Researchers at the National Institute of Standards and Technology (NIST) have developed a new statistical tool that they have used to predict protein function.
The natural, or resonance, frequency at which a simple harmonic oscillator vibrates reveals with exquisite sensitivity the essential properties of the physical
DNA is not only the blueprint of life; it has become the backbone for making tiny structures that can be inserted into the human body to diagnose and treat
Atomic clocks are key to a wide array of technologies and scientific experiments, including tests of fundamental physics. Clocks operating at optical frequencies have now demonstrated fractional stability and reproducibility at 10 -18, two orders of magnitude beyond their microwave predecessors
Corrosion impacts a broad spectrum of application areas including infrastructure, transportation, and the military. The annual price tag for corrosion mitigation and remediation is 3.4 % of the US GDP. The team is particularly interested in discovering new metallic glasses (metals without long range
Starting in 2015, SED staff members began reviewing published literature on the recommended practice for forensic examiners to provide likelihood ratios (LRs) as a weight of evidence to summarize their findings in reports or testimony. While several stated motivations for providing likelihood ratios
