| Posted: 13 Dec 2020 05:05 AM PST Is there a mathematical formulation of a law of cooling that allows both objects in thermal contact to change temperature? The formulation that I learned in high school (Newton's law of cooling) assumes that one of the objects stays at a constant temperature. Assuming that these two bodies are completely isolated, is there a formulation that gives change in temperature as a function of time for two bodies whose temperatures are non static?

| Posted: 13 Dec 2020 07:42 AM PST All this talk of viruses and antibodies has me wondering if this scenario could occur. I know that sometimes autoantibodies are produced, but what if the correct antibodies to the virus are destructive to the host? Also, is there some mechanism for the immune system to know not to go down that path if it is self-destructive? [link] [comments]  |
| Could work on the Covid-19 vaccine end up giving us a vaccine for common colds? Posted: 12 Dec 2020 04:49 PM PST I mean, if you target a sequence that's common in many corona viruses, would this work? [link] [comments]  |
| Posted: 12 Dec 2020 02:06 PM PST I've seen the adalimumab Humira commercials for a couple of years know (I think, or maybe 2020 just really has been the longest five years of my life). But lately I've seen all kinds of other medicines being advertised that end in the -umab suffix. Is it from a particular chemical formula/compound family, or a particular pharmacological lab? Do they all have similar uses or functions? [link] [comments]  |

| How do human brains detect false irregularities in faces? Posted: 12 Dec 2020 07:45 AM PST With false irregularities in faces, I mean aspects of for example deepfake faces or photoshopped faces which leave irregularities that are not normal for a human face (for example weird lines around eyebrows in deepfakes or colour irregularities in the face).

| Is anyone able to tell me the main differences between these two family's of virus? Posted: 12 Dec 2020 03:32 PM PST Coronaviridae: the family to which SARS-CoV-2 belongs, and Orthomyxoviridae: the family to which influenza viruses belong. Specifically what is it which makes a flu virus being to the latter and not the former, and the COVID causing Virus belong to the former and not the latter; what is it which makes these two families distinguished. People often try to claim that the current disease COVID-19 is simply just the Flu - we know this is incorrect and they are two distinguished diseases - and in fact they are even caused by viruses that belong to two entirely different families; I'm interested in explaining what makes these families different - given that, granted, the diseases they cause in these cases are indeed remarkably similar. Any help would be appreciated! :) [link] [comments]  |

| Is it possible the COVID vaccine that produced HIV antibodies could be an accidental HIV vaccine? Posted: 12 Dec 2020 03:24 PM PST I'm referring to this It produced false positives for HIV antibody screens, and apparently in a significant amount of people, so they abandoned the vaccine. But this leaves me wondering where this could be a potential HIV vaccine. Why am I wrong? As I assume the researchers would have thought of that and I just know nothing. [link] [comments]  |
| Posted: 12 Dec 2020 05:14 AM PST I find that animal and fungal evolutionary relationships are for the most part intuitive. The relationships between plants, on the other hand, seem to me a lot less obvious. I have been surprised to learn that small and seemingly inconsequential morphological features such as the number of petals and pollen furrows says more about evolutionary relationships than whether a plant is a tree or a herb, or the shape of the leaves. For example... The horse chestnut (Aesculus hippocastanum) and the sweet chestnut (Castanea sativa) are in different orders (Sapindales and Fagales), yet produce very similar nuts. The horse chestnut tree is in the same family as the baloon plant (Cardiospermum halicacabum), which is a climbing plant. Similarly, Hazel nuts are in the same family as the alder tree, but its nuts look more similar to those of the Oak. I understand that convergent evolution can cause unrelated plants to evolve similar features. But I find these events of convergent and divergent evolution to be much more common and dramatic in plants than in animals and fungi. It appears to be the norm rather than the exception! I am having a hard time understanding why. It is that these phenotypes that I consider to be "dramatic" are actually controlled by surprisingly few genes? Is hybridization is a major driving force in plant evolution (maybe an ancestor of the alder and the oak tree hybridized to form the ancestor of the hazel tree)? Or are there some other important factors at play? [link] [comments]  |
| Why was the m87 black hole chosen to get a picture of? Posted: 12 Dec 2020 04:16 AM PST The m87 black hole is 50 million light years away. Why is it still a better candidate for observation than nearer black holes? Why can't we study our own galactic nucleus? [link] [comments]  |

| Can moisture droplets carrying Covid evaporate, leading to aerosolized Covid? Posted: 12 Dec 2020 08:15 PM PST Some moisture droplets are small and should evaporate easily. The answer is my head is an obvious yes and I'm assuming there is already literature about it, not just for Covid. Edit: There is already literature about it specifically. It seems it can be a large part of how it transmits. Makes me think it was kinda short sighted how aerosolization was argued against in the beginning-mid of the pandemic. Keeping up so others may learn. [link] [comments]  |
