Editorial
Question the narrative. Narrate the questions. On May 7, a horse named Rich Strike entered Churchill Downs’ starting gate as an 80-1 long shot in the Kentucky Derby. During the hour prior to that moment, media commentators, statisticians, and racing industry experts all shared in exhaustive and breathless detail the pedigree, training regimens, and racing history of all the favored horses to watch that day. For the 60 minutes prior to...

EPIC Insights
Photonics Brings Laboratory Analysis and Insights to Cultural Conservation The use of lasers for art conservation was pioneered by American research physicist John Asmus, who, in 1972, first leveraged lasers to clean marble sculptures in Venice without harming the underlying works. Over the next 30 years, Asmus further introduced the use of holography, ultrasonic imaging, digital image processing, and nuclear magnetic resonance to art conservation practices. Applying...
