Polarization Imaging Apparatus

A polarization imaging apparatus has shown promise as a prototype of instruments for medical imaging with contrast greater than that achievable by use of non-polarized light. The underlying principles of design and operation are derived from observations that light interacts with tissue ultrastructures that affect...

Question of the Week
Could a sin tax make people eat healthier?

This week's question concerns the U.S.'s ongoing efforts to encourage healthier eating. States across the nation are beginning to impose "sin taxes" on fat and sugar to dissuade people from eating junk food. The thought is that if you make it cheaper, people will eat more of it, more expensive and...
