NIST data: Enabling the technical-basis for evacuation planning of high-rise buildings

Researchers at the National Institute of Standards and Technology (NIST) are stepping up the pace for designing safer building evacuations by releasing large, numerical data sets that track the movement of people on stairs during high-rise building evacuation drills. The data sets will ensure that architects, engineers, emergency planners and others involved in building design have a strong...

NIST finalizes initial set of smart grid cyber security guidelines

The National Institute of Standards and Technology has issued its first Guidelines for Smart Grid Cyber Security, which includes high-level security requirements, a framework for assessing risks, an evaluation of privacy issues at personal residences, and additional information for businesses and organizations to use as they craft strategies to protect the modernizing power grid from attacks,...

Research shows radiometric dating still reliable (again)

Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College,...

Review: How the iPad won over a skeptic

(AP) -- At first glance, the iPad looked like a heavy, overgrown iPod Touch. After just a few months of use, however, this iPad skeptic realized that it's so much more - it's one of those devices I've always needed. Those don't come around very often.

With so many birds remaining in the wild the chances of conservation success are greatly improved -- welcome news for this Critically Endangered bird...

Scientists glimpse 'dance of skeletons' inside neurons: Insight into developmental disorders, including Williams syndrome

Scientists have uncovered how a structural component inside neurons performs two coordinated dance moves when the connections between neurons are strengthened. The discovery hints at why people with Williams syndrome, a developmental disorder caused by a deletion of several genes, including one that alters dendritic spine remodeling, have such an unusual blend of cognitive strengths and...
