| Posted: 02 Jun 2021 01:49 PM PDT I trust the results that show that the vaccinea are safe and effective. I was talking to someone who is not an anti Vax, but didn't want to take any covid vaccine because he said it was rushed. I explained him that it did follow a thorough blind test, and did not skip any important step. And I also explained that it was possible to make this fast because it was a priority to everyone and because we had many subjects who allowed the trials to run faster, which usually doesn't happen normally. But then he questioned me about why were the vaccines not fully approved, by the FDA for example. I don't know the reason and I could not find an answer online. Can someone explain me what exactly is missing or was skipped to get a full approval? [link] [comments]  |
| We create vaccines to build long term immune response, why cant we build them to suppress? Posted: 03 Jun 2021 01:06 AM PDT I suffer from pollen, dust, cat, etc. allergies flaring up sneezing and general irritation daily. I can't imagine how tough life must be for people with life threatening allergies.. I've read the immune system is being overly sensitive, so why is it we can't remove targets from the immune system playbook? [link] [comments]  |
| Is it the observing of a particle in quantum mechanics that collapses it or the recording of it? Posted: 02 Jun 2021 03:24 PM PDT There was an experiment where the information of a particle's location from a Double-slit experiment was recorded from a computer and placed inside of an atom. The particle then collapsed when the information was placed inside the atom. So when something observed it, it collapsed. My question is, could the act of recording the information in the computer have interfered with the experiment, causing the collapsing of the particle itself rather than the atom? Computers have atoms in it, why wouldn't the computer's recording set the collapsing off? Why does it need to go into an atom for it to collapse? [link] [comments]  |

| Why Cancer-Patients are not considered a risky group for Covid-19? Posted: 02 Jun 2021 09:36 PM PDT My country has considered Cancer Patients as a non-risk group for Covid-19, but considered "Fat People" as a risk group (the media even said that "fat shaming" cannot get in the way of the vaccine, because it is a "healthy" lifestyle, but risky for Covid-19). As they say in my country: "those are two different measures for the same weight". It's seems not proportional at all. About the Cancer patients, the specialists where strongly against the goverment position, saying that covid-19 might be the final drop on a Cancer Patient's life, leading them to death. It's a risk. Not only my country, but from what I see, people around the world are not considering Cancer Patients as a risk group. At least not strongly saying they are a risk group. The only two things that come to my mind are: 1 - people think that: considering the fact cancer that cancer has a high cause for death in the advanced cases, they conclue that in those cenarios "He has cancer, he is aldery dead. It's not Covid who will kills him"; 2 - people think that cancer patients, who are only in the initial stages, don't deserve vaccines since the risky of death is low. I disagree with both points I pointed out in "1" and "2". 1 seems not logical since, covid might be the "imediate"/"final" factor for their death, and 2 seems fair but ignores that it might depend on the concrete case (Let's not treat melanoma as pancreas cancer). But even it I accepted these points, shouln't we all agree that people under chemotherapy are a risky group? There are scientific factors that make Cancer Patients less a risk group than obesity for the Covid-19? Or in any way, a non-risk group in general for Covid-19? It's the concrete case the real criteria for that person with cancer being at risky? Is only a certain group of cancer patients in the "danger zone"? Wich one? [link] [comments]  |

| Using bond energy from atomic to diatomic state of atoms as fuel? Posted: 02 Jun 2021 11:58 AM PDT Excuse my ignorance on this, I haven't been able to find any answers to this question, and chemistry was not my best subject. I was wondering, outside of cost, is there any reason why we can't just react atomic oxygen with itself to produce O_2 and use it as a completely non harmful fuel for rockets or jets? From what I can tell the bond energy of O2 is 498kJ/mol, compared to water which is the product of reacting 2H_2 with O_2 and has a bond energy of 460kJ/mol. I assume this would mean a more violent reaction from 2O -> O_2, but potentially a more effective one? Thank you so much if you answered this, it's hurting my brain trying to figure this one out.

| Is the platinum strictly necessary for the hydrogen fuel cell reaction? Posted: 02 Jun 2021 07:15 AM PDT The context is I have been asked to make an experiment that ~50 summer campers can do. I thought it would be neat to do the cycle of splitting water into H+O, and then getting power back. However, when I look up instructions for making a hydrogen fuel cell, they all start with 'take 12 inches of plantinum wire', which would cost a few thousand to do with everybody. I did an experiment myself where I did everything with non-platinum wire, and my DMM was reading a 0.4V difference, and I did see something mist-like flowing between the two electrodes. Is it possible that I was getting the reaction, and the platinum is only needed for hydrogen power to be practical, or is it more likely that I was reading something else? [link] [comments]  |
| Are mosquitos good for anything at all? Posted: 01 Jun 2021 08:18 AM PDT I was always told that everything in the animal world had a purpose. Are mosquitos just good for nothing? If they are useless, why haven't we killed them off by now to prevent all the disease they give? [link] [comments]  |
