| We are on the way to growing human organs, is making human blood feasible in a lab? Posted: 09 Mar 2019 10:04 PM PST If we could make blood in a lab, it wouldn't be potentially a carrier of disease from it's donor. Also, it would reduce the need for donors if we could just create it. If we are so close to creating organs that could be used for transplants, could we somehow also make different types of blood?

| Where and how can boron be obtained other than by refining on Earth? Posted: 10 Mar 2019 08:08 AM PDT I'm working on a fairly hard science fiction story in which proton-boron fusion is the main source of power. I've been looking all over the 'net for extraplanetary sources of boron, but I haven't found anything useful. Is there boron that could be mined from asteroids? Could it be manufactured in particle accelerators? Are there other viable sources? [link] [comments]  |
| Posted: 10 Mar 2019 05:11 AM PDT In the PP1 Chain when 2 protons fuse to make deuterium the energy released is 0.4 MeV. The binding energy of deuterium however is 2.2 Mev. Why do these two values differ? I thought the energy released was the same as the mass defect and hence the binding energy? What am i missing? [link] [comments]  |
| How can acyl chlorides be so reactive and have a strong C=O bond? Posted: 10 Mar 2019 07:03 AM PDT I'm really confused by the fact that in IR-spectroscopy acyl-chlorides have high wavenumbers for their C=O vibration, which means they have a strong C=O bond. Then why are they so reactive compared to other carbonyl derivates? Is the effect on the C=O bond overshadowed by the fact that f.e. chloride is a good leaving group? Are there any other reasons?

| Why do so many species have a rare chance of producing an albino “version”? Posted: 09 Mar 2019 10:33 PM PST What I meant was why is it so common that so many different species are able to produce a rare albino version. Like do they all share a specific gene that changes? [link] [comments]  |

| What stops all animals continuing to grow larger once they reach adulthood? Posted: 10 Mar 2019 08:31 AM PDT Plants and trees grow until their nutrient source is removed- so why doesn't this happen to humans and other animals? [link] [comments]  |
| Posted: 09 Mar 2019 09:41 PM PST Sort of like the speed of light. No matter how good our propulsion technology gets, we will never get anything to travel faster than light. Even all those dubious "realistic" possibilities like space-warping or wormholes are just workarounds, the actual object never traverses space faster than light. Similarly, is there a maximum amount of information you can transmit per second, regardless of how good our computing technology gets? [link] [comments]  |

| Posted: 10 Mar 2019 05:32 AM PDT I am wondering if it's still safe to consume. Long story short, I left my reactine in the car for a week when the weather outside was -15 c. [link] [comments]  |
| Will vacuum decay happen? Is there strong evidence supporting its existence? Posted: 09 Mar 2019 09:31 PM PST Is there anyway for the possibility of vacuum decay happening to be disproven? Going through a really bad existential crisis and need answers plz lol [link] [comments]  |
| Is there a radiation risk standing next to an unexploded nuclear weapon? Posted: 09 Mar 2019 08:52 PM PST How much radiation could someone detect next to an unexploded nuclear weapon? also what type of radiation is it? [link] [comments]  |

| How does the body know when to make blood and how does this blood get made? Posted: 09 Mar 2019 03:12 PM PST Lets say you donate blood, you loose a substantial amount of blood. How does your body know to start making more blood and where does this blood come from? Also, how does the body know when it has enough blood? [link] [comments]  |

| Posted: 09 Mar 2019 07:45 AM PST My understanding of glass was that it was that its a noncrystaline solid. Which right off the bat is confusing because theres something called "crystal glass". But in addition, I was looking at [wikipedia](&) about glass ceramics, which have both crystal and crystal aspects. In particular:
So it sounds like if you melt down a bunch of stuff and mix it together, it will cool down and become glass. But then they heat it up again and cool it down again, and it becomes crystal. I dont get how that works. They mention "nucleation agents", but also say "in most cases", implying its not always required. What exactly is a glass and what causes it to be that way?

| How likely is it for the Western Interior Sea to resurface? Posted: 09 Mar 2019 04:03 PM PST With the climate trending towards warming temperatures and the ice caps melting, what is the likely hood of the Western Interior Sea to refill the parts of the North American Continent it used to cover and what environmental consequences would that result in? Also if the Interior Sea were to refill for a lack of a better term, how long would that take assuming current trends continue? [link] [comments]  |
