This molecular illustration shows the components involved in the release of insulin from a pancreatic beta-cell during a period of elevated glucose-levels. The insulin molecules will go on to bind to insulin-receptors on other cells that allow glucose to enter and be used for energy.

This image is half of a raccoon mandible that was recovered in marshes along the Georgia coast. Nerve innervation and arterial supply for the teeth can be seen entering through the mandibular foramen. A section of the body has been removed to reveal the structures in the mandibular canal. The sample is missing the incisors.

This molecular illustration shows the steps involved in building the ‘membrane-attack complex’ (MAC) during an immune response against an invading bacterium. A transmembrane channel is formed when up to 16 C9 molecules are added, thus disrupting the outer membrane (the complete pore was halved for the sake of the illustration).
