What happens to microbes' corpses after they die?

Posted: 12 May 2019 04:03 AM PDT

In the macroscopic world, things decay as they're eaten by microbes.

How does this process work in the microscopic world? Say I use hand sanitiser and kill millions of germs on my hands. What happens to their corpses? Are there smaller microbes that eat those dead bodies? And if so, what happens when those microbes die? At what level do things stop decaying? And at that point, are raw materials such as proteins left lying around, or do they get re-distributed through other means?

If including risk-taking and substance abuse, how do the genders compare in deliberate self-harm?

Posted: 12 May 2019 07:05 AM PDT

Studies find that male suicide rates are far higher than women's, across regions and countries. However, it seems that delibarate self-harm (DSH) is more prevalent in women throughout Europe, with Finland as a possible exception. But what is the case if one includes deliberate risk-taking activity—such as choosing the most dangerous jobs, performing dangerous stunts in front of friends, or consciously picking fights—or using substances (alcohol, drugs) in order to punish oneself? These kinds of activities are generally associated with men, so it would seem that perhaps DSH numbers might look different if such problematic actions are taken account of as well.

What causes some coastal cliffs to have thin beaches at their bases, while others have deep or rocky water immediately?

How were the most recently discovered Elements (ie. 113, 117, 119 ect.) documented, when their half lives are so short?

Democracy will inevitably help majorities at the expense of minorities because majorities will vote with self interest. Is there a known governmental system where decisions are made with more equality?

Calculating the trigonometric functions, logarithms and square roots by hand. How?

Posted: 12 May 2019 02:19 AM PDT

Is there a method of calculating sine, cosine and other trigonometric functions by hand? Here I am not talking about the angles we know the trig functions of by heart, but of an arbitrary angle (68.4 degrees for example). Logarithms and square roots as well. Moreover, how did people do it before the times of computers and calculators? I have found that Taylor series can be used, but the first term still involves calculating the value of the function. If not Taylor series, then how?

Why do some exhaust fumes from airplanes stay in the sky for hours (the white long lines), while other disintegrate and disappear immediately?

Why is the membrane of a cell called the "plasma membrane" when it's made out of lipids?

Posted: 11 May 2019 02:50 PM PDT

According to my understanding, plasma is another state of matter (the fourth secret one you don't learn until around high school), and is a large part of your blood. So, in the context of the lipid bi-layer for all animal cells, wouldn't it make more sense to call it the lipid membrane? Thanks for your answers

How does a diet of an ancient people compare to an average modern diet?

Do our eyes adjust to motion like they do to light?

Posted: 11 May 2019 01:54 PM PDT

For example, when I'm playing a game at 30 fps, it will initially feel slow and laggy, but after a bit, it looks like it's moving smoothly, even though the framerate hasn't changed. After I stop playing, real life will appear to be moving faster and smoother, but after it bit, it becomes normal again.

So I'd like to know: do our eyes (or maybe the vision center of our brains) "slow down" or "speed up" with the speed of what we're observing, like how they let more or less light in depending on the amount of light we're looking at?

Is there anyway to heal a smoker's lung? Or has the damage been done already and requires a transplant?

How are they considered new elements when half lives are so short?

Posted: 11 May 2019 03:21 PM PDT

I am aware of the band of stability and what it means, and with the recent discovery of element 118 Og we now completed row 7 of the table.

What I dont understand is how are these new elements considered and confirmed as new elements if they only have half lives less than a few seconds Og being less than a few milliseconds, so how is it technically classified as an element if it isnt even stable?

Is it possible for there to be Earth bacteria now living on Mars because of the rovers we sent there?

Posted: 11 May 2019 08:57 PM PDT

A bit of a shower thought I had recently: Is it viable that humans have inadvertently colonized Mars with Earth bacteria that had attached themselves to the Mars rovers? Would it have all died on transit? If it did survive, is it a possibility that it could reproduce and thrive on the surface of Mars?

Thanks in advance.

What does cancer-free actually mean?

Posted: 11 May 2019 11:58 PM PDT

Does it mean there is not a single cancerous cell in your body?, Or is it like on probability basis, that you have a high chance of not getting cancer again?

What actually increases risk of lung cancer when smoking?

Posted: 11 May 2019 03:03 PM PDT

I may get this completely wrong but my first guess is increased risk of denaturing your cells DNA due to the smoke, heat, chemicals, etc.

How can we know one proton moves atp synthase ‘turbine’ one measure without being able to see the protein, let alone the specific mechanisms?

Posted: 11 May 2019 08:58 PM PDT

Is the turbine model just a theory?

Theres some interesting visuals on YouTube I would have never questioned, and multiple sources collaborate so it must be true, but my father posed the question and I was at a loss.
