Can a dormant herpes virus become active if someone is in contact with cold sores? Posted: 07 Jul 2022 11:07 PM PDT I've read that most of the world population already has herpes (something like 80-90%) but only a small minority show symptoms (cold sores). In the case of HSV-1 virus, if someone already has the virus, but is asymptomatic (never had any outbreaks, as seems to be the case with most of the population) and gets into contact with cold sores (from a partner), will that person develop symptoms (cold sores) or will the virus continue to be dormant? submitted by /u/parkix [link] [comments]

What causes the hours-long delay between a vaccine injection and the onset of immune responses symptoms (chills, etc.)? Posted: 07 Jul 2022 11:36 PM PDT I've gotten seven vaccines in the past year or so and it seems that although I feel fine immediately after the injection other than a slightly sore arm at the injection site, after about 9-12 hours the immune symptoms begin to kick in. Chills, fatigue, and generally feeling out of sorts. What specifically is happening during that interval? submitted by /u/9183b_34834 [link] [comments]

Was junk DNA always junk or is it vestigial? Posted: 07 Jul 2022 11:56 AM PDT I know that random mutations will produce "nonsense" and assume that at least some of the "junk DNA" we carry can be attributed to that, but I was wondering if some of it are fragments of vestigial DNA from our distant ancestors? If it exists, can we tell the difference between those two categories of DNA and has any of that vestigial DNA been traced to its origin? I'm imagining that it's possible that we and chimpanzees share some junk DNA that's been hanging out since our ancestors diverged a relatively short time ago. Is this true? Thanks. submitted by /u/LurkerFailsLurking [link] [comments]

How much would a COVID variant have to mutate before current COVID tests wouldn't properly detect it? Posted: 07 Jul 2022 02:12 PM PDT Like how the current batch of vaccines didn't protect against infection from the Omicron variants, could a variant sufficiently mutate to not be able to be detected by either a PCR or an antigen test? And if it reached that point, would it still be COVID 19, or instead of evolved to the point where it probably deserves a different name? submitted by /u/darthjoey91 [link] [comments]

Why do some plants bloom for only one night? Posted: 06 Jul 2022 11:44 PM PDT There are a number of plants that bloom for just one night per year. It seems reasonable to think that a mutated variant blooming for two nights would eventually out-compete the one-nighters, but since that hasn't happened I guess that's not the case. Why? submitted by /u/PremiumPrimate [link] [comments]

Why are some lakes clear and others murky? Posted: 07 Jul 2022 01:31 AM PDT Even if the water is still. Won't all the sediment settle to the bottom eventually and become clear. submitted by /u/ProtagonistForHire [link] [comments]

Are plastic containers (with or without BPA) relatively safe as long as they're not used to store/heat up food? Posted: 06 Jul 2022 07:04 PM PDT I'm into organizing, and plastic containers, storage boxes, and trays are the most commonly available items for that. I've recently become aware of the dangers of BPA (Bisphenol A), as well as BPS (Bisphenol S) (which is not flagged equally but considered just as dangerous) as endocrine disruptors and carcinogens. I've learned that it is strongly recommended to replace plastic when it comes to food containers. However, I have a few questions about the use of plastics in every day life that I have found opposing answers for when searching and I'd appreciate your take on: Are plastic containers relatively safe (with or without BPA) as long as they're not used to heat up food? Is not using them for storing food in the fridge or at room temperature still highly recommended or are the risks exaggerated? Do plastic containers/trays/storage bins (with or without BPA) for clothes, personal items, and paper pose similar risks? Should plastic be avoided to store and organize items in desks, closets, shelfs, etc, too? Do the risks of doing 1 and 2 increase for a person with actual hormone problems? submitted by /u/fullsunset [link] [comments]

Does produce absorb pesticides directly or though water? Posted: 06 Jul 2022 07:59 PM PDT So eating pesticides isn't good. I wash my stuff in baking soda usually to try to get off what I can. I'm curious however if plants absorb pesticides directly into their flesh? For example avocado... can you spray avocados with pesticides all you want and it will be safe to eat because you are removing the thick external cover? Or will the pesticide leach into the water, and then be absorbed by the plant, then eaten by you? Or does it perhaps get absorbed directly through the skin? Just curious! submitted by /u/mikesalami [link] [comments]
