EMCCD Camera

Andor Technology, South Windsor, CT, has released the iXon X3 range of electron multiplying charge coupled device (EMCCD) cameras. The OptAcquireTM interface allows users to single-click various camera acquisition parameters. The device also offers Count Convert functionality, providing real time data acquisition in units of electrons or incident photons. Additional new features include spurious noise filters, a cropped sensor mode to boost frame rates, photo counting capabilities, and real-time data averaging.

Isolation of the Paenibacillus phoenicis, a Spore-Forming Bacterium

A microorganism was isolated from the surfaces of the cleanroom facility in which the Phoenix lander was assembled. The isolated bacterial strain was subjected to a comprehensive polyphasic analysis to characterize its taxonomic position. Both phenotypic and phylogenetic analyses clearly indicate that this isolate belongs to the genus Paenibacillus and represents a novel species.

Cell Radiation Experiment System

Cells can be irradiated under conditions that approximate those in living tissues.The cell radiation experiment system (CRES) is a perfused-cell culture apparatus, within which cells from humans or other animals can (1) be maintained in homeostasis while (2) being exposed to ionizing radiation during controlled intervals and (3) being monitored to determine the effects of radiation and the repair of radiation damage. The CRES can be used, for example, to determine effects of drug, radiation, and combined drug and radiation treatments on both normal and tumor cells. The CRES can also be used to analyze the effects of radiosensitive or radioprotectant drugs on cells subjected to radiation. The knowledge gained by use of the CRES is expected to contribute to the development of better cancer treatments and of better protection for astronauts, medical-equipment operators, and nuclear-power-plant workers, and others exposed frequently to ionizing radiation.

Monolithically Integrated, Mechanically Resilient Carbon-Based Probes for Scanning Probe Microscopy

These probes can be used in medical applications for bacteria or protein imaging.Scanning probe microscopy (SPM) is an important tool for performing measurements at the nanoscale in imaging bacteria or proteins in biology, as well as in the electronics industry. An essential element of SPM is a sharp, stable tip that possesses a small radius of curvature to enhance spatial resolution. Existing techniques for forming such tips are not ideal. High-aspect-ratio, monolithically integrated, as-grown carbon nanofibers (CNFs) have been formed that show promise for SPM applications by overcoming the limitations present in wet chemical and separate substrate etching processes.

Imaging Technology Enables 3D Monitoring for Surveillance and Missile Defense

A new imaging technology can quickly give users accurate three-dimensional depictions of objects being tracked, whether they are incoming missiles or the faces of suspects in a crowd. The technology, being developed by Visidyne of Burlington, MA, has numerous applications beyond missile defense. The Missile Defense Agency (MDA) originally funded the company through a 2003 Small Business Innovation Research (SBIR) Phase II contract.

Graphics Adapter Board

Matrox Imaging, Dorval, QE, Canada, has introduced the Orion HD graphics adapter with video capture capabilities. It features two independent video paths; each path can connect and switch between RGB/CVBS/YPrPb, DVI-D/HDMI, and SDI signal types through DVI-D and BNC connectivity. It can handle different resolutions and rates including SD, HD, PC, and non-standard. It includes a programmable color space converter for obtaining accurate color representation of the original image. Video outputs are independent of each other as well as independent from the video inputs.
