Optical images produced in sequences, or even movies, can provide many fine details about cell dynamics. Edward S. Yeung of Ames Laboratory and Iowa State University discusses how to gain the same detailed information using the intrinsic fluorescence of a naturally occurring cell component. 531 A A Sensing System for Odor Plumes. There are numerous strategies for sensors to detect various chemical signals, but how those chemicals are transported in air or water has received little attention. 538 A The Weakest Link Exercise.
Analytical data are only as good as a method's least precise operation.
A Analytical Currents Quicker than thieves. ISA assay for retroviruses. Helicobacter pylori biomarkers. High power play. SIMS of cellular membranes.
