| Posted: 10 Mar 2018 01:14 AM PST I was recently reading an article about De Beers fighting Chinese lab-grown diamonds that are basically indistinguishable from real diamonds. Are the two atomically identical? Without getting too philosophical, is a structurally identical lab-grown diamond a real diamond? [link] [comments]  |
| Posted: 09 Mar 2018 03:13 PM PST If I remember correctly, antlers are made of living bone, which means they have the ability to grow specific nodes(?), like on the femur. I also know that plants form shoots and branches via apical meristems and axillary buds. On a cellular level, how do antlers grow in order to form their complex branching structures?

| How much material will the MIT Fusion Reactor use, and how much waste will it produce? Posted: 09 Mar 2018 03:54 PM PST Science: https://gizmodo.com/mit-receives-millions-to-build-fusion-power-plant-withi-1823644634 How much water and lithium would the described reactor use, and how much helium would be produced? What if this were scaled up to replace all power plants worldwide? Thanks. [link] [comments]  |

| Posted: 10 Mar 2018 01:05 AM PST In humans when we get fungi infections such as thrush or athletes foot, we treat it with antifungal medicines such as Clotrimazole. Is there a risk that we end up with fungi spores that are resistant to fungicide or antifungal medicines? [link] [comments]  |

| Are there any practical applications for Fluoroantimonic acid? Posted: 10 Mar 2018 02:06 AM PST Just on a whim I looked up "strongest acid" and this popped up, but under applications it doesn't really say anything, well nothing meaningful to me anyhow. What is this used for? Does it just exist as a chemical novelty? [link] [comments]  |
| How do we know what the Earths core is made of? Posted: 09 Mar 2018 02:22 PM PST So this is one of my buddies that I love to death but I want to smack all the time. He's one of those conspiracy people who thinks nasa is fake, ALL pictures from space are fake, Elon Musk didn't launch a rocket with a car on it (despite video evidence before and after the launch) and he thinks scientists a lying about what our Earths core is made of. Good science people help me shut up my friend with facts and infallible logic I beseech you. [link] [comments]  |

| What is the information paradox? Posted: 09 Mar 2018 11:11 AM PST I heard it mentioned by kurzgesagt in his recent video on string theory but I am wondering if anyone can put it in layman's terms for me. [link] [comments]  |
| How do electrons behave at the interface between a superconducting and non-superconducting material? Posted: 09 Mar 2018 06:08 PM PST Suppose a superconducting wire is attached to the end of a conventional conductor and the entire set up is cooled enough to reach a superconducting state. If a voltage is applied across the wire, how do electrons interact at the boundary between the superconducting and conventional conducting materials? [link] [comments]  |

| What does oxygen look like coming out of plants? Posted: 09 Mar 2018 09:42 PM PST If there was a camera that could see the oxygen being produced by plants (like a thermal camera), what would that process look like? Is it excreted out of the leaves? Is CO2 soaked in from the leaved and pumped out of the ground? [link] [comments]  |

| Has dark energy always existed? Posted: 09 Mar 2018 11:15 AM PST (Degree in physics here, but from a long time ago.) Given that the universe expanded very quickly during the big bang, and given that its current expansion appears to be accelerating (hence we believe dark energy must exist) how is it that the universe is currently expanding more slowly than during the big bang? Was there a time during which dark energy didn't exist or didn't have the same effect, allowing the expansion to slow? [link] [comments]  |
| Why is priapism common in sickle cell anemia? Posted: 09 Mar 2018 01:40 PM PST I've heard that priapism is common in sickle cell anemia patients. Why are sickle cell patients predisposed to this? What are the causes? Biologically, what's happening? [link] [comments]  |
