A Faster Single-Pixel Camera Opens Up New Possibilities for Industrial Lensless Imaging
CAMBRIDGE, Mass., April 3, 2017 — Compressed sensing is a new computational technique for extracting large amounts of information from a signal. Researchers at Rice University built a camera that could produce 2-D images using only a single light sensor rather than the millions of light sensors found in a commodity camera. The problem though, was that this single-pixel camera needed thousands of exposures to produce a fairly clear image. Now, the Massachusetts Institute of
Smartphone-Based Assay Can Detect Male Infertility
BOSTON, April 3, 2017 — A smartphone-based device for point-of-care male infertility screening has demonstrated the ability to detect sperm concentration and motility with 98 percent accuracy. The smartphone-based assay is easy to use and can be performed at home or in a...

Bach to Supply NIRPS Gratings
BOULDER, Colo., March 30, 2017 — Custom diffraction grating manufacturer Bach Research Corp. has been awarded a contract by the NIRPS (Near Infrared Planet Searcher) consortium to manufacture and deliver a custom R4 echelle grating and spares that will be used in the NIRPS...
Nanoscale Sensor Detects Disease
SYDNEY, March 28, 2017 — A new nanoscale sensor has been developed that can help detect cytokines — molecules that play a critical role in cellular response to infection, inflammation, trauma and disease. Researchers at the Australian Research Council Centre of Excellence...
Optical Metamaterials Use III-V Semiconductors as Building Blocks
ALBUQUERQUE, N.M., March 28, 2017 — Materials that are more efficient than metals and that feature wider bandgap measures than silicon are being developed for possible use in optical metamaterial applications. All-dielectric materials using III-V semiconductors could be used to...
Nanoparticle Crystal Used to Control Light
EVANSTON, Ill. and ANN ARBOR, Mich., March 27, 2017 — A complex clathrate colloidal crystal has been created by connecting nanoparticles using DNA. One potential application for the novel crystal structures is the control of light.
fNIRS Tool Measures Brain’s Response to Acute Pain
BELLINGHAM, Washington and CARDIFF, U.K., March 27, 2017 — Functional near-infrared spectroscopy (fNIRS) — an optical imaging tool for monitoring regional blood flow and tissue oxygenation — is being explored as an option to track the brain's response to acute pain in adults and infants. Researchers from...
Terahertz Analysis Helps Target Measures for Controlling Pollution
BEIJING, March 24, 2017 — A combination of terahertz (THz) absorption and 2D correlation spectroscopy (2DCOS) has been used to identify the concentration and pollution sources of PM2.5 (particulate matter less than 2.5 µ in diameter) in the Beijing-Tianjing-Hebei...
IR Light Remotely Controls Curvature of Plastics
RALEIGH, N.C., March 24, 2017 — A new technique has been developed that uses infrared light to curve 2D plastic sheets into 3D structures such as spheres, tubes, or bowls. Researchers at North Carolina State University are building on previous research that focused on self-folding...
