How significant is the genetic difference between the Northern and the Southern White Rhino?

Posted: 20 Mar 2018 03:19 AM PDT

With the last male Northern White Rhino dying today, and only two females left, chances for survival of the northern 'half' of this species is pretty much 0. Apperently they have enough sperm to keep the two remaining ladies getting pregnant, but it is not that straight forward of course.

To my surprise however, I read that there are thousands of their Southern counterparts left. I don't have a clue about the differences between the two though. Although the reasons they are still around might be really interesting, I am more interested in the biological difference between north and south. Could 'we' rejuvinate the northern species by using their southern brethren? How different are they?

Do current carrying wires also create electric fields or only magnetic fields?

Posted: 20 Mar 2018 05:41 AM PDT

My textbook is rather unclear about this. Much obliged for any answers :)!

  1. Does the net charge density change in a wire in a laboratory frame as current is applied to it?
  2. Will it become electro-statically charged?
  3. And does it therefore generate an electric field?
  4. Or are only magnetic fields generated following the Ampère's right-hand grip/corkscrew rule?

How did cells survive without a mitochondria?

Posted: 20 Mar 2018 02:24 AM PDT

There is a theory that the mitochondria was its own cell before being incorporated with another cell. If this theory is true how did the cells survive without a mitochondria?

Since humans are drilling so much oil out of the ground, are there large empty caverns underground where the oil used to be?

Posted: 19 Mar 2018 09:17 AM PDT

Humanity has drilled a lot of oil since the late 1800's. What happens to all the empty space where the oil used to be? Is it just empty air pockets now or does it fill in with dirt?

Does Quantum Field Theory rely upon one particular interpretation of quantum mechanics?

Posted: 19 Mar 2018 06:07 PM PDT

Is QFT an interpretation in and of itself? Is it contingent on one particular interpretation? Or can it be coupled with any interpretation, from many worlds to pilot waves to the Copenhagen?

How energy intensive it is to generate gamma rays for sterilization?

Posted: 19 Mar 2018 02:35 PM PDT

I have heard that one of the ways to very efficiently use and dispose of bio-solids, is to use them as fertilizers, problem is, you have to disinfect it, and using anti-biotics would be a horridly bad idea.

Could maybe gamma rays used to sterilize it for good? Would it be too cost intensive?

Why does the "bridge ice before road"?

Posted: 19 Mar 2018 05:00 PM PDT

Is this due to construction materials, elevation, what else possibly?

Where do volcanic gas clouds rise from?

Posted: 19 Mar 2018 03:12 PM PDT

Does the gas just leave through small cracks or is there so sort of hole at the top of every volcano? If the volcano never steams is that when it erupts? Why does it steam at all?

Is radioactivity a requirement for an element to be fissile?

Posted: 19 Mar 2018 08:08 PM PDT

I'm trying to understand some things about nuclear reactions. Radioactive elements fission spontaneously, whereas fissile elements can fission through the introduction of a low energy neutron. But are all fissile elements automatically radioactive? Is it possible for a large enough atom to fission easily without decaying on its own?

What happens when proton collides with an atom?

Posted: 19 Mar 2018 01:22 PM PDT

What happens to the energy of the proton? It is absorbed? If yes, fully or partially?

it's not necessary to explain. a few links that can clarify things would be good enough.

Does epigenetics have implications for horticultural/agricultural seeds?

Posted: 19 Mar 2018 06:17 PM PDT

I thinking of this as I was saving seeds from my heirloom tomato harvest - would seeds from a plant that faced drought produce a different offspring than one that didn't?

What about seed storage conditions?

Why do each booster from the Falcon Heavy cause 3 sonic booms?

Posted: 19 Mar 2018 02:12 PM PDT

My understanding of sonic booms are limited. After watching (are more specifically listening to) the falcon boosters landing, there was clearly 3 definitive booms per booster. My question is why are there 3?

Why where the alpha particles expected to pass straight through the plum pudding model?

Posted: 19 Mar 2018 04:01 PM PDT

Everytime I've heard about this experiment, right from grade 5 upto my analytical mechanics exam today, they say how the alpha particles were expected to pass straight through the foil but not all did. And then using Binet's equation and central potential we derive the neuclus model of the atom.

But absolutely no one has ever explained why can't the same be explained through plum pudding model? Even if electons were embedded into a positively charge pudding, one can derive the same central potential equations assuming atoms are rigid and nothing can pass through them; which they should be because it was called the "Plum pudding model" not the "Corn soup model"

Why is icing a 'sports' injury generally the first recommended go-to treatment and how does it promote healing?

Posted: 19 Mar 2018 11:20 AM PDT

As a lay person, rest and elevation make intuitive sense for a sprained ankle or whatnot, but icing seems weird. Like if you're not a professional athlete who needs to prioritize regaining mobility, why not let the injury swell, wouldn't an increased blood flow to the injury be helpful?
