Summary:
Scientists at MIT discovered that chaotic laser light can spontaneously form
a highly focused beam instead of scatteringrCoif the conditions are just right.
This rCLpencil beamrCY enabled them to image the blood-brain barrier in 3D at speeds
25 times faster than existing techniques.
The method also lets researchers watch how drugs move into brain cells in real time.
It could dramatically accelerate the development of treatments for neurological diseases.
