FEATURES
A Brighter Red, a Simpler Green and Structural Understanding Fluorescent proteins are essential tools for probing and understanding biochemical processes as they happen. And as any mechanic or handyman knows, you have to have the right tool for the job. That is why research into the development of new fluorescent proteins continues and is so important. A look at the efforts of three groups shows that some of the latest advances involve a new and brighter...
Engineer-Physician Collaboration Model Aids Biophotonics in Medicine The direct application of engineering to medicine is a notable trend of the past decade. Noninvasive diagnostic technologies, high-resolution imaging, advanced materials implants and...
Optical Coherence Tomography Aids Cancer Detection Optical coherence tomography (OCT) has been applied successfully in ophthalmology since the early 1990s, a success story triggering research efforts in the imaging of early epithelial cancers....
OCT Could Enable Noninvasive Diabetes Monitoring The majority of diabetes patients must prick themselves several times a day to monitor their glucose level. They then self-administer insulin or medication to ensure that their level remains within...

POST SCRIPTS
Fine features of fruit fly captured in 3-D Scientists seeking to crack the mysteries of Alzheimer’s and other diseases that attack the human brain continue to look at the fruit fly for possible clues. The Drosophila melanogaster fruit fly and humans share many genes with similar functions, and the insect is frequently used in research to study how genes influence disease. This 3-D image of a fruit fly was generated using optical...
