Until recently people believed much of the rain forest’s carbon floated down the Amazon River and ended up deep in the ocean. Research showed a decade ago that rivers exhale huge amounts of carbon dioxide, though it left open the question of how that was possible. A new study resolves the conundrum, proving that woody plant matter is almost completely digested by bacteria living in the Amazon River.
Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications. The Duke engineers, using a new catalytic approach, have shown in the laboratory that they can reduce carbon monoxide levels to nearly zero in the presence of hydrogen and the harmless byproducts of carbon dioxide and water.
The solar industry in Georgia is pushing a power monopoly to expand its use of solar energy as it plans to meet the state's electricity needs over the next two decades. State utility regulators heard testimony Tuesday on the energy plans from Southern Co. subsidiary Georgia Power, which must submit new plans every three years.
You're standing near an airport luggage carousel and your bag emerges on the conveyor belt, prompting you to spring into action. How does your brain make the shift from passively waiting to taking action when your bag appears? A new study from investigators at the University of Michigan and Eli Lilly may reveal the brain's "switch" for new behavior.
Sandia National Laboratories has developed key components of a software tool to help the Army's PEO GCS analyze countless what-if scenarios that can be manipulated as technology advances and the global environment, the federal budget, or other factors change. Sandia calls this advanced combination of modeling, simulation, and optimization decision support software the Capability Portfolio Analysis Tool (CPAT).
Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron and platinum with an ordered crystal structure.
Prior Scientific has introduced the H101 flat top stage, a motorized, high-precision microscope stage for upright microscopes. The design of the H101 incorporates a flat top plate, eliminating obstacles to objective rotation.
E Instruments’ Model 7899 gas sniffer is a portable, rugged, and easy-to-use leak detection tool for HVAC professionals. The leak detector is equipped with a sensitive tip to pin-point small leaks of combustible gases and hydrocarbons from piping and/or appliances.
A new study has identified two unique methods for storing energy using wind power. A team from Pacific Northwest National Laboratory and Bonneville Power Administration has located two sites in Washington that could serve as multi-megawatt facilities. They say power for about 85,000 homes each month could be stored in porous rocks deep underground for later use.
Columbia University has signed a licensing agreement with Varian Medical Systems for new imaging software that facilitates 3D segmentation, the process by which anatomical structures in medical images are distinguished from one another—an important step in the precise planning of cancer surgery and radiation treatments.
Pulsars rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. Their predictability could be useful for future navigation systems. Built to test and validate next-generation X-ray navigation technology, the Goddard X-ray Navigation Laboratory Testbed will demonstrate the feasibility of this approach.
A fried breakfast food popular in Spain provided the inspiration for the development of doughnut-shaped droplets that may provide scientists with a new approach for studying fundamental issues in physics, mathematics, and materials. The doughnut-shaped droplets, a shape known as toroidal, are formed from two dissimilar liquids using a simple rotating stage and an injection needle.
Over the past few decades, scientists have developed many devices that can reopen clogged arteries, including angioplasty balloons and metallic stents. While generally effective, each of these treatments has drawbacks, including the risk of side effects. A new study analyzes the potential usefulness of a new treatment that combines the benefits of angioplasty balloons and drug-releasing stents, but may pose fewer risks.
In a new business, sometimes the better part of wisdom is knowing when to quit, a new study concludes. Even though persistence is a key to business success, entrepreneurs might be more successful if they not only knew when to start a business and take risks, but also knew when to abandon it and find something that provides a greater opportunity, the research team concluded.
Waterproof fabrics that whisk away sweat could be the latest application of microfluidic technology developed by bioengineers at the University of California, Davis. The new fabric works like human skin, forming excess sweat into droplets that drain away by themselves, says inventor Tingrui Pan.
