so it makes a bunch of blood clots waiting to happen? damn

They can by eating, like fish that never see the sunlight. Grass also contains Vitamin D.

Another theory is that many birds and Mammals get their vitamin D from excreated oils which then are ingested while grooming themselves.

I also found a study where cows where covered and produced way less vit D, so it's definitely skin as well. Just because an animal is covered in fur, doesn't mean 0 sunlight reaches the skin.

How would competition work in the first place? Unless so many cells are already infected that virus #2 can't find any to reproduce?

> "do you need supplies? ...please?".

That is very funny, while also an indication that things along the lines of "yearly vaccination that a country needs" probably should be nationalised lol

Was that the prediction though? Seems like a virus that's just jumped a species gap has a lot of easy optimisation available. What I was seeing in my academic circles was the expectation that the first version would be replaced fairly quickly

I think part of the reason it seemed unusually stable was that it was operating in basically a vacuum for immune evasion pressure. Every host was a naiive one without prior covid exposure. There was therefore not as strong of a selection pressure as the other coronaviruses were under to evolve new variants that could evade prior immunity. Once you get that selection pressure, the number of apparent new variants ratchets up quickly, because anything that isn't new can't spread effectively in our high-immunity environment.

It's a good question! Humans as apes are more genetically similar to other apes than tailed monkeys, and that small difference (e.g. 1-2% of dna) has a huge impact on development. When animal research is carried out there is lots of preparation with model cell lines, organoids, tissue cultures, etc., before you get to the actual animal in the cage. With all that effort put into preparation, you want the final animal samples to be as close to human samples as possible.

Other simians also have different diets, microbiomes and are susceptible/resistant to different diseases than humans, which could definitely affect your immunology experiments.

However, the scientific benefits of using our closest relatives (i.e. humans, chimps and bonobos) is outweighed by the ethics of using highly intelligent and emotional organisms for research when alternatives are available. Ultimately, this is a socially constructed limitation but it's one I agree with. Also, it is very very expensive to raise great apes in captivity, which means research budgets can't cover it. Imagine raising a 60kg human with emotional problems that can bench 150kg for years just to cut it open and look at its colon. That's not worth it.

I thought you also can have multiple rhinoviruses at the same time too. Is that right?

Earthquakes also cause soil liquefaction (sinkholes), landslides, and in some cases tsunamis. It also frequently cases sewage backflow and flooding. All of which kills people without toppling buildings.

Architect here, aside from the comments already added here, it is important to point out that the scale of devastation in human population in an earthquake is most often due to the designed limit of buildings (environment) to be able to withstand the forces.

In other words. Earthquakes alone don’t kill people, earthquakes topple buildings which then in turn kill people.

At 25°C, Silver (Ag) = 10.49g/cm^3 and Mercury (Hg) = 13.53g/cm^3

Given this, at STP (25°C, 1atm) Ag would be solid and Hg would be liquid. Therefore they would not be mixing into a solution. I assume these facts to be evident, but I am stating them just to be safe.

Since Ag has a lower density than Hg, the Ag would float on the Hg.

If you have any follow up questions, I will be glad to answer.

I think this is the most revealing thing about the covid lockdown. I am a hospital pharmacist and we noticed that the traditional flu season did not take place to any appreciable degree. It is not realistic to adopt these extreme measures moving forward, I just hope at the very least people gained a little more insight into the pathology and transmission of communicable disease.

A small percentage of people who are tested have their sample sequenced as well.

If a lab performs 250000 PCR tests a week and gets 20000 positives, it will likely sequence 100 of the positives.

This then shows trends across the population in which variants are dominating.

Earthquake causes many issues other than the shaking. You have Soil liquefaction, landslide, fractures. Any of those can cause them to get burried and or squished. Although it is true that the biggest danger comes from your environnement collapsing. So you can’t really state a level. If you stand on a plain field i believe that even the strongest earthquake would not cause you any harm.
