1甘肃大地湾遗址距今6万年来的考古记录与旱作农业起源显示文摘报道了中国北方早期旱作农业起源地之一的甘肃秦安大地湾遗址Dadiwan06探方的最新发掘成果,根据黄土-古土壤序列、绝对测年(AMS 14C和光释光测年)、气候事件年龄和考古分析,为Dadiwan06探方的地层沉积建立了6.5万年的年代框架.考古材料分析显示,Dadiwan06探方完整记录了石英打制技术制品、细石器技术制品、大地湾一期文化以及仰韶文化陶器制品等分别代表中国北方原始采集狩猎经济、先进采集狩猎经济、早期栽培经济与成熟农业经济的4个不同发展阶段,反映了大地湾遗址距今6.0万年以来由采集狩猎经济逐步向农业经济过渡的持续人类活动历史。张东菊 陈发度 BETTINGER R L BARTON L 吉笃学 MORGAN C 王辉 程晓钟 董广辉 GUILDERSON T P 赵晖 2010科学通报2010,55,10:42
2Mouse embryos cloned from brain tumors显示文摘Cancer cells escape from growth cont rol by accumulating genetic and epig enetic alterations.In rare instances,epigenetic changes alone are oncogenic.Furthermore,a gents that modify DNA methylation or chromatin structure can restore a normal phenotype to cells harboring oncogenic mutations.How ever,it is unclear to what extent epi genetic reprogramming can reverse o ncogenesis.Using somatic nuclear transfer,we show that medul loblastomas arising in Ptc1+/-mice can direct preimplantation develop ment.Additionally,blastocysts derived from medullobl astoma nuclei form postimplantatio n embryos with typical cell layers.T hus,tumor cells can be epigenetically reprogrammed into n ormal cell types.This approach coul d lead to a general strategy for assessing genetic and epigenetic contributions to tumorigenesis.Li L Connelly MC Wetmore C Curran T Morgan JI 2003癌症2003,22,7:11
3Archaeological records of Dadiwan in the past 60 ka and the origin of millet agriculture显示文摘This paper reports the recent excavation of Unit Dadiwan06 at the Dadiwan site in Qin’an County, Gansu.A 65 ka chronological framework is established for Dadiwan06 on the basis of absolute dating (AMS 14C and OSL), stratigraphy, climate change events and archaeology.Artifact distributions reveal patterns of human behavioral variation and adaptation over the past 60 ka, from primitive hunting and gathering to advanced hunting and gathering, to primitive Neolithic agriculture, and finally to advanced Neolithic agriculture.ZHANG DongJu CHEN FaHu BETTINGER R L BARTON L JI DuXue MORGAN C WANG Hui CHENG XiaoZhong DONG GuangHui GUILDERSON T P ZHAO Hui 2010Chinese Science Bulletin2010,55,16:6
