PDB-101: Goodsell Gallery: Coronavirus Coronavirus, 2020 This painting depicts a coronavirus just entering the lungs, surrounded by mucus secreted by respiratory cells, secreted antibodies, and several small immune systems proteins. The virus is enclosed by a membrane that includes the S (spike) protein, which will mediate attachment and entry into cells, M (membrane) protein, which is involved in organization of the nucleoprotein inside, and E (envelope) protein, which is a membrane channel involved in budding of the virus and may be incorporated into the virion during that process. The nucleoprotein inside includes many copies of the N (nucleocapsid) protein bound to the genomic RNA. For more information about coronavirus, visit the February Molecule of the Month on coronavirus proteases. There are also many structures of coronavirus proteins in the PDB archive; search for "coronavirus" at the main PDB site to see them.

20+ Tools to Create Your Own Infographics A picture is worth a thousand words – based on this, infographics would carry hundreds of thousands of words, yet if you let a reader choose between a full-length 1000-word article and an infographic that needs a few scroll-downs, they’d probably prefer absorbing information straight from the infographic. What’s not to like? Colored charts and illustrations deliver connections better than tables and figures and as users spend time looking back and forth the full infographic, they stay on the site longer. Plus, readers who like what they see are more likely to share visual guides more than articles.

Award-winning education technology Cameron Hummels Cosmological Evolution A simulation following the evolution of a large representative volume of the Universe from just after the Big Bang to the present day. We're looking at the projected gas density from the side of the cube, and our view follows the reference frame of the expanding Universe over this time. As you can see, initially the Universe starts out dense and uniform, but over time slight overdensities in the gas are amplified by the attractive effects of gravity to form the walls, filaments, and clusters seen here. Also note the axes scales change over time as the Universe expands by a factor of 100 between z=100 and z=0, and observe the significant drop in the general column density over that period.
Social Media Management Tools Showdown: Hootsuite vs. Buffer A robust social media presence can do wonders for your business, but keeping up with Facebook, Twitter, and Instagram alone can be a chore. Social media management tools help you manage all of your profiles and pages in one place, so you can focus instead on the product or service you're promoting on those channels. Here, we'll compare two of the most popular social media management apps, Buffer and Hootsuite, noting where each one excels and which one might be right for you.
3 Data visualisation Introduction “The simple graph has brought more information to the data analyst’s mind than any other device.” — John Tukey This chapter will teach you how to visualise your data using ggplot2. R has several systems for making graphs, but ggplot2 is one of the most elegant and most versatile. ggplot2 implements the grammar of graphics, a coherent system for describing and building graphs. With ggplot2, you can do more faster by learning one system and applying it in many places. 30 Tools to Create Your Own Infographics Infographics are one of the best ways to present data without making your audience yawn with boredom. There are a lot of people who have impressive data, but what they don’t know is how to create informative and well-designed infographics.

Download 91,000 Historic Maps from the Massive David Rumsey Map Collection Three years ago, we highlighted one of the most comprehensive map collections in existence, the David Rumsey Map Collection, then newly moved to Stanford University. The Rumsey Collection, we wrote then, “contains a seemingly inexhaustible supply of cartographic images”—justifiable hyperbole, considering the amount of time it would take any one person to absorb the over 150,000 physical artifacts Rumsey has amassed in one place. By 2016, Rumsey had made almost half the collection—over 67,000 images—freely available in a digital archive that has been growing since 1996. Each entry features high-resolution scans for specialists (you can download them for free) and more manageable image sizes for enthusiasts; a wealth of data about provenance and historical context; and digital, user-friendly tools that use crowd-sourcing to measure the accuracy of antiquated maps against GPS renderings. To make this document even more compelling, it contains its own bibliography.
Workshop Findings by workshop conveners: Kim Kastens, Tim Shipley, and Martin Storksdieck (last updated 1 May 2018) Introduction Visualizations can be a powerful tool for both thinking and communicating. This website is the product of a workshop designed to gather, organize, and disseminate good ideas for how educators can help learners extract insights from visualizations and express their own ideas via visualizations, and can assess learners' progress towards visualization mastery.
