Wearable Sweat Sensor Detects Gout-Causing Compounds

11-25-19

In a new paper published in Nature Biotechnology, Wei Gao, Assistant Professor of Medical Engineering, describes a mass-producible wearable sensor that can monitor levels of metabolites and nutrients in a person's blood by analyzing their sweat. Gao's sweat sensor is more sensitive than current devices and can detect sweat compounds of much lower concentrations, in addition to being easier to manufacture. "Considering that abnormal circulating nutrients and metabolites are related to a number of health conditions, the information collected from such wearable sensors will be invaluable for both research and medical treatment," Gao says.

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]

Jing Li Receives AAAR Sheldon Friedlander Award

10-28-19

Jing Li, a postdoctoral scholar working with Professor Michael R. Hoffmann, is the recipient of the 2019 Sheldon K. Friedlander Award from the American Association of Aerosol Research (AAAR). The award recognizes an outstanding dissertation by an individual who has earned a doctoral degree in any discipline related to the physical, biomedical or engineering sciences in the field of aerosol science and technology. In her doctoral thesis, Jing focused on studying the global PM-borne biologicals and their toxicity, more broadly in bioaerosol field. Her dissertation work raises the awareness of airborne transmission of antibiotic resistance genes (ARGs), as well as global differences of local source-specific PM toxicity. [Past recipients]

Caltech Announces the Schmidt Academy for Software Engineering

10-10-19

Caltech has launched the Schmidt Academy for Software Engineering to train the next generation of science-savvy software engineers and set new standards in scientific software. "This is a recognition that computing, software, and machine learning are going to play a very big role in science. Because Caltech is small and collaborative, we have the opportunity to really make a push in that direction," says Kaushik Bhattacharya, the Howell N. Tyson, Sr., Professor of Mechanics and Materials Science and vice provost. [Caltech release]
