Bats and outbreaks

For Reuters, Julia Janicki and Simon Scarr, with illustrations by Catherine Tai, show why bats make ideal hosts for viruses. They went with the old nature journal aesthetic, which I appreciate. One reason bats have started outbreaks is longevity, shown in the chart above, which compares mass against lifespan. Bats live a surprisingly long time...

One reason bats have started outbreaks is longevity, shown in the chart above, which compares mass against lifespan. Bats live a surprisingly long time for their size. Plus, they can fly.

Cooling Gulf Stream

This is quite a dive by Moises Velasquez-Manoff and Jeremy White for The New York Times. They look at the potential danger of melting ice from Greenland flowing into the Gulf Stream. An animated map of currents and temperature, reminiscent of NASA’s Perpetual Ocean from 2011, shows what’s going on underwater. The piece flies you through as you scroll with a familiar view as if you’re in space looking down....

Schools should open their windows for ventilation

As schools begin to reopen, The New York Times illustrates why classrooms should open a window for ventilation. Lower viral concentrations swirling around means reduced exposure. The 3-D model to show airflow was already something, but keep scrolling to see the cross-sections. Then scan the QR code on your phone to see the simulated data with augmented reality.

I struggled to decide on which blog to put this post. The reality is it bridges the graphical and analytical sides of me. But I ultimately placed it on the dataviz blog because that's where today's story starts. Data visualization has few set-in-stone rules. If pressed for one, I'd likely cite the "start-at-zero" rule, which has featured regularly on Junk Charts (here, here, and here, for example). This rule only...

Definition of an algorithm

Oftentimes we see “algorithms” referenced in various contexts, but the definition of an algorithm is often unclear. For MIT Technology Review, Kristian Lum describes what an “algorithm” means these days: In statistics and machine learning, we usually think of the algorithm as the set of instructions a computer executes to learn from data. In these fields, the resulting structured information is typically called a model. The information the computer learns...
