Using new and published marine fossil radiocarbon (14C) measurements, a tracer uniquely sensitive to circulation and air-sea gas exchange, we establish several benchmarks for Atlantic, Southern, and Pacific deep-sea circula- tion and ventilation since the last ice age. We find the most 14C-depleted water in glacial Pacific bottom depths, rather ...

Symmetry, topology, and the many faces of condensed matterSymmetry is powerful principle in physics, allowing us to make exact statements even in regimes where controlled calculations are challenging or impossible. Thus, understanding the ways in which different types of symmetries can constrain phases of matter is an important component of understanding what nature is capable of. Â In this ...
Increasingly severe and frequent floods and droughts inevitably spur calls for higher levees, bigger drains, and longer aqueducts. But as we grapple with extreme weather, a hard truth is emerging: our development, including concrete infrastructure designed to control water, is actually exacerbating our problems. Because sooner or later, water always ...

 Every human's previous encounters with reality are the source of internal mental predictions that help to shape future experiences. So, seeing the "real world" (or hearing sounds, or feeling pain, or ...) involves a personal, ideosyncratic filter/kaleidoscope. This prediction-based theory of mind is quite hopeful. More than a facile version ...

Observations of turbulent dissipation in the coastal ocean from an autonomous underwater vehicleThe location and intensity of mixing in the world’s oceans is a fundamental topic of modern oceanography, yet the range of dynamical scales in oceanic flows has challenged efforts to quantify when and where dissipation of mechanical energy occurs. Such knowledge is essential to global climate science and prediction. Although global ocean models can resolve ...
