  1. There was nothing self righteous about my attitude, nor anything that justified the hostility with which you responded. There are plenty people who responded here and save for one other person, you were the only one who couldn't do it in civil fashion. But anyway, let's drop it, I would rather get more good information than debate whether you should respond to people politely on internet forums.
  2. I'm genuinely curious as to what the cause is for the hostility? I've asked for information in the interest of educating myself, am I not allowed to hear all the evidence before making a decision?
  3. I work from home so during this whole ordeal the world's been having with COVID, I've been blissfully and irresponsibly ignoring it, but now I've been called up to take the Pfizer vaccine, so I actually have to educate myself a bit. I've been watching this video on data from Israel about side effects associated with the Pfizer vaccine (which I'll link to at the bottom) and they mention severe side effects (but don't specify beyond that), albeit very rare. Now, I'm thinking, the vaccine has at this point been tested on a large number of people, but without long term followup, whereas
  4. When a person is infected, survives and develops immunity, can they still transmit the disease to others? If no, how long after the infection before the person becomes a non-transmitter? I assume this varies, but what are some general timeframes?
  5. I did the search and it seems like this approach of programming T cells was already in use in fighting cancer before the big announcement from the Scottish team. So what did those guys exactly innovate and does this has prospects of being a cure or just a therapy?
  6. There was that report I think earlier this year about a team of Scottish researchers who'd, IIRC, reprogrammed t-cells to attack only cancer cells and cured cancer in mice. Have there been any new developments on that?
  7. TL DR: Is there anyone here knowledgeable about endocrinology, specifically hormone receptors, blocking them and upregulation? I'm wondering if you could tell me what is known about how receptor blockers cause regulation, specifically how long must you block a receptor in order to induce that response and how you might avoid that. THE LONG STORY: This relates to a potential anti-hair loss drug that runs into a problem related to this. The story is this: Clascoterone is being developed as a potential drug for treating male pattern baldness under the name Breezu
  8. If I understand the argument correctly, it's that if you compare a set of all whole numbers to a set of all whole + half numbers, when you look at each set up to number 2, set 1 would be 1 and 2 (and 0?) and set 2 would be 1/2, 1, 1 1/2 and 2 - so set 2 has more numbers, but that's only if you look up to 2. If you look at the whole sets the size of each is infinite, so neither is bigger than the other. What am I missing here?
  9. All the typical weirdnesses of QM - the double slit experiment, observation collapsing the wave function etc. - are they still regarded as mysteries that need to be resolved, or is the view now that that's just how the universe is and there is no explanation beyond that?
  10. Have there been any great scientists since the 20th century who were religious? And I mean religious in the conventional sense of believing in some major religion, not religious in the kind of unorthodox way Einstein was.
  11. I think that was just one of the speculated hypotheses, I don't think the mechanism of action was known, but now Follica says microneedling induces the generation of new hair follicles through stem cell division. My concerns are the ones outlined in this video and I'm wondering if anyone is knowledgeable enough on this topic to tell me whether this is a realistic concern, given stem cell division in generation of new hair follicles
  12. I learned about it from a company called Follica which is developing a hair loss treatment. Here's an article summarizing the results they announced. I don't know whether there's independent research that found hair follicle neogenesis, but there is research showing microneedling induces hair growth in balding men.
  13. If you're unfamiliar with it, microneedling is a proceedure used for skin rejuvenation (including removing scars) and hair loss. A device is used to create many many tiny needle puncture wounds on the skin or the scalp. It's something htat is becoming increasingly popular, but it seems to me, with my limited knowledge, that there might be some cancer concerns here through two distinct mechanisms: 1) What is described here starting with the header "Dermarolling May Trigger Tumor Formation" 2) generation of new hair follicles through stem cells When used on the scalp, microneed
  14. #1 If you have a sphere with an axis through it around which it rotates, is the number of possible axis it can have finite or infinite? #2 This is maybe the same question in a different way, but what's got me confused is this: Is the number of possible positions (for a point) on a finite line finite or infinite? Because the way I'm thinking about it, you can take a point and put it a certain distance from one end of the line and then you half the distance and get another position and you half it again and again... you get the idea, you can half it an infinite number of times, which s
  15. I was reading this Quanta article https://www.quantamagazine.org/how-nature-defies-math-in-keeping-ecosystems-stable-20180926/ And the following quote appears in it: “People have made a lot of progress in genetics by studying model organisms,” Can someone give me an example of progress being made in genetics by studying model organisms or explain in principle how progress is made by studying model organisms?
