What's the dry, papery layer inside a peanut shell and what's it for? Posted: 26 Nov 2021 08:34 AM PST It's not connected to anything but is (static?) clinging to the "nut"/legume itself, it must have dried off of something? submitted by /u/jeremyfrankly [link] [comments]

Can someone please explain the name of the newest covid variant B.1.1.529 ? Posted: 26 Nov 2021 12:55 AM PST I know it is based on PANGO system: https://en.wikipedia.org/wiki/Phylogenetic_Assignment_of_Named_Global_Outbreak_Lineages Can you explain how does the PANGO system work? Does it always start with a letter? What does the letter means? What does the dot means? What does the number mean? I know the complete explanation is here: https://www.pango.network/the-pango-nomenclature-system/statement-of-nomenclature-rules/ But it is too difficult for me to understand. submitted by /u/BeatriceBernardo [link] [comments]

Historically speaking, how was breathing/respiration explained? Posted: 26 Nov 2021 07:31 AM PST People must have been aware that you need to breathe in order to stay alive. How did they try to explain this before the modern explanation was established? submitted by /u/Schmiergeld [link] [comments]

What holds the debris together of an object that has been torn apart by tidal forces around a larger body after crossing it's Roche limit? Or how large can those remnants be? Posted: 26 Nov 2021 02:57 AM PST Hi, hope you are all well. When a planet, moon, etc. crosses the Roche limit of a larger, more massive body, and is torn apart, what sets the limit on how small those fragments can be, and is there a calculable lower limit on their size? Thanks! submitted by /u/Ixthos [link] [comments]

Can a paralyzed body part still convulse during a seizure? Like, if someone is paralyzed from the waist down, will their legs still convulse during a seizure? Posted: 25 Nov 2021 09:00 PM PST I honestly don't know how this question came to my mind. submitted by /u/Lumini_317 [link] [comments]

Do inflammatory markers vary over time? Posted: 26 Nov 2021 05:26 AM PST I work on a ward with elderly patients and notice that not all have clearly raised inflammatory markers with infection, some of them have random fluctuations day by day. What could be causing this ? A one day lasting cause? (often its ptients with various comorbidities)? submitted by /u/nickoskal024 [link] [comments]

Can an object be accelerated to (almost) the speed of light arbitrarily fast? Posted: 25 Nov 2021 07:32 PM PST Or is there a physical limit to acceleration as well as speed? Thank you. submitted by /u/icecap1 [link] [comments]

how do we know what killed the dinosaurs? Posted: 25 Nov 2021 11:12 PM PST (which flair?) to elaborate my question: is there proof of it being a asteroid that wiped the dinosaurs or is it just assumptions made since its the most logical conclusion? edit:thanks for the answers submitted by /u/fnafproo [link] [comments]

Does tiny almost not noticeable eartquakes happend regulary? Posted: 26 Nov 2021 07:27 AM PST I've noticed something strange. sometimes i feel like what i would describe as an extremely gentle earthquake feeling. Like something is very gently shaking everything from side to side. Any idea what this could be? ive ruled out all kinds of stuff like trucks etc. could it be actual eartquake but soft? submitted by /u/PythonNoob-pip [link] [comments]

Covid attacks cells in the olfactory epithelium to cause loss of taste and smell, can't these cells eventually regenerate from basal cells in the epithelium, given enough time? Posted: 25 Nov 2021 07:58 PM PST one would think that unless covid destroyed every single basal cell, these cells would eventually multiple and replace damaged cells in the olfactory epithelium, thus restoring taste and smell. depending on the damage, it could take a very long time, but in theory wouldn't these senses have to return? submitted by /u/still_alive11 [link] [comments]

Can electroless plating be "masked" to not deposit? Posted: 25 Nov 2021 10:55 PM PST In a copper electroless plating process using Formalin as the reducing agent, any part of the substrate treated with a borohydride salt solution gets plated in copper. The whole substrate needs to be dipped in the borohydride salt, but some sections of the substrate do not need to be plated. Is there anything I can apply to the substrate (or mix into a resin) to mask sections from being plated? ​ My first thought is a very thin coat of oil, however I think that might come off and contaminate the plating and borohydride baths. ​ Thank you! submitted by /u/Wyattwic [link] [comments]

Do things get cold faster in colder environments? Posted: 25 Nov 2021 12:39 PM PST Title basically. But for example if a cube was in a -70 F room and the same cube was in a -30 F room which one would reach -20 F first if they both started at same higher temperature. submitted by /u/Kraken78 [link] [comments]

Does bronze or copper release toxic fumes when exposures to fire? Posted: 25 Nov 2021 09:56 PM PST I'm working on a Christmas gift and want to be sure I don't harm anyone that uses it.

Since insulin regulates the production of ketones, what prevents Ketoacidosis when a Type 1 Diabetic attempts a ketogenic diet? Posted: 25 Nov 2021 05:07 AM PST When a Type 1 Diabetic attempts to follow an extremely low carb diet they would have to take close to no insulin or else they would risk facing repeated low blood sugar levels which then would force them to eat carbohydrates to raise, making the diet no longer low carb. When insulin levels are cut too far down from a low carb diet, why doesn't ketoacidosis occur? Do Type 1 Diabetics on keto produce more ketones because of this? And if so, does that mean that they can shred excess fat at a more effective rate than someone without the disease? submitted by /u/T1Bam [link] [comments]

How does Swine Flu Work? Posted: 25 Nov 2021 09:43 AM PST It's thought that all Influenza originate from Birds, so why is that Swine Flu, being a strain of Influenza, primarily targets Pigs, and not Birds which should be their primary host they are adapted to? Is Swine Flu now primarily adapted to Pigs, having changed it primary host when splitting off into a new strain? How could that be possible considering it's fairly recent emergence? submitted by /u/KarmaWhoreCam [link] [comments]

What happens to the suprarenal glands after a kidney removal? Posted: 24 Nov 2021 10:35 PM PST I'm studying biology for med school admission and I'm learning about glands.

How does spacecraft fairing size affect the rocket handling? Posted: 24 Nov 2021 09:47 AM PST Today's SpaceX DART launch featured a fairing that was larger in diameter than the main rocket body. Instinctively, this looks unstable, but obviously it is not (or at least, not in any way that can't be handled). Does the added drag, aerodynamic effects, or mass outside the width of the main rocket body cause much trouble? submitted by /u/Matir [link] [comments]

Is there a correlation between "Adrenal Fatigue" and Hypocortisolism (or Blunted Cortisol Response)? Posted: 24 Nov 2021 01:34 PM PST "Adrenal Fatigue" is a syndrome talked about in alternative medicine that is not accepted as a legitimate diagnosis in conventional medicine. On the other hand, mainstream science is beginning to discuss Hypocortisolism - I don't mean Addison's Disease - as a possible mechanism involved in the pathology of some condition that result from chronic or extreme stress such as PTSD, as well as other conditions such as Chronic Fatigue Syndrome and Fibromyalgia. It is speculated this is as a result of Hypothalamic Pituitary Axis dysregulation. When I read up on "retro" diagnoses such as Neurasthenia and Shell Shock, I start wondering if they were the same conditions with different names and all had this particular "blunted cortisol response to stress" phenomenon in common. As a layman with no background in medicine, when I read up on "Adrenal Fatigue" and Hypocortisolism, they sound very similar. And if it has been now recognized that some form of pseudo "Hypocortisolism" that isn't extreme enough to constitute as Addison's Disease may be behind a lot of chronic functional or mental conditions, why isn't more research being done to correct this form of Hypocortisolism? All I find on this subject is antidepressants can modulate the Hypothalamic Pituitary Axis to correct Hypercortisolism in depression, but nothing on how to fix a blunted cortisol response to stress. Many patients with PTSD are put on antidepressants, which to me sounds like reduces cortisol. Nicotine increases cortisol. Is it possible many people with mental disorders use tobacco to up regulate their cortisol response to stress? submitted by /u/Prefect1969 [link] [comments]

what’s the difference between rh-null and rh-negative? Posted: 24 Nov 2021 08:21 AM PST i've fallen down a rabbit hole of blood types and stuff lately. i know rh-null is extremely rare. around 50 people in the world have it if i'm correct. if rh- neg means it doesn't contain the rh antigen, then isn't that just rh-null submitted by /u/useless_orange_v [link] [comments]

What happens when a person takes antibiotics? Posted: 24 Nov 2021 08:06 AM PST Let's use a sinus infection as an example bacterial infection, as there are a lot of secondary symptoms, like sinus pressure, inflammation, fatigue, lack of appetite, etc, that are present secondary to the bacteria itself - and sinus infections are well known to the general public. Azithromycin dosage starts with 500 mg, followed by another 250 mg every 24 hours. After that first dose, it peaks in the blood at 2 hours in, and the patient can start feeling better after 3-4 hours (although azithromycin stays in the blood stream longer, up to 10 days even though the dosing regiment ends after 5 days). By what mechanism do antibiotics work this quickly? Are the antibiotics literally killing bacteria in that short time? Or is there something more going on, giving the immune system a break to stop producing t-cells or reducing inflammation, etc? Essentially, my question is why do antibiotics work so quickly (with azithromycin as an example, but really any fast working antibiotic is applicable) and how does the antibiotic have such a quick and marked effect on symptoms? submitted by /u/bebe_bird [link] [comments]

How do cells recognize each other? Posted: 24 Nov 2021 08:51 AM PST In Immune by Philipp Dettmer, he describes your immune system as differentiating between your body and antigens with the analogy of checking if puzzle pieces fit together. In a bit more depth, what is happening when cells check to see if these protein "puzzle pieces" fit together? submitted by /u/jenovaside [link] [comments]

Do worms (I was thinking earthworms, but nematodes of any kind will work) have a distinct top and bottom? Posted: 23 Nov 2021 08:12 PM PST Like, is there a part of the worm that it would prefer to be touching the ground? Do they get disoriented if the wrong side of them is up? submitted by /u/Toorelad [link] [comments]

Does sound waves become muddled with noise if the medium it travels through is very hot? Posted: 24 Nov 2021 02:36 AM PST My rudimentary understanding of temperature has always been that particles "jiggle in place" more "violently" when their temperature increases. So, I wondered whether an increase in temperature in the medium a sound travels through, has an effect on the noise that medium introduces to a given acoustic signal. I imagine it would have no noticeable effect since sound is a more macro phenomenon, but it never hurts to ask :) submitted by /u/RazomOmega [link] [comments]

AskScience AMA Series: We're journalists who used genomic sequencing data to reveal how a dangerous strain of salmonella spread through America's chicken industry and still makes people sick. We also made a tool to let people check where their chicken and turkey came from. Happy Thanksgiving, AUA! Posted: 24 Nov 2021 04:01 AM PST We're ProPublica reporters Bernice Yeung, Michael Grabell and ProPublica data reporter Irena Hwang. Bernice and Michael have spent years reporting on the U.S. meatpacking industry, while Irena used her background in bioinformatics to track salmonella infantis, a dangerous strain that's sickened tens of thousands of people, including some who died, in the past few years. Other countries have all but eliminated salmonella in poultry, but in America, infantis has been allowed to spread and continues to make people sick. The USDA knows about it. The meat industry knows about it. But the public? Not so much. Most people know that cooking poultry kills salmonella, but many studies found that cooks routinely cross-contaminate their kitchen surfaces after handling raw meats, which means that bacteria like salmonella are still a risk. In addition to publishing a huge exposé on the outbreak, we also made a database that lets anyone look up where their chicken or turkey came from, as well as how often dangerous salmonella was found by USDA inspectors. We call it Chicken Checker. In spite of the name, Chicken Checker also lets you look up turkey. Happy Thanksgiving. Keep up w/ ProPublica on Twitter or via Email, and we'll see you all starting around 11 am ET (16 UT), AUA! (P.S. If you look up your chicken on Chicken Checker, be sure to fill out the information at the bottom of the page - it'll help us track supply chains and do more journalism that helps consumers).

Monoclonal Antibodies and COVID vaccine? Posted: 24 Nov 2021 12:29 AM PST Question for those of you that understand immunology. We know that the CDC says to wait 90 days between the monoclonal antibody infusion for COVID 19 and getting vaccinated (first dose). Can anyone give insight into why? What is the science behind needing to wait? Would it cause serious adverse/side effects or would the antibodies from the infusion and the antibodies from the vaccine go to war with each other per se? Not looking to get into a vaccinated vs unvaccinated discussion. Just curious about the science of it. submitted by /u/Creamymoistmustard [link] [comments]

How much lava is there on earth? Posted: 23 Nov 2021 10:03 PM PST My son's actual question (the relevance of which we may ignore for now) was if there was more water or more lava on earth. I have read estimates on the amount of water, but it seems to be an interesting, uncommon question how much lava there is on (in) our planet. (I guess this would be a question for Randall Munroe..) PS: Hope I got the right flair. Please tell me otherwise. submitted by /u/matty_lean [link] [comments]

What exactly does the Strong Force affect? Posted: 23 Nov 2021 05:05 PM PST I'm aware that protons and neutrons are made up of 3 quarks each. Each of them have a 'color' of the force that keeps the particle together. My understanding is that this balance is the strong force. However, there is also in physics a strong force that keeps all the protons and neutrons in the nucleus of an atom (other that gravity). I'm not finding any mention of color. Is it the same force? It seems weird that there would be additional strong force since affecting the protons and neutrons since they are internally color satisfied. submitted by /u/InvaderMixo [link] [comments]

What does ''chain mobility'' mean and why does a lower chain mobility make a polymer harder to hydrolyze ? Posted: 23 Nov 2021 01:34 PM PST I read that polymers like PET are hard to hydrolyze because of their high ratio of aromatic units, which reduces their chain mobility. Could anyone explain to me what chain mobility is exactly ? And why it has anything to do with hydrolysis of the polymer ? submitted by /u/BringBackDumbledore [link] [comments]

If you were to throw a baseball from the iss would it reach earth? Posted: 23 Nov 2021 08:36 PM PST Assume normal human arm strength.

Why am I getting the opposite color change for a complexometric titration using Eriochrome Black T? Posted: 23 Nov 2021 08:27 PM PST Hi all, I am trying to conduct a complexometric titration involving antacid, by trying to determine its magnesium concentration (which is in the form of Mg(OH)2 in my antacid) through EDTA. I've seen in a bunch of places online that the color change should go from red to blue when the indicator Eriochrome Black T is used, as a result of this equation: MgIn- + HEDTA3- <--> MgEDTA2- + HIn- Wine red Blue However when I add the indicator to my antacid, I get a moderate blue color, that gets darker as I titrate EDTA (0.25 mol) into it. I added drops of a pH 10 buffer solution to the analyte before titrating as well, as I think the titration needs to be at that pH to work. One reason I thought of is that the antacid I'm using has a lot of aluminum hydroxide in it, however I was under the assumption that EDTA does not typically form complexes with aluminum and that it shouldn't affect my titration. This is a report on the specific antacid I'm using by the way: https://www.medicines.org.uk/emc/product/5550/smpc — in my experiment I diluted it heavily, diluting around 156 ml to 1.25 liters. I tried using different amounts of the antacid, EDTA, pH 10 buffer solution, and indicator, and was not able to get the correct colors. I also read somewhere that heating it could help it? Though I tried that and did not see a difference. If there's anybody who could possibly help me with this, I would appreciate it greatly. Thank you so much submitted by /u/SlooBananas [link] [comments]

Is the naming scheme used for COVID-19 common in virology? Posted: 23 Nov 2021 10:18 PM PST From an article I read. In COVID-19, 'CO' stands for 'corona,' 'VI' for 'virus,' and 'D' for disease.

Can I "average out" water temperature by adding volumes at a specific temperature? Posted: 22 Nov 2021 10:23 PM PST Let's say I want my bath at a perfect temperature, but my water heater is busted. I have a jumbo cauldron at my fireplace, though, so I boil up 25 gallons of water, and mix it with my ice cold tap water, trying to get the temperature just right. Just to make the math easy, I have 25 gallons of boiling water at 100c, and I mix it with 25 gallons of 25 gallons of almost freezing water, call it 1c. Will that give me a nice 50 gallon bath at 50c? Or do I end up with some other temperature? submitted by /u/cessna120 [link] [comments]

Posted: 23 Nov 2021 08:27 AM PST Especially big rocks, how could they just be sitting out in places with no water, near no places with volcanic activity, and if large volcanic eruptions put them there wouldn't their be pieces of volcanic rock there too? submitted by /u/crediblewordbank [link] [comments]

Do the same tactics to reduce exposure to COVID (mask indoors, frequent handwashing) work for the flu and common cold in the same capacity? Posted: 23 Nov 2021 10:42 AM PST See also: suggestions for only gathering outdoors, 6-feet apart, etc. I *assume* they do, but perhaps the common cold/flu has their own weird methods of infection. submitted by /u/senordingleberry [link] [comments]

Why can't alpha-amylase (either salivary or pancreatic) break down disaccharides like Sucrose or Maltose? Posted: 23 Nov 2021 12:18 AM PST a-amylase is a glucosidase that hydrolyzes a1,-4 glyosidic bonds between monosaccharides. Maltose and Sucrose are also linked by a1,4 linkages but during digestion, they are hydrolyzed by brush border disaccharidases. Why is this so? Why can't a-amylase do the job? Thank you. submitted by /u/OcularSpite [link] [comments]

How do radios work? (and other devices controlled by radio waves) How is the sound information encoded onto the wave, and how does the home radio turn the light information put back in the speakers? Posted: 22 Nov 2021 03:11 PM PST I understand that radios (like what is in your car) need electrical power (from batteries/wall outlet/car) and get radio waves that are from transmitters. Radio waves are a kind of light wave. However, in my daily experience with light, information is not encoded onto the light wave other than color (and maybe amplitude.( This is another thing that is unclear to me. What is the amplitude of a light wave? Is it even meaningful to say "the amplitude of a light wave"?) How is the sound information encoded onto the wave, and how does the home radio turn the light information put back in the speakers? Thanks so much! submitted by /u/Completeepicness_1 [link] [comments]

Why emission peaks redshift when concentration increases? Posted: 22 Nov 2021 10:10 AM PST Can someone explains to me why is that? I was measuring fluorescein emission spectra at different concentrations ( 0.01mM , 0.02mM , 0.05mM) in a 10mL solution of distilled water and 0.5mL NaOH 0.1M. Thank you!!! submitted by /u/gpalo [link] [comments]

Can COVID-19 get transmitted through hair? Posted: 22 Nov 2021 09:04 PM PST I want to know how long the virus can live on the hair on our heads. It's been a great source of anxiety for me to the point where I'm cutting my long hair short. submitted by /u/seaofflames [link] [comments]
