• 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.

  • Better predictions of Asian summer monsoons, tropical storms

    The amount of rainfall and number of tropical storms during the summer monsoon season greatly impact the agriculture, economy, and people in Asia. Though meteorologists and climate scientists have worked for years to develop helpful prediction systems, seasonal predictions of these two types of weather phenomena are still poor. Scientists have now made a promising breakthrough for predicting in spring both the summer monsoon rainfall over East Asia and the number of tropical storms affecting East Asian coastal areas.

  • Uranium mining debate divides Virginia

    In Virginia a fight has begun over whether to drill for uranium. Some feel the drilling, which would create about 1,000 jobs and bounty of tax revenue in addition to nuclear fuel, is important for a state whose main industries, such as tobacco and textiles, are failing. Those who oppose the drilling fear the contamination of drinking water in case of an accident, and a stigma from uranium which would deter people and businesses from moving to the area.

  • Keystone pipeline clears another hurdle as Nebraska governor approves project

    On Tuesday, Nebraska governor Dave Heineman notified President Obama that he approved the controversial Keystone XL pipeline to go through the state. This marks a significant step forward in the project, which was delayed by the administration last year.

  • South African study highlights African fuelwood crisis

    Researchers have found that at current consumption levels in the communal areas of Lowveld, South Africa, reserves of fuelwood could be totally exhausted within thirteen years. The consequences are significant, with around half of the 2.4 million rural households in the country using wood as their primary fuel source, burning between four and seven million tons per year.

  • Fracking generates less wastewater per unit of gas, but more overall

    Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. The scale of fracking operations in the Marcellus shale region – which stretches from New York to Virginia and accounts for about 10 percent of all natural gas produced in the United States today — is so vast, however, that the wastewater it produces threatens to overwhelm the region’s wastewater disposal capacity.

  • Large amounts of antibacterial agent used in soaps found in freshwater lakes

    When people wash their hands with antibacterial soap, most do not think about where the chemicals contained in that soap end up. A new study determined that the common antibacterial agent, called triclosan, used in soaps and many other products, is found in increasing amounts in several Minnesota freshwater lakes.

  • Thwarting facial-recognition, photo-tagging software

    Information about when and where photographed subjects were when their pictures were taken is readily disclosed through photos taken, and the information is disclosed and distributed without their permission. The problem has become even worse due to the popularization of portable terminals with built-in cameras and developments in SNS and image search technologies. Japanese researchers offer a solution: goggles or glasses which, when equipped with near-infrared LED emitter. :

  • DOE addresses rare earth, critical materials shortage

    The U.S. Department of Energy announced earlier this month that a team led by Ames Laboratory in Ames, Iowa, has been selected for an award of up to $120 million over five years to establish an Energy Innovation Hub which will develop solutions to the domestic shortages of rare earth metals and other materials critical for U.S. energy security.
