Resilience of crops confirms that drought alone did not cause a 'collapse' in Mayan civilization.

But a botanical study shows that the connection between drought and depopulation was not simple. [link]

From Linda George: The gift shop in the Visitor Center at the Garden has a display case with fanciful creatures made from acorns and other natural materials. This link is a short movie featuring interactions between acorn fairies and actual birds. It's fun! [link]

Chalk is made of the remains of unicellular, planktonic organisms in the oceans of the world. For shelter, each individual cell builds a protective house from 'bricks' it makes itself. And what beautiful bricks they are! This short piece tells you about these creatures and their importance in storing CO2. [link]
 

And peaking of chalk, a recent article in Nature suggests that variations in Earth's orbit can affect the abundance of coccolithophores enough for them to actually cause alterations in the cycles of glaciation. [link]

Acorn weevil 'snouts' inspire strong materials that are simultaneously flexible. [link]

What's in a name? Kathy Keeler, at A Wandering Botanist, ruminates over what we should call the Poinsettia. [link]
