We are scientists from the Society of Vertebrate Paleontology coming to you from our annual meeting — which is virtual this year! We study fossils. Ask Us Anything! Posted: 14 Oct 2020 04:00 AM PDT Hi /r/AskScience! We are members of the Society of Vertebrate Paleontology, here for our 7th annual AMA. We study fossil fish, mammals, amphibians, and reptiles — anything with a backbone! Our research includes how these organisms lived, how they were affected by environmental change like a changing climate, how they're related, and much more. You can follow us on Twitter @SVP_vertpaleo. Also, it's National Fossil Day in the US. Please join us in celebrating! Our experts today are: Matt Borths, Ph.D. (/u/Chapalmalania) is the Curator of Fossils at the Duke Lemur Center at Duke University in Durham, NC. His research focuses on the evolution of carnivorous mammals and primates, especially in Africa and North America. He is also part of several teams working to network natural history collections. Dr. Borths co-produced the paleontology podcast series Past Time (www.pasttime.org). Stephanie Drumheller, Ph.D. (/u/UglyFossils) is a paleontologist at the University of Tennessee whose research focuses on the processes of fossilization, evolution, and biology, of crocodiles and their relatives, including identifying bite marks on fossils. Find her on Twitter @UglyFossils. Eugenia Gold, Ph.D. (/u/DrEugeniaGold) is an Assistant Professorin the Biology Department at Suffolk University in Boston, MA. Her research focuses on the evolution of the brain in dinosaurs. Dr. Gold also created www.drneurosaurus.com and co-authored She Found Fossils (and Ella Encontró Fósiles), a children's book about women in paleontology. Josh Miller, Ph.D. (/u/PaleoJosh) is a paleoecologist and Assistant Professor at the University of Cincinnati. His research focuses on Pleistocene paleoecology, taphonomy, and using fossil and subfossil records to help conserve and manage modern ecosystems (Conservation Paleobiology). Find out more at JoshuaHMiller.com. Ali Nabavizadeh, Ph.D. (/u/vertpaleoama) an Assistant Professor of Anatomy in the Department of Biomedical Sciences at the University of Pennsylvania School of Veterinary Medicine. His research investigates the comparative anatomy and evolution of herbivorous dinosaurs, dicynodonts, and proboscideans. He is specifically interested in the muscles of their skulls and jaws, and the functional morphology of how they feed. Find him on Twitter: @Vert_Anatomist. Adam Pritchard, Ph.D. (/u/vertpaleoama) is the Assistant Curator of Paleontology at the Virginia Museum of Natural History in Martinsville, VA. His research focuses on the evolution of reptiles during the Permian and Triassic periods, a time of great change that saw the rise of the dinosaurs. Please check out the Virginia Museum of Natural History at vmnh.net. Dr. Pritchard has also co-produced the paleontology podcast series Past Time, available at www.pasttime.org. Gabriel-Philip Santos, M.S. (/u/vertpaleoama) is a paleontologist and educator at the Raymond M. Alf Museum of Paleontology in Los Angeles, California. His previous work focused on the paleontology of Southern California, particularly the evolution of marine mammals. Today, his research has shifted to education and DEI in STEM as a National Geographic certified educator and cofounder of the Cosplay for Science Initiative. You can find him online as @paleoparadox. Karie Whitman, M.S. (/u/vertpaleoama) is a fossil preparator and research technician at the Duke Lemur Center's Division of Fossil Primates. She carefully uncovers fossils from the rock they are encased in, makes them sturdier, and puts broken pieces back together. She can also make realistic copies of fossils for museum display. Find her on Twitter @whitmankl. We will be back to answer questions starting around noon (Eastern Time/4PM UTC) to answer your questions. See you soon! submitted by /u/VertPaleoAMA [link] [comments]

Do microwaves destroy nutrients in ways that stoves or ovens do not? Posted: 14 Oct 2020 03:35 AM PDT Setting aside any conspiracy theory, I was looking for scientific evidence (with citations if possible) that support or debunk the claim that microwaves destroy nutrients, or are otherwise less healthy, than heating (or reheating) food on a stove or in an oven. (No, this isn't some homework assignment I've been given - look at my post/comment history and you'll see I'm a 39yo dude who's not in college :) Thanks! submitted by /u/agent_uno [link] [comments]

Why is heat emitted as infrared? Posted: 14 Oct 2020 03:25 AM PDT I understand all objects above 0 Kelvin emit thermal energy in the form of infrared but why is it that specific part of the spectrum and not radio waves or visible light for example? submitted by /u/Chicken_Dimmer [link] [comments]

Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 14 Oct 2020 08:08 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience.

How does heat cause the breaking of covalent bonds in thermal cracking? Posted: 14 Oct 2020 07:27 AM PDT submitted by /u/alalala001 [link] [comments]

How did birds develop wings? Posted: 13 Oct 2020 09:47 AM PDT I understand gradual evolution like a species of rabbit becoming faster over time, or small mammals increasing in size to become grazing herbivores like cows because the incremental changes grant advantages. A rabbit that is slightly faster than another will have a higher chance of reproduction, but wings are essentially useless until they reach a point where they allow for flight. It's not like a land animal that has half a wing will have any advantage over one that has none. Did a mutation occur where an animal had functional wings after one generation? My question isn't specific to wings but it was the most obvious example I could think of. submitted by /u/asabasa [link] [comments]

What deadly viruses could we feasibly eradicate in the future - which ones will probably always be around? Posted: 13 Oct 2020 01:33 PM PDT submitted by /u/softserveshittaco [link] [comments]

Do viruses develop unique DNA or RNA based on their host? Posted: 13 Oct 2020 05:46 PM PDT That is, if I get a virus, and you get a virus, and then person 3 and person 4 get that virus from one of us, is it possible to know, via DNA/RNA, which one of us gave the virus to 3 or 4? Put another way, once Bob gets a virus, is it possible to trace that virus back to Bob via DNA or RNA? Or are any mutations just random, so you can identify virus variant 1 and virus variant 2, but you can't trace them back to an individual? (The idea of a "Bob-flavored" virus is gross but kind of what I'm asking.) submitted by /u/thunderbumble [link] [comments]

AskScience AMA Series: We are scientists on the OSIRIS-REx mission, NASA's first mission to collect a pristine sample of an asteroid to return to Earth for future study. The first sample collection attempt is October 20. Ask us anything! Posted: 13 Oct 2020 04:00 AM PDT If you are traveling over 200 million miles to snag a sample of an asteroid, you want to make sure it's worth it. The following scientists are part of the OSIRIS-REx mission - NASA's first mission to collect a sample of an asteroid and return it to Earth. They have just published a collection of papers that confirm that asteroid Bennu - the target of OSIRIS-REx - is an ideal candidate to reveal clues about the origins of life in our solar system. These discoveries complete the OSIRIS-REx mission's pre-sample collection science requirements and offer insight into the sample of Bennu that scientists will study for generations to come. The discoveries tell us that Bennu: Contains carbon-bearing, organic materials Likely used to interact with water Has a type of porous rock that would offer a new, unique perspective to our meteorite collections on Earth Is made up of an interior not uniform in density Contains ridge-like mounds that stretch from pole to pole and has differently shaped hemispheres Has areas, including our sample site, that have not been exposed to a lot of space weathering Read the press release on these discoveries: https://www.nasa.gov/feature/goddard/2002/osiris-rex-unlocks-more-secrets-from-asteroid-bennu Participants: Michael Daly - York University/Canadian Space Agency Daniella DellaGiustina - Image Processing Lead Scientist, University of Arizona Jason Dworkin - Project Scientist for the OSIRIS-REx Mission, NASA Goddard Space Flight Center Hannah Kaplan - Research Space Scientist, NASA Goddard Space Flight Center Jay McMahon - University of Colorado Boulder Benjamin Rozitis - The Open University, UK Amy Simon - Planetary Scientist, NASA Goddard Space Flight Center Ask us about what we've already learned from Bennu and what we can learn from a sample of this asteroid! We'll be answering questions from 2 - 3pm ET (18 - 19 UT), ask us anything!.

In Special Relativity if an object has no mass then it is predisposed to travel at c. Why is that? Or is it an assumption? Posted: 13 Oct 2020 04:52 AM PDT I don't know if no mass requires an object to travel at the speed of light is an assumption built into SR or if it is derived from other basic principles. If it's derived, what from? (Don't be afraid to use some maths.) submitted by /u/the6thReplicant [link] [comments]

Is the coranavirus actually red? The stylized pictures I see of it always show it as red, do viruses have colors if you look at them under a microscope? Posted: 12 Oct 2020 01:43 PM PDT submitted by /u/olblueysmith [link] [comments]

When we say the Earth is 4.6 billion years old, does that mean it has circled the sun 4.6 billion times or that it is 4.6 billion years as measured in 2020 time old? Posted: 12 Oct 2020 06:28 PM PDT Same thing with carbon dating. Is our unit of measurement fixed to the length of a year today? Or as you count back and the earth's revolution around the sun takes more time does the unit change? submitted by /u/Foxcecil [link] [comments]

How did Chinese officials know to look for a novel virus in the early days of the SARS-CoV-2 outbreak? Posted: 12 Oct 2020 06:09 PM PDT What triggered the search to determine the specific virus? Is there some sort of protocol in place that catches these things? Maybe I'm naive, but I'm impressed with how quickly China was able to determine it was a new virus given how common and broad the symptoms are. submitted by /u/re-redditin [link] [comments]

How do we know that mass extinctions happened in the past ? Posted: 12 Oct 2020 05:00 PM PDT How can we know that ? or even know how many extinctions happened ? submitted by /u/Mars-Goliath [link] [comments]

When and how did people realize that there is no land under the Arctic ice cap and that there is land in Antarctica? Posted: 12 Oct 2020 08:34 AM PDT As far as I understand (I could be wrong), the first Antarctic expeditions (Cook, Lazarev/Bellingshausen, Bransfield, Palmer) didn't reach anything not made of ice. The same, obviously, applies to the Arctic expeditions. submitted by /u/avolodin [link] [comments]

Where is the mass of plants coming from? Posted: 12 Oct 2020 06:04 AM PDT I find it very disconcerting that as my plants grow, the soil level in the pots stays the same. Where is the bulk of mass coming from then? Intuitively I can't believe that the carbon captured from the air can account for all that mass. submitted by /u/me-gustan-los-trenes [link] [comments]

Do we know that covid won't be like HIV and kill its victims 10 years from now? Posted: 12 Oct 2020 04:09 AM PDT Is there any evidence for or against the idea that Covid could be like HIV, and silently hide in its victims for many years and then kill them? Are we going to have a whole generation of people dying 10 or more years from now who had covid? The thought is terrifying, as it's a new virus. submitted by /u/FeelThePower999 [link] [comments]

Why does gene damage & mutation eventually end up with cancerous cells but not with something else? Posted: 12 Oct 2020 02:25 AM PDT For example why doesn't it end up with absurd but harmless features? Like, say, you have serious gene damage & mutation in the cells of your breast. Why do those cells become rapidly growing & reproducing cells, instead of, idk, growing weird red hairs on your breast? It might sound dumb and sci-fi but I hope you get the point. submitted by /u/beersty99 [link] [comments]

How did Pauli know the neutrino was nearly massless? Posted: 12 Oct 2020 01:54 AM PDT In the letter that Pauli wrote where he first suggested the existence of the neutrino, he lists the conditions that the particle should be electrically neutral, spin 1/2 and very light (he specifically says similar to the mass of the electron) I understand why he knew it should be electrically neutral and spin 1/2, but how did he know that it should be very light? submitted by /u/The_strangest_quark [link] [comments]

Since sun’s gravity is stronger than earth’s. Why does the moon rotate around earth not the sun? Posted: 11 Oct 2020 10:30 PM PDT I know that it does that because it's closer to earth. However, I feel like I need more details to comprehend. submitted by /u/Jue-Viol-Grace [link] [comments]

How do scientists measure the drainage basin of a river? Posted: 11 Oct 2020 11:48 AM PDT I read a comment on here saying that most of the continental US drains into the Mississippi River. What sources of water are they measuring, and how do they calculate the total land area that's feeding into a given river? submitted by /u/arizona_greentea [link] [comments]

What's the relative speed of ribosome with respect to coronavirus RNA (within host cell)? Posted: 12 Oct 2020 12:42 AM PDT Also, I should be grateful if someone tell me whether the copying phenomenon is done in a unique way, or it may has error/s and results in different production of virus RNA. submitted by /u/UseAirName [link] [comments]

How long to cultivars live? I am asking about ancient fruit varieties. Say I find an old apple tree, get young scion wood and graft it to healthy new rootstock. It's genetics are 100+ year old. Is this new scion approaching senescence? Posted: 11 Oct 2020 07:23 PM PDT submitted by /u/Rexrowland [link] [comments]

Why will cocoa powder only mix with warm/hot water but won't with cold water? Posted: 11 Oct 2020 06:52 PM PDT So I noticed when mixing cocoa powder with water than when I pour cold water into the powder it really resist mixing up properly and it leaves a lot of cocoa powder dross on top even after lots of stirring. But when I pour warm/hot water it mixes up with little to know stirring. I suppose this is a food science question so I will tag it chemistry without that as an option. submitted by /u/pancakelife [link] [comments]

If you receive antibody treatment for covid-19, does your body produce fewer of its own antibodies, leaving you more vulnerable to re-infection afterwards? Posted: 11 Oct 2020 08:05 AM PDT submitted by /u/fatcharliethearkange [link] [comments]

In general relativity, why do objects with different velocities have different trajectories? Posted: 11 Oct 2020 09:01 PM PDT The theory of general relativity says gravity is not a force, but a curvature in spacetime. When you throw a ball, the ball falls down to the ground not because the Earth is pulling the ball down, but the ball is following a straight line in a space distorted by the mass of the Earth. When I picture this in my mind, I think two balls thrown from the same point in space with different velocities should follow the same trajectory, and the only difference should be faster ball hitting the ground faster. Of course this is not true in real life. Can someone please point out what's wrong with my mental model? submitted by /u/kimhyunkang [link] [comments]

Do we understand exactly how smoking cigarettes causes cancer or is it based on very strong demographics evidence? Posted: 12 Oct 2020 12:17 AM PDT submitted by /u/BackIn2019 [link] [comments]

How do we detect covid ? Posted: 11 Oct 2020 08:47 AM PDT Hi, so I don't know, and I'd like to, how do we detect a positive to covid person ? What are we looking for during the test, the virus itself, or a reaction from the body ? submitted by /u/Juliette-Eih [link] [comments]

What are pimples and why do we get them? Posted: 11 Oct 2020 08:09 AM PDT What are pimples, why do we get them, and why do some people get extreme amounts while others seemingly get nothing? submitted by /u/FragmentedPhoenix [link] [comments]

an energy need to make the antiproton? Posted: 11 Oct 2020 07:13 AM PDT I heard the minimum energy to make a antiproton is about 5.6GeV, but I can't find out how this calculated. (or is this wrong?) If that's fact, the proton-antiproton pair annihilation reaction makes about 1.8GeV so we can't get energy with this reaction theoretically? Or if we make many antiprotons, can the average energy required to make one antiproton be less than 1.8GeV? thanks in advance. submitted by /u/NewThinking_07 [link] [comments]

What’s the deal with foxes? Is there an evolutionary link between different genus’s that separates them from other canids? Posted: 10 Oct 2020 08:08 PM PDT I saw a post recently about island foxes in California which led me to their Wikipedia page. On the page I noticed that were classified under the genus Urocyon instead of Vulpes, which is what I'd assumed all foxes were. This led me to the Wikipedia page for the genus Vulpes which are "true foxes" due to the fact they belong to a proper clade which as I understand means they can be traced to a common ancestor. On top of this I see there are a bunch of other fox genus's outside of vulpes. So my question is: What defines a fox? Outside of Vulpes are they just canids that share common physical traits? The thing I'm mainly interested in is: How much of a difference is there between true foxes, other foxes and other canid genus's? Like evolutionarily is an island fox closer to a red fox than a jackel or something? Or is it just convergent evolution and they're being named for their physical traits? submitted by /u/stoppokingmeshit [link] [comments]

Does air separate in an enclosed container when you swing it around? Posted: 09 Oct 2020 04:15 PM PDT My question is about separating carbon from the air. If carbon dioxide is 1.5 heavier than the rest of the air around us, why can't we enclose it in a bucket and swing it around until it separates, then pump it out of the separated segment of the bucket with the CO2 in it? submitted by /u/insultinghero [link] [comments]

Posted: 10 Oct 2020 02:21 AM PDT This isn't COVID-19 specific, but the COVID vaccine being developed in my country has been paused a number of times due to one trial member becoming unwell. Aside from being infected from a live-attenuated vaccine, what other issues do you encounter? What about non-live vaccines? submitted by /u/TommyMac [link] [comments]

How did we find out electrical currents are made of negative charges, rather than positive? Posted: 09 Oct 2020 11:23 AM PDT As I understand it (I may have it wrong) the reason conventional current flows in the "wrong" direction is that Benjamin Franklin (and I assume other people of his time) thought electrical currents were made out of positive charges. How and when did we realize this was not the case? submitted by /u/quietandproud [link] [comments]

What's the deal with Centrifugal force? Posted: 09 Oct 2020 10:56 PM PDT Some say it's a fictional force, and that only centripetal force exists. But then, why do vehicles move away from the center of the round-about when going around one, rather than towards it? Could someone please help me with this? submitted by /u/2020-MostChaoticYear [link] [comments]

What is actually the double slit experiment? Posted: 10 Oct 2020 02:36 AM PDT As far as I understand , when photons are emitted one by one via two slits they begin to show an interference pattern behind the slit , but if we observe it before it passes through the slit, there will only be two bright fringes on the screen But I can't find any video or pictures regarding the second case where only two fringes are formed Did I understood wrong ?

When an electric vehicle drives does each battery cell use its power one by one? Or do they all slowly lose power at the same time? Posted: 09 Oct 2020 06:33 PM PDT submitted by /u/onlyweartherobe [link] [comments]

Can cancer be contagious? Posted: 09 Oct 2020 08:17 PM PDT I'm not referring to things like oncogenic viruses or infectious agents that can cause cancer; rather, if cancerous material from one individual (say a fleck of a tumor) enters another individual (say it got into their bloodstream through a cut), could it thrive in the host environment? I'm guessing the immune response would make this difficult, but given that cancers replicate so quickly and aggressively, could this happen? submitted by /u/ImperialAuditor [link] [comments]

Which place on Earth is more shielded from charged particles coming with solar wind? Posted: 08 Oct 2020 11:22 PM PDT As far as I understood, the Earth's Van Allen belts are the thickest an the equator, while in the polar regions something called polar cusps exist, which are the special regions in Earth's magnetosphere where the charged particles are not trapped but funneled down into the atmosphere which causes the events like the auroras. Does this mean that polar regions of the Earth and their inhabitants are more exposed to the harmful charged particles brought by the solar wind? Further, if that's the case, how does this exposure compare with the exposure closer to the equator? As I understand, there will be less exposure to the charged particles but more exposure to the UV and other types of radiation because of the longer daytime duration. Do the auroras represent the particles that have already lost their energy by ionizing the atmosphere and are no longer dangerous? submitted by /u/sillyinky [link] [comments]

In the “carbon budgets” we often see in climate policy reports, are they also budgeted for other gases e.g methane, NOx, HCFCs etc? Posted: 08 Oct 2020 12:51 PM PDT submitted by /u/ballan12345 [link] [comments]
