Artificial Intelligence Helps Manage Global Fisheries

Climate Change, Diversity and Biogeography,

Reporting by Helen Hill for the MIT Darwin Project

Fisheries provide a significant source of protein for over half of the world’s human population, yet the impacts of historical overfishing and climate change challenge the future productivity of the world’s oceans. Traditional fisheries management rests on the assumption that the future will look like the past, however, with advances in AI (artificial intelligence) and burgeoning data resources, scientists have new tools for exploring a greater range of future scenarios, including climate change.  Continue reading Artificial Intelligence Helps Manage Global Fisheries →

A Cellular View of Earth History

Research,

Reporting by Helen Hill for the MIT Darwin Project

For the past several years, Rogier Braakman, a research scientist working in Penny Chisholm’s lab and collaborating with Mick Follows, has been studying how metabolism evolves in ocean microbes. In a new paper, he argues that intrinsic properties of cellular metabolism imposed central constraints on the historical trajectories of biospheric productivity and atmospheric oxygenation.  Continue reading A Cellular View of Earth History →

When Phytoplankton Go Hungry

Macromolecular Modeling, , , ,

by Helen Hill for MIT CBIOMES

The Redfield ratio, the atomic ratio of carbon, nitrogen, and phosphorus (C:N:P) in phytoplankton and deep ocean waters, has often been treated as a constant 106:16:1. A new paper involving several CBIOMES co-authors, among them two from the MIT Darwin Group, presents compelling evidence for what causes this ratio to change within phytoplankton.
