Obama’s Ebenezer Sermon

It’s a YouTube sensation:

While cable news shows gorge on campaign sparring, Obama’s uplifting speech is absolutely dominating YouTube. The 34-minute address from Ebenezer Baptist Church is currently the fourth most viewed video in the world on YouTube, trailing two Britney Spears clips. Not only is that unusual traffic for a long political address – people also like it. On Tuesday, viewers voted it the second most "favorited" video in the world. It also drew the second highest number of incoming links, a key indicator of web interest that drives Google page rankings.

Thinking About Whale Brains

I think it’s cached now:

We’re now wondering, essentially, what goes on in a whale’s head — and why, if it’s supposedly so smart, it doesn’t have great works to show for it. Many have argued that humans dominate the planet because we have manipulative hands that enable us to make tools, be they harpoons or missiles. What would be the cetacean equivalent? One wonders how different life on earth might have been if humans, big brains and all, had flippers instead of hands — and, perhaps, a lot more glia.

Duuude.

From Rats To Bats

A creepy experiment:

By outfitting mice with a chunk of DNA that directs wing development in bats, scientists have created rodents with abnormally long forelimbs, mimicking one of the steps in the evolution of the bat wing. Their work gives weight to the idea that variations in how genes are controlled, and not just mutations in the coding regions of genes, are a driving force in evolution.
