NIST and JILA researchers have achieved a significant milestone in the development of nuclear clocks, marking a new era in precision timekeeping. The international team has successfully demonstrated core technologies for a nuclear clock using thorium-229. This includes precise frequency measurements of nuclear transitions and establishing a direct frequency link between a nuclear transition and an atomic clock. The implications of this breakthrough are far-reaching, potentially enhancing GPS accuracy, improving internet speeds, and advancing fundamental physics research. While still in the experimental stage, this work lays the foundation for clocks with extraordinary precision - imagine a timepiece that wouldn't lose a second over billions of years.

Researchers at NIST have developed a game-changing imaging method for breast cancer using hyperspectral dark-field microscopy. This technique, which uses different wavelengths of light to identify cancerous cells without staining, offers real-time feedback during surgery. The result? Surgeons can ensure that all cancerous tissue is removed in one go, reducing the need for follow-up surgeries and improving patient outcomes. As breast cancer remains a leading cause of cancer-related deaths, advancements like these are crucial for enhancing treatment and care.

Scientists have made small red and blue lasers for years but producing these lasers tiny enough to fit on a chip – which are important for quantum sensing, communications and information processing – has posed a challenge. NIST researchers have now filled in this “green gap,” producing a chip-scale green and yellow lasers by modifying optical components known as microresonators.

Delivered right to your newsfeed, get a roundup of our Tech Beat e-newsletter content on LinkedIn! Sometimes one measurement is not enough. That’s the case when conducting breath tests of drivers suspected of being intoxicated by cannabis. So NIST is investigating whether two breath tests separated by a time interval might produce more accurate results. As the cannabis plant becomes more widely used in U.S. commerce, NIST is also engaged in efforts to help labs distinguish between different cannabis products, namely hemp, which is legal in all 50 states, and marijuana, considered a controlled substance. #ScienceAndTechnology #Science #Technology #Newsletter

For researcher Cassie Stoffer, the journey to NIST started with a love of math. As an undergrad, she learned that math can be applied to real-world problems, which drew her to physics. She would eventually come to NIST through the Summer Undergraduate Research Fellowship program and get the opportunity to work in research related to magnetic resonance imaging, or MRI. The experience of working in this area was new to her but taught her the applications of physics at a much deeper level. Now a physicist at NIST, Cassie helps run calibration and measurement services related to magnetic resonance. Part of her work relates to phantoms — but not the ghost kind. These phantoms are scientific devices that serve as stand-ins for human tissue and are used in the biomedical research community as standard reference objects. Cassie’s calibrations involve the measurement of MRI biomarkers — quantitative parameters that indicate biological processes in the human body, such as tissue health. She measures these parameters in phantom materials, providing reference values used to verify the accuracy of MRI-based measurements. Her measurements have a well-defined uncertainty and are traceable to the International System of Units (SI), also called the metric system. MRI is conventionally a qualitative and nonnumerical tool, producing images that radiologists inspect to make a diagnosis. Cassie and her group work to advance the newer field of quantitative MRI, a numerical approach that offers more precise details on what the images show. #Physics #MedicalImaging #MRI #Measurement #EarlyCareer

Optical lattices – aka webs of light – trap atoms in a neat arrangement much like eggs in a carton. But what are they used for? ▪️ Creating next generation atomic clocks based on ytterbium or strontium atoms, which have higher precision in timekeeping. ▪️ Serving as flexible laboratories for cutting-edge basic research, such as quantum simulations that help researchers model complex quantum processes. ▪️ Offering a potential platform for quantum computers. Check out how NIST researchers are using these webs of light in their research: https://lnkd.in/gxXgmGrr 📸: G.E. Marti/JILA #Physics #Light #Frequency #Quantum

As we near the end of summer, cooler weather will soon be on its way, meaning the next flu season is near. But our bodies have a way of fighting off pathogens: neutralizing antibodies. NIST biologist Jerilyn Izac and her team are researching these antibodies using measurement science to see if in the future doctors can identify who would most benefit from getting a vaccine against an emerging virus.
