| Posted: 30 Jan 2021 02:26 PM PST According to wikipedia, the lowest temperature on earth was recorded to -89 C at Vostok Station https://en.wikipedia.org/wiki/Lowest_temperature_recorded_on_Earth CO2 sublimates at -78 C. Was there CO2 sublimating as solid onto the ground, or even snowing down, at Vostok Station when that happened, and if so, it is plausible that layers of solid CO2 are present at the south pole. Is there any research on this? [link] [comments]  |
| What are the Criteria for a Virus Strain Graduate into a New Virus? Posted: 31 Jan 2021 12:57 AM PST I know that SARS and COVID19 are related, but why are they regarded as separate viruses and Influenza isn't? [link] [comments]  |
| If you damage receptors in your brain do they return? Posted: 30 Jan 2021 07:13 AM PST Specifically serotonin receptors (MDMA, hallucinogens) Dopamine receptors (Meth, other stimulants) GABA (benzos, alcohol) It seems neurotransmitter levels can rebalance pretty reliably, but I wonder if damage to the receptors themselves from drugs can cause a sort of permanent state of feeling terrible [link] [comments]  |
| How is genetic variation within and between human populations calculated? Posted: 30 Jan 2021 11:23 PM PST The fact that there is much more genetic variation within a population, which would previously be referred to as 'race', than between such populations is commonly used to argue against existence of races in humans. What procedure is used to evaluate genetic variation within and between populations, when used in this sense? What proportion of within group and between groups variation would be required to conclude that races exist and why? [link] [comments]  |
| Posted: 30 Jan 2021 02:55 PM PST Won't a 20% blocked coronary artery still get occluded if the plaque ruptured and was followed by a thrombotic reaction to obstruct blood flow? [link] [comments]  |
| Will the Philippines actually sink? Posted: 31 Jan 2021 12:26 AM PST I don't know if this article is real or a hoax https://www.straitstimes.com/asia/the-philippines-will-be-underwater-in-30-years-inquirer and it really triggers me if I should save enough money and move to a place where I can't be submerged in water and 'the end of the story' or not worry at all and its just a hoax.

| How does dehydration cause edema? Posted: 30 Jan 2021 12:37 PM PST so, as far as i know, dehydration means lower blood volume, which means lower blood pressure, while edema is mostly caused by high blood pressure in the veins. [link] [comments]  |
| How would orbits work if gravity wasn't inversely proportional to the distance squared? Posted: 30 Jan 2021 08:53 AM PST I just watched a video where someone tried and failed to achieve an orbit in the game Space Engineers, and a commenter said that the gravity decreases linearly in the game, resulting in "a non conservative field of force", so only a perfectly circular orbit would be stable. Another person responded to that by saying that "there are orbits in systems with linear falloff, it uses distance in a higher power". I got curious as to how would these orbits work, but i couldn't find information about them, so, what do the things in quotations mean, and how do different types of strength falloff affect orbits and trajectories?

| How is Earth’s rotation slowing down overtime? Posted: 30 Jan 2021 12:35 PM PST I understand it has to do with the Moon pulling away, so there are a bunch of follow up questions... please bear with me 😂

| How is Insulin consumed in the body after its creation ? Posted: 30 Jan 2021 12:14 PM PST I understand the pancreas creates insulin when we eat. What consumes it? What is the chemical process that removes it from the bloodstream (whether it simply decays into certain molecules, or gets transformed when it does its work with cells, or something else). Insulin's by-product, C-Peptides, are created whenever Insulin is created. Similarly, what consumes the C-Peptides? [link] [comments]  |
| How are the calories of foods determined? Posted: 29 Jan 2021 05:45 PM PST What do they do to find the calories of packaged food? Is it something someone can do with meals they cook themselves? [link] [comments]  |
| Does genetic makeup affect vaccine effectivity? Posted: 30 Jan 2021 02:51 AM PST Just a simple question on whether genes can affect the effectivity of a vaccine. [link] [comments]  |
