NIST Researchers Develop Standards to Help Eliminate ‘Forever Chemicals’ in Firefighting Foams
New reference materials containing PFAS will help the military and other organizations identify and phase out foams that contain these chemicals, which have raised environmental and health concerns. Read more about the PFAS reference materials.
What’s Wrong With This Picture? NIST Face Analysis Program Helps to Find Answers
Two NIST evaluation studies will help software better detect photo spoofs and image quality issues. Read more about the face analysis studies.
NIST’s Shrimp and Salmon Reference Materials Could Help Combat Seafood Fraud
NIST researchers developed reference materials for salmon and shrimp, two of the most-consumed seafoods in the U.S., to help regulators differentiate between farm-raised and wild-caught types. Read more about the seafood reference materials.
New Spin-Squeezing Techniques Let Atoms Work Together for Better Quantum Measurements
Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. Read more about the spin-squeezing techniques.

Measuring the Accuracy of PCR Tests Can Improve Health Care Beyond COVID-19
Researchers at NIST have developed a new mathematical model to characterize the likelihood of a test result being incorrect. Learn more about the PCR test research.
I’m Helping My Garden Vegetables — and My Students — Bloom Where They Are Planted
Middle school is the perfect time to plant the seed for a child to grow a lifelong love of science. Read more from one teacher about how NIST supports her work.
How Do You Measure the Age of a Tree?
Getting the answer, it turns out, is not trivial. In fact, it spawned an entire field of science: dendrochronology. Read more about how we measure a tree's age.
Improving Water Quality at Home
NIST researcher Alshae’ Logan-Jackson studied water temperature and water use in a laboratory house on NIST’s campus in Gaithersburg, Maryland. Learn more about the connections between these factors and dangerous bacteria in our new video on YouTube.
