BAE and Portendo join forces on IED detector
The device aims a laser beam at a particular area suspected to hide an IED; the reflected light is collected by the apparatus and is analyzed using a Raman scattering method, which provides a unique molecular signature which can be compared against an explosives database; Raman spectroscopy has long been thought to hold promise for such applications, but it typically provides a very weak signal; until now

South Africa lax attitude to airport security worries FIFA
South Africa promised FIFA that it would tighten security at airports ahead of the World Cup games which open in three weeks; investigative reporters proved that promise hollow when they managed easily to pass security checks on ten flights — out of the twenty they tried to board — in the country with steak knives, screwdrivers, razors, pairs of scissors, and even syringes in their luggage

Iran's nuclear fuel swap is a sham; sanctions may still be imposed
Following a meeting in Tehran over the weekend of the leaders of Iran, Brazil, and Turkey, Iran said it agreed to send 1,200 kg of low-enriched uranium (LEU) to Turkey in exchange for 120 uranium rods enriched to 20 percent; Turkey and Brazil were quick to argue that there is no reason now for sanctions on Iran; the deal, though, is a sham; Iran has more than a ton of LEU left, and most importantly: it continues aggressively to enrich uranium and it has accelerated work on other components of a nuclear weapon

Tiny sensors embedded in cell phones identify, map airborne toxins in real time
Cell phones are everywhere people are, so University of California-San Diego’s researchers want to turn the devices into chemical sensors; the tiny sensor, a porous flake of silicon, changes color when it interacts with specific chemicals. By manipulating the shape of the pores, the researchers can tune individual spots on the silicon flake to respond to specific chemical traits

New detection technology identifies bacteria, viruses, other organisms within 24 hours
In the area of biodefense, current systems are centered on the detection of smaller prioritized sets of high-risk pathogens, rather than testing for a much broader spectrum of organisms; a new detection method from Lawrence Livermore allows not only the identification of the biological pathogens on a priority screening list, but also any other already-sequenced bacteria or virus in a sample that first responders, doctors, or regulatory agencies might not have been expecting to find, including possible novel or emerging pathogens

Engineers to enhance crane-mounted cargo scanning system
VeriTainer, a venture-backed specialist in crane-based radiation detection technology for scanning shipping containers, enters into a three-and-a-half years, $4 million n R&D agreement with Lawrence Livermore National Laboratory to enhance the gamma and neutron detection sensitivity of the company’s radiation scanners

Cobham develops more accurate, cost-effective landmine detector
The Red Cross estimates that 60-100 million mines are in place in 62 countries, causing 800 deaths each month; clearing mines is an expensive proposition, averaging £1m/km2; much of this cost is owed to high number of false alarms from metal detectors; British company develops a dual-sensor mine detector that enables nearly 33 percent more land to be cleared within existing budgets

Drive-by sniffing out of homemade bomb factories
Terrorists may not be safe for long — stealthily developing home-made explosives in their bath tubs; Swedish researchers are working on developing an explosive detection systems to be mounted atop police vehicles; the system would effectively monitor urban areas for possible bomb-making activities while on normal patrol; the system’s sensors would detect elevated levels of suspicious substances and then use integrated GPS technology to record the time and location the molecules are being emitted from

How to protect Times Square -- and other highly traveled areas
New Yorkers were lucky that a T-shirt vendor notices the suspicious SUV left by Faisal Shazad in Times Square, but there are ways to improve on luck in trying to secure highly traveled areas; more coordinated CCTV system, blast-mitigation, and more call boxes are a few of the measures

Karachi airport screeners stop man wearing therapeutic vibro-shoes
Pakistani airport security screeners stop a man wearing therapeutic vibro-shoes; X-ray operators were alarmed to note batteries and circuitry built into the soles of his shoes, but the gadgetry is meant to deliver soothing foot massage, not to explode a bomb

Non-toxic cleaners for terrorist attacks
Traditional chlorine- and lye-based cleaning agents are potentially hazardous and can react with chemical weapons and other materials in the environment to form new toxic substances; military researchers non-toxic, ultra-strength cleaners that could be used in the aftermath of a terrorist attack; the peroxide-based “green” decontaminants are tough enough to get rid of nerve gas, mustard gas, radioactive isotopes, and anthrax

New sensor speeds water analysis
New sensor creates a single procedure for in-situ monitoring of chlorinated hydrocarbons in water, obviating the need for laboratory-based technologies for the analysis of water contaminants, which are time consuming, labor intensive and expensive

Planned security network for Lower Manhattan would not have identified bomber
New York City plans to install a protection system in Lower Manhattan which will consist of surveillance cameras, license plate readers, and chemical sensors; the system will be able to record and track every vehicle moving between 34th and 59th Streets, river to river; because neither the S.U.V. used in the attempt last Saturday nor the license plate on it had been reported stolen, it would not have raised any immediate red flags
