Ultrasound Can Selectively Kill Cancer Cells
02-05-20
Michael Ortiz, Frank and Ora Lee Marble Professor of Aeronautics and Mechanical Engineering, Emeritus, and Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Bioinspired Engineering; Booth-Kresa Leadership Chair, Center for Autonomous Systems and Technologies; Director, Graduate Aerospace Laboratories; Director, Center for Autonomous Systems and Technologies, are exploring a new technique that could offer a targeted approach to fighting cancer. Low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. In the past, ultrasound waves have been used as a cancer treatment with high-intensity bursts resulting in killing cancer and normal cells. [Caltech story]

Professor Rosakis Elected Laureate of the Aurel Stodola Lecture
02-05-20
Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering has been elected as the Laureate of the Aurel Stodola Lecture and presented with the Aurel Stodola Medal. The Aurel Stodola Lecture Series commemorates the contributions of Professor Aurel Stodola in the early 20th century whose work on applied thermodynamics has guided many engineers and engineering developments worldwide. "Ares Rosakis possesses this unique ability to develop new experimental methods to make extremely fast mechanical processes (such as those occurring during earthquakes) tangible and observable in the laboratory," says Bradley Nelson, Professor of Robotics and Intelligent Systems and Head of D-MAVT.

Bionic Jellyfish Swim Faster and More Efficiently
01-30-20
John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, has developed a tiny prosthetic that enables jellyfish to swim faster and more efficiently than they normally do, without stressing the animals. Dabiri is envisioning a future in which jellyfish equipped with sensors could be directed to explore and record information about the ocean. "Only five to 10 percent of the volume of the ocean has been explored, so we want to take advantage of the fact that jellyfish are everywhere already to make a leap from ship-based measurements, which are limited in number due to their high cost," Dabiri says. "If we can find a way to direct these jellyfish and also equip them with sensors to track things like ocean temperature, salinity, oxygen levels, and so on, we could create a truly global ocean network where each of the jellyfish robots costs a few dollars to instrument and feeds themselves energy from prey already in the ocean."

Bees "Surf" Atop Water
11-20-19
Chris Roh, Research Engineer, working with Professor Morteza Gharib, discovered a unique way that bees navigate the interface between water and air. When a bee lands on water, the water sticks to its wings, robbing it of the ability to fly. However, that stickiness allows the bee to drag water, creating waves that propel it forward."I was very excited to see this behavior and so I brought the honeybee back to the lab to take a look at it more closely," Roh says.

Professor Ortiz Receives John von Neumann Medal
08-09-19
Michael Ortiz, Frank and Ora Lee Marble Professor of Aeronautics and Mechanical Engineering, is the recipient of the 2019 U.S. Association for Computational Mechanics (USACM) John von Neumann Medal "for pioneering and sustained contributions in developing computational methods to elucidate material behavior across length and time scales (atomistic to continuum), development of the quasi-continuum method, and authorship of highly cited articles." This is highest award given by USACM. It honors individuals who have made outstanding, sustained contributions in the field of computational mechanics generally over periods representing substantial portions of their professional careers.
