Dry Eye Symptom Screens Show Modest Accuracy
In head-to-head comparisons, two of five dry eye screens showed a statistically significant ability to detect signs of the disorder, but all demonstrated relatively modest diagnostic accuracy, researchers say. Reuters Health Information
Cheap Infrared Scanners Thanks to Quantum Effects and Wavelength Shifts
Infrared spectroscopy is commonly used for testing the strength of various materials, to study archaeological finds, and in forensics. It’s a bit of a niche in medicine, partially due to the fact that the visible spectrum is itself so useful and equipment relying on it cheap to acquire. Researchers at the Agency for Science, Technology [&hell (Read more...)
