Star Wars Meets Mosquito Control
JAMES SCHLETT, EDITOR
What does it take to kill a mosquito? How about thousands of them? Since 2010, Bellevue, Wash.-based Intellectual Ventures Management LLC has been working on answers to these questions. Their solution: the Photonic Fence, a laser system that optically tracks all flying insects that enter a coverage area and zaps only those identified as threats, namely mosquitoes. However, it was only recently that researchers identified the best combination of wavelength, power, pulse duration, pulse energy and beam diameter to efficiently kill the disease-spreading pests.

When the Camera Is a Computer: Computational Life Sciences Imaging
Sensors and cameras continue to progress, although life sciences imaging remains far from perfect. Even in its current state, barriers still exist. These include signal photon noise, light scattering, optical blur of finite aperture imaging systems and others. Versatile high-speed, high-resolution systems are overcoming these and other challenges, moving microscopy into a diagnostic role.

High-Content Screening Goes Beyond Fluorescent Pictures
Since the start of high-content screening (HCS) in the late 1990s, several imaging techniques have been applied for automated image capture, serving a variety of application goals and specifications. However, technological advancements are enabling HCS to cover new ground, particularly with confocal, bright-field and wide-field imaging.

Mirror-Enhanced Microscopy Provides New Info about Cell Behavior
A novel technique for growing cells on miniature mirrors and imaging them using super-resolution microscopy may provide a way to view cell structures at a micron scale. The technique uses light waves to create interference patterns as light passes through the cell on the way to the mirror, which reflects the light back through the cell.

Super-resolution and AFM Imaging
PicoQuant GmbH
The combination of atomic force microscopy (AFM) with time-resolved single-molecule-sensitive fluorescence microscopy in a single instrument opens up new avenues for fascinating investigations into the structure, dynamics, and interactions of single molecules or their assemblies in cells or tissue samples.
