| What can we use bronze for today and why? Posted: 17 Sep 2018 11:59 PM PDT I was wondering what we use bronze for today and the reason for it. I cant seem to find a reason for using bronze in industrial and non-industrial purposes. [link] [comments]  |
| To what extent does the pre-frontal cortex continue its development between the ages of 18-25? Posted: 17 Sep 2018 09:42 PM PDT If the PFC is not fully mature until a person's mid 20's, how much change is actually occurring from post-puberty to then? I understand that further myelination or synaptic pruning in this region would alter it. However, is the overall development slowly coming to an end as a person ages? Or, is significant change still happening during those 7 years that can be observed? [link] [comments]  |
| Posted: 17 Sep 2018 05:22 PM PDT Does there have to be some trade-off between voltage (increase) and amperage (decrease) to maintain the same power? Is this possible? What characteristic determines how the electricity is manipulated to have different properties coming out than it did coming in? [link] [comments]  |
| 1 Why do pressed/dried leaves retain most of their bright colors instead of turning brown? Posted: 17 Sep 2018 11:05 PM PDT I pick an especially colorful leaf each year to save from Autumn/Fall and they've always stayed the same color once dry. Why do leaves keep their "autumn" patterns and colors if you put them between book pages or dry them upside-down, and not just die and turn brown? Why do all the leaves on the ground die and turn grey/brown before winter? Bacteria? [link] [comments]  |
| What physically happens to the body in a morphine overdose? Posted: 17 Sep 2018 07:07 PM PDT I know that its used in regulation to negate pain but what physically happens to a body when a large amount of morphine is given to kill someone. [link] [comments]  |
| Is Dwarfism immediately recognizable at birth? Posted: 17 Sep 2018 06:57 PM PDT Can doctors immediately recognize an infant has dwarfism when it's born or does it take a while to begin to see the signs? [link] [comments]  |
| How do stars create extremely heavy elements after uranium? Posted: 17 Sep 2018 04:16 PM PDT I know that supernovas can create extremely heavy elements (up to uranium as far as I know), but how are the elements after that formed? [link] [comments]  |
| How did scientists recreate the 1918 Influenza Virus? Posted: 17 Sep 2018 01:50 PM PDT I do not know if I've used the right flair, but the articles have put heavy emphasis on evolutionary biologists, so I figured this was a biology question. I've been doing some research into the 1918 Influenza, and I've seen all sorts of stuff about the historical impact of the virus, but not a lot about the biological properties of the virus itself. Some articles seem to suggest it was the H1N1 virus, while others say the H1N1 virus is a "distant relative" of the Spanish Influenza. I have also read comparisons to the H1N1 and H5N1 viruses made by recreating the Spanish Influenza virus. Which leads me to my question - how did scientists recreate the Spanish Influenza virus? And is it the H1N1 virus? Or just a similar virus? Thanks! [link] [comments]  |

| What's the reason behind countries choosing different voltage standards? Posted: 17 Sep 2018 10:35 AM PDT For example, USA has 110/120 V while UK/India has 220/240 V. Is it a deliberate choice? or an after-effect of something else? Just realised that it is quite stark and was curious to know the reason. Let me know if this is not a good enough question [link] [comments]  |
| Does eating lactose while lactose intolerant have cumulative negative effects? Posted: 17 Sep 2018 07:32 AM PDT Does the intolerance have long term effects, if the immediate symptoms are ignored? [link] [comments]  |
| Posted: 17 Sep 2018 07:41 PM PDT I remember watching a reading rainbow where Levar Burton wore special glasses and talked about how your brain switched things around. I think it was reading rainbow. The audio channels were switched on a game I was playing and I wondered if the same would happen eventually. I assume it would require more controlled conditions if it was even possible. Edit: Ugh I messed up the title but I think you know what I mean. [link] [comments]  |
| Posted: 17 Sep 2018 03:34 PM PDT Reading on Wikipedia, I see there are particles arriving Earth with an energy of 100 EeV (about 16J, about the same energy as a mid powered air rifle) with a frequency of 1 event per square meter per century. Apparently, there are recorded events that reach 50J, equivalent of a baseball at 90 km/h (56 mph). I understand that on the surface it arrives scattered as secondary radiation after hitting the atmospheric gasses, so there wouldn't much to notice, except for equipment to measure this sort of events. But what would happen when an astronaut during an EVA (extra vehicular activity) happened to be hit by one of such particles? Would it be closer to radiation poisoning or to actually being hit by an object? [link] [comments]  |
| How exactly does a smart meter know the difference between TV usage, AC usage and other? Posted: 17 Sep 2018 11:09 AM PDT My utility bill shows me a chart of energy usage based on device (AC, refrigerator, Always on and other). I'm curious how it can know what devices are using electricity and how accurate the information on my bill is. [link] [comments]  |
| Why is HIV /AIDS more prevalent among LGBTQ community? Posted: 17 Sep 2018 11:23 PM PDT I hope this is the appropriate sub for this question. [link] [comments]  |
| Posted: 17 Sep 2018 05:54 AM PDT Does anyone know the statistics for certain drugs for multiple countries - for example medicine "A" has a 1 in 20 person usage rate in UK vs 1 in 11 for the USA? Are people more likely to be prescribed something in a country with subsidized medicine or without? [link] [comments]  |
