The Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina Right to Try Act of 2017 signed on May 30, 2018 under President Trump has been championed by patient advocacy groups as a victory for individuals with life threatening illnesses willing to undergo experimental treatment. The act is not a novel idea, but rather a nuanced result of the previous attempts to challenge the US Food and Drug Administration's (FDA) authority on drug approval and distribution. Currently, right-to-try programs coexist with an already existing expanded access program run by the FDA.

Article Synopsis
  • Estuaries connect land and ocean, influencing the movement of buoyant materials like plastics and organic matter through complex interactions of river and tidal flows.
  • The study uses simulations and theoretical models to show that tidal currents can retain buoyant particles in estuaries, especially in smaller ones, contrary to the common belief that they mainly flow out to the ocean.
  • Factors such as the width of the estuary and river flow rates significantly impact the retention and export of these materials, helping to predict their behavior in land-sea exchange processes.

In 2016, an unprecedented Pseudo-nitzschia australis bloom in the Gulf of Maine led to the first shellfishery closures due to domoic acid in the region's history. In this paper, potential introduction routes of are explored through observations, a hydrodynamic model, and a Lagrangian particle tracking model. Based on particle tracking experiments, the most likely source of to the Gulf of Maine was the Scotian Shelf.

Worldwide, warming ocean temperatures have contributed to extreme harmful algal bloom events and shifts in phytoplankton species composition. In 2016 in the Gulf of Maine (GOM), an unprecedented bloom led to the first domoic-acid induced shellfishery closures in the region. Potential links between climate change, warming temperatures, and the GOM assemblage, however, remain unexplored.
