| Does warmer weather curb the spread of COVID-19, somewhat? Posted: 06 Jun 2021 02:42 AM PDT To my current understanding, it seems like COVID-19 spread was curbed somewhat during the summer of 2020. Although, with the second wave hitting India, killing thousands. It got some second thoughts. Looking at Europe, our COVID-19 spread was somewhat stopped, could it be because large portions of society were coming out of lockdown? Can variants be more "resistant" to hot weather? Also, if hypothetically speaking, weather curbs the spread of COVID-19, would a lockdown during hotter months be a viable solution? [link] [comments]  |
| Is there a reason for the difference between flu and covid vaccine effectiveness? Posted: 06 Jun 2021 06:31 AM PDT From what I've read, the latest research seems to be suggesting that all of the 2-shot covid vaccines are likely to be around 90% effective - or even better - against symptomatic disease by a couple of weeks after the second shot, whereas flu vaccines sound like they're typically closer to 50% effective. Firstly, am I understanding the figures correctly? And if I am, is there a reason for the the difference? How much is down to the fact that it's two shots rather than one (the AZ one at least sounds like the first shot is closer to a typical flu vaccine in terms of effectiveness). Or is there some other reason for it? [link] [comments]  |
| Do antibodies make a difference if a person has a low immune system? Posted: 05 Jun 2021 08:17 PM PDT If you have antibodies to a virus, but your immunity is low the day or time you come into contact with it, will your body be able to fight it properly? Will it be extremely less effective? And one extra question, how much immunity lowers when a person skips a day of sleep? [link] [comments]  |

| Posted: 04 Jun 2021 06:52 PM PDT I'm assuming here that it's a mutation that causes a new species to appear and that there would be so few numbers of them that would get that mutation so the next generations would end up being inbred, feel free to tell me if that assumption is completely wrong though lol [link] [comments]  |
| Posted: 05 Jun 2021 01:16 AM PDT If same change's repel each other, why don't free charge's concentrated in a point of a conductor repel each other strongly enough to make them spread out ? [link] [comments]  |
| Why does atoms want to be sp3 hybridized? Posted: 04 Jun 2021 09:34 PM PDT I was watching a recorded orgo lecture, the professor mentioned the BCl3 has an sp2 orbital and can accept a pair of electrons, which makes it a Lewis acid. Why does it want to gain an electron pair and make itself sp3 hybridized? Is sp3 more stable? And if so why is it more stable? Does that mean every carbon in a double bond with another double bond would rather try to break that double bond and form another sigma bond in order to become sp3 hybridized? [link] [comments]  |
