De-Extinction

36 Comments

I read with interest last week the news story of a company that wants to resurrect the wooly mammoth, perhaps in ND. A fairly intact wooly mammoth tusk with all sorts of usable DNA was found in a coal mine here in the state. The company wants to use it to recreate the mammoth.

What is quite surprising to me is that the ND government is paying this company $3,000,000 to consider locating the company to ND. This a pretty fiscally conservative state, and the public reaction to the Department of Commerce spending money on this venture hasn’t been exactly supportive.

The local climate is more conducive to mammoth well-being than Texas, where the company is located. I wonder what you do with a wooly mammoth once you have de-extincted it? Let it wander around the Badlands here? Can it be fenced in at all? Raise it for meat? Have mammoth rodeos? The company thinks they can have a viable mammoth by 2028. I am glad that I will be living in Minnesota by then. I would hate waking up to find a mammoth in my yard eating the tomatoes.

What would you do with a woolly mammoth ? What would you like to see de-extincted?

Scientific Method II: Weeds And Pests

34 Comments

Our gardening goal this past week was to weed the veggie gardens and flower beds. After today’s carpal tunnel surgery, Husband will be somewhat out of commission for outdoor work.

Many people we know use the good old hoe to weed. That system has never really worked for us, as the weeds grow back so fast, so we are down on the ground puller-uppers and digger-outers. It is more labor intensive, but works much better. We also put down wet newspapers between the veggie rows and cover them with top soil. That method keeps weeds down all summer, and the newspaper disintegrates and can be tilled into the soil and improves the soil texture. It is a lot of work, though.

We don’t use herbicides at all, and only spray a fungicide called Daconil on tomatoes, roses, peas, peonies, and monarda to prevent powdery mildew and black spot. We use bacillus thuringiensis, an organic pesticide for cabbage worms. When the flea beetles attack the brassica veggies I will use Sevin, but most other insects are free to live in the garden unharmed. Bunnies just are kept out with fences. Our next door neighbor has threatened to get his shotgun and dispatch the rabbits in his yard. I would never go that far. We have never had problems with moles or voles.

Flea beetles are horrible, with hundreds of the tiny creatures showing up overnight devouring every thing in the cabbage family they can find. The flea beetles are often used as an organic solution to an invasive plant around here called leafy spurge. It is poisonous to cattle. People somehow catch a bunch of flea beetles and take them out to patches of spurge, and the flea beetles, who have a great love of spurge, eat it up. I think that is really cool! I just wish they would stay in the pastures and not come to town.

Would you consider yourself a scientific gardener? What are your preferred methods for weed and pest control? What are the worst insects, pests, and weeds you have encountered?

Flour Power

24 Comments

About two years ago, I found a great deal on King Arthur artisan flour. It is called Sir Galahad flour. I got it from a wholesale restaurant supply company. We got 50 lbs for $18.00. I thought I was buying King Arthur artisan bread flour, which has ascorbic acid as well as a little white whole wheat flour in the mix. I was mistaken, as it was a general flour with ascorbic acid but no white whole wheat. No matter. It turned out to be a great all round flour for bread and pastries. We have maybe 8 lbs left. We also have every kind of rye flour, graham flour, and other esoteric flours you can imagine. That is Husband’s doing.

We bake a lot, and it worked really well for a long time in all our breads along with Swany White flour from the mill in Freeport, MN. I think we got 40 lbs of that at the same time we got Sir Galahad. We have large bins to store it in next to our freezers.

As time has passed my French bread has become inexplicably denser and less springy. The loaves are smaller. The recipe has remained the same. I make four loaves at a time with 6 cups of King Arthur and 5 cups of Swany, adding a little gluten, and using bread salt and the same brand of fresh yeast.

We ran out of Swany earlier this month, and I ordered 20 lbs from Freeport. I love the Swany White mill. Gary, the owner, only takes cheques, but he shipped our flour so fast this month it arrived the next day after I placed the order by Speedee Delivery before I could get the cheque in the mail. The last time I ordered I gave all the information to his wife, who said Gary was down with a bad flare up of gout. I love the trust and community feel of this.

I baked French bread this weekend using the old Sir Galahad and the new Swany, and the loaves were big and puffy and wonderful. All the other ingredients were the same. In the past I have ignored comments from Master bakers who say that flour ages poorly, and you should only bake with flour that is less than 6 months old. Well, I believe them now. I plan to pep up the remaining Sir Galahad with 5 lbs of a new bag of King Arthur regular bread flour and pound of white whole wheat. Who knew? I am grateful for the Scientific Method! We will only order flour in 20 lbs bags now.

How old is your flour? What are your favorite kinds of flour? When have you used the Scientific Method lately?

Da Vinci Glow

36 Comments

Ever heard of a Da Vinci Glow?  I hadn’t… even with my dad’s interest is all thing astronomical!

It’s a real thing… It’s happens around sunset when a crescent moon is on the horizon, but the outline of a full moon is visible.  It’s called a DaVinci Glow because… wait for it… Leonardo was the one to hypothesize why it occurs.

The glow is caused by light reflecting off the Earth onto the moon.  Sounds weird, right.  Earthshine is light emitted by the Earth after the sun has gone down.  Because Earthshine is actually brighter than moonlight, the reflection “fills in” the crescent.

Although Da Vinci Glow is not rare, there are a few requirements.  It’s easier to see when there is a waxing or waning crescent during clear skies.  The fly in the ointment is that enough of the Earth needs to have cloud-cover to get the best view.  Apparently Earthshine is reflected more by the clouds of our planet than by the land or water. 

Since we have a waxing moon starting later this week, we’ll have the best chance of seeing the Da Vinci Glow this month!

Have you ever noticed this phenomenon?  Anything else in the night sky interest you these days?

Project Hail Mary

17 Comments

I don’t to think of myself as any author’s shill but…..

Spent pretty much all of three days doing not much besides reading Project Hail Mary by Andy Weir.  I’d say I couldn’t put it down but was listening to it on CD so not physically holding it.  I don’t want to give much of a recap because there are about a million spoiler alerts but suffice it to say, here is a list of why you might like it if:

  • You liked The Martian
  • You like science fiction
  • You like stories about space
  • You like science explained in a way you can understand it
  • You like humor mixed in with your science
  • You like a main character who is flawed but still very likeable
  • You like books that draw direct comparisons to current issues without bludgeoning you with them
  • You like stories that draw out a little of your emotion

I sent an email to Andy Weir telling him how much I liked it (and he emailed me back within a couple of hours!).  If there were an Andy Weir Fan Club, I suppose I would now officially be a member.  With today’s social media, are there even fan clubs anymore?

What’s the last book you couldn’t put down?

Parental Psychology

43 Comments

I never took any Psychology classes during any of my college years.  I have nothing against Psychology (and have benefited from it greatly during my life) but I just wanted to get my science requirements out of the way and Psych wasn’t offered when I needed a science class.  Most of my psychology education comes from various Scientific American articles I’ve read over the years.

I think it’s safe to say that as a parent, one REALLY needs psychology.  You just can’t make it through parenthood without figuring out your kids AND figuring out how to get your kids motivated to do what they need to get done.   YA is almost 28 and I still struggle with this occasionally.

One of the things I have figured out is that sometimes you have to come at her sideways.  She is too cool to get enthusiastic over some of my projects; when I brought home the haunted house kit (see photo above), she turned up her nose at it a bit.  If she had been with me when I purchased it, she would have indicated it was not a good idea.  But a few days ago I said “I’m going to do the haunted house tonight if you want to help”.  She responded with a non-committal grunt but when I got everything set up on the dining room table, she showed up.  And she did most of the decorating herself.   This works pretty much all of the time… Easter egg dying, jigsaw puzzles, yardwork, cookie decorating.  It even worked once on a snorkel sail when she was crabby and I said “Fine, you don’t have to go… I’ll see you later.”

If you take this route though, you have to be prepared to do the project by yourself; I think you really have to believe this or they hear it in your voice and then you’re sunk!

How to you talk your loved ones into things?

On Sunday, I texted a friend to see if I could drop off a book for her.  I knew she’d be there but figured I should give her a heads’ up anyway.  She returned my text and asked if I would mind helping her with a quick project when I stopped by.  I said “sure” because any time she does ask me for assistance, it’s not usually much assistance.  And, of course, my schedule is now “fluid”….

The project was changing the lightbulb in an outdoor light fixture.  Sounds easy enough but the light fixture is above the side door, which is itself at the top of four stairs.  We needed the tall ladder for this.  Opened up the ladder didn’t fit on the top step.  It didn’t fit over the steps either.  Leaning the ladder up right under the light fixture didn’t seem like a good idea since its full weight would be on the glass of the side door; we ended up shifting half of the weight to the left door lintel (is that the right word?). 

My friend was nervous about this procedure and although I volunteered (it wasn’t quite high enough up to trigger my fear of heights) she insisted.  Unfortunately it did frighten her and her hands shook enough that she dropped the screw a couple of times.  After the second drop we decided we’d better test the light before trying again.  She came down the ladder and I swiveled it out of the way so she could go inside to flip the light switch.  It was then that I got a very hard and painful thump on the head – she had left the screwdriver on the top of the ladder and it tumbled right off onto me. 

It broke the skin and my friend was really worried that I’d been stabbed with the business end of screwdriver (it was a Phillips).  We applied a paper towel and a small ice pack.   I was sure I’d been thumped by the handle.  There wasn’t all that much blood and a good stab would have bled more.  The physics were also on my side.  It was about a 4 foot drop from the top of the ladder to my head and the weight of the handle was enough that, like a cat, it would have righted itself and hit me handle first.

After a few minutes we finished up the job.  Fourth time was a charm; I tried again to take over the ladder climbing but after I’d been injured helping with her project, she was adamant that I stay off the ladder. 

No headache, no pain, no other symptoms.  I do have a scab now that I’m trying to avoid with the comb and the shampooing but my brush with the screwdriver doesn’t seem to have damaged me permanently. 

What hand tool would make the best weapon if you needed to protect yourself?

I see in the news that they are building what will be the world’s longest immersed tunnel.  Linking Germany and Denmark under the waters of the Baltic, construction actually began in 2020 and is expected to be complete by 2029

I’m sure lots of folks are excited about this but not me.  I don’t even like driving through the I94 tunnel downtown and last month when folks got stuck in The Chunnel for several hours, I almost had a panic attack just reading the news story about it. 

Any phobias you’ll admit to?

Soak It In

70 Comments

I am a Neil deGrasse Tyson buff.  I’ve read several of his books, follow his current podcast (Star Talk) and own a t-shirt with a NdGT quote and a bracelet that I saw on his website of the planets in order.  (I actually made my own bracelet based on his design and I added Pluto – he may be smart, but Pluto will always be one of my planets!)

One of the things that I admire most is his ability to take difficult concepts and to distill them down so that most of us can understand them.  I was re-listening to his description of how the tides actually work/exist and wondered what it would be like to take a class from him (an entry-level class of course – I’ve encountered some of his work that is NOT distilled down and it is way over my head).

My favorite classes in college were always lectures.  I don’t need any small discussion groups or multi-student projects – just let me sit in the presence of great professors while I soak up their knowledge.  Between Carleton and Metro State I took five Shakespeare courses from two different professors – fabulous.  There was a spellbinding Chinese Middle Kingdom class and the professor who taught my King Arthur in English and American Literature (yes, a real class for which I got credit) held my attention like no other.

But based on YA’s master’s program experience, the current trend in education is all about self-teaching, small group projects and collaboration (I detest this word).  Her description of every single class she took for her MBA made my skin crawl, so I guess I probably won’t be going back to school in my retirement.  I’ll have to remain self-taught in the areas that appeal to me.  I’m still doing my online Italian class; I’m almost at 900 days straight.  I’m still working my way through biographies of the English monarchs as well as the American presidents.  Banned books are high on my list of interests as well as reading on Black Lives Matter.  Science is also a love of mine although I would say I have a broad science curiosity  as opposed to a deep curiosity. 

If I were to take any classes, my first choice would be anything taught by Tyson; it’s possible he could do wonders from my understanding of physics.  Add a course covering the history plays of Shakespeare.  I’d like an economics class that specializes in the real world and does not discuss guns or butter.  Literature courses of just about any kind.  No math (I got through trigonometry by the skin of my teeth) and no classes where anything has to be cut up!  

What were your favorite and least favorite classes in school?

Henry?

33 Comments

I like to read the historical events that happened on particular days, and one of today’s I found very silly indeed.

On this day in 1889, the Second International Electrical Congress adopted the joule as a unit of energy, after James Joule, the watt as a unit of power, after James Watt, and the quadrant as a unit of electrical inductance. Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor.  What I found so silly is that the name “quadrant” was later changed to henry. The henry (symbolized H) is the Standard International unit of inductance . One henry is the equivalent of one kilogram meter squared per second squared per ampere squared (kg m 2 s -2 A -2 ).

Henry? Why not Flora or Sylvester? This got me started renaming things. “Yep, husband drove 90 Biancas to Bismarck last night. ” Or “I lost 10 Elliots with my new diet.”

Come up with some silly names for units of measurement.
