| Posted: 24 Jun 2021 04:15 AM PDT you can damage your skin via conduction on too hot and too cold objects (-5°C - 54 °C). Now i can somewhat understand how fast moving molecules can damage cells, but what causes the skin cells to be damaged after being in contact with slowly moving molecules? Does the water in cells and blood freeze? If so what happens to the frozen cell when thawing? [link] [comments]  |

| Posted: 24 Jun 2021 08:57 AM PDT I have always wondered if the thousands of nuclear tests that have been done have negatively affected the atmosphere or just the planet in general enough to cause worsened climate change or if they are just a metaphorical sneeze in comparison to the rest of humanity's pollution.

| Why do things float? How does having a different density actually produce an imbalance of forces? Posted: 24 Jun 2021 06:11 AM PDT When I've tried to read up on this I generally started to bump up against 'buoyance force' being introduced without any explanation of where that force has actually come from.

| How do brains use triptophanes to make serotonin? Posted: 23 Jun 2021 10:52 PM PDT Hi, so i got another serotonin question. Im working on feeding and serotonin and i've already stablished that gut serotonin is not present in the brain. Instead the brain makes his own serotonin from triptophanes that become available through eating. How the brain uses the triptophanes? They travel to the brain after ingestion? Are the same food responsible for giving the triptophanes in gut serotonin and brain serotonin? [link] [comments]  |
| Why are there areas on 30 degrees latitude south and north which are very lush? Posted: 24 Jun 2021 03:45 AM PDT For example both the south east of China and of the USA are very lush. As I understand the air descents at around 30 degrees making it warmer. [link] [comments]  |

| Can bugs such as flies and mosquitoes hear? Posted: 23 Jun 2021 02:43 PM PDT This question is from my son. I was making a show of swatting a housefly like I was a samurai, and did the "kiai yell" right before striking. This prompted his question. I told him I didn't know but would ask people who do.

| Where do most of our calories go? Posted: 23 Jun 2021 11:54 AM PDT Its clear that exercise burns calories, but where do the 2k calories our bodies burn just for being alive get spent on? Do most of them go into regulating body temperature? [link] [comments]  |
| How does alcohol effect various microbes? Posted: 24 Jun 2021 12:19 AM PDT I am currently studying a simple course, mostly focused on microbiology and chemistry, in the hopes of picking up work as a laboratory assistant or laboratory technician. Earlier in the year we learned about how alcohol effects bacteria, and why 70% ethanol is used to disinfect. Since then we have learned a lot more about microbes and today I started thinking back to those earlier lessons. From what I understand, alcohol is ambiphilic and bonds to both the hydrophobic and hydrophilic parts of the cell membrane, quickly destroying the cell. This was only explained to us in the context of bacteria. Eukaryotes also have a plasma membrane. Does alcohol have exactly the same effect on them, or do these more complex cells behave differently? Does alcohol have any effect on a virus that has not invaded a cell, or does the envelope or capsid provide them protection? In the case of a virus with an envelope I know that is a lipid, so I would imagine the ambiphilic alcohol can interact with this in some way. In the case of a virus that has invaded a cell, the alcohol would obviously have its normal effect on the cell. I imagine this would upset the virus. For example, if it were in the process of replicating the virus, but not yet ready to lyse, I imagine you would have unformed viral components that can never be brought to their finished form. From what little I know (we have barely touched on this), prions are simply proteins: does alcohol effect them in any way? [link] [comments]  |

| Why does the sound of thunder last longer than the light of lightning? Posted: 23 Jun 2021 11:24 PM PDT Atmospheric scientists and meteorologists, I need you! There is currently a thunderstorm above my head. There is lightning, but it's not making ground contact. What I noticed is that, while the light from the lightning may last .2 seconds, the sound from the thunder lasts upwards of 8 seconds. Why is this? Here is my theory: lighting is not a single point phenomenon. It is arcing over a distance, and based upon the length of the sound of lighting we can guess the distance of the arc. So if thunder persists for 8 seconds, and the speed of sound is 1100ft/second, we can assume the arc had a distance of 8800ft (assuming I were directly below the point where it started and it traveled in a horizontal line). Is that why thunder sticks for so long? Is it just the speed of sound through the atmosphere? [link] [comments]  |

| Posted: 23 Jun 2021 06:18 PM PDT A friend told me he believes it is just as hard to breathe at his home in Georgia as it is for him at altitude because of how humid it is. Is there science to support this? Edit: my friend in GA lives at about 300ft above sea level. I did find that air density is effected by humidity but it doesn't seem to be nearly as significant as altitude's effect. [link] [comments]  |
| Posted: 23 Jun 2021 10:02 AM PDT My understanding is that dirt comes from a mix of organic material and small rocks/sand/etc. But does this mean earth didn't have dirt before small plants evolved? I live in a really cliffy area and I was always wondering how moss can manage to grow on cliffs and how they extract the nutrients. [link] [comments]  |
