Diagnosing Disease with Raman Spectroscopy
Vibrational spectroscopic techniques such as Raman spectroscopy have taken on increasingly important roles in point-of-care testing, spectral histopathology, and rapid in vivo diagnostics. Nick Stone is a Professor of Biomedical Imaging and Biosensing at the University of Exeter, and he and his group use Raman spectroscopy for measuring changes in the molecular constituents of cells and tissues as disease develops. He recently spoke to us about this work. |

Statistics, Part I: First Foundation
Modern statistics rests on three foundational principles. Here, we explain the first of these. But instead of getting involved in the nitty gritty of the equations, we approach this topic from the top down, concentrating on the core principles that apply to all major aspects of the use and application of statistical thought. |

| App of the Month |
 |
SpectroCalc
The SpectroCalc app is designed for conversion of units that describe electromagnetic waves. According to the company, the user interface features three columns. The left and center columns are simple converters of wavelength, wavenumber, energy, and frequency. The right column calculates difference between values in the left and center columns, or can be used to calculate either the left or center column if one of these is left blank. |
