Seabed cable signals to sense tsunamis
The current tsunami warning system relies on a global seismometer network to detect earthquakes that may indicate that a tsunami has formed; deep-ocean pressure sensors and coastal tide gauges are the only tools available to detect and measure an actual tsunami; the electric current induced in submarine cables may provide an additional way to confirm and track a tsunami; researchers suggest monitoring voltages changes across the vast network of communication cables on the seabed to enhance the current tsunami warning system

Bruker’s Autonomous Rapid Facility Chemical Agent Monitor advances to DHS Phase IIIb
Bruker uses its proprietary RAID Ion Mobility Spectrometry (IMS) technology for the Autonomous Rapid Facility Chemical Agent Monitor Program, which is designed for long-term monitoring of ambient air for the presence of hazardous chemical vapors in the interior or exterior of critical government buildings, subways, airports and other facilities; the company says it has also developed a new product – the DE-tector — which uses next-generation IMS technology with selectivity and specificity that approaches that of mass spectrometry

Hidden sensor network detects explosives
German researchers develop a covert sensor system that track people carrying explosive in busy transportation hubs; the system works using two separate sensory networks that gather chemical and kinetic information — the first is made up of a series of four to six rotating laser scanners that send pulses through corridors, walkways, or escalators at airports or railway stations; the second network consists of electronic sensors hidden in air vents and wall fixtures that provide chemical data on explosive materials

U.K. firm says its scanning technology meets security, privacy concerns
Cambridge, U.K.-based TeraView says it is developing terahertz body scanners which use light from upper end of the infra-red spectrum, with a wavelength between 0.1 and 1mm; the scanners do not produce an image but a “fingerprint” — rather than blurry pictures of naked tourists, a TeraView scanner would return absorbance data that could be automatically analyzed to approve travelers or alert airport staff to investigate further

African nations do not have the means for meaningful improvements in airport security
While some of the worst lapses, such as allowing spears or other potential weapons in carry-on luggage, seem no longer to occur, other aspects of airport security in Africa remain disquieting; One expert says that if airports in developing nations had to meet Western security standards, “they would ground all the airplanes, as simple as that”

Keeping underwear bombing in perspective
The Nigerian underwear bomber and the Saudi suicide bomber who hid explosives in his body cavities (although it now appears that he, too, was an underwear bomber) point to a new, if so far ineffective, tactics on the part of al Queda; how serious is this threat? One expert says we should keep three things in mind: the threat is not serious because of inherent limitations involved in carrying incendiaries inside the human body or one’s underwear; one of two of these bombers may go through, though; the sheer complexity inherent in the effort involved in trying to prevent this type of bombing may erases any theoretical benefits and gains beyond a certain point; we may have reached that point

Debate intensifies over full-body scanners
The Christmas Day near-bombing invigorated an already-keen interest in whole-body scanners; there is debate going on over the effectiveness – and health risks – of the two main technologies available: millimeter-wave radiation and backscatter radiation; some suggest soft chemical ionization as an alternative
