| Posted: 28 Jun 2020 02:00 PM PDT Edit: Apparently my phrasing was a little confusing. By one and done I meant "generally" you catch the virus like flu, and it's gone from your body in a couple weeks, as opposed to HIV which lasts your life and is constantly symptomatic. I did not mean that it's impossible to catch the flu again. [link] [comments]  |
| How do chemists dispose of the chemicals they make? Posted: 28 Jun 2020 09:29 PM PDT I always wonder after watching clips where chemists create cool chemicals, and particularly when they make poisonous/dangerous chemicals, how they dispose of it afterwards. [link] [comments]  |
| How exactly do contagious disease's pandemics end? Posted: 29 Jun 2020 06:11 AM PDT What I mean by this is that is it possible for the COVID-19 to be contained before vaccines are approved and administered, or is it impossible to contain it without a vaccine? Because once normal life resumes, wont it start to spread again? [link] [comments]  |
| Posted: 29 Jun 2020 04:31 AM PDT I understand that after 4 years that quarter adds up to a full day which is why we have leap days to set our calendar back on track but if we get an extra almost 6 hours a year wouldn't that mean our clocks would be off by 6 hours every year? So then after 2 years midnight should be off by almost 12 hours, putting it in the middle of the day? But that doesn't happen, I've been searching for an answer for hours but nothing comes up. They just say it adds up to a day after four years but doesn't explain why we don't notice the extra 6 hours per year? [link] [comments]  |

| How does the body know to make antibodies against the other blood types? Posted: 28 Jun 2020 01:37 PM PDT This has been bugging me for a while. I understand that the body will quickly make antibodies to foreign proteins when they enter the body, but there seems to be something very specific about blood type antibodies. Maybe it's because they're easily identified antigens and we're cognizant of them in day to day life. But it seems that, even if your body has never seen the other blood types, the antibodies are there and in strong enough numbers to send you into shock with the wrong blood transfusion. Of course, this is outside of pregnancy when you can be exposed, i.e. rhesus factors. What gives? Are there other antibodies the body creates blindly without a template? Is this template stored somewhere in the body? And is there any evolutionary advantage to this since we weren't exactly giving each other transfusions a thousand years ago? [link] [comments]  |
| Posted: 28 Jun 2020 09:09 PM PDT It seems like the rate of reported neurological effects is pretty low, so is it possible that other coronaviruses could have had the same effects, but the correlation just hadn't been made yet due to less attention being paid to them? Or is it too early to speculate on that yet? [link] [comments]  |
| Can you keep a ''stable'' orbit inside an event horizon? Posted: 28 Jun 2020 11:43 AM PDT Let's say a photon flies into the event horizon, it'll never be able to escape and we cannot ever see or know what's going on in there, but knowing that some event horizons are HUGE there has to be some distance between that and the singularity. So if you're coming in at the speed of light at the perfect angle what happens when the particle ''dips'' inside of the no-return point? As we can't really get information from there do we even have theories, if so what's the most likely? I couldn't really google this well enough as I'm not even sure if the vocabulary I'm using is correct, so I hope someone with the knowledge to either answer or point me to a direction in google sees this. Thanks in advance. Edit: this has taught me a lot, thanks for the great answers! [link] [comments]  |

| Does the frequency of an AC grid change as demand changes? Posted: 28 Jun 2020 12:21 PM PDT As the demand shifts throughout the day, what exactly happens to the AC grid in a large scale power distribution system? In my very limited understanding, I would think that if a sudden large load was applied, the frequency would drop, and the power stations would have to increase the torque on the generators in order to get the frequency back up. Is this correct? How does it all work? [link] [comments]  |
| Is climate change bringing about anything that might be considered beneficial? Posted: 28 Jun 2020 06:03 PM PDT Historians believe the current climate change we are seeing was similar to the climate of the late middle ages. But in that context, it was considered helpful for Europeans as the climate made it easier to grow crops. Are some locations on the planet seeing similar benefits due to climate change?

| Why do some clovers have four leaves? Posted: 28 Jun 2020 03:50 AM PDT Is it genetic – a gene that only manifests under rare circumstances? Or non-genetic – something disturbing the growth pattern? [link] [comments]  |
| Posted: 27 Jun 2020 07:43 PM PDT This post says that scientists estimate that there were only 50 of the Lord Howe Island stick insect in existence in 2006. How would scientists be able to come up with such an estimate? [link] [comments]  |
