Anxiety, depression, and the fear of addiction to pills.
The cure is also the curse.

“Maintenance and discard patterns are a central aspect of projectile point analyses. Unfortunately, while the examination of maintenance and discard patterns for lithic technologies is well advanced, osseous projectile point maintenance and discard analyses remain in their infancy. In the Magdalenian context, a large part of this situation is owing to the fact that the form and proportions of osseous points at the time of initial manufacture have rarely been clearly described, nor particularly well understood, by researchers. This paper focuses on uni- and bilaterally barbed points manufactured from antler and dating to the Late Magdalenian. Through examination of 732 barbed point artefacts recovered from 18 sites located throughout France and Germany, along with engravings on portable art, and a brief consideration of ethnographic data, an updated proposal for the original proportions of these iconic barbed weapon tips can be made. Knowledge of these dimensions is essential if researchers are to reconstruct the reduction of these artefacts through use, maintenance and rejuvenation cycles” (read more/open access).

Prosthesis Transforms Drummer into Three-Armed Cyborg
Prof. Gil Weinberg has already built a band of robotic musicians in his Georgia Tech lab. Now, he’s created a robot that can be attached to amputees, allowing its technology to be embedded into humans. The robotic drumming prosthesis has motors that power two drumsticks. The first stick is controlled both physically by the musicians’ arms and electronically using electromyography (EMG) muscle sensors. The other stick “listens” to the music being played and improvises.
“The second drumstick has a mind of its own,” says Weinberg, founding director of the Georgia Tech Center for Music Technology. “The drummer essentially becomes a cyborg. It’s interesting to see him playing and improvising with part of his arm that he doesn’t totally control.”
