New approach strengthens negative refraction
CAMBRIDGE, Mass. – An “extraordinarily strong” negative refractive index as large as -700 – more than 100 times larger than most previously reported – has been achieved in metamaterials using a technique developed by scientists at Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with Weizmann Institute of Science in Israel. In a vacuum, light travels so fast that it can circle the Earth more than seven times in the blink of an eye. When light propagates through ...
Scanning Goniophotometers Improve Materials Selection

LA JOLLA, Calif., Sept. 20, 2012 — Bjorn Lillemeier and Axel Nimmerjahn of the Waitt Advanced Biophotonics Center will each receive $1.5 million from the National Institutes of Health as two of only 51 recipients of the award that recognizes visionary scientific efforts.
Thousands of Cells Tracked Via Lensless Imaging
LOS ANGELES, Sept. 18, 2012 — A novel lensless computational imaging platform is being touted as a new way to observe and track large numbers of rapidly moving objects under a microscope, capturing precise motion paths in three dimensions. For the first time, the 3-D helical...
Plasmon Wave Propagates for 80 µm with No Diffraction
CAMBRIDGE, Mass., Sept. 7, 2012 — A needle-like beam of light that propagates for an unprecedented distance of 80 µm without spreading could greatly reduce signal loss for on-chip optical systems. The cosine-Gauss plasmon beam, caused by quasiparticles called surface plasmons,...
Spectroscopy Optimizes Fluorescent Probes for DNA Study
HOUSTON, Sept. 7, 2012 — Time-resolved spectroscopy plus careful calculations can optimize photoluminescent probes for studying DNA, with results nearly twice as good as standard fluorescence spectroscopy for specific sequences, according to a new paper from Rice...
WITec Opens Offices in Japan and Spain
ULM, Germany, Sept. 4, 2012 — Rapid growth in Europe and Asia has spurred nanoanalytical microscopy systems maker WITec GmbH to open regional offices in Japan and Spain.

Portrait of a single atom
BRISBANE, Australia – The shadow of a single atom was photographed for the first time using a superhigh-resolution microscope, a discovery that could help scientists confirm their understanding of atomic physics and advance quantum computing. “We have reached...
White LEDs grown on paper
LINKÖPING, Sweden – Imagine a room with wallpaper that lights up with the touch of a hand. A zinc oxide and polymer solution could soon make this dream a reality by allowing LEDs to be grown directly onto the surface of paper, or even printed onto wallpaper like ink. ...
Merging Microscopy Methods Sharpens Brain Imaging
SESTO FIORENTINO, Italy, Aug. 28, 2012 — Technology that combines the best features of two microscopy methods yields images 100 percent sharper than those acquired through conventional light-sheet-based microscopy (LSM).
Microscope Addresses the Need for Speed
LEICESTER, England, Aug. 28, 2012 — A technology used in projectors can create a high-resolution image 100 times faster than conventional microscopy equipment, which can be too slow to clearly document speedy biological processes.
Lasers for Standoff Sensing Improved
EVANSTON, Ill., Aug. 27, 2012 — A new resonator design that controls both wavelength and beam quality enables the purest, brightest, and most powerful beams ever from a single-mode infrared quantum cascade laser. The work improves the accuracy of the devices, critical for boosting...
