Why can't HIV be treated with chemo therapy | I'm confused as to why you think it would be. The virus is still there. It would just attack the new T-cells. Chemotherapy specifically targets rapidly growing cells. Viruses are not cells and wouldn't be effected by a chemotherapy treatment. |
How do Transition glasses lenses work? | Ultraviolet light breaks a chemical bond in a special dye that coats the lens surface. Before UV exposure, the molecules in this dye are colourless. UV breaks a certain bond in the molecule, changing the structure, and resulting in a product that is coloured. When you go back indoors, away from UV, the reaction goes th... |
Why does English have different names for other country's cities? | Every language has different names for other country's cities. They are translated in the same way as you translate "dog" or "cat". Only the less known ones are kept in their original form. [Behold!] |
How are cameras able to follow who has the football in the NFL without fail, as well as when it flies through the air? | They have a lot of cameras all around and [above the field], run by professionals trained to see where the ball is.

Why are some people great at abstract thinking but terrible at algebra which involves it? | Math requires abstract thinking to understand why you're supposed to do certain things, but not to literally do them. You need abstract thinking to understand why you can divide two from both sides of 2x=4, but not to do it. The people that are good at math before calculus are people that can do well in a system that r... |
How does the Tor network protect anonymity? | Instead of connecting to a website directly, TOR creates a path with several proxies between you and the website you visit. A proxy is a computer that acts as a relay point. It asks the information for you then gives it to you. So let's say a path is built with only two proxies: Your computer < -- > Proxy A < -- > Prox... |
Is fire matter? If so, what elements/compoundss | what is matter? Never mind. What is mind? It doesn't matter.Interestingly, the difficulty in describing what a flame actually is sparked the Flame Challenge, a challenge to scientists to create a short video that could explain the concept to 10 year olds. He has since been continued on to answer other questions and is ... |
If i am in the US and shoot someone in Mexico and kill them who would have jurisdiction/what would happen | Mexico would request that the US extradite you to stand trial in Mexico. The US would probably complyI think this question could be better phrased as: "If I am standing at the US/Mexico border, on US soil, holding a gun, and I shoot it at someone standing on Mexican soil and kill them, who would have jurisdiction?" If ... |

Why do we have to close our eyes to go to sleep? | To turn this around, imagine *not* closing your eyes. They'd dry out and burn like crazy, be open to having random debris fly into them , and generally speaking the light would stimulate your brain even if you tried to sleep. Our brain helps us by closing our eyes for us when we're sleepy, forcing us to relax our eyes ... |
If the Earth's temperature is only increasing by a few degrees, why are massive chunks of ice breaking away in places that are always freezing cold? | **Average** temperature is increasing. This can mean, for example, that an area that had a day or two of above-freezing temperatures now has a couple of weeks of above freezing temperatures. |
Why aren't any of the nearest planets orbiting the sun on a vertical (as opposed to horizontal) orbit? | It's because the planets all formed from a disc of stuff that was orbiting the sun around its axis of rotation |
The Kansas-Nebraska Act of 1854 | This sounds suspiciously like homework, and there's a great and very readable wikipedia article on this subject. _URL_0_ |
How do those transparent EXIT signs read left-to-right even when you look at them from the other side? | Lol it’s simply a cutout of the word exit overlayed on top of a light usually red or green.

How can a biotech startup 3-D print fake rhino horns that carry the same genetic fingerprint as the actual horn? Is the printing at the DNA level? What material is used? | Keratin. That is the protein that rhino horns is made of. They make a powder of that and print that into a horn shape.Random question. Do Rhinos use their horns for anything?', "There isn't much detail in the articles online but one mentioned that DNA was originally isolated from a rhino and then amplified it ) so they... |
How can we be sure Quantum Superposition exists if it disappears when we measure it? | You can measure the effects of quantum superposition, even if you can't measure the superposition directly. A typical example of such an experiment is the double slit experiment where the particle is in superposition of moving through a left and right slit. Those different parts of the superposition then interfere with... |
Why can't Obama create an executive order to increase NASA funding as easily as Kennedy could in the 60's? | Congress alone has the authority to say how government revenue can be spent. Kennedy never raised NASA's spending on his own via EO. |

Why does looking at the sun always work when you need to sneeze but can't? | It's called a Photic Sneeze Reflex. Seems like about 10-35% of the population has it. It doesn't seem like anyone fully knows why, but people theorize that it has to do with a confusion of nerve pathways that are close to each other in the brain. Either way, it's pretty neat. |
Why can we see and hear whats in our mind? | Your brain takes inputs and processes them into "sensations" . When you remember something, your brain just reconstructs the "sensation" - so you see the image or hear the sound as you remember it. |
Why does my face squish up uncontrollably when I eat something sour? (Warheads, lookin' at you...) | I'm having a hard time finding the article I read on this a while ago but from what I can remember it had something to do with an involuntary movement that your body makes in an attempt to get ssaid warhead out of your mouth for you. Babies make the same face with a lot of vegetables because they don't like the taste s... |
Why do we say "pork," "beef," and "venison," for example, but "chicken," "lamb," "duck," etc... | That, to me, is one of the most fascinating quirks of English, and it comes down to the Norman invasion in the 1100s. When the Normans took over, they were the ruling class. Our food words are French in origin. They would tell their [English] servants to fetch some beef for dinner, or cook some pork. The servants, on t... |
Why are mosquitos able to successfully transmit certain viruses such as zika, malaria, and dengue, but not others such as HIV and hepatitis? | I can answer at least part of this. Mosquitoes aren't a viable host for HIV because they lack the T-helper cells HIV requires in order to reproduce. HIV breaks down in the mosquito's digestive system and never makes it into the insect's saliva, which is the only liquid a mosquito transmits into a human during its bite.... |
"People I may know" on Facebook. | Facebook doesn't just use *your* information for stuff like this. It also uses *other* people's information **about** you. So if one of your friends on Facebook has both your personal and work email addresses assigned to the same contact, Facebook knows that they belong to the same person, and associates your work emai... |
Why do people like Phish in such an extreme way? | I call it the 'fantasy of inclusion'. Same with diehard, over the top sports fans. Some people like being a part of something bigger than themselves, even if it's just pretend. If they like the band, or the team, or whatever, they try to make themselves a part of it. I don't think that every fan is living a fantasy, bu... |
- Why can't street signs, street lights, utility poles all be integrated to make a more pleasing aesthetic and eliminate clutter on American roads. | Lights need to be at a certain interval, power poles at another interval, and signs at specific locations. So it's not *always* possible to combine them. However, often they are uncombined simply because of a lack of coordination -- they are installed and operated by separate teams, working to separate plans, who'd rat... |
How can something exceed 2 Billion Kelvin? | Something can be really really hot, but not have enough energy to burn something When you use a grinder on metal and the little red sparks fly off, those are crazy hot but they're so small that if they hit your pants they don't have enough energy to burn them despite their high temperature If you bring 1 microgram of s... |
Why are there kid's shows on at midnight if they go to sleep closer to 8? | These are very helpful. I have two small children. Sometimes when we are traveling, or they are sick or it's a holiday or something, it is really nice to have children's shows available at strange hours. Also, my kids went to bed at like midnight when they were toddlers. What is important is the amount of sleep they ge... |
Why do certain sounds (like nails on a chalkboard) disturb people so much? | It is actually a trick on your mind A placebo if you will.They did an experiment once where they played people the sound of nails on a blackboard but did not tell them that the sound they were hearing was that.

In cartoons, why are moving items several shades lighter than the background? | This is typical of old-school animation that was done on cells. The background would be drawn once on one cell and anything that moves will be animated on a different cell. Since they aren't drawn on the same piece of cellulose the colors won't exactly match. |
What makes someone allergic to something, and how do those allergies cause reactions? | Allergies is a response to foreign proteins known as antigens and the body recognizes them and the immune system develops very specific molecules called antibodies to combat the antigens. So if there is not enough antibodies present, it causes the allergic reaction. The reaction is caused by disruption of mast cells wh... |
Why do movie tickets cost less during the day but other businesses don't change their prices during the day? | 1) Movie theaters make very little money from ticket sales, as a fixed percentage of those ticket sales go back to the movie distribution company. To you the price difference is $10 vs $5, but the theater only gets to keep a $1.50 vs $0.75. 2) Concession stand sales generate income for the movie theater, and those pric... |
How could physicists like Oppenheimer be brilliant in their field but bad at math? | I heard a mathematician say that being good at calculations is like being good at typing. You can be a great writer and still be a lousy typist, so you can be a good physicist and be bad at calculations. Plus, there is a lot to math outside arithmetic. Lost of math involves very few numbers. I assume you would simply a... |
is there a reason why 18 is the age where a person is considered an adult? Why 18 specifically? | It is a semi-arbitrary age. Some cultures say 16, some 14, it varies. Many use 16/18 because it is about the time you are pretty much fully grown, you can pretty much live without parental support, and not much more is happening that changes significantly after that, other then general maturing that comes with age/expe... |
Why can’t the USA government build a good website? | They don't need to. Companies build good websites because they want to draw in new customers and keep the existing ones. The government knows you don't have a choice. They also have a different set of priorities. They're concerned foremost with having the information & services you need, accessibility requirements & se... |
Why do we sometimes (especially when we're trying to sleep) start to dwell on past mistakes and blow them way out of proportion ? | When you are awake you are surrounded by other things you can / need to do. When you are falling asleep there are few things to distract you from whatever memory your brain presents. |
Why does science and creation contradict each other? | Science deals with things that are testable and falsifiable. Creation, as it is generally practiced, does not meet that criterion, in that faith is based on well faith. Therefore, there is not a condition in which intelligent design could necessarily be tested and proven false. It is thus not considered scientific. The... |
Why, as a child and into adulthood, is putting your finger in your mouth a natural reaction after you get a cut on it? | Saliva has minor anti-bacterial effects. Placing your finger in your mouth also cleans the wound and applies pressure to prevent further bleeding. It is similar to when a parent kisses a wound or an animal licking a wound. |
Is this experiment real or fake? | The battery generates electricity when it is connected back on itself via the copper wire touching the magnets. Electric current in loops creates a magnetic field - this is how an electromagnet is made. The magnetic field is only where the electricity is flowing, so only under the battery. This electromagnet repels the... |
Why is it I'm never hungry right after I wake up, in fact the thought of eating makes me feel sick, but than about an hour later I'm extremely hungry? | When you go to sleep, your metabolism shuts down as much as possible to save energy. No need to keep it running. When you wake up, it takes some time for it to realize you are awake and to start back up. That nausea feeling is derived from the fact that digesting food with a slowed down metabolism is difficult, so you ... |
Why are US troops being deployed to Poland? | Because Russia. Like it or not, NATO is primarily the Club of Countries the US Promises To Protect. Its ludicrously massive military is what everyone wants on their side. After Russia's adventures in the Crimea and Eastern Ukraine, there are suspicions within NATO that either Poland or the Baltics might suddenly find a... |
Why is confiscated ivory burned, and not auctioned off to legitimate artists/organizations/museums? | You're still allowing a market to exist when the product is there. By destroying the product, you know for a fact that it won't fall into wrong hands. Horrible analogy but I own a few sandwich shops. I don't let my employees take/eat mistake sandwiches. They have to toss them out because otherwise, mistakes magically s... |

Why do Police Departments still use the Crown Victoria when there are better cars available? | They're not better cars; for cops, at least. * don't have the room in the front seat for the necessary equipment * don't have the room in the back seat for perpetrators * don't have as easy a separation between front and back seats * don't have rear-wheel drive, so the front ends are more delicate WRT to obstacles and ... |
On Star Trek, how do they film people being transported, so that it looks like they literally vanished into thin air, sometimes even when there's motion all around them? | Lock up the camera so it doesn't move, film the people entering the transporter. Then they walk away. Leave the camera locked and then dissolve between the footage with people and without people. Add sparkly effects onto the film.If memory serves, the TOS effect was done by filming the transporter room with people walk... |
How does a full cycle charge extend a Lithium-ion batteries life? | It's not required for the battery at all. You know how the battery meter on your phone or whatever says 100% right when you take it off? And 57% sometime later? It needs to be calibrated to accurately determine from the battery what the state of charge is. Doing a full cycle occasionally helps your device do this calib... |
what does Gatorade do for your body? | Gatorade has electrolytes like sodium and carbohydrates in it to replenish electrolytes your body expends while working out. Other than that, it's really just sugar water. It doesn't have any magic properties that will make an athlete perform better. If you're trying to lose weight, you're better off just drinking regu... |
Why is petroleum used to make so many things? | Petroleum is a complex mix of hydrocarbon chemicals. It can be distilled to produce fuels, lubricants, solvents. Many of the chemicals we extract from petroleum can be used as "feedstock" for additional products: plastics, fertilizers, drugs.I'm overgeneralizing, but petroleum allows us to substitute naturally occurrin... |
When it comes to fallacies, is there any honest way to argue or debate without them? | Yes. Employ deductive reasoning and employ logic. Or use inductive reasoning and provide evidence to support a thesis. |
Why do playground slides always have so much static electricity? | Lots of rubbing means lots of electron shedding. When you shuffle your stocking clad feet on the carpet you get the same effect. Now imagine hundreds of pairs of pants passing over the slide.People's clothes sliding on the plastic, so basically certain materials become electrically charged after they come into contact ... |
Why are Anime characters drawn with such large overly exaggerated eyes instead of eyes that are more characteristic of normal Asian eyes? | From [_URL_0_]: > Anime characters having large eyes is generally attributed to Osamu Tezuka{1}, an artist prolific enough to be called the "father of manga", and the creator of Astro Boy, the source of the image you shared in your question . > At the time of Astro Boy , Tezuka was inspired by precursors in animation, ... |
Why do you have to have an account at a bank to make change? | It's usually free to open an account, and usually free to close one. Once you ask them to get the forms, they'll generally make change for you anyway. Also, if you need a phone charger, go into a hotel and say you left one in your room when you checked out. They always have a huge box of left-behind chargers back there... |
Why are men's shirt buttons on the right and women's on the left? | Not at all. But women did not dress themselves. Or at least noble ladies didn't. They had servants for that. So the buttons being on the other side makes it easier for the servants to work. Men would dress themselves. So their buttons would be on the right. |
Why do people say the size difference between countries means economic policies won't or will work less efficiently? | The size argument is fairly weak. Scaling can be achieved. A large country could save more money by being efficient compared to a small country. A better argument against using small countries as models is the diversity of large countries. Rules promulgated for a large country may just not work in Alaska, New Mexico, e... |
What is the difference between a good lawyer and the "best lawyers money can get you" while defending you in a case? | To put it simply as thus: A good lawyer works within the law to get you the best result possible. They work with the system, and don't break the rules, and so are good all round. The best lawyer money can buy, however, is one who knows when, where, and how the rules can be bent. They know how far the rules can be bent,... |
Why is it there isn't a large British population in Hong Kong if it was a British colony? | Only a very small percentage of Hong Kong's population is white according to recent census records. Not every British controlled territory was a settler colony. Hong Kong was taken from China mostly to be used as a port of entry for British businesses to sell things to Chinese people. They didn't take it with the inten... |
Differences between UK and US student loan systems? | The first part is pretty much the same here. If you're going to an expensive college then you're going to end up with a lot of debt. In the US, the threshold for garnishment is pretty low. If you take home more than 30x the hourly minimum wage , they are going to take a portion of it. As far as not paying it back at al... |
Is it possible to create a nuclear blast with a blast radius under 10m? | No, it's not. As an example, the Davy Crockett was one of the smallest nuclear weapons ever built. It was a tiny nuclear warhead meant to be fired from a tripod-mounted recoilless rifle; basically a small cannon with a nuclear payload that a few dudes could carry in pieces or a vehicle could carry easily. Kind of a coo... |
What exactly makes cracking your knuckles bad for you? | Nothing. No study has found any causative link between cracking your knuckles and degeneration or harm in later lifeFor 60 years, a Californian doctor cracked the knuckles on his left hand frequently, but never on his right hand. In 2009 he presented his findings, showing no signs of arthritis in either hand, and was a... |
if evolution weeds out undesirable traits in a species, shouldn't everyone in the human race be a 10 in hottness? | Evolution doesn't care how hot you are; it cares how well you reproduce. Nothing else.Evolution does not weed out anything, nor does it have a goal. Evolution means "good enough to reproduce"It only weeds out things that don't reproduce. Things don't reproduce for various reasons like it dies or can't get a mate. You w... |
How will Mars colonists deal with radiation and deadly sun rays? | We're nowhere near the level of Technology needed to combat solar radiation on Mars. The best we can do so far is to put a lot of mass in between our body and the Sun. This just means pulling a big pile of dirt or water on top of our shelters AKA living underground or underwater |
Why do "bags" under peoples eyes appear? | It's very thin skin so edema and water retention are more obviously visible there. Can be caused by allergies or electrolyte imbalance and probably lots of stuff.Another question, how to get rid of it???', "Why do you not use the search function? Submission guidelines: * Search before submitting! If it's been asked bef... |
Why do Scottish Fold cats have those weird, sausage-shaped tails? | The same reason pugs have smashed faces. A breeder sees one of their kittens has an oddly shaped tail, decides they like that trait and breeds it with another cat that has an oddly shaped tail,and its offspring has a more distinct oddly shaped tail. |
Why can spiders hang upside down for long stretches of time? When if we did that the blood would rush to our head and cause us pain. | Because invertebrates like arachnids and insects don't have a closed circulatory system with blood like we do. They are essentially hollow exoskeletons filled with fluid. Their "blood" is already everywhere it can be so there is no sense of it rushing to one part of their body or anotherI could mention that Spiders don... |
How differential equations are used in real life? | One of the simplest is modelling population. If we understand how a population changes we can create a differential equation that we can hopefully solve to get a population equation. Rocketry & Hydrodynamics have differential equations. Recently the Black-Scholes equation was created for finance. Differential equations... |
Why does powdered sugar taste so different from regular sugar? If they are chemically/molecularly the same, shouldn't they taste the same? | Powder Sugar has small a amount of cornstarch in it. Why it tastes different. Well steak in a blender tastes different than steak on a plate.I'm no sensory expert, but have a bit of experience in the food industry. First, powdered sugar likely isn't chemically identical. They use anti-caking ingredients to keep it free... |
If corporations are considered Legal Persons, and legal persons are required to pay income tax, why aren't profitable corporations like Merck, GE, and Verizon paying any income tax? | Business expenses are tax deductible. When you're a business, every expense is a business expense so you only pay tax on profits, not income. By careful bookkeeping and passing money between subsidiaries, the corporate accountants can make it look like the company didn't make any money so they don't owe any taxes.They ... |
Why do dogs tilt their head when confused? | I am by no means an expert on this, but from what I remember of a documentary that explained this, dogs read human facial expressions, specifically on the left side of your face. If a dog is confused, it may try to read your face to pick up cues on how to react to the confusing thing, the head tilt resulting from focus... |
Why do teenagers get more acne than adults or children? | More hormones = chemical imbalances in the body making the greasy stuff on your face. As you grow older it balances out I guess and acne reduces? Some adults have it though. |
How to do Internet/social media marketing | I would say start by reading what other companies you love have done - one of my favorite companies is Intercom - they have a book called “lessons learned” which talks a lot about reaching customers and connecting with them. - they also have a book specifically on marketing. Also, they are incredible at reaching people... |
Why does some ocean waters seem so crystal clear and others aren't as blue? | If you notice the areas with clear waters, they are tropical and are usually on the east coast of a continent. That's actually because the way water flows around the equator stacks up warm oceanic water along the east coast of continents. Along the west coast, and at more extreme latitudes, the water is coming from the... |
Why are radio stations only odd numbers? | Due to FCC rules in the US to ensure that radio stations don't interfere with each other and distort sound [source] |
Why does an egg become solid with heat when other things usually become liquid with heat? | Please search, this question is asked a lot. [This is the best explanation so far , and search can lead you right to it]. Eggs are not filled with a simple molecule like water or alcohol. It's a very complex protein structure that changes chemical properties when heated. That's why cooking an egg can't be "undone". |
How can you "feel" it when someone is staring at you? | You can't. Studies have been made to test it, and it turns out that the feeling of being watched is not linked to actually being watched. You just remember the times that you got the feeling of being watched and it turned out that you were actually being watched. Confirmation bias.I do think there is something to be sa... |
Can I get sick if I do a poo in a public toilet and splash goes straight up into my open date? | Your bumhole doesn't open up completely. Poo gets squeezed out, it doesnt fall out. If some water does splash up it doesn't go into your bumhole, it stays on the outside. I'm going to do some experiments and I'll let you know exactly what happens. |
Is the act of overeating in itself bad? | Gaining weight is just one unhealthy aspect you can develop from overeating. You can have poor health and still be skinny from a bad diet.There's differing medical advice on whether eating one or two large meals is worse for your health than eating many smaller ones - there's plenty of research that leans both ways or ... |
On a sunny day, why does it look like there's water on the street from far away, but when I get there it's dry? | It's a mirage, just like in the desert! The hot air refracts light at a different angle than cold air, and pavement gets real hot. So, you are seeing reflected light right above the hot pavement which shimmers like a puddle. |
Why do animals prefer belly rubs, while humans prefer back rubs? | Belly rubs are not more preferred. A dog or cat or whatever is acknowledging you are their superior. "Guess I gotta show my belly, \'cause that human feeds me and is my master." But to the anthropormorphic minds of a human, "Ooh, they like that better, isn't that the cuuuutest yeah, belly rub is good isn't it, boy?" Be... |
Upon reading about Sandra Bland, I have to ask: What civil rights do I have as a citizen when a cop pulls me over? (ex. cigarette) | You have the right to free speech. You have the right to be secure in your person and papers. You have the right to remain silent. These are given by the first, fourth, and fifth amendments to the constitution. In actuality you have a lot of rights beyond that, but it is going to depend on the jurisdiction you get pull... |
Why do politicians these days seem so corrupt!? Have they always been this way? | They're probably less corrupt then they were 100 years ago. But with the constant media exposure and nonstop TV analisys, we see even relatively small conflicts of interest as huge discrepencies. |
Why don't I cough when I sleep? | I very much so cough in my sleep. So does my dad, and my mother, and often he has come to wake me up to give me medicine so I'll stop making so much noise. Record yourself while sick if you want proof. My roommate also coughs while sick and asleep. I also woke him up and forced medicine on him so I could get to sleep. ... |
In scientific theory, why do we need to hypothesize? Why can't we just go "Let's try this and see what happens!" | In reality there is no difference between hypothesizing and what you have described. In modern science you only publish hypotheses that turn out to be correct, and so you essentially play around, do this or that, whatever your intuition or other studies suggest might be a useful thing to do until you find something int... |
if and when all the sea ice melts will it change the salt levels in sea water. | There's a LOT of fresh sea and glacial ice, enough that if it were all to melt sea level would rise by 70 meters . So yes, the salt levels in the oceans would drop noticeably and probably enough to significantly alter ocean currents and change weather patterns across the planet. |
why radon is considered as a great health problem in temporal countries than in tropical countries? | Houses in tropical zones don't often have basements and are often traditionally based on pier/piling foundations and raised floors. Without basements to trap it, radon from the ground dissipates in the air. |
Are Quantum fluctuations truly random (non-deterministic) or do we not yet possess the capacity to understand the perceived randomness of such fluctuations? | You want to look into [Bell's theorem]. Bell proved with some fairly basic assumptions that some physical property of particles, that we are just unable to measure thus far, cannot explain the experimental results. The details of the experiment and the argument are explained in [this askscience] thread in a fairly laym... |
Why is gas so much more expensive than it was in the 90's? | So has demand. So many more petroleum products are in use now, as well as cars on the road in the worldA few reaons: Increased demand: People in poorer countries, like China or India, are buying more oil now than ever. This causes the price to rise. Cheap oil is running out: Companies, obviously, prefer to mine the che... |
Why does everybody from past generations, male and female, look much older than somebody from today with the same age? | People weren't informed about the dangers of smoking, alcohol, and the sun.* poor nutrition* poor hygiene* less advanced medical care, and less care in general* more hazardous working conditions* more time spend out in the sun* having more children earlier* less disposable income to spend on grooming and cosmeticsThe s... |
How do cities remain modern looking as time passes? | Because things build up around the old portions of the city, so that the older, small parts are less noticible in a larger overview of the city. If you explore a city locally, you'll find the older portions, but the sky line will be dominated by all the new things. |
What exactly is happening in my brain when I can hear music/sounds coming through into my dreams? | Everything that your senses are perceiving is going to be accessible to your brain, they don't turn off.
