| Posted: 01 Feb 2022 02:40 AM PST Much of the public health messaging I see around COVID, Flu, and other common sicknesses emphasizes not touching your face with dirty hands. When I hear that, I hear "don't touch your eyes, the inside of your nose, or your mouth"/your mucous membranes. Is this right or is your cheek genuinely a dangerous place to touch and if so, why? Is there some way that things move from your cheek to your eye easily? Is your cheek significantly riskier than touching say, your shoulder? I understand that we now know that formite transmission is not the dominant mode of transmission for COVID (seems to be quite rare), but for other similar sicknesses, I still have this question.

| Are there actual wild horses in the Americas or are they all feral domesticated horses? Posted: 01 Feb 2022 06:38 AM PST Has anyone ever brought actual wild horses to the Americas? And are there wild horses still in Asia? Or have they been bred out with domesticated horses to the point that all the horses in the world are basically domesticated? [link] [comments] |
| Why don't single prop aircraft continuously roll? Posted: 01 Feb 2022 07:24 AM PST Helicopters have tail rotors to balance the force generated by the main rotor, without which they'd keep spinning. But why don't this phenomenon affect single prop aircrafts like ww2 fighters? Shouldn't they be continuously rolling? Another side question, since the tail rotor can be used to spin the helicopter right or left, how do helicopters without one like KA-50 do that? [link] [comments] |
| Why are submarines and torpedoes blunt instead of being pointy? Posted: 31 Jan 2022 06:30 AM PST Most aircraft have pointy nose to be reduce drag and some aren't because they need to see the ground easily. But since a submarine or torpedo doesn't need to see then why aren't they pointy? Also ww2 era subs had sharo fronts. [link] [comments] |
| Will patients in a clinical mRNA HIV vaccine trial show up as HIV positive in testing? Posted: 01 Feb 2022 12:04 PM PST First patients vaccinated in clinical trial of HIV experimental vaccine that uses Moderna's mRNA technologyhttps://edition.cnn.com/2022/01/31/health/moderna-mrna-hiv-vaccine/index.html [link] [comments] |
| To what extent do most cultures recognize the same specific emotions? Posted: 31 Jan 2022 09:57 PM PST Some cultures only have words for red, white, and black, while other cultures have words for red, orange, yellow, etc.—does the same hold for emotions? Put another way: in primary schools, there are posters with cartoon faces caricaturing important emotions, but would an analogous poster on the other side of the world be likely to have the same categorization?

| Why is cancer so much more prevalent in men? Posted: 01 Feb 2022 09:36 AM PST "The cancer mortality rate is higher among men than women (189.5 per 100,000 men and 135.7 per 100,000 women). When comparing groups based on race/ethnicity and sex, cancer mortality is highest in African American men (227.3 per 100,000) and lowest in Asian/Pacific Islander women (85.6 per 100,000)."

| Posted: 01 Feb 2022 08:56 AM PST I understand what a less robust immune response means, but I haven't seen an explanation or breakdown of what the actual data shows we can expect the level / type of protection to actually be. Will it have any benefit for kids in this age range, or is it simply priming the kids for the possible effectiveness of a booster when it becomes available? Do they show a reduction in illness / hospitalization / transmission? "Less robust" is not very clear! Thanks so much! [link] [comments] |
| Posted: 31 Jan 2022 09:51 PM PST Since they spend 23 earth years on Miller's Planet what would it look like to Romilly who was still on The Endurance? Would he still see the ship in space heading towards the planet for years or would he not be able to see them? [link] [comments] |

| Is hyperbaric oxygen possible on a planetary level? Posted: 01 Feb 2022 07:05 AM PST Pressurized oxygen on a planetary level. Is that possible? [link] [comments] |

| Does this indicate positive (effective) covid vaccine results in under 24 month olds? Posted: 01 Feb 2022 03:17 PM PST If you scroll down a bit to where they discuss non-inferiority. I mean 'effective' in terms laypeople mean it, in case there's a medicine specific usage that I might otherwise imply. Thank you [link] [comments] |
| What *exactly* do we mean when we say that a nucleus is 'stable'? Posted: 01 Feb 2022 02:51 PM PST I am trying to reconcile the following statements together that I have gleaned: 1) Thanks to quantum effects, any interaction or process that is energetically favorable, must happen with nonzero probability due to the inherent uncertainty in the universe (i.e. Heisenberg) 2) Based on the binding energy of nuclei, the most energetically favorable nucleus is that of Iron-56, as it has the strongest binding energy. 3) Despite those two statements, many other nuclei are (colloquially) listed as 'stable', such as Carbon-12 or Oxygen-16, despite not being as energetically favorable as the aforementioned Iron nucleus. Would I be correct to state that stability, as is generally used, implies stability over only a subset of potential quantum interactions? If so, how do nuclear physicists define 'stability'; over what subset of quantum interactions is stability being considered? [link] [comments] |

| Posted: 01 Feb 2022 12:30 AM PST Hello there scientific reddit community. :) There was something bothering me while I was diving into the beautiful images Voyager 1 took. You see, planets like Saturn have these amazing looking rings. They are always shown as these beautiful striking "solid" elliptic planes. However, the rings are comprised of rocks and ice. Therefore, I was wondering. Do the rings look like that in pictures because of long exposure? Or do the objects in the rings travel so fast that they are constantly emitting light? In other words; what would the rings look like in real time; if you would observe them directly? And why would they be observed as such? I tried my way to Google myself to the answer to this particular question; but I failed to find a clear answer. Looking forward to your insights. Thank you! [link] [comments] |
| Why do rectal veins bypass the liver? Posted: 01 Feb 2022 01:04 AM PST Apparently that's why suppositories work, but how come the veins from the dirtiest place in the body skip the cleaning organ? [link] [comments] |

| Why doesn’t electric resonance imaging/ nuclear electric resonance exist/work? Posted: 31 Jan 2022 06:14 PM PST Magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) are both powerful medical and biochemical tools. From what I understand both rely on the magnetic spin properties of particles, can a similar principle work with the electric charge inherent in particles? Why/why not? [link] [comments] |
| How are vaccines tested for children? Posted: 01 Feb 2022 01:56 PM PST Just reading about Pfizer applying to have its Covid vaccine eligible for children, and I'm wondering what drug trials look like for children. It seems like there are ethical implications. How are these drug trials run? How are children selected? [link] [comments] |

| Why do different viruses trigger different immune responses ? Posted: 31 Jan 2022 02:46 AM PST Hello fellow redditors, My question is: Why do some viruses trigger extreme immune responses ? It probably has something to do with the membrane proteins of the viruses and which cell receptors those membrane proteins of the virus can bind to, but why do viruses like Ebola trigger such an extreme immune response that certain messengers are released to such an extent that the vascular permeability skyrockets and internal bleedings occur ? thanks for your answers in advance [link] [comments] |
