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.

Some thick fluffy moss, star shaped. It’s at the foot of some trees.

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 🫚

#ChemSky 🧪
Infographic on gingerbread graphic that highlights the chemical transformation that ginger undergoes when cooked, and shows the chemical structures of gingerol (before cooking) and zingerone (after cooking). Infographic on rooster doro wat that highlights the ingredients of the spice mix used, including holy basil, cardamom, fenugreek and ginger. The structures of sotolon (component of fenugreek), linalool (component of coriander seeds) and 1,8-cineole (component of cardamom seeds) are shown.

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!

Meet our #September feature Hannah Büttner in this year’s #calendar 2025! 👩🏻‍🔬 She explored fungal-bacterial symbiosis, loves both music & art, and carries science in her bag wherever she goes. 🎒🏜️ Read her interview here: lmy.de/FUIJC 🎙️

#FacesOfScience #LeibnizHKI
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. A graphic calendar page with a turquoise-blue gradient background. In large pink letters it says “SEPTEMBER,” and underneath: “Hannah Büttner.” At the lower left is the “Leibniz-HKI” logo with the text “Leibniz-HKI Calendar 2025.” At the lower right, the word “SWIPE” is written in bold black letters next to a large purple arrow pointing to the right. A young woman in a white lab coat is working in a laboratory. She is holding a pipette and placing a sample into a scientific instrument. On the right side of the image, there is a speech bubble in a turquoise color gradient with the text: “I particularly enjoyed structural elucidation and analytical challenges.” Below, the logo of LEIBNIZ-HKI is visible. A large purple arrow points to the right. A young woman with glasses, wearing a black t-shirt and green trousers, stands indoors next to a large aquarium full of fish and aquatic plants. She holds a viola under her arm and looks thoughtfully into the distance. Her reflection is visible in the aquarium glass. Colorful text bubbles on the right side of the image read: “I like it when Art and Nature come together.” The words “Art” and “Nature” are highlighted in bright, decorative fonts. At the bottom left corner, the logo “LEIBNIZ HKI” is visible.

A wildlife photographer joked that his wife managed to capture an extraordinary photo that outdid him: a European eagle owl, one of the world's largest, perched on his camera lens.

I figured I'd share what this incredible bolete's pores look like since it's one of my favorite things about this beautiful mushroom. Red-pored bolete is an apt name for this, isn't it? Maybe they're more of a dark pink, but regardless, that color is mesmerizing, in my opinion! 🍄📷 📸🎞 🌿🌱 🟢 🍄 📷 🍄‍🟫
Soft green is seen around the edges of this photo, while the rest of the entire image is filled with the underside of a Red-pored bolete, which has, as you might imagine, very red (or dark pink) pores. Its bulbous pink stipe obscures some of our view at the bottom middle of the shot with a blurry round shape. The margin of the cap is also visible with a light pink color and very tiny water droplets visible in some spots. The red pores look almost soft and fluffy, with tiny divots creating small dark spots throughout.
