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.

Human error accounts for more than 80% of cyberattacks. But many organizations fail to address human error when designing their cybersecurity procedures. A NIST summer intern researched the role that human error, such as weak passwords, plays in cyberattacks. His research may help organizations better protect their networks.

NIST is offering updated guidance on a wide range of methods people use to prove their identity, from digital wallets and passkeys to physical IDs. The guidance aims to ensure security, privacy and accessibility during the identity-proofing process while accessing government services. This second draft is intended to make access to online services both secure and straightforward, regardless of how a person chooses to prove their identity. NIST is seeking public comment on the draft guidelines by Oct. 7, 2024.

You most likely have heard the term greenhouse gas. They’re gases that trap heat in the atmosphere, and they consist of many different types of molecules from carbon dioxide to methane. But how do scientists measure these invisible and odorless gases? Turns out these greenhouse gases absorb specific colors of light, creating unique “fingerprints” that are used to detect them in the atmosphere. Scientists can figure out the exact concentration of a specific gas by studying the light that has passed through air and measure how much light is missing at colors uniquely absorbed by that gas.

Accessibility comes in many forms, such as providing alt text or descriptive text of an image on a website, or generally making information more accessible to a larger audience. For NIST intern Theresa Thomas, she’s helping with the latter. A recent college graduate from William & Mary, Theresa is spending her summer at NIST as part of NIST’s Summer Undergraduate Research Fellowship Program, or SURF. During her time at NIST, she’s helping with work on a registry database focused on the circular economy — an economy in which materials are designed to retain their value through repeated reuse, repair and recycling, with disposal as a last resort. The registry is a database of resources about sustainability, circularity and recycling that will help anyone working on circular economy research. Theresa’s task is to help put resources that have already been identified into the database and tag them with keywords and add metadata. She also helps find bugs in the database by serving as a fresh set of eyes. The database is still in development and in the beta phase but will be useful for not just researchers in this field but individuals outside of it such as policymakers, academics and those in the broader field of industry. “During this development stage of the registry, I’m at a place where my input makes a difference in how people will use the registry and access these resources. I want it to be accessible to people from the public at large to subject matter experts. My goal is to make the content understandable and the search engine easier so people can find the research they’re specifically looking for.” #Accessibility #Database #Data #CircularEconomy
