| Posted: 09 Jul 2020 10:09 PM PDT And oft-cited figure in the media these days is that around 1% of the general population in the U.S.A. have or have had the virus. But the percentage of tests that come out positive is much greater than 1%. So what gives? [link] [comments]  |
| What’s the relationship between entropy and compressible information? Posted: 10 Jul 2020 04:42 AM PDT I'm trying to remember what I read in a book about information theory. If I recall right, the idea is that if you compare the state of a deck of cards in its original order to a shuffled deck of cards, the first deck has lower entropy (not thermodynamically but in terms of information?) because you can describe the order of the deck in a simpler, more compressed way as compared to the shuffled deck.

| Posted: 09 Jul 2020 09:35 AM PDT I was taught that symptoms of disease (i.e. the seasonal flu) were your body's attempt to kill the disease. How do diseases "die off" in your body if there are no symptoms or medical interventions? [link] [comments]  |
| Do viruses remain in the body forever? Posted: 10 Jul 2020 05:21 AM PDT I was speaking with a coworker who claimed that once a virus enters the body, it is always present in the body from that point onward. I think he was conflating how viruses change the DNA of a cell to make it produce more viruses with the longevity of viruses such as HSV and HIV, but some cursory Internet searches didn't give me a definite answer. Do viruses remain in the body forever, with the immune system simply adapting to their presence? If not, how do chronic viruses such as HSV and HIV remain over years? [link] [comments]  |
| Is it theoretically possible to test for t-cell immunity? Posted: 10 Jul 2020 05:17 AM PDT I have been seeing reports of studies indicating that antibodies for COVID may disappear in a few weeks to months of infection, but that t-cell immunity may remain longer than that. Is t-cell immunity something that we could develop a test for? Is anybody working on that for COVID? [link] [comments]  |
| Is Asthma risk factor for coronavirus? Posted: 10 Jul 2020 04:43 AM PDT Has anyone seen any good research/articles that answer this question? And if it is, how serious of a risk factor is it? How does it compare to others such as diabetes? [link] [comments]  |
| What are the major breakthroughs made in dentistry over the last 20 years? Posted: 09 Jul 2020 11:16 AM PDT As somebody who's currently dreading a visit to the dentist, I'm curious, how has dentistry advanced over the last couple of decades? [link] [comments]  |

| Posted: 09 Jul 2020 09:06 AM PDT I have had this debate a few times both online and in real life and it all seems to hang on just how bad it is that SARS-Cov-2 can be airborne for 16 hours. I am not an expert but with many friends and family in the field of medicine and/or biology it was my perspective that such a revelation means that the virus is much more infectious then we at first believed. Where the problem comes in is that I would think then that even the super-strict lockdowns like in New Zealand should therefore of not been enough to reduce the cases to such an extent which then makes me doubt that the virus is indeed able to hang around for that long. This point is further hammered upon by the other theories of it being mostly asymptomatic and capable of reinfection. So am I overestimating the infectiousness of the virus or (as I have posited) this new theory not as widespread and agreed upon by scientists as the tabloids would have us believe?

| Can rabies be spread through the breathing of infected bats? Posted: 10 Jul 2020 12:34 AM PDT I've read that bats can sometimes carry rabies and can transmit it through bites or saliva that reaches a open wound/mucus. But I'm wondering if rabbid bats breathing can cause the virus to spread in the air and land on your eyes etc? I have found no real answer on the internet at this point. [link] [comments]  |
| How does a vine "know" where to go? Posted: 09 Jul 2020 09:20 AM PDT This morning I woke up to a vine from the neighbors' yard that had reached over 4-5 feet and grabbed on to our clothes line. The vine definitely wasn't there yesterday as we were using the line. Here are pictures: The trippy thing to me is that there is nothing else nearby to really grab on to, but the plant found the clothes line and tied itself around it overnight. How does the vine "know" where to go? Is it just swinging around randomly in hope of connecting to something? How does it "know" when it has grabbed something potentially useful? [link] [comments]  |
| How does photography (both traditional and digital) works? Posted: 09 Jul 2020 07:55 PM PDT I know that early photographers exploited the darkening effects of silver atoms, but I want to know the chemical process behind them. Specifically, how does photons become film pictures? Also, do modern digital cameras use the same technology? Or do they use other methods of capturing and developing light? [link] [comments]  |
| How do sea otters pick up and even break the shell of sea urchins and not feel pain? Posted: 09 Jul 2020 08:17 AM PDT Hey! So I was watching the "our planet" series, and one of the episodes showed a sea otter literally grabbing sea urchins, and bitting them to break their shells. I tried looking up how they did that on the internet but wasn't really helpful 😅🤷🏻♀️ [link] [comments]  |
| Are whirlpools in lakes a real thing? Posted: 09 Jul 2020 05:39 PM PDT I saw the former glee star recently passed away in Lake Piru, CA. There are tweets and petitions going around saying that she was drowned by an underwater whirlpool. I googled it and only found examples of this happening because of tides, etc. Can anyone explain this to me? [link] [comments]  |
| Posted: 09 Jul 2020 06:47 AM PDT Say, if you "catch" it, it hijacks your cells and helps to reproduce some unanimously agreed health benefits. [link] [comments]  |
| Is it possible for plants to develop cancer like mammals? Posted: 09 Jul 2020 06:59 AM PDT |
| Posted: 09 Jul 2020 06:41 PM PDT First of, I don't even know if the HIV stuff is true, I did not see any reliable sources on the net. Second, yeah that's really it. [link] [comments]  |
| Do Pirahnas and Dolphins Cohabitate? Posted: 09 Jul 2020 06:50 AM PDT When I was younger, I remember reading or hearing the statement "if you see dolphins in the water, its safe to swim, since dolphins and pirahnas don't swim together". Is this generally true? I did a little bit of research and it looks like the Amazon's river dolphins are carnivorous and their diet includes pirahnas as well. That obviously means they swim together, but the pirahna packs probably leave when the dolphins come hunting in self preservation, making the statement true. [link] [comments]  |
| How are clinical trial groups decided? Posted: 09 Jul 2020 08:03 AM PDT 100% not politically motivated, just filling gaps in my knowledge. I was reading this study into Hydroxychloriquine released recently - https://www.ijidonline.com/article/S1201-9712(20)30534-8/fulltext It seems promising but in table it lists 2500 or so patients in 4 - 5 groups but the group given the drug alone make up nearly half the participants where as the other half is divided between the other variations. Also the mortality rates are improved with Hydroxy against the 'none' group and seem to be worse with azithromycin, yet the conclusion seems to say the combination is the most effective? Like is say, I'm a complete amateur so some clarification on what I'm missing would be much appreciated. [link] [comments]  |
