Drug Discovery: On this week's Naked Scientists, drug development goes under the microscope as we explore two new ways to find the treatments of tomorrow. We find out why size is important when it comes to chemicals that can kill superbugs, and how soil bacteria hold the chemical clues to the next generation of antibiotics. Plus, how sheets of carbon can be used to reveal single atoms of hydrogen beneath the microscope, how scientists have homed in on the part of the brain linked to obsessive compulsive disorder, and why electronically tagging jellyfish can tell us a sea turtle's secrets. Plus, in Kitchen Science, we make strange and unexpected shapes with bubbles!
