• 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

  • New method to develop latent fingerprints

    Most of the techniques currently used for developing fingerprints rely on the chemistry of the print, but as prints dry or age, the common techniques used to develop latent fingerprints, such as dusting or cyanoacrylate — SuperGlue — fuming often fail; Penn State professor says that using the physical properties of the fingerprint, not the chemistry of the substances left behind, would solve these problems

  • BP tries new, smaller capping device to plug Gulf gusher

    BP is lowering a new device — the top-hat cofferdam — in an effort to plug the oil leak at the bottom of the Gulf of Mexico; the top-hat is a 5-foot-tall, 4-foot-diameter structure and it weighs less than two tons; BP built the smaller dome after a much larger, four-story containment vessel, designed to cap the larger of two leaks in the well, developed glitches Saturday

  • Sensors emulate insects' acoustic capabilities

    Researchers build sensors emulating the way a mosquito senses an oncoming predator or the swat of a human hand; these sensors have the potential to improve the industrial use of acoustic sensors and actuators, from medical ultrasound imaging, non-destructive testing of materials, and even robot guidance

  • New forensic tool advances data recovery

    Data recovery for images will be applied to other file types; new text tool will make it possible to recover more data from corrupted hard drives; the text tool will examine fragmented chunks of files that may be distributed across a disk and analyze their content to see which ones likely go together

  • 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

  • Corps looking at water diversions to protect Louisiana coast

    The recent, 1,000-year Ohio River Valley rain event that is causing so much flooding in Tennessee and Kentucky is expected to make its way into the New Orleans area by 18 May doubling the current Mississippi River flow to 1 million cfs; The U.S. Army Corps of Engineers has an idea: diverting the excess water to push water out of sensitive wetland areas and keep away oil that has been drawing near shore since the 20 April explosion of the Deepwater Horizon rig

  • Apple patents heartbeat-recognition sensors for iPhone

    Apple’s new patent will allow iPhones to identify user’s heartbeats & mood; by integrating this technology with the iPhone, the handset can authenticate the user by seamlessly picking his or her heart rate instantly as soon as they pick up their phone; no password required or tedious scanning of fingerprints or faces

  • New video camera offers very high resolution from afar -- and up close

    A new, 360° surveillance video promises high-resolution detail, multiple views, and DVR features; coverage this sweeping, with detail this fine, requires a very high pixel count; the new camera has a resolution capability of 100 megapixels — this is as detailed as fifty full-HDTV movies playing at once, with optical detail to spare

  • Remotely controlled robot inspects dangerous structures

    A remotely controlled robot uses laser sensors to look inside damaged structures to look for survivors; when inside the structure, the robot takes multiple scans using Light Detection and Ranging (LIDAR) unit that takes up to 500,000 point measurements per second. It also can scan through walls and windows

  • 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

  • Manned troop supply helicopter converted to unmanned helicopter

    Lockheed Martin, Kaman convert a manned to an unmanned helicopter; the single-seat heavy-lift helicopter will deliver sling loads up to 6,000 lb at sea level and 4,300 lb at 15,000 ft
