| Why do quantities like brain-structure-mass-to-neuron ratio affect animal cognition? Posted: 04 Jun 2018 07:03 AM PDT Hi AskScience, I've been reading about Dr. Herculano-Houzel's brain soup method after following some popular science articles. It appears that in various brain structures, the mass-to-neuron ratio for primates deviates from other groups of mammals and presumably that is at least one factor which causes increased cognition (though I could be wrong, so please let me know if so!). Why should that be the case? As a side question, have any studies been done on other mammals such as whales and dolphins? A quick google search didn't yield anything in that realm. Thanks!

| Is WISE 1828+2650 habitable at all? Posted: 04 Jun 2018 08:17 AM PDT I just found out recently, via a temperature of the universe info graphic, that WISE 1828+2650 has an surface temp of 80F/27C. Is there a maintainable orbit where the radiant temp would be appropriate for human living conditions? What about the surface directly? Other than lack of oxygen, is there anything inherently toxic about the environment that would need to be overcome? [link] [comments]  |
| What is the density of dark matter? Posted: 04 Jun 2018 06:11 AM PDT I saw in book that the observed density of dark matter is round about 4 eV per KMH-Photon. What does KMH-Photon mean? Never saw that unit. Neather could I find any more information about the density of dark matter. How exact do we know the density? [link] [comments]  |

| Why does gold have a smaller atomic radius than lead? Posted: 03 Jun 2018 04:54 PM PDT So, just from a discussion, I was thinking about Gold being denser than lead, to which I figured it largely has to do with atomic radius and bond lengths. Now I could be wrong here, only having an advanced high school level understanding of chemistry, but I remember being taught that generally radius decreases across a period due to a stronger nuclear effect. Is this incorrect or is there something else at play here causing this? I assume this question occurs elsewhere on the table, but gold and lead were just the notable examples here.

| What happens to bullets shot straight up into the air? Posted: 03 Jun 2018 08:50 PM PDT Do they go up into space or eventually come back down? Where would they land? [link] [comments]  |
| What is the Structure at the Center of the Tevatron? Posted: 03 Jun 2018 06:37 PM PDT My understanding was that the beam only had functions around the outside of the circle. What is the purpose of the tower at the center of the Tevatron? I did some searching but was unable to find details on it. Not a great image but here's a link to maps. [link] [comments]  |
| How are proteins in our body powered? Posted: 03 Jun 2018 11:34 AM PDT I was watching this video by Veritasium and I'm mind-blown by the complexity. The proteins that move; How do they do it? What is making them move and how is the energy they use distributed to them? The proteins that create for example microtubules; How do they get the "building blocks" they use? [link] [comments]  |

| How does lightening "know" what it "wants" to hit? Posted: 03 Jun 2018 01:44 PM PDT From what I understand lightening hits things that offer the least resistance, but how does lightening know to hit those things? (Sorry to personify) When I was looking this is up the Internet kept saying things about positive lightening too, which I've never heard of. Please, someone explain the mystic workings of the Big Sky Fire to me. [link] [comments]  |
| Why can we see satellites orbiting the earth? Posted: 03 Jun 2018 10:36 AM PDT It doesn't seem like they would have bright lights on them. [link] [comments]  |
| Helium has a melting point of -272 degrees Celsius, and boiling point of -269: how is this possible? Posted: 03 Jun 2018 08:03 AM PDT Seems odd to me that a gas would have a melting and boiling point very close to each other, at a near extreme cold - how? [link] [comments]  |
| What is the smallest possible size of a nuclear fusion reactor? Posted: 03 Jun 2018 05:00 AM PDT Obviously it couldn't be the size of Tony Stark's Arc Reactor but how small could we make a nuclear fusion reactor, at least with modern technology? [link] [comments]  |
| Do CT scans increase the risk of cancer noticably? Posted: 03 Jun 2018 07:50 AM PDT Doctors often say not to do them unneccesarily due to the radiation involved, but is there a noteable increase in the risk of cancer after having one and if so how long does that increase stay noticable? Wasn't quite sure what to flair this as... [link] [comments]  |
| Why do they specifically swab your nose and groin when screening for MRSA? Posted: 03 Jun 2018 05:47 AM PDT What specifically about these areas makes them the place to swab, does MRSA have some affinity for the Nose/Groin? And if so, why? The two areas don't seem to share that much in the way of common characteristics. [link] [comments]  |
