A joint analysis of data from the Planck space mission and the ground-based experiment BICEP2 has found no conclusive evidence of gravitational waves from the birth of our universe, despite earlier reports of a possible detection. The collaboration between the teams has resulted in the most precise knowledge yet of what signals from the ancient gravitational waves should look like, aiding future searches.

NASA successfully launched its first Earth satellite designed to collect global observations of the vital soil moisture hidden just beneath our feet. The Soil Moisture Active Passive (SMAP) observatory now begins a three-year mission that will figuratively scratch below Earth’s surface to expand our understanding of a key component of the Earth system that links the water, energy and carbon cycles driving our living planet.

Seismic investigations from the Qinling-Dabie-Sulu orogenic belt in eastern China suggest that this region was affected by extreme mantle perturbation and crust-mantle interaction during the Mesozoic era. The Qinling-Dabie-Sulu orogenic belt formed through the collision between the North and South China blocks, which produced large-scale destruction of the cratonic lithosphere, accompanied by widespread magmatism and metallogeny.
