• Buildings made of prefabricated straw prove to be fire-resistant

    Researchers at Bath University test panels made from prefabricated straw-bale and hemp by exposing them to temperatures over 1,000°C; to reach the required building standard, the panels had to withstand the heat for more than thirty minutes, but more than two hours later — four times as long as required — the panels had still not failed

  • GE Global Research to develop wearable RFID chemical sensor

    GE Global Research will develop a wearable radio-frequency-identification (RFID) sensors to alert people to the presence of chemicals in the air; as the sensors can be made at a size smaller than a penny, they could form part of an identification badge that would provide an early warning for people about the presence of chemical agents

  • NASA develops chemical-detection app for iPhone

    NASA’s Homeland Security Cell-All program has developed an intriguing application to Apple’s phone in the form of a stamp-sized chemical sniffing device; the prototype chemical sensor can sniff small amounts of chemicals like methane, ammonia, and chlorine gas

  • Oregon's bridges to be readied for the Big One

    There are 2,671 bridges in Oregon’s highway system; researchers develop a computer model which, for the first time, gives state authorities bridge-by-bridge estimates of damage, repair cost, and traffic delay costs associated with a shattering western Oregon quake; the new tool would allow engineers to prioritize which of the state’s bridges should get seismic upgrades

  • Researchers look for a better way to build bridges

    Canadian researchers look for ways to make bridges sturdier; one project looks at the use of advanced fiber-reinforced polymers (FRPs) to protect critical concrete infrastructure against extreme shocks; the second study involves the use of ultra high-performance concrete (UHPC) to build long-life, lightweight and cost-effective bridges

  • Interference-free radio from Cambridge Consultants

    Cambridge Consultants shows a novel “spectral sensing” cognitive radio technology that will allow any radio product to transmit without interference over the so-called “whitespace” frequencies recently vacated by the U.S. digital TV switchover

  • DARPA looking for methods to freeze soldiers with brain injuries

    Traumatic brain injuries are caused by repeated exposure to blasts, specifically the “supersonic wave” of highly-pressurized air they emit; within a fraction of a second after impact, brain cells, tissues, and blood vessels are stretched, torn, and distorted; over the hours, days, and months that follow, altered brain processes create a snowball effect of damage — which is why symptoms often don’t show up until troops come home; in its solicitation, DARPA notes that a portable brain-cooling unit, deployed in the field, could “extend the golden hour of patient survivability and increase the chances for full recovery”

  • Anticipating new diseases, bioterror methods

    The 150 researchers at the University of Florida’s Emerging Pathogens Institute work to anticipate and respond to new diseases and old ones — such as tuberculosis and cholera — that can turn into new threats or make a comeback

  • U.S. Navy's PANDA technology to detect "deviant" ships

    There are tens of thousands of ships on the high seas every day, carrying millions of containers, entering and leaving hundreds of ports in dozens of countries; monitoring this vast amount of traffic to make sure that none of the containers is carrying WMDs is humanly impossible; Lockheed Martin has developed the PANDA Maritime Domain Awareness program to help the U.S. Navy and intelligence community keep a closer eye on the global maritime traffic

  • E.coli helps mend cracked pipes

    Aberdeen University students show how specific strains of E. coli, which are not deadly or poisonous to humans, could be used automatically to mend cracks that occur in household water pipes, cooling pipes in laboratory experiments, or water pipes in power plants

  • Imperial College London awarded £4.9 million to research cloaking properties of metamaterials

    Metamaterials have properties that could lead to the development of invisibility “cloaking” devices, sensitive security sensors, and flat lenses that can be used to image objects much smaller than the wavelength of light; Imperial College London receives a £4.9 million grant to do research on metamaterials

  • Ricin antidote ready for production

    U.K. scientists develop the first antidote to ricin poisoning; security experts say ricin — roughly 1,000 times more toxic than cyanide — could be used in a bio-terror attack; what worries experts about ricin is not only its toxicity, but its ready availability: Ricin is extracted from castor beans, which are processed throughout the world to make castor oil; the toxin is part of the waste “mash” produced when castor oil is made

  • Los Alamos lab's toxic waste seeps toward New Mexico's water sources

    Radioactive debris has been found in canyons that drain into the Rio Grande, but officials at the Los Alamos National Laboratory say there is no health risk; to comply with New Mexico’s clean up orders, the lab has installed about 300 monitoring wells and gauges, contaminated soil is being removed from canyon bottoms, wetlands are being planted, and small dams built to arrest the flow of polluted storm water

  • Downtown airport boasts a new runway safety system

    Safety barriers made of new type of absorbing concrete are installed at a Kansas City airport; the barriers are made of concrete blocks which collapse to absorb the energy of the airplane while minimizing the damage to the aircraft and allowing the aircraft to be slowed without hurting passengers

  • Rise in the number of U.S. students majoring in engineering

    Engineering schools are seeing a surge of interest, spurred in part by reports that engineering grads earn higher starting salaries than their classmates
