Musk's Neuralink says second trial implant went well, no thread retraction issue

Elon Musk's brain technology startup Neuralink said its implant, designed to allow paralyzed patients to use digital devices by thinking alone, is working well in a second trial patient.
The company said the patient, identified as Alex, did not face issues of "thread retraction", unlike Noland Arbaugh, Neuralink's first patient who received the implant in January.
