| If someone becomes immunized, and you receive their blood, do you then become immunized? Posted: 03 Apr 2018 07:10 PM PDT Say I receive the yellow fever vaccine and have enough time to develop antibodies (Ab) to the antigens there-within. Then later, my friend, who happens to be the exact same blood type, is in a car accident and receives 2 units of my donated blood. Would they then inherit my Ab to defend themselves against yellow fever? Or does their immune system immediately kill off my antibodies? (Or does donated blood have Ab filtered out somehow and I am ignorant of the process?) If they do inherit my antibodies, is this just a temporary effect as they don't have the memory B cells to continue producing the antibodies for themselves? Or do the B cells learn and my friends is super cool and avoided the yellow fever vaccine shortage? [link] [comments]  |
| Posted: 04 Apr 2018 04:00 AM PDT Hello Reddit! I'm Dr. Liz Burmester, an ecologist with the Billion Oyster Project - a nonprofit dedicated to restoring 1 billion oysters in the NY Harbor by 2035 through education and community involvement. Why oysters? As suspension (filter) feeders and reef builders, oysters are a keystone species capable of important ecosystem services like water filtration and habitat creation for a variety of marine creatures. My research revolves around understanding how organisms survive, reproduce, and respond to stress. We use that information to inform the Billion Oyster Project's work on restoring the NY Harbor's - once impressive and thriving, but now functionally extinct - population of oysters. Before transitioning to this urbanized environment, I researched another group of keystone reef builders - corals - and their ability to recover from localized stress. As part of my work, I also serve as a mentor to high school students performing their own independent research in a career and technical education program at the Urban Assembly Harbor School in New York City. Looking forward to your questions - I'll be on at 12 ET (16 UT) - ask me anything! [link] [comments]  |
| How Did We Discover Bi-209 Is Radioactive? Posted: 03 Apr 2018 08:11 AM PDT Given that its half-life is so ridiculously long, what led us to find out that Bismuth isn't actually stable? Did we "get lucky" and happen to witness some decay, or are there analytical ways to determine an element's radioactivity without needing to observe anything? If the latter is the case, what prompted us to do this for bismuth? [link] [comments]  |
| Posted: 04 Apr 2018 08:19 AM PDT I always see documentaries where big constrictors have caught antelopes and are trying to swallow them, but how on earth do they catch them in the first place? [link] [comments]  |
| Why did Homo sapiens become the dominant species on Earth rather than other ancient hominids? Posted: 04 Apr 2018 05:24 AM PDT Do we know what developed in our brain that allowed Homo sapiens to become dominant rather than other ancient hominids such as the Neanderthals who were either absorbed into the gene pool of Homo sapiens or simply died off?

| Posted: 04 Apr 2018 08:06 AM PDT My mother breastfed me while she had chickenpox i didn't get chicken pox and i never have, is it possible that i've already gotten the antibodies? [link] [comments]  |
| Why doesn't the sun look blue? Posted: 04 Apr 2018 07:58 AM PDT I don't understand why the oxygen in the atmosphere makes the sky look blue, but the sun still looks yellow/white. [link] [comments]  |

| How quickly does a SCRAM happen? Posted: 03 Apr 2018 06:55 PM PDT I don't know the situations for when a nuclear reactor needs an immediate shutdown (or how often that comes up) but I do know that once a reactor is packed up with control rods, the next step is to cool the reactor down. How quickly are control rods inserted into the reactor, and does the speed or method vary with reactor configuration? Like, are they just lowered by actuators, do they fall, do they slam down? What is the urgency of a SCRAM? [link] [comments]  |
| Why do our brains wrinkle in order to make more surface area rather than fill out for volume? Posted: 04 Apr 2018 05:12 AM PDT I understand that our brains create these wrinkles to create more surface area, but why is it more important to create more surface area as opposed to volume? I would think that more volume would allow for more cells and therefore more processing power. [link] [comments]  |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 04 Apr 2018 08:07 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science 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]  |
| Can CRISPR repair the genes of someone who is born missing part of a chromosome? Posted: 04 Apr 2018 07:26 AM PDT I was watching this video on r/videos of a woman who was born with Distal 18q- and was wondering if CRISPR could be used in childhood to allow them to develop normally?

| Why do the signs of the cofactors in a matrix alternate? Posted: 04 Apr 2018 06:55 AM PDT We learned in class today that when we're doing determinants using cofactors, the way that you determine the sign of a given term is to start with + or -, then alternate in a sort of checkerboard pattern, like etc. Why is that?

| Has there been a gamma frequency camera invented? If not why? Posted: 03 Apr 2018 03:28 PM PDT I know there are cameras that see in the low light spectrum, IR, and other frequencies than visible light, and I work in radiography using Geiger counters often so I'm wondering why a camera like this hasn't been made in order to keep people from needing to go into gamma radiation in order to test for it? Edit: yeah now I get why it wouldn't make a difference about having to still be in the radiation in order to receive it considering it reflects no light, but now I'm just wondering why none of you in the comments have come up with something that can, you seem like capable minds to me 😅 [link] [comments]  |
| [meteorology] Is "the calm before the storm" a real phenomenon which can be measured? Posted: 03 Apr 2018 06:06 PM PDT I have often wondered if this is just a saying or if it has an actual basis in science. [link] [comments]  |
| How does the Fourier Transform actually 'work'? Posted: 03 Apr 2018 03:41 PM PDT I've covered the Fourier Transform in maths so I know the formula and what it does but its coming up again as part of my chemistry course (2nd year undergrad) when used in NMR and I'm having a hard time trying to figure out how it converts from time space to frequency space. Has anyone got an explanation of how the integral 'picks out' which frequencies are present in the wave? [link] [comments]  |
