Messenger RNA can travel between different types of stem cells through tunnel-like structures, as revealed by a new study. By studying interactions between mouse and human stem cells, they discovered that this RNA transfer can reprogram human cells to an earlier developmental state. This groundbreaking finding not only sheds light on an underexplored form of cellular communication but also suggests promising applications in regenerative medicine without using artificial genetic modifications or external chemicals.

A new study has revealed that African Elephants have an extraordinary ability to meet their colossal food requirements as efficiently as possible. Data from over 150 elephants demonstrated that these giants plan their journeys based on energy costs and resource availability. The findings – published today (26 March) in the Journal of Animal Ecology– could provide crucial information to help protect these iconic animals and their habitats.
