Are there any extinct animals recorded in cave paintings that we don't otherwise know about? Posted: 09 May 2022 08:18 AM PDT Could there be cave paintings containing animals we haven't found fossil records for yet?

Where was the Hawaiian islands/hotspot located in the Mesozoic? Posted: 08 May 2022 03:49 PM PDT Where was the Hawaiian islands/hotspot located in the Mesozoic? I believe that the current islands didn't exist until the Cenozoic, and that the oldest of the Emperor Seamounts existed during the Cretaceous period, but I have no idea where the hotspot was located or when it was created. Also, I'm wondering what climate the islands were. submitted by /u/ZanyRaptorClay [link] [comments]

Rest vs. exercise after a flu shot? Which option would result in fewer side effects? Posted: 09 May 2022 12:13 AM PDT Hey y'all. Just got a flu jab. Should I rest and deal with side effects or head out for an hour long walk? I have read that exercising after a flu shot can give a better immune boost. But I want the least side effects possible. So would a better immune response equal more side effects? I hope this makes sense. Please direct to the right sub if not the right place to ask.

How does a brain with 20:20 vision develop vs one with 20:10 vision? Posted: 09 May 2022 06:38 AM PDT So my thought is simple, If you see clearer at a further distance vs avg population, then your brain in turn has to process more data. Over the growth of a child, I have to imagine that much keener sight would cause a noticeable difference in ability to process information as you have to always process more. Any input on this curiosity? submitted by /u/laxmolnar [link] [comments]

Why do ion engines prefer high molecular weight propellants, but nuclear thermal rockets tend towards low MW propellants? Posted: 08 May 2022 04:06 AM PDT I've recently reading about new advances in rocket propulsion technology. Leaving aside other considerations like ionizability, chemical stability, etc., why does either propulsion system prefer the "opposite" extreme of propellant molecular weight? From what I gather online, ion engines tend towards xenon, while the proposed nuclear thermal rockets in development generally adopt hydrogen. Am an engineer myself, so feel free to explain in depth. Thanks! submitted by /u/draconicsheep123 [link] [comments]

If a planet is tidally locked and in the relative habitable zone of its star, would the tidal forces be strong enough to increase volcanic activity on the side of the planet facing towards the star?

Why are there true-to-seeds and not true-to-seed plants? Posted: 07 May 2022 11:07 PM PDT I recently learned how avocados are not true to seed plants and by that meaning planting them doesn't give you the same fruit. This is very intriguing and strange.

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?

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 submitted by /u/tommy02862001 [link] [comments]

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? submitted by /u/East_Entrepreneur513 [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.

Are lobsters' lives limited only by their ability to moult, and could they theoretically reach any size or age? 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 submitted by /u/AnOddEgg [link] [comments]

Optics containing thorium do yellow over time, because of the alpha decay damages the glass lattice. Annealing can help to get rid of the discoloration. People also report that exposure to UV radiation helps. How does UV radiation help to make the glass visually transparent again? 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. How does UV radiation help with making the thoriated yellowed glass visually transparent again? submitted by /u/HackingDutchman [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. submitted by /u/mossgreen225 [link] [comments]

Is there a consensus in the scientific community that the perception of time passing is a sense similar to sight & hearing? The University of Dublin recognizes time blindness as a condition and accommodates students with it. Is this rare? Posted: 05 May 2022 05:58 PM PDT Sights & sounds can be measured in terms of brightness or loudness. Periods of time can be measured by length - e.g. minutes or months. People with time blindness cannot accurately sense or measure the passing of time without external aid (a clock or timer - this one is designed specifically for them). This recent study (March 31/2022) on the pupils of people with aphantasia (the inability to visualize images) proved what millions afflicted with it have been saying since the 1800's: that they cannot "see" anything with their mind's eye. For them, that eye is blind. Similarly, time blindness is also believed to be a sensory issue by those who have studied it, but unlike aphantasia, it has yet to be proven scientifically. For people with time blindness, starting to use a timer for daily tasks can feel like putting on a pair of needed glasses for the first time. They need an aid to monitor the passing of time the way others can naturally. Was aphantasia a "theory" before the scientific proof was found, and is now a proven sensory deficiency? Does the "timer" part of the brain need to be discovered and a deficiency noted in the time-blind in order for their condition to be validated, or does science accept time perception as a sense like sight or hearing, without physical evidence of the mechanism? This research university (University of Dublin) recognizes time blindness and accomodates students with it. Is this recognition rare/emerging in the scientific community? submitted by /u/Dependent-Army4891 [link] [comments]

Does birdsong carry any information that we've been able to "codify" (not sure the word I'm looking for) to any extent? As opposed to the assumption that it's "Here I am, Here I am" over and over? Posted: 05 May 2022 02:52 PM PDT When I hear a bird vocalize repeatedly, it sounds very "similar" to itself, which leads me to think of it being a very basic "Here I am, here I am" sort of thing. But I also remember reading the roots of the word "barbarian", where folks thought certain other folks were just saying "bar bar bar". And nevermind that silly comparison, it was just what prompted me thinking about this just now. I know some birds have various vocalizations for various settings. Crows have their caw and their rattles and clicks. But even here, the caws have significant variation, in the single caws and in the sequence of caws, their spacing/etc. Of course so do the rattles and clicks. How deeply, if at all, do we understand significance of "some series of rattles" vs "some other series of rattles." An answer could be "There is no significance, they are basically automatons" but... I suspect that's just too convenient and human-centric. Why bother with all that different subtlety if it's just "I'm here, I'm here, I'm here." Or "My territory, my territory." Has there been any work done on attempting, I guess what I would have to call translation, of various bird's vocalizations? And to what degree have we gone the deepest with this? The robins in my area, probably all robins, have this long sequence of chirps, which always maintains the identifiable structure, but which has a huge amount of variation. I can't help but feel that there could be very nuanced information encoded in this variation. They also do a sharp single chirp at various times, though always when they're getting their babies out of the nest. I'm wondering if anyone could discuss it or point me at studies related to this or just tell me I'm bird-brained! submitted by /u/salfkvoje [link] [comments]
