| Why are lithium and beryllium relatively rare? Posted: 18 Apr 2019 03:26 PM PDT I understand that active stars are mostly hydrogen and helium, and heavier elements are created when they get older or if they're huge and go supernova. But it's weird to me that here on Earth, we have loads of hydrogen, carbon, oxygen, nitrogen, etc. But these two light elements on the periodic chart seem relatively rare. Am I wrong about their rarity, or is there something else going on? [link] [comments]  |
| How do modern supercomputers work? Posted: 19 Apr 2019 12:15 AM PDT When I look up info about modern supercomputers, the (very generalized) specs are that it's racks upon racks of CPUs and a huge amount of RAM. Topology-wise, this seems to mean an enormous amount of rack mounted motherboards with multiple processors and lots of memory, and there's some sort of operating system that manages all these (seemingly) parallel systems to distribute workload. My question is, what kind of details are there for said systems? Seems like it's more of a shit ton of individual systems that are linked for parallel processing, the idea makes sense (distributed workload) but how is this accomplished? What operating system do these systems use? How is the programming written so that the problem takes advantage of the massive parallel processors? How do these systems differ from a typical workstation? [link] [comments]  |

| Where does the funding for all the fundamental physics research come from? Posted: 18 Apr 2019 11:59 PM PDT Hence, who is investing and what economic payoffs are expected from e.g. CERN, black hole imaging, etc. ? [link] [comments]  |

| Can prions affect non-nervous tissue? Posted: 18 Apr 2019 06:22 PM PDT If prions are simply misfolded proteins, can these misfolded proteins appear in non-nervous tissue? Is it possible that there are prions that mainly affect non-nervous tissue such as muscle tissue? [link] [comments]  |
| What is the fire being burned on ocean oil rigs? Posted: 18 Apr 2019 04:15 PM PDT There is an image I'm looking at, and I've seen this before, where on an ocean oil rig a small shoot exists that pushes a stream of fire of into the water. Why do oil rigs burn oil like this? There must be a reason, because otherwise this would be a little dangerous! [link] [comments]  |
| Does light from our Sun's photosphere get redshifted before it reaches us? Posted: 18 Apr 2019 05:16 PM PDT Since the Sun's mass creates a giant gravity well that the photons it emits need to escape; do those photons get appreciably redshifted prior to reaching the Earth? Or put another way, does sunlight 'change colors' as you get closer? [link] [comments]  |

| Are climate zones changing due to global warming? Posted: 18 Apr 2019 01:50 PM PDT I live somewhere close to tropic of cancer. Where I live, it's considered to be a temperate/semi arid climate zone . Right now, it's summer here. As far as I remember and as far as my parents remember, the summers here have always been very hot days (even hotter now) and quite breezy nights. But this season, it's blistering hot during the day time and it's starting to rain heavily during the nights. From what I've learnt, hot days and rainy nights is a feature of rain forests. Is this a consequence of global warming or is it due to some other meteorological event? If not, what will be the impact of this on local flora and fauna? [link] [comments]  |
| How do E&M instruments which require extreme precision account for the Earth's magnetic field? Posted: 18 Apr 2019 04:27 PM PDT From what I know, Earth's natural magnetic field is constantly changing, although the changes are extremely small. (Except for when it "flips".) So how does an instrument account for this? You can't just "zero it out" like you can with a mass scale, because it might change afterwards, right? [link] [comments]  |
| Posted: 18 Apr 2019 01:44 PM PDT Okay so I'm leaning about immune function right now, and I understand the MHC interactions with T cells (CD4 for helper, and CD8 for killer). So it makes sense to me that when a cell is virally infected and displays foreign antigens, the T cell would recognize the self MHC protein, and foreign antigen protein and then destroy the cell. But what about bacterial cells, do they have MHC molecules on their surface? If not, how would T cells destroy them? Or are bacteria destroyed by macrophage and neutrophils exclusively? And do bacteria infect cells similar to how a virus does? Please correct me if I'm wrong about anything, thanks! Tl;Dr need to know how T cells function regarding both the presentation of an antigen and MHC molecule, and whether different tactics are used to destroy virally infected cells, bacteria, and/or bacteria infected cells (if that's a thing) [link] [comments]  |
| What created the gasses and meteors in space after the big bang? Posted: 18 Apr 2019 02:57 PM PDT What I mean more specifically, is before the expansion started was there gasses, rocks, and other things? like how did these things come to be if there wasn't anything to start with?
