在一项新的研究中，来自北京生命科学研究所等研究机构的研究人员对具有再生能力的哺乳动物（兔子、山羊和非洲刺鼠）与不具备再生能力的小鼠和大鼠进行了比较基因组分析。 该全新的手性控制模式代表了催化剂设计领域的一次重要突破，为解决不对称催化 ...

Ever since cloning produced Dolly the sheep, scientists have copied a slew of mammals ranging from dogs to ponies. Primates, however, have been elusive -- until now. Chinese researchers have ...

Will there ever be another horse like Barbaro? Maybe so, if it were up to cloning researcher Katrin Hinrichs. Theoretically, you could take a tissue sample from the now-dead racehorse, culture some ...

PITTSBURGH (KDKA) - More than 20 years ago, in July 1996, Dolly the sheep was born at a research facility in Scotland. While scientists worked to clone animals for decades, Dolly was the first mammal ...

Yes, even a scientist is entitled to the belief that human life (and the human soul) begins at conception, and that cloning is a morally reprehensible intervention in that Divine scheme. The belief in ...

This spring, South Korean scientists led by Hwang Woo Suk published a paper in the journal Science that showed they had used cloning techniques to create 11 embryonic stem cell lines tailored to match ...
