AskScience AMA Series: We're Experts Studying COVID-19 In Deer and Other Wildlife. AUA! Posted: 17 Mar 2022 04:00 AM PDT In the past two years, dozens of animal species have been found to be infected with the SARS-CoV-2 virus. Of these, only two types of animals were found to be infected in the wild: mink and white-tailed deer. These findings have serious implications for managing (and ultimately ending) the COVID-19 pandemic. Join us today at 2 PM ET for a discussion, organized by the American Society for Microbiology (ASM), about our work to identify, diagnose and treat COVID-19 infections in wildlife. We'll discuss your questions about animal disease reservoirs, the potential for additional SARS-CoV-2 variants, and what our research (and the work of others) tells us about the role of wildlife in the COVID-19 pandemic, as well as future pandemics. We are laboratory researchers, veterinarians, and evolutionary biologists. Ask us anything! With us today are: Dr. Angela Bosco-Lauth, Ph.D., D.V.M. (u/VirologyVet)- Assistant Professor, Biomedical Sciences, Colorado State University Dr. Andrew S. Bowman, M.S., D.V.M., Ph.D., Diplomate ACVPM (u/Buckikid)- Associate Professor, Department of Veterinary Preventive Medicine, The Ohio State University Dr. Martha I. Nelson, Ph.D. (u/MI_Nelson)- Staff Scientist, National Center for Biotechnology Information, National Institutes of Health Links: Deer, mink and hyenas have caught COVID-19 – animal virologists explain how to find the coronavirus in animals and why humans need to worry (The Conversation) SARS-CoV-2 infection in free-ranging white-tailed deer (Nature) "This Week in Virology" podcast How serious is the presence of the Covid virus in deer for humans?

Why does the moon appear white while the sun appears yellow? Posted: 17 Mar 2022 06:08 AM PDT If I understand correctly, even thought the sun emits white lights it appears yellow because some of the blue light gets scattered in the atmosphere, leaving the sun with a yellowish tint. My question then would be why does that not happen to the light from the moon at night? submitted by /u/ymitzna [link] [comments]

If there is Electromagnetic radiation (light) and Gravitational radiation (gravity waves), is there Strong 'radiation' and Weak 'radiation?' Posted: 17 Mar 2022 07:48 AM PDT Gravity and Electromagnetism have a type of 'radiation' associated with them, but is this true for Weak Interaction and Strong Interaction being the other 2 of the 4 Fundamental forces? submitted by /u/BlockOfDiamond [link] [comments]

DNA has been compared to a set of blueprints that tells your cell to produce (or how to produce?) 'x' hormone/enzyme/etc that will have 'x' knock-on effect on the body... but what signal is sent to tell your cell to use that blueprint to produce 'x' in the first place?

How is HIV so effective at evading the immune system, despite it only having ~9,000 base pairs and 9 genes in its genome? Posted: 17 Mar 2022 11:17 AM PDT This seems pretty crazy to me. How can a virus be so effective with such little data? submitted by /u/Lost4468 [link] [comments]

Can massless light generate a gravitational field? Would parallel light rays eventually fall into each other due to gravity? Posted: 17 Mar 2022 09:47 AM PDT submitted by /u/BlockOfDiamond [link] [comments]

What does the lower limit of a bead in size chromatography mean? Posted: 17 Mar 2022 09:40 AM PDT I don't understand the fractional range of Gels in chromatography. For example, Sephadex G-50 has a range of 1500-30,000 Da. I understand that molecules above the limit of 30,000 Da will pass through more easily than those below it as they do not get stuck inside the pores of the beads. However, I do not understand why there is a minimum of 1500 because surely, anything below 30,000 will be slowed down by the pores? Does this mean that molecules below 1500 will pass through more easily? Thanks submitted by /u/Cheese2face [link] [comments]

How does the light reflect an image of outside onto my bedroom wall? Posted: 17 Mar 2022 01:46 AM PDT Weird experience this morning when I had my bedroom blinds down and noticed a bit of light coming in and when I looked closer it was an image of the outside being projected onto the wall. I even seen a car go by at one point. Sorry if this is a bad explanation. Also my blinds are a similar material to a projector screen is that makes a different lol. submitted by /u/lmcguire77 [link] [comments]

What is pounds-force divided by gravity? Posted: 17 Mar 2022 12:13 PM PDT For no reason at all, I decided to divide 145 pounds by 9.8 m/s^2, I'm left with 14.8. But 14.8 what? I was just messing around with units and am wondering if my question even makes sense or am I just making up stuff? I know why newtons are divided by gravity (to get kg in mass). submitted by /u/mysteryofthefieryeye [link] [comments]

Why do we season clay pots before their first use? Posted: 17 Mar 2022 09:53 AM PDT Interested in the science behind why we do this. I know clay is porous, but what does soaking and coating in oil have to do with it. submitted by /u/mattfisch [link] [comments]

What is the composition of the extraction fluid of a COVID-19 lateral flow test? Posted: 17 Mar 2022 01:08 PM PDT I would appreciate if you support your answer with a reference. submitted by /u/220-240volts [link] [comments]

Are the enzymes that metabolize drugs only found in the liver? Posted: 17 Mar 2022 06:41 AM PDT Hi! Probably a pretty basic question but I couldn't find the answer on Google. I'm wondering if the enzymes that your body uses to metabolize / break down medicines and drugs (e.g., CYP450) are found anywhere except the liver (e.g., in stomach acid, blood, etc.). Thanks!! submitted by /u/Fabulous_Street1441 [link] [comments]

How does our native language influence the way we create gibberish or imitate another language? Posted: 17 Mar 2022 02:49 AM PDT I was watching this video and I noticed how (obviously) when japanese people imitate English it still sounds like a made up asian language. I assume it has to do with the way the part of the brain that controls language is "programmed" to recognize and replicate familiar patterns, so a japanese will unconsciously filter English patterns through their native language and replicate it using familiar patterns (like syllables and sounds that are more common in Japanese), and the same would happen to me (Italian native speaker) if I had to imitate Japanese. I don't know anything about language or neuroscience, but I'm really curious to read some study or article about this topic. It probably overlaps with a lot of studies about the influence of our native language on learning a new one. In general, I'd like to read some books about the neurological aspect of language. I don't have any scientific background and I'm probably not capable of understanding more complex books, but I definitely prefer one that goes a little deeper than surface level even if I have to look something up from time to time. Thanks to everyone for you time! submitted by /u/pieceofcrazy [link] [comments]

Do nucleotides make base pairs when in a solution? Posted: 17 Mar 2022 05:57 AM PDT So, we know that complementary nucleotide sequences form base pairs, but what happens in the nucleus of cells, where there are a whole lot of individual nucleotides, not arranged into any chain? would you find most Cytosines and guanines together? Or is the hydrogen weak enough that it wouldn't matter at the molecule level? submitted by /u/Foreliah [link] [comments]

Question for chemists : how much energy could a osmosis battery store? Posted: 17 Mar 2022 02:11 AM PDT By osmosis battery I mean a system that stores energy in the osmotic pressure across a membrane, using just table salt and water. Like a giant piston where the increase in volume of the saline water is used to perform work, and energy can be stored by pushing it back. Pure water [ salt saturated water || working fluid] = Im not a chemist but I saw some paper about how the gradient between sea water and fresh water could be used to harvest .81kwh per m3 so it got me thinking about how maybe a giant version could be a cheaper and more sustainable alternative to giant short lived lithium batteries. depends how much it can store tho. Any thoughts? submitted by /u/hyperchromatica [link] [comments]

Is your voice a physiological or learned trait? Posted: 16 Mar 2022 09:49 PM PDT By voice, I mean the distinct timbre and tonal qualities. Does our voice come from actual physiology or is it a cognitive thing that we learn from mimicking others? Is it possibly inherited/genetic? Like, my mother and I have such a similar voice that people can't tell us apart on the phone. I know a girl and her sister (3 years apart) who both have a very distinct voice that sounds the same. I know identical twins who sound identical as well. submitted by /u/Tig_Ole_Bitties [link] [comments]

AskScience AMA Series: I'm Patrick Long, M.D. and I am a geneticist with a specific interest in the adult genetics field. I just started an adult genetics clinic, SequenceMD, to address the needs of this widely underserved population. AMA! Posted: 16 Mar 2022 04:00 AM PDT Hi Reddit! SequenceMD team here: we are Dr. Patrick Long and genetic counselor, Alisha. We're here to answer any questions you may have about medical genetics or... anything! We'll start by answering our own question: why adult genetics? Genetic testing is a routine part of the diagnostic workup for many childhood onset disorders including cerebral palsy, developmental delay, movement disorders, etc. Your genes don't change when you turn 18, but it's still not standard of care to test adults living with these disorders. In some cases, genetic testing can reveal treatment options, management guidelines, or preventative care, that is very much relevant to adults. Most geneticists in the United States are pediatric focused. Adults who are able to see a geneticist may face long wait lists or be denied testing. We believe that genetic testing should be an accessible choice for those who are interested. We'll be on at 10AM MDT (12 PM EDT, 16 UT), AUA!

Is Africa's large number of endemic diseases related to the idea that humans most likely evolved there? Posted: 16 Mar 2022 11:13 AM PDT Do places with similar ecological conditions like in the south american rainforests also have as many endemic diseases? submitted by /u/Deathglass [link] [comments]

How do migratory birds who fly huge distances keep track of all the different predators and edible/non-edible foods they might encounter on their journeys? Posted: 16 Mar 2022 11:14 AM PDT Some birds fly thousands of miles on their migrations and it seems to me that these birds would need to keep track of lots of different types of food sources, as well as being aware of threats posed by different predators, and other dangers, along the way. Is it all just inherited memory or instinct? Or do the younger birds just copy the older birds and the cycle just keeps repeating? submitted by /u/PlanetOfTheAprons [link] [comments]

Why does the latest alignment image from the JWST have streaks in it? Posted: 16 Mar 2022 02:22 PM PDT https://www.nasa.gov/sites/default/files/thumbnails/image/telescope_alignment_evaluation_image_labeled.png Why does the central star have the 6 large streaks coming out of it? Doesn't that mean that there's aberrations in the optical system? submitted by /u/ilovethemonkeyface [link] [comments]

can cats recognize themselves in the mirror? Posted: 15 Mar 2022 09:23 PM PDT Or do they learn to tolerate the weird odorless cat? Anytime my cat sees another,she goes APE SHIT,same for dogs. she is TERRIFIED. Doesn't matter if it's thru a closed window or not. submitted by /u/Platinumsteam [link] [comments]

What did the dinosaurs/birds that survived the k-t extinction event look like? Posted: 16 Mar 2022 12:37 PM PDT I've always been curious what these animals looked like. I know many animals we would call birds today existed at the time, but did any of the more dinosaur-like birds survive? did any other small dinosaurs survive for a time? submitted by /u/eevee047 [link] [comments]

Are quark stars and strange stars real? Posted: 16 Mar 2022 05:23 PM PDT Their existence seems to be much less accepted than neutron stars or black holes, but why shouldn't they exist? As I understand it they are just denser states of matter, and if we think black holes and neutral neutron stars exist, then it would be very likely that some objects with a density in between exist too? submitted by /u/cowox93112 [link] [comments]

Did the asteroid that killed off the dinosaurs have a name? Posted: 15 Mar 2022 08:47 PM PDT Everyone knows that the asteroid that took out the dinosaurs landed in Yucatan Mexico, and the crater is called the chicxulub crater, but did the meteorite itself have an actual name? submitted by /u/OkSlice3886 [link] [comments]

Is genetic colorblindness due to a difference in the eyes or brain? Posted: 15 Mar 2022 05:42 PM PDT I've tried finding this out from Google to no avail. I know colorblindness can be acquired by either damage to the eyes or brain, but is genetic colorblindness due to differences in the eyes or brain? I know both are responsible for typical color perception. submitted by /u/Peachntangy [link] [comments]

Could a Chinese Water Dragon and Bearded Dragon produce viable offspring? Posted: 15 Mar 2022 06:44 PM PDT I know they aren't in the same genus, but they're both in the family agamidae. Just got curious about this submitted by /u/TankmanSpiral7567 [link] [comments]

Have wages kept up with inflation over the last 50 or so years? Posted: 15 Mar 2022 06:43 PM PDT I read often on social media, especially Reddit, that wages haven't kept up with inflation, but that seems contrary to the data at a cursory glance: https://www.pewresearch.org/fact-tank/2018/08/07/for-most-us-workers-real-wages-have-barely-budged-for-decades/ Workers in 1964 made ~$20/hr in 2018 dollars, and workers in 2018 made ~$22.50 per hour. Does this accurately represent reality or has the way inflation is calculated not properly capture changing economic circumstances? EG, you can now buy a small black and white tv for super cheap. That doesn't really do much to improve your quality of life if you are struggling, but a worker's earning power technically increased vs someone in the 60's. submitted by /u/CartoonistStrange399 [link] [comments]

Why is the Earth not tidally locked with the Sun? Posted: 14 Mar 2022 05:37 PM PDT The moon is tidally locked and always has one side facing Earth, so why doesn't the earth do the same with the Sun? Given enough time, will it? submitted by /u/feed2brdswitonescone [link] [comments]

Does your body become less "skilled" with rarely used autonomous functions in the same way as conscious skills? Posted: 15 Mar 2022 08:12 AM PDT It's pretty clear that if you don't use a physical skill regularly (say golf swings, hand-eye coordination, the perfect goal kick, etc.) it'll degrade over time. Does something similar apply to autonomous functions like, say, throwing up, conscious urination (as opposed to a catheter), ocular response (for people who are blind), etc.? submitted by /u/MitchellFanAccount [link] [comments]

How do neutron star mergers populate the universe with heavier elements? Posted: 15 Mar 2022 08:38 AM PDT There's something remarkable I learned from PBS Space Time recently - there's an extra step in our cosmic history! Initially the pathway to the modern galaxy was: Hydrogen / Helium production from big bang Coalescence to primordial stars In these stars, fusion of elements up to Iron, and production of heavier elements from the resulting supernova Coalescence of these elements to create the contemporary stars and galactic matter The discovery (not sure how recent), is that production of heavier elements from a supernova can't be responsible for the observed abundance of above-iron elements. Something about the rapid neutron capture process (r-process) not occurring at a high enough rate to fuse these heavier elements. The candidate now for r-process are neutron star mergers. Now my question: how can this be possible if neutron star mergers always or almost always create black holes as dictated by their solar masses? The typical solar mass range for a neutron star is 1.4 to 3.2, and the typical lower limit solar mass range for black holes is 1.5 to 3.0. I am thinking that the merger of any neutron stars would create a black hole, and therefore it doesn't matter how fruitful your r-process is, all those heavier elements are now sequestered in a black hole. Can someone help explain how this matter could be ejected from such mergers? Thank you! submitted by /u/ChaoticLlama [link] [comments]

How can we create agonists that only bind to one receptor subtype? Posted: 15 Mar 2022 07:45 AM PDT For example, we can synthesize molecules that only bind to one adrenergic receptor subtype. Since it has to be similar in shape to epi/norepi, how does this specificity occur? Do these specific agonists stimulate the other adrenergic receptors to some degree? submitted by /u/Vitaminx219er [link] [comments]

What are the differences between serotonin agonists/antagonist, short term vs long term? Posted: 15 Mar 2022 06:35 AM PDT Am I correct in thinking serotonin agonists raise serotonin? And that antagonists reduce it? But in terms of sensitivity to serotonin, agonists decrease and antagonist increase? What are the key differences between the two and how do they affect someone short term vs long term. I'm very curious on the subject. I took tryptophan which is a precursor to serotonin and didn't feel too great. Started getting brain zaps. I then a few days later took tyrosine to boost dopamine and reduce serotonin and this gave me a huge migrain. Both times had high levels of anxiety, and anxiety is something I've dealt with for a while. I've never taken medicine but have done psychadelics in the past. I stopped when I realised I was getting brain zaps a couple of days after a psychedelic trip. It's got me very curious about my own brain chemistry and why I'm getting these effects. It's a complex issue but hoping someone could share the light on something? submitted by /u/MKS18 [link] [comments]

What is the most complex endosymbiosis event (e.g., dinoflagellates)?

Posted: 14 Mar 2022 08:47 PM PDT I mean, Venus had such a think atmosphere, thicker than Earths & is so hot around the entire thing, yet is a similar size. It just baffles me that Mars potentially lost its atmosphere because no magnetic field, yet Venus never did. Finally, does Earth actually need a magnetic field to keep its atmosphere protected from solar winds? Or are there just different mechanisms to protect an atmosphere & Earth's happens to be a magnetic field? submitted by /u/acetryder [link] [comments]

Posted: 14 Mar 2022 07:28 PM PDT There are lots of RAT kits out there recently. Where I live (Hong Kong), the government has a daily change of mind whether we'll be mandatorily tested (3 times in a roll) and how it is going to be arranged. Anyhow, it gets more people nervous and many buy these kits as contingency. After an initial lack of supplies, it is quite abundant today. Here is a sample list: https://www.covidrat.info/rat/item-search (credit to a redditor who wrote the website, pulling data from various location). What I notice is that these kits sort of center around 2 price levels: around USD2.5-5, and around 10-15. Those that are made in China are cheaper. Those that were from Germany are more expensive. But other than that, I can't find significant differences in terms of accuracy etc. Is that the only difference? Are there different technologies (to create the kit) that create the huge price gap?

why is bone growth (epiphyseal plate) not possible after plates close ? Posted: 14 Mar 2022 10:23 PM PDT Why is bone growth impossible, for example if growth plates have closed. Knowing how growth plates work, why would applying enough pressure through whatever means you'd like (let's use a weight for example) allowing to create space within the bone (growth plate) allowing for more bone to grow. Obviously, you have to apply an exceptional amount of pressure to the epiphyseal to allow the bones to separate, causing growth. Disclaimer: i'm aware of the basic reasoning behind it, but feel like there is more of a reasoning behind it submitted by /u/Long_Rip_1987 [link] [comments]

Is it possible for intestines to "narrow" in the course of life? Posted: 14 Mar 2022 07:39 PM PDT Im curious if there are mchanisms that would cause the narrowing of intestines. I dont mean the length. I suppose maybe the correct word is the circumfrence....the interior space inside the tubing of the instestines. A campbells soup can thinning to a small pill bottle? Is it possible for only a portion of the instestines to do this? If this is possible...what might be such a cause? submitted by /u/SequinSaturn [link] [comments]

Are there any non-steroid testosterone precursors? Posted: 14 Mar 2022 10:48 AM PDT Are there any precursors to testosterone that do NOT have the side effects of anabolic steroids and are NOT considered steroids? Is there something before testosterone in the transduction pathway that if someone were to take they would boost their T levels? submitted by /u/Ridiculous_Cheese19 [link] [comments]
