A Swiss Army Knife for Genomic Data
04-05-21
A good way to find out what a cell is doing—whether it is growing out of control as in cancers, or is under the control of an invading virus, or is simply going about the routine business of a healthy cell—is to look at its gene expression. Lior Pachter, Bren Professor of Computational Biology and Computing and Mathematical Sciences, has developed a complex software tool that enables the processing of large sets of genomic data in about 30 minutes, using the computing power of an average laptop. Like a Swiss Army knife, the tool can be used in myriad ways for different biological needs, and will help ensure the reproducibility of scientific studies. "The interdisciplinarity of our team was crucial to conceiving of and executing this project," says Pachter. "There are people in the lab who are computer scientists, biologists, engineers. Sina Booeshaghi is in the mechanical engineering department and brings the perspective of his design background and engineering." [Caltech story]

Astronomers Image Magnetic Fields at the Edge of M87's Black Hole
03-24-21
The Event Horizon Telescope (EHT) collaboration, which produced the first-ever image of a black hole, revealed a new view of the massive object at the center of the M87 galaxy: a picture of its polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of a black hole. "We are now able to see a different dimension of the light circling the M87 black hole," says Katie Bouman, Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy, Rosenberg Scholar, and co-coordinator of the EHT Imaging Working Group. "The image we reconstructed earlier showed us how bright the light was around the black hole shadow. This image is telling us about the direction of that light." [Caltech story]

Professor Bouman Featured in Inverse Magazine
03-10-21
Katie Bouman, Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy; Rosenberg Scholar, was featured in Inverse Magazine as one of the astronomers who captured the first image of a black hole. In 2019, Bouman and a group of more than 200 astronomers from all over the world managed the inconceivable: They captured the first image of a black hole, rendering the invisible visible. "Ideally, to see a black hole, we would need a telescope the size of the entire Earth," says Bouman. "We had to come up with a computational telescope that size." [Inverse article]

Paul Rothemund Places Molecule-Scale Devices in Precise Orientation
02-22-21
Paul Rothemund, Research Professor of Bioengineering, Computing and Mathematical Sciences, and Computation and Neural Systems, has developed a technique that allows him to precisely place microscopic devices formed from folded DNA molecules in not only a specific location but also in a specific orientation. This method for precisely placing and orienting DNA-based molecular devices may make it possible to use these molecular devices to power new kinds of chips that integrate molecular biosensors with optics and electronics for applications such as DNA sequencing or measuring the concentrations of thousands of proteins at once.

Adam Blank Meets Students Where They Are To Connect Across the Digital Divide
02-05-21
Long before the COVID-19 pandemic forced Caltech to shift to a model of remote learning, Adam Blank, Teaching Assistant Professor of Computing and Mathematical Sciences, focused their research on new technologies and techniques with the potential to improve student comprehension and the quality of education. Blank concentrated on making classes work remotely and helping students overcome the issues inherent in being away from campus. "The biggest thing is that I am unafraid to use a new tool, see it fail, and switch to another new tool," Blank says. "I adapted quickly—I think it's the way that I would put it—because I am used to trying new technologies all over the place and seeing what works and what doesn't." [Caltech story]
