Thanks to all who joined to celebrate an amazing 2018 and welcome the new year! More photos.

Congratulations to David, Danny, Audrey and collaborators on their new ultrasound imaging scheme, which uses cross-propagating sound waves to obtain maximal specificity for imaging non-linear contrast agents such as gas vesicles.

Shapiro Lab Beach Party #5! Oceanside, California. Thanks to all who came!

Congratulations to Pradeep, Sonjong, Hunter, Audrey, Vivek, Max, Jenny and Vasant on their new work showing that strong cellular paramagnetism is sufficient for magnetic manipulation and MRI contrast. Their genetic circuit makes bacteria “ultraparamagnetic” by oxidizing and chelating iron in a ferrogel.

Congratulations to Jerzy, Brian, Audrey and Dina on developing a new technology to modulate specific parts of the brain non-invasively with a combination of spatial, genetic and temporal control using ultrasound, gene delivery and small molecule drugs – featured on the cover of Nature Biomedical Engineering.

Two new articles in Neuron from Caltech (with Tomo Sato and Doris Tsao) and the University of Minnesota (led by Hongsun Guo and Hubert Lim) describe a major effect of focused ultrasound on neural circuits. Congratulations to both teams on this important step towards making focused ultrasound a mature, well-controlled tool for neuroscience.

Congratulations to George, Arash, Jerzy, Audrey and colleagues on their work introducing the concept of acoustically modulated MRI contrast agents, which address one of major limitations of MRI by taking advantage of the special magnetic and acoustic properties of gas vesicles – featured on the cover of Nature Materials.
