Research & Technology News
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 technology possible. Researchers at the Valencia Nanophotonics Technology Center and The Public University of Navarre (NUP) have simulated this new invisibility cloak and lead researcher, Bakhtiyar Orazbayev said they will soon begin building

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...
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...
Winship Installs Lattice Sheet Microscope
ATLANTA, Jan. 6, 2017 — The Winship Cancer Institute at the Woodruff Health Sciences Center at Emory University became one of only 15 sites worldwide to receive a lattice sheet microscope. Different than conventional microscopy, lattice light sheet microscopy allows...
Optogenetics Platform Uses Light to Activate Control of Intracellular Phase Transitions
PRINCETON, N.J., Jan. 6, 2017 — A novel optogenetics platform, dubbed optoDroplet, uses light to activate phase transitions inside living cells. The optoDroplet system is being used to study the condensed phases driven by intrinsically disordered protein regions (IDRs). Its use...
Ultra-Hard Material Cutting Machines Market to Reach $1.81B
ALBANY, N.Y., Jan. 6, 2017 — The global ultra-hard material cutting machines market was valued at $730 million in 2015, according to a research report released by Transparency Market Research, and is expected to reach $1.81 billion by 2024. The firm says the global ultra-hard...
