| Posted: 28 Apr 2021 11:15 AM PDT I really tried to google this, but I didn't see clear explanations on the difference. If I google RBG then I find posts which call these the primary additive colors, with green and red making yellow. I thought maybe my primary schooling was just old and color theory had changed a bit, but if I google primary colors for art purposes like painting, then it seems that blue, red and yellow are still the primaries for, say, mixing paints.

| AskScience AMA Series: We're climate scientists from around the world. Ask us anything! Posted: 29 Apr 2021 04:00 AM PDT Hi Reddit, We're the six scientists profiled in the Reuters Hot List series, a project ranking and profiling the world's top climate scientists. We'll be around for the next several hours to answer your questions about climate change and more. A little more about us: Michael Oppenheimer, Professor of Geosciences and International Affairs at Princeton University: My research and teaching focus on climate change and its impacts, especially sea level rise and human migration. My research group examines how households and societies manage the impacts of sea level rise and coastal storms, the increasing risk these bring as Earth warms, and policies to reduce greenhouse gas emissions, increase adaptation and limit the risks. We also model the effect of climate change on human migration which is a longstanding adaptation to climate variations. We project future climate-driven migration and analyze policies that can ease the burden on migrants and their origin and destination communities. Follow me on Twitter. Corinne Le Quéré, Royal Society Professor of Climate Change Science at the University of East Anglia in the UK: I conduct research on the interactions between climate change (ePDF) and the carbon cycle, including the drivers of CO2 emissions (ePDF) and the response of the natural carbon sinks. I Chair the French High council on climate and sit on the UK Climate Change Committee, two independent advisory boards that help guide climate actions in their respective governments. I am author of three IPCC reports, former director of the Tyndall Centre for Climate Change Research and of the annual update of the global carbon budget by the Global Carbon Project. Read more on my website, watch my TED talk and BBC interview, and follow me on Twitter. Ken Caldeira, Senior Scientist at Breakthough Energy: I joined Breakthrough Energy (BE) as Senior Scientist in January of 2021, but I have been helping to bring information and expertise to Bill Gates since 2007. I'm committed to helping scale the technologies we need to achieve a path to net zero emissions by 2050, and thinking through the process of getting these technologies deployed around the world in ways that can both improve people's lives and protect the environment. Visit my lab page and follow my blog. Carlos Duarte, Distinguished Professor and Tarek Ahmed Juffali Research Chair in Red Sea Ecology at the King Abdullah University of Science and Technology (KAUST), in Saudi Arabia: My research focuses on understanding the effects of climate change in marine ecosystems and developing ocean-based solutions to global challenges, including climate change, and develop evidence-based strategies to rebuild the abundance of marine life by 2050. Follow me on Twitter. Julie Arblaster: I'm a climate scientist with expertise in using climate models to understand mechanisms of recent and future climate change. Kaveh Madani, Visiting Scholar (Yale University) and Visiting Professor (Imperial College London): My work focuses on mathematical modeling of complex, coupled human-environment systems to advise policy makers. Follow me on Twitter, Instagram, Facebook and YouTube. Watch my talks and interviews. We're also joined by Maurice Tamman, who reported "The Hot List" series and can answer questions about how it came together. He is a reporter and editor on the Reuters enterprise unit based in New York City. His other work includes "Ocean Shock," an expansive examination of how climate change is causing chaos for fisheries around the planet. Previously, Mo ran the unit's forensic data team, which he created after joining Reuters in 2011 from The Wall Street Journal. We'll be on starting at 12 p.m. ET (16 UT). Ask us anything!

| How does the immune system react to proteins from other humans/cell cultures of human cells? Posted: 29 Apr 2021 04:27 AM PDT I'm asking this in the context of (recombinant) monoclonal antibodies as drugs and vaccinations like the one produced by Astra Zeneca, which is produced in HEK cell lines and contains some small amounts of HEK proteins. In the case of monoclonal antibodies there is the generation of antibodies against the used MC-antibodies but as far as I know the risk of immunogenicity gets lower with higher amount of "human" parts of the antibody. Does this happen because the constant region of antibodies is a highly conserved sequence (not sure if it is?) so production of antibodies against this region is unlikely or is there a completely different mechanism involved? In the case of HEK proteins or proteins from other humans in general how does immune response look like? Why does the immune response to proteins from other humans not matter (blood donation) but in other cases it does? Is there some fundamental building block I am missing? [link] [comments]  |
| Posted: 29 Apr 2021 03:52 AM PDT I'm going off of this video here. I have zero background in this kind of thing, just curious. Seems to me if one blocked stacked on top of another block has more mass because it's higher up, that an object much further away would have even more mass due to its greater potential energy.

| Does the gap between the two doses of COVID vaccine affect the efficacy? Posted: 29 Apr 2021 01:03 AM PDT Most people have 2 weeks to maybe a month gap between the first and second dose. How about if the gap is longer than that? If the second dose is given 6 months after, for example, does it give the same level of protection afterwards compared to the recommended gap?

| Why do synchrotrons require pre-acceleration beamlines? Posted: 29 Apr 2021 07:03 AM PDT Or in other words: Would it be possible to inject particles directly into the RF cavity that provides the acceleration for synchrotrons? I understand that pre-acceleration make sense as storage rings from a "beam-economical" point of view, but are they (or other pre-acceleration structures like linear accelerators) unequivocally necessary? Can synchrotrons accelerate particles from low speeds? Thanks in advance! [link] [comments]  |
| How would the the value for the mass of a black hole be estimated using spectral data? Posted: 28 Apr 2021 09:24 PM PDT Googling this only shows up papers on reverberation mapping and the virial theorem, but how do these actually work in regards to estimating the mass and what tools or programs would you need? [link] [comments]  |
| Why do red letters on a blue background seem to shimmer or flash when viewed in peripheral vision? Posted: 28 Apr 2021 06:12 PM PDT I have a t shirt that's deep blue but has crimson letters on it. When I look directly at it nothing seems unusually but I've noticed that when it's in my peripheral vision like when I'm using my phone for example, I notice the red letters seem to jump around and kind of flash when my eyes move. What's causing this? I thought it might have to do with chromostereopsis but I was hoping someone might be able to give me an in depth explanation. [link] [comments]  |
| How do virophages work if viruses don't have cellular machinery? Posted: 28 Apr 2021 01:35 PM PDT I don't know much about this subject, but with some quick searches I saw that virophages require co-infection of another virus. Isn't the goal of a virophage to reproduce just like anything else? So what's the point of them infecting a virus? [link] [comments]  |
| Can getting blood drawn itself cause a vasovagal response? Posted: 28 Apr 2021 03:25 PM PDT Sometimes when I get blood drawn, I pass out, and the doctor always tells me that it's because I get anxious or because I'm afraid of needles or don't like the thought of blood. But, I don't think any of that is true. I don't pass out when I get shots or finger pricks. Is it possible that losing the amount of blood required for a blood test on its own could cause the same response?? [link] [comments]  |
| Variolation- why was is less deadly than naturally contracting the disease? Posted: 28 Apr 2021 10:30 PM PDT Title says it all, and I much appreciate the time. I prefer a nuanced, though not necessarily technical (only that which is pertinent), answer. But of course, any information is appreciated. Many thanks! [link] [comments]  |
| Posted: 28 Apr 2021 11:30 AM PDT Numerous COVID-19 variations are emerging and those that are more contagious (and resistant to vaccines) seem to be spreading more quickly in many countries. Is this a real-world example of "survival of the fittest" from Darwinian evolutionary theory? Those variations that are most fit with their host are more likely to spread and survive.

| Posted: 28 Apr 2021 10:45 AM PDT There seem to be a lot of conflicting reports on this and I'm guessing it's still early to understand it well but wondering if there are at least any trends yet. Whether it's data for one of the vaccines or any combination of them that require two doses, what % of people who have received dose 1 of 2 are getting infected and being admitted to hospital or ICU? If that number exists anywhere, is it known roughly how long between the dose and the severe symptoms? Appreciate any insight as always! [link] [comments]  |

| Posted: 28 Apr 2021 03:09 AM PDT Aside from lowering the osmotic gradient between soil and root, why is salt (or perhaps sodium/chloride ions) toxic to plants? [link] [comments]  |
