- AskScience AMA Series: We are Tabitha Lipkin and Liv Williamson a Naui Dive Master and NBCLX host and a marine biologist respectively. Ask us anything!
- Can the KT boundary be found at the Appalachian mountains?
- Are there chess problems that we can’t solve, similar to there being math problems we can’t (currently) solve?
- Would a single photon be bright enough to be visible to the human eye if it was the only source of light in a pitch-black room?
- Physics question, if stars moving away/towards Earth appear blue/red shifted, how do we know their colours are red/blue because they are moving, and not just that they are a red/blue coloured star that’s relatively stationary?
- Does COVID viruses stay dormant in your body after you recover?
- If a person was in a spaceship near Jupiter, would it be bright like the moon at night? Or darker? Photos of Jupiter always look bright, is that just a really high ISO setting on said cameras?
- Why doesn't all of the carbon dioxide in carbonated drinks come out immediately?
- Is there a theoretical maximum size of a rocky planet?
- How do construction workers determine which type of charge they will use to destroy a structure?
- Does the amount of salt in water effect the time it takes to evaporate?
- How does frequent exposure affect immune response?
- How does Raynaud's Syndrome work? Why does it cause my fingers (and occasionally toes) to go white?
- How does Plasmapheresis work?
- Is there a "speed limit" to a moving flame before it extinguishes itself?
- How does the presynaptic terminal stays at the postsynaptic neuron?
- how does hawking radiation exist?
- Since a star's light takes so long to reach us, how do we know that the star is still there?
- How would a longer day/night cycle affect a person’s circadian rhythm?
- Ignoring time zones (let's consider north/south only for a second), is the average sunrise the same globally?
- How do satellites not get affected by the moon's gravity and fly away?
- If you had a human liver would you be able to tell if it came from a man or a woman, other than by examining its' DNA?
| Posted: 03 May 2021 04:00 AM PDT We partnered to teach you all about how to restore coral reefs and save our oceans. Liv is a Ph.D. candidate and scientific SCUBA diver at the University of Miami with a passion for coral reef conservation. She loves baby corals, and runs a sort of "fertility clinic" to help corals reproduce and raise their offspring to be fit to survive under environmental stress. Tabitha has been scuba diving for more than 10 years on reefs all over the world. In 2014 she won "Miss Scuba International", and with the title and platform, she's continued to share her passion for ocean conservation and activism around the world. We'll be here at 1pm ET (17 UT), ask us anything! Username: /u/NBCLX [link] [comments]  |
| Can the KT boundary be found at the Appalachian mountains? Posted: 03 May 2021 06:20 AM PDT I've been reading a bit about the KT boundary and it being a layer of clay 65 million years old at the time when the dinosaurs went extinct. Also, this weekend I crossed the Appalachians and noticed the wonderful layers apparent there so I tried to figure if the KT boundary could be seen there. My first thought is no, because the Appalachians are really really old, Pangea old as far as I read; and the more recent layers have been sheared off by the ice age. So I would asume the KT layer went with it. Is this correct? Or can the KT layer be seen there? Obviously I'd imagine that one would need proper training to identify it, but my question is: is it present there for experts to identify? Thanks! [link] [comments]  |

| Does COVID viruses stay dormant in your body after you recover? Posted: 02 May 2021 11:39 PM PDT Hi all, just wondering can COVID viruses stay dormant in your body even after you have recovered from it? I know cold sores & chickenpox can stay in the body for long periods of time without being activated, and I was wondering since all of these are all categorized as a viral infection, could this apply to COVID as well? Thanks in advance guys, genuinely curious about this. [link] [comments]  |
| Posted: 02 May 2021 07:00 AM PDT I've seen a number of photos and videos of the outer planets recently, and having a vague idea of how the inverse square law works regarding light emission, it seems logical that Jupiter should be kinda dim. Am I missing something? Because obviously you can see Jupiter on a clear night, so are these probe cameras just using similar settings to on-earth cameras? [link] [comments]  |

| How do construction workers determine which type of charge they will use to destroy a structure? Posted: 02 May 2021 07:31 AM PDT When removing a building, how do engineers figure out how to remove a building safely? Once they decide to blow it up, how do they determine which type of charge (I hope this is the correct term) to use? When I say charge, I mean what factors determine the relay series that will detonate the bomb. [link] [comments]  |
| Does the amount of salt in water effect the time it takes to evaporate? Posted: 02 May 2021 07:45 AM PDT like, does more salt make water take longer to evaporate? [link] [comments]  |
| How does frequent exposure affect immune response? Posted: 02 May 2021 07:57 AM PDT Is the relationship between COVID immunity and repeated exposure known? For example, if one already has antibodies thru vaccination or prior infection, would they produce more antibodies/strengthen immune response with repeated exposure to COVID over time? Basically does the immune response generally strengthen or weaken over time given presumably frequent exposure? [link] [comments]  |
| How does Raynaud's Syndrome work? Why does it cause my fingers (and occasionally toes) to go white? Posted: 02 May 2021 05:13 AM PDT |
| Posted: 02 May 2021 07:44 AM PDT There was this girl who had PANS and she had this treatment, Plasmapheresis. As I know, PANS happens because immune system attacks neurons and a chemical unbalance in brain occurs but what is it to do with blood? Another thing that I wonder is how this sickness has kind of same symptoms as OCD? [link] [comments]  |
| Is there a "speed limit" to a moving flame before it extinguishes itself? Posted: 02 May 2021 08:46 AM PDT |
| How does the presynaptic terminal stays at the postsynaptic neuron? Posted: 02 May 2021 03:44 AM PDT I wondered about this because the two neurons never actually touch. The synaptic cleft is very small, but if there is no connection the neurons might easily separate... [in chemical synapses] [link] [comments]  |
| how does hawking radiation exist? Posted: 02 May 2021 06:27 AM PDT
(i only have a laymans understanding so i may have made a very silly mistake) [link] [comments]  |
| Since a star's light takes so long to reach us, how do we know that the star is still there? Posted: 02 May 2021 08:51 AM PDT |
| How would a longer day/night cycle affect a person’s circadian rhythm? Posted: 02 May 2021 12:13 AM PDT If you were to go to another planet with a longer day cycle for an extended period of time, would your body be able to permanently adjust to that? If so, to what degree? On Mars, a day lasts 24hrs 36min, so you could probably adjust to that, but what about something like 30 or even 48 hours? [link] [comments]  |
| Posted: 02 May 2021 01:30 AM PDT Around the equator the sunrise is the same every day, around 6am. Going further north that fluctuates further. However, does the average sunrise remain am globally? To add to that, if timezones were correct for their area, would that also be the same globally? [link] [comments]  |
| How do satellites not get affected by the moon's gravity and fly away? Posted: 01 May 2021 11:42 PM PDT Considering that satellites are somewhere between the earth and moon, shouldn't the moon pull sattelites a little farther away from earth every time it passes by? I would believe that since it's flying just high enough that it's speed is enough to not fall down to earth, a body like the moon flying by could potentially change it's orbit a bit, enough to pull it out of earth's orbit or at least force it to adjust it's route a bit, but it seems like there are 60 years+ old satellites still up there.
