Terrestrial Laser Scans Preserve New Zealand Tunnellers' Legacy
Jun 27, 2017 — Fifteen meters below the northern French city of Arras, researchers have been busy laser scanning a network of caves and tunnels to document and preserve New Zealand’s presence during World War I. More than 120,000 New Zealanders enlisted during the First World War, serving in battles such as Gallipoli, Messines, Passchendaele and Le Quesnoy. Of that group, 1308 men — the New Zealand Engineers Tunnelling Company — were given a highly secret mission to locate and connect
Light-Generated Bubbles Propel Microparticles, Create Optomechanical Force
BEER-SHEVA, Israel, June 27, 2017 — Energy created from light was converted into kinetic motion using nano-sized, laser-generated bubbles. As the bubble expanded, it acted as a propulsion mechanism for surrounding micron sized particles, propelling them at forces many times greater...
Light-Matter Interaction in Single Layer of Atoms

Light Augments Conventional Methods of Mosquito Control
NOTRE DAME, Ind., June 21, 2017 — Exposure to just ten minutes of white light presented at timed intervals during the late daytime, dusk, dawn and throughout the night could suppress biting and manipulate flight behavior in the Anopheles gambiae mosquito, the major vector for...
Multispectral Imaging Reveals Ancient Hebrew Inscription
TEL AVIV, Israel, June 20, 2017 — Multispectral imaging techniques have unearthed an invisible inscription on the back of a pottery shard that has been on display at The Israel Museum for half a century. The ostracon — ink-inscribed pottery shard — dates back to ca. 600...
Metamaterial-Enhanced Imaging Technique Could Reduce Acquisition Time
ST. PETERSBURG, Russia and LEIDEN, Netherlands, June 20, 2017 — A hybrid metasurface structure, comprised of a 2D metamaterial surface and a high permittivity dielectric substrate, has been shown to enhance the performance of an ultra-high field MRI scanner. The ultrathin structure could potentially be used to...
Novel Photopatterning Approach for OLEDs Inveiled
SANTA BARBARA, Calif., June 20, 2017 — A light-mediated methodology to growing patterned, emissive polymer brushes with micron feature resolution could lead to a more efficient, cost-effective method for creating OLED displays. Although many fabrication methods for OLEDs exist, they all...
AI Analyzes Images Taken Under Severe Conditions, Increases Clarity
TOKYO, June 19, 2017 — A multimodal image fusion technology uses artificial intelligence (AI) to automatically combine visible images taken by standard cameras with non-visible images taken by specialized devices such as thermal or terahertz cameras. Using AI, the...
Nanophotonic Processor Uses Optics to Speed Deep Learning Computations
CAMBRIDGE, Mass., June 16, 2017 — Using light instead of electricity to power neural networks could improve the speed and efficiency of certain deep learning computations, especially tasks that involve repeated multiplications of matrices, which can be computationally intensive for...
Novel Material May Allow Everyday 3D Holography
MELBOURNE, Australia, June 15, 2017 — What could be the world’s thinnest hologram could also be the harbinger of what’s to come in consumer electronics, by paving the way for 3D holography compact enough to be integrated into everyday electronics like smartphones, laptops...
Laser-Induced Graphene Inhibits Biofouling, Kills Bacteria
HOUSTON, June 14, 2017 — Laser-induced graphene (LIG) has been shown to be effective in resisting biofouling (the buildup of biological material on wet surfaces) and, when used as electrodes with a small applied voltage, in destroying bacteria. “This form of graphene...
Optical Approach Delivers Fast, Scalable Data Transmission
KARLSRUHE, Germany, June 14, 2017 — Microresonator soliton frequency combs have been shown to considerably increase the performance of wavelength division multiplexing (WDM) techniques in optical communications. The technology could be used to develop efficient, highly scalable...
Low-Cost Synthetic Material Produces White Light That Imitates Sunlight
TURKU, Finland, June 13, 2017 — Persistent luminescence materials are used in everyday glow-in-the-dark applications and show high potential for medical imaging, night-vision surveillance, and enhancement of solar cells. The materials that make these applications possible contain...
Underwater Touchpad Will Open Window Further Into the Dolphin Mind
NEW YORK, June 13, 2017 — An underwater computer touchscreen, through which dolphins at the National Aquarium in Baltimore, Maryland are able to interact, will be used to investigate dolphin intelligence and communication by providing the sea mammals with choice and control...

CLEMSON, S.C., June 13, 2017 — Two researchers at Clemson University are taking different but complementary approaches to creating a high-energy laser that could be used as a weapon. The engineers are receiving a combined $3.2 million from the Department of Defense to help fund...
Hybrid Imaging Method Delivers Panoramic Scan of a Live Animal
DURHAM, N.C., June 12, 2017 — A hybrid imaging technique, dubbed Single-Impulse Panoramic Photoacoustic Computed Tomography (SIP-PACT), combines light and ultrasound to provide a full cross-sectional view of a small animal’s internal functions in real time, with enough...
Photons and Electrons Produce Hybrid Light-Matter Fluid
MONTREAL, June 9, 2017 — Light is composed of waves, but it can also behave like a liquid. In certain circumstances it can ripple and spiral around obstacles. These liquid properties of light emerge when the photons that form the light wave interact with each other....
