Over time, great slabs of oceanic crust were pulled down, or subducted, into the Earth's ma...

Protein engineered to detect nerve gas

...akes at most a day to calculate a set of candidate structures and perhaps a week to construct them. So, in the event of the deployment of a new chemical threat, it might take in principle only weeks to develop a sensor system for it. We're now working to develop an automated laboratory process into a system to ...

Biologists discover nerve activity, not just genetics controls kinds of neurotransmitters produced

... propose that while genes control the formation of structures that produce electrical activity in nerve cells, the activity itself can determine what neurotransmitters are produced. According to Spitzer, this could provide flexibility for the growth and operation of the nervous system. "Biology is a little slop...
