MIT's ocean model captures diversity of underwater forests

...c diversity of marine microbes, recent advances in computational capability and a simple recognition of his own bias. "Physicists, like myself, have a bit of a reductionist view. We often shy away from the complexity of the real world in our models and prefer to reduce things to the simplest case with fewest fa...

Bones in motion: Brown scientists to create new 3-D X-ray system

...t creating the imaging technology will be a mainly computational challenge, so funding will also support substantial software development. Brown faculty and students are already at work on pilot projects to visualize pigs walking, birds flying and frogs jumping, using seed funds from Brown's Office of the Vice ...
