| Posted: 15 Jul 2022 07:48 AM PDT It seems a reasonable hypothesis that a portion of the "problems" with an aging immune system come from aging stem cells in your bone marrow. Obviously bone marrow extraction is very painful, but other than that hurdle, is there some reason I am not seeing that storing your own bone marrow on LN2 for later wouldn't be a way to restore the "youth" of your immune system later on in life?

| Posted: 14 Jul 2022 04:10 PM PDT The reports of the illness I read in 2020 were typically along the lines of "holy shit that was awful!" and this summer, I get much more muted reports. Does the large-scale data collected by public health reflect my own personal/anecdotal impression? Also, is there data providing any sign that rates of mortality, and chronic, post-infection complications are reduced this summer? [link] [comments] |
| Posted: 15 Jul 2022 01:41 PM PDT Not sure if I worded the title correctly, but I was wondering how antibodies and resistance to Covid works. Take, for instance, my experience with the virus…
If your body produces antibodies after infection, is it possible that continued exposure to Covid would ensure your body continues to produce antibodies? Why would continual exposure to Covid not act similarly to a booster? [link] [comments] |

| How are plants in greenhouses pollinated? Posted: 15 Jul 2022 01:23 PM PDT e.g. tomatoes, cucumbers. Do they bring in bee hives? [link] [comments] |
| How old are the pillars of creation? Posted: 15 Jul 2022 10:57 AM PDT I'm trying to find out more about celestial nebulas and ai read that the pillars of creation may already have been destroyed at their location 7000ly away, but how old are they? It doesn't say anything about how long they've been swirling about for, neither on Wikipedia, nor on their NASA website. Is it something we can't say for sure? [link] [comments] |
| How do we know that a 3rd or 4th booster is helpful? Posted: 15 Jul 2022 04:10 AM PDT Do we have data to backup saying that a 4th dose will reduce hospitalization for someone under 50? Are the memory B and T cells no longer active? I am so confused by the messaging from the thought leaders because I thought that part of the immune system had long term memory [link] [comments] |
| How reliable is the DNA molecular clock? Posted: 15 Jul 2022 06:42 AM PDT I was reading the rise and reign of the mammals by Steve Brusatte, and in it he says we can calculate species divergence by looking at the DNA, and calculating how long that much difference from each other must have taken given DNAs rate of change. How true is this? Is the rate of change the same in all animals/bacteria/etc.? Wouldn't the average age of reproduction of a species change this or no? [link] [comments] |
| Posted: 15 Jul 2022 06:45 AM PDT If a non-blind person sees a given familiar object (e.g., a dog on the street), they immediately "know" what that object is, even before the word describing the object (e.g., "dog") in a given language "appears" in consciousness. Is it understood why this delay occurs and what the link between the brain's ability to perceive a given object, and then recall its lexical term is? In a broader sense - where and how does the link between vision and language occur in the brain? [link] [comments] |
| Why does COVID produce neurological symptoms and is it common for viruses? Posted: 14 Jul 2022 11:23 PM PDT I've wanted to ask this question since the pandemic began. I don't remember hearing of many viruses that cause neurological systems (like loss of scent/taste) but I'm not a biochemist or virology expert. [link] [comments] |
| (Geology) Could the North and South American continents have remained separated? Posted: 15 Jul 2022 05:48 AM PDT North American and South American continents remained separated until 3 million years ago, when Panama formed, uniting the two continents. This then resulted in migration of animals from North America into South America, causing some of the South American as well as sea animals like Megalodon to die out. I was wondering if it was possible for the two continents to never unite, thus some of the strange ancient animals could have survived longer, possibly until modern day? [link] [comments] |

| Why do some mammals move their nose/nostrils when they breath? Posted: 15 Jul 2022 11:47 AM PDT As comparison, humans have no movement associated with the nose when they breath. How are animals/mammals different? Do they have muscle responsible for breathing other than the ones in their chest? [link] [comments] |
| How many stars exploded in order to create the Carina nebula? Posted: 14 Jul 2022 06:14 PM PDT I just saw this post: https://reddit.com/r/jameswebb/comments/vysbxk/in_the_highresolution_image_of_carina_the_size_of/ And it made me wonder. How many stars exploded to create this nebula? Or was it formed through some other process? Given how large this is, it's hard for me to imagine that one star could create something like this?

| How can an electric sparker ionize air with such low voltage? Posted: 14 Jul 2022 08:32 PM PDT According to google the piezoelectric sparkers used for things like barbeque lighting have a voltage of around 800 volts, while air has a breakdown voltage of ~30k volts/cm, yet an electric sparker can still easily create an arc over half a centimeter of air. How is this possible? [link] [comments] |
| Did proto-bears have long tails? Posted: 15 Jul 2022 03:24 AM PDT Is there in the fossil record any bear ancestor with a long tail? [link] [comments] |
| Are there multiple independent measurement of the universe’s age? Posted: 14 Jul 2022 03:26 PM PDT I understand using redshift data to back out when the Big Bang occurred. Can we instead use Cosmic Microwave Background (CMB) data to determine the universe age, without using redshift data? [link] [comments] |
| How does drying pasta actually work scientifically? Posted: 14 Jul 2022 06:29 PM PDT So from my understanding, commercially dried pasta is dried using hot air and then cool air somehow to remove moisture. But my question is how this works, like on a chemical level. Like how does this not just bake the pasta? If I made pasta at home and tried to dry it, it wouldn't end up the same as the theoretically everlasting dry pasta that you get at the grocery store. What's actually happening to the pasta when it dries? [link] [comments] |
