| Posted: 19 Feb 2021 08:13 AM PST How important is the first year for immune system development and "exposure to germs"? Once this child begins post-pandemic activities/daycare/generally higher exposure to the world, will their immune system eventually strengthen and catch up? Will they experience a lot of illness for a while? Imagining an example of an infant born last Spring who has essentially been in quarantine for 9+ months with little to no socialization with other children, adults, playgrounds, daycare, the outside world.

| Was the "seasonal flu" a phenomenon before the 1918 Flu Pandemic? Posted: 19 Feb 2021 12:48 PM PST I was reading an article that casually dropped this paragraph:
Were seasonal flus not a thing prior to 1918? Did urban dwellers and other people in 1910, 1850, 1600 not head into winter half-expecting to catch the flu? [link] [comments]  |
| Is baby weight at birth indicative of later frame size as an adult? Posted: 20 Feb 2021 07:05 AM PST If one baby is heavier than the other at birth but still within the normal range, does that mean that baby will become a bigger framed/boned adult later? I found information that longer babies do become taller adults, but nothing about weight differences in the normal range (not talking about underweight babies). [link] [comments]  |
| Can dolphins and whales sense depth, and do they know when they've gone too deep? Posted: 19 Feb 2021 06:30 AM PST Human divers can feel a squeeze as they dive deeper, but once they equalize, they don't really feel the depth. Oxygen gets toxic when it's too concentrated (gasses compress at depths and this would concentrate any oxygen a mammal brings down). I assume aquatic mammals would die if they went down too far, much like a human divers would. Can they tell when they've gone too far, or does it just not happen because they would run out of air before they got down there? Can they get decompression sickness? [link] [comments]  |
| Why is the microstrain of Rutile smaller than Anatase? [Material Science] Posted: 20 Feb 2021 06:33 AM PST Could factors such as crystal structure and stability attribute to such observation? [link] [comments]  |
| Why does pulsatile flow depend on an energy gradient, not a pressure gradient? Posted: 20 Feb 2021 07:29 AM PST I don't get how this isn't a pressure gradient. Is it that that capillaries are truly so narrow it makes more sense to think of it as particle movement rather than fluid dynamics? [link] [comments]  |
| Can Pi stacking occur when two aromatic rings are not parallel? Posted: 20 Feb 2021 06:20 AM PST Can Pi stacking occur when two aromatic rings such as tyrosine are in a non parallel confirmation? With one being planar and the other at a slight angle of approx 45 degrees in relation to the top aromatic ring? Both rings have nothing between them and the aromatic rings still are within the same vertical plane [link] [comments]  |
| What stops lesions in the bowel (such as from a polyp removal) from getting infected? Posted: 19 Feb 2021 10:51 PM PST I was watching some videos of colonoscopies and polyp removal, where gastroenterologists remove polyps (growths in the intestines) from the walls of the colon using a snare - pretty cool stuff! Once these polyps had been removed, there was what looked like an open wound bleeding into the colon. The colon is, naturally, going to fill up with feces and other nastiness at some point soon. If an open wound of the skin gets in contact with feces, I imagine it's pretty likely to get infected. Why doesn't this happen when the bowel wall is breached in this fashion? What stops bacteria from getting into the circulation and causing something like sepsis? Appreciate any answers on this, thanks! [link] [comments]  |
| Posted: 19 Feb 2021 10:04 PM PST Hi! I'd just like some clarification on some phenomena involved. So the Meissner effect and quantum locking explain why levitation occurs as a superconductor is cooled below its critical temp. However, BCS theory and flux pinning explain why a superconducting material possesses its superconducting abilities? Also, when talking about BCS and flux pinning do I assume it's only applicable when the superconductor is in its cold state? Thanks! [link] [comments]  |
| How does Ingenuity (The Mars Helicopter) fly on Mars with such a thin atmosphere? Posted: 19 Feb 2021 05:44 PM PST Relative to earth does it require a more significant RPM to achieve flight? How similar is the viscosity of the air on Mars to earth? [link] [comments]  |
| What are the danger zones demographically with increased chance of successful suicide? Posted: 19 Feb 2021 10:16 PM PST I remember hearing somewhere that men with bipolar in their late 40's, early 50's are very at risk, but i cant quite remember exactly. [link] [comments]  |
| Posted: 19 Feb 2021 06:04 PM PST How do allergy shots differ from just being exposed to the allergen? I've read that the shots give a tiny dose of the allergen, not enough to cause a full blown reaction, but enough to gradually desensitize the body to it. But if I'm already being bombarded with the allergen, say cat dander and dust mites, then what good does it do to sprinkle a little extra allergen on top in the form of a shot? [link] [comments]  |
| Posted: 19 Feb 2021 09:03 PM PST I was watching this video of cats responding to videos of their owners using a cat filter: It seems to me that they react with shock and turn to their owners to see if they have really transformed into a cat or not. I found this interesting because I thought cats fail the mirror test: https://www.hillspet.com/cat-care/behavior-appearance/do-cats-understand-mirrors Can anyone explain the cats reaction in a way that doesn't require them to understand they are essentially looking into a mirror of sorts?

| What is the point of Brillouin Zones? Posted: 19 Feb 2021 07:05 AM PST I am watching this video: https://www.youtube.com/watch?v=1hWayXcwFww Why do we want the reciprocal lattice points to be in the first Brillouin Zone? Are we trying to capture the entire response, or are we trying to only capture parts of it as in its entirety it would be too much data to handle? Might be stupid questions but I wanna try and understand this. [link] [comments]  |
| Why are the functions of brain regions so consistent? Posted: 19 Feb 2021 05:31 PM PST In my understanding, the brain can be divided into regions with different cellular structures. Are those structures what determine the function of that region? Why are the locations consistent enough to map functions to locations? Are there some people with 'misplaced' brain regions?

| Posted: 19 Feb 2021 04:23 PM PST E.g why is it easier to recognise someone when they are wearing masks because of COVID I can tell who it is but if I was to look at photos taken in the army, where they put black lines over their eyes, I can't recognise the person? [link] [comments]  |
| Why is vitamin d required for calcium transport? Posted: 19 Feb 2021 03:05 PM PST I'd like to get detailed mechanisms of actions. For example in the gut it increases absorption, but through what pathways? Similarly, how does it help bind calcium into the bone matrix? I'd like to get as technical of an explanation as possible.
