The School of Natural Sciences annual scientific image contest celebrates the beauty in scientific discovery. Congratulations to the 2018 winners:
1st Place - Alana Semple, "Flowing Planet"
Perspective view of the inside of a model planet looking down on a hot upwelling plume (red blob) with arrows showing flow direction (size demonstrates speed). On Earth, this is where new crust is created. Warm upper mantle (warm colored arrows) and cold crust (dark blue arrows) move away from the plume, while lower mantle (shorter arrows moving toward the plume) moves toward it and up, feeding the upwelling. This model result shows that the Earth's asthenosphere can flow due to pressure differences and can even drive movement of the Earth's top layer, the crust we stand on.
2nd Place - Mariane Martinez, "Fibronectin Expression in Human Salivary Glands"
We propose to engineer a functional salivary gland for head and neck cancer patients who suffer from radiation-induced dry mouth. Our lab uses immunofluorescence images (shown here) of human salivary tissue as a blueprint to guide development of a salivary gland from primary human salivary stem/progenitor cells (hS/PCs). This image highlights the abundance of extracellular matrix protein fibronectin (red) around a salivary duct (green), which plays a crucial role in branching morphogenesis of salivary glands. Primary hS/PCs are encapsulated in 3-D hyaluronic acid-based hydrogels with various bioactive cues to promote growth and differentiation of these cells into mature salivary glands.
3rd Place - Marion Donald, "Hummingbird Silhouette"
Flighty gems delight the eye as they zip from blossom to blossom. This important process of pollination is accompanied by a transfer of microorganisms across the floral landscape. These microorganisms serve as a fingerprint of hummingbird visitation to the flowers in the Costa Rican forest. In collaboration with researchers from Stanford University and Oregon State University, we characterize these microbial players to better understand how we can detect the effects of environmental change on plants and pollinators via this microscopic signal.
