Marine Lab Tracks Pollutants in Dolphins and Beluga Whales
National Institute of Standards and Technology (NIST)

Bottlenose dolphins and beluga whales, two marine species at or near the top of their respective food webs, accumulate more chemical pollutants in their bodies when they live and feed in waters near urbanized areas, according to scientists working at the Hollings Marine Laboratory, a government-university collaboration in Charleston, S.C.

Silver Cycle: New Evidence for Natural Synthesis of Silver Nanoparticles
National Institute of Standards and Technology (NIST)

A NIST study adds an additional wrinkle to concerns over what happens to silver nanoparticles after they are released into the environment: nature may be making silver nanoparticles on its own.

NIST Prototypes Framework for Evaluating Sustainability Standards
National Institute of Standards and Technology (NIST)

The large number of planet-friendly standards and regulations creates a sometimes-confusing array of options for “going green.” NIST researchers have prototyped a framework to help organizations of all types sort through the welter of choices and evaluate and implement sustainability standards most appropriate for their operations and interests.

Understanding How Glasses 'Relax' Provides Some Relief for Manufacturers
National Institute of Standards and Technology (NIST)

Researchers at the National Institute of Standards and Technology (NIST) and Wesleyan University have used computer simulations to gain basic insights into a fundamental problem in material science related to glass-forming materials, offering a precise mathematical and physical description of the way temperature affects the rate of flow in this broad class of materials—a long-standing goal.

Travel Hazards: Two Studies Start to Map Pollutant Threats to Turtles
National Institute of Standards and Technology (NIST)

In a pair of studies, researchers at the Hollings Marine Laboratory report that persistent organic pollutants (POPs) are consistently showing up in the blood and eggs of loggerhead sea turtles, that the turtles accumulate more of the contaminant chemicals the farther they travel up the Atlantic coast, and that the pollutants may pose a threat to the survival of this endangered species.

Good Eggs: Nanomagnets are Food for Thought on Computer Memories
National Institute of Standards and Technology (NIST)

Magnetics researchers at the National Institute of Standards and Technology (NIST) colored lots of eggs recently. Bunnies and children might find the eggs a bit small—in fact, too small to see without a microscope. But these "eggcentric" nanomagnets have another practical use, suggesting strategies for making future low-power computer memories.

Free Online Tool Aids Decisions on Fire Sprinkler Systems for Homes
National Institute of Standards and Technology (NIST)

A new, Web-based "sprinkler use decisioning" tool developed by the National Institute of Standards and Technology (NIST) enables experts and non-experts alike to assess the cost-effectiveness of fire sprinklers for their particular jurisdiction, development, or dwelling.

The Heat Is On: NIST Zeroes In On Energy Consumption of Ice Makers
National Institute of Standards and Technology (NIST)

In tests of four different refrigerators, National Institute of Standards and Technology (NIST) researchers found that ice makers increased rated energy consumption by 12 to 20 percent, with most of that additional energy cost due to the electric heaters used to release ice from molds.
