Rat Head transplant test leading to human head transplant

Researchers from Harbin Medical University in China and controversial neurosurgeon Sergio Canavero built upon earlier head-grafting experiments to figure out how to avoid damage to the brain tissue during the operation, as well as long-term immune rejection. Previously, scientists have attempted the procedure on dogs and monkeys, which helped to test neural preservation when blood …

Creating spacetime shortcuts with gravitational waveforms without exotic matter for possible FTL communication and FTL travel

A region-delimited gravitational wave field can be constructed, such that a subset of geodesics crossing this region will move faster than nearby geodesics moving entirely inside flat spacetime, along a preferred direction. Null geodesics inside this region will move faster-than-light according to far away observers. The waveform is synthesized from homogeneous plane wave solutions, and …
