| Posted: 01 Nov 2019 04:00 AM PDT We are from the Society for Research on Biological Rhythms (SRBR), an organization of international scientists, clinicians, and industry experts who promote basic and applied research in all aspects of biological rhythms. We are dedicated to advancing rigorous, peer-reviewed science and evidence-based policies related to sleep and circadian biology. Daylight saving time (DST) in the USA ends this weekend and we support the campaign to permanently end DST for better health. You can read more about this in our position paper titled "Why Should We Abolish Daylight Saving Time?" that was published in the Journal of Biological Rhythms earlier this year. Our team for today is:
You can also find us on Twitter at @SRBR_Outreach. We will be online at 3pm ET (19 UT) on Friday November 1st to answer your questions. Ask us anything! [link] [comments]  |
| when in colonies, how do bats use echolocation without getting confused? Posted: 31 Oct 2019 05:05 PM PDT I recently visited a location in Austin, Texas in which 100,000 bats live under a bridge. I could hear all of them squeaking at the same time but was wondering how they can use their echolocation without being confused by other bats squeaks. is there a way they can find their own squeak? It seems comparable to trying to distinguish someone's voice in a room full of people talking, but maybe echolocation works completely different. thank you :) [link] [comments]  |

| Posted: 01 Nov 2019 12:02 AM PDT Hi, I saw this post on the front page of a millipede walking and saw that it has a pretty much constant wavelength to the motion of his legs. I was wondering why would it use that specific one? Does it depend on length or number of legs? Do all millipedes use the same wavelength? Would using a shorter one mean walking faster? Thanks!

| How Exactly Does Prion Disease Kill? Posted: 31 Oct 2019 03:18 PM PDT My friends and I were talking about cannibalism the other day and Kuru came up. I've looked around and haven't found anything that plainly states how exactly the disease kills. Same with Mad Cow. I know prion disease is the prion converting normal proteins into prions but why exactly is that lethal? What does that do? [link] [comments]  |

| What makes an electron or proton negatively or positively charged? What defines that? Posted: 31 Oct 2019 02:24 PM PDT I just had science class today, and we are talking about the inner workings of atoms, and I couldn't get this question out of my head. [link] [comments]  |
| Why do you float to the surface despite when deep in the sea there is a great pressure on you? Posted: 31 Oct 2019 05:53 PM PDT |
| How did the southern United States accent come to be? Posted: 31 Oct 2019 12:17 PM PDT The southern accent in the United States is very distinctive. How did it come to exist, and for that matter any of the other strong regional accents, like New York and Boston? [link] [comments]  |
| Why does a standing wave appear in this rope? Posted: 31 Oct 2019 05:39 PM PDT It appears not the be the Mould effect, and is different than the fountain effect. rope standing wave Especially towards the end of the video [link] [comments]  |
| How have fish adapted to fishing? Posted: 31 Oct 2019 12:51 PM PDT Is there any evidence of selection for those who don't eat certain bait? Maybe they're more skiddish? [link] [comments]  |
| Do all parts of a super fast rotating star go at the same speed? Posted: 31 Oct 2019 03:07 PM PDT So I was just reading about a star that rotates at 25% the speed of light. That has me wondering, how does the whole star go that speed? Since stars are a "fluid" do they obey traditional fluid dynamics where the equator goes faster than the poles and that's what we're able to measure? Alternatively, due to the super strong magnetic fields, that forces the whole mass to go the same speed? Bonus: How do we measure the rotation of an object that far away? [link] [comments]  |
| Is anything described by the Schrodinger equation besides quantum mechanics? Posted: 31 Oct 2019 05:44 PM PDT The wave equation shows up in a zillion different places. So does the heat equation. Try finding something that spring equations aren't useful for approximating. Same for almost everything I learned in my physics degree, with the conspicuous absence of the Schrodinger equation, but I'd expect that's just my ignorance showing. Are there any neat examples of systems outside QM that can be described by the Schrodinger equation? Or other things that can be quantized in analogous ways? edit: I should say I'm curious about applications outside of physics, like how heat and wave equations show up in places like traffic and population dynamics and stock market modeling, and even hamiltonian dynamics aren't limited to being useful only for physical systems.

| How abrupt was the average temperature change that occurred in the younger Dryas? Posted: 31 Oct 2019 12:21 PM PDT I'm finding lots of different claims on this: some say it was rather gradual and happened at a few tenths of a degree/century, other sources I've found state that the YD actually started and ended very suddenly, to a rate that is very much comparable to that of the current anthropogenic global warming (one whole degree in just a few decades). What does the science say? Would a detailed century-to-century graph of the average temperature in that period show a gradual curve? Or would it show a sudden (almost vertical) drop, then a more or less stable period and eventually a just as sudden rise? [link] [comments]  |
| [Medicine] Why do mechanically stressed podocytes have increased glucose uptake? Posted: 31 Oct 2019 05:15 PM PDT I'm having a hard time explaining this line: "In mechanically stressed podocytes, glucose uptake increased 2-fold in the LG and NG groups but increased 3-fold in the HG group." Why does this happen? Or does further research need to be done to understand this mechanism [link] [comments]  |
| How do engineers determine whether a major fault occurred when dealing with destroyed mechanics? Posted: 31 Oct 2019 09:36 AM PDT If an engine, for example, is completely destroyed, what's the process to determine if it suffered a fault? [link] [comments]  |

| Does the body adapt hearing based on the environment? Posted: 31 Oct 2019 02:03 PM PDT Say I normally listen to my TV with volume on 30. I sounds clear and not too high that it bothers. Then a storm comes and I have to turn it up to 70 to be able to barely listen. If i turned up to 70 on a quiet night, it would be uncomfortable and likely damage my audition a little bit. Is the sound of the TV damaging my hearing during the storm on 70, the same way than on a quiet night? Similar to when turning your headphones volume up caught up on traffic. [link] [comments]  |

| We have string theory than why are we still looking for the theory of everything? Posted: 31 Oct 2019 06:15 AM PDT |
| Why do some minerals have multiple crystal habits? Posted: 31 Oct 2019 07:32 AM PDT For example how can pyrite be cubic, but can also be dodecahedral and octahedral? Shouldn't it always be cubic? [link] [comments]  |
