How are blood vessels connected in a partial liver transplant? Posted: 14 Feb 2021 08:25 PM PST The liver has several crucial blood vessel connections. How are transplants 'hooked up' to them? They can't be just sewn on can they? Isn't there a rather large size difference between the primary vessels and the vessels present in the donated organ? submitted by /u/jwizardc [link] [comments]

AskScience AMA Series: We are evolutionary biologists from the University of Tennessee celebrating Darwin Day. Ask Us Anything! Posted: 15 Feb 2021 06:14 AM PST Hello! We are evolutionary biologists from the University of Tennessee with a wide variety of research backgrounds. We are here celebrating a belated Darwin Day, which commemorates the birthday of Charles Darwin each year on February 12. Joining us today are: Krista De Cooke, PhD student (u/kdec940) studies the spread of invasive plants and native plant alternatives. Her work aims to develop practical tools to help people select appropriate plants for their needs that also serve a positive ecological purpose. Stephanie Drumheller, PhD (/u/uglyfossils) studies paleontology, especially taphonomy. Her 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. Amy Luo, PhD student studies the evolution of bird song dialects. Brian O'Meara, PhD (/u/omearabrian) is an evolutionary biologist at the University of Tennessee and President-Elect of the Society of Systematic Biologists. His research focuses on methods to study how traits have changed over time and their potential impact on other traits as well as speciation and extinction. Find him on Twitter @omearabrian and the web at http://brianomeara.info. Dan Simberloff, PhD (u/kdec940) is a leader in the field of invasion biology and the Nancy Gore Hunger Professor of Environmental Studies at the University of Tennessee. He studies the patterns displayed by species introduced outside their geographic ranges, the impacts such species have on the communities they invade, and the means by which such invasions can be managed. Ask us anything! We will be answering questions starting around 5pm Eastern Time, 10 UTC. submitted by /u/AskScienceModerator [link] [comments]

How significant is fever in suppressing virus outbreaks? Posted: 15 Feb 2021 07:21 AM PST I was recently sick in Covid 19, during the sickness i developed a slight fever. I was recommended to not use Ibuprofen to reduce the fever since that might reduce the body own ability to fight the virus and therefor prolong the sickness How much, if any, effect does fever have on how long you are sick? submitted by /u/Theremere [link] [comments]

Is coughing an evolutionary advantage? If so, why do we try to suppress it with cough syrup ? Posted: 14 Feb 2021 05:19 PM PST Coughing is the way our body tries to get rid of foreign bodies out of our lungs. I wonder why we should prevent our body to cough, even if it allows us to get rid of some virus. I understand that it slows down the spreading of the disease, however I don't understand, from an evolutionary point of view, why this feature was kept. If it is so disadvantageous, why would this trait survive ? If it's advantageous, why do we suppress it ? submitted by /u/Ulzaf [link] [comments]

Why is it that the AstraZeneca vaccine has a reduced efficacy on the B1351 Corona strand? Posted: 15 Feb 2021 04:54 AM PST As far as I know both types of vaccines, mRNA and vector, accomplish the exact same response from the human body, producing the spike protein present on the SARS-cov-2 virus. Therefore I find it strange, that the mRNA vaccines show higher efficacy than the Vector vaccine by AstraZeneca. submitted by /u/MOOOthePRO [link] [comments]

Is lithium that common in the earth's crust? and nickel? Posted: 15 Feb 2021 04:58 AM PST Hi I heard Elton Musk say in a podcast that lithium is one of the most common elements on earth, and that we could find it anywhere. Nickel was a little more difficult. After a brief survey he obtained the information that lithium is number 32 and nickel 23, in terms of abundance in the earth's crust. Can anyone clarify me about this? Could Elon Musk be wrong? Thanks submitted by /u/taparuere [link] [comments]

Is peripheral vascular resistance different from systemic vascular resistance? Posted: 15 Feb 2021 06:56 AM PST In StatPearls at NCBI website, they have 2 different but connected chapters explaining each. Is there a difference between the usage of these terms? submitted by /u/10thingsIhateAbout [link] [comments]

Post translational removing of methionine? Posted: 15 Feb 2021 06:53 AM PST The methionine codon AUG is also the most common start codon. A "Start" codon is message for a ribosome that signals the initiation of protein translation from mRNA when the AUG codon is in a Kozak consensus sequence. As a consequence, methionine is often incorporated into the N-terminal position of proteins in eukaryotes and archaea during translation, although it can be removed by post-translational modification. I wonder is there statistics about how many percent of the proteins have their N-terminal methionine removed in all organisms and for example in human? I can infer it's like almost all? submitted by /u/mehelek [link] [comments]

Presence of SRP in LUCA? Posted: 15 Feb 2021 06:51 AM PST Signal recognition particle (SRP) is ribonucleoprotein. Does presence of RNA and fact, that no organism evolved protein-only SRP, say that LUCA could have this ribonucleoprotein? submitted by /u/mehelek [link] [comments]

In theory, could heavier metals that are either magnetic or paramagnetic (e.g. chromium, copper, iron, manganese, etc.), accumulated in the bone or tissue of a person, be affected by an MRI scan, either causing heating or movement of tissue? Posted: 15 Feb 2021 04:38 AM PST There seem to have been some reports of metals in tatoos possibly being affected, but what about those metals in tissues or bone, accumulated either through a lifetime of diet or by toxic exposure. submitted by /u/etherified [link] [comments]

How did early human discovered the uses of fire, and How do they make a fire at the first place? People said that early human made a fire from striking flint with a minerals called "Pyrite", but how did they know that striking those things would make a fire?

How are public/private cryptographic key pairs actually generated? Posted: 14 Feb 2021 12:45 PM PST Everything I read seems to always be really heavy on simple example theory and totally empty on real world implementation. Like how does my computer know what massive primes to use? How does it even know they are prime? If there is a list of primes to use then aren't there tables that would easily break public keys? submitted by /u/ItsDijital [link] [comments]

Why are the target northern and southern latitudes for a Mars sample return mission not equal? Posted: 14 Feb 2021 10:30 AM PST Proposed landing sites for MSR missions appear to target a latitude range of -5 degrees to 25 degrees. Why wouldn't these two values be equal and opposite? Sources for clarification- https://www.lpi.usra.edu/planetary_news/2014/04/04/scientists-favor-four-exomars-landing-sites/ https://mepag.jpl.nasa.gov/meeting/2011-06/P3_GRANT_Landing_Sitesv3.pdf Page 9: -14.9 degrees stresses southern latitude limit submitted by /u/a_bar_named_puzzles [link] [comments]

Moderna vs Pfizer/Biontech BNT162b1 vs BNT162b2? Posted: 14 Feb 2021 02:39 PM PST There are people that says that the Moderna vaccine should work as well as Pfizer/Biontech because they uses the same spike. Do anyone know how much difference there are between Moderna and BNT162b2 compared to between BNT162b1 and BNT162b2? What was the problem with BNT162b1 that made it fail before phase 3? submitted by /u/johnnydues [link] [comments]

mRNA vaccines work by introducing an mRNA sequence which is coded for a disease specific antigen. Is it possible to introduce an mRNA sequence that directly codes for the antibody? Posted: 14 Feb 2021 10:54 AM PST submitted by /u/Bearr09 [link] [comments]

How did theropods support their weight on two legs? Posted: 14 Feb 2021 03:50 AM PST There are a lot of incredibly large theropods like T-Rex, giganotosaurus, spinosaurus, etc. which seem to exceed large animals like elephants in weight, even though elephants are quadrupedal. I'd like to know how the leg bones of theropods were able to support the weight of these animals on two legs. I have read that hollow bones, as seen in birds and theropods, are supposed to be very strong, but I've also read that large animals like elephants and sauropods have almost entirely solid leg bones to support their weight. submitted by /u/HorrendousHexapod [link] [comments]

Why is Flash photography not allowed in museums? Posted: 14 Feb 2021 04:49 AM PST Tagging physics but it might be chemistry. What's the story about the flash that damaged the old things?

What exactly causes a virus to mutate? Does it have anything to do with the carrier? Posted: 14 Feb 2021 05:57 AM PST Have they ever done tests on people with new strains to test their genetic makeup to see if there's some commonality like a specific genetic mutation? submitted by /u/heyimjason [link] [comments]

Why do animals have different lifespans? Posted: 13 Feb 2021 06:26 PM PST This seems like a really stupid question but here goes: My dog is 7 and she's obviously gonna die much younger than I will. That got me to wondering, since she's a mammal like me, with roughly the same batch of parts, why do we have such different lifespans? Also, why do some dog breeds live way longer than others? It seems to have something to do with size, but there doesn't seem to be an exact correlation. What is it in our genes that says "this many years for a human, this many years for a dog, this many for a horse, etc.?" Thanks in advance for the education! submitted by /u/kahnwiley [link] [comments]

How is it determined if an earthquake is a main quake vs after/before shock? Posted: 14 Feb 2021 01:44 AM PST Just last night Northern Japan suffered a 7.3 magnitude earthquake. News outlets reported today that the quake was an aftershock from the 2011 9.0 magnitude Tohoku quake. ​ What does this mean? I had assumed that aftershocks/before shocks were simply temporally associated, but there have been many earthquakes since 2011 in that region that were not considered aftershocks. What makes this one different than the other quakes that have come before it? How is it determined if an earthquake is a main quake vs after/before shock? submitted by /u/arthouse2k2k [link] [comments]

Could mRNA technology be used to improve the seasonal flu vaccine? Posted: 14 Feb 2021 04:55 AM PST I've read several articles that claim mRNA vaccines make changing the payload very easy. It's a supposedly simple matter of producing the same vehicle but with a different mRNA strand inside. I've read claims that if we needed an updated vaccine to handle the new COVID strains, it could be made in a few weeks. Would this tech be adaptable to the seasonal flu vaccine? Would it give advantage over the current production methods? Could this let us make vaccines that better match circulating strains, because we wouldn't have to start production so far in advance of flu season? Could this remove the dependency on huge numbers of chicken eggs for flu vaccine production? submitted by /u/auraseer [link] [comments]

How do the mother koala keep her pouch clean while the baby koala is living in it? Posted: 13 Feb 2021 03:11 PM PST submitted by /u/QuarantineNudist [link] [comments]

Why does wavelength determine the kind of EM a mesh blocks? Posted: 13 Feb 2021 02:29 PM PST Due to both an RF circuit design class and personal interest, I've been reading up on radios and antenna design and came across a fact that I think illustrates some error in my visualization of how EM waves propagate. In a microwave appliance, there is a metal mesh behind the front window that blocks microwaves from escaping. The explanation for this is that the holes in this mesh are small enough in relation to the wavelength of the microwave such that there is not enough space for them to pass through. In TEM mode like this would be in free air both amplitude components of the wave are perpendicular to the direction of propagation, however, they are measures of field strength so should be unrelated to matters of distance like hole size. But wavelength is a measure of distance along the axis of propagation, so how does changing the size of a hole in a mesh prevent a discrete ray from travelling through it normal to the plane of the hole? If the light is like a train and the mesh is a tunnel I would think that the length of the wave/train is irrelevant to whether that wave/train could get through a tunnel? submitted by /u/Dothwile [link] [comments]

Which constellations will be the first ones to lose their shape with the passage of time? Posted: 13 Feb 2021 12:14 PM PST submitted by /u/rinkoplzcomehome [link] [comments]

[Light] Why is the angle of incidence the same as the angle of reflection? Why is it not twice, or half? Posted: 13 Feb 2021 01:51 PM PST I know this is quite abstract, and maybe it's impossible to know, but is there some reason it had to be that way? submitted by /u/Ouisopsa12 [link] [comments]

What is the general concensus regarding the Sputnik V vaccine? Posted: 14 Feb 2021 12:23 AM PST Hello, I would like to know what's the general consensus of the scientific community concerning the Russian Sputnik V vaccine. I read that it uses the Ad26 and Ad5 adenoviruses and that "these wild viruses are very common in humans and there's widespread immunity to them, so there's the potential that immunity will block the vaccine carrier". I'd like to know if new studies showed that it actually won't affect the 92% reported efficacy or if other issues or promising results were pointed out. submitted by /u/Khelebragon [link] [comments]

Why does Japan get so many earthquakes? Posted: 13 Feb 2021 06:51 AM PST Is it due to fault line proximity or volcanic activity being an island nation. I don't know how it works. submitted by /u/whatthewhat2020 [link] [comments]

Why do Scientists Bombard Specific Elements to Create New Ones? Posted: 12 Feb 2021 08:23 PM PST For Oganesson, it was Calcium and Californium: 20 + 98 = 118. But why not just Praseodymium and Praseodymium? If you bombard element 59 with element 59, shouldn't it also give you element 118? submitted by /u/PopplioUser3674 [link] [comments]

how are planetary rings stable ? Posted: 12 Feb 2021 03:02 PM PST Something just occurred to me, if all extraplanetary masses formed from from gravitational forces acting on small bits of debris pulling them together, and planetary rings are just that except in a stable orbit around a larger mass, how hasn't the same process happened there ? submitted by /u/somethings_off8817 [link] [comments]

Why don't we get blood clots from lying still while we sleep for 8+ hours? Posted: 12 Feb 2021 12:02 PM PST I watched a video about venous stasis and deep vein thrombosis. I followed the logic and thought that if we lie still for a long period of time while we sleep, what's keeping us from developing blood clots? submitted by /u/Lord_of_the_Box_Fort [link] [comments]

Is there a theoretical limit to the energy density of lithium ion batteries? Posted: 13 Feb 2021 08:32 AM PST Title basically says it.

Is it possible to keep creating new elements by just smashing more protons together with enough energy? Posted: 12 Feb 2021 10:00 AM PST As we "discover" more and more elements with half-lives of picoseconds, will they still be considered actual elements? Can you keep adding energy to hold hold a nucleus together long enough to measure to create a new element? EDIT: yeah, I know there's neutrons in the nucleus. That doesn't really change the question submitted by /u/SouthPawXIX [link] [comments]

Why are vaccines in small bottles? Posted: 12 Feb 2021 05:50 PM PST I always thought that its just the way it is, but during this time I wonder why vaccines are always in such small bottles? Wouldn't big gallon jugs be more efficient? submitted by /u/mwcotton [link] [comments]

Has there ever been a theory of gravity as an absence of a repulsive force? Posted: 12 Feb 2021 01:13 PM PST Say, something along the lines of, "mass serves as a shield from xxx particles." You fall to the ground not because gravity attracts you, but because you are "pushed down" more than you are "pushed up". submitted by /u/Lodestone123 [link] [comments]

Can a tree uprooted in an avalanche or landslide reestablish itself further downhill? Posted: 12 Feb 2021 01:11 PM PST I was watching a video and several small pine trees were swept away in an avalanche.

Do any other animals give birth to another offspring while still caring for a current offspring, like humans do? Posted: 12 Feb 2021 07:42 AM PST I saw a photo of a family with a new born when they had 3 other young children and it got me thinking.

Is baking something any different from drying or removing water from it? Posted: 12 Feb 2021 06:22 AM PST I've recently encountered a few individuals who claim that baking is essentially nothing more than controlled drying. It is my understanding that drying is involved but I was under the impression that there were a wide variety of chemical reactions that occurred that wouldn't exactly be "drying" per se. I've looked at a few of the other related reactions like carmelization and Maillard reactions but I'm not able to say for sure if those aren't also complicated removals of water or caused the removal of water. submitted by /u/knightfallx66 [link] [comments]

Why do lupus and fibromyalgia mainly affect women? Posted: 12 Feb 2021 02:01 AM PST I was reading up on both this morning (mother has fibro) and found out that in both about 90% of patients with either condition are women mainly in the childbearing age range.

What is the most common microorganism you would find in the average water sample? Posted: 12 Feb 2021 02:00 AM PST Google seems to not be able to understand that sentence, so I'm just hoping someone in the world can give me an answer for this. Every search result says "bacteria" like that isn't literally billions of different species. I mean what is the most common species that you would find inside the average microscope sample? If I pull water out of a random lake near me, what species am I most likely to see? submitted by /u/AustinQ [link] [comments]

AskScience AMA Series: We're Women in STEM. We use ecological data to fight climate change. Ask us anything! Posted: 12 Feb 2021 04:00 AM PST We are scientists working in the Crowther Lab at ETH Zurich: Lalasia Bialic-Murphy, Senior Scientist - /u/LalasiaM I am Lalasia Bialic-Murphy, a Senior Scientist in the Crowther Lab at ETH Zurich and an Adjunct Research Assistant Professor at the University of Tennessee Knoxville. I study the importance of species interactions and abiotic resources (e.g., soil nutrient and water) in shaping the local abundance and geographical distribution of plant populations. I am particularly interested in understanding the mechanisms that drive species rarity and extinction in a changing world. I was also a field biologist for over 12 years, doing rare species management and critical habitat monitoring in Hawai'i. Understanding how on-going environmental change is affecting native ecosystems is critical for developing informed conservation efforts, and this is my passion. Ask me anything. I would also love to hear your experiences and perspectives on these topics. Let's talk! Iris Hordijk, Doctoral Candidate - /u/IrisHordijk I am a third year doctoral student in the Crowther lab, ETH Zürich. My research focusses mainly on global tree species diversity and the relationship with forest functioning. I am interested in the patterns of tree species abundance, what drives species dominance and rarity, and how do dominant species influence forest productivity. Besides, I am passionate about tropical forest ecology and I am involved in a pan-tropical project on forest regeneration with fieldwork in Mexico. Ask me anything you would like to know related to academic life or my research! Niamh Robmann, Data Scientist - /u/nima-rob After my bachelor's degree in Biology where I was mainly interested in anthropology and ecology, I decided to study bioinformatics & computational biology for my master's degree. I ended up doing my master's thesis in the Crowther lab where I was able to combine my interest in ecology and the newly learned tools and knowledge from my master's study program. Now I am working as a Data Scientist in the lab trying to support the group by adding my more data focused perspective. Kenza Amara, Doctoral Candidate - /u/k-amara I am majored in Computer Science and applied mathematics, and chose to apply my technical skills to environmental issues. So, I decided to pursue a Master 2 in Environmental sciences, because I feel very concerned by climate change. I did my Master Thesis at Crowther Lab, which enabled me to work closely with the department of Computer Science at ETH. I will start my PhD in Computer Science in September but I hope to keep close contact with Crowther Lab and its amazing members! Nina Van Tiel, Data Scientist - /u/mountain_goat_11 With a background in bioinformatics and a strong infatuation for coding, I wanted to use my skills to contribute to fighting climate change. Although there is not much fighting in my daily routine, I support projects that strive to understand global ecology and inform responsible ecosystem restoration, for example, by writing efficient code and running machine learning models. I am a feminist with a particular interest in intersectional, eco-, and trans-feminism. We'll be answering your questions at 14:00-20:00 CET/8:00-14:00 EST (13-19 UT), ask us anything! submitted by /u/AskScienceModerator [link] [comments]

Will the first influenza season after all corona restrictions are lifted be worse than before? Posted: 11 Feb 2021 02:45 PM PST It is my understanding that our immune system needs, to some extend, "training" or rather some exposure to germs in everyday life to keep us healthy. To my knowledge, this is also why overuse of desinfectants (e.g. every time you touch something in public spaces) is actually a bad thing. So, I was wondering whether the next influenza season or some other disease could become worse (meaning more people suffer from it or show more severe symptoms) than before because our immune systems won't be up for the task when the corona restrictions are lifted. submitted by /u/Krustenkaesee [link] [comments]

Since the Milky Way and Andromeda will eventually merge and grow in size, is it possible for 2 galaxies to snowball until there are no other galaxies? Posted: 11 Feb 2021 03:30 PM PST What I mean by snowball is say once the Milky Way and Andromeda collide, since they've grown in mass, they start attracting another galaxy onto a collision course. And then after this that repeats, until it forms one large "super-galaxy" of sorts. This of course most likely wouldn't happen with our 2 galaxies, but out there in the huge universe, there are most likely 2 galaxies that will collide with each other and have good enough conditions to repeat that collision at least a few times, and grow to be a massive galaxy. But, just as a hypothetical, throwing out the expansion of the universe, and the amount of time it would take for all the galaxies to collide and merge, is this possible? submitted by /u/Destructuctor [link] [comments]

Is there a relationship between the concept of high entropy and guage symmetry? Posted: 11 Feb 2021 02:22 PM PST I'm finishing up "Qbism" by Hans Christian von Baeyer and "The Fabric of the Cosmos" by Brian Greene. I was struck by the similarity of the explanations about the microstates involved in quantifying entropy and the concept of gauge invariance. I can't find much online about the relationship, if there is one. I have a feeling that I may be misunderstanding guage symmetry/invariance so I'll give my best understanding of both. Please correct me on anything that's off! One concept of entropy would be the number of "microstates" (molecular/atomic structures) that could create a given "macrostate" (observable system). A glass of water has high entropy because the H2O molecules could be organized any-which way and you'd still have the same glass of water. My understanding of guage symmetry (same as invariance?) its that a field or variable is said to have this property if fiddling with it doesn't change the measurable result. This makes it seem to me like "high entropy" is a synonym for "guage symmetry", or that there may be some tight connection between the two ideas. Can someone sort me out please? submitted by /u/Pvh1103 [link] [comments]

Why cant elements with atomic numbers above 94 be found in nature? Posted: 11 Feb 2021 09:14 AM PST I thought it had to do with the half life of those elements but Curium 248 has a relatively long half life. Longer than Neptunium isotopes which can be found in trace amounts so why? submitted by /u/Anubis253 [link] [comments]

Due to gravitational time dilation, do I weigh more when standing up vs laying down? Posted: 11 Feb 2021 02:48 PM PST submitted by /u/antinym [link] [comments]

Are you able to use computers to be able to tell if somebody has a positive or negative opinion using only sounds? Posted: 11 Feb 2021 07:03 PM PST So, I have been thinking to myself that there's a lot of emotions that people have and some experiments have even used that, like the plant experiment where they make people say either nice things or mean things to each specific plant, so that makes me think, is there a way for a computer to be able to tell? submitted by /u/Ok_Owl6966 [link] [comments]

Would organisms that live closer to extreme heat have weaker immune systems? Posted: 11 Feb 2021 10:28 AM PST Crustaceans like Lava snails, or the animals that live around heat vents near the bottom of the ocean are what I'm curious about. submitted by /u/su-5 [link] [comments]
