What is P- hacking? |
- What is P- hacking?
- I recently learned COVID has a lipid membrane but I was taught in school that viruses are DNA or RNA packed inside a protein shell, so how many different virus physiologies are there and what exactly is COVID made out of?
- What happened to herd immunity?
- Is a third vaccine justified by sinovac vaccines?
- How will cooling as a result of the AMOC current stopping interact with general global warming?
- How are COVID virus mutations named (letters and numbers) and what is the difference between a "mutation" and a "variant" (Greek letters)?
- How is having mRNA injected through a vaccine different to consuming an animal or plant? Do we not consume mRNA each time we eat?
- Is there a -- and if so, what is the -- "feedback" mechanism from the bladder to the kidneys? (Is there a message like, "Stop already!!"?)
- how do radiolarians form their skeletons?
- How common are reinfections and breakthrough infections?
- Why is it that when we yawn we can’t hear anything?
- The origins of HIV were recently discovered in a group a chimpanzees, did the virus cause AIDS in the Chimpanzees?
- Is the Ort Cloud spherical?
- Why does a brain’s surface area matter so much?
- Does the brain learn more when it succeeds or when it learns from a failure?
- Why does biological matter not rot under specific circumstances?
- Does the glycocalyx protect the blood vessels against glycation stress from high blood glucose? Can it be regenerated even after glycation?
- Did the Columbian expeditions bring diseases back to Europe?
- Are there any animals that are both poisonous and venomous?
| Posted: 06 Aug 2021 03:23 AM PDT Just watched a ted-Ed video on what a p value is and p-hacking and I'm confused. What exactly is the P vaule proving? Does a P vaule under 0.05 mean the hypothesis is true? [link] [comments]  |
| Posted: 05 Aug 2021 10:26 PM PDT As the title said, I was taught that viruses are a protein shell with a DNA packed in that inject their DNA (or RNA) into the host cell. Now I learn that some viruses actually have membranes and multiple membrane proteins, which is much more complex than the image I have in my mind. Now I'm wondering about how many different phenotypes of viruses there are, is it a binary thing, some are a protein shell and some are a membrane, or more of a spectrum? Do we know?

| What happened to herd immunity? Posted: 05 Aug 2021 08:37 AM PDT In the beginning of the pandemic there was lots of talk about reaching herd immunity but as the delta variant ravages throughout the world, it seems that all talk about herd immunity has ceased. Why is that? Or am i just misconstruing the situation? [link] [comments]  |
| Is a third vaccine justified by sinovac vaccines? Posted: 06 Aug 2021 03:50 AM PDT There has been rumors about a third vaccine shot to boost the effectivity of Sinovac vaccine . So; A- is this being actually applied in countries where they have been using Sinovac vaccines for the first two shots? Have they started giving the third Sinovac shots now ? B-Is combination of a different vaccine as the third shot scientifically proven to be effective? As an example the first two shots = Sinovac, but the third shot=Pfizer. C-Are other combinations possible , like pfizer + astrazeneca etc ? Whats the current scientific consensus on this ? Thanks in advance Edit: This is the only research paper i could find so far https://www.medrxiv.org/content/10.1101/2021.07.23.21261026v1 [link] [comments]  |
| How will cooling as a result of the AMOC current stopping interact with general global warming? Posted: 05 Aug 2021 01:57 PM PDT This article says that if this ocean current stops, it could make parts of the northern hemisphere colder. Would that mean just colder winters, or year-round? Would there still be more heat waves in summer? Would it make equatorial regions even hotter? [link] [comments]  |
| Posted: 06 Aug 2021 12:49 AM PDT There are 'mutations' of the COVID 'delta variant'. P681R increases the viral load. Mutation D614G is thought to make the SARS-CoV-2 virus' spike protein more dense, and could help the virus more easily invade cells and evade the body's defenses. Mutation L452R may perform a similar function by thwarting antibodies. At what point does the 'delta variant' become the 'epsilon variant'? Is it the collective number of mutations that define a variant? [link] [comments]  |

| Posted: 05 Aug 2021 12:02 PM PDT Like normal humans, I wake up in the morning, put on my glasses, and take a humongous morning pee. It has not been an emergency to get to the bathroom; I am not in pain; etc. Thing is, I can void nearly the same volume an hour later. It's almost like, say, at 3ayem the bladder told the kidneys to take a break for a few hours, then later called them back to work to "finish the job" -- which results in the large volume of the second trip. Is there a special nerve for handling this situation? Some special fast-acting enzyme that makes it back to the kidneys via the bloodstream? What? [link] [comments]  |

| Why does a brain’s surface area matter so much? Posted: 06 Aug 2021 04:02 AM PDT Wouldn't a smooth brain have a higher internal volume than a wrinkled brain and a slightly higher neutron capacity? [link] [comments]  |
| Does the brain learn more when it succeeds or when it learns from a failure? Posted: 05 Aug 2021 11:13 PM PDT I am getting conflicting answers: We learn more from success because when we succeed at something we already know, it reinforces the connections between our neurons, and when we succeed at something new, it sticks with us because it's novel. Success also activates our reward system, which makes our brains want to keep succeeding at that thing. You can use muscles as a metaphor: Every time you use a muscle, it gets stronger, just like every time we use our brains, the connections between our neurons get stronger. We learn more when we fail and take the time to understand why. This is because when we realize that we did something wrong, our brains put in extra effort to strengthen neurons that make the correct associations. You can use muscles as a metaphor: If you want to grow a muscle, you have to stretch and strain it. You don't do things that are easy for your muscles to do. You do things that your muscles struggle with. This helps your muscles grow stronger. The same goes for your brain. The more you fail and learn, fail and learn, the stronger it gets. Maybe one is true but the rationale used isn't accurate. I think it's funny that both ideas use a muscle metaphor. [link] [comments]  |
| Why does biological matter not rot under specific circumstances? Posted: 05 Aug 2021 11:23 PM PDT I know this is an odd question but the item in mind that brought the question up was egg tempera. Egg tempera is a primitive form of ink composed of egg yolk and pigments. Egg yolk decomposes and rots over time, correct? We all know how bad rotten eggs smell. So why then does egg yolk not rot when it's made into egg tempera? In theory, shouldn't the ink decompose over time and lose its composition as the egg yolk breaks down? As far as I know, the egg yolk itself is still biological in nature, so why does adding certain chemicals suddenly make it stop decomposing? Upon further reading, I see that egg tempera can "rot" if not handled properly. But, if handled properly, it's considered stable, permanent, and unable to decompose. So what prevents the decomposition there?? Another example is animal glue, glue made from melting animal hide. It is 100% biological material that doesn't necessarily show decomposition. Why not?

| Did the Columbian expeditions bring diseases back to Europe? Posted: 05 Aug 2021 04:55 PM PDT My apologies if this question has already been asked, but it seems as though the focus of disease transmission in the Columbian expeditions goes from the Europeans to the Americans, rather than the other way around. Did any diseases make it back to Europe? Is it something like, whoever was going to die of these diseases died in North America, and people who could survive them made it back with some level of immunity and without the ability to transmit?
