Ultrasound Can Selectively Kill Cancer Cells

02-05-20

Professor Michael Ortiz and Professor Morteza Gharib 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 McKeon Unlocked Secrets Behind Turbulence

11-06-19

Beverley McKeon, Theodore von Karman Professor of Aeronautics, has unlocked some of the secrets behind turbulence, a much-studied but difficult-to-pin-down phenomenon that mixes fluids when they flow past a solid boundary. "We knew that, underlying these very complicated structures, there had to be a very simple pattern. We just didn't know what that pattern was until now," says McKeon. [Caltech story]

New Polymer Heart Valve Implanted in First Patient

09-18-19

Professor Morteza Gharib, has designed a new generation of heart valves that are longer-lasting, cost less to manufacture, and are more biocompatible than options that are currently available to patients. One of the new valves has been implanted into a human for the first time. "This is among my proudest moments. Creating something with the potential to save and improve lives is one of the reasons I became an engineer," Gharib says. [Caltech release]
