China plans super collider
For decades, Europe and the United States have led the way when it comes to high-energy particle colliders. But a proposal by China that is quietly gathering momentum has raised the possibility that the country could soon position itself at the forefront of particle physics.
Scientists at the Institute of High Energy Physics (IHEP) in Beijing, working with international collaborators, are planning to build a ‘Higgs factory’ by 2028 — a 52-kilometre underground ring that would smash together electrons and positrons. Collisions of these fundamental particles would allow the Higgs boson to be studied with greater precision than at the much smaller Large Hadron Collider (LHC) at CERN, Europe’s particle-physics laboratory near Geneva, Switzerland.
Physicists say that the proposed US$3-billion machine is within technological grasp and is considered conservative in scope and cost. But China hopes that it would also be a stepping stone to a next-generation collider — a super proton–proton collider — in the same tunnel.

The Five-hundred meter Aperture Spherical Telescope, known by the acronym FAST, is a radio telescope currently under construction in a remote area of southwest China's Guizhou province. It will be the world's largest and most sensitive radio telescope when completed by 2016. And this afternoon, the first of the main cable net, composed of 9,000 cables, will be installed at the facility.
It's the size of 30 football fields. The world's largest telescope stands in Dawodang, Pingtang County, a region featuring typical Karst depressions.
