Editorial
An unprecedented view of the origins of disease Photoacoustic microscopy is allowing researchers and clinicians an unprecedented view — based on the technique’s ability to reveal information about the circulation of cells throughout the body — of the origins of disease. It is also opening a window into the innate abilities of animal species to adapt to their environments. For example, photoacoustic microscopy has revealed the...

3 Questions with Dr. Donald Patthoff BioPhotonics spoke with Dr. Donald Patthoff, who practices general dentistry in Martinsburg, W.Va., and is editor of the Journal of Laser Dentistry and co-author of the book Dental Ethics at Chairside: Professional Obligations and Practical Applications. Patthoff is also the co-founder and co-director of the Foundation for Photobiomodulation Research (PBM Foundation). He discusses the need to...
BioOpinion
Priorities differ in industry and academia Most scientists work either in academia or in business. The cultural differences between the academic and business environments in the photonics community can be boiled down to some basic concepts that the scientist must consider when choosing what course his or her career path will take. Common to both environments is the need for integrity — for words, actions, and expectations to be internally...

Insect preference drawn from the color wheel People often make dietary choices based on visual appeal. But this is basic instinct for insects. While insect species may not interpret their surroundings by sight in the same way that humans do, insects do use their eyes to gather information about survival — including visual color cues about what looks good to eat. Aphids, for example, are notorious for feasting on vital crops in agricultural...
