Many computational biologists are interested in taking gene expression data, and using that data to computationally infer the underlying regulatory network that controls the observed pattern of gene expression.

Why? Because doing the experiments to determine the structure of these regulatory networks is hard; if we could use more easily obtained data to reliably tease out the network structure, we'd be able to quickly characterize networks in unexplored cell types or in poorly studied microbes.

Bora has posted an interesting draft policy on social media from an unidentified "Big Research Institution" (BRI).

It's already stimulating some good discussion (follow the link for more links) - no surprise, since the policy guidelines contain juicy quotes like these:

All BRI social media output is the intellectual property of BRI.

Whether you are setting up new BRI social media pages within the BRI website or on an existing social media site such as Flickr or Facebook, they need to follow the BRI interactive project process.

What's the key to everlasting youth? For years now, evidence has steadily accumulated, from studies on mice, flies, worms, and even yeast, that cutting calories is the secret to a long lifespan - at least in a wide range of non-human organisms. But does this work in humans?
