Duke University team develops nuclear terrorism detection tool
If terrorists detonate a nuclear bomb or a dirty bomb in a city, first responders rushing to the scene would have to sort out the thousands of victims exposed to the harmful effects of radiation to see who needs more immediate attention and who can wait; current tests for radiation poisoning take a number of days to complete, which is too slow; Duke University researchers develop a device which uses genomic technology to capture molecular snapshots of genes or patterns of genes that are “turned on” or “turned off” in the body’s response to radiation; this allows emergency crews to determine the severity of radiation poisoning in under 30 minutes

Market for first responders, law enforcement robotics to see robust growth
Market for first responders and law enforcement robotics reached $203.1 million in 2009; it is anticipated to reach $3.7 billion by 2016; market growth will come as border patrols and law enforcement agencies use robots to achieve broader security in a less expensive manner

UC Berkeley researchers develop a robot that folds towels
Researchers build a robot that can reliably fold towels it has never “seen”; the solution addresses a key issue in the development of robotics: many important problems in applying robotics and computer vision to real-life missions involve deformable objects, and the challenges posed by robotic towel-folding reflect important challenges inherent in robotic perception and manipulation for deformable objects

Protecting structures by tracking down rust
Damage to concrete bridges caused by rust can have fatal consequences, at worst leading to a total collapse; now, researchers have developed an early-warning system for rust; sensor-transponders integrated in the concrete allow the extent of corrosion to be measured

Detecting structural defects with wind and water
Bridges, aircraft, and wind turbines are in constant movement; natural forces and pedestrians all create vibrations; previously, time-consuming tests were needed to determine how building components would react to vibrations; now, researchers have developed a simpler method

DARPA director urges universities to create and “elite army of futuristic technogeeks”
Between 2001 and 2008, DARPA’s funding to research schools was cut in half; less funding meant fewer graduate students: Combined with a 43 percent decrease in computing and science enrollment among undergrads, this means a shortage in technologists in the making; DARPA chief wants this trend reversed

Five ways to make subway stations and cars safer
Several new technologies and practices can make subways and mass-transit stations significantly safer; among the latest technologies: shields, vests, and blankets made from Demron, a fabric blend that blocks chemical, biological, and nuclear agents; the shields and vests would be used by first responders, while blankets would be thrown over radiation victims to keep them from irradiating others; another blanket — the Hi-Energy Nuclear Suppression Blanket — is designed to be placed over a dirty bomb about to go off; it traps chemical, biological, and nuclear agents and reduces by more than half the distance they can spread

Aircraft carrier like on-land mobile airport concept studied
A study of the concept of creating mobile airports receives £2 million in private funding; the idea is for airplanes to take off and land on aircraft carrier-like runways traveling on the motorway; one of the most challenging aspects of this new concept is building catapults capable of launching a Boeing 767 in same way fighter jets are boosted off navy aircraft carriers

Russia builds stealth navy
Russia is turning part of its navy into a stealth navy; the project uses stealth technology to reduce the ship’s secondary radar field, as well as its acoustic, infrared, magnetic, and visual signatures; two corvettes have already been floated, and Russia plans to have up to thirty vessels of this class

Biochip technology reveals fingerprints of biochemical threats
The biochip offers a chance to determine the signatures of biological agents that can be used for bioterrorism, most notably the bacterium that causes anthrax, Bacillus anthracis; while some scientists have used DNA analysis to identify particular strains of the anthrax bacterium, the biochips help scientists and government officials learn how anthrax bacteria are grown, narrowing the pool of potential suspects

Winners of the annual Rube Goldberg Machine Contests
Rube Goldberg machines combined simple household items into complex devices to perform trivial tasks; the machines combine the principles of physics and engineering, using common objects; the theme for the 2010 national Rube Goldberg contest: to build a machine which would dispense an appropriate amount of hand sanitizer in someone’s hand — and do so in at least twenty steps; a University of Texas team built a machine that dispenses the hand sanitizer in 46 steps

Cutting-edge laser technology for crime labs developed by FIU research team
Determining the precise composition of a substance with LIBS can provide important evidence in legal proceedings. Trace elemental analysis for comparisons of glass, paint chips, soils, paper, ink on paper, and metal fragments has been shown to be highly effective; the instrumentation required for this kind of analysis in forensic comparisons, however, has been beyond the reach of many forensic laboratories; researchers at Florida International University offers a solution

Day of trained sniffing bees is here
The bee’s discreet sense of smell, equivalent to a dog’s, is being exploited as a much cheaper way to detect various odors in the environment; a U.K. company is now training bees to sniff out explosives and land mines — but also to identify diseases and cancers in people and animals, detect rapidly spreading bacteria in food, and identify dry rot in buildings
