New Mobile Health Tool Measures Hemoglobin Without Drawing Blood
Researchers have developed a way to use smartphone images of a person’s eyelids to assess blood hemoglobin levels. The ability to perform one of the most common clinical lab tests without a blood draw could help reduce the need for in-person clinic visits, make it easier to monitor patients who are in critical condition, and improve care in low- and middle-income countries where access to testing laboratories is limited.

Laser-Based Technique Captures 3D Images of Impressionist-Style Brushstrokes
Researchers have developed a new strategy that uses optical coherence tomography (OCT) to acquire both the surface and underlying details of impressionist style oil paintings. This information can be used to create detailed 3D reconstructions to enhance the viewing experience and offer a way for the visually impaired to experience paintings.

OSA Statement on the Coronavirus Aid, Relief and Economic Security (CARES) Act
With the impact of COVID-19 (Coronavirus) disrupting important scientific research that could lead to new discoveries and technologies to combat the pandemic, the Coronavirus Aid, Relief and Economic Security (CARES) Act approved by the U.S. Congress provides critical resources to the optics and photonics community. Across the globe, researchers are racing to develop vaccines and therapeutics to contain the spread of the virus. This infusion of U.S. government funds to science agencies and research institutions will accelerate studies and testing capabilities, increasing our knowledge of the disease and improving treatment options.
