- If humans colonized another planet with substantially longer days than on Earth (ex: 36 hours), would our sleep/wake cycles naturally adjust to 24/12 hours respectively over time to accommodate the new norm, or would the recommended 16/8 hour cycle still apply?
- How is the average temperature of a country measured?
- When you contract an unknown disease like the new Chinese coronavirus where means of transmission and virulence is unknown, how do doctors care for you? Do you become a Bubble Boy?

| How do scientists discover viruses in glaciers/ice? Posted: 23 Jan 2020 03:58 AM PST I was reading a post about scientists discovering an ancient virus in a Tibetan glaciers? How do they do that? Do they pick random chunk of ice and analyse them? How does that work? [link] [comments]  |

| How is the average temperature of a country measured? Posted: 23 Jan 2020 05:19 AM PST I can't figure out how the average temperature of a large area or country can be made independent of the number and locations of its weather stations. Is each station assigned a local area, so that it's possible to interpret the set of measurements as a temperature field over which one can average? If so, how are the local area boundaries determined? [link] [comments]  |

| How do viruses hone in and bind to their host? Posted: 22 Jan 2020 05:32 PM PST Viruses technically aren't alive, so they cannot move or even think by themselves. How do viruses know that it is near a compatible host, go to it, and correctly align itself to bind to the hosts receptors? [link] [comments]  |
| How does sublimation turn water from a solid to a gas without it being a liquid in between? Posted: 22 Jan 2020 02:48 PM PST If turning ice to steam or air vapor is just a matter of adding heat (aka energy), wouldn't water *have* to go through a liquid phase-even if for just an instant?

| How do they treat blood after donation? Posted: 22 Jan 2020 10:24 PM PST I assume they take it from veins which means the blood is low on oxygen. Do they add oxygen to it later? How else is it treated before use? [link] [comments]  |
| Do we know what the tallest mountain ever was? Posted: 22 Jan 2020 01:09 PM PST Can we estimate the size of past mountains ranges based on tectonic speed? [link] [comments]  |
| Why and how is it possible that the immune system could be affected by stress (or anxiety)? Posted: 22 Jan 2020 08:58 AM PST Sorry in advance for the stupid question, but this actually is something personal that I've been trying to work on. And, although I'm not proud, my post history shows how I feel like I'm running out of options. Mostly because I don't understand how something that feels as if it's all in my head can have long term effects. Maybe if I get a better understanding, it can hopefully lead me to getting the help I need or to at least calm me down a bit. So is it possible for a person who suffers from severe health anxiety and depression, who is constantly a nervous wreck, stressed out and worried, to have a weaker immune system? Especially if they haven't gotten the help they need or take their prescribed medication? I don't intentionally do this, it just this fear is really making it hard to accept what's in front of me. Also how would it go and weaken the immune system? Like is the nervous system being directly affected or could it be the endocrine system? Maybe both? Thank you in advance! [link] [comments]  |

| How can ice age humans be compared with today humans? Posted: 22 Jan 2020 05:41 AM PST It is common to find pictures of Ice Age humans being depicted as sturdy, grotesque, strong and with long hair and more fur. However, if we consider the ones that lived in 40000bce they did not lived too long ago to have being exposed to evolutionary adaptations compared with today humans. My question is, do humans from the last age were really that different from humans today? Did they had different bodies? Different social structures? What differences they had from us today?

| Posted: 22 Jan 2020 08:46 AM PST I can't find a definite answer from googling it. And I don't have a big enough of a biology vocabulary to understand and peace together an answer from different articles. Would really appreciate it if someone could explain it to me in a dumb down way. [link] [comments]  |
| Differences in DNA replication of eucaryotic and procaryotic cells? Posted: 22 Jan 2020 06:38 AM PST Also- what are the "phases" in the replication? Which enzymes/proteins are a part of the replisome? Could someone explain what chemically happens in the reaction where DNA polymerase catalyzise the creation of a phosphodiester bond between the 3' OH - group and the 5' phosphate group. Is it wrong to say that the 3'OH-group is on the 5' end of the newly created polynucleotide chain? [link] [comments]  |
