| Does hair actually absorb vitamins, proteins... from shampoo? Posted: 16 Apr 2022 07:36 AM PDT A lot of shampoos contain biotin, vitamin E, Q10, wheat protein, zinc, panthenol, coffein, different kinds of oils and all kinds of stuff. But does hair actually absorb this stuff? Will it make my hair better or it is just a marketing trick? I'm not a expert but I think that hair is basically dead keratin and it can't and won't absorb anything. But I could be wrong of course. Vitamin E and Q10 could improve the condition of my scalp skin if applied on the skin surface but that's probably it. It's better for me to continue to take vitamins in form of tablets or should I buy one of these magic shampoos to improve to quality of my hair? Update: I'm very thankful to you all for your advices, opinions and provided information. I've decided that I will use a chemical-free Bio shampoo from the vegan store after learning about all the chemicals and marketing tricks in the cosmetic industry. Of course it won't give me the ''Ultra Magic Super Soft Shine Hair" but it will get the job done when needed and it's health/nature friendly. [link] [comments] |
| Can a planet with a spin-orbital resonance like Mercury occupy the habitable zone? Posted: 16 Apr 2022 06:51 PM PDT What would it look like? How would the wind/ocean currents behave? [link] [comments] |
| Can we observe humidity and evaporation from a distance? Posted: 16 Apr 2022 06:34 PM PDT I live in a dry climate. I was wondering if it could be possible to create a tool that can view humidity from afar, to locate a pool of water or other source of evaporation. Similar in usage to an IR camera for heat. Sorry if this is a dumb question! [link] [comments] |
| Posted: 16 Apr 2022 09:52 AM PDT So I've heard that getting bitten by the lone star tick will make you allergic to red meat, specifically to saccharide "alpha-gal", present in most mammals, except humans. I wonder why we don't develop this allergy by eating the meat itself. Wouldn't that sugar circulate the body and be detected as foreign anyway? I'm sure I'm missing an important mechanism here, I just can't figure out why the body is fine with it as long as it's exclusively eaten, but after a bite you can't eat it anymore. I'm really curious about this acquired allergy. [link] [comments] |
| How similar were avian/nonavian dinos at KPg extinction? Posted: 16 Apr 2022 09:58 AM PDT 66 million years ago, would biologists have still called the birds dinosaurs? Or were they diverged enough to only say they were "descended from dinos"? What about today? Birds ARE dinosaurs or only their living descendents? For example, mammals are descended from fish but it's unreasonable to say "mammals are fish", right? [link] [comments] |

| does covid bounce of the mask or stay on the mask? Posted: 16 Apr 2022 11:45 PM PDT I've been avoiding touching the outside of the mask, since I assume covid kind of sticks to or lands on the mask. Is this true? Or does covid "bounce off" the mask? Potentially to some degree. [link] [comments] |
| Posted: 16 Apr 2022 07:20 PM PDT I understand that there are several interesting similarities between crocodiles and birds: 4 chambered heart, gizzard, nurturing young, something about the way birds' teeth used to theoretically be connected way back when they used to have teeth. I also understand that there are subtle differences between crocs and lizards: 3 vs 4 chamber heart, splayed legs vs vertical legs, eye socket anatomy, overlapping scales vs. non-overlapping scales, (sometimes) detachable tails. There are also many obvious differences between birds and crocodiles: one lives underwater, the other flies and lives in trees. One has feathers and a beak, the other has scales, a snout, and is cold blooded. One has 4 legs and a long tail, the other has 2 legs and 2 wings and hollow bones. Along with that, there are some very obvious similarities between crocs and lizards: cold blooded, scaly, 4 legged predatory reptiles with long tails and without shells. However, I am having trouble wrapping my mind around the decision that the few similarities between crocs and birds outweigh both:
It seems like taxonomists just agreed on this wild conclusion to be edgy and interesting. Can someone enlighten me on how such an unintuitive result came to be widely accepted? In some ways, it seems to undermine taxonomy as a science. [link] [comments] |
| Posted: 16 Apr 2022 09:49 AM PDT I understand that heart muscle is thickened/enlarged in all these cases, so why are there so many distinctions? Would anyone explain to me the differences in the simplest possible way? I got interested in this, but I'm a total layman in medicine or biology. Thank you. [link] [comments] |
| How would lasers and plasma interact with a strong magnetic field? Posted: 16 Apr 2022 08:01 AM PDT So I'm working on a sci fi ttrpg where both lasers and plasma weapons are a thing as are force fields (electromagnetic fields), but trying to find out how they all interact has been somewhat difficult. Would a strong EMF have any impact on the permeation of lasers or plasma? Would there be any unique or cool side affects with said interaction? [link] [comments] |
