Halloween is tomorrow, though I find it not as celebrated in Australia than in Canada. Let's not stop learning just because it is that trick or treating time of the year. To play the Halloween theme, here is an interesting post on nature's walking dead! From frozen frogs to zombie fire ants that gets their brains devoured by mother fly larvae, Mother Nature never ceases to amaze us!

Here is an exciting experiment through 21 years and 40 000 generations of E. Coli culturing later. Amazingly, some 653 mutations had occurred by the 40 000th generation. The moral of the article is that successive mutations do generally allow organisms to become more efficient dwellers in their environment. Turns out once again that Darwin was right!

The Search for Extraterrestrial Intelligence, or SETI, was founded fifty ago. Here are 10 notable moments that deserve honourable mention. Interesting enough, the invention of the Drake equation was noted as one of those key moments.
Of all listed candidates, my vote goes to the Arecibo Message. With our technology today, it is difficult to conceive that we will discover extraterrestrial life forms in the near future. We may as well let a technologically superior alien civilization track us down from our interstellar broadcasts.
What is your favourite moment?
