This might come in useful at some point, with an EEG or EKG!


Breathe easy: Model and control of human respiration for computer animation
http://www.sciencedirect...le/pii/S1524070305000287



Abstract

In this paper, we detail an anatomically inspired, physically based model of the human torso designed for the visual simulation of respiration using a mixed system of rigid and deformable parts. Motion related to breath is a signature movement of the human body and an indicator for life but it has been largely overlooked by the graphics community. A novel composition of biological components is necessary to capture the key characteristics of breathing motion visible in the human trunk because the movement is generated fundamentally through the combination of both rigid bone and soft tissue. Our approach uses a simple physically based muscle element which is used throughout to drive the motion of the ribs and diaphragm as well as in other muscles, like those of the abdomen, to produce passive resistance. In addition, we describe an implementation of a straightforward method for preserving incompressible volume in deformable bodies to use in approximating the motion of the abdomen related to breath. Through the careful construction of this anatomically based torso, control for respiration becomes the generation of periodic contraction signals for a minimal set of two muscle groups. We show the flexibility of our approach through the animation of several breathing styles using our system.

Decoding the structure of bone
http://web.mit.edu/newso...ucture-of-bone-0416.html

MIT researchers decipher the molecular basis of bone’s remarkable strength and resiliency; work could lead to new treatments and materials.

The bones that support our bodies are made of remarkably complex arrangements of materials — so much so that decoding the precise structure responsible for their great strength and resilience has eluded scientists’ best efforts for decades.

But now, a team of researchers at MIT has finally unraveled the structure of bone with almost atom-by-atom precision, after many years of analysis by some of the world’s most powerful computers and comparison with laboratory experiments to confirm the computed results. The findings, from a team led by civil engineer and materials scientist Markus Buehler, are published this week in the journal Nature Communications.
