A well-known related theory is that blue light has the greatest effect. I'm currently (self-)experimenting with reddening my home desktop LCDs as much as possible in hardware. However, effects of this treatment on when I actually fall asleep have so far been non-obvious. I would need to more carefully collect data and experiment with undoing the reddening for a while to be sure, but if the effect is small enough that I can't perceive it directly, then the effect is not worth the hassle of avoiding blue light. Relatedly, an N=12 study found that, "as expected, only the blue light reduced nocturnal melatonin. In contrast, both blue and red lights affected cortisol levels."
On the other hand, reddened screens at night are easier on my eyes, whether they help me sleep or not.

But if the Lord has been pleased to assist us by the work and ministry of the ungodly in physics, dialectics, mathematics, and other similar sciences, let us avail ourselves of it, lest, by neglecting the gifts of God spontaneously offered to us, we be justly punished for our sloth.

My main point is that the differences were small (probably statistically insignificant), but if you're curious about the "negative" part... On average, respondents (who were all be about 25 years old in 2012) with bachelor's degrees or higher were slightly less satisfied with their jobs than high-school drop-outs; both of these groups were more satisfied than college drop-outs.
On the other hand, education is strongly correlated (see page 17) with something the study names "work support," which is a linear combination of multiple survey responses that the authors identified through principal factor analysis (page A-13). (I couldn't find any explanation for why they call this quantity "work support.")

The appliances of 2014 will have no electric cords, of course, for they will be powered by long- lived batteries running on radioisotopes. The isotopes will not be expensive for they will be by- products of the fission-power plants which, by 2014, will be supplying well over half the power needs of humanity. But once the isotype batteries are used up they will be disposed of only through authorized agents of the manufacturer.What might have been. Today I can read about the 30-year RTG in the Chinese moon rover:
Using plutonium-238, the battery will be able to power the 100-kilogram vehicle for more than 30 years, said Ouyang Ziyuan, chief scientist of China's lunar exploration program.But where's my nuclear powered car? I'll settle for a 90Sr model...
"The nuclear power system will make China the third country apart from the United States and Russia to be able to apply nuclear technology to space exploration," Ouyang said.
The moon rover is China's most advanced robot with complete automatic navigation and operations. It will be powered by the sun during daytime and by nuclear power during the night.

The Lord God said to the serpent,"Because you have done this, cursed are you above all livestock and above all beasts of the field; on your belly you shall go, and dust you shall eat all the days of your life. I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel."
The Lord says to my Lord:"Sit at my right hand, until I make your enemies your footstool."
The Lord says,"It is too light a thing that you should be my servant to raise up the tribes of Jacob and to bring back the preserved of Israel; I will make you as a light for the nations, that my salvation may reach to the end of the earth."
So shall he sprinkle many nations; kings shall shut their mouths because of him; for that which has not been told them they see, and that which they have not heard they understand.
And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
The true light, which gives light to everyone, was coming into the world.
"Behold, I am coming soon, bringing my recompense with me, to repay each one for what he has done. I am the Alpha and the Omega, the first and the last, the beginning and the end."
The Spirit and the Bride say, "Come." And let the one who hears say, "Come." And let the one who is thirsty come; let the one who desires take the water of life without price.

While more architectural imagery is highly important in understanding the creation and the notion of design is more appropriate in such a context, such imagery tends to be focused principally upon the inanimate creation... When we are dealing with the land animals in particular, what we see is a far more mediated mode of creation—‘let the earth bring forth’... In many respects, God’s creative work in this case is less akin to an external action upon passive material as an internal empowering of a process that arises within nature itself.

I read recently of an ingenious plan put forward by Russian engineers, for making the White Sea and the northern coasts of Siberia warm, by putting a dam across the Kara Sea.I wonder whatever happened to that plan. Is it obviously wrong or infeasible in hindsight? Was the dam to go merely across the Kara Strait, or was the plan to build a ~500km dam across the Kara Sea?
