| 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:

| 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? [link] [comments] |
| 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? [link] [comments] |

| 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? [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 [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. [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). [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. [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. [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!!

| 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! [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? [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? [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. [link] [comments] |
