On one hand I love Scandal and find it so incredibly fun and dramatic and suspenseful, and on the other hand I have never hated two characters being together more than Olivia and Fitz. I’m a 17 year old boy and their both more hormonal than I am, and it’s dumb

Hyper Matrix, Installation 2012

Hyper-Matrix is a kinetic landscape installation created for the Hyundai Motor Group Exhibition Pavilion in Korea, the 2012 Yeosu EXPO site. The installation consists of a specially made huge steel construction to support thousands of stepper motors that control 320x320mm cubes that project out of the internal facade of the building. The foam cubes are mounted to actuators that move them forward and back by the steppers, creating patterns across the three-sided display.

Bionic hand allows patient to ‘feel’

Dennis Aabo was able to feel what was in his hand via sensors connected to nerves in his upper arm

Scientists have created a bionic hand which allows the amputee to feel lifelike sensations from their fingers.

A Danish man received the hand, which was connected to nerves in his upper arm, following surgery in Italy.

Dennis Aabo, who lost his left hand in a firework accident nearly a decade ago, said the hand was “amazing”.

In laboratory tests he was able to tell the shape and stiffness of objects he picked up, even when blindfolded.

The details were published in the journal Science Translational Medicine.

Implant

An international team carried out the research project, which included robotics experts from Italy, Switzerland and Germany.

"It is the first time that an amputee has had real-time touch sensation from a prosthetic device" said Prof Silvestro Micera from the Ecole Polytechnique Federale de Lausanne and Scuola Superiore Sant’Anna, Pisa.

The scientific advance here was not the hand itself, but the electronics and software that enabled it to give sensory feedback to the brain.

Micera and his team added sensors to the artificial hand which could detect and measure information about touch. Using computer algorithms, the scientists transformed the electrical signals they emitted into an impulse that sensory nerves could interpret.

During an operation in Rome, four electrodes were implanted onto nerves in the patient’s upper arm. These were connected to the artificial sensors in the fingers of the prosthetic hand, so allowing touch and pressure feedback to be sent direct to the brain.

Mr Aabo, 36, a property developer, spent a month doing laboratory tests, firstly to check the electrodes were functioning, and then with these fully connected to the bionic hand.

He said: “The biggest difference was when I grabbed something I could feel what I was doing without having to look. I could use the hand in the dark.

"It was intuitive to use, and incredible to be able to feel whether objects were soft or hard, square or round."

Hero

The bionic hand is still a prototype, and due to safety restrictions imposed on clinical trials, Mr Aabo required a second operation to remove the sensors.

"He is a hero," said Professor Paolo Rossini, neurologist, University Hospital Agostino Gemelli, Rome.

"He gave a month of his life and had two operations to test this device.

"We are all very grateful to him."

Prof Rossini said a lot of pre-training was done involving surgery on pigs, and with human cadavers, to ensure they knew exactly how to attach electrodes to the tiny peripheral nerves in the upper arm.

Another member of the team, Dr Stanisa Raspopovic said: “It was a very exciting moment when after endless hours of testing….Dennis turned to us and said with disbelief, ‘This is magic! I can feel the closing of my missing hand!’”

Those working in the field in the UK were also enthusiastic.

"This is very interesting work, taking research in upper limb prosthetics into the next stage by adding sensory feedback, said Dr Alastair Ritchie, Lecturer in Biomaterials and Bioengineering, University of Nottingham.

"This technology would enable the user to know how firmly they are gripping an object, which is vital for handling fragile objects - imagine picking up an egg without any feeling in your fingers."

The international team is now working on how to miniaturise the technology so that it could be used in the home.

"We must get rid of the external cables and make them fully implantable" said Prof Thomas Stieglitz, University of Frieburg, Germany, whose laboratory created the ultra-thin implantable electrodes.

Recently, scientists in Cleveland, Ohio released a video of a patient using the fingers of a prosthetic hand to pull the stalks from cherries while blindfolded. But the research has not yet been published in a peer-reviewed journal.

There is no precise timetable, but scientists think it could be a decade before a sensory feedback bionic hand is commercially available.

And they believe it may pave the way for more realistic prosthetic devices in the future which can detect texture and temperature.

'Bring it on'

But it will undoubtedly be very expensive, well beyond the means of most patients. And artificial hands still lack the precision and dexterity of the real thing.

The super-functioning bionic hand of science fiction films remains the stuff of fiction.

Nonetheless, Dennis Aabo, who now has his old prosthesis back, is ready to swap it for the bionic hand in any future trial.

"If they offer it to me, I will say bring it on, I’m ready."

In 1979, when the minimum wage was $2.90, a hard-working student with a minimum-wage job could earn enough in one day (8.44 hours) to pay for one academic credit hour. If a standard course load for one semester consisted of maybe 12 credit hours, the semester’s tuition could be covered by just over two weeks of full-time minimum wage work—or a month of part-time work. A summer spent scooping ice cream or flipping burgers could pay for an MSU education. The cost of an MSU credit hour has multiplied since 1979. So has the federal minimum wage. But today, it takes 60 hours of minimum-wage work to pay off a single credit hour, which was priced at $428.75 for the fall semester.
