Katie Bouman Receives the 2021 Royal Photographic Society Progress Medal


Katie Bouman, Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy; Rosenberg Scholar; Investigator, Heritage Medical Research Institute has been selected as the 2021 Progress Medal recipient by the Royal Photographic Society. Bouman is being recognized for her work developing solutions to image such phenomenon as the first image of a black hole. Her research focuses on computational imaging and designing systems that integrate algorithms and sensor design, making it possible to observe phenomena previously difficult to capture or impossible to measure with traditional methods.

Controlling Light with a Material Three Atoms Thick


Scientists can control light more precisely than ever with a material only three atoms thick and constructed from so-called black phosphorous. In the lab of Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance, three layers of phosphorous atoms were used to create a material for polarizing light that is tunable, precise, and extremely thin. Black phosphorous tech could revolutionize telecommunications by vastly improving light signals sent through fiber-optic cables. The technology could also open the door to a light-based replacement for Wi-Fi, something researchers in the field refer to as Li-Fi. "Increasingly, we're going to be looking at light-wave communications in free space," Atwater says. "Lighting like this very cool-looking lamp above my desk doesn't carry any communication signal. It just provides light. But there's no reason that you couldn't sit in a future Starbucks and have your laptop taking a light signal for its wireless communication rather than a radio signal. It's not quite here yet, but when it gets here, it will be at least a hundred times faster than Wi-Fi." [Caltech story]

Dabiri Appointed to Secretary of Energy Advisory Board


The Department of Energy (DOE) has announced that John O. Dabiri, the Centennial Professor of Aeronautics and Mechanical Engineering, has been appointed to the Secretary of Energy Advisory Board (SEAB). The SEAB meets quarterly to advise Secretary of Energy Jennifer Granholm on how best to achieve the department's priorities and offer recommendations on scientific, technical, and programmatic issues relating to the DOE's mission. "I'm excited to work with the secretary to ensure strong support for fundamental science research, especially in areas where the technological application might be hard to predict today," Dabiri said. "Secretary Granholm's vision to accelerate deployment of climate solutions matches my own sense of urgency to advance sustainability. I'm honored by the opportunity provide advice where it can be helpful for achieving that goal." [Caltech story]

LEONARDO, the Bipedal Robot, Can Ride a Skateboard and Walk a Slackline


Researchers have built a bipedal robot that combines walking with flying to create a new type of locomotion, making it exceptionally nimble and capable of complex movements. "We drew inspiration from nature. Think about the way birds are able to flap and hop to navigate telephone lines," says Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems; Jet Propulsion Laboratory Research Scientist. "A complex yet intriguing behavior happens as birds move between walking and flying. We wanted to understand and learn from that." A paper titled "A bipedal walking robot that can fly, slackline, and skateboard" about the LEO robot was published online on October 6 and was featured on the October 2021 cover of Science Robotics.

Dabiri Appointed to President's Council of Advisors on Science and Technology


President Joe Biden has announced the appointment of John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, to the President's Council of Advisors on Science and Technology (PCAST). Presidents have established advisory committees of scientists, engineers, and health professionals ever since Franklin D. Roosevelt created his Science Advisory Board in 1933. "We're here to provide whatever input the president needs," Dabiri says. "My understanding is that we'll be meeting pretty frequently, as the president wants science to be a big part of his decision-making process." [Caltech story]

Mice Can Learn Much Faster than Previously Thought


Researchers have now conducted a study in which they measured how mice navigate a complicated labyrinth, suggesting a new framework with which to study complex animal behaviors and learning. The mice rapidly learned how to navigate this unfamiliar environment about 1,000 times faster than mice generally learn simple yet unnatural tasks. The research is a collaboration between the laboratories of Markus Meister, Anne P. and Benjamin F. Biaggini Professor of Biological Sciences, and Pietro Perona, Allen E. Puckett Professor of Electrical Engineering. [Caltech story]

The Science of Underground Kingdoms


A team led by the laboratory of Jose Andrade, George W. Housner Professor of Civil and Mechanical Engineering; Cecil and Sally Drinkward Leadership Chair, Department of Mechanical and Civil Engineering; Executive Officer for Mechanical and Civil Engineering, studied the digging habits of ants and uncovered the mechanisms guiding them. Before beginning this research, Andrade had a big question he wanted to answer: Do ants "know" how to dig tunnels, or are they just blindly digging? "I got inspired by these exhumed ant nests where they pour plastic or molten metal into them and you see these vast tunnel systems that are incredibly impressive," Andrade says. He enlisted the help of Joe Parker, Assistant Professor of Biology and Biological Engineering, whose research focuses on ants and their ecological relationships with other species. "What Jose and his team needed was somebody who works with ants and understands the adaptive, collective behaviors of these social insects to give them some context for what they were doing," Parker says.
