Earth Core is Melting and Freezing

New findings could help us understand how the inner and outer core react as a geodynamo which create magnetic field. Dr Jon Mound from University of Leeds says that it's still hard to tell the origin of magnetic field as we can't go collect sample so we have to rely on surface measurement and computer models to tell us what's happening in the core.

Victims of third-degree burns and other traumatic injuries endure pain, disfigurement, invasive surgeries and a long time waiting for skin to grow back. Improved tissue grafts designed by Cornell scientists that promote vascular growth could hasten healing, encourage healthy skin to invade the wounded area and reduce the need for surgeries.
