How does light "bounce off" a material? Posted: 25 Sep 2018 01:17 PM PDT I understand that when light hits a surface, some light is absorbed (by exciting electrons), and other light is reflected, and it's that reflected light that gives objects their colors. What I don't understand is how atoms/molecules actually "reflect" light? If the light cannot interact with a material, I would expect it to pass through, but this only happens with transparent materials. How do photons bounce off an atom, and what determines whether they bounce off or pass through? submitted by /u/arbitrarycivilian [link] [comments]

Is body fat percentage correlated with how long someone can endure starvation before death? Posted: 25 Sep 2018 11:06 AM PDT Let's say two people wash up on a deserted island. One with 7% body fat and one with 32% body fat. They have access to a reliable water source however there is no food on the island. Would the individual with a higher body fat percentage be able to survive through starvation longer than the other? Logically I would assume that because there is more energy stored and available for use they would survive longer, however I've not seen any meaningful data supporting that notion. submitted by /u/gravyboat15 [link] [comments]

What could have caused a violent reaction between 2 store-bought pool chlorine brands? Posted: 25 Sep 2018 04:40 AM PDT A Tale of Two Chlorines ​ Can someone please explain why I had a sturdy plastic bucket literally explode into fragments when I mixed 2 different brands of pool chlorine together? I've never seen something explode like that when exposed to open air. So what I would normally do is mix the chlorine with pool water and then pour everything into the pool, no problem. One day we switched chlorine brands, so I poured the last little bit of the original chlorine into the bucket (there might have been a little water in the bucket to begin with) and topped up with the new chlorine. I noticed vapor coming off the mixture almost immediately as I started mixing. The reaction started bubbling and boiling and within about 10 seconds, the mixture started putting out a thick yellow cloud. This was when I knew I had to GTFO, mainly to avoid breathing in any of the noxious fumes. I can't quite remember if I was going to call someone or to get water to dilute the mixture. I turned around and started walking and as I turned a corner about 5 meters away from where the bucket was left standing, I heard an incredibly loud bang and saw pieces of the red bucket fly past me and land in the pool and on the lawn over 10 meters away. There was literally nothing left at ground zero other than a few white stains from the powder. It was a really powerful explosion. ​ This happened quite some years ago when I used to look after the pool at home, so the details may be a bit sketchy. I've always thought about that incident, what if I hadn't moved away? I could have been permanently blinded, or developed some kind of respiratory issue, possibly even hearing damage? ​ P.S. the brands were HTH and Clarity in that order (i think) There was no outside contamination that I know of. ​ Edit: Thanks for the replies and explanations so far. I'm glad I'm not the only one surprised/confused by this. Just a couple things, This was a long time ago like I said, so it might not have bubbled for 10 seconds, the gas might have been green instead of yellow, etc. All I know for sure is that it was loud, it started raining red plastic bits, there was definitely no lid on the bucket and that there were 2 brands of chlorine in a bucket. submitted by /u/PixelCortex [link] [comments]

How exactly is unused breast milk absorbed back into the bloodstream? Posted: 24 Sep 2018 05:56 PM PDT I read somewhere that whatever milk is left in the breast after weaning gets absorbed back into the body. But what exactly is happening there? How is the body able to absorb nutrients without involving the digestive tract? I hope these are not extraordinarily dumb questions. I only have middle school level background in biology (and most other things). submitted by /u/Massenstein [link] [comments]

In the quantum chemistry model why don't the negatively charged electrons fly into the positively charged nucleus? Posted: 25 Sep 2018 06:25 AM PDT In the Bohr-Rutherford model it makes sense why they wouldn't because it's just like why the planets in our solar system don't fly into the sun. But, in quantum chemistry you have stuff like P orbitals which look like 8's in which 1 electron is found in each loop so they dont rotate around the nucleus completely. Why don't they make contact with the nucleus? submitted by /u/Phobac07 [link] [comments]

I thought hydrogen and helium would create a nursery for new stars, but in the case of other molecules does a protostar form, or what happens next? submitted by /u/obsidianhoax [link] [comments]

If you have a family history of cancer, are you at risk for cancer in general or just the type of cancer(s) your relative(s) had? Posted: 24 Sep 2018 02:58 PM PDT So for instance, my aunt had breast cancer. As a male, my risk of getting breast cancer is still relatively low. However, does that also mean I am more likely to get any type? submitted by /u/Boba3964 [link] [comments]

When was the last time molten lava was naturally present on the surface in the continental USA? Posted: 24 Sep 2018 11:56 AM PDT I know the lower 48 states have lots of volcanoes, particularly on the west coast, and there have even been some relatively recent eruptions (most famously Mount St. Helens). But to my knowledge, those recent eruptions have been explosive gas and ash, not lava. The presence of massive ancient lava flows in states like Idaho and New Mexico indicate that volcanoes with lava do exist in these though. Basically, what I'm wanting to know is when the last time there was a Hawaiian-style eruption with flowing lava, and/or molten lava present on the surface, even if not part of a major eruption -- there's not a place like this in the continental USA currently, right? submitted by /u/xj20 [link] [comments]

Is a sound’s volume tied to its range? Posted: 24 Sep 2018 01:52 PM PDT In other words could you make something be heard from farther while maintaining the original volume.

In a galaxy, how much gas and dust would have to be present to prevent being about to see out of the galaxy in the visible spectrum? Posted: 25 Sep 2018 01:27 AM PDT As I understand it, we're unable to see across tongue other side of the Milky Way at least partially because there is too much gas and dust in the way. If the solar system were deeper into the galaxy where there's more dust and gas, or if the galaxy were less flat, could there ever be enough dust and gas to prevent us from seeing out of the galaxy entirely? submitted by /u/Lindvaettr [link] [comments]

How do various vitamins/minerals actually get used in our body?

What do we know about ancient gut microbiomes? Posted: 24 Sep 2018 07:47 AM PDT I know that we are just starting work on understanding the differences between gut microbiomes among modern populations.

Do we know anything at all about the gut microbiomes of Neanderthals? submitted by /u/Prufrock451 [link] [comments]

Would Outer Space be an effective coolant? Posted: 24 Sep 2018 09:20 PM PDT As opposed to something like nanofluids or liquid nitrogen, or even helium 3/4. I know that outer space is cold. (2.7K) But you also cant pump it around, and sometimes external radiation is a problem. I know the ISS uses radiators to get rid of its waste heat, but it doesn't have large reactor and doesn't use much power, let alone all that it uses. Basically, if you were going to put a ridiculously hot reactor on a giant space ship, would it make more sense to have outer space just cool it off for you than to use something else? What would be the advantage/disadvantages of using space to cool your reactor? submitted by /u/Poopallah [link] [comments]

Why is the polio vaccine still needed in the US? Posted: 24 Sep 2018 06:27 AM PDT Was doing some research and just want to understand. Polio is only transmitted through fecal matter getting into someone else mouth - either infected food, water, etc. Do we not have enough technological advances on food and water cleanliness that the vaccine is merely not needed any more? The only places that seem to still have polio (at a very low rate at that) are places where cleanliness can be hard to come by. Apparently the vaccine is only 95% effective, and 5% of people it is administered to will not be truly 'safe' from getting Polio, but still there are no reported cases in the Americas since 1991. Averaging 4 million births a year in the US from 1994 to now is 96 million people, 4.8 of which would not have the vaccine being effective. Still no cases. So why is the vaccine needed? ​ ​ submitted by /u/Theoneandonlyprizm [link] [comments]

AskScience AMA Series: I'm Alex Marson and I'm an immunologist at UCSF. My lab is building more efficient CRISPR-based gene editing tools to supercharge the human immune system to fight cancer, infectious disease, and autoimmunity. AMA! Posted: 24 Sep 2018 04:00 AM PDT Genetic engineering is now cheap, relatively simple, and pretty reliable - at least when done in a lab setting. Using a tool called CRISPR, researchers can access DNA in live cells, target specific strings of the DNA code to slice out, turn gene expression up or down, or even swap in new DNA. This means we can, theoretically, reverse genetic conditions, modify cell behaviors, and perhaps program the cells to better fight against disease. If you want an overview on CRISPR and how it works, my university created this animated explainer: https://youtu.be/iXgU--ugLqY My lab is using CRISPR to better understand how the genome controls the functions of human immune cells, in health and disease. We hope to use this research to inform future cell-based therapies to fight cancer, infectious disease, and autoimmunity. If you're deeply interested in CRISPR, you may have heard of our recent work - we discovered a way to make CRISPR more efficient and flexible in re-writing long DNA sequences in human immune cells, without the use of viruses. There are currently FDA approved gene engineered T cell therapies for certain types of cancer. These cells have been generated by using modified viruses to deliver genes into haphazard sites in the T cell genomes. Improved non-viral CRISPR delivery allows us, effectively, to paste long new stretches of DNA sequences into specific sites in the genome, without having to rely viruses that are costly and laborious to employ. We are working to develop non-viral CRISPR-based genome targeting into broadly useful platforms to make better, faster, cheaper engineered T cells for the next generation of immunotherapies. You can read my university's story about it here: http://tiny.ucsf.edu/OccPKL I'm here to talk about all things CRISPR, genetic engineering, immunology, or any other part of my work.

What was ocean weather like when Pangea was all together? Posted: 23 Sep 2018 01:46 PM PDT Hearing/reading about the effects of climate change on ocean climate got me thinking about the ocean climate in other geologic period. How would tides have been different? Would they have been bigger? Ocean currents, how would they have been affected with all that open ocean? What about storms like hurricanes? Would they have been super huge? I know that's a lot of separate questions. submitted by /u/camthomas96 [link] [comments]

Can you estimate the temperature at a certain depth as a function of the planet's radius? Posted: 24 Sep 2018 06:39 AM PDT On Earth, as you dig deeper and deeper into the ground, the temperature increases. Let's say we have another, reasonably Earth-like planet. Could we determine the rate of this increase purely based on the planet's radius? Would the temperature rise slower on a larger planet? I am specifically interested in the topmost layers of the planet (where one would reasonably dig a mine or drill or such). I'm not asking about the temperature deep in the core. Also, just a good order-of-magnitude estimate is enough, I understand that specific numbers would likely depend on many factors such as the planet's composition and so on. Thanks for replies! submitted by /u/Abdiel_Kavash [link] [comments]

Is the Uncertainty Principle due to the fact scientists do not know enough, or is it genuine chaos? Posted: 23 Sep 2018 02:28 PM PDT We learn in Chem 101 that the electron's location is unpredictable and they define this like a law. I'm wondering if theoretical physics, which dives deeper into subatomic particles, has a better understanding. Or, if new discoveries might be made to give a better understanding? submitted by /u/band_in_DC [link] [comments]

Why does regular soap make bubbles, but modern detergents don't? Posted: 23 Sep 2018 04:32 PM PDT I think I've got a good idea how soaps work, and the way they surround oily dirt in a layer of soap molecules to wash it away seems related to how they form double-layers in the wall of a soap bubble. So I'm not surprised that soap cleans and also makes bubbles. But specially-made detergents for washing machines and dishwashers clean *without* making bubbles. It makes sense that you'd design them that way, if the machine fills up with suds it won't work properly, but chemically, what's the difference between these detergents and regular sudsy soap? submitted by /u/agate_ [link] [comments]

Does Alzheimer‘s affect peoples dreams? How? Posted: 23 Sep 2018 02:24 PM PDT A loved one of mine would always say he thought he was dreaming even though he was awake. It led me to believe that in his dreams he was able to live normally while in the physical world it was more of a nightmare since he couldn't get a grasp of his surroundings. Could it be possible that people suffering from Alzheimer's are temporarily 'cured' in their sleep and that's why some believe they are asleep while they are awake? submitted by /u/fluffyllamapajamas [link] [comments]

Can focusing more light on a photovoltaic cell increase it's energy output? Posted: 23 Sep 2018 11:45 AM PDT I have seen several systems that claim to collect 5x or 10x the electricity from photovoltaic cells by using lenses to project more light onto the cell. Is there data that shows this is possible? Also, the heat should eventually decrease the efficiency of the cell, so at what point does that happen and does it negate the gain (if any) achieved using the focused light? submitted by /u/CamReadit [link] [comments]

How do you determine the number of bonding orbitals in a single atom? Posted: 23 Sep 2018 03:44 PM PDT I read that fluorine has a 2s orbital and a 2p orbital available; yet, bromine has only a 4p orbital. Both atoms have the same number of valence electrons. Could it have something to do with the 3d orbital in bromine? thanks. ​ submitted by /u/BirdAcid [link] [comments]
