Science: The youthful field of astroparticle physics--the study of the universe via the cosmic rays, gamma rays, gravity waves, and neutrinos that rain down on Earth--has a growing appetite for infrastructure funding. Last week, a body representing astroparticle physicists across Europe released the first draft of a wish list of facilities. “We’re trying to decide which large infrastructures can be funded in the next 10 years,” says Stavros Katsanevas of France’s National Institute for Nuclear and Particle Physics.
