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.

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]
