iF Design Awards 2016 / Awards / News / Sony Design / Sony

Jury Statement: People love design for sound reproduction, especially if it’s easy to deploy and to pack away again. Designers know well how difficult it is to mate together different materials of similar color, and one of the great challenges in product design is successfully combining two synthetic materials and adding some metal into the …

4Pi-RESOLFT Nanoscopy

By enlarging the aperture along the optic axis, the coherent utilization of opposing objective lenses (4Pi arrangement) has the potential to offer the sharpest and most light-efficient point-spread-functions in three-dimensional (3D) far-field fluorescence nanoscopy. However, to obtain unambiguous images, the signal has to be discriminated against contributions from lobes above and below the focal plane, …

MyScope for Global Research Training

Each module contains a virtual machine that provides the functional environment encountered when using such equipment in a laboratory. Exploration has the safety of a virtual platform and comfort of guided instruction. The use of real images enhances the experience and allows an element of discovery beyond the mechanistic. Modules contain text, interactive graphics, flowcharts …

Image gallery: Life Science Imaging with the Leica DVM6 Digital Microscope

Digital microscopes were originally designed for industrial quality control applications. With images transferred directly onto a screen or PC monitor, digital microscopy transforms the microscopy workstation to a PC workplace. Digital microscopy has applications in inspection, documentation, and analysis. The fields of applications for digital microscopes have become more numerous since their introduction. Even life …

The Impact of a Stable Red Reflex and Enhanced Focus in Cataract Surgery

Ike Ahmed: One of the challenges with visualization is enhancing the red reflex particularly during phacoelmusification, cataract extraction and also during the intraocular lens surgery. The red reflex gives us the ideal contrast as well as the important depth in terms of where we are working within the eye. So one of the important …

Cryo-electron Microscopy of Tubular Arrays of HIV-1 Gag Resolves Structures Essential for Immature Virus Assembly

HIV-1 undergoes a two-step assembly process. First, an immature noninfectious particle is assembled, which leaves the infected cell. Second, the structural protein, Gag, is cleaved in the virus by the viral protease, and this leads to formation of the infectious virus. The immature virus particle therefore represents the key intermediate in HIV-1 assembly. There is …

Infection of Zebrafish Embryos with Intracellular Bacterial Pathogens

Transparent zebrafish embryos have proved useful model hosts to visualize and functionally study interactions between innate immune cells and intracellular bacterial pathogens, such as Salmonella typhimurium and Mycobacterium marinum. Micro-injection of bacteria and multi-color fluorescence imaging are essential techniques involved in the application of zebrafish embryo infection models. Source link
