siphonophora:

Diatoms are a major group of typically unicellular algae, and are one of the most common varieties of phytoplankton. Unique to diatoms, their cells are encased in a cell wall of silica (silicon dioxide), which is responsible for their crystalline appearance. Diatoms are autotrophic, meaning they derive their nutrition from their surroundings by means of photosynthesis or chemosynthesis. This places them in the role of producers in the food chain.

Classification:
Eukaryota > Chromalveolata > Heterokontophyta > Bacillariophyceae

Biologists would have you call this thing an Armadillo-Girdled Lizard, Cordylus cataphractus, but I won’t be fooled. This is clearly a baby dragon. They also have this adorable habit of biting their own tails for no discernible reason. Which is adorable until you remember what the ouroboros is, and inevitably conclude that these things are also dark magic.

Magical dragons. It all makes sense.

Baby baby baby I WANT ONE baby.

Google for it, you can totally have one as a pet.

ngl, this is the first time a lizard has actually appealed to me as a pet because look how cute.

Plant viruses as gene delivery vehicles

The use of animal virus-like particles (VLPs) as vectors for the delivery of genes to mammalian cells has been explored for many years. Plant viruses are almost without exception “just” genetic material (DNA or RNA) surrounded by a shell composed of the capsid protein (CP) – with no membrane envelope. Plant-derived VLPs have not been used for direct gene delivery and expression. There have been no attempts to use a spherical plant viral capsid to deliver heterologous genes for expression in mammalian cells, even though there are several independent demonstrations of the internalization of plant virus by cells. In light of there being no direct demonstration of spherical plant viruses disassembling and thereby releasing their contents in animal cells, this paper asks the question: Can heterologous genes in spherical plant VLPs be made available to a mammalian cell and their protein products synthesized?
