Application of Atomic Force Microscopy (AFM) to a broad range of research, and biological systems in particular, is hampered by two longstanding technical problems: mechanical drift and finding sparsely distributed samples. By adapting ideas from the optical-trapping community, we have made significant progress in addressing both of these issues, including a 100-fold improvement in the stability of AFM at ambient conditions.

Designed to record bursts of images at an unprecedented speed of 4.5 million frames per second, an innovative X-ray camera being built with STFC's engineering expertise will help a major new research facility shed light on the structure of matter. The device will be delivered to the European XFEL (X-ray Free-Electron Laser) next year and will contribute to drug discovery and other vital research once this facility starts operating in 2015.

Newport reported it has entered into an agreement to acquire High Q Technologies, a developer and manufacturer of ultrafast lasers. Terms of the transaction, which is anticipated to close before the end of the third quarter, were not disclosed. High Q, headquartered in Rankweil, Austria, expects 2011 revenues of approximately US-$ 20 million, with threefourths of its sales to customers in Europe.

Most experiments need to be repeated at least three times for data accuracy and statistical significance. Whether you are using a lamp system, LED or laser source, measuring the illumination power is a critical step in ensuring consistent conditions. In this short video presentation, Dr. Kavita Aswani is introducing a power measurement system enabling consistent and repeatable illumination throughout research experiments.

Since their discovery in 1896 , x-rays have fundamentally revolutionized science, medicine and technology. Each successive generation of x-ray machines has opened up new frontiers in science, such as the first radiographs and the determination of the structure of DNA. State-of-the-art x-ray sources, such as synchrotrons, can now produce coherent high-brightness beams of x-rays with energies greater than kiloelectronvolt, which promise a new revolution in imaging complex systems on the nanometer and femtosecond scale.

It sounds like something out of a comic book or a science fiction movie - a living laser - but that is exactly what two investigators at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed. Wellman researchers Malte Gather, PhD, and Seok Hyun Yun, PhD, describe how a single cell genetically engineered to express green fluorescent protein (GFP) can be used to amplify the light particles called photons into nanosecond-long pulses of laser light.

With the most recent introduction of a new multi-wavelength excitation-laser coupling unit WITec has further advanced the ease-of-use of its microscope series. It is now possible to switch between up to three laser sources by the simple rotation of a filter wheel. Calibration and alignment of the laser beam path is guaranteed at all positions assuring accurate and variable Raman Imaging. Each excitation wavelength features a high-quality and wavelength optimized filter set, enabling the highest throughput and contributes to the speed and sensitivity of WITec's systems.
