The new database contains approximately 100 Reference Measurement Procedures, including 30 developed and maintained by NIST. The database lists 96 approved reference materials; NIST is the source for 72 of these, facilitating worldwide comparability of clinical measurements and reducing technical barriers to trade.
Researchers at the University of Rhode Island's Graduate School of Oceanography have received a $1.1 million NSF grant to study the impact of Earth's rotation on ocean circulation and mixing. The grant will be used to simulate the rotation of the earth and investigate horizontal stirring in the ocean caused by small eddies.
Researchers have developed a new technique called X-ray standing wave imaging, which enables direct visualization of ion site distributions at mineral-water interfaces. This breakthrough streamlines the tedious process of structure determination, allowing scientists to complete data acquisition and analysis in under 24 hours.
Researchers at NIST have developed a chip-scale device that uses magnetic force microscopy to manipulate individual biomolecules. The device can stretch, twist, and uncoil strands of DNA with piconewton forces, paving the way for genomic studies.
The National Institute of Standards and Technology (NIST) has released a new collection of critically evaluated phase diagrams, improving search capabilities and reducing design errors. The ACerS-NIST collaboration saves research time and money by providing reliable data.
Prostate cancer cell lines exhibit high levels of free radical damage and defective repair mechanisms, leading to a cascade of events culminating in further DNA damage and cellular dysfunction. The new research provides solid evidence for the critical role of free radicals and repair in prostate cancer development.
A new three-step process developed by NIST's Office of Applied Economics evaluates the vulnerability of facilities to terrorist threats, considering engineering, management, and financial strategies. The tool assesses the most cost-effective combination of risk reduction strategies to protect facilities from damages.
The study reveals that oysters' immune blood cells contain rhombohedral-shaped crystals used to form shell. The research aims to understand biomineralization for potential breakthroughs in medical and material sciences.
Children in poorer families face greater family turmoil, violence, instability and smaller social networks, living in more polluted and crowded environments with inadequate services. They attend underfunded schools and spend less time reading, watching fewer books at home.
Researchers at Purdue University have discovered self-assembling nanotubes that attach better to titanium-coated implants than uncoated ones, promoting new cell growth and potentially leading to longer-lasting artificial joints. The nanotubes offer promise in biomedical applications and could be tailored for specific parts of the body.
NIST's new reference material, calibrated microspheres coated with fluorescent dye, provides an authoritative national fluorescence measurement scale. This improvement enables more accurate measurements of signal intensity, reflecting numbers of target molecules in samples.
