• Neuralink has gotten the FDA go-ahead for a second implant, The Wall Street Journal reports.
• This time, it's implanting the wires a few millimeters deeper to prevent retraction, the report says.
• Neuralink's first patient lost some function in his device but said it had since greatly improved.

Neuralink has apparently gotten the go-ahead to implant its device into a second patient — and settled on a fix for the error that plagued its inaugural trial.
