This comic is a depiction of actual events. My dear wife says the most hilarious things. I (regretfully) knew exactly what meme she was talking about. I also agree that the term she made up definitely sounds like a racial slur. We started talking about what it was a racial slur for, but discovered that was a terrible conversation and that we needed to stop.
Things are changing here. I will not be updating the blog as frequently or regularly. I was getting used to updating every week, which is fun. But I need to focus on work for a while. However, I would like to continue to upload some of these silly comics when I have a bit of spare time and inclination.
Anthony Fauci Shows Us the Right Way to Be an Expert – Scientific American Blog Network
He has done a great job. That is an impossible job.
I’ve ranted before about how the news is really not a very good use of one’s time. It’s the IMMINENT CRISIS SHOW all the time. And when they get their teeth into a legitimate crisis, it’s really hard to discern the right level of concern and the right modes of action.
The Poor and Marginalized Will Be the Hardest Hit by Coronavirus
Coronavirus is a great case in point. It’s about 10 times worse than the flu and spreads much more effectively. So we should be careful because the flu is already pretty bad for vulnerable people. Is it EbolAIDS? No. Will it disrupt essential services? Almost certainly not. Will it overcrowd a medical system where excess capacity (i.e., inefficiency) has been cut at every opportunity? Possibly. What can everyone actually do? Wash hands, social distancing.
Proof of Concept of an Iron-Iron(III)Oxide Hydroxide Battery Working at Neutral PH.
Awesome! These folks did a battery very similar to the Allen lab’s, but our current performance is considerably better. Cool.
Could curly straws hold the existentialist meaning of life? Only if you are a glass of lemonade.
Coronavirus: Do face masks work? And how to stop it from spreading?
Facemasks might prevent inhaling infectious aerosols, but that’s not how most people catch the virus. If you get the virus on your hands and then touch your face, the facemask won’t do anything.
WHO-recommended handrub formulations – WHO Guidelines on Hand Hygiene in Health Care – NCBI Bookshelf
Soap and water are the best tools to fight viruses. If a sink and soap are unavailable, then an alcohol-based hand sanitizer is an OK substitute. So I gather they are entirely sold out now. Of course. So here’s the recipe: 1 tablespoon glycerol, 3 tablespoons drug store (3%) hydrogen peroxide, and 3 2/3 cups 96% ethanol (192 proof Everclear alcohol).
It’s hard not to think about the Coronavirus. The first links are relevant to that. At the end, there’s more funny stuff. I want more people to be scientists and doctors. It’s important. Economically, our society can afford more doctors and scientists (as well as musicians, artists, etc.). We can afford to maintain a reserve army of competent people in case of a crisis. I wish we were thinking of things in terms of cost-benefit to society.
Coronavirus: US government test kits are faulty and ‘cannot be relied upon’ The Independent
We are not doing well in this fight so far. Based on the fact that they are using primers, the test is still based on the virus’s genome (rather than on the coat proteins). They say that one of the three primer sets is not performing as well as they want. The NEJM article I read only lists two primer sets. With a long infectious incubation, a good diagnostic test is important.
Structure of novel coronavirus spike protein solved in just weeks
Solving the structure of a virus and its proteins is the first step to doing lots of drug development. A structure lets medicinal chemists try to design small-molecule drugs to interfere with its function. Right now the cutting edge is to design antibodies in software to interfere with the virus, but that needs a structure to work with, too. It’s great that scientists can get to a structure so quickly.
IUB EMCenter – Electron Tomography
One of the relatively new methods for solving this kind of structures is to use electron tomography. The idea is to take images from a bunch of different angles and then use software to put all of the images together into a 3D picture. This link has some great animations of the image stack and how it looks three-dimensional to our brains.
Genetic study uncovers clues to explain how killifish stop aging during diapause
Killifish are really interesting organisms for scientific experiments. They are vertebrates, so they are closer to us genetically than insects or worms. But they are a lot easier to grow and care for then mice or rats. Some killifish have life spans of only three months. This makes them very attractive as aging model animals. If treatment extends their lifespan, you only have to wait 3 months to find out. With mice, you have to wait for several years. This paper discusses another cool feature of the killifish model animal. Some kinds of killifish can go into a kind of suspended animation. I did not know that and it is fascinating.
Nano/Microstructured Silicon–Carbon Hybrid Composite Particles Fabricated with Corn Starch Biowaste as Anode Materials for Li-Ion Batteries | Nano Letters
Researchers develop high-capacity EV battery materials that double driving range
This article discusses a new composite silicon/carbon material for hosting lithium ions. Cramming lithium ions into a silicon matrix makes for an even higher energy battery than a standard lithium-ion battery. unfortunately, silicon expands under these conditions and can destroy the battery. By incorporating the silicon into a carbon matrix, these researchers increase the conductivity and the resilience of the battery to multiple charger Cycles. The result was a very nice paper. I love that they tried to make their composite material from readily available substances.
