| 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? And if there were, how would we tell if the animal being depicted was actually real and not some made up creature? [link] [comments] |
| 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. [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. Thanks [link] [comments] |
| 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? [link] [comments] |
| 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! [link] [comments] |

| When Scientists discover new species how they determine which one is male and which one female? Posted: 08 May 2022 04:00 AM PDT If in some species males also can be pregnant then what tell scientists that this one should be called male and other one female? [link] [comments] |

| 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. Aren't we all the product of our DNA. And isnt that DNA embedded within the seed? [link] [comments] |
