What does the other side of my belly button look like? Posted: 28 Jul 2020 12:25 AM PDT I'm not even sure this is a meaningful question to ask. Is this just a divit in my belly, and the other side is just flat flesh? submitted by /u/Aimuari_ [link] [comments]

Do all non-plant life forms have pleasure responses to induce them to eat/mate? Is this true for bacteria/microbes? Posted: 28 Jul 2020 05:56 AM PDT People and animals like eating. Are smaller and more simple life forms motivated the same way? submitted by /u/wirelesstoaster [link] [comments]

Can rocky planets have rings? Posted: 28 Jul 2020 07:51 AM PDT All of the ringed planets in our system are gas giants. Is that just a coincidence, or do rings depend on a certain size or gravity in order to form and remain stable? submitted by /u/JasnahKholin87 [link] [comments]

If you don’t cover your nose while wearing a mask, how much benefit reduction is there? Posted: 28 Jul 2020 06:29 AM PDT When we see people not wearing face masks over their nose, there's a lot of people saying, "Why bother?" But there has to be some benefit to covering the mouth alone, right? Just wondering what sorts reduction in benefit is happening here. submitted by /u/TowerRock [link] [comments]

Is there a difference between haemoglobin-deficiency and erythrocytes-deficiency? Are they the same? Posted: 28 Jul 2020 03:39 AM PDT I have trouble finding a precise answer for this... this is what I know so far: The cause (for both?) is lack of iron. Which results in lack of red blood cells/haemoglobin = anaemia. So if that's the case, it seems like you can use them interchangeably... but at the same time I'm thinking why use separate words then? If this is false please let me know! Any help is greatly appreciated. submitted by /u/g6won [link] [comments]

How does the SARS-CoV-2 replicative machinery differentiate viral RNA from host RNA? Posted: 28 Jul 2020 08:23 AM PDT How do the nonstructural proteins of SARS-CoV-2 avoid replicating human RNA while they are replicating the SARS-CoV-2 genome? submitted by /u/dusty_pebble [link] [comments]

How does kinetic force translate to an electric signal in nerves? Posted: 28 Jul 2020 04:13 AM PDT For example, when i hit my ulnar nerve at the elbow with an object, how does the kinetic stimulation produce the characterstic tingling sensation in the rest of my arm ? submitted by /u/Darthfamous [link] [comments]

Why and how crystallization of silver and gold happen? Posted: 28 Jul 2020 06:55 AM PDT I learnt that this can happen to ancient coins, and they become very brittle. submitted by /u/autogenerated1 [link] [comments]

Are aerodynamics and hydrodynamics more or less the same bar the medium ? Posted: 27 Jul 2020 09:37 PM PDT For example, take a Formula 1 car and run it along the sea floor. Assuming the sea floor was flat, would the same principles of downforce apply ? Would you still get a Venturi effect underneath the car ? If the undertray suddenly lost that effect, would the front end rise up and flip the car backwards ? Would a plane wing still exhibit lift ? submitted by /u/PeteUKinUSA [link] [comments]

Is The 10,000 Hour Rule Myth or Reality? Posted: 27 Jul 2020 11:43 PM PDT submitted by /u/itsshuvra [link] [comments]

Was Pangea mostly flat? Posted: 27 Jul 2020 10:01 AM PDT I was driving across the US Midwest last night reflecting on how flat it is. As I understand it, hills and mountains form when the earth's tectonic plates shift. Since Pangea existed before plates shifted, does this mean that Pangea was mostly flat compared to today's geography? submitted by /u/aloe-ha [link] [comments]

When does the heart start pumping? Posted: 27 Jul 2020 12:17 PM PDT The heart pumps blood which is the basis for other functioning organs. But when does the heart start pumping and what starts the heart in the first place? I assume theres much facilitation from the mother, but what are the requirements for a self sustaining heart and when is the heart actively doing its job? In other words what is developmentally necessary for the fetus to begin pumping blood? submitted by /u/Gbayne18 [link] [comments]

What dictates a hurricane's path? How accurately can we actually predict it? Posted: 27 Jul 2020 05:35 PM PDT Hurricane Douglas came knocking on Hawaii's doors but very graciously went northwest and just said hello to all the islands. submitted by /u/alohabrohah [link] [comments]
