| Is it true some prey taunt predators? Posted: 26 Jun 2021 08:35 PM PDT I heard somewhere gazelle are so fast, they are quite cocky and will taunt cheetahs by displays of athleticism, kind of like saying "try me; I am fast." Or how some zebras may display an aloof or cool nature while looking directly at lions, and then you learn that some zebras have actually killed lions by kicking or ganging up on them. How did this happen, evolution wise? When does a prey determine when to run and when to fight and why? And how is it smart to make a predator angry by taunting them? Wouldn't that lessen your chance of survival if he picks you out? [link] [comments]  |
| Posted: 27 Jun 2021 12:00 AM PDT We know that electricity does not need matter (e.g. induction chargers work in a vacuum / in space) as well as light (seen from space yet space is a vacuum) so I'm wondering what the field medium could be. [link] [comments]  |

| Can humans really use Echolocation like bats? Posted: 26 Jun 2021 06:08 PM PDT Here is an article I saw. https://www.sciencemag.org/news/2019/10/echolocation-blind-people-reveals-brain-s-adaptive-powers [link] [comments]  |
| Combining vaccines to increase efficacy? Posted: 27 Jun 2021 04:48 AM PDT Are there any trials being conducted on combining different vaccines to fight against Covid 19? For example, administering 2 doses of Pfizer and then injecting Sputnik or Moderna. Is this possible? If yes, will the efficacy shoot up? [link] [comments]  |
| Posted: 26 Jun 2021 06:33 PM PDT When volcanos first erupt and send the magma flying, is it still magma until it hits the ground? Does it become lava the second it's above ground? Is there a third, airborn state? [link] [comments]  |
| What is the risk for developing long term effects or other severe side effects from COVID 19? Posted: 26 Jun 2021 01:05 PM PDT From what i understand long covid seems a really important issue but the coverage on it seems to have dropped the last few months. Also i dont understand why the odds of getting myocarditis from the mRna vaccine gets so much coverage especially to young people but the odds of getting myocarditis from covid is never mentioned. Isnt this "unfair" to the vaccine ? [link] [comments]  |
| How do we know that all galaxies are going to combine into one in billions of years? Posted: 26 Jun 2021 01:42 PM PDT I remember hearing about this from a nasa post or a verified astronomer and they said everything is going to move to one point in the universe. [link] [comments]  |
| What happens to Viral DNA after the Host "Defeats" The Virus? Posted: 26 Jun 2021 08:15 PM PDT If I were to get, say COVID, and recover, is the remnants of the viral DNA washed out with excrement or urine? Is it absorbed into the blood stream? Something else? I only have A-GCSE Biology 20+ years ago, so go easy on me. Many thanks, kind redditors! [link] [comments]  |

| Why doesnt blood reject like organs do? Posted: 26 Jun 2021 08:56 AM PDT When someone gets an organ transplant, they're on anti rejection meds permanently after that. Why doesnt blood work the same way during transfusions? [link] [comments]  |

| Posted: 26 Jun 2021 01:37 PM PDT I understand we use radio waves, microwaves, visible light and other radiation that falls on the electromagnetic spectrum. Beyond this what else can we use to detect / observe the happenings in space. I understand that there is a whole lot of vacuum in space so we can't really use audio, but what other sensory information is / can be used. [link] [comments]  |
| Can black hole really kill? (theoretically) Posted: 26 Jun 2021 12:36 PM PDT Hello, I'm not really astrology master... but we know black hole has some extreme gravitational force and other things... but its not confirmed they kill you... so it's theoretically possible to "survive" and "fall" into the core of the hole? (Cause we don't know how it works in this mystery object) [link] [comments]  |
