How did dinosaurs have sex? Posted: 13 Sep 2018 02:03 AM PDT I've seen a lot of conflicting articles on this, particularly regarding the large theropods and sauropods... is there any recent insight on it. —— Edit, big thank you to the mods for keeping the comments on topic and the shitposting away. submitted by /u/JackhusChanhus [link] [comments]

Does lemons prevent the binding of caffeine & tannin in tea? Posted: 13 Sep 2018 01:44 AM PDT Hey, I've read that caffeine is more water-soluble than tannin. So short brewed tea has more free caffeine than long brewed. Long brewed has more caffeine in total but a lot of it has bond to tannin. Gastric acid is capable of splitting the bond so the caffeine will be bio available over a longer time span. This morning I put pure citric acid in my tea and I noticed that the tea looks a lot clearer and much lighter than my normal long brewed tea. Questions: Does the citric acid prevent the solution of tannin? Can citric acid prevent the binding of caffeine to tannin in the first place? How many slices of lemons would be needed to achieve that in a 200ml cup? -> Cultural reason for lemons in tea? Thanks for your answers :) ​ [EDIT] after nearly 8k views (haha I love the internet) I decided to make a short timelapse, because many of the auto deleted comments didn't believe that the tea looks different with citric acid. of course I missed the sweet-spot with the acid but trust me I can't drink anymore tea today. I'm nervous AF and I've got heartburn. https://youtu.be/YbnZabBx_Eo ​ submitted by /u/iNeverCouldGet [link] [comments]

How do sea creatures react to tropical storms? Posted: 12 Sep 2018 10:41 PM PDT I read this week that helicopters are detecting 80ft waves from the storms brewing this week! Isn't this disruptive for the beings swimming in that mess? Do they just swim somewhere else when they sense stuff is getting crazy or if they hang out deep enough in the water can they avoid being affected? Also, do tropical storms negatively affect any other sea life, like reefs or sea plants? submitted by /u/babaozhou [link] [comments]

How much did the Chicxulub crater affect the plate tectonics of North America? Posted: 13 Sep 2018 01:59 AM PDT Recently I've been curious about Pangea and how our current map was formed. When I watch videos or see drawings of the transformation of earth I don't ever seem to see any change due to the massive crater that wiped out the dinosaurs. However, we know there is a massive crater, so I'm just wondering if it caused any change in the drift of the plates. submitted by /u/LAKingsDave [link] [comments]

Is the large curve of coastline between Florida and the Carolinas in any way related to erosion from centuries of hurricanes?

Why do most test tubes lack a base that lets them stand on their own in favor of racks where they’re put into? Posted: 13 Sep 2018 06:29 AM PDT I've always thought this is weird, because it would probably be easier to work with if you didn't have to always put it back on the rack and could set it down wherever you are and would be in reach whenever needed instead of having to go back to a rack on the other side of the room. Is there a particular reason for this? submitted by /u/obie_the_dachshund [link] [comments]

How much energy is expended to deliver 1kW of power to a home from where it is generated? Posted: 13 Sep 2018 05:14 AM PDT Basically the title,but to add a few more thoughts: What's the energy loss in transfer? Can we calculate the energy used to produce the transport cabling, transformers, etc? What's the overall efficiency in supplying power from a plant far away versus one near by or perhaps even on site power(ie solar panels)? Thanks, submitted by /u/KK6AXQ [link] [comments]

Would it be theoretically possible for Earth to generate a permanent hurricane, similar to the red spot on Jupiter? Posted: 12 Sep 2018 12:44 PM PDT Florence's trajectories had me wondering. I'm assuming climate change would be the biggest factor in creating an environment that hostile but I don't have any facts on the topic. Edit to elaborate after clarification below: I guess my question is if climate change could get bad enough where we would start seeing these long form hurricanes lasting 1+ years? What types of conditions would be necessary for that to occur? 'Earth sciences' submitted by /u/bx002 [link] [comments]

What's wrong with this argument against evolution? Posted: 12 Sep 2018 04:17 PM PDT From a young-earth creationist's blog: The critical factor in evolutionary change is not actually time. Instead, it's population size and generational turnover. This is because the requirement is that substantial variability be provided (by population size) and many opportunities for selection to whittle down a generation and act on that variation. This is very important, because it means that what Darwinists claim we can't see, we actually can see. We can examine what occurs, given a certain amount of evolutionary resources. Malaria has existed on this planet for several millennia, and operates by invading hemoglobin, eating it from the inside out, and destroying it. Its structure is such that it can only survive in very warm climates, however. Given the enormous population of malaria across the planet and the rapid generational turnover- each infected person has billions of malarial organisms that multiply exponentially- malaria has the same evolutionary resources that any mammalian lineage has had since its descent from sponges in the Precambrian. Think about that. Malaria has never adapted to be able to live in a slightly cooler climate. Never. This is what is supposed to have created the human brain? I suspect there are some fallacies here, or misconceptions about evolution. How would you respond to this person? submitted by /u/kipling_sapling [link] [comments]

What is the temperature threshold for the release of hexavalent chromium from stainless alloys? Posted: 12 Sep 2018 05:21 AM PDT As per the OSHA safety sheet on hexavalent chromium, workers can be exposed to the toxic substance during "Welding and other types of "hot work" on stainless steel and other metals that contain chromium." I'm familiar with the fact that this is a thing, and with the health and safety risks, but I've been unable to dig up any specific tests or hard data as to what exactly the threshold for this is. Neither the materials from OSHA, EPA, and CDC, nor the few other papers I've dug up on google seem to provide an answer here... they all seem to be more oriented toward the various health concerns and the mechanisms behind them. ​ This is applicable to my daily life as a D17.1 aerospace TIG welder (and machinist), however what really sparked the question is that stainless steel wire is commonly used as a heating element in electronic cigarettes and I'm curious to know if there's a concern of hex-chrome exposure from that. submitted by /u/macthebearded [link] [comments]

In layman terms, what is the significance of transconductance?

Electrical conduction - How could you determine if there is a lot of free electrons flowing slowly or just a few flowing quickly? Posted: 12 Sep 2018 06:57 AM PDT Consider a straight wire of known length, cross-sectional area and resistivity. Applying a known voltage results in a known current.

Are double and triple bonds more stable or more reactive than single bonds? Posted: 12 Sep 2018 06:21 AM PDT I'm a high school student with some confusion regarding my chemistry classes. I remember my teacher explaining in one course that double and triple bonds are more stable than single bonds, however at the same time I've learned that double and triple bonds are also considered functional groups, which means that these will react with other compounds easier? To me it seems like these two statements kinda contradict each other?

If you put a hot object into space does it cool down and if so is it faster or slower than when the same hot object is in an atmosphere (of a lower temperature)? Posted: 12 Sep 2018 02:04 AM PDT Just curious but based upon my limited knowledge of temperature it is the magnitude of movement of atoms in a medium. If you put a hot object into a perfect vacuum there must be no means for the heat energy to transfer to the surrounding environment and therefore the object must remain at the same temperature forever. Is this correct? submitted by /u/HandgrenadeH [link] [comments]

How is louder sound different from soft sound? Posted: 11 Sep 2018 02:59 AM PDT Generally we say sound travels at the same speed in the air, regardless of amplitude. But in order for us to hear loud sounds, our eardrums must be pushed stronger.

Posted: 10 Sep 2018 08:34 PM PDT I know the obvious answers is solar and wind, but if you take in account production (especially photovoltaic cells) it takes quite some time for these form of energy production to be greenhouse gas neutral.I know nuclear power is carbon neutral, but considering how it admits water vapor it doesn't seem to be greenhouse gas neutral. From reading NOAA.gov and Wikipedia it seems that only oxygen and Nitrogen are considered to be non-greenhouse gasses.So what is a form of energy production that produces zero greenhouses gasses? From reading NOAA it seems that water vapor may be negligible. submitted by /u/sunal135 [link] [comments]

[Honest] Is there any science that explains how/if hypnosis works? And why it seems to work on some people and not others? Posted: 10 Sep 2018 07:51 PM PDT submitted by /u/SCWarriors44 [link] [comments]
