I found this [1], which isn't more accessible, but does contain the following in the intro: "... Newton's third law may be violated if we regard it as a open system, with its mechanical energy being injected from microscopic active units." I get that not treating it as a closed system may enable breaking the symmetry of the law. But still no idea how it actually works!
