Noninvasive Optical Sensors Provide Real-Time Brain Monitoring After Stroke
Each year, nearly 800,000 people in the U.S. experience a stroke, and almost 90 percent of those are ischemic strokes in which a clot cuts off blood flow to part of the brain. To prevent further injury, blood flow to the brain must be restored as quickly as possible. In a new study, researchers show that non-invasive optical sensors can provide clinicians with real-time feedback on whether clot busting treatments are restoring blood flow. The technique, which monitors blood flow and oxygen levels in the brain, could also reveal early warnings signs of neurological complications after a stroke.

The Optical Society Launches Updated Optics4Kids Website
Today, The Optical Society (OSA) has launched its redesigned youth education website, Optics4Kids.org, which seeks to provide comprehensive optics and photonics resources for kids, pre-college students, educators and parents. OpticsForKids.org has numerous activities and features such as an optics timeline, optical illusions, a career assessment tool, experiments for children of all ages and much more. The latest website updates include a fresh design and an “Ask A Scientist” feature.

Powerful LED-Based Train Headlight Optimized for Energy Savings
Researchers have designed a new LED-based train headlight that uses a tenth of the energy required for headlights using conventional light sources. If operated 8 hours every day, the electricity savings of the new design would reduce emissions of the greenhouse gas carbon dioxide by about 152 kilograms per year.

Statement from The Optical Society on the FY 2019 Budget Proposal from the Trump Administration
The Optical Society (OSA) issued the following statement on the release of President Donald Trump’s proposed fiscal year 2019 budget. Proposed cuts to the National Institute of Standards and Technology (NIST), the Advanced Research Projects Agency at the Department of Energy (ARPA-E) and other agencies would negatively impact the United States’ role as a leader in scientific innovation. The funding for certain science-related agencies, such as the National Science Foundation (NSF) and the Office of Science at the Department of Energy (DOE), wouldn’t increase but be held at current levels.

The Optical Society Mourns the Loss of Frances Hildreth Townes
In 1951, Charles Townes conceived the idea of the maser, a laser precursor, while sitting in a park one sunny morning in Washington D.C., and a few months later he began building it, using ammonia gas as the active medium. Townes and his colleagues coined the word "maser" for this device, which is an acronym for microwave amplification by stimulated emission of radiation. OSA Fellow Charles Townes received the Nobel Prize in 1964 for discovering the principles behind the laser, the practical applications of which altered the way we communicate daily.

Researchers Create Fiber Optic Sensors that Dissolve in the Body
For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for in-body monitoring of bone fracture healing and for safer exploration of sensitive organs such as the brain.

New Use for Telecommunications Networks: Helping Scientists Peer into Deep Space
For the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometers over a standard fiber optic telecommunications network and used to synchronize two radio telescopes. Stable frequency references, which are used to calibrate clocks and instruments that make ultraprecise measurements, are usually only accessible at facilities that generate them using expensive atomic clocks.

OIDA Workshop on Scalable Integrated Photonics for 5G and Sensor
Fifth generation (5G) wireless and the Internet of Things (IoT) are introducing a wide range of new applications that will depend on performance enhancements across multiple dimensions, including low latency, high capacity, and enhanced resilience. The OIDA Workshop at OFC will be held 11 March in San Diego, California. This workshop will examine this opportunity for integrated photonics to provide capacity and latency that can meet the demanding requirements of 5G and IoT applications through plenary and invited talks by leading experts in the field.
