| 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:

| 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.? [link] [comments]  |

| 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?

| 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? [link] [comments]  |

| How can lasers cool things down? Posted: 31 Jan 2020 07:48 PM PST Was looking at atomic clocks and there's a chart of atomic clock evolution and the revolutionary tech seems to be "laser-cooled clocks" Lasers are know for burning stuff, if they can cool things, then how? [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. [link] [comments]  |
| Posted: 31 Jan 2020 05:29 AM PST Very curious as to the answer now with all the coronavirus thing going on and how "immunocompromised" people get it worse [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? [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| [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!

| 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. So I'm asking when the atmospheric composition shifted to one close enough to today that I could explore it without an air tank. [link] [comments]  |
