Congratulations to Anu, Zhiyang, Suchita and colleagues on their new paper in Nature Chemical Biology describing the first acoustic biosensors. These biosensors turn on nonlinear ultrasound contrast in response to protease activity. This allows the action of enzymes such as TEV, Calpain and ClpXP to be visualized in cells deep inside the body.

Congratulations to Mohamad, Justin and Dan on their new paper in ACS Synthetic Biology describing genetic circuits allowing engineered T-cell immunotherapies to be controlled with temperature. Their work creates the possibility of controlling T-cells inside the body with brief pulses of heat delivered by focused ultrasound, magnetic hyperthermia or infrared light.

Congratulations to Dan and Echo on their publication describing modular protein domains with sharp, tunable, temperature-dependent heterodimerization. Fusing these domains with other proteins provides control over their association and localization using temperature, which can be delivered globally and locally using methods such as focused ultrasound and magnetic hyperthermia.
