| Does more exposure to a virus make you sicker? Posted: A few months ago, there was a meme about how all of the COVID virus in the world would be able to fit into a tablespoon, and the meme was about someone eating it (very silly, yes). But that got me thinking about what would happen if that was possible. Does more exposure to a virus cause you to get sicker, or would the immune response be the same? Maybe as a side question, would the person from the meme (assuming they were healthy and wouldn't have died from COVID normally) have died from that much exposure? [link] [comments]  |
| Posted: Hello, sorry if it's a stupid question but I'm really curious. I saw some article about how Perseverance is powered and it's really interesting. I understand that a car might require a bigger reactor but still, would it be possible to have it charge the vehicle's batteries as you go? If it would be possible, would it actually be a better option that having to charge every few hundred miles? [link] [comments]  |
| How do you quantify relative amounts of DNA? Posted: I was recently reminded of an article where a lab in Canada claimed that around ~50% of subway chicken is actually soy. They claimed that quantification was done but amplifying DNA with PCR. I have a background in biology, neuroscience, micro biology, molecular bio. How do you use PCR to calculate these percentages?https://www.cbc.ca/news/business/subway-defends-its-chicken-after-cbc-marketplace-report-1.4005268 [link] [comments]  |
| Posted: Lets say, hypothetically, we show a picture of a cat. then let the subject picture the cat in their 'minds' and we take the brain signals as data set. Repeat it thousands of time, then we have a feasible data set to feed into an AI to figure out what brain signal correlates to what is imaged. [link] [comments]  |
| Posted: If the purpose of two shots is to increase the efficacy and long term staying power of the antibodies, then could you theoretically get as many vaccine doses as you wanted? Would this be helpful for protecting from COVID? Would it be harmful? Is there a diminishing return after a certain point? [link] [comments]  |
| Posted: I was reading about poliovirus because I didn't really know anything about it beyond its prevalence in the early half of the 20th century and it paralytic effects (it's super worth reading up on if anyone is in the same boat). I was surprised to learn that the poliovirus is mainly transmitted through a fecal-oral route, and that improved sanitation systems actually led to the serious outbreaks in the US and Europe because people weren't getting exposed as much and thus hadn't built immunity. I read an interview with a polio historian guy who was saying how important it is to continue to fight polio in the 3 countries it's still endemic in to keep it from spreading. He also talked about the dangers of the rise in vaccine skepticism as, if our vaccinated levels drop here in the US for example, it could open the door to polio outbreaks in the future. Really? Is there like an acceptable amount of fecal matter in our drinking water, I wondered. But no, according to current guidelines " For every 100 mL of drinking water tested, no total coliforms or E. coli should be detected." Obviously, let's just keep up with our routine immunizations, but is it possible for polio to spread under our current water systems in the US as well as other developed nations? [link] [comments]  |
| Do animals discriminate based on appearance? Posted: We all know that animals sometimes use physical features to chose a mate, a song, colors, a dance. But, outside of mating, do animals discriminate based on appearance? We see interesting pictures here on Reddit every day, the albino giraffe, the turtle that has somehow survived the shark attack, though is greatly scarred. . . do these animals face any ramifications in their social interactions with others of their species? "You look different, so you are not allowed to be part of our pack" type thing? [link] [comments]  |
| Do Hermit Crabs Grow The Shells They Live In? Posted: If hermit crabs exchange shells when they grow too large for their current one, what is growing the shells in the first place? Is it another species of crustacean that dies off and the hermit crabs inhabit the homes? Or do the shells grow with the hermit crabs for a time before they seek a larger one? [link] [comments]  |
