• Sensors monitor bridges’ health – and tweet the information they gather

    While bridge collapses are rare, there have been enough of them to raise concerns in some parts of the world that their condition is not sufficiently monitored. Sweden is taking a hi-tech approach to its aging infrastructure. Researchers are rigging up the country’s bridges with multiple sensors that allow early detection of wear and tear. The bridges can even tweet throughout the course of a day.

  • Nanobionic spinach plants can detect explosives

    By Anne Trafton

    Spinach is no longer just a superfood: By embedding leaves with carbon nanotubes, MIT engineers have transformed spinach plants into sensors that can detect explosives and wirelessly relay that information to a handheld device similar to a smartphone. This is one of the first demonstrations of engineering electronic systems into plants, an approach that the researchers call “plant nanobionics.”

  • Nuclear CSI: Noninvasive procedure could spot criminal nuclear activity

    Determining whether an individual – a terrorist, a smuggler, a criminal — has handled nuclear materials, such as uranium or plutonium, is a challenge national defense agencies currently face. The standard protocol to detect uranium exposure is through a urine sample; however, urine is able only to identify those who have been recently exposed. Scientists have developed a noninvasive procedures that will better identify individuals exposed to uranium within one year.

  • New 3-D crime-scene forensics technology

    Researchers are developing a new type of portable crime-scene forensics technology designed to take precise high-resolution 3-D images of shoeprints and tire tread marks in snow and soil. The system will cost around $5,000, which is about one-tenth the cost of systems commercially available, and represents an alternative to the traditional method of plaster casting.

  • Bolstering energy security with homegrown energy sources

    The U.S. Department of Energy has a goal to develop and demonstrate transformative bioenergy technologies to fuel a more sustainable nation. Reaching that goal will require roughly a billion tons of biomass, so we will need to rely on a variety of resources to get the job done.

  • China’s quantum satellite could make data breaches a thing of the past

    By Robert Young

    China recently launched a satellite into orbit with a unique feature: it has the ability to send information securely, not with mathematical encryption but by using the fundamental laws of physics. China will be the first country to achieve this feat, and it marks a milestone in the development of quantum technologies. The next revolution in technology promises to embrace fundamental laws of physics to enable devices to perform operations that are beyond the bounds of current electronics. For practical quantum communications we need devices integrated into our computers and smartphones that exchange data in a similar way to the quantum satellite. These devices are thankfully just around the corner. In a few years we may look back on digital eavesdropping and massive information breaches from databases as a problem buried in the past.

  • DHS S&T announces 10 start-ups for first responder technology innovation

    DHS S&T has announced the selection of ten startup companies to be part of EMERGE 2016: Wearable Technology, a program designed to bring startups, accelerators, and other strategic partners together in a common research and development effort. The program is focused on wearable technology that can be modified specifically for first responders.

  • Half of U.S. business R&D concentrated in five states

    Five states accounted for just over half of the $255 billion of research and development (R&D) companies paid for and performed in the United States in 2013. The five states with the highest levels of business R&D performance — California, Massachusetts, Michigan, Texas, and Washington — accounted for $133 billion, or 52 percent, of the total.

  • X-ray vision: Bomb technicians strengthen their hand with Sandia’s XTK software

    X-Ray Toolkit (XTK), an image-processing and analysis software developed at Sandia National Laboratories, has been adopted by the military and emergency response communities in the United States and around he world. “XTK is the standard in the field not only nationally, but internationally. It made the average bomb tech a better bomb tech,” said Craig Greene, a special agent and bomb technician at the Albuquerque, New Mexico FBI. “In the past twenty years, the bomb technician community has progressed from the Stone Age to the twenty-first century in terms of equipment and procedures, and XTK is a major part of that progression.”

  • DHS takes delivery of RadSeeker which identifies threat materials in shielded, masked, or concealed situations

    The first regular shipments of the Smiths Detection RadSeeker featuring Symetrica’s Discovery Technology Sub-System will begin this fall as the first part of a contract with the Department of Homeland Security (DHS). Symetrica’s Discovery Technology at the heart of RadSeeker identifies threat materials in shielded, masked, or concealed situations.

  • New forensic method identifies people using human hair proteins

    In an important breakthrough for the forensic science community, researchers have developed the first-ever biological identification method that exploits the information encoded in proteins of human hair. The new protein identification technique will offer another tool to law enforcement authorities for crime scene investigations and archaeologists, as the method has been able to detect protein in human hair more than 250 years old.

  • Large-scale metamaterials could earthquake-proof buildings in tremor-prone regions

    Metamaterials – artificial structures that exhibit extraordinary vibrational properties – could come to the rescue of regions threatened by earthquakes, according to new research. The study, performed by researchers in Europe and involving detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks.

  • Wider temperature tolerance is based on ion-pair-coordinated polymers

    A new class of fuel cells based on a newly discovered polymer-based material could bridge the gap between the operating temperature ranges of two existing types of polymer fuel cells, a breakthrough with the potential to accelerate the commercialization of low-cost fuel cells for automotive and stationary applications.

  • SayVU security app – developed by a BGU graduate student -- deployed at Rio Olympics

    A new app, SayVU, conceived as a graduate student project at Ben-Gurion University of the Negev, is being deployed at the 2016 Rio Olympics. International Security & Defense Systems (ISDS), the security integrator for the Olympics, selected SayVU as one of the Israeli technologies being used to protect attendees. SayVU enables a user to send a distress signal to an emergency hotline even if a phone is locked and without having to access the application. The message can be sent in a number of ways; shaking the device, tapping the camera button, or simply speaking into the phone.

  • “Liquid fingerprinting” technique identifies unknown liquids instantly

    A new company — Validere — will commercialize sensing technology invented at Harvard University that can perform instant, in-field characterization of the chemical make-up and material properties of unknown liquids. Validere aims to develop the licensed technology, called Watermark Ink (W-INK), into a pocket-sized device that could be used by first responders to quickly identify chemical spills, or by officials to verify the fuel grade of gasoline right at the pump.
