The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.
The patient is an unnamed man in his 20s living in Rome who lost the lower part of his arm following an accident, said Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland.
The wiring of his new bionic hand will be connected to the patient’s nervous system with the hope that the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors.
Dr Micera said that the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves.
This should allow the man to control the hand by his thoughts, as well as receiving sensory signals to his brain from the hand’s sensors. It will effectively provide a fast, bidirectional flow of information between the man’s nervous system and the prosthetic hand.
“This is real progress, real hope for amputees. It will be the first prosthetic that will provide real-time sensory feedback for grasping,” Dr Micera said.
“It is clear that the more sensory feeling an amputee has, the more likely you will get full acceptance of that limb,” he told the American Association for the Advancement of Science meeting in Boston.
“We could be on the cusp of providing new and more effective clinical solutions to amputees in the next year,” he said.
DO YOU PEOPLE EVEN REALIZE HOW AWESOME THIS IS???
TO DO THIS MEANS WE CAN FINALLY STICHT AXONS (LONG PART OF NEURON OR NERVE CELL THAT TRANSPORTS SIGNALS FROM JUNCTIONS BACK TO THE BRAIN) BACK TOGETHER
DO YOU EVEN UNDERSTAND HOW IMPOSSIBLE THAT WAS? TO ALINE THE DAMAGED AXONS BACK TOGETHER WAS IMPOSSIBLE
WITH THIS BRAKE THROUGH YOU COULD EVENTUALLY WORK UP TO GIVING THE ABILITY TO WALK AND MOVE AGAIN TO THOSE WHO CUT THEIR SPINAL CORD IN AN ACCIDENT THIS IS BEAUTIFUL
THIS. IS. AMAZING.
this is so fantastic that I am at a complete loss
bionic body parts that function and feel and act just like real body parts are the first step toward the actual cyber future

Here is a beautiful pairing of a galaxy and an open cluster, right along the plane of the milky way
NGC 6946, (also known as the Fireworks Galaxy, Arp 29, and Caldwell 12), is an intermediate spiral galaxy about 22.5 million light-years away, in the constellations Cepheus and Cygnus. It was discovered by William Herschel on September 9, 1798. NGC 6946 is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane.

As a New Zealander I thought it was high time I posted some archaeology a bit closer to home.
A very important Pacific archaeological site located on the south eastern coast of Raiatea, French Polynesia -the Taputapuatea Marae.
For those of you who don’t know, a marae is a sacred religious gathering place in Polynesian societies. This particular marae was already established by 1000 AD, and was once known as the religious centre and central temple of Eastern Polynesia. Here, people such as priests and navigators would meet to share knowledge and preform sacrifices to the gods.
Member of the Moari iwi Te Rangi Hīroa (anthropologist, politician), upon visiting the site in 1929 was overcome with grief due to the state of the once great marae, and consequently wrote:
I had made my pilgrimage to Taputapu-atea, but the dead could not speak to me. It was sad to the verge of tears. I felt a profound regret, a regret for — I knew not what. Was it for the beating of the temple drums or the shouting of the populace as the king was raised on high? Was it for the human sacrifices of olden times? It was for none of these individually but for something at the back of them all, some living spirit and divine courage that existed in ancient times of which Taputapu-atea was a mute symbol. It was something that we Polynesians have lost and cannot find, something that we yearn for and cannot recreate. The background in which that spirit was engendered has changed beyond recovery. The bleak wind of oblivion had swept over Opoa. Foreign weeds grew over the untended courtyard, and stones had fallen from the sacred altar of Taputapu-atea. The gods had long ago departed.

Fortunately, as of 1994, the archaeological remains of Taputapuatea has been restored, and is currently being pushed to become a recognized United Nations World Heritage site.
