Narrator: This is Science Today. An expert on the biomechanics of head and neck injuries is hoping to build a more realistic model of a baby's skull and brain to better determine the forces involved in accidental falls versus child abuse - particularly, shaken baby syndrome. Mechanical engineer Werner Goldsmith, of the University of California, Berkeley says the brain injuries that lead many prosecutors to file charges of child abuse may also be caused by falls or even chronic bleeding in the brain.
Goldsmith: I am convinced that people have been convicted of child abuse that were innocent. I'm not saying that there are a large number, but there are cases I've examined where I know mathematically substantiated, that the fall caused the death or severe brain injury.
Narrator: Goldsmith says there should be more collaboration between pediatricians and biomechanicians.
Goldsmith: If we can get the two sides to come together, I think it will be a wonderful thing for science, for medicine and for humanity.Narrator: For Science Today, I'm Larissa Branin.
