For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. (more…)

Educators and policymakers have spent decades trying to recruit and retain more underrepresented minority students into the science, technology, engineering, and math (STEM) pipeline. A new analysis of disappointing results in the pipeline’s output leads two Brown University biologists to suggest measures to help the flow overcome an apparent gravity.
PROVIDENCE, R.I. [Brown University] — Decades of effort to increase the number of minority students entering the metaphorical science, technology, engineering, and math (STEM) pipeline, haven’t changed this fact: Traditionally underrepresented groups remain underrepresented. In a new paper in the journal BioScience, two Brown University biologists analyze the pipeline’s flawed flow and propose four research-based ideas to ensure that more students emerge from the far end with Ph.D.s and STEM careers.
