The variance of a set of identical numbers (such as 6, 6, and 6) is zero.
Biologist at the Center for Population Biology of the University of California, Davis, and author of Vermeij, blind since age 3, combines autobiography and description of the evolutionary "arms race" between intertidal predator and prey species.
Majors take a rigorous set of courses with emphasis on laboratory experience and hands-on independent research. The curriculum emphasizes broad chemical training with a selection of chemistry courses and supporting courses in other related disciplines including physical and biological sciences and mathematics, along with written and verbal communication skills. An active American Chemical Society Student Affiliates chapter (the Chem Club) provides a cultural and professional environment that enriches the academic experience.
His ideas remained controversial until the 1960s, when they became widely accepted as new evidence led to the development of the concept of plate tectonics.
A paleoanthropologist with University of California, Berkeley's Laboratory for Human Evolutionary Studies, White is known for his meticulous fieldwork and analysis investigating early skeletal biology, environmental context, and behavior.
Until recently, optical resolution below ~200 nm in x-y and ~500 nm in z has been impossible due to the diffraction limit of light. This has hampered the study of many facets of developmental biology arising over small length scales, such as molecular processes in small structures such as tight junctions synapses, microfilaments, and nuclear pores. Advances in super-resolution microscopy are changing this, enabling optical examina- tion of nanometer-scale phenomena. One strategy for pushing the limits of spatial resolution employs stimulated emission to narrow the focal spot of the microscope. Called stimulated emission depletion (STED) microscopy (Hell and Wichmann, 1994), this technique uses a pair of overlapping concentric laser beams scanned together, with the first beam exciting fluorophores lying within a diffraction-limited spot and the second beam using stimulated emission to narrow this spot by preventing fluorescence at its periphery. STED microscopy can typically achieve 10-fold higher resolution than conventional fluorescence imaging, al- lowing new insights into topics as diverse as tracking synaptic vesicles in neurons, monitoring shape changes in dendritic spines, and measuring lipid dynamics in the plasma membrane (Na¨ gerl et al., 2008; Eggeling et al., 2009). Another approach for breaking the constraints of diffraction is saturated structured illumination microcrospy (SSIM) (Gustafsson, 2005; Heintzmann et al., 2002). It achieves this by illuminating the sample with a sequence of periodic patterns of high spatial frequencies that can reach satu- rating excitation intensities. Fine spatial details in the sample at less than 100 nm resolution are then extracted computationally from the raw images using deconvolution algorithms and Fourier transformations (Schermelleh et al., 2008).

Major breakthroughs in imaging are occurring in multiple technological fronts, impacting the developmental biologist’s ability to examine the nanoscale, to create large-scale tissue reconstruction, and to image cellular properties of live animals. Many methods are still in their early stages of development but as these approaches mature, we should expect to see ever more sophisticated combinations of complex fluorescent labeling strategies with in vivo or superresolution microscopy. By allowing visualization of processes and relationships within and between cells, imaging techniques are confirming that it is not just the epigenetic expression pattern or structure that is responsible for the physical properties of a developing organism. Equally important are the relationships among gene products, which produce complex, self-organizing patterns of activities. Utilizing the increasing menu of imaging techniques, highly collaborative investigations of these processes, and their underlying structural elements, are providing key insights into how an organism develops and functions.

The four-year program provides a balance of basic sciences, humanities, social sciences, engineering sciences, biological sciences, and courses in engineering design and analysis. Students choose from three engineering areas of emphasis – Biomedical, Biochemical or Environmental – and tailor courses to match. Course topics include mass transport and rate phenomena, biomaterials, reaction systems, biomechanics, environmental engineering, solid/hazardous waste management, and others. Prior to graduation, students must complete the Fundamentals of Engineering examination which qualifies the student for Engineer-in-Training registration (a prerequisite for Professional Engineer registration). A dual degree program is also available, which allows a student to earn a Bachelors of Science in Biological Engineering and Bachelor of Science in Environmental Health in five years.

''The first time I came to UGA was during my high school sophomore year for the Georgia Junior Science and Humanities Symposium. I fell in love with the beautiful campus and all the activities that were available to students. When I looked into the biological engineering program, I realized that it was a perfect match. One of my biggest achievements has been working in professor William Kisaalita’s cellular bioengineering laboratory. I have gained valuable skills that have prepared me for my career goals in medical school as well as made me a more complex and critical thinker.''
