The year’s highest science honor for high school students was awarded today to biochemistry research on cancer stem cells and an innovative use of gaming technology in the area of leg injuries and prosthetics in the 2011 Siemens Competition in Math, Science & Technology, America’s premier science research competition for high school students. Administered by the College Board, the Siemens Competition is a signature program of the Siemens Foundation, which supports science, technology, engineering and mathematics (STEM) education. The thirteenth annual awards were presented this morning at The George Washington University, host of the 2011 Siemens Competition National Finals. Angela Zhang, a senior at Monta Vista High School in Cupertino, California, won the 0000 Grand Prize in the Individual category for using nanotechnology to eradicate cancer stem cells. Ziyuan Liu and Cassee Cain, seniors at Oak Ridge High School in Oak Ridge, Tennessee, will share the 0000 Grand Prize in the Team category for using new gaming technology to analyze human walking patterns, work that could ultimately be used in prosthesis design for amputees.

This animation illustrates how breast stem cells respond to steroid hormone despite the cells not having any steroid receptors. The animation illustrates the research published in Nature (Vol 465, Issue 7299, 2010) by the laboratory of Jane Visvader and Geoffrey Lindeman. See our other animation, Breast Stem Cells, for a more detailed explanation of stem cell function.

Planaria are non-parasitic flatworms of the biological family Planariidae, belonging to the order Seriata. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas. These animals move by beating cilia on the ventral dermis, allowing them to glide along on a film of mucus. Some move by undulations of the whole body by the contractions of muscles built into the body membrane. They exhibit an extraordinary ability to regenerate lost body parts.
