A 14,400-year-old wolf puppy’s last meal is shedding light on the last days of one of the Ice Age’s most iconic megafauna ...

The work marks the first time an Ice Age animal’s complete genome has been recovered from tissue preserved inside another ...

An unusual DNA source shows woolly rhinos did not slowly decline genetically, pointing instead to rapid climate warming.

The digested meat from the wolf pup’s last meal, which took place 14,400 years ago, contained enough woolly rhino DNA to ...

This important study, which tackles the challenge of analyzing genome integrity and instability in unicellular pathogens by introducing a novel single-cell genomics approach, presents compelling ...

Towards the end of the last ice age, an ancient wolf feasted on a young woolly rhinoceros (Coelodonta antiquitatis). When the ...

A research team led by Zhiping Weng, Ph.D., and Jill Moore, Ph.D."18, at UMass Chan Medical School, has nearly tripled the ...

The woolly rhino, Coelodonta antiquitatis, would have been an impressive sight to the ancient people who painted images of ...

研究这个蛋白很有趣，因为它控制着细菌中大量基因的表达，当病毒或其他微生物将外源DNA插入结核菌基因组时，这些“外来户”可能扰乱细菌的正常运作。因此，细菌必须识别并抑制这些基因的表达。传统观点认为，蛋白质通过结合到DNA的特定序列上，像锁和钥匙一样精确配对，从而阻止细胞机器“读取”DNA；但Lsr2采用了完全不同的策略。研究人员发现，Lsr2会结合到富含腺嘌呤（A）和胸腺嘧啶（T）的大片DNA区域。

Researchers discovered how the Lsr2 protein silences foreign DNA in tuberculosis bacteria. By forming protein condensates on ...

Ancient DNA is turning human evolution into a crime scene reconstruction, and one of the prime suspects is a herpesvirus that ...
