Can bacteria, viruses, etc. get diseases just like humans or plants? Posted: 18 Aug 2020 03:41 AM PDT If bacterium, viruses, fungi, etc cause disease, can they themselves get a disease? submitted by /u/throwaway13224343 [link] [comments]

How do they load operating systems onto completely blank computers? Posted: 18 Aug 2020 06:49 AM PDT Say I have a computer that is just the absolutely bare electronics. Nothing to read a usb or any inputs. How would I load an operating system onto it? How do computer manufacturers accomplish this? submitted by /u/byebybuy [link] [comments]

How far up do helium filled balloons go? What is their limit? Posted: 17 Aug 2020 07:00 PM PDT I'm sure we have all lost a balloon or got one that's blew away but how far into the sky does it actually go? You can keep a regular balloon for about a week and Itll still stay floating around your house but when it gets released into the sky does an actually make it through any of the "spheres" or does the volume of the helium prevent it from breaking through? submitted by /u/MA3XON [link] [comments]

As a female, does losing your virginity actually change your body in any way? Posted: 18 Aug 2020 07:50 AM PDT I always see these strange dads obsessed with hymens being intact which made me wonder: is there actually a visible change to the body when virginity is lost? submitted by /u/porno8338 [link] [comments]

Does Enceladus have sub-surface continents? Posted: 18 Aug 2020 12:54 AM PDT I read in a handful of pages that Enceladus is geologically active, referring to tectonic activity in the South polar region. Since the moon has tectonic plates does this mean that the formation of features along boundaries, and the existance of continents or a supercontinent is possible? submitted by /u/AnotherTrashRedditer [link] [comments]

Is it possible to achieve a ‘negative’ shockwave? Posted: 17 Aug 2020 03:11 PM PDT Aside from explosive lenses, is an implosive shockwave actually possible? As in, a region that decreases air pressure so rapidly, that rarefaction can occur faster than the speed of sound, inwards spherically? I understand that traditional explosives can create major shockwaves because their detonation velocities are many times Mach 1, however slower objects like fighter jets and whips can still achieve it to a significant extent. Edit: what I really mean is a near instantaneous decrease in air pressure by a shrinking mass at the centre of an infinite volume of atmospheric pressure air. Rather than beginning with higher pressure air compressing an air mass at 1atm, like a traditional explosive would do. In addition, what would it sound like? I assume that if you're close enough, it'll be similar to a bang from the opposite direction, but at a distance, is it just the sound of a reverberated sonic boom? Or would it be identical as the pressure waves pass through each other? submitted by /u/Chemonaut [link] [comments]

Does Lighting emanate from a single point in a cloud? Posted: 17 Aug 2020 04:40 PM PDT To clarify: I am aware that stepped leaders come down from the cloud, and that current from ground connects to a leader, followed by a massive stroke going upwards. As well as leaders can come from the ground occasionally, different processes exist for cloud to cloud lightning, sprites are a thing, etc. The specific question is, when electricity moves from or to a cloud, since there is no solid surface there, from where does this electron flow flow from, or to? Is it a diffuse area that spreads out in voltage? Visually how would this process appear to a camera somehow stationary in the sky that happened to be looking at the right direction and at the right distance? submitted by /u/Darkside_of_the_Poon [link] [comments]

What is the current pandemic effect on Global Warming?? Posted: 18 Aug 2020 01:20 AM PDT In this pandemic where most of the countries are in halt, causing less pollution to mother earth, are there any recent studies that show that earth is healing from global warming or the difference in pollution level has not much changed since pre-pandemic to now?? submitted by /u/sharmarohan136 [link] [comments]

What causes the baby to turn head down and hold position in the final weeks of pregnancy? Posted: 17 Aug 2020 07:46 AM PDT For a pregnant women, the baby should start to turn head down at around week 33, and hold position until give birth. What causes this to happen? Does the uterus knows how to 'turn' the baby? Theres muscles in the uterus to do this? Or is this the baby's own instinct that he waddles himself to head down? And once the baby is in head down position, how does he maintain that position, but not being drifted away? What's holding him in position? submitted by /u/eatqqq [link] [comments]

Can you train memory and concentration? Posted: 17 Aug 2020 07:39 AM PDT I am curious about this subject but I get the feeling that when I search for this on the Internet everyone who says that you can is trying to sell you something. So my question would be if it is scientifically proven that you can train those things and if doing so would bring you positive aspects to your life. Also I would like to ask to the experts if it is true that the current lifestyle is encouraging the opposite of developing good attention and memory skills and how can you effectively fight this.

What is the current consensus in the field of bariatrics on mitigating obesity?

What is agreeableness in the Big 5, really? Posted: 17 Aug 2020 04:08 AM PDT I took a personality test some time ago, and my results were described as kind of stereotypical nerd -- high in openness and low in agreeableness. Agreeableness was explained to me at that time as a willingness to "go along to get along," which I don't really have much of, seeking solutions to problems more than social unity. Still, people generally seem to think that think I'm sympathetic and try to view disagreements from all viewpoints. I'm generally considered a serious team player, if a bit of a curmudgeon. I've been leading teams for a couple of decades now. So I was surprised when, a few years later (now), I tried to look up the Big 5 out of curiosity and find all manner of definitions of agreeableness, many of which seem to pit it as selflessness on a spectrum opposite selfishness. Others paint it as concern about your own feelings vs others during disagreements. (In this one, where's concern for truth or the best solution?) But again, there doesn't seem to be any elevator pitch for agreeableness that major psychology sites agree on. So what is it, really? p.s. If it ends up being selfishness, I'm definitely taking my personality profile off my CV. Haha. submitted by /u/bodangren2 [link] [comments]

Following anthropogenic climate change, how will Earth eventually cool down again? Posted: 16 Aug 2020 02:04 PM PDT Let's assume the climate will increase by 2 or 3 °C by the year 2100, which is vastly going to change ecosystems all over. And let's assume humans won't figure out a way to store or get rid of the excess greenhouse gases that are heating up the atmosphere (so no carbon capture etc).

Do we know whether Covid is actually seasonal? Posted: 15 Aug 2020 05:30 PM PDT It seems we are told by some to brace for an epically bad fall. However, this thing slammed the Northeast in spring and ravaged the "hot states" in the middle of summer. It just seems that politics and vested interests are so intertwined here now that it is hard to work out what is going on. I thought I would ask some actual experts if they can spare a few minutes. Thank you. submitted by /u/drewski_pz [link] [comments]

Did dust from the Sahara fertilize the Amazon 5 or 10 thousand years ago? Posted: 15 Aug 2020 05:42 PM PDT So, I've seen a number of documentaries stating that the Sahara supply's millions of tons of dust to the amazon every year, which is a major source of nutrients to the generally poor soil there. What about 5-10 thousand years ago, when the Sahara was much wetter and, presumably, much less of a source of dust. Was there another source of nutrients? Was the amazon different then, and didn't need the fertilizer? Do we actually have any idea how it worked that long ago? submitted by /u/jhudsonj [link] [comments]

How exactly do diuretics work? What about them causes your body to release more water than it normally would? Posted: 15 Aug 2020 08:10 PM PDT I know that sometimes they are prescribed for certain conditions, but what makes "normal" beverages such as coffee, tea, or alcohol a diuretic? Is there a particular chemical that the body responds to? Edit: grammar submitted by /u/ace_at_none [link] [comments]

How exactly does a machine replicate a specific sound? Posted: 15 Aug 2020 07:42 PM PDT I may not be wording this entirely correct, but what I am trying to ask is how can a computer or any storage medium for audio incode what the audio sounds like. I understand the physics and computer science and engineering principles behind the parts of a recording and Playback device including how a computer breaks down in stores the information; the frequency etc. However how does it play and store the exact instruments and sound?

Does global warming have an effect on the frequency of earthquakes in the world? Posted: 15 Aug 2020 09:48 AM PDT I know global warming has an effect on other natural disasters like hurricanes, lethal heat waves, and snow storms, as well as landslides and droughts.

Has the COVID pandemic had any effect at all on the environment? Posted: 15 Aug 2020 07:24 PM PDT Last March it seemed that once people stopped driving cars and shut down factories, we began to see satellite images of areas in China and Europe where smog was clearing and air quality was improving. Now it seems the arctic ice sheet is melting and the glaciers in Greenland are going extinct.

Why do COVID-19 deaths go up and down on a weekly cycle? Posted: 15 Aug 2020 03:38 AM PDT (Reposting because it took the mods 2 days to approve and was lost from view by then) It looks odd to me that COVID-19 deaths seem to increase and decrease on a weekly cycle. There is an upward or downward trend of course, but the cycle still remains. See for example: https://ycharts.com/indicators/us_coronavirus_deaths_per_day I can think of reasons why this would happen, for example it could be that doctors work less on weekends and something they are doing is killing the patients more during the week. Or it could be that on the weekends infected children go visit the grandparents and get them infected, and they reliably die a certain number of days afterwards. Reporting differences on weekends are quoted as a reason, but would deaths really go unreported for days? And the lowest death rate per week is usually but not always on a weekend day. Does anyone have a definitive answer or even a really good hypothesis about why we see this cycling in the death rate? submitted by /u/Whybecauseoh [link] [comments]

Why are there so many small tightly packed lakes in the very north of Alaska? Posted: 14 Aug 2020 10:48 PM PDT It is very clear to see on google earth/google maps but when I look up "northern alaska lakes" nothing comes up discussing what seems to be, to me at least, an interesting geographic phenomenon. https://i.redd.it/38ad6x64c9931.png submitted by /u/KnightCyber [link] [comments]

Are the Nile and Amazon rivers the same ancient river? If so, what's that mean exactly? Posted: 14 Aug 2020 08:36 PM PDT I've heard that something about the underlying geography of the Congo and the Amazon is what makes them "destined" to be rivers, and that they were the same river at one point, when these continents were together as one. How likely is this theory? And why is it that these rivers would remain rivers as the continent drifts away? (And I think the theory goes that one had to reverse direction.) Why wouldn't the drifting continent just "roll over" the river and make a new river or no river at all? Edit: Sorry, meant Congo River, not the Nile. submitted by /u/MoronicFrog [link] [comments]
