from Physorg.com, the sequencing of a species of fruit fly turned up something quite interesting. The DNA of Wolbachia that had been incorporated into the fruit fly’s DNA. Also this DNA is trans-scribed to make proteins. Now two things have to be considered: One, that bacterial “contamination” maybe part of the organism’s DNA. Two, how does this integrated DNA function in the host’s cell? And how does this influence evolution?

From Physorg.com, Bella Cucina Inc. has recalled their chocolate cookies because some have walnuts. As a connoisseur of chocolate, I find this story to be amusing, but then I have a dark sense of humor.
