Where simulation and theory converge
For decades, scientists have believed that DNA of short lengths (150 base pairs or fewer) behaves as a relatively stiff rod—able to quiver a bit, but rarely forming a circle or tight angle...

A debate
Say you are performing biomolecular investigations that are extremely compute intensive. You have a finite amount of money and time. You could get (1) a supercomputer (fast custom CPUs and high-speed...

Can the complexities of biology be boiled down to Amazon.com-style recommendations? The examples here suggest possible pathways to an intelligent healthcare system with big data at its core.
“We have recommendations for you,” announces the website Amazon.com each time a customer signs in.
This mega-retailer analyzes billions of customers’ purchases—nearly $...
