 E-Mail A new software tool allows researchers to quickly query datasets generated from single-cell sequencing. Users can identify which cell types any combination of genes are active in. Published in Nature Methods on 1st March, the open-access 'scfind' software enables swift analysis of multiple datasets containing millions of cells by a wide range of users, on a standard computer. Processing times for such datasets are just a few seconds, saving time and computing costs. The tool, developed by researchers at the Wellcome Sanger Institute, can be used much like a search engine, as users ...

Nanotechnology Now Home > Press > How photoblueing disturbs microscopy Confocal fluorescence images of glass surfaces coated with the cyanine dyes Alexa Fluor 647 (a) and CF660C (b) and with carborhodamine dye ATTO647N (c) after light excitation at 568 nanometres (nm). By exciting the red-absorbing dyes at 640 nm in certain areas (negative images top right), dyes are photoconverted there and it is possible to write letters on the surface that were excited at 568 nm and fluoresce at about 580 nm. The carborhodamine dye shows more efficient photobluing than the cyanine dyes. CREDIT Team Markus ...

However, under certain circumstances, an effect occurs that falsifies the results: the laser light used can cause very reactive oxygen ...

These alternative RNA 'shapes' can have important functional relevance in viruses and bacteria. The res...
