| Do pet tarantulas/Lizards/Turtles actually recognize their owner/have any connection with them? Posted: 05 Jan 2016 06:54 PM PST I saw a post with a guy's pet tarantula after it was finished molting and it made me wonder... Does he spider know it has an "owner" like a dog or a cat gets close with it's owner? I doubt, obviously it's to any of the same affect, but, I'm curious if the Spider (or a turtle/lizard, or a bird even) recognizes the Human in a positive light!? [link] [690 comments]  |
| What is this article claiming? Water has memory? Posted: 05 Jan 2016 06:38 AM PST A friend of mine, a PhD student in psychology, posted a link to this article and said "Finally proof that water has memory!" Not sure if she means in the homeopathic pseudoscience sense, but what is this article actually saying? I'm skeptical but I find the article fairly impenetrable. http://www.nature.com/ncomms/2015/150918/ncomms9384/full/ncomms9384.html It's in Nature Communications. Does that mean submitted without peer review? [link] [311 comments]  |

| How can it be determined if North Korea really detonated a Hydrogen bomb? Posted: 06 Jan 2016 04:03 AM PST Could it be measured as an increased content of certain isotopes in the atmosphere in the coming days/weeks? Further analysis of the seismic data? Emitted radiation? Other ways? Source: http://edition.cnn.com/2016/01/06/asia/north-korea-hydrogen-bomb-test/index.html [link] [9 comments]  |

| Why do the lights in my bathroom dim when I turn on my vacuum? Posted: 05 Jan 2016 09:25 AM PST (EDIT: Sorry if the flair is wrong. My ideal flair would be "Energy," but I wasn't sure if this would be "Physics" or "Engineering.") The obvious answer would be that the vacuum is taking in some of the power that would go to the lights, but I've been noticing something strange. First of all, the lights only dim momentarily before going back to their normal brightness. Second of all, the outlet I use for my vacuum is right outside my bathroom door, so my guess is that the lights and the outlet must be really close enough on the circuit for one to affect the other. But when we plug in the TV or a fan, the lights are unaffected. I can understand a fan because it probably doesn't use as much energy as a vacuum, but a TV? Third of all, I've noticed that this only happens for my bathroom. Whenever I plug the vacuum into the outlet outside my parents' bathroom (and the bathroom lights are on), when I turn on the vacuum, their lights are unaffected. What's going on here?

| Posted: 05 Jan 2016 06:30 AM PST I've heard the fact multiple times that honey will never go bad. If this is so, why is it true? What is special about honey as opposed to other food items? [link] [19 comments]  |
| How is hydrofluoric acid so dangerous but is still considered a weak acid? Posted: 05 Jan 2016 11:33 AM PST I understand that strong vs. weak acid classification is based on the amount that the compound disassociates in water. My question is - how can HF be so dangerous yet only disassociate 'weakly' in water? Why does it behave so differently from HCl, considering thow similar chemically Chlorine and Fluorine are? Thanks!

| How do scientists create pharmaceuticals when they dont understand their exact mechanism of action? Posted: 05 Jan 2016 03:17 AM PST Surely you would have to know how something is going to work before you engineer it to get the desired effect? There is an entire list of drugs where the mechanism's are unknown https://en.wikipedia.org/wiki/Category:Drugs_with_unknown_mechanisms_of_action [link] [5 comments]  |
