How Do You Keep Up With Science Developments? 337
malraid writes "As a nerd who used to love science back in high school (specially physics), I now find myself completely disconnected from any and all scientific developments and news. How do you try to stay up to date with scientific developments? Science journals? Whatever makes it into Slashdot's front page? Books? Magazines? I'm looking for something engaging and informative, for not something that will require me to go and get a PhD just to be able to comprehend."

Scientific American is amongst the least accessible of this type imo.
Not sure what you mean by "accessible", because I find it very readable in every subject area -- physics, biology, geology, what have you -- even though I have little or no training in any of those beyond some basic high school or college classes. (my degree is in C.S.)
And I still find new ideas and concepts in there that just knock my socks off -- the small-molecule theory of the origin of life, for example. This even though I've been reading it and Science News for nearly 30 years now.

I hate to have to repeat what is indisputable fact, but Evolution and Global Warming are not seriously contested within Science. The Universe is currently estimated to be about 13 billion years old, while the Earth formed some 4.5 billion years ago (knowledge made possible by advances in physics). Most life began about 500 million years ago with the Cambrian Explosion, most likely instigated by a dramatic increase of oxygen in the atmosphere. Humans evolved as a particularly virulent branch of hominids, and we as a species are most notable due to our advanced culture, which I am sad to add is still not sustainable.
What is not particularly well known is how serious the Energy Crisis is, how it is affecting the economy, and what is likely to be the only practical solution in the short term. The central issue with energy is how much one gets out of what one puts in. This principle is known as Net Energy. Our return from our energy system has probably been in decline for some 40 years- or about the time when domestic US oil production peaked. Since then, on essentially borrowed time, we have failed to come to terms with this problem. As energy becomes more expensive to harvest, more of the economy must be devoted to harnessing that energy. To further exasperate things, the dominate form of energy today, fossil fuels, basically involves taking what was once sequestered from the atmosphere, harvesting it for energy, and releasing a particular byproduct back into the atmosphere (CO2). This gas acts in such a way as to cause the climate system to retain more energy, which in turn alters the weather. Long-term, the effects are very likely to be catastrophic for civilization, which has largely adapted to inhabiting coastlines.
Since renewables solve, in theory, the carbon problem, many have seized upon them as the solution. What they do not solve is the net energy problem, so while you can “farm” energy in a bewildering variety of ways, they are fundamentally energy sparse, and so energy will remain expensive, regardless of what is done. This conundrum has basically driven our society over the edge with one side trying to impose an unworkable solution on a completely non-compliant and denying opposition.
Nuclear energy remains the only source with the energy density to solve this problem. Unfortunately, the current technology is expensive, fault-prone, inefficient, non-scalable, inflexible, and dirty, all of which has fuelled detractors. Many nuclear alternatives have been proposed, but they remain to date completely unproven (FocusFusion, General Fusion, TriAlpha) or distant and expensive (ITER, NIF).
We do have a technology that is proven, affordable, clean, flexible, efficient, and scalable, but we have to do some work to get it ready for commercialization. Back in the 60s, some intrepid scientists at Oak Ridge National Laboratories invented an amazing machine that used a liquid fuel based on U-233 that could be produced from the abundant element thorium. The beauty of this invention is that it solves many of the problems that plague our current technology, delivering an inherently safe and super efficient source of energy that will last indefinitely. China already announced earlier this year that they are pursuing Green Nuclear, and it would be prudent for us to join the Thorium Race at this juncture. Doing so almost guarantees that we will eventually have the resources to end poverty, provide social services to everyone, ensure world peace, and have flying cars! This isn’t science fiction, but it could be our reality if we act with intelligence.
