Master! Planet of Doom is now available on the Big Finish website.

The Master and Vienna Salvatori form an unlikely alliance when they’re forced into joining an expedition to a forbidden planet. Accompanied by elite marines, government scientists and a corporate mercenary with access to some very old UNIT files, they go in search of an ancient, subterranean labyrinth infested by an alien lifeform the Master knows all too well…

Excessive Inhibition

People with Down syndrome have three copies of chromosome 21 instead of two, meaning an extra copy of each of the 250 or so genes on the chromosome. Figuring out which are responsible for the various issues associated with Down syndrome is challenging. But scientists have recently determined that the gene encoding DSCAM – a cell adhesion molecule involved in neuronal circuitry – is a likely cause of at least some of the neurological symptoms. Studies in mice with simulated Down syndrome revealed an extra copy of DSCAM caused chandelier cells (like the one pictured) to develop more axons. Chandelier cells are inhibitory neurons and naturally have large numbers of axons – their branching shape giving the cell its name – but extra DSCAM caused even more axonal connections with target cells and thus greater inhibitory activity. Further work may reveal how this inhibition leads to neurological symptoms and whether it can be modulated.

Neurons and their importance

  neurons and their importance Neurons are specialized cells that make up the nervous system. They are responsible for transmitting and processing information through electrical and chemical signals in the brain and throughout the body. The importance of neurons lies in their role in cognitive and physical functions, such as sensory perception, motor control, memory, emotions, and behavior. They…

I THINK, THEREFORE I JUDGE.

Wisdom has to be judgmental… Or it’s not. So why is “judgmental” such a curse adjective in the US? Why is wisdom all too often cursed in what is, de facto, the leading democracy? Indeed, thinking is noble, the most defining human activity. But to think is to judge.  Thinking consists in contemplating one or multiple choices, and then deciding upon one or some of them as true, or optimal, and…

I was being chased through the woods by a monster that looked like it was made up of several rolled up bundles of cooked spaghetti and drenched in blood and when it caught me it started eating my face.

i had a very strong cup of coffee and had an "epiphany" if you could even call it that but. i never fully registered that origami is kind of entirely just 'mountain' and 'valley' folds. that's it. the most complex thing you make would still just be those 2 folds mixed together. like.

Axon Ax-off

Like trees growing in the wild, the branches or axons of our nerve cells reach out as they develop. In the optic tract of a zebrafish, some branches of these retinal ganglion cells are ‘pruned’ to guide the accurate shape of circuits behind its eyes. Like snipping at a bonsai tree (although about 1000 times smaller), cells on one side of the tract (highlighted in red) send signals that help to cut off stray axons of cells on the other side (blue), leaving grouped or 'sorted' neurons behind (seen on the right). Researchers using CRISPR/Cas9 technology block the activity of ones of the genes involved, gpc3, leaving the optic tract in a disorganised unpruned state (left and middle). Insight into this molecular tree surgery might influence therapies for the human brain, which also uses a form of gpc3 – offering a helping hand in shaping neural circuits that develop errant branches.

ART REQS???? *runs around like a toddler* uhmmm could you draw ship art of my oc, axon and morro… pretty pleaseeeee /nf

Axon ref (the first 2 drawings are from my amazing beautiful husband @fruity-legos)

RAAHHHSJEJ I really hope I portrayed them well!!!! Especially Axon!!

I love axons design btw!

If you haven't fallen asleep yet,

How about: Storm's?

(also hope your able to get some sleep soon mina if your still up doing the three sentence prompts!)

Me? Asleep at 11:30? Bahahaha. (In all seriousness I might go to sleep early but not this early!)

It doesn't take long for Shadow to realize what woke him up from his dreams, curled up against Vio's side. He raises his head and rubs at an eye, waking up more than he wants to at the loud rumbling just outside. Drops of what he now knows is rain pound away at the house's roof and window, but he doesn't think the growling is rain.

"Um," he whispers, glancing over at Vio in the darkness. He hates to wake him up, since he fought a lot to get Vio to sleep in the first place, but if there's something wrong... Shadow reaches over and wraps a hand around Vio's arm. "Vi? What's that? Is it okay?"

Vio's eyelids flicker, and he shifts. "What's what?" he slurs.

Shadow waits another moment—light flashes outside, and then another loud sound passes above, close enough to make the windows rattle. He presses his lips together and holds onto Vio a little more tightly, his mind running away with all kinds of awful scenarios.

"Mm... That's just thunder," Vio says, rolling over. He lets Shadow keep ahold of him and mumbles the explanation. "Static in the clouds builds up until it shocks the ground, and the air moving really fast makes the sound. Called thunder."

Shadow takes a second to comprehend that. "So it isn't anything bad?"

"Mm-mm. Just a storm. I can show you a book about meteorology—" Vio sounds more awake now.

"No, no. If it's just a storm, it's just a storm. I believe you. Go back to sleep." Shadow lays back down, still a bit tense.

Lightning lights up the room again, close, and Shadow winces. The thunder is loud.

Vio wraps an arm loosely over him and closes his eyes. "Nothing to be afraid of."

"Okay." He'll try. In the meantime, the rain is nice, and so is laying here. Shadow hikes up a blanket over their shoulders again and focuses on Vio's evening breaths.
