- What's the difference between comets, meteors, meteorites, meteoroids, and asteroids?
- Vaccines like the current Covid ones target the virus’ spike proteins, which mutate a lot. Why haven’t they developed a vaccine that targets the nucleocapsid proteins instead?
- Why do we need Vitamin K in our body?
- Why are laparoscopic surgeries often performed with an incision right by the belly button, instead of just elsewhere on the abdomen?
- How does the process of creating the COVID vaccine differ from the process to create the flu vaccine each year?
- Do influenza vaccines over a lifetime confer progressive immunity to new/recombined variants?
- Why should B decay to electrons or muons at the same rate?
- Can the same virus variant arise spontaneously in more than one place?
- Why do rivers "Breathe", Change in depth, throughout the day?
- Do people who lose their dominant hand become "the-other-handed"? What about other organs where dominance exists, like legs, eyes, etc.?
- Is it possible for binary planet's to be habitable?
- Will there be a COVID-19 vaccine for big cats or other animals kept in zoos that are susceptible to COVID-19?

| Posted: 13 Apr 2021 05:25 AM PDT It seems like the belly button would be more difficult to clean and more likely go develop an infection. Is it done just for aesthetics cause it's easier to obscure the scar? [link] [comments]  |

| Do influenza vaccines over a lifetime confer progressive immunity to new/recombined variants? Posted: 12 Apr 2021 03:28 PM PDT So influenza shuffles its neuraminidase/hemagglutinin surface markers through genetic recombination shift/drift events to escape immune clearance. As humans we have been immunizing every year for the most common strains of that year. Over a lifetime, however, and assuming fidelity to vaccinations, will an individual have the robustness of an immune response to new strains of flu? Are the gains we get each year progressively adding to a repertoire that has sufficient overlap to even newly recombined strains? Thank you! [link] [comments]  |
| Why should B decay to electrons or muons at the same rate? Posted: 12 Apr 2021 08:28 PM PDT The description of the B meson decays coming out of the LHC is that the standard model prediction is that the probability of decaying by producing an electron pair is the same as decaying with a muon pair. Why doesn't the difference in mass affect the probability in these decay modes? I'm thinking of two things. First aren't there kinematic factors that depend on the masses of the decay products. Second doesn't the mass of the particles affect the higher order quantum effects that can differentiate between the two (e.g. the electron and muon have different g factors) [link] [comments]  |

| Why do rivers "Breathe", Change in depth, throughout the day? Posted: 12 Apr 2021 01:15 PM PDT Was sitting next to a river a few days ago, and I noticed a tree trunk sticking out of the water, very clearly visible. I look down at my phone for about 20 minutes and look back up, The trunk was noticeable more submerged. As I kept looking down and back up over the course of maybe more than an hour, eventually the trunk was fully submerged. The next day I walk by the same river, at the same time and the trunk is back where it is. This made me wonder why do rivers "breathe". Does anyone have an answer, would love to know.

| Posted: 12 Apr 2021 09:23 AM PDT If yes, does "shift" in one organ's dominance affect dominance in other organs as well, even if they're intact? [link] [comments]  |
| Is it possible for binary planet's to be habitable? Posted: 12 Apr 2021 02:15 PM PDT If so, would it be possible for life to pass between them through events like astroid collisions? Would there need to be some halfway gravity source, like a moon? I'm going to use this as a part of a story I'm writing, and I want to keep it as realistic as possible, so if there are any intresting things that someone living on a binary planet would have, please let me know.

| Posted: 12 Apr 2021 11:20 AM PDT I remember reading a while ago that several big cat species at the Bronx Zoo tested positive for COVID. I believe they thought other species might be vulnerable to COVID as well. [link] [comments]  |
| How do mRNA vaccines affect people with Oral Allergy Syndrome (OAS)? Posted: 12 Apr 2021 12:42 PM PDT Oral Allergy Syndrome, sometimes referred to as Pollen Fruit Syndrome (PFS) is the result of your immune system confusing proteins found in different fruits with proteins found in certain kinds of pollen. This can result in an allergic reaction to the raw fruit, but cooked fruits are often safe as the protein is broken down. Unlike traditional vaccines, mRNA vaccines help your body produce a protein that triggers an immune response. Would people with OAS be at risk for additional/more severe adverse reactions? Are mRNA vaccines like to be more effective, less effective, or is there no correlation/causation between OAS and mRNA vaccines? [link] [comments]  |
