| Why are wet things much harder to burn? Posted: 25 Dec 2021 06:11 AM PST Seems like an obvious question but I was discussing this with my kids and we couldn't find a good answer. I'm hoping that the collective brains here can give us a definitive answers. Thanks [link] [comments] |

| Posted: 24 Dec 2021 11:17 PM PST This moment in the documentary fascinated me, where Herzog shows a penguin stopping in its tracks, and suddenly starts walking alone away from its home or hunting grounds towards the desolate mountains of Antarctica, where it will die. He says that the penguin scientist he talked to (though without directly showing us the scientist telling this) told him that, even if they went out and brought the penguin back, he would just go right back to his death march. I really can't stop thinking about it, it's a strangely, somewhat upsettingly, human behavior that, if is how Herzog describes, certainly appears like the penguins are trying to die. But when looking online, I couldn't find any scientific reports of this behavior, only people referring back to the documentary. The scientist seemed like a real scientist, but there's no information on this I could find. Is there any truth to this? Is this a behavior scientists have observed in penguins, and if so is it as bleak as Herzog describes? [link] [comments] |
| Do antibodies get used up when preventing an infection? Posted: 25 Dec 2021 04:14 PM PST Suppose I have COVID-19 neutralizing antibodies from a vaccine. I get exposed to SARS-CoV-2, but neutralizing antibodies prevent the virus from reaching my cells. Does that lower my antibody levels, leaving me more vulnerable on next exposure? Would antibody levels drop for other reasons than this? Can the distinction (if this depletion does occur) be measured? [link] [comments] |
| How do the rapid antigen tests work in depth? Posted: 25 Dec 2021 06:23 PM PST Hi, I was interested in knowing the specifics of how the rapid antigen tests work, I know that they must involve identifying covid antigens but how exactly? I couldn't find any information about them online apart from that they 'are less accurate than the PCR tests.' [link] [comments] |
| What is going on in the bodies of people with asymptomatic Covid-19? Posted: 25 Dec 2021 02:52 PM PST For the approximately 33% of Covid-19 positive people who have no symptoms (but can still transmit the disease), what is actually happening in their interactions between their immune systems and the virus? If they can transmit the disease to others, the virus must be replicating in their cells; why does this not hammer them with the usual symptoms such as coughing and fever? [link] [comments] |
| Posted: 25 Dec 2021 10:12 AM PST I'm trying to understand these old-style eyepieces where there was only a lens and an aperture at the focal distance of the lens. How does one calculate the FOV of the eyepiece? Also known as the apparent field of view of a telescope? e.g. https://www.nexstarsite.com/_RAC/articles/fieldofview.htm#:~:text=The%20field%20of%20view%20is,smaller%20piece%20of%20the%20sky.&text=Usually%20astronomers%20refer%20to%20the,field%20of%20view%20or%20TFOV.

| Posted: 24 Dec 2021 11:52 PM PST I'm aware of certain levels that need to be maintained in the blood but it is my understanding that this is produced internally. If this is the case would it be safe for me to breath air with a theoretical 0/ppm CO2 composition? Relatedly, is there consensus on the optimal proportions of gases to maximize brain function in a typical human and where could I find such information? Thanks! [link] [comments] |
| How do collisions cause diffusion? Posted: 25 Dec 2021 06:41 AM PST Never really understood why random collisions can suddenly drive particles to areas of lower concentrations. Why is this? [link] [comments] |
| Do Cordyceps tap in to the hosts senses? Posted: 25 Dec 2021 01:19 AM PST I was just watching the BBC Nature doco about the fascinating and kind of scary Cordyceps, and how they take over ants, and make them go to an optimum place then clamp their jaws onto the plant stalk and then the Cordyceps start emitting spores and the whole lovely process can repeat. My question is how does the parasite know when the ant is in the position it wants it to be in, before triggering the next stage (the jaw clamp and spores/growing)? Does it actually burrow into the insects brain and live in it now or is it capable of it's control without doing that? [link] [comments] |

| What is the difference between tumor thrombus and tumor thrombosis? Is the latter an existing term? Posted: 25 Dec 2021 01:13 AM PST I couldn't find answers on Google. The term "tumor thrombosis" appears only in papers authored by Asian researchers (translated papers). Hence, I couldn't verify whether it is a proper term and couldn't find information regarding this term. [link] [comments] |
