| If inflammation is bad, why does our body do it? Posted: 07 Jun 2022 02:24 PM PDT I constantly see "anti-inflammatory properties" listed as a health benefit of various nutrients in healthy foods, but my understanding is that inflammation is a natural process of the human body. So anti-inflammatory foods are basically inhibiting a normal biological process. Why do we need to do that to be healthy? Why do we have a self-destructive inflammatory behavior in the human body anyway? [link] [comments] |

| If the human brain is oxygen deprived for even 10 minutes it's very dangerous. Why? Posted: 07 Jun 2022 08:41 PM PDT You'd think that it would take a few hours or anything more than just 10 minutes for human brain to get severely affected. But even 10 minutes of heart failure and lack of oxygen to brain is devastating. Why? It just sounds so baffling.... is everything in our body like that [link] [comments] |
| How do we determine and measure the average temperature of Earth? Posted: 07 Jun 2022 07:33 AM PDT I assume that the average temperature of Earth changes based on multiple variables: Distance from the sea/ocean, altitude, hours of daylight, time of day etc. What are the criteria for measuring the average temperature of Earth? I also assume that each nation gives their own averages, but how do we determine the weights for each country? For example Russia is a lot bigger than Luxembourg, so Russia should have more variation in temperatures and their landmass should represent a larger proportion of the average temperatures.

| If a child donates a kidney, will it continue to grow in the recipient’s body? Posted: 07 Jun 2022 01:21 AM PDT For context I'm watching House, which obviously as a TV show is not a 100% accurate medical resource, but in it a man needs a new kidney and gets it donated by his teenage daughter. They make a joke about him having a small kidney meaning he won't have to pee as much, which made me wonder if and why it wouldn't continue to grow to full size once transplanted. [link] [comments] |
| Where are there examples of wheels in nature/living beings, or even in some nonliving process? Posted: 07 Jun 2022 04:48 AM PDT The closest thing I can think of might be the femur in the hip bone, using Google/Oxford's definition: <a circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move [easily over the ground]>. There has to be something more wheel like! Maybe used in movement in a type of aquatic organism? What about in plants at any capacity? Where are all the nonhuman wheels? [link] [comments] |
| How soon after our last memory do we fall asleep? Posted: 07 Jun 2022 12:49 AM PDT I can never quite remember at what point I fall asleep. Is there a certain point after the last memory I have from the night before where I'm asleep [link] [comments] |
| Polymers and Plastics, are these deratives in the production of Petroleum? Posted: 07 Jun 2022 02:22 AM PDT I have this noob question because yesterday I voiced my opinion in saying polyesters like in my jackets are a by-product result in the production of car fuels. The opposing party stated that it is within its own production proces, these fabric producing companies just buy crude oil for manufacturing their products. Who can shed a light on this matter for me? [link] [comments] |
| Are lobsters more closely related to crabs or shrimp? Posted: 06 Jun 2022 10:43 PM PDT Keeping aquariums, including crawfish, shrimp, and crabs, I have obviously noticed that crawfish visually look a lot more like a shrimp than the average crab. In fact, at the store I work at, it takes a trained eye to distinguish between young crawfish and shrimp. I am assuming much of this applies to young lobsters as well, though all the ones I've seen have more distinguishable claws from an early age. Anyways, I am trying to understand oceanic evolution through time and I've read that decapoda evolved into reptantia (lobsters and crabs) and natantia (shrimp). Does this suggest that lobsters are more closely related to crabs than shrimp, or am I misunderstanding something? [link] [comments] |

| Is it known how many times has life spontaneously appeared in earth? Posted: 06 Jun 2022 10:03 PM PDT Pretty much the title … are all life forms on earth descendant of one single ancestor? Or has life appeared multiple times? [link] [comments] |
| How are valves within rocket engines 'turned'? Posted: 07 Jun 2022 02:22 AM PDT A diagram of an RS - 25 rocket engine showcased valves that allow the flow of the main fuel, main oxidizer, pre-burner, and chamber coolant. How are these valves 'turned' within the rocket engine? [link] [comments] |
