I spent most of the weekend away from my desk, so I apologize for not posting submissions that came through. I'll get them up over the next few hours.

Here are a few things we should have discussed over the weekend:

According to the July 20th edition of The Astrophysical Journal over 200-extrasolar planets have been located.
For those looking to understand the (potentially) coming "Hydrogen Economy", here is a solid analysis of how such a power grid could work.
And Scientific American probes the minds of chess grandmasters to analyze what makes one an "Expert" at something, and how this analysis can carry over into cognitive science beyond "rook to king's bishop 4".

Finally some heavyweights of science had birthdays over the weekend, including:
Friedrich Bessel, who was the first to use parallax in calculating the distance to a star.
Gregor Mendel, the father of genetic theory.
And Gustav Hertz, who won the Nobel Prize in Physics in 1925.
