How are inactivated vaccines produced? |
- How are inactivated vaccines produced?
- Did Theia actually smash into the Earth or is Earth a combination of Theia and some other pre existing body?
- If you catch a cold, is there an easy way to know or guess which virus is causing it?
- Assuming reaching absolute zero was possible, how much pressure would H2O at 0K need to be under to be a liquid?
- Why can't adenovirus-vectored vaccines be aerosolized so they don't require needles?
- Why do people only have 10 seconds of useful consciousness at high altitudes when most can hold their breath for at least 30 seconds?
- Is the conversion efficiency from fuel to electricity better in gas/oil power plants compared to car engine?
- In North America there are often invasive species from Asia, such as The Spotted Lantern Fly. Are there invasive and pesky species from North America on other continents?
- Can anyone explain this phenomenon?
- What is the physics behind compound bows and compound crossbows?
- When determining vaccine efficacy/effectiveness, is there a point made to distinguish the prevention of infection vs prevention of serious illness?
- Is a "well exercised" immune system better at fighting off an unknown pathogen? Or, conversely, can an immune system be too well exercised?

| Posted: 22 Oct 2021 12:47 AM PDT The main theory for how the Moon, Luna, formed, is that a Mars-sized protoplanet named Theia collided with another protoplanet, and the ejecta coalesced into the Moon. But not all of Theia could have become the Moon, Mars has the mass of 6.39e23 and the Moon has a mass more than ten times that, and so it must have radically changed the protoplanet too, becoming more than 10% of the thing. Wouldn´t Theia hitting it have actually formed Earth as we know it and we are just a merger of the two? [link] [comments]  |

| Why can't adenovirus-vectored vaccines be aerosolized so they don't require needles? Posted: 21 Oct 2021 09:01 PM PDT Whether through a nasal spray or inhalation, it seems like there would be less vaccine hesitancy if there was a route of administration that didn't require needles.

| Posted: 21 Oct 2021 10:28 PM PDT On average people are able to hold their breath for 30 seconds, but in the event of rapid decompression at high altitudes (40,000ft) they will become useless after just a few seconds. Why is this? [link] [comments]  |
| Posted: 21 Oct 2021 01:30 PM PDT Conversation that I had with a friend. With electric/hybrid cars being more common, we talked about why should we switch to electric cars when the electricity needed to power the car would still need to be obtained from gas or oil power plants? As I type this, I realised that electricity for the cars can also be obtained from renewable energy sources. But the question still stands. Does the amount of energy obtained from burning gas/oil in a power plant have a higher yield than if we were to use the fuel directly in a car. Also, I saw a reddit post/news that said that a state in the US is banning gas powered lawn mower. The same question but this time the comparison between a gas powered lawn mower and gas/oil power plant. P.S If there is another post that had already answered this, I would love to read it. Just didn't know how to word it succinctly to search on reddit. Thanks in advance! [link] [comments]  |

| Can anyone explain this phenomenon? Posted: 21 Oct 2021 09:00 PM PDT This bottle of Croatian rajika keeps opening back up whenever I put the stopper in. I have never seen this before with something that's not carbonated. Genuinely curios if it's yeast or some other sort of gas being released from the fermentation process. Thanks for the help!

| What is the physics behind compound bows and compound crossbows? Posted: 21 Oct 2021 04:25 PM PDT I get that it uses a pulley system to transfer the force to the arms of the bow, but I can't find anything that goes in depth into the physics behind it (ideally with figures). Does anyone know or have a link to how the actual physics/engineering works? Like with numbers and equations to go along with the explanations and all that jazz [link] [comments]  |
| Posted: 21 Oct 2021 10:26 AM PDT For example, Pfizer recently stated that a 3rd shot of their vaccine would restore a 95.6% efficacy against COVID. I assume that means that it is extremely unlikely for me to ever catch COVID to begin with. But I wonder, is there another number associated with the efficacy against serious illness? Like say Pfizer is 95.6% against initial infection but 99% against serious illness? [link] [comments]  |
| Posted: 20 Oct 2021 06:22 PM PDT By "exercised" I mean exposure to many different pathogens, although not necessarily ones closely related to a new pathogen. By "too well exercised" I don't mean in the short term, while actively fighting off an infection, but could there be such a thing as too many different kinds of T-cells or anything?
