- Description:
- Conservation efforts start with understanding the life cycle and interactions of species. For example, orchid conservation requires understanding pollinators as well as mycorrhizal fungi because these are mutualisms orchids require. For instance, all orchids require assistance from orchid mycorrhizal fungi (OMF) to germinate and some orchid species continue to be...

- Description:
- Bioresponsive imaging probes act as beacons to allow detection, tracking, and study of otherwise invisible actors in biological systems. Understanding how these underlying systems function in their native context is essential to identifying dysfunction and generating effective remedies. Magnetic Resonance techniques are particularly interesting for this application because of the...
