Geeking Science: Self-burying seeds

Image from the Carnegie Mellon University

Humans have been sowing seeds for generations; sometimes digging holes with fingers, dropping the seeds in, and burying them in the dirt, and other times following the more traditional method of plants themselves – scattering them in the wind and hoping for the best. One is labor intensive and the other is just a play against statistics, praying to the capacious weather gods that the birds and weather will be on our side.

But what happens when you absolutely must plant things in hard to reach areas, for example, reforesting an area after a fire? Today’s drones answer half the equation with accessibility – flying easily to places that could take hours and remarkable physical danger – but that doesn’t get the seeds planted.

Wouldn’t it be nice if seeds could plant themselves?

Scientists recently stole an idea from seeds and upgraded it. Erodium have a stalk that taps into different moisture reactions to create a screw action for burying its seeds. It works okay – the plant exists in nature after all, but the natural best results depends on uneven soil with crevices because up-and-down for the one tail seed changes with each flip until the bury is successful. Once buried, the one-way directional hairs keeps the seed from popping back out and the stalk continues to wind and bury the seed deeper.

To upgrade the design, engineers at Carnegie Mellon University found that three coiled tails create nearly a 80% success rate. In a world with birds, rain washes, and rocky soil, this is amazing.

The device is made from biodegradable wood. And the carrier area can hold pine and other tree seeds, or crop seed. Plus it can been used to deploy and bury “nematodes (worms used as natural pesticides), fertilizers, and fungi.” (Spice) Other real-world applications outside of farming is reducing landslides by increasing deep-root vegetation and using the corkscrews “to implant sensors for environmental monitoring.” (Spice)

The inventors are still working on how to create and deliver these carriers at scale needed for farming crops and reforestation, but the device itself works great.

Two important questions for any invention – 1) can it be done and 2) how do we make enough for the invention to be useful. We have the “yes” for the first, now we need to Geek the Science on the second.

Writing Exercise: Create a Collage

A picture is worth a thousand words, but can it create a story?

Collages come in a variety of shapes, sizes, and colors. They can be cut from books or photos or drawing. Cloth, sparkles, and pressed plants. Scrapbooking is one of the many presentation methods.

For both the reading and writing exercises, the challenge will be to make a collage. You can do it on a computer or just paper, glue, and anything else handy.

READING EXERCISE: Create a collage about your most recent book. Comment below what you aimed to share – the emotion of the book, the characters, the landscape, or something else entirely.

WRITING EXERCISE OPTIONS:

  1. Create a collage, then write a flash or scene about it. Share how the collage and flash interacted below.
  2. Create a collage about your present work in-progress. Share if the collage gave you new insight to your book, or why you think it didn’t add anything.
  3. Have a scrapbooking friend (or you child) create a collage for you for which you then write a flash or scene.

Gardening: Z is for Zucchini

2024 GARDENING / HOME IMPROVEMENTS

This year I added a raised garden after tax season. On and off for a little gathering all the parts, then two days of concentrated effort, but the home for Tomatoes, Yellow Squash, and Zucchini is complete! (Just like the A-to-Z challenge.)

First thing I did was get my containers in order. I bought mint and tomatoes in early April then never had a chance to plant them. Eventually I cleared out the growth from 2022 and 2023 when I ignored the pots, but by then the mint and tomatoes were mostly dead.

I went out and bought more mint and tomatoes, plus supplies for the raised garden. Now the deadline kicks in. I need to get the new plants in a container soon.

I got the raised garden back in January when I was flush with day-job money and hope that THIS is the year I will find time during tax season to get my gardening done before the heat of May kick in for the south.

Yes, I do this dance every year, and every year I fail, but this year I was determined. (shush you, yes, the mint died – which takes some very determined neglect, but this year will be different!)

I had the raised garden pieces. Eight screw-nut combinations are needed to attach each panel together and the end result would be a two-foot deep bed. One hundred and twelve screw-nut combinations later, I got it assembled.

Working on the table with all the nuts and screws until the parts get too big.

 

 

First part assembled.
Nuts-screws are really hard to tighten all by yourself, but I got it done!!! The empty form for the raised bed is complete.

 

Now that the form is ready. I need to go get the dirt. Being just me and my mini-van (their name is Grey), I will need to buy bags of soil.

Soil is purchased – nine bags, plus 3 bags I already have for a total of 12. I hope it is enough.

 

 

Now to get the final touch, those plants that I bought last week. Did I get all of this done in time?

Everything is planted. It looks pretty. Hopefully it will taste delicious in a few month. The wonderful things about making the raised bed is it should be easier going forward to get everything done in future years. We shall see.

I got this done by the May Heat Deadline – go me! (And thanks to everyone on A-to-Z for their visits. Have a great year.)

It is not enough. The raised bed is about half-full, but that is all the energy I have. I’ll add more next year.

Gargoyles are monsters and monstrous concepts carved into stone. Artists take their inspiration for these monsters from a variety of places.

V is for Vader. But Alien and Gizmo (from Gremlins) also have found there way to the sides of cathedrals.

Geeking Science: Do You Want Fries in Space

Food is essential. No only for survival but also for socialization. If you have hung out on my website for any amount of time, you know that meals are a mainstay in my flashes and that I will Geek the Science out of food – everything from the science of Fried Chicken to how Nori develops in nature.

Time to talk about food in space. Last month I touched on soda being a non-starter in an environment where you can’t burp with any grace. Next question on the table, is space exploration going to be sans fries too? I mean, the movie The Martin, Matt Damon raised potatoes – are we going to have potatoes and no fries?!?

It was a worry for a bit – again the action of microgravity and gas which takes out beer and Coke – might mean the bubbling cauldron of oil won’t work but fries do look like they can stay on the menu after some tests run in parabolic flights. (Lea) Hamburgers – with yeasty bread and greasy meat and cheese, all of which are high gas items – may not make it, but at least we get to keep our fries.

Seems strange to test out cooking techniques for space-worthiness, but food is a necessity on earth and food will be a necessity in space. In addition, like the invention of Tang (Cordell), all knowledge adds to Earth’s present benefit as well as our decedents braving the Black.
