Engineer tools of scientific discovery


Seeking to capitalize on the potential of a new generation of multi-functional nanoscale devices and special materials built on the scale of individual molecules, UC San Diego has established a new Department of NanoEngineering within its Jacobs School of Engineering effective July 1. Undergraduate and graduate students will learn from an interdisciplinary team of professors who are leaders in various fields of engineering, physics and chemistry and a variety of new sub-disciplines where those fields overlap.

Cytoscape is an open source bioinformatics software platform for visualizing molecular interaction networks and biological pathways and integrating these networks with annotations, gene expression profiles and other state data. Although Cytoscape was originally designed for biological research, now it is a general platform for complex network analysis and visualization.

The Jacobs School’s Cymer Center for Control Systems and Dynamics develops the mathematical and theoretical basis of control and dynamical system modeling, analysis, estimation, and design that are applicable to a wide range of engineering problems.

UC San Diego scientists have developed a technique to use laser beams as "tweezers” to trap individual atoms, microscopic particles, DNA molecules, and various cells, including sperm cells. The technique relies on the momentum inherent in laser light: when the path of laser light bends as it passes through a small transparent object such as a cell, some of the light’s momentum is transferred to the object, effectively holding, or trapping it. The brighter the laser, the more firmly the object of interest is held.

Researchers
at Scripps Institution of Oceanography are studying air-sea interactions, climate prediction, earthquakes, biodiversity in marine ecosystems, marine chemistry, and other multidisciplinary aspects of global change and the environment with advanced technologies and unique instruments, such as laser-based and sound-imaging devices, ocean devices, airplanes, remotely operated aircraft, land stations, and from satellites.

Scripps Institution of Oceanography research vessels have played a critical role in exploring Earth, supporting a wide range of seagoing science. State-of-the-art research instruments allow scientists on board to study marine life, the ocean floor, the atmosphere, and physical and chemical properties and phenomena in the oceans.

FLIP, the Floating Instrument Platform, is a 355-foot-long manned spar buoy designed as a stable research platform for oceanographic research. FLIP is towed to its operating area in the horizontal position and through ballast changes is “flipped” to the vertical position to become a stable spar buoy with a draft of 300 feet. FLIP has been used for acoustics research and in a variety of other programs including geophysics, meteorology, physical oceanography, marine mammal studies, and laser propagation experiments. FLIP is one of many state-of-the-art research instruments that allow scientists on board Scripps Institution of Oceanography vessels study marine life, the ocean floor, the atmosphere, and physical and chemical properties and phenomena in the oceans.

The torpedo-shaped “Argo” instruments contain sensors that collect vital information about the ocean's impacts on weather and climate around the world. Data from the robotic floats are being used by researchers around the world for topics such as climate and weather phenomena, changes in the salinity of the ocean, ocean-driven events such as El NiƱo and their impacts on regional weather, impacts of ocean temperature on fisheries and regional ecosystems, interactions between the ocean and monsoons, and how the oceans drive hurricanes and typhoons.
