Optical Microscopy System Observes, Stimulates Multiple Living Cells
KOBE, Japan, Jan. 30, 2019 — A new optical microscope uses holographic techniques to stimulate multiple cells simultaneously and monitor cell activity after stimulation. Developed by researchers at Kobe University and called SIFOM for three-dimensional (3D) Stimulation and Imaging-based Functional Optical Microscopy, the system consists of two subfunctions: 3D observation of cells and 3D stimulation of cells based on digital holography. SIFOM can precisely stimulate user-defined targeted cells and simultaneously record the...

Photomultiplier Tubes from Brown Team Will Be the 'Eyes' of New Dark Matter Detector
PROVIDENCE, R.I., Jan. 25, 2019 — Brown University researchers have assembled two arrays of photomultiplier tubes (PMTs) to serve as the “eyes” for the LUX-ZEPLIN (L-Z) dark matter detector, which will begin its search for dark matter particles at the Sanford Underground Research...
CMOS Imaging: From Industry to Consumer and Back Again
Jan 25, 2019 — Technology often advances unnoticed. Incremental improvements may only be seen by insiders in industries that a technology already calls home. Sometimes it achieves a breakthrough point and whole societies can change as a result. This often happens...
Photoacoustic Approach Uses Lasers to Send Messages
LEXINGTON, Mass., Jan. 25, 2019 — Researchers from the Massachusetts Institute of Technology’s Lincoln Laboratory have demonstrated two laser-based methods to transmit various audio tones and recorded speech at a conversational volume to a person without any type of receiver...
All-Diamond Metamaterial Optics
Jan 24, 2019 — The strongly bound and tightly packed crystal lattice that comprises diamond makes it an ideal candidate for extreme optical and photonic devices. Thanks to the unique combination of its outstanding thermal, mechanical, and optical properties,...
Chalcogenide Aspherical Lenses in IR Imaging
Jan 24, 2019 — As the thermal imaging market continues to rapidly expand, a broad array of commercial applications has placed an increased emphasis on balancing cost and performance. While some still perceive conventional materials and manufacturing methods of...
