| How effective is the JJ vaxx against hospitalization from the Delta variant? Posted: 23 Jun 2021 04:12 AM PDT I cannot find any reputable texts stating statistics about specifically the chances of Hospitalization & Death if you're inoculated with the JJ vaccine and you catch the Delta variant of Cov19. If anyone could jump in, that'll be great. Thank you. [link] [comments]  |

| Posted: 23 Jun 2021 07:22 AM PDT All studies of mixing viral vector and mRNA vaccines were done with AstraZeneca and Pfizer. Is it scientifically rigorous to infer that any mRNA vaccine can be mixed based on these studies? [link] [comments]  |
| What will happen if I get infected by COVID-19 a few minutes before getting vaccinated? Posted: 23 Jun 2021 09:19 AM PDT In my country, the queue for COVID-19 vaccinations tends to be long and people in line do not follow safe distancing measures. What will happen if I get infected with COVID-19 while queueing for the COVID-19 vaccine then get vaccinated a few minutes or some hours after? Will the vaccine still protect me? [link] [comments]  |
| How long until I can eat the raspberries along a used engine oil soaked driveway? Posted: 23 Jun 2021 10:31 AM PDT My raspberries run the length of our driveway and my husband opted to blacken the driveway by spreading used diesel engine oil on it. He absorbed everything still wet with grass clippings and sawdust. I cleaned that up and I've been out there with Dawn and a pressure washer spraying AWAY from the plants, but plenty of that water has made it into the soil and every time it rains or I water, a little more will run in. Any idea how many years until I can eat my raspberries again? What about all the ones that are forming now? They are about half their final size. Is there any chance I can move enough away that I can eat my raspberries? I can't find much science online about this. Help please. [link] [comments]  |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 23 Jun 2021 07:00 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.

| Posted: 23 Jun 2021 07:17 AM PDT I am thinking that ancient civilisations must have known some kind of rock formation to be able to build such mega structures. Is it possible that Stonehenge could have been made from some sort of concrete ? I mean rock is the first tool human used, thousands of years must have teach us some techniques. [link] [comments]  |

| What's the main barrier to creating an HIV vaccine? Posted: 22 Jun 2021 03:15 PM PDT Is it that the virus mutates too quickly? Is the virus too complex/have antigenic surfaces that wouldn't produce effective antibodies? Would it be a good candidate for mRNA vaccine technology/is there a highly conserved protein on it that would work? [link] [comments]  |
| Why do we get wave after wave with Covid infections? Posted: 23 Jun 2021 07:08 AM PDT Why does Covid come in waves? After we got surprised by Covid initially, we got it down to a manageable infection rate. But then, it went up again. TWICE more. Why do we not manage to keep it down until sufficient vaccinations have been done and we're in the green? Or is it just negligence of our fellow citizens who get careless when the infection rates are down? [link] [comments]  |
| Can artificial endocytosis be created? Posted: 23 Jun 2021 05:53 AM PDT I saw this image online. https://imgur.com/gallery/u3YRi0a Do antibodies on a material wrap around a virus like this? I know endocytosis is said to be triggered. However, can materials fold inwards like the cell membrane does if there's many antibodies and receptors? [link] [comments]  |
| Why is esophagoscopy contraindicated in heart, liver and kidney diseases? Posted: 22 Jun 2021 11:19 PM PDT |
| Can we make a vaccine for plants? Posted: 22 Jun 2021 05:14 PM PDT Plants can get infected with viruses too. (Mosaic is an example) can we vaccinate plants against that? Would the plant cells be able to memorize the pathogen and fight it off after being vaccinated? How different would it be from human/animal vaccines? [link] [comments]  |
| How did researchers come up with SHA-2? Posted: 23 Jun 2021 04:13 AM PDT Looking at the steps-by-steps of the algorithm (wikipedia or https://qvault.io/cryptography/how-sha-2-works-step-by-step-sha-256/), how did the (NSA?) researchers come up with this algorithm? I've read from https://crypto.stackexchange.com/questions/41923/why-are-cube-and-square-roots-of-primes-used-as-sha-constants that the initial constants are https://en.wikipedia.org/wiki/Nothing-up-my-sleeve_number and that makes sense to me, but what about the other constants like 2, 3, 7, 10, 15, 16 in the bit rotations of the chunks? Why are there 64 iterations of the compression function? Why not 32 or 96 or 37? How did they choose the xor/rotations/sum/invert combinations? My theory (could be 100% off-track) is that they had goals for the function, like pseudo-uniformly distributed output and efficiency, then basically tried random combinations of operations until they hit metrics? Any insight or simple guides on the design of cryptographic hash functions appreciated. [link] [comments]  |
| Is the Alpha variant more virulent than the previous variants? Posted: 23 Jun 2021 05:08 AM PDT I remember reports that claimed that Alpha variant was like ~50% more virulent/aggressive than previous variants, resulting in more hospitalizations and/or more deaths in hospitalized patients. While now I read claims of Delta variant being more virulent resulting in more hospitalizations, I also happen to read that Alpha variant was not more aggressive than previous variants, and I'm a bit confused about what's the scientific consensus about this. It should finally be confirmed whether it is or not, so what's it? [link] [comments]  |
| [BIOLOGY][COMPUTING] Experimental Research Prior to the Usage of Computational Methods? Posted: 22 Jun 2021 11:23 PM PDT It's my understanding that the ideas and frameworks to utilize computers and computational methods to study biological data (e.g. sequence data), were laid out in the 1960s. These ideas and frameworks would develop into the fields of bioinformatics, computational biology and HPC. However, they were not routinely used in experimentation until the 1990s and 2000s, during the Human Genome Project, largely because the computational power needed to do such analysis was not available. So, my question is, prior to these fields' integration into experimental research, how did scientists go about, for example, discovering new drugs or identifying targets (say on a cell or pathogen) for therapeutics and generally making developments, many of which nowadays are first theorized with computational models and then tested in a lab? Let me give an example that might clarify my question. PyMOL and GROMACS are molecular dynamics (MD) software that run on supercomputers and help us to visualize molecules and observe how atoms in a molecule interact with other molecules. For example, we use MD to study how the HIV virus enters cells. However, these tools didn't exist until the 21st century and 1991, respectively. So, how would a scientist have gone about understanding how HIV enters cells before this technology existed? Would they have just tried brute force trial and error experimentation in the lab to see which receptors HIV would bind to? Or was there some systematic and resource-efficient way they could have theorized this and then tested it out in the lab? TLDR: How did scientists discover drugs, identify critical receptors in a biochemical pathway, or do molecular modeling before bioinformatics, computational biology, and high performance computing existed (which could have helped them theorize and then test)? Did they just do trial and error experimentation in a wet lab and consume resources inefficiently? [link] [comments]  |
| What causes frequency to drop when load is increased on an AC generator? Posted: 22 Jun 2021 06:00 PM PDT I know that this happens but I have no idea why or how to prove it using equations. [link] [comments]  |
