| Does the sun have a solid(like) surface? Posted: 20 Mar 2021 07:55 AM PDT This might seem like a stupid question, perhaps it is. But, let's say that hypothetically, we create a suit that allows us to 'stand' on the sun. Would you even be able to? Would it seem like a solid surface? Would it be more like quicksand, drowning you? Would you pass through the sun, until you are at the center? Is there a point where you would encounter something hard that you as a person would consider ground, whatever material it may be? [link] [comments]  |
| What cells in my body are making the spike protein after I get an mRNA vaccine? Posted: 20 Mar 2021 02:45 PM PDT Is it all of them? Just the cells in the muscle that they injected into? Or is just white blood cells? [link] [comments]  |
| How does an "undetectable viral load" prevent the transmission of HIV? Posted: 20 Mar 2021 05:53 PM PDT It's been widely publicised that a person with an undetectable viral load of HIV is unable to transmit the virus to another person, but I've never seen an explanation as to why that is. I would like to understand why such a small, but non-zero, amount of the virus is not infectious. Is it just a consequence of probability, meaning that the number of HIV particles is so low that the odds of any single one successfully infecting a host cell are virtually zero? Or do infections occur, but the very small number of them allow the immune system to eliminate them before too many cells are taken over? [link] [comments]  |
| Has there recently been more volcanic activity than usual? Posted: 20 Mar 2021 02:24 PM PDT Is it just me or does there seem to be an increased number of eruptions lately? If so, is it a sign of something potentially bigger such as the big California quake or even perhaps a Yellowstone eruption? [link] [comments]  |

| How many cell's distance is the average human tissue cell away from a capillary? Posted: 20 Mar 2021 12:06 PM PDT I get that it's a broad question and it would probably be different in bone vs muscle, but I'm assuming not every cell is directly adjacent to a capillary. Roughly how many cells would or could be between 2 capillaries and still get adequate O2, waste removal, etc? Thanks! [link] [comments]  |
| How are rockets test fired without moving? Posted: 20 Mar 2021 09:53 PM PDT How is all of the energy the rocket produces which would normally increase it's velocity upwards absorbed or dissipated? My first thoughts would be attaching a large amount of mass to the rocket somehow or putting a large amount of mass above it that it is not capable of breaking through, but I feel like it would have a more advanced answer than that.

| Can someone explain the steps of reverse transcriptase in a retrovirus? Posted: 20 Mar 2021 05:17 PM PDT Hello all, I've been looking around for good sources that can explain the process of reverse transcriptase in a retrovirus, but I can't find much that I can understand. Can anyone explain what the steps are for a retrovirus getting its RNA to DNA, preferably with the main enzymes involved? Thank you in advance. [link] [comments]  |
| Do bouncing ball videos help children learn to read? Posted: 20 Mar 2021 12:50 PM PDT As its wiki article?wprov=sfti1) states, "The bouncing ball is a device used in motion picture films and video recordings to visually indicate the rhythm of a song, helping audiences to sing along with live or prerecorded music." I'm at the stage in life where I'm helping a young child learn to read, and my suspicion is that bouncing ball videos do a good job showing the child what sounds correspond to what letter combinations (at least generally, in this highly irregular language). Is that suspicion accurate? [link] [comments]  |
| Are the current coronavirus vaccines effective against the known variants? Posted: 20 Mar 2021 09:29 AM PDT My parents both recently received the AstraZeneca vaccine and I have received the Pfizer one. I am wondering if any data has come out on the different vaccines and their efficacies against the current known variants (UK, Brazil, South Africa in particular). [link] [comments]  |
| Posted: 20 Mar 2021 12:39 PM PDT If I had a radioisotope which can only decay through the process of Electron Capture, and I somehow managed to totally strip it of every single orbiting electron before it decayed, what would happen? Would it decay? If so, how? Or are there no isotopes like this - in other words, there's just a remote chance it could do something else (if so, would this affect the half life at all?)

| Why don’t all cell phones receive the same calls? Posted: 20 Mar 2021 09:26 PM PDT Cell towers do not know where your phone is; signals are broadcasted indiscriminately toward all devices. how your phone filter out data meant for every other phone on the network and only receive the data meant for itself? thats way too much to be done internally by the processor right?

| Isostatic rebound: How do rates of rebound change over time? Posted: 20 Mar 2021 02:51 PM PDT I have been trying to figure out what Greenland might look like after the ice cap melts in a hypothetical future. And one of the things to take into account is isostatic rebound. And I'm assuming that immediately after ice retreats from a region, if rebounds a lot faster than it does thousands of years later, like most of the world today. Are there any estimates for how fast the ground would rebound immediately following the loss of ice? And are there any estimates for how this rate would change over time? [link] [comments]  |
