| Where and how is energy stored in the body? Posted: 15 Jan 2021 05:03 AM PST And an optional follow-up question - we have days when we feel focused and energetic and can take on a variety of different tasks, both physical and mental, throughout the day but we also have days when we feel like we can't get out of bed. What causes this and why do we sometimes "wake up" after a cup of coffee or an energy drink? Is energy something specifically definable and do we expend the same energy capacity for both physical and mental tasks? [link] [comments]  |
| What determines when a viral infection is no longer contagious? Posted: 15 Jan 2021 05:16 AM PST Covid-19 patients can test positive for up to months after being infected but the CDC guidelines state that the virus is most likely not contagious after 10 days. How is someone who still has detectable amounts of covid-19 in their nose or saliva no longer able to pass it on to someone else? [link] [comments]  |

| Special relativity from multiple simultaneous perspectives? Posted: 14 Jan 2021 11:44 PM PST My understanding: Due to special relativity, if one atomic clock is on a space-craft moving very quickly (closer to the speed of light I suppose), and another atomic clock is on the planet standing still, the time on both of them will appear different. My question: How does this reconcile with multiple points of view of the same phenomenon? For example, if there are three points of perspective, A, B, and C. If each point of perspective watches the space-craft travel from a different vantage point, and then they all compare their notes to the actual data on the atomic clock from the space-craft, what will happen? Assume perspective A is at a fixed point behind the space-craft, perspective B is at a fixed point in front of the space-craft, and perspective C is at a fixed point to the side of the space craft. Once the space-craft is done traveling, wouldn't they all have different experiences due to the space-craft moving in different directions relative to the direction/speed of light? Due to the varied viewing angles, the light should behave differently and have a slightly different perceived speed from each vantage point, shouldn't it? For example, wouldn't the clock on the space-craft be faster than the clock at one vantage point, but slower than another? Yet if all the three vantage points were fixed relative to each other, how could they reconcile their data? [link] [comments]  |

| Could the technology behind mRNA vaccines be used to combat cancer? Posted: 14 Jan 2021 05:49 PM PST For example, could they put mRNA instructions for apoptotic proteins or other inhibitory/interference proteins to a cancer cell's pathways in order to fight it from the inside out? I'd imagine this could either be injected directly into the tumor or the nanoparticle could be modified to have antibodies or other small molecules with high affinity for cancer specific receptors? This would circumvent some cancer's ability to use efflux pumps to export chemotherapeutics from the cell. [link] [comments]  |
| What happens to competing virus variants in a given area? Posted: 15 Jan 2021 03:57 AM PST So I'm not sure exactly how to word the question, so sorry in advance. We keep hearing about new variants if the Covid virus (the UK, South Africa and Brazilian variants). They are all reportedly more transmissible and are becoming the dominant variant in the areas they were discivered. What happens if there is an equal prevalence of each variant in a given area? Do they mutate further to try and gain dominance? What governs that? Finally is there any benefits or negatives to the human population in those areas (having a virus compete for dominance)?

| What is the oil our skin makes? Posted: 14 Jan 2021 06:52 PM PST Not necessarily sebum, pimples/blackheads, or sweat produced from sweat glands. I've heard "if you pop a pimple, your face produces oil to help protect itself". I guess I just mean the lubricant your body makes. What is human oil, and what is it made out of? [link] [comments]  |
| Posted: 14 Jan 2021 12:14 PM PST I know that the spikes on their face are like gills, but I was wondering more about how that works in comparison to a mammalian respiratory system? [link] [comments]  |
| How do scientists know how continents emerged and collided in the pasts Eons and Eras? Posted: 14 Jan 2021 10:08 AM PST I was watching this video about the the history of the earth and the continental drift and I was wondering "How do scientists know?" I mean, during the Archean Eon there are a bunch of tiny islands floating. What are the clues that they really existed? Or in Pangea, how do they know that India was part of africa, moved in a specific way to then collide with Asia? How is this studied? My guess is that they study mineral core samples and then can see when that place was underwater or above X millions years ago, or if the mineral composition matches another place's it may indicates that those where united in the past. What are other tools used to study this? [link] [comments]  |

| How do scientists measure the inclinatiom of a planet? Posted: 14 Jan 2021 05:39 PM PST I was browsing on reddit and saw a gif of the rotation of the planets. In the gif for every planet every angle of inclination of each planet was written there (for the earth 23° for example). What reference points do scientists use to determine which part is supposed to be on top or to measure how much the planet is lnclined. Does it have to do with the magnetic field each planet has? Or do other planets even have a magnetic field like earth has? [link] [comments]  |
| Can SARS-Cov-2 recombine with other coronaviruses in humans? Posted: 14 Jan 2021 10:10 PM PST Other coronaviruses are well known for recombination events, how about COVID-19? [link] [comments]  |
| Do cells that have been hijacked by a virus skip transcription? Posted: 14 Jan 2021 07:28 AM PST I'm a little confused as I can't find out any information on this - when a cell forms a protein it goes through transcription and translation, in transcription the DNA is converted into RNA - I thought that when all viruses hijack a cell they use reverse transcriptase to convert their RNA into DNA, but this only happens in retroviruses. Do normal viruses remain as RNA when they enter a cell? And if they do, surely they wouldn't need to undergo the transcription stage as their genetic material is already in the correct form for it to go straight onto translation right?

| Can lightning strike above the clouds? Posted: 14 Jan 2021 12:55 AM PST I'm wondering if I built a pole tall enough to go above the clouds and there was lightning. Would the lightning go above the clouds and reach the top or would it go down mid pole. Also, if it can't strike above can it strike sideways if possible? One of those shower thoughts.
