| Is contagious yawning a cultural/learned thing or is it hardwired into us? Posted: 28 Jan 2021 10:14 PM PST When I see someone else yawn it's almost automatic that I will yawn. Even just writing this made me yawn. But I've noticed that my young children don't do this. So is my instinct to yawn because there is some innate connection in human brains or is this something I do because grew up around would do it and I learned it from them? Maybe another way to ask this would be are there cultures that don't have this? (I've seen pop psychology stuff taking about psychopaths and sociopaths but doing it. That's not what I'm referring to, I mean a large majority of a group not doing it) [link] [comments]  |

| Posted: 29 Jan 2021 05:15 AM PST Are there scientific differences in how EU vs US trials are performed? Does the FDA allow this in exceptional times (like the current pandemic?) [link] [comments]  |

| What is the fate of lipid nanoparticles in certain COVID-19 vaccines? Posted: 29 Jan 2021 05:24 AM PST Relatively little attention seems to be given to the lipid nanoparticle formulations when discussing the safety and efficacy of the new mRNA vaccines. It would seem the lipid nanoparticles are needed to make an efficacious vaccine, but what do we know about the short and long-term fate of these lipid nanoparticles inside the human body?

| Why did Earth's rotational velocity recently increase? Posted: 28 Jan 2021 07:47 PM PST I keep reading that we're thinking of taking away the "Leap Second" this year because Earth's velocity increased in 2020, but I'm seeing little explanation for why that might occur. Some super large rock formation moving around in the lower mantle? Some weird phenomenon in the core? What are the most plausible explanations? [link] [comments]  |
| Posted: 28 Jan 2021 06:34 PM PST Afaik it's commonly accepted in the scientific community that over time pathogens typically become more and more mild. The idea being that you want to still infect your host, as that is essential for survival, but the more you disrupt their ability to survive the less likely you are able to spread and thus survive yourself. In humans there is also the added pressure to evolve this way because we actively combat severe pathogens but don't to nearly the same extent with the more mild ones. A good example of this effect would be something like a common cold. Beyond just being physically different from their ancestor, how are the new strains popping up around the world different? Are they less/more lethal? Less/more infectious? Cause more/less long-term damage? I'm quite curious to see if the phenomenon I described is occuring within the COVID-19 virus, essentially, and if this rule-of-thumb in Pathology is observable in this specific instance.

| Posted: 29 Jan 2021 02:03 AM PST At the start of the vaccin trails I read many times on reddit that the chance for the trials to fail is larger than success. But since then I haven't heard of any failed trials and cancelled vaccin research. Were there any vaccine researches that were cancelled? And how is it possible that the most talked about vaccin researches all succeeded? Were the numbers people gave at the beginning regarding the chance of such trials to fail false? (Sorry for bad formulation, English is not my first language) [link] [comments]  |
| Posted: 28 Jan 2021 07:24 PM PST I am talking about stars here. Photons are generated in the core and then get emitted and then get absorbed and expelled by nuclei and protons in the radiation zone, however once it reaches the convection zone then it gets absorbed and the energy stays with the particle until it hits the surface. I am wondering why this happens. [link] [comments]  |
| Are carbon dating methods reliable? Posted: 28 Jan 2021 07:42 PM PST Hello everyone. I'm new to this subreddit, but I have a question. Is carbon dating reliable? I have heard many rebuttals from young earthers who claim things such as: *water (a flood) tampers with carbon dating methods *rocks where we know the age (i.e formed in an eruption or lab made) date millions of years old *carbon levels were not always the same I am not a scientist, so this video has me stumped. Any and all answers are appreciated. Thanks! [link] [comments]  |
| Why do viruses make you sick ? Posted: 28 Jan 2021 09:33 AM PST The only goal of a virus is to multiply. Making you sick does not help that goal. Killing the host will kill all the virus in it also. So why have most viruses not evolved to harmlessly enter their hosts? [link] [comments]  |
| What is the relationship between vomiting and brain injuries? Posted: 28 Jan 2021 08:45 PM PST Traumatic brain injuries have vomiting as one of their possible symptoms. What is it about brain injuries that trigger vomiting? [link] [comments]  |
| Why do ion thrusters produce so little thrust? Posted: 28 Jan 2021 08:51 PM PST What law of physics forbid it from having higher thrust? [link] [comments]  |
| How is a magnetar formed compared to a neutron star? Posted: 28 Jan 2021 01:26 AM PST So I think understand that a magnetar is a form of neutron star and both are created by the collapse of a larger type of star, but what causes one to be a magnetar specifically? Is it related to the entropy of that specific star car similar to what I was reading in a previous post? Or is there something I'm completely misunderstanding? [link] [comments]  |
