Couldn't the aeronautical capabilities of an unpiloted aircraft have a significantly higher ceiling if the design doesn't need to accommodate for limiting g-forces on a human?
Not by much. Building airframes that can handle higher G forces than a human comes at a huge weight penalty which impacts cost, range, and payload. Plus, it becomes really tough to avoid compressor stall when the flight envelope gets into high AoA plus high speed. The engineers end up having to do funky things with the inlet that increase drag and radar signature.
KrakenSDR would do a good job of this, they combine five RTLSDR into a coherent array. The top end of their tuning range is 1766 MHz which would include the 1575 MHz of the GPS L1 signal.
The little five antenna array can even attach on the roof of a car for a handy ground plane. Prob not a good idea to drive with it out there tho.
There is also the valproic acid study where the window of the critical period appeared to be reopened in a two week study of 24 adult individuals.
Valproic acid is used as an anticonvulsant and mood stabilizer, thought to enhance brain plasticity, and (unfortunately) can cause big problems in livers.
When there is greater understanding of the pathways affected there could be safer options for re-entering the critical period after the window has closed.
