Science Daily October 13, 2021 A team of researchers in the US (Harvard University, Northwestern University) has shown that digital data can be stored in mixtures of fluorescent dye molecules, which are deposited on a surface by inkjet printing, where an amide bond tethers the dye molecules to the surface. A microscope equipped with a multichannel fluorescence detector distinguishes individual dyes in the mixture. The presence or absence of these molecules in the mixture encodes binary information (0 or 1). The use of mixtures of molecules, instead of sequence-defined macromolecules, minimizes the time and difficulty of synthesis and eliminates the […]

Racing Toward Yottabyte Information
IEEE Spectrum June 26, 2019 The highest prefix in the international system of units is yotta, Y is 10 to the power of 24. We’ll have that many bytes within a decade. And once we start creating more than 50 trillion bytes of information per person per year, will there be any real chance of making effective use of it? It is easier to find new prefixes for large databases than to decide how large is large enough. After all, there are fundamental differences between accumulated data, useful information, and insightful knowledge…read more.
New data science method makes charts easier to read at a glance
Science Daily October 18, 2018 A team of researchers in the US (Columbia University, Tufts University) has developed a new method — “Pixel Approximate Entropy” — that measures the complexity of a data visualization and assigns a “visual complexity score”. The system automatically simplifies or summarizes charts that would be hard to read on their own. They modified a low dimensional entropy measure to operate on line charts, and then conducted a series of user studies that demonstrated the measure could predict how well users perceived charts… read more.
