| Can blood transfusions grant someone immunity to a virus that they previously had no exposure to? Posted: 08 Jul 2020 06:21 AM PDT If the donor already has antibodies to deal with a certain virus and the recipient didn't already have those antibodies developed, would the transfusion give the recipient the ability to make their own antibodies without exposure to the virus?

| How does the immune system already have the DNA to make antibodies for new viruses? Posted: 08 Jul 2020 02:36 AM PDT So I get exposed to a newly evolved virus, and my body will eventually "learn" to make a protein to combat it. How? Does that genetic code already exist in my DNA and my body is just turning it on or do my cells edit DNA to make a specially designed antibody? If it's the former, what happens if a virus evolves that doesn't match any DNA code I have for antibodies? Or is that not going to happen because they are using antigens that have to match my cell's proteins? If it's the latter, doesn't that go against the "central dogma" of DNA that info only flows in one direction? (DNA --> Protein) [link] [comments]  |

| Posted: 08 Jul 2020 12:56 AM PDT I have seen and read that the speed of light isn't really so much the speed of light, it is the speed of any massless particle as well as the maximum speed that information and causality can travel, the maximum speed that a phenomenon can reach and affect another point in space. Light however has different speeds when going through different mediums. Does that mean that the speed of causality also changes in different mediums or is the speed of causality the same in the vacuum as well as through glass for example? [link] [comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 08 Jul 2020 08:08 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| Why do neutrinos pass through objects but light can't? Posted: 08 Jul 2020 07:23 AM PDT I watched a video that mentioned how neutrinos from a supernova explosion reached earth before the star even exploded. And they mentioned that neutrinos way close to nothing 1,000,000 times lighter than electrons even. Does that have anything to do with the fact that neutrinos hardly interact with matter? If so, shouldn't light also not interact with objects since it is massless? [link] [comments]  |
| Some primitive Australian and African tribes use a binary system to count. How does that work? Posted: 08 Jul 2020 03:29 AM PDT I was reading "understanding media" by Marshall McLuhan the other day and he mentions the following in his book: "The most primitive tribes of Australia and Africa, like the Eskimos today, have not yet reached finger-counting, nor do they have numbers in series. Instead they have a binary system of independent numbers for *one* and *two*, with composite numbers up to *six*. After *six*, they perceive only "heap"." How does a system like this work when you need basic numbers in pretty much every aspect of life? [link] [comments]  |
| Posted: 07 Jul 2020 12:10 PM PDT Recently, I've seen a few posts and articles pop up saying that the virus is airborne and that it lingers for a while. But isn't it known that in droplet infections, the minute droplets linger around for a bit before settling down? Haven't we already been treating it as such? [link] [comments]  |
| How did multicellular life appear? Posted: 07 Jul 2020 06:23 PM PDT |
| Are bats recovering from White Nose Syndrome? Posted: 07 Jul 2020 06:10 PM PDT I live in Pennsylvania where WNS decimated the bat population. Lately I have been seeing more bats around and I am wondering if a recovery is taking place. I have not heard about the disease in a few years and have seen no new information about the topic.

| Posted: 07 Jul 2020 07:19 PM PDT Asking because I was kind of thinking about it and how it would be impractical to send a probe given it would take at least like 1500 years to receive data [link] [comments]  |
| How are some drugs capable of entering the blood stream through the mouth? Posted: 07 Jul 2020 03:29 PM PDT Drugs like immodium have variations that allow them to enter the blood stream through the mouth, and therefore faster. Why do some drugs, like painkillers, not have this? [link] [comments]  |
| Posted: 07 Jul 2020 04:08 PM PDT WRT possible safety, one precedent is that many older people have received two different Shingles vaccines (the newer vaccine is said to be more effective). With Operation Warp Speed, multiple vaccines are planned to go into production before testing is completed. [link] [comments]  |
| Are we able to identify different types of self-antigens? Posted: 07 Jul 2020 07:39 PM PDT For example, in type 1 diabetes (autoimmune disease) the CD4 and CD8 T cells identify the beta islet cells as foreign but not any of the other islet cells. Does the beta islet cell have a specific self-antigen than other islet cells? [link] [comments]  |
| When a disease is eradicated does the pathogen get wiped off the earth? Posted: 07 Jul 2020 11:03 AM PDT I have a few questions about disease eradication and what it actually means --

| If we cannot improve our immune systems, are the genetically predetermined? Posted: 07 Jul 2020 02:42 PM PDT After seeing lots of articles about foods to eat to boost immune system, I read one article that said you actually can't do anything. Does that mean our own immunity is similar to other aspects about ourselves we can't change, and why is there so much information out there that suggests we can change it by what we eat?

| Posted: 07 Jul 2020 09:05 AM PDT Can vinegar get moldy over time? i.e. If I opened a bottle of commercial distilled vinegar and left it out unrefrigerated at what point would mold accumulate, if ever? [link] [comments]  |
