What happens to the lungs after death? Posted: 06 Jan 2022 09:13 PM PST Do bodies really exhale like on TV? Can you die with a full breath inside your lungs? If you can die with air inside, how long does the remaining air last? Does your diaphragm need to move to empty the lungs? submitted by /u/tokensmoker [link] [comments]

Do my thoughts feel like they come from my head because I know that's where my brain is? Posted: 06 Jan 2022 06:59 AM PST Or have inner monologues always felt like they're in our head? And of that's the case, isn't it obvious that your brain is the originator of thought? Why did it take Alcmaeon of Croton to come along and tell us all the brain is where thought comes from? I asked this question yesterday on another sub, but I feel like this sub might be more appropriate. submitted by /u/UsernameNumberThree [link] [comments]

Will filling up your car tank with gas when it's cold get you more gas when it gets warm and expands? Posted: 06 Jan 2022 09:50 AM PST Someone told me this, and consumer reports https://bit.ly/3pZ8mel says it's negligible. I thought, if you added the same liquid volume of gas, even if it expands, doesnt the same total energy remain? submitted by /u/Jucarias [link] [comments]

With FM (frequency modulation), how can radio channels not get mixed up if the information is contained in the variation of the frequency? Posted: 06 Jan 2022 08:03 PM PST If I set my radio to 90 MHz, I think the frequency of the signal must vary around that frequency to carry information. Don't the 90 MHz and 89.9 MHz signals mix because of this variation? Or are they confined to a narrow band? submitted by /u/ucusansinekler [link] [comments]

Is road salt significantly affecting the environment? Posted: 06 Jan 2022 08:32 AM PST Every winter my city is constantly spreading salt on every driving surface. This is of course happening in every cold weather city. It seems like a ridiculous amount of salt that gets washed down the storm drain every year. Is this significantly affecting the streams, rivers, and oceans? Is the salinity of the ocean growing by any significant margin? Are there other environmental affect I'm not thinking of? submitted by /u/goharvorgohome [link] [comments]

Can the immune system generalise antibodies? Posted: 06 Jan 2022 02:30 AM PST I know the immune system can create antibodies specific to an antigen, but I was wondering if it makes less specific antibodies as a preventative measure, or as a side effect of producing specific antibodies submitted by /u/NocturnalFiend [link] [comments]

What is 'Excited Delirium' and how can you die from it? Posted: 06 Jan 2022 03:14 PM PST I got on a 'police video' binge recently and I must have watched 5 or more videos where a person dies (seemingly) from just being bound/restrained/handcuffed. They seem to go from alert and awake, to unresponsive and not breathing in a matter of just 2-3minutes. Has anyone studied 'Excited delirium'? Is it possible for a human to die if they have too much 'lactatic acid' or 'lactate' or maybe even adrenaline in their system, and then are restrained, so their body can't 'burn it off'? submitted by /u/LFP_Gaming_Official [link] [comments]

How do GPS satellites stay in geosynchronous orbit as the Earth goes through it's yearly tilt back/forth cycle that makes the seasons? Posted: 06 Jan 2022 10:29 AM PST Do they have to burn fuel to do this? How much fuel and since they are so far away how far do they have to travel to stay in geosynchronous orbit. Or do they have something built into the GPS protocols that accounts for the Earth's yearly tilt? submitted by /u/sweaterJana [link] [comments]

It's been almost 2 years, how effective are lockdowns really? Posted: 06 Jan 2022 09:15 PM PST Since it's been quite a while, there has probably been a good amount of time to collect data on this. What does the literature say about the efficacy of lockdown measures on controlling the spread of the disease? How have lockdown measures panned out differently in other countries? What specific measures/restrictions seem to be more effective than others? (i.e. are gyms or schools more dangerous for the spread of the disease) Maybe this data won't be as relevant with the recent prevalence of the omicron variant, but what does the data say now? submitted by /u/TheGetDown_ [link] [comments]

(Statistics) How do you separate out two factors integrally related to one another? Posted: 06 Jan 2022 07:28 AM PST In this study https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5383251/ the authors analyze increased dementia risk associated with antidepressant usage. However, the rub seems to me to be that depression itself is associated with dementia risk. And the other things antidepressants are used for--anxiety, insomnia--also have higher independent dementia risk. The paper acknowledges this confounding factor and then says they do some kind of statistical magic to get around it. How does this work? How do you get around a confound like this? submitted by /u/steveloafworld [link] [comments]

What would the major differences be between the coastlines of today and 12,000 years ago? Posted: 05 Jan 2022 08:27 PM PST I know the continents had all reached their modern locations by that recently, but I also know that there were a few major differences, like Britain still being connected to the continent via Doggerland and much of the Persian Gulf was still above water. What other geographical differences would we have seen then before the agricultural revolution? submitted by /u/MarcMercury [link] [comments]

Why don’t people get Covid again within 90 days of a previous Covid illness? Posted: 05 Jan 2022 10:05 PM PST Everything I've seen - including information on my state's testing site - says that you are basically immune to Covid for 90 days after having it. I'm curious about several questions relating to this: Is this true? Since people are discouraged from testing within 90 days of the initial start of the Covid illness due to false positives (an issue with PCR mostly, from what I've heard), is it possible/ probable that people are getting reinfected again within this time, but are not aware of it due to lack of testing. Will omicron change the likelihood of reinfection within this 90 day window? Omicron is quite different from the previous viral strains - will the mutations on the spike protein enable it to dodge recent post-infection antibodies as well as it apparently dodges vaccine antibodies? submitted by /u/bird-nird [link] [comments]

What is caffeine's use in nature? Posted: 05 Jan 2022 07:55 PM PST So I know we as humans use caffeine as a stimulant but what is it's original use in nature, what I mean is what does the plane use it for, as a defense mechanism? or is it used to help make a symbiotic relationship with creatures? i.e. an animal eats something with caffeine giving it energy causing it to come back to the plant and spread seeds/pollen. submitted by /u/Accomplished_Kale670 [link] [comments]
