How do our bodies break down over time? | There are sequences of DNA at either 'end' of genes called telomeres. These telomeres protect the genes from degradation. Copying errors tend to occur at the ends of genes, so the telomeres 'take the hit'. Because of this they get shorter and shorter the older we get. So the genes start getting damaged themselves. This... |
What are the usual “Natural Flavors/Colors” in foods, and why are companies getting away with using these vague descriptions? | A natural flavor or coloring is sourced from a mineral, a plant or animal.

Why did "haggling" the price of a car become so commonplace, when nearly everything else a person wants to purchase is typically "It costs what it costs"? | A few reasons: * Most retail locations use hourly employees who both don't receive bonuses for how much profit is made from selling things, and who typically don't have much authority to actually do anything about the prices. I can't take a loaf of bread to my supermarket's checkout and haggle the price because the cas... |
How do scientists create materials with specific properties outside of random chance? | It's a pretty broad question but as a broad answer, it's more making educated guesses than it is just guessing.

When mouthwash says it kills 99% of germs, is that not just breeding super-bacteria in your mouth? | Stuff like alcohol, peroxide, bleach etc. is basically chemical fire. Only way to not die to it is to not touch it. Can't develop resistance to it. & #x200B; Antibiotics are like Street Fighter combos. It'll kill stuff that doesn't know how to block it, but sometimes there are a few individual bacteria in a population ... |
Fur on coat hoods? | The ruff disrupts the wind. It makes a huge difference. Surprisingly, the type of ruff fur also makes a big difference, with natural fur being vastly superior to synthetic.

Why does horseradish burn your sinuses? Like why your sinuses and nothing else, and why does the feeling shoot up your sinuses like that? | Slightly unrelated, but I think it's funny how when I was growing up no one would let me eat horseradish because they didn't like it and hence wouldn't let me try it, but once I tried it I loved it! So much better than chili peppers or that kind of spice! |
What is the physiological difference between (cannabis induced)munchies and "real" hunger? | As others mentioned, munchies = increased appetite. Hunger is just that, hunger.

So cannabis can increase their appetite. Another thin... |
why do sheets feel cold when you first get into bed, but then warm up, while blankets made if wool or other fuzzy-type materials are immediately warm? | Heat transfer. Some materials transfer heat energy more easily than others. Things that transfer heat easily , feel cold to the touch at room temperature because they are pulling heat out of your body very quickly. Once the sheet is warmed up to your body temperature, it can no longer transfer any heat from your body, ... |
If a person has a skin graft with a mole or skin tag, does it die after being moved? | I wouldn't believe that it would die because a skin graft gets nutrients from blood vessels despite not having a blood supply. |
How do motor boat engines not get water logged? | On large sailboats with internal motors there is a thing called a stuffing box.

How can light be a particle, if when a beam of white light hits a crystal and splits there is more “beams” of light. | Firstly, we would consider light as a wave in the situation you're describing. However, keep in mind that white light is just a combination of light of every colour. White light is not one single photon, but many many photons of different energies . The crystals simple separates out the colours. |
We put ice on an injury to stop it from swelling. Why is swelling bad? And if it’s so bad, why do injuries swell up? | Swelling partially immobilizes nearby joints to prevent further injury, and sending heat and blood to the location of an injury helps accelerate the cleanup and repair process. Cell movement and chemistry works faster at higher temperatures - to a point. This process isn't super well controlled though, and the inflamma... |
How were there surrenders in such large numbers during WW2? | I don't know if you realize it, but the Soviets had 6,400,000 troops marching towards Berlin. SIX MILLION! The Germans only had 1.9 million troops left to defend. On the other side, the Allies had 4,500,000 troops marching towards Berlin. Those same 1.9 million guys had to defend against them also!

If so then no, they're hallucinations induced by flooding your serotonin receptors. Hallucinations, by definition, are products of your own imagination. |
Why are glasses always drier than plastic cups after the dishwasher's done? | It's got nothing to do with heat retention or thermal mass, as the other comments would suggest. It's the water attracting properties of the different surfaces. Glass and ceramic are attractive to water, so the water spreads out in a thin sheet, then evaporates faster. Plastic is repellent to water, so any water on it ... |
