| How do antivirals target only viral RNA and not host RNA? Posted: 07 May 2022 05:22 AM PDT Edit: I understand that many antivirals affect the viral polymerase, but I'm most interested in nucleoside analogs like molnupiravir… how do they affect only viral RNA and not host RNA? [link] [comments] |
| Why are so many of the worlds deepest caves in Georgia? Posted: 08 May 2022 01:59 AM PDT 7/45 of the worlds biggest caves are in Georgia, including the top 4. Why is this? What is so special about the geology of such a small country that in contains such deep caves? [link] [comments] |
| If allergies can come from repeated exposures, why are we not allergic to everything? Posted: 07 May 2022 07:52 AM PDT Correct any assumptions I may have made, but I have read about how allergies can come from repeated exposures to something. For example, I've read the story about how cockroach researchers eventually become allergic to them, and in turn have an allergy to instant coffee. How come we aren't allergic to things we experience everyday in our lives? I eat wheat almost everyday, will I eventually get to the point where I die if I walk past a bakery? Will all pet owners become allergic to their pets? Will youngsters all develop an allergy to AXE bodyspray? Will someone eventually become allergic to a medication that they take chronically?

| Is hyperphalangy/hyperdactyly a thing in humans, like it is for some dinosaurs? Posted: 07 May 2022 04:38 PM PDT I'm studying ichthyosaur fins for my university dissertation, and I'm looking at polyphalangy (defined as phalanges branching from digits) and hyperphalangy (additional phalanges added linearly onto digits) (see this image from Fedak and Hall, 2004 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1571266/figure/fig01/). Obviously there's polydactyly in humans, with extra fingers, but I was wondering if there's 'hyperdactyly', with more than 3 phalanges in a finger? I'd imagine that if both conditions occur in ancient organisms then they could also occur in humans? edit: terminology [link] [comments] |
| Where is the next largest mountain range being/going to be created? Posted: 07 May 2022 12:55 PM PDT Throughout random readings I've found that the Appalachians used to be larger than the Himalayas. Are there any new ranges currently forming and will any range formed ever be as large as the Appalachians considering tectonic plate movement is gradually slowing? [link] [comments] |

| Can someone explain how cancer spread into your lymph node? Posted: 08 May 2022 03:12 AM PDT I've read IMMUNE from Kurzgesagt, and now I'm watching Breaking Bad. So I want to know how cancer can spread into your lymph node. Thanks!! [link] [comments] |
| Can the most extreme weather for a region happen in the next 5 or 10 years rather than 50 -70 years? Posted: 07 May 2022 10:39 PM PDT Can a region anywhere on earth possibly experience the worst climate in the next 5 or 10 years rather than in 50-70 years in this century? Or will climate change make it certain that the worst is going to happen only after 50 or so years? [link] [comments] |
| Do all mammals experience nausea, and how can scientists determine this? Posted: 07 May 2022 05:59 PM PDT For example, dogs experience nausea and it is often indicated by drooling and excessive swallowing, and anti-emetic medications work for dogs. But outside of observed behaviors, do scientists have other ways of knowing whether nausea is something that all mammals experience? Could it be determined by studying mammalian brains?

| How does a drug's half life relate to the duration of its effects? Posted: 07 May 2022 08:29 PM PDT This is mostly regarding psychoactive substances, but it seems for most substances, the half-life is much longer than the duration you actually feel the drug's effects. Take ativan for example. It's half life seems to be around 12 hours, although apparently a better estimate is between 10 and 12 hours. Yet it does not seem to ease anxiety for nearly that long. Another example would be adderall. It's half life is over 12 hours, yet its effects last for around 6 hours. Even alcohol seems to be weird in this regard. It's half-life is 4-5 hours, but you're also able to process a drink in around an hour. If I had a drink and then waited an hour, I would blow a 0.0 BAC, but it would still be in my system? Can anyone clear this up for me? Is it that the drugs still have a psychoactive affect, but it is just no longer noticeable or what? [link] [comments] |
| Why are examples of viruses jumping between kingdoms so rare compared to zoonosis? Posted: 07 May 2022 07:44 AM PDT I know there are some examples of viruses jumping host kingdoms, but they seem relatively rare compared to how often they jump between host species. Of the examples we do have, many of them we don't have direct evidence for, the jump is inferred from evolutionary evidence because it happened too far in the past. Is the jump between kingdoms 'harder', and if so, why? [link] [comments] |

| Posted: 06 May 2022 05:15 AM PDT So, what I've heard is that lobsters keep growing throughout their life, getting bigger with each moult. I've also heard that the reason lobsters will die at a certain age is not because of internal processes, but because they are unable to effectively moult and die as a result. Firstly, is this correct? And if this is correct, is it therefore theoretically possible that a lobster could be aided in moulting, and we could just pass this lobster through generations as it just gets bigger and bigger? I severely doubt this is the case, but without having contrary information on lobster biology, I'm just going to have this at the back of my mind [link] [comments] |
| How does Phantom cameras shoot 1 million frames per second? Posted: 06 May 2022 02:24 PM PDT Can someone explain the technology behind it? How do photo sensors work and what allows it to refresh so quickly? Wouldn't the speed of electricity flow become a limiting factor at such high frame rates? [link] [comments] |
| Posted: 06 May 2022 05:43 PM PDT Optics, often old optics, can contain thorium because of the excellent refractive characteristics of thorium. The downside of using thorium is that it is radioactive and emits alpha particles while it decays. These high energy electrons do affect atoms in the glass lattice, inducing damaged spots due to exciting their electrons that will leave their normal positions and start moving through the glass lattice. These additions or removals of electrons can result in an F-spot, colour spot, that can absorb light. The energetic electrons passing through the network can collide with other electrons. The collision can cause the other bound electron to be ejected from its normal orbit and move through the lattice. Less strong collisions can cause thermal motion of the lattice, resulting in electron-deficient regions, holes. These holes can move through the lattice and are stopped near impurities or defects. The moving electrons can also be trapped near lattice impurities or defects, or recombine with holes. A way to ''clean'' the glass is to anneal it, so diffusion can take place to ''repair'' the damaged spots. However, on the internet people report that ultraviolet (UV) radiation also helps to remove the yellowish tint from these old optics, ''vintage lenses''. Besides, people often use cheap so called ''UV LEDS'', that do emit not lower than 385 nm at best. [link] [comments] |
| What caused the circular formations in these rocks? Posted: 06 May 2022 04:29 PM PDT Here are some photos of the rocks I'm asking about. I hope they are detailed enough, I photographed them from afar. This is from a Portuguese beach. I go there often and I always wonder what caused these formations, because they are so distinctly circular and there are so many of them. Most are concave, some have a slightly convex interior.
