Can prions from contaminated meat remain on cutlery, dishes, pans etc, after contact with them? Posted: 08 Jan 2022 08:17 AM PST I read that iatrogenic cjd can be transmitted through contaminated surgical instruments after contact with contaminated tissue, so can variant cjd be transmitted in this way, but through the kitchen utensils that were used to cook this meat? For example, if contaminated meat is cooked in a frying pan, and later normal meat (or any other food) is cooked in the same frying pan, will this normal meat get infected through the frying pan? Will prions from the contaminated meat remain on it? submitted by /u/vhiugnk [link] [comments]

Why is Covid testing so much easier than a year ago? Posted: 08 Jan 2022 06:39 PM PST Originally to get tested you had to stick the swab like 2 inches into your nose. Now you can just swab around the opening. Has tests gotten better, or were we just not great at understanding how Covid works so sticking it really far up you nose was a cautious measure to ensure accuracy. submitted by /u/JayKayne [link] [comments]

How do we age living trees without cutting them down? Posted: 08 Jan 2022 10:35 AM PST I'm curious on this, as the two forms of dating I know are tree rings, which require it to be cut down, and carbon dating, but as they're still alive I'm not sure this would work. submitted by /u/ReggusAttor [link] [comments]

Is energy conserved in the redshift of cosmic microwave background (CMB) radiation? Posted: 07 Jan 2022 05:45 PM PST If I understood correctly, the CMB originated at a time when the universe was much hotter and denser than today, and originally consisted of photons of much shorter wavelength than today. As the universe expanded and cooled, the photons comprising this background radiation did too, and at present it appears to us in the microwave range of wavelengths. I don't understand how the law of conservation of energy holds for the total amount of energy carried by the CMB. The number of photons comprising the CMB can't increase. It can only remain the same or decrease (some photons will get absorbed by matter), and their wavelength is continually increasing. The total amount of energy carried by the CMB should therefore decrease (photons will longer wavelengths have less energy). If energy is conserved, where did this energy go? submitted by /u/phlogistonical [link] [comments]

What might cause the creation of many waterfalls (in a hypothetical world)? Posted: 08 Jan 2022 03:33 AM PST Just theoretically, what properties would an ecosystem/planet need to have for the creation of a large number of waterfalls?

Is there real-world data showing boosters make a difference (in severity or infection) against Omicron? Posted: 07 Jan 2022 06:21 AM PST There were a lot of models early on that suggested that boosters stopped infection, or at least were effective at reducing the severity.

How would a nuclear explosion in space differ from on the earth? Posted: 07 Jan 2022 09:25 AM PST I'm just wondering if vacuum of space and lack of gravity would change the explosion? I'm guessing because of the conservation of energy, more of the energy would be released as light or other electromagnetic waves, than a similar explosion on earth, where the energy is also distributed as sound waves, heat conduction, kinetic energy (moving rock / earth), etc. Is that right? and would there be any other major differences?

Where do animals with no bones and circulatory systems generate their blood cells? Posted: 07 Jan 2022 05:05 AM PST Mammals, and I'd imagine other animals with bones, have evolved such that we produce red blood cells in our bone marrow.

Is it possible to identify blood cells in (zebrafish) embryos using a modified version of blood smearing? Posted: 07 Jan 2022 09:54 AM PST Context: I am a high school student partaking in AP research. For my topic, I wanted to see if blood cell presence is affected during hair cell regeneration in zebrafish, which are well-known for their regenerative capabilities. My initial method was to take blood from adult zebrafish, but that would result in fish genocide. My second method was to use fluorescent dye so I can look under a microscope and visibly see changes in the blood components, but the materials are notoriously expensive and I do not know what material can identify both red and white blood cells. My third method, and current, method is to use the blood smearing method, but with zebrafish embryos. Instead of smearing blood across a film, zebrafish embryos can be distributed on it instead. Hemastain will then be used to mark the red and white blood cells. Is this method feasible? submitted by /u/Einescii [link] [comments]

Can Eurotium Cristatum induce THC-like psychoactive effects? Posted: 06 Jan 2022 10:28 PM PST I like to drink a somewhat niche (at least in the USA) type of tea called fu cha (aka fu zhuan or fu brick tea). This is a type of fermented tea made from real tea (camellia sinensis) in which a particular type of mold growth is induced and presents as golden spores known as golden flowers/"jin hua". After drinking a somewhat large amount of fu cha and feeling some sensations I've not noticed from other teas, I noticed that they felt somewhat related to the sensations I get when using cannabis. Now I recognize the effects of caffeine, but I am a bit skeptical of some of the less understood psychoactive effects which can be ascribed to tea, like 'tea drunkenness' and cha qi. But the feelings I had from this were different and too significant to ignore. Don't get me wrong, this was maybe 20% - 30% of the intensity of being high from weed (at least for me). Nonetheless, the sensations were very similar but of milder degree. So I wanted to see if there was something to this idea, and I did some searching around. As is pretty well known, the golden flowers (jin hua) found in most fu cha are actually the mold Eurotium Cristatum. Doing a bit of digging, I found some research that explains that this mold has certain metabolites which exhibit some sought after immunoregulation properties. And moreover, these metabolites' structures can act like another chemical that has a profile of activity "which is similar to, though less potent than, A9-THC... and is capable of mimicking the psychoactive effects thereof." To a non-chemist like me, this sounds like it's possible that this mold could produce psychoactive effects at some threshold (likely varying person to person) which are similar to TCH. However, I have no meaningful experience in biochemistry or organic chemistry, so I am not sure if I am interpreting those research articles properly. But I think I am. Can someone with a better understanding double check my work? TLDR: Does the research I linked above suggest that Eurotium Cristatum ingestion can produce THC-like psychoactive effects? (Edit: And to anyone worried that I'm asking this in hopes of abusing or distributing this as a substitute for cannabis, I live in Oregon, USA so such activities would be neither time efficient nor cost effective.) submitted by /u/Handyandy58 [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]

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?

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?

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]

When sliding a pipe into another pipe that’s a tight fit, why do we rotate the two? Posted: 05 Jan 2022 04:58 PM PST Like the title says, when sliding a tightly fit pipe into another one, why do we often rotate them to push in further? Why is it often easier to do so rather than to just push straight in? I was speculating that this might have something to do with static/kinetic friction, and that by rotating the pipes that overcomes the force of static friction and makes it slightly easier to push in further? Although I'm asking to see if anyone knows the real reason. Thanks! submitted by /u/Mr_Magic396 [link] [comments]

This may be a dumb question, but would it be possible to change what “type” of cell a cell is? Posted: 05 Jan 2022 07:50 AM PST So I'm currently taking highschool biology, and we're covering cells. The notes mentioned that cells such as blood cells, muscle cells, and nerve cells have the same DNA, they just have different genes activated by chemical signals. Assuming that this is correct, could purposefully giving the cells a certain chemical signal to make them into a different cell work? As an example of what I mean, perhaps sending chemical signals to a stem cell to create new nerve cells to repair nervous system damage. And if it is possible, why aren't we currently doing it? submitted by /u/AceBalistic [link] [comments]

What is the environmental impact of lithium mining? Posted: 05 Jan 2022 09:33 AM PST Lithium ion and lithium polymer are the most common batteries used today in EVs. With the increase in EV production, how does lithium mining's carbon footprint and overall environmental impact compare to traditional petroleum based cars? submitted by /u/cradle_of_humanity [link] [comments]

How much slower is the growth rate of tendons and ligaments (as well as other things im not aware of) compared to the growth of muscles? Posted: 05 Jan 2022 10:18 AM PST Title. I always hear how you should pace your trainings in the gym because tendons take a long time to adapt to increased workloads and etc. What ive never seen (after some quick googling) however are percentages and numbers for this. Does a tendon (and ligaments, cartilage, etc.) grow (or strengthen if those two are different) at 1/10th of the rate of a muscle? submitted by /u/noobiestnewbie [link] [comments]

How do the James Webb Space Telescope cooling systems actually dissipate heat? Posted: 05 Jan 2022 10:25 AM PST I've read many articles about the cooling systems aboard the JWST; I understand the engineering of both the passive and active cooling systems, but I don't quite understand how heat is actually lost from the telescope. On Earth, as far as I know, you typically remove heat from something by transferring heat to other matter, but there is not a significant amount of matter in space for the telescope to dispense its heat into. submitted by /u/Glandiun_ [link] [comments]

Many emojis have taken on their own meanings from memes (e.g. ��), often entirely unrelated to the picture (��️, ��, �� etc). When reading ancient languages, how do we know their pictographs didn't also have completely unrelated meanings that came from e.g. cultural memes of the time? Posted: 04 Jan 2022 05:57 AM PST For example if we were to keep seeing a picture of an animal, how would we know they mean that animal, instead of perhaps that meaning something completely different due to a cultural meme at the time. It could instead be related to virtually anything, just as many of our emojis have already taken on different meanings after only several years. Some of our emojis have a double meaning that you can kind of make out from the picture itself, such as 🍆 and 🍑. While others such as 🅱️, 🅿️, 💯, 🗿, etc have close to zero relevance. And similarly some of our double meanings last a long time, while others like 🚱 (explanation) suddenly take on another meaning but only for a very short period of time. If this happened in historic languages how would we detect it if they made a character a meme for a relatively short period? submitted by /u/Lost4468 [link] [comments]

Do polyphyodonts (animals with continuous replacement of teeth) have tooth sensitivity and nerve endings like humans do? In particular, mammal polyphyodonts. Posted: 05 Jan 2022 09:12 AM PST I have not been able to find a lot of information on this topic, granted I have a limited understanding of teeth. I was able to find that shark teeth do not have real roots and are not connected to the gums, so I assume they do not have nerves; but it seems that crocodiles may? Regardless, I am most interested if manatees grow properly connected teeth, as well as elephants and kangaroos. I also read that elephants have precisely 6 generations of teeth (?), so maybe all 6 sets are present and connected from birth the same way 2 sets are present in human children... but manatees seem to have infinite sets, so what then> submitted by /u/altiarblade [link] [comments]

Why does dampening my gloves make it touchscreen friendly? Posted: 05 Jan 2022 05:51 AM PST I have wool gloves, and it's index finger and thumb are touchscreen/touchpad friendly, but not other fingers.

Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 05 Jan 2022 07:00 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists.

How does terrestrial Co2 uptake work? Posted: 05 Jan 2022 09:23 AM PST Good morning, ​ I am researching the global carbon cycle and have a decent understanding of it, especially the ocean. However, I am a little bit confused about terrestrial/forest uptake https://upload.wikimedia.org/wikipedia/commons/d/d5/Carbon_cycle.jpg In the above image, I understand that the oceans sequester approx. 2Gt of carbon via mixing with the deep ocean. However it shows the net terrestrial intake as 3Gt of carbon. From what I understand, trees are just a "storage" of carbon and only uptake when they are young and are basically neutral when they mature, then when they die or a forest fire occurs they release all of their carbon and the only way a forest is a permanent sink of Co2 is if the forest is "managed" and the Co2 is trapped in wood products for the life of the product. ​ Based on this, assuming no major wildfires, pine beetle infestations, etc. is the 3Gt of Co2 that terrestrial areas uptake a reliable number annually? Or will there be a point in ~1000 years where there is no additional space for trees to be planted, most trees will mature/die, and that 3Gt of sequestration will actually be a net source of Co2 (if that makes sense lol) ​ thank you for any expertise! submitted by /u/Jumpy-South-1337 [link] [comments]

Does the static aging of an enzyme have an affect on its function? Posted: 05 Jan 2022 03:11 PM PST I understand that there are factors which affect the productivity of an enzyme such as: temperature, time exposed, cofactors etc. But does say leaving an enzyme out for X amount of time affect its overall function after that amount of time. For example if I had let the pineapple enzyme bromelain out for a week or a month, would it still function (or function less) after such amount of time? submitted by /u/Cube_11 [link] [comments]

Is there a relationship between elevational change, and the theoretical “equivalent” change in latitude? (temperature-wise) Posted: 05 Jan 2022 07:21 AM PST For example, let's say you're on the equator and go up 3000m in elevation. It's probably going to be quite a colder, even though you're in the same spot latitudinally. Now imagine you're on the equator again, and want to experience that same temperature, but this time by LATITUDINAL changes. Could you deduce how exactly far north/south to go? (If you assume all landscape features are the same, no change in elevation, no wind, etc) Bit of a theoretical question but as someone who recently was freezing in a relatively low-latitude place, I was really intrigued by this. Thanks for any clarity you can provide! submitted by /u/opteryx5 [link] [comments]
