An Experiment in Graduate Education: A Marine Science Adventure across the Indian Ocean

In the fall of 1964, Stanford University’s R/V Te Vega Cruise 5 crossed the equatorial Indian Ocean from Mombasa to Singapore, one of many ships participating in the International Indian Ocean Expedition. The cruise achieved two goals: (1) it provided hands-on oceanography training for graduate students in marine sciences, and (2) it documented the deep scattering layers of the Indian Ocean, only poorly known at the time. Taking place on the other side of the globe from the United States, the cruise also exposed students to cultural and personal experiences that shaped their lives and professions. It demonstrated the importance of experiential learning for future ocean scientists

Fluorescent proteins generate a genetic color polymorphism and counteract oxidative stress in intertidal sea anemones.

Fluorescent proteins (FPs) are ubiquitous tools in research, yet their endogenous functions in nature are poorly understood. In this work, we describe a combination of functions for FPs in a clade of intertidal sea anemones whose FPs control a genetic color polymorphism together with the ability to combat oxidative stress. Focusing on the underlying genetics of a fluorescent green "Neon" color morph, we show that allelic differences in a single FP gene generate its strong and vibrant color, by increasing both molecular brightness and FP gene expression level. Natural variation in FP sequences also produces differences in antioxidant capacity. We demonstrate that these FPs are strong antioxidants that can protect live cells against oxidative stress. Finally, based on structural modeling of the responsible amino acids, we propose a model for FP antioxidant function that is driven by molecular surface charge. Together, our findings shed light on the multifaceted functions that can co-occur within a single FP and provide a framework for studying the evolution of fluorescence as it balances spectral and physiological functions in nature
