| Posted: 18 Oct 2020 03:58 AM PDT For example, when it is recommended that people wash their hands regularly, wear a face covering and stay 2 metres apart, how can we tell which of the measures is having the biggest impact in order to further our understanding of how the virus spreads, when there is not a control group to compare?

| Following COVID-19 protocols, why can I get a cold or flu? Posted: 17 Oct 2020 03:06 PM PDT I follow COVID-19 protocols (mask, handwashing, distancing, wiping down any packaging/food/mail). Why am I still vulnerable to getting a cold or the flu? [link] [comments]  |
| Could remdesivir decrease severity of symptoms without decreasing mortality? Posted: 17 Oct 2020 01:39 PM PDT For example, the use of inhaled nitric oxide does not decrease mortality, but by increasing oxygenation will allow for less hypoxic episodes leading to less damage. Having less hypoxic episodes also allows for gentler mechanical ventilator settings, meaning less damage to the lungs. Could remdesivir have a similar effect? [link] [comments]  |

| Does brushing your teeth select for more adherent bacteria? Posted: 17 Oct 2020 02:30 AM PDT As I understand it, when you brush your teeth you are physically removing bacteria by force. Why aren't you therefore selecting for more adherent bacterial cell types, thus making it so that efficiently removing bacteria by brushing becomes more and more difficult over many years? Is this something that can/does occur or is the sheer force of removal by brushing simply too much for the cells to adapt against/cope with? Someone asked me this during a conversation regarding bacterial resistance against antibiotics and I honestly am not sure how to address it. Cheers for any helpful answers. [link] [comments]  |
| Posted: 17 Oct 2020 07:47 AM PDT I have several friends and family who are avid hunters and several of them use these expensive GPS tracking watches so that we can monitor their location in semi real time (updated every hour or so). I was wondering what method of communication these watches had to transmit that data so reliably even when they're deep in the woods, up on top of mountains, or down in valleys. [link] [comments]  |
| What are importines are exportines ? Posted: 17 Oct 2020 08:48 AM PDT I'm studying the nucleus cytoplasm transport in celular biology, and I don't quite get wether the importines and exportines are the proteins that join NLS or NES to then join the exportation or importation receptor directly or with an adaptador to create a complex that goes through the pores from or to the nucleus, or if the importines and exportines are the importation or exportation receptors themselves. I know beta importines are receptors so I'm turning a little crazy. Help please !!! [link] [comments]  |
| Can someone explain how long term memories are stored in the brain? Posted: 17 Oct 2020 08:56 AM PDT Is it a fully structural thing? Does that mean the structures are rewritten if you think about them in different ways enough? [link] [comments]  |
| Why hasnt all water on earth turned into tea? Posted: 16 Oct 2020 07:07 PM PDT Hear me out! I'm not trying to be ridiculous, but trees and plants have been around for 350 million years. Plant leaves in water make tea, how has 350 millions years of plants annually dropping their leaves not turned at least all fresh water lakes and ponds into huge tea pots? Do fish really filter that much water, and if so are they essentially the biggest consumers of tea on the planet? [link] [comments]  |
| How come you can't see space debris in the earth pictures? Posted: 17 Oct 2020 06:17 AM PDT How come if we see the pictures of the beautiful earth from space or ISS we never see the debris that flies around the earth although there are thousands pieces of debris that constantly colliding with one another [link] [comments]  |
