| Posted: 07 Mar 2022 08:40 AM PST Today, we know that it would take infinite energy to achieve a finite speed (with that speed being the speed of light). But before we learned that fact, did physicists believe that if you had infinite energy you could achieve infinite speed? [link] [comments] |

| How does DNA function as an information storage medium? Posted: 07 Mar 2022 08:32 AM PST I wanted to relate this topic to microarrays, but I searched and didn't find much about it. [link] [comments] |
| What makes Cefixime poorly soluble in water? Posted: 07 Mar 2022 07:21 AM PST What structural features of Cefixime molecules make them particularly poorly soluble when administered orally? [link] [comments] |

| Is there a connection between gut bacteria and dreaming? Posted: 07 Mar 2022 04:30 AM PST I almost never remember my dreams. For example if I remember 1 a year it's a big deal. This past month I've been on a super restrictive diet, (trying to lose the COVID kilos). However a couple of times I've had a regular meal and then when I go to sleep I have super vivid dreams that I can remember when I wake up. I am wondering if there is any link between a gut biome and dreaming? As lately my gut bacteria has been cut off from its regular sugars and carbs and processed food that it was used to. And then when having a little bit of it back i have dreamed vividly. (I've been on my restrictive diet for a 5 weeks now and have had 3 cheat meals during this time which have each triggered amazing dreams) [link] [comments] |
| How do winter flowering plants get polinated? Posted: 07 Mar 2022 04:14 AM PST Primroses started blooming in Feb. Crocuses and Camelias started flowering now in March. They all seem to have colourful flowers and a sweet smell which indicates that they are trying to attract flying insects, but there does not seem to be any about (or at least that I can see). How successful are these flowers with insect polination? [link] [comments] |
| Does water evaporate faster if it is mixed with alcohol? Posted: 07 Mar 2022 12:10 AM PST Title is pretty self-explanatory. Was wondering if a mixture of alcohol and water were to evaporate (I am aware that the alcohol will evaporate much faster), but would this have any effect on the evaporation rate of the water itself as well? Reason is because I made a cheesecake and accidentally got the crust soggy. I flipped it upside down and put it back in the oven to try to evaporate as much moisture as possible. Had the idea of putting some everclear in a spray bottle and misting it down a bit to speed up evaporation. Would this hypothetically work? Thanks fellow scientists, I love you all :) [link] [comments] |

| does the location of the centromere change during different stages of mitosis? Posted: 07 Mar 2022 03:39 AM PST If a centromere is said to be a constricted region in a chromosome, does this mean that the location of the centromere does not change during the different stages of mitosis?

| Why can some minerals like quartz have obvious inclusions, but not others? Posted: 06 Mar 2022 07:42 PM PST For example, searching up quartz/amethyst with gold inclusions brings up lots of pictures and selling links, but not for gems like sapphire or emerald, which I think would be quite pretty. Why is that? [link] [comments] |
| Is a or b pinene soluble in fats like melted butter? Posted: 06 Mar 2022 09:08 PM PST It seems like we should have an answer to this but I can't seem to find one. [link] [comments] |

| How long would the process of "Kesslerization" take after the collision that starts it? Posted: 06 Mar 2022 08:33 AM PST I was trying to pitch a C-tier rom-com to a friend that involved *unnamed rich person* being in orbit during the beginnings of the Kessler cascade. My question is, would somebody in orbit have time to deorbit safely after the first couple of collisions make it clear that something like this is going to happen, or would they be toast? I realize that it depends heavily on where the first collisions are and what the density of satellites is like, so let's say we're looking at today's satellites and a first collision wherever a first collision is most likely. All of my attempts to find information about this only told me that once orbit is full of debris it will take 100s/1000s of years to clear up again, which is not what I am looking for.
