| Why do Flies behave the way they do around hanging light fittings? Posted: 07 Jul 2018 01:57 PM PDT With the hot weather, Flies inevitably end up coming through my open window and amassing around the light fitting in the centre of my living room, flying in a constant 4 or 5 point formation around the circumference of the light. Now I have seen this many times before but I have to ask... why do they do this? This light isn't on and doesn't even have bulbs in, but they are constantly drawn to it. Also, whats the little tussles they have with each other every few seconds or so? Are they fighting or is it some kind of reproductive thing? [link] [comments]  |

| How does reproducibility happen in very expensive experiments? Posted: 07 Jul 2018 06:11 PM PDT I've been addicted to PBS Space Time and just got done with the "sterile neutrino" episode. The host mentions that several very large laboratory experiments disagree on the results. That made me wonder: what happens when a claim is made that's the result of a very unique/expensive test result? I'm thinking along the lines of a particle accelerator or a test that's due to space probe data. Wouldn't these not be reproducible under the same conditions? For instance, if a sensor was malfunctioning in a space probe - and some conclusion was made from the results, how would they be falsified? Sorry for the long-winded question! [link] [comments]  |

| What's the Curie temperature of a CoPtCr alloy hard drives are usually made of? Posted: 07 Jul 2018 05:21 PM PDT I was reading a bit about computer forensics and I thought that one way of effectively deleting all the data from a mechanical hard drive would be heating it up to the Curie point of the magnetic medium in the platters, so that magnetic domains get all messed up and what is left is just random bits. At what temperature would that Curie point be? Would it be the max between the Curie temperature of Cobalt, Platinum and Chromium? Or the min? Or maybe (as I think to be the most likely) the fact that we're talking about an alloy changes everything? Thanks in advance to everyone who will spend their time answering this. [link] [comments]  |
| How does Explosive Trace Detector work? Posted: 08 Jul 2018 02:03 AM PDT In the some aeroports, when people get searched, the searching team has a piece of fabric that they run on the searched person's electronics, clothes, hair and inside their bags, then put into this machine which supposedly shows whether traces of explosives exist or not. How does this fabric keep the traces of explosives and not getting it mixed with anything else, and how is the machine able to check if those traces exist or not in matter of seconds? Does this machine do its job sufficiently? Or it's just another piece of time wasting procedures in the aeroport? Edit: I am not sure if this is engineering or chemistry, but I'll put it chemistry since I think it is closer... [link] [comments]  |

| How does VPN (Virtual Private Network) work? Posted: 07 Jul 2018 02:01 PM PDT At school and at work, certain websites can be blocked, but I and many friends have used VPN to gain access to sites that are blocked and I have always wondered how VPN is able to do this and potentially what else it is useful for.

| Posted: 07 Jul 2018 08:33 PM PDT I'm assuming other animals might have dug and eaten but still there's no seed to disperse. How and why did it even evolve in this way? Isn't it very disadvantageous for it? [link] [comments]  |

| What are the ethics of human testing in things like the new HIV vaccine? Posted: 07 Jul 2018 08:10 AM PDT Source in case you aren't familiar with the specific study I'm asking about. My question revolves around the ethics of human testing others, but mostly this case. How do you do human testing with something like HIV/AIDS, or anything without a cure. For example, if the vaccine doesn't work, or someone happens to have an unknown adverse reaction, and the person now has HIV. [link] [comments]  |
