Cocktail Inspired by Frank Herbert’s Dune

I posted a video with some thoughts on Dune and Nootropics. I also came up with a cocktail inspired by the book. I am in love with this cocktail. The 2021 film is coming out soon on HBO(!) so if you want to make this for your screening, here’s the recipe:

Spiced Tequila Sour Of Shai Hulud (May His Passing Cleanse the World):

Assemble in a shaker with ice:

1.5 oz Corzo Silver Tequila (for the memory of the desert sands of Dune)
0.75 oz ginger syrup* (to stimulate the mind)
0.75 oz fresh lemon juice (it gives its body’s water that the tribe may survive)
Two dashes cinnamon bitters (for the Spice must flow)

Shake

Place a large, clear ice cube in a glass. Add one bar spoon of blue curacao (for the blue within blue eyes of the fremen). Strain the drink over the cube and serve.

*To make ginger syrup: Assemble 0.5 cup sugar, 0.5 cup water and ~4 ounces of sliced fresh ginger in a pot, heat over medium heat while stirring until the sugar dissolves and the mixture just starts to bubble. Strain into a bottle for storage.

Hydra Video! Links and comic, too

I just posted a Video about Hydra and Humanized Organisms. A long, strange train of thought resulted in this comic, too. Art credit goes to Snowman – I love it.

I got to thinking about humanized organisms while I was reading about hydra. Hydra make good models to study the biology of aging because they seem to be immortal: they don’t seem to age at all. If we knew how they accomplished it, it might help us understand how to slow aging. How do we know that they don’t age?

Prof. Daniel Martinez observed groups of hydra for years. He carefully fed them and kept them in separate tubes. Each one was observed making buds – little baby hydra – but the old hydra was put into a fresh tube alone every time. The researchers waited for any of them to get old and die… and none did. Well, maybe they didn’t wait long enough? We can only compare them to other creatures in the same weight class.

Longevity tracks body size and time to first offspring. So orcas (weight 1 million grams, first offspring at 25 years) live far longer than voles (weight 10 grams, first offspring within a few weeks of birth). Hydra weigh in at a fraction of a gram and have their first offspring a few days after being born. But they are still alive and reproducing for years, thousands of times longer than the trend would predict.

What allows hydra to accomplish this? How do they regenerate? What’s special about their stem cells that they don’t deplete? Can we study hydra in a way that’s relevant to human longevity?

Modernity and youtube production values

We sometimes think (in our age of progress) that if we look back, we must see very primitive creatures. 

But even if we go back ten thousand years, we don’t find primitive humans. We find modern humans.  Genetically, we have not changed very much in 10,000 years. What has changed? We have learned a huge amount of chemistry, biology, etc. Of course we didn’t know which bits were useful. It took a hundred years to figure out. That’s how science works. 

The discoveries of past centuries created some rapid changes. Example of progress: within a few hundred years we went from knowing what gunpowder was, to seizing guano Islands, to synthesizing ammonium nitrate to nuclear weapons. 

Ancient impulses with modern weapons are weird. I have this picture in my head of an angry person saying “I’m going to get that guy. I’m going to go lay claim to a guano Island, refine potassium nitrate, make black powder, and use an explosion to propel a small metal ball through his body.” Then the pre-modern human says “I’d just hit him with this rock. Simpler.”

Anyway.

A silly pun about lichen

The strange taste of memories; lichen comics; Week 13 of 2021

Funny stuff:

A strange thing happened. I ate a Walmart fudge brownie, then some peanuts and drank some coffee. It tasted exactly like a memory of waiting for a table at Smitty’s with my grandparents. The yellow wavy glass, the vinyl bench, the smell of my grandmother’s perfume, the sound of silverware, the juice glasses with the distinctive bulgy profile… it all came back. It was clear in my mind to a crazy degree. It only worked once, though. No matter how many brownies I ate.

Unrelated: I’ve been doing some macro photography. I saw this weird moss and lichen on the top of a post. The vibrant red color is very interesting. I would love to know what the pigment is. The red nodules were about 2 mm in diameter. What a fun lens. It made me think of an old comic, A Softer World. So, I tried to make some things inspired by their style.

Week 8 2021: Pilgrimage to the Temple of Power

My wife and I took a drive up to the Temple of Power. It was pretty cool, and pretty much deserted. It’s a sculpture made from salvaged electrical equipment at the Gorge powerhouse. We saw an eagle fly over us while we were wandering around. It was pretty cold, but very pretty. In retrospect, I wish I’d captured video so I could do a vlog.

I saw that Netflix is Adapting the ‘Redwall’ Books Into Movies, TV Series. I liked those books as a kid. They got repetitive after a while, but I still remember parts of Mossflower very fondly. I read them at a point in my life when I didn’t want to like anything the other kids liked (I was a hipster before it was cool, bruh), but Redwall won me over. Wholesome good fun. I hope the new series takes the material seriously.
