As someone with a degree (admittedly ancient and unpractised) in medical science maybe I can be of some help here.
It is my understanding that there is little relationship between dietary intake of cholesterol and the cholesterol levels measured in the blood, even the so-called "Bad Cholesterol". Sorry, I can't provide a reference.
Confounding factors may be influencing the result of this study; for example, the frequent egg eaters (perhaps at breakfast) may tend to be the ones that like a lot of meat at their evening meal, perhaps with gravy. The authors of the study adjusted for some things, but I didn't see any indication that they separated out these factors.

"can generate up to 70 MW of electric energy and 50 Gcal/hr of heat energy..."
That should be 70MW of electric POWER.
50Gcal/hr comes out to almost 58MW of heating power, which they have to remove from the boat lest the heat exchangers, and probably other components, overheat.
I guess they can just dump the heat into the water where they dock and introduce tropical fish there, and charge to snorkel with the fish.:-)
You may not have to worry too much about this one being too political in the sense of pushing the Culture's ideals. As I recall most of the action takes place in a region where the culture has little influence.
The story is set in a system quite apart from most of Banks's science fiction and revolves around a strong female lead character (Sharrow) whose adversaries force her to reassemble her old war buddies for the flight/fight of their lives.
My understanding is that the main limitation for many satellites is propellant/fuel for station-keeping and any other manoeuvering. The Emdrive could eliminate moving parts like valves and give us longer-lasting satellites, if nothing else.
LOL I agree, the publishing houses have had it their way almost since Gutenberg's time. It's not like Google is putting whole books that are still under copyright out there for anyone to grab.

The trusting trust problem is a serious one, and if you can't rely on being able to build a byte-for-byte identical unit from source, you can't really have any confidence that you're running code that represents what the authors intended.

Microway have been supplying high quality, high performance systems for decades and they should have figured out how to do it right by now. If I had the spare money, it's what I would choose.
For your CFD software, you might consider the open source OpenFOAM system.
Be careful with the memory subsystem to select DIMMs that will run at the maximum rate of the system. Quad-rank DIMMs typically run slower. This may mean you can't use the full range of 1TB dram that this system can address.
You could do a lot worse than to buy an HP ZBook I7 G2 Mobile Workstation.. Some of HP's earlier workstations could be ordered with Linux preinstalled. The current machines have Win 8.1, I think, which can be downgraded to Win 7. One thing you may have problems with is switching between the on-die GPU and the discrete GPU. By all means run Linux in a VM under Windows.
I understand that Kodak makes some archival-quality DVD-R media which are for exactly this sort of purpose. You could do a lot worse than to try that. You can store them in a cool, dry place and forget about them.
And release them under an open source license. Perhaps also organise a group of
people to continue developing the content.
I have in mind Mary L. Boas' book Mathematical Methods in the Physical Sciences.
Mary L. Boas died a few years ago and her book is in its third edition. I have no
idea what the publishers plan to do with it, but surely those who own the rights to
it would be persuadable by the appropriate application of money.
The military probably has huge stockpiles of potato powder that they feed the troops.
Raid it, and find out where they get it from, and use it. Probably it'll eventually increase the cost
of 'French Fries' at McDonalds, which would be no bad thing, in my not-so-humble opinion.

Although I don't know the language myself, and are therefore not qualified to wholeheartedly recommend it, your denial of Python as an appropriate language to learn seems full of holes.
The anonymous questioner seeks to know which language to become "native to", which means that it should be a general purpose language capable of doing lots of stuff quite well. He (or she) says they've worked in the industry and have quite a bit of experience in different programming languages. With the exception of performance, native Python code can do quite a lot very elegantly, or so I am led to believe. In addition it can interface to lower level languages (C or C++ in particular) for doing performance-critical work.
Just recently I encountered a project I want to use whose main implementation language is Python, but for which the time-critical portions are done in another language.
I now find myself wishing I made an effort to become fluent in Python after I saw the following when it was first posted:
The fact that the thing is not engineered for high temperatures may limit its efficiency, but does not necessarily mean that there isn't a large generation of power in the system. It just means that there would be a much larger flow of the fluid to carry the heat away from the source and the fluid (light water, I think) could be at a low pressure. An observer saw a thermometer on the outgoing side registering about 109 degrees Centigrade. Not enough to melt many engineering plastics. The heat was reportedly dumped using some sort of radiator, and the fluid was recirculated to the cells.
I find it highly suspicious, however, that there was a generator set, rated at perhaps 500KW, running continuously during the test. Rossi's statement on this is that the genset was required to run pumps and instrumentation while the system was in 'self-sustaining' mode. It was also used to pump 400KW of heat into the system to raise the temperature to boiling point and get it there.
Time will tell, I guess. Markets will fluctuate. Someone will make a lot of money.
Let's hope it's real and Rossi builds and sells successful E-cats. It would change the world for the better.

I got thanked for a contribution of a couple of lines of my public
domain code that made it into OpenOffice. I suspect it was sarcastic.
One small nit - the PC speaker wasn't memory mapped - it was in I/O space.
The technique does indeed show promise for pest species.
I just hope that the researchers have a good handle on all the
ways it can go pear-shaped, including jumping species.

Not 3 arks, you use 3 but you make 4 and put one into storage.
Maybe one of the 3 won't pass acceptance testing.

Several labs have detected the effect, now NASA has shown it happens in a vacuum.
Theorists must be scrambling to make sense of it.

He/She freely states "never really was more than a hack" and being out-of-date, and you call "noobie"?
"Now I find myself wanting to really focus on coding for personal reasons."
Perhaps it's _none_of_our_business_ what the application(s) is/are.
