Resist Tubule (Mechanisms of Gravity Resistance in Plants From Signal Transformation and Transduction to Response): Today Flight Engineer (FE)-6 Nyberg attached a Plant Experiment Unit (PEU) with plant samples and the Dehumidifier inside the Cell Biology Experiment Unit (CBEF) and then activated the PEU program. After 32 days of growth in the PEU an ISS …
Subtleties of Color (Part 6.5 of 6)
Drew Skau and I have received a few comments on Subtleties of Color that deserve to be included. (By the way, don’t be shy. You can leave a comment here or at visual.ly) Naomi B. Robbins demonstrated that the standard land cover classification palette fails for color-deficient viewers. She also pointed out that “color-deficient” is […]
September Puzzler
Each month, Earth Observatory offers up a puzzling satellite image here on Earth Matters. The September 2013 puzzler is above. Your challenge is to use the comments section to tell us what part of the world we are looking at, when the image was acquired, and why the scene is interesting. How to answer. Your […]

Meteor Fragment Streaks Over Alabama and Georgia
Monday, Sept 9 at 8:18 PM Central Time, a baseball size fragment of a comet entered Earth’s atmosphere above Alabama, moving southwest at a speed of 76,000 miles per hour. At such speeds, fragile cometary material will not last long. Just 3 seconds after hitting the atmosphere, the meteor disintegrated 25 miles above the town …
References & Resources for Visualization Professionals (Subtleties of Color, Part 6 of 6)
The previous posts are my personal take on using color in visualization. I hope my perspective is useful, but it’s primarily a synthesis of the work of others. Here’s a list of the sources that inspired and informed this series. If you don’t have the time or the inclination to sort through the whole set, […]
