Researchers find gene that may be at root of potato blight
...in Wooster . "If you take a gun through the metal detector
at an airport, the alarms go off," he said. "This gene (Avr3a) sends a signal alerting the plant that it is infected by the pathogen." Phytophthora infestans is the pathogen that causes late blight. For decades, controlling this disease has involved...
New NIST method improves accuracy of spectrometers
...y-light signal for every element (or pixel) of the detector
array for every wavelength of light. The matrix then was used to correct the instrument's output signals for stray light. The method is simple and fast enough to be incorporated into an instrument's software to perform real-time stray-light correctio...
