Skeletal muscles undergo the Cori Cycle, but this is impossible for the heart. So during Angina, how does the heart cope with Lactic Acid?

I understand that it will eventually burn out. But why does the very heat it gives off not melt the source of the heat?
Anything on earth will melt if it gets hot enough, why not the sun, it's nucleus.
There is something I am missing here.
Is it, in fact, melting but is just so large that it will take billions of years to melt the core completely?
Thanks.

I believe so but i want more evidence. i saw a show on discovery channel that said the plants in the circles are not flattened, they're heat treated and thats what makes them lay down. they concluded this by lab analysis of the plants which showed changes in the plant that only heat can make. im' serious if u have any info or learned something about it, please put down what u learned.

I've been working in a biology lab over the summer, and at the end of the program we have to give a poster of our work (with the abstract due less than a week from now). But I've only been here about six weeks, so obviously I don't have any significant data to present (I've been working with a postdoc on his project that will take a couple years to complete), and I haven't been able to get anyone to give me any advice on what I should actually write about (and yes, I have asked). I've written plenty of abstracts for lab reports and stuff, but the main point there is always the major conclusion of the paper, so I'm not sure where to even start for this one. Any suggestions?

I've noticed sometimes when I drive down the street, as I pass under street lights they go out. I've never seen a street lamp go out from far away. Only as I drive past it. The same lights are working again the next night, so I assume they come back on at some point, but I find it strange that they go out as I am passing directly underneath. It happens all the time. I've noticed it happens when I'm driving and thinking heavily about something. Does this happen to you?

I've asked this 4 times with no help so help me find the equation of a parabola with the vertex at the origin with the focus on the y axis. There is a line with slope 1/2 going through the focus. Find the value of the focus (or length of P if you prefer) and then find the equation. Explain please and help me on this or I will die trying to figure this out.

other similar questions:

1) what is the farthest point from any continental land
2) what point of land is farthest from any point of seawater
3) considering currents and winds, what point of the ocean's surface would cause you to be stranded on a raft for the longest time (i.e. from this point, it would take the longest time to drift to land)

Can a rocket produce more thrust when it is in the air because it has air molecules to push against? Can the presence of air molecules cause more pressure to build up inside the thrust director and thus increase the amount of thrust per fuel burned? Do any physics buffs have input on this question?

Like time is sweeping over the planet in a continual calculatable band of 'current local time' (example in New York city it's 4:20 but in LA it's 1:20, so in increments larger than a few miles but smaller than waiting until the next date line it's 4:20 east of New York in a band of current local time moving toward LA.) So instead of there being time zone 4:20's there's 4:20 happening all the time as the band of time moves across the planet.

I don't know, i want your feedback. I like the idea of time zone 4:20's so that way someday i can celebrate 4:20 around the world- sparking up each time a time zone hits 4:20. There's lots of timezones. I like the idea of 4:20 being a clock thing too, not just happening all the time because i like a 'moment' of 4:20. 4:20 is like new years, it happens at certain times.

4:20 happening in a continual band of local current time is a trip too. Like how fast would one need to be traveling west to be in continual current local 4:20 time?
