| Posted: 16 May 2020 06:43 AM PDT Is this just poor adaptation? In many sports - e.g. weightlifting, climbing - and work activities people need to chalk up their hands or wear tape or gloves for grip, purely to counter this crappy response from their body. I would imagine in a fight or flight situation, evolving humans needed grip much more than they needed a marginal amount of heat dissipation from their hands. [link] [comments]  |
| Posted: 17 May 2020 07:10 AM PDT I know this is a stupid question and I know cancers and viruses are different. I just want to know what prevents us from training them to sniff out viruses since that could be an alternative for testing. Im just curious. [link] [comments]  |
| Why are scientists unsure about whether COVID-19 Antibodies cause long-term immunity? Posted: 17 May 2020 07:27 AM PDT Short question: I keep hearing the same point repeated over and over again. "Scientists don't know if antibodies protect you from reinfection." What exactly do scientists not know? Are they unsure of the B-Cell memory timeline? Do they doubt the antibodies ability to neutralize the virus? Or are they saying this out of an abundance of caution? Longer question: I was a Molecular Biology Major in undergrad. I know some of the big concepts of immunology, but I don't know enough to talk with any authority. Based on what I know, I am going to lay out my theory about why scientists avoid answering this question. Can you please tell me where my theory is incorrect? Essentially, my understanding is that IgM antibodies will give people long-term immunity. COVID does not mutate quickly because it has a RNA proofreading system (Source posted below). Therefore, We shouldn't worry about next year's COVID having different serotypes that our body won't recognize. The other questions is about B-Cell memory. How long will your body continue to produce antibodies? I know that B-cells for Lyme disease have a particularly short memory (less than 6 months). However, everything I've read online indicates that similar Corona viruses leave relatively long B-Cell memories. This article (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2851497/) says that people infected with SARS had around 3 years of elevated IgG. But of course, after 3 years they should still have IgM antibodies, right? If reinfected, shouldn't they be able to replenish their IgG antibodies much faster than the original infection? In addition, even if COVID Antibodies last 3 years, that would give us plenty of time to develop a vaccine and provide people with booster shots. Am I missing something about B-Cell memory? I've also read articles that describe healthy people who get infected with COVID and die of a cytokine attacks (https://www.sciencemag.org/news/2020/04/how-does-coronavirus-kill-clinicians-trace-ferocious-rampage-through-body-brain-toes). In essence, a cytokine attack is when your immune system is kicked into overdrive. It starts killing off cells indiscriminately, including your own cells. This is what killed so many people during Spanish flu. Young people were at higher risk because they had a stronger immune system. Now, I don't know enough about cytokine storms to answer this question properly, but are scientists worried that the presence of antibodies could cause these attacks? If not, it seems that antibodies should keep one safe from the most serious effects of COVID. My (non-expert) opinion is that scientists won't say that some people are immune out of an abundance of caution. I also think its political. If people know that getting infected leads to immunity, young people will purposely catch the virus. In addition, people with antibodies would be able to leave lockdown, creating more civil unrest. A nytimes opinion article (https://www.nytimes.com/2020/04/28/opinion/coronavirus-antibody-certificate-testing.html) talked about this issue. If people who are immune can return to work, the remaining people without antibodies will be at an economic disadvantage. Would employers ask for your COVID status? Could you lose a job based on whether you can safely return to work? By being ambiguous about whether antibodies keep someone safe, we are not forced to confront these more difficult political questions. I'm interested in hearing your optinion! Remember, I'm not an expert, so take everything I say with a grain of salt. I am looking forward to hearing some expert opinions.

| Posted: 16 May 2020 09:24 PM PDT Are there statics to show this? As a random example, if you're showing general "flu-like" symptoms of having a virus, there's a 50% chance of it being COVID, 30% chance of it being the flu, etc.... [link] [comments]  |
| Posted: 16 May 2020 05:45 PM PDT A piano player needs a lot more finger control than an average person, so I suppose the place where this info is kept takes more space. Other less used functions, like moving your toes, that are stored near it sacrificed to make space? There's evidence that in blind people, the visual cortex is repurposed for language processing, but what happens if they gain vision through surgery? [link] [comments]  |

| Posted: 16 May 2020 05:03 PM PDT In this video by Veritasium (11:24), he claims that a liquid-filled cylinder spinning around an axis with the smallest moment of inertia will dissipate its rotational kinetic energy and eventually change its rotation towards spinning around the axis with the largest moment of inertia, which corresponds to the lowest energy state. However, as I understand, angular momentum is a vector and thus has a direction. If the object is initially spinning around a given axis, its angular momentum points in the direction of this axis (I think). How is it possible then that conservation of angular momentum holds if the axis of rotation has changed? There seems to be some flaw with my reasoning and I'd like to figure out what it is.

| Posted: 17 May 2020 01:26 AM PDT Hi, I can't find a clear answer to this. Maybe it's very obvious, but I need someone to confirm this; if a carrier or essential oil has long chain fatty acids mainly, is it thicker than a oil with mainly short chain fatty acids? Or this the long/medium/short chains have not effect on the thickness/consistency? Thanks! [link] [comments]  |

| Can we detect a Doppler shift (or "wobble") on the Sun from Jupiter's gravity? Posted: 16 May 2020 11:59 PM PDT Can Earth-based Doppler spectroscopy detect the effects of Jupiter's gravitational interaction with the Sun, similar to how it is used to search for extrasolar planets? I assumed that it could, but then it occurred to me that Jupiter's orbital period of ~12 years means that we would only have been able to observe two or three Jovian orbits since usable Doppler spectroscopy emerged in the mid-90s. What about gravitational perturbations caused by Saturn and the ice giants? Their longer orbital periods would certainly preclude their effects on the Sun from being directly observable thus far, right? Do we have sensitive enough equipment now to detect even the terrestrial planets' gravitational wobble effects on the Sun, given their shorter orbital periods (and despite their much smaller masses)? Or is the Sun just too bright from our relatively close proximity to it for us to observe a red/blue shift from the wobble that orbiting bodies cause? [link] [comments]  |

| Why did Saturn V have so many stages? Posted: 16 May 2020 11:15 PM PDT The Saturn V had three full stages, inter-stages, and then the Apollo spacecraft or other craft or similar on top. Why was it so complex? Or is it not actually as complex as I think? [link] [comments]  |
| When did freshwater life evolve? Posted: 16 May 2020 10:11 PM PDT Did freshwater life evolve shortly after marine life or did it evolve after life has transitioned to land? [link] [comments]  |
| How does hearing work in animals with good hearing? Posted: 16 May 2020 07:46 AM PDT I don't think being able to see well can really be a hindrance, and a super sensitive nose probably isn't a big deal either, but what about hearing? If an animal can hear really far/low volumes, does that mean everything at "normal" volume is deafening? Or is it not as simple as a simple multiplier being cranked up? [link] [comments]  |
| Posted: 16 May 2020 05:24 PM PDT Also if a shape is not independant of its dimensions, if it's possible to find the drag coefficient if I do not know the drag force but I do have the drag coefficient of the same shape but with different dimensions? [link] [comments]  |
