| Do NSAIDs help soft tissue injuries heal? Posted: 03 Mar 2022 06:21 AM PST A medical student that I know was the opinion that NSAIDs should be taken in the case of soft tissue injuries and that these help them to heal faster. If I look this up, most of the advice available on the internetz is actually to the contrary - inflammation is necessary for injuries to heal, and anti-inflammatories can slow down the healing process. Which of these answers is true? The information seems pretty contradictory and the studies admit to a need for more investigation, there doesn't seem to be any consensus. [link] [comments] |
| Why does the Hawaiian underwater mountain chain make a huge turn? Posted: 03 Mar 2022 08:54 AM PST Looking at the Hawaiian hotspot, the underwater mountain chain makes a large turn a bit before it disappears. Why did it make such a turn? Was it the hotspot or the plate? Do such big shifts in direction happen often? [link] [comments] |
| Posted: 02 Mar 2022 10:54 PM PST As I understand it, synapses are neurons making contact with one another. So to make new synapses, the neurons would have to change on a cellular level. Surely this would take hours, or possibly days (or more) to happen. So why is it, if (for example) someone tells me their name, I'm sometimes able to remember it immediately for a very long time despite only being exposed to that information for far too short of a time for my brain to physically change?

| Posted: 03 Mar 2022 02:39 PM PST Is it possible for birds to cross breed, like dogs/cats do? From my observations, I don't recall seeing any hybrid birds that may have been the result of cross breeding, like an owl with parrot colours. Is this because of the evolutionary drive of these animals being so ingrained that they have no desire to cross breed? Or are they unable to cross breed (does this make them different species)? Or is there another explanation? [link] [comments] |

| How can you determine the most efficient gear ratio for an electric motor? Posted: 03 Mar 2022 07:33 PM PST I am part of a robotics team and thought that it would be useful to find the relationship between gear ratio and the efficiency of a DC motor. When I looked it up I found plenty of graphs that represent the efficiency as a parabola, increasing as RPM increases and torque decreases, then dropping after a 'peak' efficiency is reached. However, I couldn't find any explanations of why it takes this shape, or what determines the location of this peak. My understanding was that speed is, well, speed, while torque is the ability of a motor to start moving in the first place. So I thought that the efficiency would continuously increase with speed, until the torque is too low to move the load and the motor stalls, dropping efficiency straight to 0 rather than a gradual decrease. Is there something that I am missing? [link] [comments] |
| Are charcoals in soils always a good thing? I.e. Biochars and post processing Posted: 03 Mar 2022 08:40 PM PST https://www.youtube.com/watch?v=YB9g9l5CjGk Charcoals have polar surfaces with tremendous numbers of nooks and crannies and are found ubiquitously in the world's soils deposited from fire. These legacy structures modulate soil fertility, individual plant response, and subsequent large-scale ecosystem patterns. In recent years, incredible attention has been paid to their use as a soil amendment - converting waste biomass into charcoals, "biochars" - dually capturing carbon and increasing soil fertility in managed ecosystems. Most data synthesis, including my own with Dr. Sean Thomas at Toronto, show on average ~41% increase in biomass responses. Source: https://www.researchgate.net/publicat... However, much variation ensues from the applied usage in agricultural and forestry contexts - including negative responses. The mechanisms that drive these detrimental effects are many. Still, research shows that low molecular weight leachates (i.e., acids, phenols, VOCs), Ash, and sometimes metals could be responsible for a mismatch in soil physiochemistry. Source: https://peerj.com/articles/2385/ This video discusses ways to enhance biochars efficacy and is delivered by my Ph.D. advisor - Sean Thomas, at the United States Biochar Initiative, 2020. An expansion of our work and what is written above follows in the talk. And his recent paper: https://link.springer.com/article/10..... What do you all think? Any other biochar folks here to help weight in? [link] [comments] |
| Posted: 03 Mar 2022 12:35 PM PST As the title says, does the wood drilling have any health repercussions on a woodpecker? And also, is the skull built in such a way to prevent damages to the brain? Thanks! [link] [comments] |

| Posted: 03 Mar 2022 05:30 PM PST As a once-geneticist, I feel like I should know this answer, but I can't find anything on it. My only thought is to maintain some semblance of order as the furrow forms, ensuring that the meiosis 1 daughter cells obtain the correct chromosomes, but I would not be surprised if there was more to it. Teaching to inquisitive freshmen and juniors who I just know are going to ask me this, and I'd like to have a decent answer for them! [link] [comments] |
| Posted: 01 Mar 2022 10:44 PM PST It's kind of something I've wondered for a long time, I've always had this small fear of the idea of just falling upwards into the sky, and the moons low gravity sure does make it seem like something that would be possible, but is it actually? EDIT: Thank you for all the answers, to sum up, no it's far outside of reality for anyone to leave the moon without intent to do so, so there's no real fear of some reckless astronaut flying off into the moon-sky because he jumped too high or went to fast in his moon buggy.

| Posted: 02 Mar 2022 04:00 AM PST Hi! I'm Dr. Alex Schnell, a Research Fellow from Darwin College at the University of Cambridge. I'm a comparative psychologist interested in the behaviour and mental processes of animals. More specifically, I investigate learning, memory, and self-control in mainly cephalopods (e.g. octopuses and cuttlefish). My findings have contributed to our understanding of the evolution of complex cognition and how certain cognitive abilities may have arisen independently in invertebrate taxa. 2021 was a productive year. Two of my papers showing that cuttlefish have both self-control and what's termed "episodic-like" memory were the Royal Society's fifth- and sixth-most-talked-about papers, respectively. Watch VIDEO of cuttlefish pass the "marshmallow test" here! I was also part of a team at the London School of Economics and Political Science that reviewed the evidence of sentience (the capacity to experience emotions) in both cephalopods and decapods (e.g. crabs, shrimp, lobsters). Our central recommendation, which is now being implemented, was to include both these groups of invertebrates in the UK Sentience Bill. This means, for the first time, these groups will be protected under animal welfare law. My career purpose has been to further our understanding of the remarkable behaviours of animals in the hope that I might inspire more people to appreciate the incredible wonder of animal life on Earth. When people understand nature, they are more motivated to preserve it, research shows. I joined the University of Cambridge as a Visiting Researcher in 2016 and became a Research Fellow in 2018. Prior to Cambridge, in 2007, I obtained a B.A. in Marine Science at the University of Sydney. In 2015, I completed my Ph.D. on the behavioural ecology of giant cuttlefish at Macquarie University. I then held several post-doctoral positions with my experimental research based at a leading cephalopod research facility, the Marine Biological Laboratory in Massachusetts. My postdoctoral research focused on different aspects of cuttlefish cognition including perception, learning, and memory. I also won a prestigious Grass Fellowship in Neuroscience, a program that supports early career researchers to bridge the gap between neuroscience and behaviour. I've also worked as a BBC series researcher for Planet Earth III and Life of Mammals II, and my work was featured in a NOVA PBS digital documentary on YouTube. Most recently, I worked for Wild Space Productions and Freeborne Media to produce a major new series for Netflix entitled 'Oceans.' My aim in these roles was to highlight new findings on animal behaviour to give the public a new dimension for understanding wildlife. I'll be on in the afternoon (ET), AMA!

| Why are anti-Saccharomyces cerevisiae antibodies used for identifying certain IBD diseases?

Any current theories why there appears to be a relationship? [link] [comments] |
| Posted: 03 Mar 2022 03:37 AM PST It seems like it would be stressful and not advantageous for whale vocalizations to waste air. Do whales have to strategically decide whether or not to sing based on their air quantity or do they make sound some other way that does not use air? [link] [comments] |
| Posted: 03 Mar 2022 10:01 AM PST I'm aware of the concern about antibiotics and drug resistance leading to a concern about superbugs. Does it work the same way for coronaviruses? If we use antiviral pills, could that lead to coronavirus becoming drug-resistant and more difficult to treat? [link] [comments] |
| Why are earth’s natural resources seemingly not evenly distributed across the planet? Posted: 02 Mar 2022 06:57 PM PST I've been thinking about how certain countries are hotspots for either oil, cobalt, gold, diamonds, platinum, whatever resources. What happened during the earth's formation and the past several hundred millions of years of revolving around the sun, to where certain resources seem to be mostly concentrated in specific countries around the world? Other than natural caves, why can't we simply excavate to the same depths and find the same metals in any country? [link] [comments] |
| Why is atomoxetine not considered a stimulant? Posted: 03 Mar 2022 10:08 AM PST Please let me know if there is a better subreddit for this question. I am doing some research on medications for ADHD and found that there are stimulant and non-stimulant medications. Atomoxetine (brand name Strattera) is considered a non-stimulant medication, but when I looked into it's mechanism of action, I found that it inhibits reuptake of norepinephrine and may indirectly increase dopamine activity as well. It was my understanding that any drug that increases dopamine and norepinephrine activity is considered a stimulant, so how is atomoxetine not considered a stimulant? Can someone give me a more precise definition of stimulant that excludes atomoxetine? [link] [comments] |

| What is the most abundant cell type in the body? Posted: 03 Mar 2022 02:38 AM PST I stumbled upon a statement in a hematology textbook (Rodak's Hematology) found in page 3 of its both 5th and 6th editions. It says that macrophages are the most abundant cell type in the body, much more than RBCs or skin cells. I got really confused and got no answers from internet that supports that it is really macrophages. So, is it really macrophages, RBCs, or skin cells? [link] [comments] |
| How long into humanity did it take before numbers were conceptualised? Posted: 02 Mar 2022 08:04 PM PST Been thinking about the evolution of communication between humans a lot lately and I was curious to see if anyone knows or has theories around how numbers came into the picture.

| Are geostationary satellites only around the equator? Posted: 01 Mar 2022 01:06 PM PST I assume the orbital planes of every satellite has to cross the centre of the earth, otherwise what are they turning around? And geostationary satellites are meant to stay still in the sky when you look up at them, right? But that only works around the equator otherwise the geostationary satellite would move up and down along a north-south straight line in the sky when you look at it from a point on the ground.
