Watson Lecture: Mory Gharib (PhD '83) on the "Engima of the Heart"

03-02-23

Our circulatory system's 500 million years of evolution is on full display during the nine months of human embryonic heart development. The hallmark of this evolution is a beating, complex, autonomous muscular pump that sustains life. In this lecture, Mory Gharib (PhD '83), the Hans W. Liepmann Professor of Aeronautics and Medical Engineering, explains the wave system established by the beating heart that moves through the human body, which can provide a window to the health of the cardiovascular system and early diagnoses of its devastating diseases by utilizing modern data science.

Leonardo da Vinci's Forgotten Experiments Explored Gravity as a Form of Acceleration

02-14-23

Engineers from Caltech have discovered that Leonardo da Vinci's understanding of gravity—though not wholly accurate—was centuries ahead of his time. In an article published in the journal Leonardo, the researchers draw upon a fresh look at one of da Vinci's notebooks to show that the famed polymath had devised experiments to demonstrate that gravity is a form of acceleration—and that he further modeled the gravitational constant to around 97 percent accuracy.

Launch of a new era or flights of fancy? Branson, Bezos ventures may open space travel to all

07-28-21

The space travel pursuits by British entrepreneur Richard Branson and Amazon founder Jeff Bezos are evoking awe and wonder among enthusiasts and even casual observers, conjuring visions of a day when such flights may become fairly ordinary. After reaching the edge of space with a five-person crew aboard a spacecraft from his company Virgin Galactic on July 11, Branson said he wanted to “make space more accessible to all.’’ Other advantages include the possibility they could spur new developments that may enhance airline travel and considerably shorten flight times. "Within five years, I would say the people who can afford to fly first class around the world would be able to afford a (space) flight," said 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.

How Do You Test a Helicopter Bound for Mars?

04-29-21

Caltech grad students helped JPL build a custom wind tunnel in a vacuum chamber for the Mars Ingenuity helicopter. The Ingenuity helicopter may be the first vehicle ever to fly on Mars, but Mars was not the first place it has ever flown. Before packaging it up and blasting it to the Red Planet, engineers at JPL gave the helicopter a trial run in a special wind tunnel. The fan array was designed and built by JPL engineers with input from Chris Dougherty and Marcel Veismann, who are currently working with Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Bioinspired Engineering and Booth-Kresa Leadership Chair of Caltech's Center for Autonomous Systems and Technologies (CAST). Jason Rabinovitch, who was a mechanical engineer at JPL working on testing the helicopter, reached out to the CAST team in 2017. "I'd earned my PhD at GALCIT, so I was aware of CAST and its facilities," says Rabinovitch. [Caltech story]

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]

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.

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]
