Observation of directional change of core field inside flux ropes within one reconnection diffusion region in the Earth’s magnetotail
Two consecutive magnetic flux ropes, separated by less than 30 s (Δt < 30 s), are observed within one magnetic reconnection diffusion region without strong guide field in the Earth’s magnetotail by Cluster multi-...

Same impact momentum causes different degrees of spinal cord injury
The weight-drop impact is widely used in making animal model of spinal cord injury (SCI). But there has not yet been an appropriate unit for the quantification of the impact. In this study, we compared the deg...

Metformin targets liver tumor-initiating cells through the PI3K/Akt/mTOR survival pathway
Liver tumor-initiating cells (T-ICs) are thought to be inherently resistant to the cytotoxic effects of chemotherapy, and can self-renewal and maintain tumor-initiating potential. Therefore, effective anticanc...
