Surprising that anyone still thinks the Penrose model could work. Microtubules do not exhibit harmonic motion like violin strings. The reason is that all motion at the length scale…

Lossy compression is a bad idea for scientific images. For instance, we often need to understand the statistics of photon detection events in background regions. That’s one of the …

It wasn’t entirely clear in the parts that I watched, but my understanding is that slime molds are actually “social” amoeba. They often crawl around as loners, eating whatever they…

3% CO2 from mask wearing? I doubt it. I recently needed to measure 5% CO2, and I had to hold my breath to near-passout levels to reach 5% on the monitor. There’s no way that I coul…

Bit flips from cosmic rays. Earth’s magnetic field helps to shield us, but is disrupted now. I work with a CCD camera in a sub basement lab. On a normal day we see a stray cosmic r…

He saved all seven shots against, if I recall. And one of them he stood on his head.

Generally, the reverse complement of a translated sequence is uninteresting. The function is not encoded in the reverse complement.

Exponential growth easily crushes any attempts to surge capacity.

Note that MDPI is a predatory journal. @dang, this is not from nih.gov, you might want to fix that.

You’re right. Some of us only realized our mistake when it was too late.

Certainly. For me it started when they removed the entire scientific stack, which broke my install scripts / brewfile. Then, they removed the ability to customize builds, which bro…

One vote in favor of macports here. I first went from homebrew to nix. Nix was fine, the concept is great but I found the language to be difficult. Ports is closer to homebrew in i…

The polyA tail is in the 3′ UTR (after the stop codon) and is not translated. It doesn’t appear in the final protein sequence. It’s also a fairly standard feature.

Given the two dozen or so known causes of myocarditis, the vaccine does not stand out here. The risks of complications from the virus do stand out, in stark contrast.

There is no spike protein in the vaccine. There is mRNA. That mRNA needs ribosomes to make the spike protein. So think about where there are ribosomes, and where the protein is mad…

The vaccine produces spike protein within your deltoid muscle cells, where it is rapidly degraded and presented to your immune system. It’s not running around in your bloodstream. …

Tungsten beads are also popular as a weight for fly fishing nymphs due to their density.

In addition, in April we didn’t have the delta variant in the US.

Transcription causes mutations in the spike that causes clotting issues? Do you have any idea how much transcription happens in your cells, every moment of every day? You need to r…

As does the virus itself. Many, many ingredients.

One of the major things that keeps me in Emacs is the keyboard macros. Being able to record a key sequence is something that I use regularly, and I don’t think the major competitor…

I guess it’s a good thing that the vaccine makes spike protein within your deltoid muscle cells, so it can’t float over to your brain. And it all gets quickly degraded anyway.

You might have some sort of dangling config issue somewhere? I use the emacs keybindings in the Julia REPL all the time. They work fine out of the box (at least here).

The flag on this article is unwarranted. Derek’s analysis is excellent.
