| Posted: 08 Jun 2019 08:55 AM PDT This might be a stupid question straight outta my stoned mind, but most metals i can think of can be either solid or liquid depending on temperature. So if heated enough, can any metals become a gas? [link] [comments]  |
| What makes elements have more or less density? Posted: 09 Jun 2019 05:57 AM PDT How come osmium is the densest known element while other elements have a higher atomic number and mass? Does it have to do with the Higgs boson particle? [link] [comments]  |
| Why heavy water is toxic, while ordinary water isn't? Posted: 08 Jun 2019 11:15 AM PDT If chemical properties of substances depend only on the outermost "layer" of electrons around the molecule, how come ordinary water isn't toxic, while heavy water is? [link] [comments]  |

| Posted: 09 Jun 2019 07:12 AM PDT Solanine is a poison in potatoes and sarin is a nerve agent/chemical weapon while galantamine is a pretty safe pharmaceutical and huperzine A is an OTC nootropic, despite the fact that all of them are acetylcholinesterase inhibitors. Why is that? [link] [comments]  |
| How can sprouts be nutritious if their only source is water? Posted: 09 Jun 2019 07:09 AM PDT They sell online "Seeds Sprouters" where you have to fill water for some days and then you can eat the sprouts. Sprouts are normally a high nutrient food, with a lot of vitamins and minerals. My question is: How can a sprout can have a high nutritious value if their only source of "food" is water and sun (and not soil)? [link] [comments]  |
| Posted: 09 Jun 2019 02:34 AM PDT We hear all the time that a smartphone with 8 cores is nowhere near as powerful as a desktop PC with 8 cores, and this is mostly chalked up to the smartphone having 8 ARM cores which are weaker computationally than 8 x86 cores, but what aspect of a CPU core design makes it better or worse at computing than another design? Hypothetically, if I wanted to make an ARM core as powerful as an x86 core, what would I change about it? [link] [comments]  |

| Do euglenas and plants have same chloroplastes? Posted: 09 Jun 2019 07:41 AM PDT I know euglenas can have structures with membrane so they can have chloroplast. So do their chloroplast and plant's chloroplast are from same origin? Are their chloroplast's DNA similar? Or are we just calling a bunch of chlorophylls with a membrane and a dna "chloroplast" so their origin is not dependent? [link] [comments]  |

| Are there viruses that target viruses? Posted: 09 Jun 2019 07:04 AM PDT Given that we have for example phages that specifically target bacteria is there something that is like a virus for virus? Not counting antiviral medication. [link] [comments]  |
| In basaltic magma, how much is recycled crustal material and how much is mantle material? Posted: 09 Jun 2019 05:54 AM PDT I'm curious about both mid-ocean ridge and mantle plume/hot spot magmas, and potential differences between the two. From what I can gather, granitic magmas usually result from recycling of crustal material at subduction zones; but I'm not so clear on the composition of basaltic magmas. How much of the material at mid-ocean ridges/hot spots originates deeper in the mantle and is brought up by convection, and how does this interact with the astenosphere and moho? Thanks!

| What do you call the gene that HIV virus integrates in the cell? Posted: 09 Jun 2019 05:54 AM PDT What do you call the transcripted RNA (which is then known as DNA) that HIV virus integrates? [link] [comments]  |
| Does the pancreas serve as a receptor and a modulator for blood glucose? Posted: 08 Jun 2019 08:14 PM PDT We all know that the pancreas can respond to blood sugar levels by secreting insulin or glucagon, but does it detect these levels itself with its own chemo-receptors or is this job done by another organ such as the hypothalamus?

| How does Electro-Convulsiveshock Therapy work? How does it cure things like depression? Posted: 08 Jun 2019 02:29 PM PDT As I'm currently looking down the ECT barrel due to what my psychiatrist called "treatment-resistant depression," I was wondering how exactly it does what it does. Unsure if this post will get disqualified due to rule 1, but I'm looking for all the chemistry/biology, maybe even a little psychology behind it. I've heard the whole "it restarts the brain" thing, but I want to know the entire process behind it. [link] [comments]  |
| Posted: 08 Jun 2019 09:10 AM PDT Once the severed arteries/veins are closed off to stop bleeding by the healing process, the heart would keep pumping blood along the previous complete circulatory system and when blood reaches the closed off part of the artery, it has nowhere to go. Similarly the vein exiting from the wound will never have blood in it again. Will the circuit complete itself somehow? If so what is the mechanism used to find the openings of the respective major artery and vein and how do they join? [link] [comments]  |
| Do humans who live in very hot/cold climates have a greater resistance to heat stroke/frostbite? Posted: 08 Jun 2019 05:36 PM PDT I do know that there is the stereotype that people in hot climates will adapt to it and not feel the heat nearly as much as someone who lives in a colder climate, and vice versa. But I was wondering if this extended to being more resistant to extremes like heat stroke or frostbite? Or if that level of temperature evened the playing field? [link] [comments]  |
| Why does the air «shake» when hot? Posted: 08 Jun 2019 09:59 AM PDT Whenever it's really hot, you can sometimes see the air kind of shake. Forexample when you open your car, and it's really hot inside after being in the sun for a couple hours, you can see the shadow doing this weird shake motion. Another example is when an engine is running, wherever the engine is blowing the hot air out, you can see the air shake. [link] [comments]  |

| How much do air rotors impact wildlife? Posted: 08 Jun 2019 11:56 AM PDT I saw a post on reddit on how wind turbines kill birds and insects. How would putting up a lot of turbines compare to other types of energy? Could a lot of turbines have a large effect on wildlife in the long run? [link] [comments]  |
