Photonics Variety Spices Up the Sciences
JAMES SCHLETT, EDITOR
The British science historian Jacob Bronowski once pointed out that where Leonardo da Vinci was fascinated with nature's "variety, its infinite adaptability, the fitness and the individuality of all its parts," Isaac Newton, in contrast, found great pleasure in astronomy because of "its unity, its singleness, its model of a nature in which the diversified parts were mere disguises for the same blank atoms." However, despite his affinity for unity, Newton would doubtlessly be impressed with the variety of photonics technologies for which his theories on light laid the foundation in the 17th century.

Beyond OCT: New Interferometric Imaging Techniques in Biomedicine
Optical coherence tomography (OCT) began its commercial history in 1996 as a revolutionary technology for imaging retinas to help diagnose eye diseases, including glaucoma, macular degeneration and diabetic retinopathy. Now a mainstay in ophthalmology offices, OCT technology has expanded its reach to numerous other biomedical applications, including cardiology, IVF and oncology.

Biophotonics-Related Companies' FY2015 R&D Spending Growth Loses Steam
Research and development spending at many biophotonics-related companies failed to keep pace with revenue growth in their 2015 fiscal years, according to analysis of financial reports issued by 20 publicly traded companies and tracked by Photonics Media for this new quarterly column.

Optogenetics Shows Promise in Treatment of Chronic Pain
Optogenetics may someday provide doctors with a noninvasive, highly focused way to treat chronic pain. By making the cells responsible for pain transmission sensitive to light, the technique may be able to target, desensitize and reduce bioelectric activity in these cells.

A technique based on optical interferometry could enable ultrasonic methods to be used internally to gather information about the heart tissue. Until now ultrasonic methods have only been used externally, because the piezo electronical components necessary for internal use have not been sufficiently miniaturized to be inserted into the blood vessels.

An experimental optogenetics technique has been applied to a mouse model of Alzheimer's disease to rescue memories. The study revealed that spines — small knobs on brain-cell dendrites through which synaptic connections are formed — are essential for memory retrieval and that fiber optic light stimulation could be used to regrow lost spines, enabling the mice to remember a previous experience.

Digital Conference:
Photonics for Ophthalmology
Thu, Jun 9, 2016 12:00 PM - 3:15 PM EDT
Photonics Media invites you to join us for our upcoming digital conference, "Photonics for Ophthalmology." The event will feature several 15-minute online presentations on the use of light-based imaging and surgical techniques for diagnosing and treating eye conditions. Brief question-and-answer sessions will follow each presentation. Presentation topics include photo-mediated ultrasound therapy, ophthalmologic lasers, intraocular lenses, photobiomodulation and various aspects of optical coherence tomography.
