| Posted: 23 Apr 2021 07:09 AM PDT Wouldn't features such as craters, rift valleys, and escarpments be eroded away? There are still an abundance of ancient craters visible on the surface despite this, why? [link] [comments]  |
| Build up immunity for allergies? Posted: 23 Apr 2021 01:55 AM PDT So this question just popped up on my head, If you keep getting exposed to something you're allergic to, for example a cat, or peanuts. Would you eventually build up immunity? [link] [comments]  |

| Why are mRNA vaccines cheaper to produce than protein-based vaccines? Posted: 22 Apr 2021 09:59 PM PDT From what I understand, all current COVID vaccines are mRNA based vaccines. My doctor explained to me why these are cheaper than protein-based ones, but I forgot. :( [link] [comments]  |
| What do tumors and cancers actually do thats so deadly? Posted: 22 Apr 2021 06:23 PM PDT What is different from like a cyst growing in the same place? [link] [comments]  |

| Will viruses inactivated with β-Propiolactone set off PCR tests? Posted: 22 Apr 2021 11:57 PM PDT Is there any research that shows whether or not β-Propiolactone inactivation of RNA may still allow PCR tests to detect the particular genetic sequences they're looking for? There is a paper here that discusses four inactivation methods but none of them mention beta-Propiolactone. https://www.sciencedirect.com/science/article/abs/pii/S0168170220302070 [link] [comments]  |
| How does oxygen supply work in a submarine ? Posted: 23 Apr 2021 02:08 AM PDT Missing Indonesian submarine has 72 hours of oxygen left, navy says https://www.bbc.com/news/world-asia-56829278 Do they use oxygen tanks ? How will the release of additional air without a corresponding removal affect the air pressure inside ? How will that affect normal breathing ? [link] [comments]  |

| Posted: 22 Apr 2021 05:51 PM PDT Can you synthesize them in captivity and bring them into the ocean? [link] [comments]  |

| Can a virus or a piece of code be sent to a phone and executed via a phonecall? Posted: 22 Apr 2021 06:39 PM PDT I know that sound during a normal phonecall is made up of zeroes and ones just like any other piece of information. So could you send a file using phonecalls? [link] [comments]  |
| Posted: 22 Apr 2021 06:36 PM PDT I know that spacecraft need to have multiple stage separations because of the vast amount of fuel used to get out of earth's gravity, but when we see what the Apollo astronauts landed on the moon on, it doesn't look big enough to hold much fuel at all. I know the gravity on the moon is much lower but I would have thought they would still need a huge amount. Similarly, in "accurate" films such as The Martian, the spacecraft they leave Mars on are much smaller too. [link] [comments]  |
| How does our body know when to stop producing plasma cells and memory cells after vaccination? Posted: 22 Apr 2021 08:40 PM PDT I keep reading that it takes our body around 2 weeks to ramp up immunity post vaccination but I can't seem to find any info on what makes it stop making the specialized immune cells. Is it just time dependent? Or possibly once some number/threshold has been reached? For example, would somebody with a weaker immune system be able to eventually, given more time, produce just as many immune cells and antibodies as somebody with a stronger immune system? Or is it basically just a race to see how many you can produce within a set time interval (like 2 weeks)? TIA! [link] [comments]  |

| Posted: 22 Apr 2021 12:16 PM PDT I just got finished reading How to avoid a climate disaster by Bill Gates and learned that the reason our climate is heating up is because CO2 being trapped in the atmosphere causes energy from the sun to stay in our atmosphere. But Mars' atmosphere is something like 96% CO2 and the temperature average is around -80° F. Why doesn't energy from the sun get trapped inside the atmosphere of Mars, thus making it hotter?

| Is it theoretically possible to create a universal vaccine against all coronaviruses? Posted: 22 Apr 2021 09:32 AM PDT As the title suggests, will it be scientifically possible someday to have a vaccine that can protect against all forms of coronaviruses and their mutations? Is there an underlying similarity in the viruses that we know about? Or is there enough of a difference that our immune system is forced to react differently to each? [link] [comments]  |
| Posted: 22 Apr 2021 02:07 PM PDT Since SHA 256 is not a 1-1 function, and the domain is larger than the range, wouldn't it be possible to have multiple different inputs to create the same output? If so does this pose a security risk? [link] [comments]  |
