  1. Computers Seek The Call Of An Extinct Bird

    Buran writes: "As a self-proclaimed geek and a relative (and fascinated!) newcomer to the world of birding, I found this article in the New York Times Science Tuesday about the search for the ivory-billed woodpecker to be rather interesting. The bird, which was listed as extinct in 1997, has not been definitively sighted since the 1950s, but a recent reported sighting (in 1999) has led to a redoubled effort to find it. The geek side is this: Since it would be impractical for a human to sift through 5,000 hours of recorded sound (two and a half years, they estmate) to listen for the bird's distinctive call, the Cornell researchers are working on algorithms that can pick out interesting sections of digitally recorded sound, taken from microphones placed throughout the study area, for a human (who can outdo a computer any day at making the final determination) to review. I am hopeful that the search will return a positive result."

  2. Space Pictures From Near and Far

    Buran writes: "The BBC News has a fine story about the how our galaxy looks from the outside according to the 2-Micron All-Sky Survey (2MASS). The article describes the shape of our galaxy (a barred spiral; all those books showing concept paintings of a regular spiral galaxy will be out of date now) and how the survey was done (near-infrared measurements of 500 million carbon stars). For the first time, we can see the center of our own Milky Way. All our worldly troubles seem so small..." That takes care of the big picture; Chris McKinstry has submitted news of much closer but just as exciting shots of Saturn -- read below for more on those.

    mindpixel writes: "I was very excited when I saw this amazing shot of Saturn come up on the control room monitors of the VLT in November, and I'm even more excited that as of today the image is finally public. It is possibly the sharpest view of Saturn's ring system ever achieved from a ground-based observatory. All of us here at the observatory are quite proud of it, especially the NAOS-CONICA team."
