| Posted: 03 May 2020 10:03 AM PDT I have a B.S. in biology so I'm not looking for an explanation of how invasive species. I'm looking for more information on this particular invasive species and how it might impact an already threatened honey bee population. [link] [comments]  |
| Posted: 04 May 2020 04:00 AM PDT I am an astrophysicist and author of Galileo and the Science Deniers. I am a Fellow of the American Association for the Advancement of Science.You can see a few of my presentations and interviews (including one on Jon Stewart's show) at: https://www.mario-livio.com. I have published more than 400 scientific papers on topics ranging from Dark Energy and cosmology to black holes and extrasolar planets. My new book, Galileo and the Science Deniers, explains many of Galileo's important discoveries and describes his fight for intellectual freedom and against science denial. Centuries later, we unfortunately still encounter science denial, and we cannot take intellectual freedom for granted.
I also authored six other popular science books, including "The Golden Ratio" (an International Bestseller which was awarded the "Peano Prize" and the "International Pythagoras Prize") and "Is God A Mathematician?" (which was the basis for the 2016 Emmy-nominated NOVA program "The Great Math Mystery"). My book "Brilliant Blunders" was a national bestseller, and was selected by the Washington Post as one of the "2013 Best Books of the Year." Thanks to the moderators for hosting me and I look forward to discussing Galileo, astrophysics, and the importance of science. I'll be ready at 2pm (ET, 18 UT), AMA!

| What is it about STEM CELLS that make them so effective? Posted: 04 May 2020 07:13 AM PDT So in UAE Stem Cell Centre, they extracted stem cells of the patient, activated it, turned it into a mist and made the patient sniff it. This apparently regenerated lung cells and modulated the immune response to keep it from overreacting to the COVID-19 infection and causing further damage to healthy cells. It worked successfully on all the 73 patients without any side-effects. So how did this process exactly worked? And why are stem cells so imp in generating specific healthy cells?

| How would Continental Drift Affect the climate on a planet around an M type star? Posted: 04 May 2020 05:31 AM PDT I am a bit of a world builder, but I would like a more scientific answer. I know that the planet (if it is habitable) will be divided into rough day, night, and twilight sides, but those would seems variable in range. Plate tectonics, mountains, and volcanic eruption would certainly all play roles in how big each of these three zones would be. I am just curious how. [link] [comments]  |
| Why is americium used in smoke detectors and not any other transuranic element? Posted: 03 May 2020 10:39 PM PDT From what I know, americium-241 is used in smoke detectors as it is an alpha emitter, which ionizes air when it decays. Is there a reason as to why this isotope is used and not other radioactive isotopes? Or is americium just much easier to produce on an industrial scale? [link] [comments]  |
| Posted: 04 May 2020 01:52 AM PDT To further clarify. The first question. If they had infinite density, wouldnt that mean that an object at the event horizon would feel the same powerful pull as an object 50 light years away, or even further? The second question. I think i did a well enough job asking but if you need me to be more clear about the question, i'll gladly update with an edit. [link] [comments]  |

| How is the collapse of the wavefunction instantaneous? Posted: 04 May 2020 04:10 AM PDT The way I see it is that there is an input (observation) that yields an output (result of eigenvector decomposition of observation matrix). To me this seems like an energy intensive process, after all it is a change of state. I am aware that no evidence has been found yet for a finite time of wave function collapse, and the commonly held belief is that the process is instantaneous. So my question is, how is this physically possible? Is it not more likely that the wave function collapse occurs over a finite timescale that is smaller than we have currently been able to measure? If you were to mathematically describe the process to a computer, it would require processing time to reach the answer. Is the mathematical formulation of the problem the reason then for the processing time? What I mean to say is, eigenvector decomposition seems to be a energy intensive process. So how can the system do it instantaneously? Or does the system not do it at all, and the mathematical formulation is just our way of understanding the underlying physics, whereby the underlying physics does it in a non energetically intensive way? Please correct me where I'm wrong, it's been a while since university. [link] [comments]  |
| Posted: 03 May 2020 05:15 PM PDT Here is the article in reference. It goes on to state that the systems on the aircraft are specially designed to account for this (I presume they use ECC RAM). Why don't laptops and phones with standard RAM encounter more memory errors during flights? Is it simply that they do but the user doesn't realise it? [link] [comments]  |
| Can children or adolescents develop Alzheimer's ?? Posted: 03 May 2020 05:34 PM PDT My old neighbour texted me to catch up, he's a lot younger (15 or 16 years old) but then he said he was diagnosed with alzheimers since moving back to germany. I tried googling it but cant seem to find any legit cases of children with alzheimers.. does anyone have any input? [link] [comments]  |
| How strongly does color perception depend on the language used? Posted: 03 May 2020 03:16 PM PDT I recently came across this explaining that brown is just dark-orange. The only reason wee see it as a distinct color is, because we gave it its own name. So dou you know a language where brown is just called "dark-orange" and if they see it as dark-orange? Or do they have an own name for a color we don't have and therefore see it as an own color? And do you know of any other case where our language controls our perception? [link] [comments]  |
| Why do dogs have little slits on the outside of their nose? Posted: 03 May 2020 10:27 AM PDT When I get really close to my dog, I see small slits on the sides of his nose. What are these for? [link] [comments]  |
| How does radiocarbon dating work on manmade structures? Posted: 03 May 2020 10:48 PM PDT I have a general understanding of how radiocarbon dating works. But I was recently reading the Wikipedia page for Stonehenge and read the following: "Radiocarbon dating suggests that the first bluestones were raised between 2400 and 2200 BC, although they may have been at the site as early as 3000 BC." How would radiocarbon dating work on an inorganic substance? Furthermore, how could they date the construction of the Stonehenge with radiocarbon dating? [link] [comments]  |
| What are the main problems to performing a successful head transplant? Posted: 03 May 2020 10:19 AM PDT I ask this question as I remembered a scientist recently claimed to be able to transplant heads (body?) successfully, his name was Sergio Canavero, He made a lot of claims but haven't heard from him in awhile, So I wanted to know what's the feasibility of his plan working and what would be the greatest barriers to success.

| what is a Lagrangian function? in the context of SM Field Theory Posted: 03 May 2020 05:46 PM PDT Now first off, I would like to recognize that this is something that generally is only understood by completing multi-variable calculus and high level physics courses. However, the highest math I have is very basic calculus and College Physics 1. And outside of waiting x years this seemed like the best place to get answers. The question essentially boils down too, if a paper was referring to a theorist constructing a Lagrangian function in the context of quantum field theory, what, function would that equation serve? The specific context is: "Weinberg constructed a Lagrangian that includes all matter particles 'plus a spin-zero doublet' whose vacuum expectation value will break T (Gauge group generators) and Y (Hypercharge gauge group generators) and give an electron its mass" TL;DR: High school student annotating a paper, came across the Lagrangian function but have no idea what it might be used for [link] [comments]  |
