This is one of my favorites!!! It's also often mistaken for fossils because it can form these dendritic patterns in rock. It's beautiful!!
Photo of rock with dendritic pyrolusite. It's a white-ish rock and the pyrolusite looks like a bunch of little ferns across the rock.

This sculpture is described as “dendritic” which is a new word I will probably never say again. I love this surreal work of art.

Copper crystals can form beautiful leafy patterns called dendrites from the Greek word dendron meaning tree. Dendrites grow due to mineral-rich fluids moving through cracks or during rapid cooling from a melt or vapor. Vote and more👇🏼

Dendritic copper. It looks like a gnarly but sturdy old tree. Next to it are a few pennies and a label saying "Copper Michigan M5610"

Researchers envision their vaccine being used as both a treatment and a preventive, and as an approach to treating multiple cancer types.

HIGHLIGHTS • Lipid NPs carrying STING and TLR4 agonists promote synergistic type I interferons • NPs drain efficiently to lymph nodes and increase polyfunctional T and B cells • NPs improve tumor-free outcomes with memory against multiple aggressive tumor models SUMMARY We report on the utility of a "super-adjuvant" nanoparticle (NP) system as a modular, customizable platform for next-generation cancer vaccination. Using nanomaterials engineering technology, we aim to harness not only the effective adjuvanticity of whole-pathogen vaccines, but also the safety of subunit vaccines. Our lipid-based NP platform co-encapsulates agonists of the stimulator of interferon genes (STING) and Toll-like receptor 4 (TLR4) pathways to promote synergistic production of type I interferons and other proinflammatory cytokines in innate antigen-presenting dendritic cells and macrophages. Compared to empty NPs and free agonists, dual-adjuvant NPs administered with antigenic peptides or tumor cell lysate promote increased antigen processing and presentation, drain efficiently to nearby lymph nodes, increase polyfunctional tumor-specific T and B cells, and improve tumor-free outcomes upon vaccination and subsequent challenge with multiple aggressive tumor cells. Graphical Abstract The vaccine combines two immune-stimulating molecules (adjuvants) in a tiny lipid nanoparticle that enhances both innate and adaptive immune responses. The innate immune system acts as the body’s first line of defense, responding quickly and non-specifically to invaders using cells that release inflammatory signals. The adaptive immune system takes longer to activate but provides a targeted, long-lasting response, training T-cells and B- cells to recognize and remember specific threats. Together, they form a coordinated defense: the innate system alerts and activates the adaptive system, which then delivers precise and durable immunity.

Remember dendrites (from the Greek word dendron meaning tree)? They are tree-like minerals that form under special conditions. There is a lovely dendritic #copper sample on the upper right. Thanks Susie! More in comment 👇🏼

COVID mRNA vaccines also cause cancers to become sensitive to immune checkpoint inhibitors (ICIs). buff.ly/GEfJ5Zl

The tree is meant to suggest the dendritic branching of blood vessels, but it is withered. And the background consists of a purple haze—a reference to the reason I got to ruminating on the whole subject to begin with, the death of Jimi Hendrix. 4/5
Close detail of the skeletal angel of death with opium pipe tucked into its belt, hypodermic needles dangling from necklace and belt. Another cord hangs from its waist weighed down by a spoon. One forearm is tied with rubber tubing. Necrotic flesh bulges with pronounced veins.
