研究人员已经设计出世界上首批能够利用光能的酵母细胞之一，这扩大了我们对这一特性进化的理解，并为生物燃料生产和细胞衰老的进步铺平了道路。

研究人员将一只1.4万年前的长毛猛犸象的旅行与阿拉斯加已知最古老的人类定居点联系起来，为这一标志性物种与一些最早穿越白令大陆桥的人之间的关系提供了线索。同位素数据，以及该遗址其他猛犸象的DNA和考古证据表明，早期阿拉斯加人的定居点可能与猛犸象聚集的区域重叠。新一期《科学进展》杂志重点报道了这些发现，证明猛犸象和早期狩猎采集者在该地区共享栖息地。长毛猛犸象的长期可预测存在会吸引人类到该地区。

一个多世纪以来，科学家们已经了解了植物细胞中的一种特殊细胞器。然而，科学家们直到现在才发现细胞器在衰老中的关键作用。

新的理论研究提出，动物的大小随着时间的推移取决于两个关键的生态因素。

一项为期七年的旗舰研究现已发表，该研究探讨了环境压力如何影响不同的生态过程，从而塑造地下水中微生物群落的组成和结构。

Scattering sunlight-reflecting particles in the atmosphere could slow rapid melting in West Antarctica and reduce the risk of catastrophic sea-level rise, according to a study led by Indiana University researchers.

A team led by scientists at Rensselaer Polytechnic Institute has 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in

A new study has cast doubt on claims that Homo naledi, a small-brained hominin dating to between 335-241,000 years ago, deliberately buried their dead and produced rock art in Rising Star Cave, South Africa.

A team of researchers from Nanyang Technological University, Singapore (NTU Singapore) has developed a computer program that creates realistic videos that reflect the facial expressions and head movements of the person speaking, only requiring an audio cl

The fascinating world of bacteria that live as symbionts or parasites in animal hosts often remains a mystery to researchers. Kiel University (CAU) and the Max Planck Institute for Marine Microbiology in Bremen are contributing to solving this puzzle with

A compound -- one of 27 million screened in a library of potential new drugs -- reversed four types of chronic pain in animal studies, according to new research led by NYU College of Dentistry's Pain Research Center and published in the Proceedings o
