### 'Star Trek' Science: How Antimatter Powers The Enterprise [Infographic]

Many of us enjoy the science involved in Star Trek and with the release of Star Trek: Beyond this week I thought it would be fun to talk about one of the things that the movies and shows get right.

### Seminar: Fusion and Plasma Physics

This course uses lectures and discussion to introduce the range of topics relevant to plasma physics and fusion engineering. An introductory discussion of the economic and ecological motivation for the development of fusion power is also presented. Contemporary magnetic confinement schemes, theoretical questions, and engineering considerations are presented by expert guest lecturers. Students enrolled in the course also tour the Plasma Science and Fusion Center experimental facilities.

### Proton Spin Mystery Gains a New Clue | Amazing Science

Physicists long assumed a proton’s spin came from its three constituent quarks. New measurements suggest particles called gluons make a significant contribution. Protons have a constant spin that is an intrinsic particle property like mass or charge. Yet where this spin comes from is such a mystery it’s dubbed the “proton spin crisis.” Initially physicists thought a proton’s spin was the sum of the spins of its three constituent quarks. But a 1987 experiment showed that quarks can account…
