How does tomato juice remove smells? Why is it more effective than many other natural and synthetic compounds? Posted: 19 Jul 2022 07:33 AM PDT Edit: Should have posted this to r/nostupidquestions! Turns out, tomato juice is NOT more effective than many other natural and synthetic compounds. Damn you Spiderman (The Spectacular Spiderman, 2008) for inspiring this question after a fight at the dump. submitted by /u/seaflans [link] [comments]

What's the most massive black hole that could strike the earth without causing any damage? Posted: 19 Jul 2022 09:30 AM PDT When I was in 9th grade in the mid-80's, my science teacher said that if a black hole with the mass of a mountain were to strike Earth, it would probably just oscillate back and forth inside the Earth for a while before settling at Earth's center of gravity and that would be it. I've never forgotten this idea - it sounds plausible but as I've never heard the claim elsewhere I suspect it is wrong. Is there any basis for this? If it is true, then what's the most massive a black hole could be to pass through the Earth without causing a commotion? submitted by /u/Syscrush [link] [comments]

Do elastic arteries follow Bernoulli’s principle? If not, why? Posted: 19 Jul 2022 06:49 AM PDT Okay, so this is a doozy. I was basically having a doubt in the physiology of blood pressure and arteries and my professors were unable to completely answer it, but they gave the reason as 'the large elastic arteries do not follow Bernoulli's principle'. I'm not satisfied with this explanation but as they are not physics professors they just made me accept it as such. So I'm flairing this as physics, but it could be that they misinterpreted my original question which is kinda complicated. So is it true? And why? submitted by /u/DoubleZOfficial07 [link] [comments]

Why don’t the ‘cos’ ends of viral DNA bind inside the capsid? Posted: 19 Jul 2022 08:03 AM PDT So, the DNA within the head of a capsid such as a lambda particle have these extensions at the 5' strand of each end, called 'cohesive' or 'cos' ends. Apparently, they don't bind to each other during packaging and they don't bind to each other while bundled up inside the capsid. Once released into the host cell, however, they have no issues finding and then binding to each other. Why is that? submitted by /u/plectinresearcher [link] [comments]

is it true that one of the effects of puberty is the rapid growth of the brain? Posted: 19 Jul 2022 07:04 AM PDT So one of the effects of puberty is the rapid growth of the human body BUT is it true that one of the effects of puberty is rapid growth of the brain? Because I read somewhere that one of the effects of puberty is rapid growth of the brain Please when you answer send me the scientific paper / source that you got the answer from submitted by /u/mrpotato4565alt2 [link] [comments]

How does wood glue work? Posted: 18 Jul 2022 11:46 PM PDT I understand how glue works but wood glue seems to become a permanent piece of the wood after it's used sometimes lasting hundreds of years. Just curious what's going on there chemically. submitted by /u/glock2glock [link] [comments]

What is stopping scientists from adding more and more neutrons to an atom to create an infinite amount of isotopes? Posted: 19 Jul 2022 04:40 AM PDT I understand that at a point, more neutrons do not 'stick' to the nucleus, but why? What is stopping them from doing so? Why is it not possible to get an infinite amount of isotopes? submitted by /u/EGKMRF [link] [comments]

How do train tracks withstand hot and cold temperatures? Posted: 19 Jul 2022 09:10 AM PDT In the UK, Network Rail explained why the UK rail infrastructure is unable to cope with hot temperatures, however, it also said that 'If we stressed our rails for exceptionally hot weather, they wouldn't be safe for the winter and we'd have broken rail because it's too cold.' What I'd like to understand is how the rail infrastructure in places that do experience extreme sides of weather is able to withstand the extremes. In my head I'm thinking of cities in North America on the east coast which experience very low and very high temperatures. How does their rail infrastructure cope with extremes? How are they built differently? submitted by /u/cosulytt [link] [comments]

How do captive-bred reptiles become salmonella carriers? Posted: 18 Jul 2022 11:47 PM PDT Allegedly 90% of reptiles carry salmonella. Where do captive-bred reptiles pick it up if they're hatched in incubators and away from the poop of older reptiles? Is it passed on during the formation of the egg? Or can it just survive for so long on water/surfaces that it's just a matter of time until they do? What about the remaining 10%, why don't they get it? submitted by /u/Ohsa [link] [comments]

What is the process through which physical/mineral sunscreens (the ones that block with titanium/zinc oxide) lose their efficiency within a few hours? Posted: 19 Jul 2022 01:20 AM PDT If I understand correctly FDA has a ban on claiming more than 2 hours of protection regardless if its a chemical or physical sunscreen - but I would assume that without swimming/washing the physical ones should work longer as the oxides do not break down due to sunlight? submitted by /u/prookyon [link] [comments]

Has the gene frequency of Tay-Sachs disease in humans decreased since screening began in the 70s? Posted: 18 Jul 2022 10:26 PM PDT Genetic testing for Tay-Sachs begin in the 70s. Since then the incidence of Tay-Sachs has fallen by more than 90 percent among Jews, thanks to a combination of scientific advances and volunteer community activism that brought screening for the disease into synagogues, Jewish community centers and, eventually, routine medical care. Until 1969, when doctors discovered the enzyme that made testing possible to determine whether parents were carriers of Tay-Sachs, 50 to 60 affected Jewish children were born each year in the United States and Canada. After mass screenings began in 1971, the numbers declined to two to five Jewish births a year, said Karen Zeiger, whose first child died of Tay-Sachs. Tay–Sachs disease is a genetic disorder that results in the destruction of nerve cells in the brain and spinal cord.[1] The most common form is infantile Tay–Sachs disease, which becomes apparent around three to six months of age, with the baby losing the ability to turn over, sit, or crawl.[1] This is then followed by seizures, hearing loss, and inability to move, with death usually occurring by the age of three to five.[3][1] Less commonly, the disease may occur in later childhood or adulthood (juvenile or late-onset).[1] These forms tend to be less severe,[1] but the juvenile form typically results in death by age 15. Tay–Sachs disease is caused by a genetic mutation in the HEXA gene on chromosome 15, which codes for a subunit of the hexosaminidase enzyme known as hexosaminidase A. It is inherited from a person's parents in an autosomal recessive manner. Three main approaches have been used to prevent or reduce the incidence of Tay–Sachs: Prenatal diagnosis. If both parents are identified as carriers, prenatal genetic testing can determine whether the fetus has inherited a defective gene copy from both parents.[30] Chorionic villus sampling (CVS), the most common form of prenatal diagnosis, can be performed between 10 and 14 weeks of gestation. Amniocentesis is usually performed at 15–18 weeks. These procedures have risks of miscarriage of 1% or less. Preimplantation genetic diagnosis. By retrieving the mother's eggs for in vitro fertilization, it is possible to test the embryo for the disorder prior to implantation. Healthy embryos are then selected and transferred into the mother's womb, while unhealthy embryos are discarded. In addition to Tay–Sachs disease, preimplantation genetic diagnosis has been used to prevent cystic fibrosis and sickle cell anemia among other genetic disorders. Mate selection. In Orthodox Jewish circles, the organization Dor Yeshorim carries out an anonymous screening program so that carriers for Tay–Sachs and other genetic disorders can avoid marrying each other. Each of the mechanisms above would work to eliminate embryos with two Tay-Sachs genes, and preimplantation genetic diagnoses could be used to eliminate embryos with one Tay-Sachs gene, though I have no reason to think it is used that way. By eliminating embryos with two Tay-Sachs genes, adults (who could reproduce) with Tay-Sachs are also eliminated and so I would think that over time, the genetic frequency of the Tay-Sachs disorder would decline. Is there any evidence of this for Tay-Sachs? Has the gene frequency of any recessive genetic disorder been reduced through screening mechanisms? submitted by /u/LJAkaar67 [link] [comments]

Does the electric field of light exert force on plasma particles? Posted: 18 Jul 2022 07:10 PM PDT Say there's a cloud of plasma floating in space, and there's a uniform magnetic field around/permeating it. If there is also an electric field present, the plasma will move in the direction of E x B, from what I understand. Now say there is a beam of laser light shooting through the plasma. Light is made of photons, which are electromagnetic oscillations. So how does a photon end up affecting the plasma? One option I could see is that the electric field from the laser and the background magnetic field means the plasma moves in the E_laser x B_background direction. Another option is that it moves in the E_laser x B_laser direction. Another option is that it doesn't move but oscillates back and forth along one of those directions, because light is oscillating. Another option is that it moves in the direction the light was going, because light has momentum and its pushing the plasma. Which is just the 2nd option, but with a different reason. Another option is that it doesn't move at all and I don't understand photons. submitted by /u/Bananawamajama [link] [comments]

If gravity increased drastically at a certain spot of the ocean, what would happen in that area? Posted: 18 Jul 2022 10:53 PM PDT Lets say for example there was a circle in the Pacific Ocean with a diameter of 100ft. Within that circle, the gravity increases by an incredible amount and it only increases within that circle. What would happen to the water in that area? would it cause a straight hole to the bottom of the ocean or would a different kind of phenomenon occur? submitted by /u/looking_at_themoon [link] [comments]

Do birds fly around for fun? Posted: 18 Jul 2022 06:01 PM PDT I've always wondered this. I'm on the 46th floor of a hotel right now and see small birds chasing each other around outside. Is there a biological reason for this (food / insects I can't see) or do they just fly around for fun? submitted by /u/nickofthenairup [link] [comments]

Where can I get a fasta file for the rhinovirus genome? Posted: 19 Jul 2022 10:45 AM PDT I'm trying to make a parser for .fa files and this seems like it won't be a huge file. submitted by /u/plsdontkillmee [link] [comments]

How is it possible for the JWST to have the bandwidth to send back all the data it's collecting? Posted: 18 Jul 2022 10:49 PM PDT It's so far away yet collecting so much data, I don't understand how it can send it all back. Is it using lossless compression of some kind? submitted by /u/non-troll_account [link] [comments]
