Upcoming CDC ACIP September Meeting on MMVR & Covid-19 Vaccines

The upcoming meeting on the MMVR and Covid-19 vaccines will include voting on the MMVR and Covid-19 vaccines. Usually, the committee posts the actual voting questions, which so far I have not seen on the meeting agenda. I’ll be looking for them in the next couple of days.

Here is the link to the Center for Infectious Disease and Policy (CIDRAP) at the University of Minnesota article which bears directly on the meeting topics.

The Bouncy Egg Caper on Easter!

Want a scientific excuse to waste an egg? Sena and I found this experiment that uses vinegar to make a bouncy egg yesterday.

We put a whole raw egg into a bowl full of vinegar and let it sit for 24 hours. Initially, a couple of hours after we put the egg in the bowl of vinegar, Sena noticed pressure building up in the bowl. Even though the lid was on, vinegar was starting to leak out so she set it inside a larger bowl.

I started to worry a little about whether enough pressure would build to blow the lid off in an explosion—but it never happened.

I think a lot of people get this idea around Easter. The main thing that happens is the vinegar (a weak acid) eats away at the egg shell (which is made of calcium carbonate) until the shell dissolves. Carbon dioxide gas bubbles form. It leaves a rubbery membrane behind. The water in the vinegar diffuses across the membrane.

The egg had a lot of bubbles all over it and was visibly larger. The shell had completely dissolved—and it bounced! Sena tried bouncing it from higher and higher levels until the inevitable splat. All that was left was the yolk and the membrane.

It kind of reminds me of the morgue autopsy scene in the 1997 Men in Black movie between the deputy medical examiner Dr. Laurel Weaver and Agent J (everything reminds of Men in Black movies):

Dr. Weaver: Feel that? Where the eggshell should be? Notice anything strange?                 

Agent J: No, all fine.       

Dr. Weaver: Doctor, the whole shell is missing.                  

Agent J: Well, of course. That’s obviously the first thing I noticed. What I was pointing out is the fact that there are no… pieces…of it left. You know, so the shell is intact; wherever it is whole, somewhere. That we can be sure of.

Connection Between Cribbage and Obituaries?

Just for fun today (which is New Year’s Day of 2025) after Sena and I played a few games of cribbage, I searched the internet using the term “cribbage in Iowa.” I found a local newspaper story entitled “There’s No Crying in Cribbage. There’s No Politics Either,” published August 18, 2024 in the digital version of the Cedar Rapids Gazette which, by the way, promised me that I have “unlimited” access to articles.

It was written by Althea Cole and it was longer than I expected it to be. Much of the story was about the longstanding history of annual cribbage tournaments at the Iowa State Fair. She also mentioned that her grandfather had been an avid cribbage player.

But I was also puzzled by the significant number of obituaries that popped up in the web links. I’ve looked up cribbage dozens of times but not with this particular search term. I checked several of the obits and found the majority mentioned that the decedents had been avid cribbage players.

I’m not sure what to make of this. What does it mean that cribbage is associated with obituaries in Iowa? I suppose some would say that it might mean that cribbage is a game mainly played by old people—which is probably true. The American Cribbage Congress (ACC) web site makes it very clear that they encourage young people to play cribbage. Be patient, the site takes a while to load.

That said, whenever I see photos of people of playing cribbage, almost all appear to be over 50 years old.

So, I tried searching the web using the term “cribbage in Wisconsin” and didn’t get any obituaries. I got the same result with “cribbage in Minnesota” and “cribbage in Illinois.” I decided not to run the search for every state in the country, because I think the point is already made. For whatever reason, cribbage in Iowa seems to be associated with obituaries and advanced age.

I imagine some reading this post might point out that the connection with obituaries in Iowa and cribbage could just mean that a lot of Iowans enjoy cribbage. That could be true. However, on the ACC web site, I can find only one city in Iowa that has an ACC Grass Roots Club, and it’s in Des Moines.

There’s a web article entitled “Is cribbage too antiquated to survive this digital world? Players and board collectors sure hope not.” It was written by Rebecca Zandbergen in April 2023 and I reviewed it again today. One thing I can say about cribbage is that it’s probably good exercise for the brain. I can find plenty of article which praise cribbage as a way to keep your brain healthy and engage socially.

I don’t know if there are any scientific studies on the benefits of cribbage for your brain. I had trouble finding them on the web, although I admit I didn’t conduct anything like a thorough search. I did find one study on the association of playing cribbage with social connectedness.

Kitheka, Bernard & Comer, Ronald. (2023). Cribbage culture and social worlds: An analysis of closeness, inclusiveness, and specialization. Journal of Leisure Research. 54. 1-21. 10.1080/00222216.2022.2148145. Accessed January 1, 2025.

“Abstract: Recreation specialization through the lenses of social worlds is a common approach used to describe how people define and are defined by recreation activities. This ethnographic study investigates the social worlds of cribbage players. The study analyzes cultural structures through the lenses of closeness, inclusiveness, and recreation specialization. Using survey questionnaires, informal interviews, and researcher observations, data were collected at cribbage events over a period of 3 years. Findings reveal a distinct cribbage culture characterized by varying levels of commitment, specialization, and degrees of connectedness. The study contributes to the currently limited literature on social worlds and indoor recreation specialization. It provides insight as to how people align at a community level to find meaning via recreational activities. Data also reveals a lack of social diversity in the cribbage community. Findings could be used in leisure programming for diversity and inclusion at community and grassroots levels.”

There was also a paper entitled “Cribbage: An Excellent Exercise in Combinatorial Reasoning:

Markel, William. (2005). Cribbage: An Excellent Exercise in Combinatorial Thinking. The Mathematics Teacher. 98. 519-524. 10.5951/MT.98.8.0519. Accessed January 1, 2025.

Abstract: Card games have long been a rich source of combinatorial exercises. Indeed, determining the probabilities of obtaining various hands in poker, and often in bridge, has been standard fare for elementary texts in both probability and combinatorics. Examples involving the game of cribbage, however, seem rare. This omission is especially surprising when one considers that cribbage hands offer excellent applications of combinatorial reasoning.

It’s a math thing, which is good for brains. Math won’t kill you and neither will cribbage. Happy New Year!

Are These Compass Flowers?

I have misidentified plenty of plants and the compass flower is one of them. We were walking the Clear Creek trail the other day and saw what I thought was a patch of compass flowers. See what you think, judging from the featured image.

Anyway, I thought the flower itself pointed in a particular direction, but it’s actually the leaves as I rediscovered after looking it up.

As a real expert points out, it’s the edges of the leaves that point North/South.

Partial Social Eclipse Viewing on the Pentacrest April 8, 2024!

The University of Iowa Dept of Physics and Astronomy and the Sciences Library invites the public to view the partial solar eclipse on April 8, 2024 between 12:30 PM-3:00 PM at the Pentacrest and the Sciences Library courtyard. Solar eclipse glasses free while they last.

The Science on Super Beets?

Sena recently got her bottle of Super Beets with Grape Seed Extract delivered the other day. They are capsules and the label enthusiastically advertises that they are “non-GMO” and will enable the average human to leap tall buildings in a single bound within just minutes of swallowing a total of 9,000 capsules (3 caps per serving and 90 servings per bottle). Just kidding. Sena will take only one capsule a day for now.

They are made and marketed by HumanN and they prominently display important information on the bottle:

“These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”

Just so you know, the FDA doesn’t approve dietary supplements for safety or effectiveness, although they recently put together a review of scientific data on Cannabis for the HHS which may lead to the DEA changing the schedule of marijuana from Schedule I to Schedule III along with the scientific conclusion that certain formulations of the product may enable the user to leap tall buildings in a single bound—or least feel like he can. Just kidding.

Wait till you see the data on their new product, Chupacabra Chewables. The chews are shaped like little chupacabras and mutilated chickens. Just kidding, they don’t make anything like that, and even if they did, you can be sure it would be non-GMO.

Even though the FDA does not approve dietary supplements (or disapprove of marijuana apparently), that non-GMO detail is something the FDA does have an opinion about. They say on their Agricultural Biotechnology web page that “GMO foods are as healthful and safe to eat as their non-GMO counterparts.”

I searched the internet for studies on super beets and grape seed extract and it turns out there has been some research published about them. There was a meta-analysis in 2017 in which the results that beet juice has blood pressure lowering effects:

Bahadoran Z, Mirmiran P, Kabir A, Azizi F, Ghasemi A. The Nitrate-Independent Blood Pressure-Lowering Effect of Beetroot Juice: A Systematic Review and Meta-Analysis. Adv Nutr. 2017 Nov 15;8(6):830-838. doi: 10.3945/an.117.016717. Erratum in: Adv Nutr. 2018 May 1;9(3):274. PMID: 29141968; PMCID: PMC5683004.

And there was a randomized, placebo-controlled study also published in 2017 (a good year for supplement studies evidently) showing that grape seed extract modulated blood pressure. It also relieved perceived stress:

Schön C, Allegrini P, Engelhart-Jentzsch K, Riva A, Petrangolini G. Grape Seed Extract Positively Modulates Blood Pressure and Perceived Stress: A Randomized, Double-Blind, Placebo-Controlled Study in Healthy Volunteers. Nutrients. 2021 Feb 17;13(2):654. doi: 10.3390/nu13020654. PMID: 33671310; PMCID: PMC7922661.

I’m going to pass for now on the beet and grape seed extract caps. I can already leap tall buildings in a single bound.

The Geezer Remarks on Superfoods

Sena is big on eating healthy, which is a good thing. On the other hand, we don’t necessarily always like the same foods. And there’s the whole issue of what people call superfoods nowadays.

Funny, when I was a kid, I used to just refer to superfoods as “yuck!” There are variant spellings.

I read the Wikipedia entry on superfoods and it essentially says there is officially no such thing.

Take beets—please!

Sena’s big on Beets and Leeks. I’m not a big fan. I’ll eat them, of course. There’s nothing wrong with them that intravenous ipecac and a stomach transplant won’t fix. The drawback is the medical bill.

I don’t think we’ve ever had kale. Does that make the superfood list? I think it’s the same thing as mustard greens, okra, and other building materials similar to shingles.

I tried okra when I was a student at Huston-Tillotson University (then Huston-Tillotson College). I was offered this slightly slimy substance as part of a dinner at the home of my Religion and Philosophy professor and his family. It’s slimy because it contains mucilage, which is (correct me if I’m wrong but I’ll naturally ignore you) also the name of the glue we used in grade school to make valentine cards.

In fact, think of any food you dislike as intensely as any medication or tonic you had to take when you were a kid. That would be classified as a superfood. I had to take a tablespoon of mineral oil a day, which is a substance very much like mucilage.

I found out that millet is marketed as a superfood. That’s funny, because it’s also used as a filling for juggling balls. When you work up an appetite juggling, you can just bust open one of the balls and snack on a handful of bird seed, which is what millet really is.

Actually, superfoods come in handy in case you’re abducted by extraterrestrials. Whenever they look like they’re getting ready to jam some kind of implant up your nose, offer them a juggling ball. Just tell them to keep chewing through the leather shell until they get to that tasty millet center. This will give you time to write down the driving directions to the nearest barbecue joint for them (Jimmy Jack’s Rib Shack in Iowa City for example).

Anytime you need any more expert advice on superfoods, just let me know. I’m not available.

Raccoon in the Mulberry Tree

I was not sure what exactly I saw this between 6:30 and 7:00 this morning shaking the mulberry tree branches in our backyard. It seemed too big to be a squirrel and I dismissed the thought, telling myself that it was most likely the usual squirrel getting its mulberry breakfast.

Just prior to this incident, I had seen and heard what I thought was a blue jay in the mulberry tree. It gave a series of short whistles while bobbing up and down on the branch. I had never heard a blue jay make whistle notes, just the usual screeches. I doubted what I saw and heard. I checked my bird book, “Birds of Iowa: Field Guide” by Stan Tekiela. It didn’t mention anything about blue jays making short whistling notes and bobbing up and down as they did so. I didn’t bother to get up and try to get a video of it. It would have been through the window of our sun room and the jay didn’t sit for more than a few seconds.

So, I looked it up on the web. It turns out blue jays make a variety of noises besides the jeer. They bob up and down as a part of a courtship ritual. They make what is termed a “pump handle call” and I found a video which duplicates what I saw and heard.

Anyhow, getting back to the critter in the mulberry tree, it turned out to be a large raccoon. It was eating mulberries and I tried to take video of it as it was climbing down the tree. This reminded me of an essay by E.B. White entitled “Coon Tree.” If you’ve ever read essays by E.B. White, you probably know already that this one is about a lot more than raccoons.

It’s basically about the conflict between nature and technology. The main essay was published in 1956 and a post script was added in 1962. The coon represents nature which White idealizes and contrasts with references to new inventions, including nuclear devices which represent the destructive side of technology.

I guess we can forget for the moment that raccoons can carry diseases like rabies and roundworm. I’m also reminded of an old TV commercial in the 1970s about margarine (an alternative to butter) in which an actor says angrily, “It’s not nice to fool Mother Nature!” The idea was that margarine (which was a new invention in the late 19th century) was healthier than the natural spread, butter—although the trans fat in it makes the comparison a bit more complicated.

White also says something interesting about unsanitary homes, claiming that children who live in them become more resistant to certain diseases like polio than the kids who grow up in clean homes. The polio scourge raised its ugly head recently in New York, which renewed the recommendation by the Centers for Disease Control recently that people who didn’t get vaccinated against polio should get vaccinated—regardless of how dirty your home was.

And then there is the artificial intelligence (AI) technology. I wonder what E.B. White would say about that? AI can improve detection of some diseases and assist in medical research. On the other hand, AI can still make mistakes and it needs human surveillance.

I read you can sometimes use loud noises to keep raccoons out of your yard. For example, you could try recordings of blue jays.

Dare to Discover at University of Iowa!

There’s been enough bad news. How about some good news? Have a look at the Dare to Discover campaign at The University of Iowa. It shines a light on young researchers who dream big. And that’s great for all of us!
