Quoted: In the early years after the second world war, health researchers in Britain noticed a curious epidemic: people had begun dying of heart attacks in unprecedented numbers. Nobody knew why, and so a scientist in London named Jerry Morris set up a vast study to examine the heart-attack rates in people of different occupations – schoolteachers, postmen, transport workers and more.

It's even better in the details. If you click on the right-hand tabs, you get a description of each module: even cooler, each description includes a 360" rotation animation for the module.

Fun reading from The Boston Globe website.
Quoted: (...) The first thing to know is that the mind isn't a mirror, or even a passive observer of reality. Much of what we think of as being out there actually comes from in here, and is a byproduct of how the brain processes sensation. In recent years scientists have come up with a number of simple tricks that expose the artifice of our senses, so that we end up perceiving what we know isn't real - tweaking the cortex to produce something uncannily like hallucinations.

Not conclusive, but compelling new evidence from a team of researchers from the US Navy's SPAWAR research center in San Diego that something is going on. These scientists do this "low energy nuclear reactions" (LENR) work in their spare time (with a small ration from Uncle Sugar).
Link is to an AFP (Agence France-Presse) wire regarding a presentation this month at the annual meeting of the American Chemical Society. Their developments can be tracked in a series of brief papers they've had published in a very well-respected, peer-reviewed journal (Die Naturwissenschaften) over the last few years.
I think the "spare time" analogy is exactly correct, but somewhat misleading. If you want to work more than 40 hours per week as a civil servant, you can get a special dispensation to do so, but it can't be categorized as part of your regular duties.
