Computer Tomography, Volumetric Imaging Reveal Details of Ancient Past
LINKÖPING, Sweden, Jan. 27, 2017 — Computer tomography (CT) scanning and volumetric visualization have been used to create a 3D display of the Geberlein Man, a 5,500 year-old natural mummy buried during the late pre-dynastic period at the site of Gebelein in Upper Egypt. Visitors to the Early Egypt Gallery at the British Museum can now interact with this display, even performing a virtual biopsy on the Gebelein Man in real-time with the touch of a hand. The technology allowing visitors to explore the Gebelein Man is an
Liquid Lens Paired With Infrared Light and a Smartphone Creates Smart Glasses
SALT LAKE CITY, Jan. 26, 2017 — Liquid-based lenses that automatically focus on what a person is seeing could replace reading glasses and bifocals in the near future. The human eye has a lens inside that adjusts the focal depth depending on what is being viewed. But as people age,...
Far-Infrared Cameras and Drones Turn Construction Vehicle Into Disaster-Relief Robot
OSAKA, Japan, Jan. 25, 2017 — A group of Japanese researchers have developed a prototype construction robot for disaster relief situations equipped with far-infrared ray cameras and the ability to deploy a drone. This prototype has drastically improved operability and mobility...
Transformation Optics Conceals Objects in Diffusive Environments
VALENCIA, Spain, Jan. 24, 2017 — Researchers have devised a new cloaking device that could conceal aircraft in fog or a submarine in the sea. Both the fog and the sea serve as diffusive environments in which light is not propagated in a straight line, which makes his cloaking...

Self-Assembling Particles Could Produce Lower Cost LEDs
PRINCETON, N.J., Jan. 19, 2017 — Self-assembling nanoscale perovskite — crystalline substances — particles could be a more efficient and lower-cost alternative material for LEDs.
3D Scans Help Automotive Industry Evaluate Data Aimed at Increasing Production Flexibility
WÜRZBURG, Germany, Jan. 16, 2017 — Today’s car factories are leaning towards having one production line suitable to manufacture frequent model changes and smaller volumes. This requires increased flexibility in production, more robots and a higher level of digitization. Andreas...
Squeezing Light Cools Microscopic Drum Below Quantum Limit
GAITHERSBURG, Md., Jan. 16, 2017 — Using a special circuit to generate microwave photons stripped of intensity fluctuations, physicists at the National Institute of Standards and Technology (NIST) have cooled a mechanical object to a temperature lower than previously thought...
Medical Imaging Innovator Christine Hendon Wins Presidential Honor
NEW YORK, Jan. 12, 2017 — Christine Hendon, assistant professor of electrical engineering at Columbia Engineering, has won the Presidential Early Career Award (PECASE), the highest honor the U.S. government gives to young scientists and engineers. Hendon develops innovative...
Compact Lasers Recreate Conditions Inside Stars
FORT COLLINS, Colo., Jan 12, 2017 — With compact lasers that use ultra-short laser pulses irradiating arrays of aligned nanowires, scientists are recreating the extreme conditions found in stars. Previously, this was only possible with large “stadium-sized” lasers, as the...
ASU Spectrometer to Fly on NASA Asteroid Mission
TEMPE, Ariz., Jan. 12, 2017 — A spectrometer developed by Arizona State University will fly onboard a NASA mission to Jupiter’s Trojan asteroids. The Lucy mission has been chosen under the agency's Discovery Program, a series of cost-capped exploratory missions into the...
Multi-Conjugate Adaptive Optics Device Offers Widest Real-Time Views of the Sun
BIG BEAR, Calif., Jan. 11, 2017 — A groundbreaking new optical device has been developed to correct images of the Sun previously distorted by multiple layers of atmospheric turbulence. The device developed at the New Jersey Institute of Technology’s (NJIT) Big Bear Solar...
Further Your Photonics Knowledge in 2017
PITTSFIELD, Mass., Jan. 10, 2017 — Advances in photonics occur daily, and the impact is felt across diverse industries and professions. One way to keep up with research and development in the field is through a Photonics webinar. Information-packed presentations by researchers,...
Plasmonic Nanolaser Opens the Way for Coherent On-Chip Light Sources
ESPOO, Finland, Jan. 9, 2017 — Using “dark lattice modes” researchers at Aalto University have created a plasmonic nanolaser that operates at visible light frequencies. The laser works at length scales 1000 times smaller than the thickness of a human hair. The results...
Imaging Technique Visualizes Individual Retinal Ganglion Cells
ROCHESTER, N.Y., Jan 5, 2017 — A new imaging technique that modifies confocal adaptive optics scanning light ophthalmoscopy (AOSLO) could revolutionize how eye health and disease are assessed. Using their new, non-invasive imaging technique, researchers at the University of...
Virtual Reality Diagnoses Balance Disorders
KAUNAS, Lithuania, Jan. 5, 2017 — Disorders of balance and vestibular function (balance and eye movement) can be diagnosed using a new portable, and inecpensive virtual reality device.
Robot with a Human Touch
ITHACA, N.Y., Jan. 4, 2017 — A soft robot has been created that can feel its surroundings internally, much like humans do. Using stretchable optical waveguides as curvature, elongation and force sensors in a soft robotic hand, researchers at Cornell University have overcome the...
Appalachian State Receives NSF Grant for Laser-Scanning Confocal Microscope
BOONE, N.C., Dec. 31, 2016 — Appalachian State University’s William C. and Ruth Ann Dewel Microscopy Facility received a $430,900 award from the National Science Foundation (NSF) to purchase a new state-of-the-art laser scanning confocal microscope (LSM). The new LSM will...
Univ. of Pitt, Ansys Receive NASA Grant
PITTSBURGH, Dec. 27, 2016 — Additive manufacturing (AM) researchers at the University of Pittsburgh's Swanson School of Engineering and simulation software company Ansys Inc. are among 13 university-led proposals to capture an Early Stage Innovations (ESI) grant from NASA's...
