- Are boiling points and melting points affected by isotopic value?
- In historical,natural climate change, what caused temperature to drop after a while? Will this happen again with human caused climate change?
- Why does it hurt when disinfectant is applied to wounds?
- Are amazon fires actually at normal rate from previous years?
- Could the gas giant planets ever dissipate?
- Why did we create the equator? (interested in equator experts)
- Why is it that, at a younger age, we can get away with eating unhealthily yet still have so much energy, but, at an older age, you can feel the negative effects of unhealthy eating pretty quickly? Is there a biological reason?
- Is there a name for the actual origin of the wind, like how a river has headwaters?
- Do ants communicate when they find food?
- Do earthquakes make soil more nutrient rich from moving soil that's underground around?
- How will the heat from the burning Amazon affect weather elsewhere?
| Posted: 27 Aug 2019 04:00 AM PDT Hi, I'm Guy Leschziner, neurologist, sleep physician, and author of "The Nocturnal Brain: Nightmares, Neuroscience and the Secret World of Sleep". In this book, I take you on a tour of the weird, wonderful, and occasionally terrifying world of sleep disorders - conditions like insomnia, sleepwalking, acting out dreams, narcolepsy, restless legs syndrome or mis-timed circadian clocks. Some of these conditions are incredibly rare, others extremely common, but all of these disorders tell us something about ourselves - how our brains regulate our sleep, what sleep does for the brain, and why we all to some extent experience unusual phenomena in sleep. You can find out some more at
I'll be on at 11am ET (15 UT), AMA! [link] [comments]  |
| Are boiling points and melting points affected by isotopic value? Posted: 27 Aug 2019 03:31 AM PDT I know that these state change points are dependent on bonds between them but i was just wondering, is it only dependent on the electrons for their bonds or do the neutrons affect it. Such as water, if the elements in it were different isotopes such as hydrogen with a neutron and O-18 would this change the boiling point from 100 celcius or have no affect? [link] [comments]  |
| Posted: 27 Aug 2019 05:10 AM PDT So historically, the earths climate has gone trough various cycles of hot periods and cold periods. I know that this time is different, but I was wondering what exactly caused the climate to cool again after a hot period? I know that there are 'breakaway' climate change triggers and was wondering how those were reserved in the ancient past. [link] [comments]  |

| Are amazon fires actually at normal rate from previous years? Posted: 26 Aug 2019 08:52 AM PDT I've started to see severals people saying that amazon fires are actually happening at normal rates or even lower than previous years like 2005. The graph that is used is the one that is in globalfiredata site: https://www.globalfiredata.org/forecast.html#amazonas Now, I understand that fire count is different that fire sizes but is this fire actually worse that the situation we had in 2005 during Lula presidency? Every time I try to look about new-sources about this fire the only thing I can found is that "Is 84% higher than previos year" without going further. https://www.bbc.com/news/world-latin-america-49415973 Is the situation actually worse that the situation we had previous years? And why Also about deforestation rates: The "peak" were in previous years. Why is the situation actually worse now? Thanks! [link] [comments]  |

| Why did we create the equator? (interested in equator experts) Posted: 26 Aug 2019 05:36 PM PDT Helping to develop a series on the power of invisible things, and the equator is going to be a big part of the show, so i was wondering what i should know about the equator and specifically who the experts on the subject are? how have we determined the importance of an invisible line that exists only to us?

| Do ants communicate when they find food? Posted: 26 Aug 2019 02:33 AM PDT We are doing an experiment regarding communication between ants. In the experiment we plan to have two tubes, where one of tubes has a lump of sugar at the end of it and the other tube is empty. Our hypothesis for this is that the ants in the tube with the sugar in it would communicate with each other that there is food at the end of the tube and go faster to the end of the tube. Our main problem is that how can we prove that if they go faster, that it is because they communicated and not because of some different factor? [link] [comments]  |
| Do earthquakes make soil more nutrient rich from moving soil that's underground around? Posted: 26 Aug 2019 12:35 AM PDT Living in Japan it's easy to find fruits like grapes that are massive, among other fruits too. They're expensive because of the growing methods but I was wondering if earthquakes help refresh soils nutrients allowing them to reach large sizes. [link] [comments]  |
