Bacterial Respiratory Complex

Structural model of a bacterial respiratory complex III: remember that when you respire, your complex III perspires to produce your body's energy.

Arabidopsis

Wild-type and transgenic Arabidopsis plants expressing miR156, a microRNA that promotes juvenility and increases the rate of leaf initiation

Malaria parasites

Malaria parasites (and their kin) can be viewed as minimal eukaryotes, harboring a nucleus (yellow), a secretory pathway the Golgi (purple) and specialized ‘rhotpry’ organelle (black), and two endosymbiotic organelles, the mitochondrion (red) and apicoplast (green).

Highlights

Hands-On, Minds-On Professional Development for Local Teachers

For more than 20 years, Dr. Ingrid Waldron, Dr. Lori Spindler and colleagues in the Biology Department have been offering free professional development sessions to high school and middle school life science teachers. The three-hour sessions on Saturday mornings engage participating teachers in hands-on, minds-on learning activitites and analysis and discussion learning activities which have been designed for use in their classrooms. Presentations by Biology Department faculty members enhance teacher understanding of the relevant science. Teachers receive the supplies they need to carry out the hands-on activities in their classrooms.
