BioTuring has recently launched their Big Data Portal. This enables scientists worldwide to connect to their server and analyze in real time the largest collections of single-cell datasets. With a lot of engineering effort (100X in speed improvement of gene marker finding algorithm, data compression, improvement in sparse matrix read/write, scatter plot visualization, etc.), this for the first time allows scientists to perform real time analysis and visualization on millions of cells. All you need is a normal laptop and BioTuringBrowser to connect to the portal. Access is free during the lockdown.
