• Why some immigrants get citizenship

    For immigrants, the path to citizenship in many countries is filled with hurdles: finding a job, learning the language, passing exams. For some people, however, the biggest obstacle of all may be one they cannot help: their country of origin.

  • Conflicting cultural identities foster political radicalism

    New research suggests that dual-identity immigrants — first-generation immigrants and their descendants who identify with both their cultural minority group and the society they now live in — may be more prone to political radicalism if they perceive their two cultural identities to be incompatible.

  • The historical probability of drought

    Droughts can severely limit crop growth, causing yearly losses of around $8 billion in the United States. It may be possible, however, to minimize those losses if farmers can synchronize the growth of crops with periods of time when drought is less likely to occur. Researchers are working to create a reliable “calendar” of seasonal drought patterns that could help farmers optimize crop production by avoiding days prone to drought.

  • Military electronic devices disappear into the surroundings after use

    Electronic devices have become necessary for military operations, but it is almost impossible to track and recover every device. At the end of operations, these devices are often found scattered across the battlefield and might be captured by the enemy and repurposed or studied to compromise DoD’s strategic technological advantage. New DARPA program — Vanishing Programmable Resources (VAPR) program — seeks transient electronics, that is, devices which would maintain the current functionality and ruggedness of conventional electronics, but, when triggered, be able to degrade partially or completely into their surroundings.

  • Biometric workshop studied voice, dental, oral standards

    The National Institute of Standards and Technology (NIST) hosted a workshop to discuss proposed supplements to the biometric data format standard that support voice recognition, dental and oral data, disaster victim identification, and special data needs for mobile ID applications.

  • Projected U.S. water use to increase as climate warms

    Despite increases in efficiency, water demand in the United States is likely to increase substantially in the future if climate continues to warm, new projections indicate.

  • Laser scanner documents crimes scenes quickly, accurately

    See video

    The Carlsbad, California police is using a new laser scanner to capture what happened at crime scene. Thenew technology cuts the time it takes to document a crime scene, from the size of the room to the bullet holes in the wall, by up to 80 percent.

  • Maryland counties debate funding stormwater drainage management

    A new tax aimed at property owners could finance the first set of improvements of the drainage works in Salisbury, Maryland since the original system was laid almost a century ago. City leaders have been arguing since 2009 over dedicating a source of funding to stormwater management, when an environmental panel recommended it. In the past, funding for projects like this has been hard to find as other priorities were deemed more important.

  • Developing educational materials, courses on standards

    So called “documentary standards,” generally developed by industry-based committees, significantly influence industry, commerce and even daily life, but their role is often unrecognized save by those people who are immediately concerned.

  • Using silicon to produce hydrogen on demand

    Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to researchers. In a series of experiments, the scientists created spherical silicon particles about ten nanometers in diameter. When combined with water, these particles reacted to form silicic acid (a nontoxic byproduct) and hydrogen — a potential source of energy for fuel cells.

  • NIST seeking partners for graduate fellowship programs in science, engineering, math

    The National Institute of Standards and Technology (NIST) is seeking one or more qualified institutions or organizations to work with it in developing and implementing a fellowship program to afford doctoral-level graduate students opportunities to work at NIST laboratories on research topics in science, technology, engineering, and mathematics.

  • Improving cities by using the notion of “urban metabolism”

    As is the case with organisms, cities need energy, water, and nutrients, and they need to dispose of wastes and byproducts in ways which are viable and sustainable over the long run. This concept of “urban metabolism” is a model for looking systematically at the resources that flow into cities and the wastes and emissions that flow out from them in order better to understand the environmental impacts of cities and to highlight opportunities for efficiencies, improvements, and transformation.

  • “Rebound” effect of energy-efficient technology exaggerated

    The argument that those who have fuel-efficient cars drive them more and hence use more energy is overplayed and inaccurate. Researchers find evidence that, indeed, if a technology is cheaper to run – for example, a fuel-efficient car — people may use it more, but the effects of an increased use of the technology are too small to erase energy savings from energy efficiency standards and energy-efficient technologies.

  • Blast-resilient carriages to reduce impact of a terrorist attack on trains, metros

    Engineers have developed a blast-resilient carriages which are better able to withstand a terrorist attack and ultimately save lives. The engineers have e focused on two key areas — containing the impact of the blast and reducing debris — the main cause of death and injury in an explosion and the key obstacle for emergency services trying to gain access to injured passengers.

  • Exploring asteroids for commercial metal harvesting

    Deep Space says that in a decade, it will be harvesting asteroids for metals and other building materials, to construct large communications platforms to replace communications satellites, and later solar power stations to beam carbon-free energy to consumers on Earth. “More than 900 new asteroids that pass near Earth are discovered every year. They can be like the Iron Range of Minnesota was for the Detroit car industry last century,” says the company’s CEO.
