Special Centre for Ultra-Broadband Information Networks (CUBIN). view more (2008-11-25)
What to do with 15 million gigabytes of data
When it is fully up and running, the four massive detectors on the new Large Hadron Collider (LHC) at the CERN particle-physics lab near Geneva are expected to produce up to 15 million gigabytes, aka 15 petabytes, of data every year view more (2008-11-03)
Micro honeycomb materials enable new physics in aicraft sound reduction
Noise from commercial and military jet aircraft causes environmental problems for communities near airports, obliging airplanes to follow often complex noise-abatement procedures on takeoff and landing. It can also make aircraft interiors excessively loud. view more (2008-09-30)
2 for 1: NIST design enables more cost-effective quantum key distribution
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cryptography, the most secure method of transmitting data. view more (2008-05-30)
Broadband access opens doors to networking, economic development for rural areas
Proactive policies are needed to facilitate broadband Internet access and adoption in rural areas so that rural hospitals, schools and businesses can drive social and economic development and better position themselves to compete, say Penn State researchers in a recently released report from the Center for Rural Pennsylvania. view more (2008-05-20)
Emergency links: NIST identifies 'sweet spot' for radios in tunnels
As part of a project to improve wireless communications for emergency responders, researchers at the National Institute of Standards and Technology (NIST) have confirmed that underground tunnels-generally a difficult setting for radios-can have a frequency "sweet spot" at which signals may travel several times farther than at other... view more...

Get mobile, get promoted
Without that five minutes chat by the watercooler, the open-ended lunch break, or a boss's beckoning door, homeworkers can often feel isolated from colleagues and the opportunities for informal networking and mentoring that are wrought by the almost mythical 9-to-5. view more (2008-04-21)
Separate signals through optical fibres for ultrafast home network
