I love this zoomable interactive display of British & Exotic Mineralogy. To create it, Nicholas Rougeux collected 718 hand-drawn mineral illustrations by James Sowerby sourced from a pair of multi-volume books called British Mineralogy and Exotic Mineralogy, published between 1802 and 1817. Then he arranged them according to hue and brightness in a collage worthy of Knoll.

The John Muir Laws blog features lots of educational resources about nature journaling and sketching in a variety of mediums, intermixed with conservation information. Also offers resources for educators.
Some of the good stuff (a sample, there’s too much to link, the whole blog archive is a treasure trove)

Archaeologists found the bones of three young African men in a 500-year-old mass grave in what is now Mexico City. The chemical makeup of their bones sheds light on their earlier lives in Africa, and forensic analysis reveals hard, painful lives and young deaths.
How the dead speak
Archaeologists unearthed the mass grave in 1992 while digging a new subway line in Mexico City. Five hundred years earlier, the site had been the grounds of the Hospital Real de San José de los Naturales. The Spanish colonizers had built the hospital to treat indigenous people—that’s what “los Naturales” means in Spanish—but these three men were African, not North or Central American. Their bones radiocarbon-dated to the 1500s CE, which makes them part of an important but often anonymous group of people: the first African people abducted in their homelands and brought across the Atlantic Ocean to European colonies in the Americas.

The largest insect migration in the world ends each year in Michoacán, Mexico. Millions of monarch butterflies travel from the United States and Canada to pass the cold months in the towering trees of this beautiful forest. On their incredible journey, the butterflies travel around 2,800 miles.

Get ready to count some birds, because Audubon’s Great Backyard Bird Count starts this Friday, February 14, and runs through Monday the 17th. This is a beginner-friendly event, even easier to join than the Christmas bird count.
You don’t even need a backyard. Just find a place where you’re likely to see some birds. This is a great time to visit a local park or wildlife refuge. To participate, count birds for at least 15 minutes “in as many places and on as many days as you like.” You’ll keep a separate checklist for each outing. In addition to noting the types of birds you see, make sure to count (or estimate) how many individuals you saw. Two cardinals at your feeder. 20 geese on the lake.
