Taking a new tangent to control pesky waves in fusion plasmas

Fusion combines light elements in the form of plasma—"the hot, charged state of matter composed of free electrons and atomic nuclei—"to generate massive amounts of energy. One of the ways that scientists help heat the ...

A star is born: Using lasers to study how star stuff is made

On a typical day at the world's biggest laser, the National Ignition Facility (NIF) in Livermore, California, you can find scientists casually making star-like conditions using 192 high-powered lasers. Stars in the universe ...

Magneto-inertial fusion experiment nears completion

Assembly of the Plasma Liner Experiment (PLX) at Los Alamos National Laboratory is well underway with the installation of 18 of 36 plasma guns in an ambitious approach to achieving controlled nuclear fusion (Figure 1). The ...

Fuel injection helps reduce magnetic island instabilities

Fusion is a non-carbon-based process for energy production, where lighter atoms fuse into heavier ones. Fusion reactors operate by confining a "soup" of charged particles, known as a plasma, within powerful magnetic fields. ...

How to defend the Earth from asteroids

A mere 17-20 meters across, the Chelyabinsk meteor caused extensive ground damage and numerous injuries when it exploded on impact with Earth's atmosphere in February 2013.
