| Mutualisms—relationships whereby two organisms live in tandem with one another, each providing a service to the other—are among the most interesting and complex relationships in nature. These kinds of relationships are generally considered cooperative interactions, whereby each of the organisms incurs substantial cost in trading services with its partner in order for each of them to gain some... more |

| Fueled both by rapid economic growth and shifting demographics, by 2012, China’s population had exceeded 1.3 Billion, living standards had risen markedly since the 1980s, and nearly half of all Chinese citizens lived in newly built urban areas. As the world watches these massive shifts and debates the nature of the “Chinese Economic Miracle,” an equally fundamental but less visible change ha... more |

| The ribosome, a molecular machine powered by RNA, is responsible for protein synthesis. Ribosomal RNA processing mature and its association with ribosomal protein is the basic process of ribosomal subunit assembly. In eukaryotic cells, this process is conducted in the nucleolus. As a nucleolar complex for small-subunit ribosomal RNA processing, small-subunit (SSU) processome has been extensivel... more |

| Apoptosis resistance is a hurdle for cancer treatment and apoptosis is a critical cellular process required for maintenance of tissue homeostasis. The Caspase family plays a critical role in apoptosis and caspase-8 is an initial caspase for the extrinsic apoptotic pathway. HECTD3, a new E3 ubiquitin ligase, was recently reported to confer breast cancer cells to cisplatin resistance. The possibl... more |

| Traditional accounts of human settlement have traced the development of ancient and sophisticated cultures, like those along the Nile and Yangtze rivers, through the historical and archaeological detritus of their achievements. For older human populations where there are often no records and only scant archeological fragments, linguistic and genetic studies have proved invaluable. Both language... more |
