The theme of Signal to Noise Magazine this month is Data December! As such, we've fashioned a relevant logo to help you spot our Data December pieces.
Pictured here is a heatmap, which is one way scientists represent data; a heatmap is essentially a data table, where the values of each cell are represented by colors. Scientists will often use this type of graph for data describing changes from a baseline or reference state - for example, whether a particular value is increasing or decreasing. A change of 0 (or a value matching the baseline) will be colored black or another central color, while values representing increases or decreases will be colored oppositely along a spectrum. Typically, this type of graph helps a viewer to easily identify trends in changes across lots of samples, since it simplifies data from numbers to colors. For example, in a study of what genes a group of cells is turning on and off, a heatmap can help to visualize groups of genes demonstrating the same patterns. A bright green cluster might represent genes with much lower expression than found in the baseline condition, while dull red cells identify genes with moderate increases in expression.
Look out for our heatmap this month - you'll find it next to articles with more Data December topics!
