New Scientist: According to a new report from the United Nations University and INTERPOL, in 2012 only 35% of Europe's electronic waste was properly disposed of. Of the remainder, 1.3 million tons were stolen, including functional computer components and precious metals worth some €1.7 billion ($1.9 billion). Another 4.7 million tons were improperly disposed of or illegally traded. Improper disposal of electronics poses a threat to the environment and to public health because of the variety of toxic materials—such as lead, cadmium, and mercury—they contain.
Ars Technica: Some exoplanetary systems consist of planets orbiting stars that have distant binary companions. According to new simulations of such systems, if a planet's orbital precession around its star falls into resonance with the orbital period of the binary, the resulting gravitational forces could lead to drastic changes in the planet's orbit. In particular, the planet's orbit could become highly elliptical or be forced into a different plane from that of the other planets in the system. In extreme cases, the planet could be ejected from the system or forced to collide with another planet or with one of the stars.
