What We Are Reading Today: ‘Magnetic Reconnection’

Author: Masaaki Yamada

Plasmas comprise more than 99 percent of the visible universe; and, wherever plasmas are, magnetic reconnection occurs.

In this common yet incompletely understood physical process, oppositely directed magnetic fields in a plasma meet, break, and then reconnect, converting the huge amounts of energy stored in magnetic fields into kinetic and thermal energy.

In “Magnetic Reconnection,” Masaaki Yamada offers an illuminating synthesis of modern research and advances on this important topic. Magnetic reconnection produces such phenomena as solar flares and the northern lights, and occurs in nuclear fusion devices.

What We Are Reading Today: ‘What We Inherit’

Over the past decade, the field of human genetics has produced an extraordinary range of discoveries—including the refinement of polygenic scores, which use a person’s DNA to estimate their likelihood of developing a trait or disease.

But are these new technologies ready to leave the research lab and be deployed in schools, fertility clinics, and the wider world? “In What We Inherit,” Sam Trejo and Daphne Martschenko offer different perspectives on the societal impact of the rapidly unfolding DNA revolution.
