How do chargeable battery-powered devices handle grounding? Posted: 02 Feb 2020 04:06 PM PST Imagine something like a laptop or cell phone. When it's not plugged into anything, just operating on battery power, it has some ground potential. Now imagine you plug it into a charger, which has a ground potential defined by the wall outlet. As far as I can see, there's no reason why these two ground potentials have to be the same. How does the hardware handle a changing ground potential? submitted by /u/NoEscort [link] [comments]

How do we know know which way is up in space? Posted: 03 Feb 2020 12:59 AM PST We talk about the earth rotating counter clock wise and have our map of how the earth sits in space but how do we know we are looking from the right angle?

Human Embryo: Where does the ectoderm come from? Posted: 02 Feb 2020 04:33 AM PST Hello. I'm currently studying the development of the human embryo, going from the zygote -> morula -> blastula -> gastrula -> neurula. When I was studying the blastula from human embryos, I learned about its three mains components: 1- blastocele: full of liquid (where does this liquid come from, btw?) 2- trophoblasts: outer layers of cells, which will go on to form the placenta and other uterus/embryo structures (will not be a part of the baby's body) 3- embryoblasts: group of cells within the blastula that will go on to become the baby itself (organs, tissues, ...) All blastula -> gastrula picture that I've seen, show the invagination of the blastula to become the gastrula, and, from these pictures, it always seems like the trophoblasts become the ectoderm, which I know is not true (because the trophoblast will only form embryo/uterus structures). So, where does the ectoderm actually come from? it must be from the embryoblasts right? And why do all pictures on the web/textbooks make it look like it comes from the trophoblasts? Thank you! submitted by /u/gui93 [link] [comments]

How do counterweights on construction cranes not tip the crane before loads are hoisted? Posted: 01 Feb 2020 03:13 PM PST I know that the tipping of cranes is caused when the torque generated by the load exceeds that of the counterweight. But if a crane were to have no load attached, i.e it is preparing to pick one up and the counterweight is attached, how does it not tip in the time before any weight is able to generate torque against the counter weight? submitted by /u/PDWAMMO [link] [comments]

Can someone please further clarify the process of muscle protein synthesis for me? Posted: 01 Feb 2020 10:59 AM PST As I understand it (and I appreciate much is missing from this): We workout, create damage to the muscle, and eat a protein dense meal. The protein is broken down into amino acids, to which they are then signalled by satellite cells on the damaged muscle to be synthesised into new proteins. The proteins are then synthesised through a variety of hormonal processes that culminate in the assembly of new strings of protein through the mechanisms of RNA replication. The protein can now be shuttled to the muscle to fuse with the nuclei of other cells repair the damaged muscle fibres. I'm trying my best to conceptualise it in easy to comprehend steps like the above. Can you help me formulate the above better and fill in the gaps or incorrect parts? Many thanks! submitted by /u/NT202 [link] [comments]

In the contexts of pain how does Advil and aspirin relieve pain especially in headaches and why do drugs like eloquis or blood thinners in general cause headaches? Posted: 01 Feb 2020 11:45 PM PST I understand as far that both advil thins blood to a point and that aspirin is an anti platelet and most drugs have more than one effect on the body. submitted by /u/ProudOwnerOfYourFish [link] [comments]

Why do myeloma cells with their H and L chain left intact cause differences in IgG when forming hybridoma cells? Posted: 01 Feb 2020 12:34 AM PST Hi, why is it that if you keep heavy and light chains in myeloma cells they cause lots of different forms of antibodies? After antigen is presented to the mouse for the mouse to form antigen specific antibodies and then these cells fused with myeloma cells, why do changes to the specific antibodies occur if you have the heavy and light chains in the myeloma cells? Hybridomas made with myeloma cells where the immunoglobulin genes have been made nonfunctional causes formation of the homogeneous immunoglobulins. How does the light chain and heavy chain affect this that it makes heterogeneous immunoglobulins. submitted by /u/dmitriya [link] [comments]

Have a question about the 2019 novel coronavirus (2019-nCoV)? Ask us here! Posted: 31 Jan 2020 03:00 PM PST On Thursday, January 30, 2020, the World Health Organization declared that the new coronavirus epidemic now constitutes a public health emergency of international concern. A majority of cases are affecting people in Hubei Province, China, but additional cases have been reported in at least two dozen other countries. This new coronavirus is currently called the "2019 novel coronavirus" or "2019-nCoV". The moderators of /r/AskScience have assembled a list of Frequently Asked Questions, including: How does 2019-nCoV spread? What are the symptoms? What are known risk and prevention factors? How effective are masks at preventing the spread of 2019-nCoV? What treatment exists? What role might pets and other animals play in the outbreak? What can I do to help prevent the spread of 2019-nCoV if I am sick? What sort of misinformation is being spread about 2019-nCoV? Our experts will be on hand to answer your questions below!

Can ions exist independently of their oppositely charged pair? Posted: 01 Feb 2020 06:05 AM PST It has always bothered me how if say you dissolve a salt, the ions can only exist as long as there are the same amount of anions and cations. Similarly, if you dissolve an acid, the hydrogen ions exist because there is a negatively charged molecule left over from the acid. Meanwhile, in cells, pumps and transporters can seemingly transport ions away from their pairs. Similarly hydrogen ions/protons are supposed to have enormous charge density and can't really exist on their own, but they drive all sorts of processes in the cell without interacting with anything. I wonder which acid the protons even come from, and if oxonium ions form. If so, are the protons themselves or the oxonium ions transported by proton pumps, ATP syntheses etc.? submitted by /u/WhenVodkaTakesOver [link] [comments]

What techniques are used to measure greenhouse gasses of whole natural systems like a forest or a swamp that produces N2O, CO2 and CH4 but can also sequester carbon? Posted: 31 Jan 2020 08:19 AM PST I know a thing or two about how much biomass can be produced and how much that relates to carbon being sequestered, but how do you measure this of whole ecosystems with so many different plants, animals, with soil and with NO2, CH4 and CO2 being produced or taken up and with so many variables over years. Is it a very labor intensive process to come up with good data, or are there shortcuts with satellite data, or are models in use that have turned out to be very reliable or do we actually guess a lot based upon simplified models? submitted by /u/Manisbutaworm [link] [comments]

Photoelectric effect and electrons explanation? Posted: 31 Jan 2020 02:44 PM PST From what I understand, solar panels are made of materials that can be used with the photoelectric effect. Light reaches the object, and eventually the atoms receive so much energy that electrons break-off the atom and start moving freely. An example of these materials is silicon, a semiconductor. My question is, don't the silicon atoms eventually "ran out" of electrons to release, or where do they get new electrons from? I feel like I am lacking knowledge about this area nd would like someone to explain this to me, if the silicon atoms are constantly losing electrons which we are using for our electricity, wouldn't the silicon eventually "wear out"? Lose all its electrons? submitted by /u/LevyathanBoi [link] [comments]

How do we know global warming is caused by CO2? Posted: 31 Jan 2020 07:37 PM PST I looked it up and the results are just saying there is a rise in CO2 and a rise in average global temp. They don't explain how they connect. submitted by /u/davidnugget6 [link] [comments]

Is the strength of a smell dependant on the quantity or the quality of an odorant? Posted: 31 Jan 2020 01:14 PM PST E.g. skunk smell from roadkill can stay in the car for several miles after passing the corpse. Is this because there is a great amount of odorant being released, or because our receptors react more strongly to the odorant? submitted by /u/Amaculatum [link] [comments]

Where do trees get ”strength” from to destroy pavements with their roots? Posted: 31 Jan 2020 10:19 AM PST As far as I understand it with my highschool knowledge, organisms grow by cell division, so when my leg is growing the cells "in between" the start and the end divide and over time, over time, this process "pushes" my leg into a longer shape. Occasionally, I see tree roots which managed to destroy a pavements with their roots while growing in size. Where do they get this force from to push against a relatively strong obstacle? Edit: How I imagine growing works: Starting situation: |OOO| Middle cell divides...: |O00O| ...And they expand: |OOOO| submitted by /u/maibrl [link] [comments]

Could an osteoclast / -promotor injection be feasible for therapeutic bone loss / removal? Posted: 31 Jan 2020 01:40 PM PST Hello! I am currently a second year medicine student. I was wondering if it was theoretically possible and practically feasible to inject some sort of serum, eg. osteclasts / promotor to remove unwanted bone tissue such as a hemivertebra in the spine without major surgical intervention? The problems immediately apparent are probably efficiacy and specificity. I obviously don´t know very much about the subject so I was hoping someone could get me started on some good literature! submitted by /u/MCrypa [link] [comments]

How far back in time could a person travel and still live in a breathable atmosphere? Posted: 30 Jan 2020 08:40 PM PST My understanding is in the Triassic period the atmosphere was much more rich in carbon dioxide and therefore not habitable to humans.
