How do lungs heal after quitting smoking, especially with regards to timelines and partial-quit? Posted: 02 Sep 2021 09:56 AM PDT Hi all, just trying to get a sense of something here. If I'm a smoker and I quit, the Internet tells me it takes 1 month for my lungs to start healing if I totally quit. I assume the lungs are healing bit by bit every day after quitting and it takes a month to rebuild lung health enough to categorize the lung as in-recovery. My question is, is my understanding correct? If that understanding is correct, if I reduce smoking to once a week will the cumulative effects of lung regeneration overcome smoke inhalation? To further explain my thought, let's assume I'm starting with 0% lung health. If I don't smoke, the next day maybe my lung health is at 1%. After a week, I'm at 7%. If I smoke on the last day, let's say I take an impact of 5%. Next day I'm starting at 2%, then by the end of the week I'm at 9%. Of course these numbers are made up nonsense, just trying to get a more concrete understanding (preferably gamified :)) . I'm actually not a smoker, but I'm just curious to how this whole process works. I assume it's akin to getting a wound, but maybe organ health works differently? I've never been very good at biology or chemistry, so I'm turning to you /r/askscience! submitted by /u/Monster-Zero [link] [comments]

Can and how protons fuse? Posted: 03 Sep 2021 07:13 AM PDT The question is simple, what happens when two protons overcome Coulumbs barrier? Do they fuse and make some sort of a hadron? Or do the 2 protons stick to eachother making a sort of nuclei? Or does something else happen? submitted by /u/Meidlim [link] [comments]

In space, is it as 'easy' to accelerate an object from 90% the speed of light to 91% as it is to accelerate an object from 10% the speed of light to 11%? Posted: 03 Sep 2021 03:17 AM PDT Is it more difficult to accelerate an object to faster speeds in space like it is on earth? On earth, to go from 20-30mph is much easier than to go from 220-230mph. In the absence of air resistance and engineering limitations, what are the limiting factors, if any, to reaching higher speeds? submitted by /u/kendo545 [link] [comments]

How do cross-ocean communication cables deal with canyons? Do they lower it all the way down, across the floor and back up or would they allow it to gap across? Posted: 02 Sep 2021 10:16 AM PDT submitted by /u/TheClayroo [link] [comments]

Can removing wisdom teeth change the shape of your face? Posted: 02 Sep 2021 05:20 PM PDT And does each removal change it differently. Like if you removed the lower ones would your jaw shrink and if you removed the upper ones would your cheekbones shrink? How else should the bones heal without absorbing surrounding bone mass. submitted by /u/cunny_man [link] [comments]

Is everyone's digestive tract the same length? Posted: 02 Sep 2021 03:45 PM PDT I mean 2 people who are the same height and size. Does this play into different levels of nutrient absorption? submitted by /u/pillowwow [link] [comments]

What is the actual mechanism behind the symptoms that are caused by trisomy? Posted: 02 Sep 2021 07:16 PM PDT I'm not thinking of any specific chromosome but for example let's say trisomy 21. What is about having a third 21st chromosome that affects the person in that particular way? submitted by /u/0dysseus123 [link] [comments]

Do large structures inhibit tornadogenesis, such as in urban centers? Posted: 02 Sep 2021 06:48 AM PDT As tornadoes are a rotating column of air that gets pushed toward the ground, would it coming into contact with skyscrapers and other large structures such as a city center cause enough turbulence within the mesocyclone to inhibit or at least weaken a burgeoning tornado? Additionally would a developed tornado hitting a large urban center be significantly weakened as it passed through? submitted by /u/tyler1128 [link] [comments]

Could an asteroid theoretically approach the earth so fast it isn't detected? Posted: 02 Sep 2021 02:47 PM PDT Is there a maximum speed an asteroid could travel?

Is it possible to build immunity to nettles ? Posted: 02 Sep 2021 04:17 PM PDT Hi I am 15 and living in Scotland I was I get exposed to nettles a ton because I like to go fishing mainly fly fishing at very hard to access places with a lot of nettles today I walked through a massive bush of them and I was wearing shorts my legs were fine but the only stings that hurt were the ones on my hand so did my legs evolve immunity to nettles or is there another reason behind this and also will prolonged and frequent exposure To nettles harm me in any way submitted by /u/Connormclean3 [link] [comments]

Do humans experience any cycles like the 24h circadian rhythm, but with different frequencies? Posted: 02 Sep 2021 04:16 PM PDT For example, episodic cluster headache sufferers often get episodes cyclically at extremely regular intervals. Each episode may happen once every 90 days, or once every two years (in my partner's case), or at apparently any arbitrary frequency. And within each episode, the headaches may happen once a day at the same time (even almost the same minute), or every 4 hours, and so on - again, the frequency appears to be arbitrary. What could possibly be causing this? Are there multiple cycles of different frequencies in the body which might all "peak" at once, causing a headache? (Knowing cluster headache sufferers and having read quite a bit on it, I do not believe the episodes are somehow psychosomatically induced. The headache results from the activity of the trigeminal nerve, and certain drugs (triptans) and other methods (oxygen therapy in particular) very reliably abort the headaches, apparently by inducing vasoconstriction.) submitted by /u/Cannabat [link] [comments]

Does surface tension get weaker as the temperature of a fluid increases? Why? Posted: 02 Sep 2021 11:51 AM PDT I can't explain this, it just feels intuitive, but it seems to me that the surface tension of a fluid becomes weaker if that fluid gets hot. I'm hesitant to call it a rule or something though because I can't explain it. Is that a real thing, and if so, why does it happen? submitted by /u/SnugFnuggBlue [link] [comments]

AskScience AMA Series: I'm Jon Schwantes from Pacific Northwest National Laboratory, and my team is working to uncover the origin of uranium "Heisenberg" cubes that resulted from Nazi Germany's failed nuclear program. Ask me anything! Posted: 02 Sep 2021 04:00 AM PDT Hi Reddit, this is Jon Schwantes from PNNL. My team and I are working to uncover one of history's great mysteries. During WWII, the United States and Nazi Germany were competing to develop nuclear technology. The Allies thwarted Germany's program and confiscated 2 inch-by-2 inch uranium cubes that were at the center of this research. Where these cubes went after being smuggled out of Germany is the subject of much debate. Our research aims to resolve this question by using nuclear forensic techniques on samples that have been provided to us by other researchers, as well as on a uranium cube of unknown origin that has been located at our lab in Washington for years. I'll be on at 10:30am Pacific (1:30 PM ET, 17:30 UT) to answer your questions!

Do electromagnetic waves decay? Posted: 02 Sep 2021 06:26 AM PDT A friend sent me this cool video recently. It shows how a parabolic dish can turn a wave originating at its focus into a highly directional pulse. The pulse appears to remain self-contained without spreading out as it travels. This made me wonder. How far will this directional wave travel in a complete vacuum? To me, it seems that such a transmitter -even with perfect geometry and reflection- would not have an unlimited range. But most EM waves 'decay' due to the inverse-square law, where their amplitude is attenuated as the wave spreads outwards in all directions. That is clearly not happening here, so what factors would limit the range of this transmitter? If I had to guess, I would say that the electrical permittivity and the magnetic permeability of empty space would be the factors that limit how far a wave (that is ignoring the inverse-square law) could propogate. But I'm not %100 sure. What do you guys think? submitted by /u/ManlyMcBuff [link] [comments]

have there been cases of people getting vitaminosis of fat-soluble vitamins from rapid fat loss? Posted: 01 Sep 2021 06:33 AM PDT Fat-soluble vitamins such as retinol are stored in the body's fat tissue. During weight loss, if done right, one should expect to see body fat reduce; does this release all the fat-soluble vitamins stored in there? Has this ever caused vitaminosis because it was done too rapidly? submitted by /u/dareealmvp [link] [comments]

What other "long overdue" disasters are there? Posted: 01 Sep 2021 07:42 AM PDT So we finally got the global pandemic.

What kind of protection do memory T cell stored in bone marrow provide, compared to neutralizing/sterilizing immunity? Posted: 01 Sep 2021 11:59 AM PDT There's lots of discussion around the vaccines providing the best source of sterilizing immunity, but what protection could be provided from these memory T cells from natural infection and the following convalescent immunity? And do vaccines also provide this same type of immunity, or only sterilizing immunity? submitted by /u/GlossyEyed [link] [comments]

How powerful a telescope would you need to be able to see something like the lunar rovers or old landing sites on the moon? Posted: 01 Sep 2021 08:53 AM PDT Would we be able to see anything at all or would the atmosphere be a problem? Thank you! submitted by /u/_haha_oh_wow_ [link] [comments]

How well do amputated limbs 'work' after they've been reattached? Posted: 01 Sep 2021 09:09 AM PDT Say someone had a hand sliced off, and all of the circumstances were ideal for them to get it put back on (say the accident happened in the middle of a well funded hospital with experienced surgeons on staff). If this hand gets attached, will the person be able to have the same kind of dexterity in their hand/fingers as they did before the accident? submitted by /u/Raspint [link] [comments]

Why didn't the Y-chromosomal Adam and Mitochondrial Eve spawn around the same time? Posted: 01 Sep 2021 01:37 AM PDT I have to admit that I have a religious bias when asking these questions, so I'd love for you to untangle that if needed. But my question is that, why didn't the Y-chromosomal Adam and Mitochondrial Eve spawn around the same time? Like wouldn't the mother (Eve) and father's (Adam) genetics carry to all humans if all humans hail from the same ancestors? So would they be alive at the same time (when the ancestors were alive)? To bring the religious side to it: Assuming that Adam or Eve was the Y-chromosomal Adam or Mitochondrial Eve, when Adam and Eve had children, and their children bred with other humans, human like species and etc, and all humans hail from Adam and Eve. Would this case would this be the Y-chromosomal Adam or Mitochondrial Eve? In my mind it would seem to be both, but I have a limited understanding of genetics to know if this is true or not. I watched this video talking about it a bit, but only mentions Mitochondrial Eve, but not Y-chromosomal Adam, is there any reason why that is? Is the former more important than the later? submitted by /u/Mohk72k [link] [comments]

What decides the initial shape of the shape-memory alloys? Posted: 01 Sep 2021 06:49 AM PDT https://youtu.be/65r6Ztxi0EQ I saw a video(link above) on how nitinol works, and the video creator explained the shape-memory ability of the nitinol alloy. He had a spring made of nitinol and then he deformed that spring using power, after that he showed how by using water, heat, or electricity we easily get that spring back to its initial shape. My question is that what or which process/component decides what that initial shape is going to be that we will get when we apply heat, water, or electricity to a shape-memory alloy like nitinol? submitted by /u/Smitmachhi [link] [comments]

Why after osseointegration skin does not "stick" to an implant?

Are there physiological or psychological differences that can cause people to perceive colors very differently? Posted: 31 Aug 2021 09:52 AM PDT So most of my peers (26 y/o and older) don't have a "favorite color". I've personally always found this odd because for me, red is very clearly the "best" color. And I dont mean that as its the color I personally like best from an aesthetic point of view. The best way I can describe it is that I can almost perceive red better than I can another color like blue. It just seems so much more vivid. I've taken color blindness tests and what not and I believe I have "normal" color vision. But I swear that the color red just always feels, in a sense, more real to me. This came up with some friends recently when a scene in a movie came on where one character asked the other what their favorite color was. He quipped back blue, and the original character pointed thats a lie because adults don't really have a favorite color. It struck me as almost odd, and in talking with my friends more, I was surprised they didn't feel the same way as me. So I suppose my question really is... are there any physiological or psychological differences that can cause someone to perceive a color very differently from other colors? Or is this purely something I've somehow only imagined? submitted by /u/ChrisGnam [link] [comments]

What do we know about Covid transmission while outdoors amongst vaccinated people? Posted: 31 Aug 2021 04:48 PM PDT I've searched google scholar with no luck.

Can a large traveling object in space affect stable bodies which contact their Roche limit? Posted: 31 Aug 2021 11:05 PM PDT Scientifically speaking, is it possible for a passing asteroid or other large body traveling in space, with it's own Roche limit, tear a piece away of a smaller stable body in a solar system through tidal force pulling? I'm not talking solely about Earth, but any stable body in natural orbit around another body. If a larger body traveling freely in space, with a larger mass and gravitations pull, tear parts away if the larger body passed the smaller and the smaller moved inside its Roche limit? submitted by /u/kellogchkt912 [link] [comments]

How bright is a starry night? Posted: 31 Aug 2021 08:05 PM PDT Assuming no other light sources (human light pollution, moon, etc.) Essentially, how many Watts of visible spectrum light will be captured by a 1m2 flat surface in outer space? Would the atmosphere change this result by much (visible spectrum). And how that amount of brightness compares to a 60W incandescent equivalent in an ordinary 100 sqft room? By the way, my assumption is that the stars would be the main source of light under a starry night. Let me know if that is not the case. submitted by /u/nhremna [link] [comments]

Do all people with synesthesia associate the same things together? Posted: 31 Aug 2021 12:33 PM PDT Like when they taste the same food and see a colour, would it be the same colour?

Is Fusion for Energy Production or Weapons? Posted: 31 Aug 2021 04:59 PM PDT I follow science in general and have a strong laymen's understanding of nuclear energy; whether it's green energy or not, whether it's feasible to resource or not, whether it's safe or not. All of these questions can be searched and understood by a bystander... for fission. However, I read this article on fusion recently: Has Fusion Really Had Its "Wright Brothers" moment You'll see as you read through it that the field expert answering the questions has the opinion that fusion was only ever going to be for weapons. That the decision to call it the next big energy source was more to get funding and keep our knowledge of fusion up incase we needed fusion bombs. My question is, does anyone in this community have more insight into the truth of Fusion energy? Will it ever be free energy, or is it the case that it's only good for nuclear bombs? submitted by /u/BigbunnyATK [link] [comments]

What is the smallest living thing that can heal external wounds? Posted: 31 Aug 2021 08:55 AM PDT Like how if a human gets a cut they can heal and it will scab over and eventually be fine.

Is cryptocurrency really that bad for the environment? Posted: 31 Aug 2021 02:29 PM PDT It seems these days like every time I see a discussion on social media about cryptocurrency/NFT/blockchain tech, there's at least one person accusing the rest of burning down rainforests. I've been hearing a LOT that cryptocurrency is uniquely bad for the planet and nobody who cares about climate change should use it. The argument, as best as I can tell, is that mining cryptocurrency/keeping a blockchain up to date requires a lot of computing power, which requires a lot of electrical power, which thus results in more fossil fuels being burned and thus more emissions--all in the service of a hobby that adds nothing real or valuable to the world. Which isn't *wrong*, but... isn't the same true of TikTok? Movie streaming, gaming, porn, social media--there are a LOT of frivolous things that consume huge amounts of computing power/electricity and don't have nearly the same reputation for environmental harm. Am I missing something? Is there a secret side effect that makes blockchain uniquely terrible? Or are there better places to focus our climate-change efforts? submitted by /u/Yeah-But-Ironically [link] [comments]

How does a vaccine applied via adenovirus produce a response without affecting your DNA? Posted: 31 Aug 2021 02:54 PM PDT Bear with me as I am a definite layman. I have an undergrad 100 level grasp of biology. I already understand how an mRNA vaccine is unable to affect your DNA, but my understanding is that an adenovirus application will inject whole DNA (not mRNA) into a cell nucleus, is this correct? From there, what mechanism allows it to help develop the immune response and what mechanism doesn't allow it to alter your DNA? I feel like these days you need to make disclaimers or else people automatically lump you into predefined boxes. I am not at all anti-vax. I have noticed (from family members unfortunately) that a lot of anti-vaxxers keep bringing up "expiramental gene therapy" as a big scary expression without any explanation of what the hell they are talking about or why it's some big government secret. My limited understanding of gene therapy treatments that do exist is that if they were able to implement an effective gene therapy drug at the price and with as few side effects as the Covid vaccines that it would be a huge breakthrough that they would be very proud of, not trying to hide. submitted by /u/cheapseats91 [link] [comments]
