How realistic is the cancer "vaccine" talked about recently? Posted: 01 Feb 2018 12:36 AM PST A recent post to /r/worldnews is talking about a cancer "vaccine" talked about in this article. All sorts of claims have been made about cancer in the post. So, how realistic is this? submitted by /u/SomeCoolBloke [link] [comments]

For GW150914, the first observation of gravitational waves, the stretch was miniscule upon reaching Earth. What would the stretch have felt like closer (ex. 1 light-year away) from the event? Posted: 31 Jan 2018 03:26 PM PST Would it have been a similarly small amount, or would the energy have decayed far less at that point? Is there an amount we could calculate for the stretch? The stretch on Earth has been described as follows: "For example, the waves given off by the cataclysmic final merger of GW150914 reached Earth after travelling over a billion light-years, as a ripple in spacetime that changed the length of a 4-km LIGO arm by a ten thousandth of the width of a proton, proportionally equivalent to changing the distance to the nearest star outside the Solar System by one hair's width." submitted by /u/Schamson [link] [comments]

Do larger stars have more planets in their Goldilocks zone? Posted: 01 Feb 2018 06:29 AM PST Some stars are enormously bigger than Sol. Would they have a larger Goldilocks zone where we might find life-supporting planets? submitted by /u/photolouis [link] [comments]

Would the cross sectional shape of a wire (circular, square, or even star) make a big impact on how electricity flowed through it? Posted: 31 Jan 2018 06:50 PM PST I read that most of the current flows near the surface of a wire due to eddy currents and the skin effect. What would happen if you changed the shape of the wire? submitted by /u/madethisforoneremark [link] [comments]

If human cells can repair themselves, why is radiation cumulative over a lifetime? Posted: 31 Jan 2018 10:14 PM PST I am aware that the radiation experienced by humans (background radiation, x rays, CT scans, etc) is cumulative over a person's lifetime, and harmful because it can alter the construction of cells in the body. Yet, at the same time, human cells are able to repair themselves rather quickly. Given the the fact that radiation alters cells but they are constantly being repaired by the body, why is radiation exposure cumulative over one's life? submitted by /u/dylan1200 [link] [comments]

How were microprocessors made before automated robots (which use microprocessors) were invented? Posted: 31 Jan 2018 07:09 PM PST This seems like a paradox - since microprocessors require a level of precision beyond what is humanly possible, we use computers to do the precise work. How were the processors made before those computers were even invented? submitted by /u/saucenpops [link] [comments]

Do we share diseases with dogs or other domesticated animals? Posted: 31 Jan 2018 09:34 PM PST We have been hanging around with dogs for over 10,000 years. Have any diseases been able to jump the species gap in that time? submitted by /u/Luke-Is-Cooler [link] [comments]

If dogs and cats use urine to mark their territory, do individual animals have unique-smelling urine? How do dogs and cats produce this unique scented urine? Posted: 31 Jan 2018 07:47 PM PST If dogs (and cats) pee to mark their territory, I infer that different dogs will recognise their own urine and, therefore, that dogs have uniquely-scented pee. Is this true? Assuming that it is, how do animals produce these scents, and when (or where) in the lifetime of urine, is the urine laced with the scented-substance? submitted by /u/CortillionTheDancer [link] [comments]

How are sharks “immune” to cancer? Posted: 01 Feb 2018 04:28 AM PST I know they aren't fully immune but can we use them as research create better medicine in the future? submitted by /u/Assinmik [link] [comments]

How do engines of different numbers of cylinders but the same displacement per cylinder (bore X stroke) compare? Posted: 31 Jan 2018 06:58 PM PST It seems that more and more cars have .5L per cylinder and it got me to wondering- Now, I know that most of the time V8>V6>I4 but I'm hoping for a more specific answer than bigger engines = moar power. If you had a naturally aspirated engine that had cylinders with a bore of 89mm and pistons with a stroke of 80 as: a 2.0L I4, a 3.0L V6 and a 4.0L V8- assuming all other relevant factors are identical, how would the power output and delivery differ between the engines? Would the V6 have ~50% more power than the I4? Would the V8 have ~33% more than the V6 and double that of the I4? How would the losses due to internal friction vary by engine and affect that engine's output? Would they all see similar power curves and redlines to each other or would they be similar to other I4/V6/V8 engines? I appreciate any answers and please be gentle, I'm just trying to learn! submitted by /u/howdyfrickindo [link] [comments]

Why does ice on distant asteroids and planets remain solid instead of sublimating into a gas? Posted: 30 Jan 2018 07:06 PM PST The New Horizons probe showed us ice plains on Pluto, and we know that asteroids also contain ice. I understand that these places are very cold, but they still receive some light from the sun.

Understanding the birds in a box question (no weight change), what if the box was moving through the air and the birds were gliding? Posted: 30 Jan 2018 07:55 PM PST If the 'box' was open ended, and the box was either moving through the air or air was being pumped through it at a rate that made the birds glide under no power, would the weight of the box change? I've been talking to people about this for a bit now, and ground effect, closed vs open system are making this tougher to reason than I thought. Any advice is appreciated. submitted by /u/KarockGrok [link] [comments]

Why does adding baking soda to a reduction of water and red cabbage cause the liquid to turn blue? Posted: 30 Jan 2018 08:32 PM PST Hey askscience, I am making some food coloring at home, and the recipe called for boiling red cabbage in water, then separating the liquid and adding baking soda until it reaches the desired blue color. My question is, in terms of the chemistry, why does this happen? What causes the cabbage/water solution to go from a deep reddish-purple to blue? Thanks! submitted by /u/Nickodious [link] [comments]

Is donated blood cleared of hormones? Posted: 30 Jan 2018 05:44 PM PST So when a man gives blood, is there testosterone in his blood that is passed on to the recipient? Same for female hormones. Could someone who needs regular transfusions like a cancer or hemophilia patient end up manifesting second sex characteristics of the other sex based on the hormones in the blood they receive? It would have to be a lot, and very often, though, right? submitted by /u/Blerkler [link] [comments]

in quantum mechanics Is it possible for a piece of matter to disappear and reappear in a different position instantly? Posted: 31 Jan 2018 02:06 AM PST I was having a discussion with a friend the other day about quantum mechanics and he was lead to believe that you can physically observe a piece of matter in the universe, specifically a space ship disappear and reappear somewhere else using the quantum theory. (i'm a novice on this subject) I think I understand that quantum mechanics states that an object can be in multiple places at the same time but when we observe the said object it only appear in one place. So is it possible for an object to be observed disappearing and reappearing in a different place? submitted by /u/DividedQuantum [link] [comments]

Why does helium make voice higher pitched if source frequency remains the same? Posted: 29 Jan 2018 07:15 PM PST I know sound moves faster in helium, but I don't see why frequency should be any different if the source vibration is the same as it is in air. (eg). Say in air, sound speed is R m/s, and there is a vibration at 1 Hz. Vibration starts at t=0. Vibration just started, so distance moved is 0 meters. After 1 second, t= 1, so vibration has moved R(1) = R meters. When t=1, second vibration starts. This distance traveled is 0. Well, because both vibrations move at the same speed, the distance between the first and second vibrations (and 3rd, 4th, etc) is always R meters. And since vibration travels at R m/s, there is a 1 second gap at the receiving end between each vibration. So how does sound speed affect frequency? submitted by /u/yosimba2000 [link] [comments]

Why doesn't aluminium fuse directly to copper? What determines the kinds of metals that can be fused or amalgamated among each other? Posted: 29 Jan 2018 05:53 PM PST Hey there kind scholars! My girlfriend and I have a strange habit of watching old episodes of that Discovery channel show, "How it's made", to relax and sleep. Last night we watched one episode on "Thermal machines" (such as air conditioning units and refrigerators). On a certain moment during the fabrication of the air conditioner, the narrator said that a certain piece of the aluminium "net" component had to be welded to copper using a zinc-aluminium alloy. The question(s) then is (are): Why can't the copper and aluminium be welded directly? What characteristic on a metal determines it to be able to be welded or amalgamated to another? Edit 1: a comma. submitted by /u/lewdlou [link] [comments]

How are raw alpha particles and electrons collected for use in experiments? Posted: 29 Jan 2018 10:26 PM PST In a physics class, our class discussed famous experiments such as Rutherford's Scattering experiment, in which alpha particles were sent into gold foil, deflecting off.

How do we solve problems that don't have constant acceleration? Posted: 29 Jan 2018 10:58 AM PST I understand basic physics and how we solve motion problems using kinematic equations, but these all rely on a constant acceleration.

[rocket engineering] Ice as rocket fuel ? Posted: 30 Jan 2018 02:06 AM PST So, my knowledge of rocket science is basically on the level of "avid Kerbal Space Program player". I understand concepts like Delta-V and TWR. So onto my question. As ice defrosts it becomes liquid and then gas. Now water is a bit of a problem here since it actually gets less dense as a solid, but most things it's the other way around. So picture a tank full of some frozen substance, with a nozzle on the end. As it defrosts and evaporates it builds up pressure, expelling some of the gas out the nozzle - and you have a rocket engine. Since space is cold, you may want to use an electric heater to get it going - much like Ion engines are driven by electricity though I know that electric heating is rather more energy hungry. Of course if the substance in question has an evaporation point above the average temperature of space (to the extent that "temperature" makes sense in a near vaccuum) you may not even need that (at least, closer to the sun). Would such a rocket be viable at all ? How would it compare to say - a xenon Ion engine like we already use ? What substances would make the best candidates for an ice fuel in terms of ISP, delta-V for the weight, energy required to melt it and viability of working with the substance ? Frozen CO2 [dry ice] has been proposed as a generator-driver for Martian colonies - would it be a good candidate ? I'm under no illusions that I've stumbled onto a rocket design that the best engineers at NASA and SpaceX have somehow overlooked - I'm just curious about how the idea would work in practise as a hypothetical and what sort of difficulties you could expect ? I see no viability at all for lifting rockets - so think in terms of vaccuum engines to use to accelerate your probe on it's way after you are already in space (much like Ion engines are used). submitted by /u/metalpoetza [link] [comments]

What's the current state of research for nuclear power regarding efficiency and nuclear waste production? Posted: 29 Jan 2018 05:21 PM PST (heads up: I'm not very well familiar with advanced chemistry and physics, so I am looking for more of a layman's explanation!) I live in Germany, where nuclear power is commonly not considered clean energy. This is mostly due to the extremly longliving toxic waste it produces. Therefor we have big political movements in Germany pushing for shutting down the nuclear power production all together. Thus (as far as I know) there hasn't been that much modernization going on over the past few decades. A few years ago I read somewhere that nuclear power production today is far below it's potential and that modern scientific research is quite promising regarding the effiency (I think it said that were at ~10% of the potential effiency due to our lack of modernization) and waste production (I remember something about ways to reduce the radioactive waste to minimum of what is currently done). I also remember reading something about ways to recycle spent fuel to bascially use it up until it's gone and power plants that are basically failsafe. Sadly I have no idea where I read this and I don't remember it looking very 'scientific' (iirc it was one of these pseudo-scientific looking inforgraphics). So I was wondering if you could tell me what acutally would be possible if mankind was to decide to heavily invest in modernizing nuclear power production and what could be expected from further research. Are there known ways to get rid of dangerous radioactive waste? Or is this just the propaganda of the nuclear lobby, trying to convince people that renewable energy sources are not the absolutly best option for the future? submitted by /u/uberjack [link] [comments]

How exactly does the immune system ward off external parasites? Posted: 29 Jan 2018 12:57 PM PST My curiosity was piqued by reading about mange in dogs, specifically quotes from this page about how a healthy immune system keeps mites under control: Demodectic mange most often occurs when a dog has an immature immune system, allowing the number of skin mites to increase rapidly. Source: https://vcahospitals.com/know-your-pet/mange-demodectic-in-dogs Since mites are outside of the body and presumably too large for white blood cells or the typical immune system defense against e.g. bacteria anyway, by what mechanism exactly would it be affecting their reproduction? submitted by /u/unthused [link] [comments]
