My 14 yr old grandson comes to me on Mondays for Nature Studies & this term we're doing Natural Selection. Today we learned about the fascinating example of the Peppered Moth, and here's Indy's write up at the end of the day! I love learning alongside him... 😀

Close up photo of 4 mature slime mold sporangia. Each bright red sporangium consists of a short, thin stalk attached to a small cup from which a tubular, cotton candy-like spore mass protrudes. They are attached to dark coloured dead wood. The fuzzy photo background is mainly light green.

When the world serves up a shit tsunami - basically, everyday - I find spending time watching the hummingbirds keeps me calm. Took about two weeks of daily work to get this one comfortable enough to hand feed. It's a process.

Prosopanache is the tropical American answer to Hydnora of Africa. The two genera are sisters, holoparasitic & lack chlorophyll. They appear above ground only as flowers. This is Prosopanche americana, parasitic on legumes. 📷: Agustín Zarco CCBY4 #Aristolochiaceae #Botany 🌾🧪🌱

Day 9's #ChemAdvent entries are linked by ginger - a key component of gingerbread and also one of the spices found in rooster doro wat, an Ethiopian spicy chicken stew eaten after periods of fasting, including at Christmas 🫚

Apparently today is National Harvest Mouse day so here are some rather adorable photos I was able to take a couple of years ago, on the best photography day ever.
Harvest mice are astonishingly cute, and fast, and some of the other creatures I photographed that day would have loved to eat them!

A young woman with glasses sits on a wooden bench outdoors, smiling at the camera while holding a viola on her lap. She is wearing a black top, wide green pants, and black heeled sandals. On the left side of the image, there is a large colorful speech bubble with the following quote: “I primarily focused on the symbiosis between fungi and endosymbiotic bacteria. We identified natural products produced by the bacteria that protect the fungi from predators and play a key role in the symbiotic relationship.” At the bottom left, the “Leibniz-HKI” logo is visible. At the bottom right, a large purple arrow points to the right.
