Computing with Biochemical Circuits Made Easy

02-23-17

Lulu Qian, Assistant Professor of Bioengineering, is working to create circuits using not the usual silicon transistors but strands of DNA. "A DNA circuit could add 'smarts' to chemicals, medicines, or materials by making their functions responsive to the changes in their environments," Qian says. "Importantly, these adaptive functions can be programmed by humans." [Caltech story]

A Birder in the Hand: Mobile Phone App Can Recognize Birds From Photos

12-14-16

Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleagues have developed the Merlin Bird Photo ID mobile app which uses machine-learning technology to identify hundreds of North American bird species it "sees" in photos. "This app is the culmination of seven years of our students' hard work and is propelled by the tremendous progress that computer-vision and machine-learning scientists are making around the world," says Professor Perona. "A machine that recognizes objects in images, like humans do, was a distant dream when I was a graduate student and now it's finally happening." [Caltech story]

Visualization Brings Data to Life

10-28-16

Students participating in Caltech's Data Visualization program aim to tackle cumbersome data-manipulation problem such as how to drive a rover on Mars from a command room on Earth. One of the goals of the program is to develop innovative software to streamline the ways in which scientists and engineers visually manipulate their data. "We use a human-centered design methodology," Professor Mushkin says. "Design students create sketches and ask the researchers to 'interact' with them by pointing, talking, shuffling, and annotating the paper, while computer science students create rough drafts of a variety of possible approaches to coding the visualization."

Practical Mathematics: An Interview with Andrew Stuart

10-28-16

Professor Andrew Stuart is interested in how the current era of data acquisition interacts with centuries of human intellectual development of mathematical models that describe the world around us. His research is informed by—and has applications for—diverse arenas such as weather prediction, carbon sequestration, personalized medicine, and crowd forecasting. [Interview with Prof. Stuart]

Schroeder
Improving Computer Graphics with Quantum Mechanics

07-27-16

The Schrödinger equation, the basic description of quantum mechanical behavior, can be used to describe the motion of superfluids—fluids, supercooled to temperatures near absolute zero, that behave as though they are without viscosity. Professor Peter Schröder and his colleagues realized that the same equation with some small modifications can also be used to describe vorticity dominated phenomena of fluids at the macroscopic level--from smoke gently rising from a flame to the concentrated vorticity of a twister.

Counting L.A.’s Trees

07-27-16

Professor Pietro Perona, has developed a method using Google Earth and Google Street View to count the trees in the city of Los Angeles. The process of counting the trees using human tree counters is very expensive and would cost about $3 million today. The last time the city did such counting was more than two decades ago and at the time there were 700,000 street trees. Perona has tested the methodology in a section of Pasadena where the city recently commissioned a sidewalk survey. By comparing the results to the known inventory, he determined that the computer was about 80% accurate. [LA Times story] [KPCC story]

A Microscopic Glowing Van Gogh

07-12-16

Paul Rothemund, Research Professor of Bioengineering, Computing and Mathematical Sciences, and Computation and Neural Systems, and colleagues have developed a technique that allows manmade DNA shapes to be placed wherever desired; to within a margin of error of just 20 nanometers. This technique removes a major hurdle for the large-scale integration of molecular devices on chips. As a demonstration of the technique’s capabilities the group has created one of the world's smallest reproductions of Vincent van Gogh's The Starry Night. [Caltech story]
