Congratulations to Hunter, Pradeep, Aadyot, Audrey and our collaborators at Harvard on a new study using NV diamond magnetometry to examine the microscale origins of MRI contrast. A preprint describing this work has been posted on arXiv.

Congratulations to Anupama, Arash, Suchita, Audrey, Ray and David on their cover article in the September issue of ACS Nano! Their work describes how gas vesicles can be engineered at the level of their protein composition and sequence to exhibit new acoustic properties and molecular targeting.
