Neurons

Reconnecting severed nerves is no small matter. But electrical engineers at the University of Alberta have demonstrated a method for doing this. Quoting directly: “To conduct the study, two neurons, put in a special solution that prevents them from sticking together, were brought into contact with each other. Femtosecond laser pulses—each ultrashort pulse occurring every 10-15 seconds—were delivered to the meeting point of the two cells. Although the outside layer of the cells was partially compromised, the inside of that protective layer remained intact. As a result, the two cells established solid bonds forming a common membrane at the targeted area.”   MORE
