Physicists Measure Force that Makes Antimatter Stick together[Nov 06, 2015]

Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force between antiprotons is attractive and strong. The experiments were conducted at the Relativistic Heavy Ion Collider (RHIC).

Teeth Reveal Modern Humans in Asia 80,000 Years Ago[Oct 16, 2015]

Tooth fossils found in a county in central China's Hunan Province indicate the early form of modern homo sapiens appeared in the region more than 80,000 years ago. The 47 fossils, found in Daoxian county, date back from 80,000 to 120,000 years and are believed to be the oldest remains of a completely modern form scientists have known in the east Asia region, the study's leading scientists said on Thursday.

Scientists Discover First Binary Black Hole[Sep 06, 2015]

Scientists have discovered clear proof of two supermassive black holes orbiting each other within the same galaxy at the nearest quasar Markarian 231 (Mrk 231). This is the first proven case of supermassive binary black holes (BBHs), according to research published in the Astrophysical Journal, Volume 809, Number 2.

X-ray Laser Sheds Light on Structure of Important Biomolecular Complex[Jul 22, 2015]

Using one of the brightest X-ray lasers in the world, a joint research group involving 28 laboratories and led by Dr. H. Eric XU, a professor from the Shanghai Institute of Materia Medica, has determined the structure of a molecular complex that is responsible for regulating vital physiological functions. The new findings provide scientists with a new model for major pharmacological drug targets.

Chinese Biologists Find Key Process to Obtain Adult Stem Cells[May 20, 2015]

The Chinese Academy of Sciences (CAS) announced scientists have discovered a new method for reprogramming and obtaining induced pluripotent stem cells (iPS cells), or stem cells derived from adult cells. The latest research by stem-cell biologist Pei Duanqing and his team revealed autophagy, a process in generating iPS, does not play a vital role in reprogramming. Previously, it was believed it did.

China's "most advanced" Research Ship Ready to Serve[Apr 27, 2015]

China's most advanced, independently-made marine science expedition vessel is ready for service after passing official certification Friday, according to the Chinese Academy of Sciences (CAS). Development of "Kexue" (science), a 4,700-tonne vessel capable of conducting deep and open sea exploration and research, began in 2007. said a CAS statement.
