| Is there any instances of animals domesticating other animals? Posted: 09 Aug 2020 07:31 PM PDT edit Yeah guys I get it, humans are animals too. I meant other animals. [link] [comments]  |
| Have we figured out how to “translate” whale language yet? Posted: 09 Aug 2020 11:38 PM PDT With their massive brains and ability to make hundreds and/or thousands of different sounds and pitches and squeaks and squeals etc that travels hundreds of miles - and apparently they have extremely good memory too... Wouldn't it be conceivable that whale language could be almost as sophisticated- or possibly even more sophisticated- than human language? With "words" for different types of sea creatures, boats, night and day, sex, food and maybe even names for family and friends? I feel like they gotta have this on some level and I'd be super curious to know how much we know. Itd also be super cool if we could translate their language and play it back to them on underwater speakers and "talk" with the whales! If I ever become a billionaire (give it time boys, give it time 😤😎🤣), I'm gonna pay the nerds until they figure out a way to carry out full on convos with the orcas lfg [link] [comments]  |
| Posted: 10 Aug 2020 07:16 AM PDT Recently saw a video where a baby got correction glasses and was able to see it's parents properly for the first time. How do parent get to know their kids have issues with seeing and even if they do, how are doctors able to correctly prescribe them glasses [link] [comments]  |

| Do humans have any unique organisms? Posted: 09 Aug 2020 02:42 PM PDT I understand we are made up of trillions of other cells that out number our own. But are any of them only ever found in humans? [link] [comments]  |

| How is the efficacy of vaccines verified during phase III trials? Posted: 09 Aug 2020 08:34 PM PDT In relation to the current COVID-19 vaccine in phase III trial. How do the researches know the people who received the treatment were exposed to the virus? If a person receives the treatment but is never exposed, how do the researchers count this out? Or do they? If they never were exposed wouldn't it create a false efficacy for the treatment? [link] [comments]  |

| Do male marsupials have nipples? Posted: 09 Aug 2020 08:12 PM PDT I know this is a dumb question, but there doesn't seem to be any kind of answer for some reason. I'm pretty sure most male placental mammals have nipples (please tell me if I'm wrong) but I can find no answer as to marsupials and whether males have them too despite having no pouch. I've seen this question asked before but for some reason every time the only answers seem to be "marsupials don't have nipples they have (thing that's close enough to nipples)" and then not answering the question so I have no idea what the actual answer is. Sorry if this is dumb and obvious, and for the repost but my first attempt shows as removed for some reason even though I didn't remove it. [link] [comments]  |
| Posted: 09 Aug 2020 01:47 PM PDT mRNA vaccines are an exciting new hope for combating rapidly changing viruses like the corona viruses, and for rapidly providing a response to emerging diseases like Zika and Ebola. mRNA is the code used by our own cells to produce our own proteins and they are also, at least in part, how viruses corrupt our own cells into producing virus progeny. While viruses are simple, the complete virus genome is coding for multiple proteins and multiple other genetic instructions, resulting in a complete virus package. It makes sense to me how completed viruses can be identified as an invader and be attacked by our immune system. (It doesn't really make any sense to me at all, but it makes more intuitive sense to me than my ultimate question.) So, how can a greatly shortened version of the virus genome, the code for only single protein, be flagged as an "invader," warranting an immune response, and not ignored as a friendly protein that is good and "self?" Is it a flood to the system of an otherwise unused protein? How can we sure we won't trigger an immune response to a friendly protein by accident? [link] [comments]  |
| How does a radio know what sound frequencies to play? Posted: 09 Aug 2020 12:28 PM PDT If radio towers broadcast at one specific frequency of radio waves, how does the receiver know what sound frequencies to play? [link] [comments]  |
| Posted: 09 Aug 2020 11:02 AM PDT We obviously saw massive pollution drops when people were under lockdown but how much of that actually gave us a bigger window to address climate change? How much time would people need to stay at home to notice an impactful difference? [link] [comments]  |
| Is UV effective to kill coronavirus? Posted: 09 Aug 2020 10:42 AM PDT Are commercial UV appliances effective to kill/disable the coronavirus in refrigerated settings? If so, how long? Also what is the science that this virus is infectious after being aerosolized into hvac systems? [link] [comments]  |
| Posted: 09 Aug 2020 03:23 PM PDT I'm sorry I just never really fully grasped the point of this. [link] [comments]  |
| What makes cancer immunology treatment so ineffective? Posted: 09 Aug 2020 06:45 AM PDT I read that editing immune cells and reinjecting them into the body only works in about 1 in 5 patients. So what exactly makes it so ineffective? [link] [comments]  |
| Is the damage potential of an explosion linear with equivalent tonnage of TNT? Posted: 09 Aug 2020 07:53 AM PDT I've been reading about how the Beirut disaster was caused by an explosion with the equivalent of 3KT of TNT, which is about 1/5th of the estimated size of the Hiroshima blast. I have heard that it's the shockwave from the blast that does all the real damage. Is the magnitude difference in the power of these shockwaves, and their destructive ability, proportional to difference in TNT tonnage? [link] [comments]  |
