- How can new Covid-19 variants be identified so quickly outside the lab, like in an airport holding passengers?
- How were the Great Lakes formed?
- What are the mutations in the Omicron COVID variant, and what is it about these particular mutations that make scientists worried about it?
- When they talk about mutations “escaping” vaccine protection, is it a sliding scale or all-or-nothing?
- Could you theorticly make an modern LCD TV screen that work only in black and white?

- How do they measure the movement of continents ?
- Why is the new COVID variant being called "Omicron" rather than "Nu"?
- How do biologists determine overpopulation of a certain species?
- How does the vaccine distribution work in the human body. I saw some people say something that it stays at the injection site and others say it doesn’t. Don’t all vaccines spread in the body ?

| How were the Great Lakes formed? Posted: 28 Nov 2021 08:54 PM PST This one has been bouncing around my head for a long time. I've lived within an hour of a Great Lake for 20/24yrs of my life, and I still don't understand how they came to be. I've googled it, and all the sites say is "the Great Lakes were formed by the melting of the Laurentide Ice Sheet during the last ice age". I just can't seem to wrap my head around how it all fits together - why is Erie so shallow? Why is Superior so deep? Why the disparity between the two, and how did the melting ice sheet cause it? Thank you in advance, I really apprecite it! [link] [comments] |

| Posted: 28 Nov 2021 09:13 AM PST I kept hearing that this Omicron variant has the potential to escape vaccine protection, and the word escape to me implies completely avoid it. Is that what escape means in this context, or does escape mean that it reduces but doesn't nullify the protection of vaccines?/r/ [link] [comments] |
| Could you theorticly make an modern LCD TV screen that work only in black and white? Posted: 29 Nov 2021 03:02 AM PST For everyone wondering, I'm writing a story and I want it to be possiable in universe to buy a b/w TV set in modern times, but I still want to make it realistic in the terms of science, so I need to choose if they simply still make CRT TVs, or just have a b/w LCD screen option, so, is a b/w LCD TV could be a thing?

| Why do COVID-19 variants mutate in immunocompromised individuals? Posted: 28 Nov 2021 04:36 PM PST If Omicron likely came from one immunocompromised individual, what did that person's immune system have to do with how the variant could mutate? [link] [comments] |
| How do they measure the movement of continents ? Posted: 28 Nov 2021 08:36 PM PST |
| Why is the new COVID variant being called "Omicron" rather than "Nu"? Posted: 27 Nov 2021 03:09 AM PST If they follow the Greek alphabet then the new one should be called "Nu". So why did they skip not one, but two letters to "Omicron"? [link] [comments] |
| How do biologists determine overpopulation of a certain species? Posted: 28 Nov 2021 10:43 AM PST I was just reading about the overpopulation of sea urchins on the U.S. pacific coast. I began wondering how scientists actually deem if a population is officially dangerous to its ecosystem. Are there certain factors that go in to determining an overpopulation threshold? How do biologists decide if an ecosystem is out of balance due to one or more populations' growth? [link] [comments] |
| Posted: 28 Nov 2021 12:01 AM PST I'd really appreciate some articles/studies showing how distribution works to better understand. [link] [comments] |
| Can annual plants become perennial in controlled environments? Posted: 27 Nov 2021 09:22 AM PST If I take my marigolds inside for the winter to protect them from the elements, will they continue to flourish or are they genetically 'programmed' to die after one growing season regardless of the weather? [link] [comments] |
| Are there documented COVID-19 cases linked to surface-to-patient transmission? Posted: 27 Nov 2021 11:23 PM PST Either way, why do many places seem to emphasize surface sanitization and hand washing as opposed to ventilation? [link] [comments] |

| Can you apply the principles behind dendrochronology to estimate the age of a carrot? Posted: 27 Nov 2021 08:10 AM PST Crazy post, I'll admit. My carrot has rings when I cut a cross section. Can I determine its age? I suppose it's age in growing days? [link] [comments] |
| Why were the retro rocket packs on the Mercury capsules painted with silver and black stripes? Posted: 27 Nov 2021 09:53 PM PST For years I thought the stripes were structural ribbing, but I've never been able to find any photos other than simple painted on stripe on the Mercury spacecraft. Why is that? [link] [comments] |
| Posted: 27 Nov 2021 02:00 PM PST I'm sure this part is old turf, but one of the things that makes Covid-19 so devastating is the combination between incubation period, non-symptomatic spread, and severity of symptoms. I remember doing a lot of reading about the Covid Incubations and asymptomatic as we were learning more but I'm wondering if there is historical data or recent studies on the less dangerous coronaviruses and rhinoviruses to see if Covid-19 is novel on those fronts?

| What is oobleck and what does it mean for something to be non-newtonian? Posted: 27 Nov 2021 07:43 PM PST I keep on reading that it is a "non-newtonian" solid. What does non-newtonian mean exactly and how can we say that it is not liquid? Why does applying pressure to the corn starch and water mixture cause the liquid to harden? How is this able to act as it does on a molecular level? Sorry that my questions are all jumbled up. This thing is so bizzare to me. [link] [comments] |
| How come endometriosis is not treated like cancer? Posted: 27 Nov 2021 07:14 AM PST This disease occurs when the endometrial-type tissue grows outside of the uterus and implants itself into other organs such as bowels. Edit: I see there are 10 comments but I don't know why I can't open and read them. [link] [comments] |

| Why does infection cause increased blood sugar in diabetics? Posted: 27 Nov 2021 09:44 AM PST I'm a type 1 diabetic and have been lucky enough to be very healthy, I recently had a pretty bad infection and the first thing I noticed was my blood sugar became near unmanageable. Why is this? [link] [comments] |
| How many Sol-like systems are out there/do we know of? Posted: 27 Nov 2021 06:15 PM PST The Copernican principle says that we shouldn't consider our position in the Universe extraordinary or peculiar in any particular regard. But I only ever hear about extrasolar systems with 'hot jupiters', planets with higly eccentric orbits, and so on. The Trappist system is similar, but everything is super-close in. Do we expect other Sol-like systems out there and we just haven't found them, or are we just somehow lucky? [link] [comments] |
| Do we need new Covid tests kits for every strand of mutations? Posted: 27 Nov 2021 05:49 AM PST How do rapid lateral flow tests detect Covid? Are they targeting a specific strain/mutation? Do we need to changes the tests kits for every mutation? [link] [comments] |
