An amputee feels texture in real time: Signals from sensors in an artificial fingertip are converted to neural-like spikes and delivered to nerves in the upper arm. (credit: Ecole polytechnique fédérale de Lausanne)
Amputee Dennis Aabo Sørensen is the first person in the world to recognize texture (smoothness vs. roughness) using an artificial “bionic” fingertip surgically connected to nerves in his upper arm. The experimental system was developed by EPFL (Ecole polytechnique fédérale de Lausanne) and SSSA (Scuola Superiore Sant’Anna).
“The stimulation felt almost like what I would feel with my hand,” says Sørensen. “I felt the texture sensations at the tip of the index finger of my phantom hand.”

Cool beans.
Using a bionic fingertip, an amputee for the first time has been able to feel rough and smooth textures in real-time, as though the fingertip were naturally connected to his hand.
After Luke Skywalker got his hand cut off during a duel with Darth Vader in “Star Wars,” the young Jedi received an artificial hand that helped him both grip and feel again. Scientists worldwide are seeking to make this vision from science fiction a reality with prosthetic limbs that are wired directly into the nervous systems of their recipients.
Researchers experimented with amputee Dennis Aabo Sørensen from Denmark, who damaged his left hand more than a decade ago while playing with fireworks. Doctors immediately amputated the appendage after Sørensen was brought to a hospital. [Bionic Humans: Top 10 Technologies].

In SELF/LESS, a dying old man (Academy Award winner Ben Kingsley) transfers his consciousness to the body of a healthy young man (Ryan Reynolds). If you’re into immortality, that’s pretty good product packaging, no?
But this thought-provoking psychological thriller also raises fundamental and felicitous ethical questions about extending life beyond its natural boundaries. Postulating the moral and ethical issues that surround mortality have long been defining characteristics of many notable stories within the sci-fi genre. In fact, the Mary Shelley’s age-old novel, Frankenstein, while having little to no direct plot overlaps [with SELF/LESS], it is considered by many to be among the first examples of the science fiction genre.
Screenwriters and brothers David and Alex Pastor show the timelessness of society’s fascination with immortality. However, their exploration reflects a rapidly growing deviation from the tale’s derivation as it lies within traditional science fiction. This shift can be defined, on the most basic level as the genre losing it’s implied fictitious base. Sure, while we have yet to clone dinosaurs, many core elements of beloved past sic-fi films are growing well within our reach, if not in our present and every-day lives. From Luke Skywalker’s prosthetic hand in Star Wars Episode V: The Empire Strikes Back (1980) to the Matrix Sentinal’s (1999) of our past science fiction films help define our current reality to Will Smith’s bionic arm in I, Robot.

BMI’s (according to DARPA and David Axe) could begin as early as 2017 on humans. The plan is to use stentrodes. Testing has already proven success on sheep. I personally have concerns in both a health (as the article highlighted prone to blood clots) as well as anything connecting via Wi-Fi or the net with hackers trying to challenge themselves to prove anything is hackable; that before this goes live on a person we make sure that we have a more secure hack-resistant net before someone is injured or in case could injure someone else.
Soldiers could control drones with a thought.

Just Amazing
Ralph Mobbs, a neurosurgeon at the Prince of Wales Hospital in Sydney, made medical history in late 2015 when he successfully replaced two vertebrae with custom made prosthesis. The patient, in his 60s, suffered from Chordoma, a particularly nasty form of cancer that had formed on his top two vertebrae and threatened to cinch off his spinal cord as it grew. That would have left him a quadriplegic. Complicating matters, those top two vertebrae are what allow you to turn and tilt your head, so it’s not like doctors can easily fashion a replacement out of bone grafted from another part of the patient’s body. They have to fit perfectly and that’s where the 3D printers come in.
Mobbs worked with Anatomics, an Australian medical device manufacturer, to craft perfect replicas of the patient’s top two vertebrae out of titanium. This is the first time that these two particular neck bones have been printed and installed. “To be able to get the printed implant that you know will fit perfectly because you’ve already done the operation on a model … It was just a pure delight,” Mobbs told Mashable Australia. “It was as if someone had switched on a light and said ‘crikey, if this isn’t the future, well then I don’t know what is’.”
The surgery itself was no small feat. The 15-hour procedure is fraught with peril as the medical team operates within inches of the top of the spinal cord as well as the brainstem and numerous major arteries. “The surgery that we’re doing today is a particularly complicated and long and difficult surgery. It involves exposure at the top of the neck where the neck and the head meets,” Mobbs told ABC 7.30. “It’s essentially disattaching the patient’s head from his neck and taking the tumour out and reattaching his head back onto his neck.” Thankfully, the surgery was a success. Mobbs was able to remove the tumor and implant the prosthetic.
