| Does your blood type influence how sick will you get with the common cold? Posted: 11 Jun 2020 05:21 AM PDT I have read an article stating that people with A blood type tend (on average) get more sick with COVID19 than people with O type blood. I wonder if the same applies to other types of coronaviruses. Do I also tend to have a worse time with common cold if I have A type blood? [link] [comments]  |

| When people forge metal and parts flake off, what's actually happening to the metal? Posted: 11 Jun 2020 06:04 AM PDT Are the flakes impurities? Or is it lost material? And why is it coming off in flakes? [link] [comments]  |
| Why can't we throw lightweight things very far away? Posted: 11 Jun 2020 06:30 AM PDT I never understood why I can throw an apple very far away but not a piece of cotton. It's lighter so I should be able to make it reach higher speeds with less force. But if something is too heavy I can't throw it far away either. Is there a soft spot for weight? [link] [comments]  |

| Posted: 11 Jun 2020 08:16 AM PDT Has scavenging for seeds from bird feeders or spotting free seeds on the ground been conditioned in to the avian population or is there some natural behavior this stems from? [link] [comments]  |
| Do any other animals with physiology that permits apply pressure to wounds instinctually as we do? Posted: 11 Jun 2020 08:14 AM PDT I just got done watching a guy crowbar himself in the noggin and it struck me (I went there) that people have a natural and rapid reaction to apply pressure to a wound which got me thinking whether this is a uniquely human trait. I realise I may have incorrectly assumed that this reaction is instinctual rather than learned. I suppose it's probably limited to primates in general if it exists at all in other species. I just found it interesting because it's an extremely specific adaptation. Unlike having a reaction to intense heat to withdraw a limb, which any animal can do, it requires having the physiology and dexterity before the adaptation becomes advantageous. [link] [comments]  |

| How to get a Lagrangian when there are constraint forces that do work? Posted: 11 Jun 2020 08:00 AM PDT Say you have a spring-mass system that has a rest length of 0 and is confined to a rod that rotates at a fixed angular frequency w. The constraint force that keeps it rotating at the fixed frequency does work when the radius changes, yet Newton's law for the radial component of motion gives the same equation as the usual T-V Lagrangian written in polar coordinates (assuming phi-dot is constant). But, I thought this Lagrangian only works when constraint forces don't do work - what's going on here? [link] [comments]  |
| Posted: 10 Jun 2020 05:47 PM PDT As I understand it, the early Earth was struck by a Mars sized object creating the Moon. I feel like that's close enough in size to at least change Earth's orbit by some appreciable degree depending on how fast the impact. How does Earth stay in stable orbit after that?

| Is there a system that controls where the blood flows in the brain? Posted: 11 Jun 2020 07:04 AM PDT Hi all, Is there a system in the brain that controls how much blood each zone gets in the brain. Let's say, your sitting down, listening and talking, does your muscle control system gets less blood than the language processing part? If so what system controls this? Thanks [link] [comments]  |

| How loud would a nuclear explosion be? Posted: 11 Jun 2020 12:26 AM PDT Question in the title. What would you actually hear? Also, would you perceive the shockwave as sound? Would it deafen you at a certain distance? [link] [comments]  |

| Do (urban) magpies have a special call to warn about predators? Posted: 11 Jun 2020 02:17 AM PDT Context: I spend a lot of time on my balcony so I am constantly paying attention to the environment around me. There are lots of magpies that I usually notice only visually until yesterday when I heard a song that I couldn't recognize. I looked under the tree they were sitting and there was a cat (common known urban predator for birds) and 3-4 magpies were having the same loud call (that sounded rather alarming) and were following the cat (flying from tree to tree while issuing the same call). As soon as the cat disappeared and ran behind bushes (probably out of sight for them) the call stopped. I normally don't see cats roaming free on the street so I am pretty sure the magpies were trying to warn their fellas about it. Can anyone tell me more about this subject or am I just getting crazy for listening too much to birds and their songs? 😅 [link] [comments]  |

| Why do orange skins dry out so quickly after peeling them? Posted: 10 Jun 2020 11:44 PM PDT I was just noticing the oranges I've had for about a week or two - at the time I'm peeling them they're fleshy and soft, but after being peeled they'll dry out completely within a day or so. I'm sure there's some moisture transfer going on but it's not very apparent to me what the mechanism is. Is the skin of the orange attached to the fruit juices in some way? Or are there living cells in the orange rind that die once peeled? [link] [comments]  |
