| Why is my water bottle pressurized after the ice melts in it? Posted: 10 Nov 2021 11:38 AM PST So I have a classic Nalgene water bottle which I fill up with ice and water everyday before work. Typically I drink 2-3 cups of coffee over the course of the morning before going for the water. Most of the time at this point the ice has melted completely. When I open the bottle the first time there is some kind of pressure action happening. I can't describe it better than it feels like the opposite of opening a carbonated bottle. My guess is that as the ice melts the water level drops and the air that is in the bottle is now stretched across a larger area creating a lower vapor pressure than the air outside of the bottle.

| How come that immunity fades away over time? Posted: 10 Nov 2021 09:48 AM PST I've learnt a lot about our immune system, but something that doesn't add up here is why immunity fades away over time. This question is kinde related to covid-19, because here they are talking about a boostershot. When you get infected, you create memory cells (T and B) which will be activated when the same pathogen infectes your body. But won't those memory cells be in our body's for a very long time? Won't they immediately bring up a immune response when activated? [link] [comments] |

| Where did the electricity for telegraphs come from during the American Civil War? Posted: 09 Nov 2021 07:25 PM PST Looking at Wikipedia, it mentions electromagnets and voltaic piles, but I don't understand how such a small amount of electricity would be able to travel the hundreds of miles needed. I can notice a reduction of power in my leaf-blower when using multiple extension cords, so how would wires from the mid 1800s be able to carry a signal from an early electrochemical battery over a meaningful distance? Edit: Thanks for the explanations and analogies, they've really helped! It makes a bit more sense now. [link] [comments] |
| How are plasma amino acids regulated? Posted: 09 Nov 2021 08:26 PM PST What controls how much of each major amino acid is available in the blood / plasma? Does eating a high-protein meal cause a spike in the levels of amino acids in the blood? Is it regulated by glucocorticoid hormones, which increase free amino acids? [link] [comments] |
| Posted: 09 Nov 2021 07:29 PM PST I've been trying to research autophagy and the conditions that encourage it, and the consensus seems to be that at least 24 hours of fasting are needed to trigger it. Why is this? It seems that autophagy provides numerous benefits that improve health therefore extending longevity; wouldn't it be more evolutionarily beneficial for autophagy to occur more frequently?

| Why do female chimpanzees live on average 7 years longer than male chimpanzees? Posted: 09 Nov 2021 08:01 PM PST Is it due to environmental fighting where males are more likely to be killed or genetics where the XX chromosome provides more genetic protection with it's redundancy [link] [comments] |
