| When did pee and poo got separated? Posted: 25 Apr 2020 05:43 AM PDT Pee and poo come out from different holes to us, but this is not the case for birds! When did this separation occurred in paleontology? Which are the first animals to feature a separation of pee vs. poo? Did the first mammals already feature that? Can you think of a evolutionary mechanism that made that feature worth it? [link] [comments]  |
| Can a severed muscle be put back together? Posted: 24 Apr 2020 06:50 PM PDT It might sound odd, but my brain comes up with weird hypotheticals I desperately want the answers to. I tried to google this, but it didn't give the exact answer I wanted. If a skeletal muscle is completely severed for some reason, as in it is now two seperate pieces, can those pieces be reattached somehow? If so, would that also work if a piece from the middle was removed and you tried putting the remaining ends together? (Ignoring mobility difficulties from shorter muscle length, I just want to know if it's physically possible). [link] [comments]  |

| When doing human trials for a vaccine, how do scientists know if it’s working? Posted: 24 Apr 2020 10:47 AM PDT I realize that part of the human trials are to ensure that there are no serious or long term side effects. In terms of ensuring the vaccine prevents people from getting sick, will scientists inject people who haven't yet gotten sick yet and then put them in an environment to get sick and just hope that they don't? Or is it just a case of seeing if their body develops the anti bodies and calling it a day if they do? [link] [comments]  |
| Can other planets see Earth during the day? Posted: 24 Apr 2020 05:04 PM PDT I was looking at other planets last night and was thinking about how they're so bright, that what we see must be 'daytime' on each planet. From the perspective of say mars at night time, would you be able to see earth in the same sort of way? (I'm sure I could've phrased it better) [link] [comments]  |

| How has the reduced “background noise” from reduced machinery and transport affected seismology? Posted: 24 Apr 2020 07:37 AM PDT My country has reported that seismological devices have shown reduced "noise" during our lockdown and that they are led to believe more and more people are disregarding the stay at home order because it has picked back up. I'm wondering if measurements made now are more accurate/ precise. Can we look further into the earths crust or predict volcanic/seismic activity better now that our devices can pick up smaller activity? Or is this a negligible difference when it comes to making measurements of the earths crust/mantle/core etc? Are there any cool experiments you think should be carried out whilst we have some peace and quiet? [link] [comments]  |
| Posted: 24 Apr 2020 09:42 AM PDT So in the Netherlands now they are studying whether they can use mother milk with the antibodies for the virus for elderly to ingest to then be immune to the virus. However, I know that for piglets and calves that the intestine can only absorb the antibodies from the colostrum for only a few hours, but is this the same in humans or can we still absorb antibodies at later age?

| How do logic gates actually 'decide' on it's output based on its input? Posted: 24 Apr 2020 10:51 AM PDT Does it work like an election switch or something mechanical? And how are they engineered to the given output when they are so small? The logic gates are so small and I'm not sure how logic gates work physically. I understand the theory behind it but practically speaking? Thanks [link] [comments]  |
