Screenshot of a CNN segment shared by Acyn. A split-screen shows commentator Lydia Moynihan on the left and Kevin O’Leary on the right during a heated exchange. The chyron reads, β€œObama: Dems need to avoid scolding and β€˜virtue-signaling.’” The post quotes O’Leary referencing China and concentration camps, and McGowan responding about West Virginia.

I spent my childhood inside of American concentration camps. I know one when I see one. And that is what ICE is building.

Japanese artist Yayoi Kusama has said that her pumpkins act as self-portraits. The idea began as her parents owned a plant nursery and she has described the pumpkin as β€œa spiritual home,” a form in which she sees herself reflected #Womensart

Found an additional graphic that gets even more of these quotes together.

I've kept "I hate myself, I hate clover, and I hate bees" pinned above my desk since I first started studying evolutionary biology as an undergraduate. So relatable to get extremely frustrated with your study system.

Mamdani: "I speak of Renee Good, whose final words to the man who murdered her were, 'I'm not mad at you.' I speak of Alex Pretti who died as he lived, caring for the stranger. ICE shot him bc he did something they could never fathom ... let us offer a new path: one of defiance through compassion."

Yesterday was the midway point between the winter solstice & the vernal equinox & today is Imbolc, the pagan celebration of the return of the light. We’re climbing out of winter & the whole botanical calendar (save snowdrops & aconites) is ahead. A very good thought in case you need it today 🌿:

My linocut with portrait of Kathleen Lonsdale in gradient of lavender at the bottom to indigo at the top. She looks like a serious woman with a big mop of curly hair, round glasses, in a floral shirt and blazer. To her left is her own first drawing of electron density projection calculated for hexachlorobenzene. In front of her in black is her own one crystal model of hexamethylbenzene (with spheres for atoms and bars to indicate bonds or for structure and a small tag).

NEW: Expensive gas still biggest driver of high UK electricity bills, says UKERC

"Volatile, gas-linked market prices – not green policies, as some misleading claims have suggested – dominate the real-terms increase in bills since 2021."

Confocal laser scanning microscopy (CLSM) images of Aegilops cylindrica leaves infected with IPO323 (incompatible) and Zt469 (compatible) Zymoseptoria tritici isolates. Microscopic images from CLSM analysis using maximum projections of image z-stacks. Cell nuclei and plant tissue are visible in purple, and fungal hyphae are in green. Except for the 4 days postinfection (dpi) sample of the incompatible interaction, only fungal hyphae growing within the plant tissue are shown. Letters indicate which infection stage is represented by the images. Time points listed in purple were chosen for RNA sequencing analysis

Rune Hansen et al. reported that the substomatal cavity is a crucial check point where the devastating Septoria blotch (Zymoseptoria tritici) infection is stopped. Understanding this mechanism is key to future wheat immunity. Learn more: https://doi.org/10.1094/MPMI-11-24-0147-R
