Johnny Matheny demonstrates how a modular prosthetic limb works during DARPA Demo Day 2016 at the Pentagon, May 11, 2016. Matheny is a test subject with the Johns Hopkins Applied Physics Lab8.
For a long time, biohackers have been playing with magnets by embedding then under their skin as a novelty extra-sensation. I, personally, don’t see the point, but morphological, taxonomic, and cladic freedom are at work so I celebrate their actions.
Our skin’s ability to perceive pressure, heat, cold, and vibration is a critical safety function that most people take for granted. But burn victims, those with prosthetic limbs, and others who have lost skin sensitivity for one reason or another, can’t take it for granted, and often injure themselves unintentionally.
Chemists Islam Mosa from UConn, and James Rusling from UConn and UConn Health, along with University of Toronto engineer Abdelsalam Ahmed, wanted to create a sensor that can mimic the sensing properties of skin. Such a sensor would need to be able to detect pressure, temperature, and vibration. But perhaps it could do other things too, the researchers thought.
“It would be very cool if it had abilities human skin does not; for example, the ability to detect magnetic fields, sound waves, and abnormal behaviors,” said Mosa.
A movie montage for modern artificial intelligence might show a computer playing millions of games of chess or Go against itself to learn how to win. Now, researchers are exploring how the reinforcement learning technique that helped DeepMind’s AlphaZero conquer chess and Go could tackle an even more complex task—training a robotic knee to help amputees walk smoothly.
Computer algorithms help prosthetics wearers walk within minutes rather than requiring hours of training.
Here is another advanced prosthetic device that can make life easier for amputees. BrainRobotics’ EMG Prosthetic Hand features a modular mechanical design. It comes with 8 signal detection channels for precise EMG readings. An advanced machine learning algorithm is used to allow users to intuitively control this robotic prosthesis.

(Hoboken, N.J. — Nov. 7, 2018) — In their latest feat of engineering, researchers at Stevens Institute of Technology have taken an ordinary white button mushroom from a grocery store and made it bionic, supercharging it with 3D-printed clusters of cyanobacteria that generate electricity and swirls of graphene nanoribbons that can collect the current.
The work, reported in the Nov. 7 issue of Nano Letters, may sound like something straight out of Alice in Wonderland, but the hybrids are part of a broader effort to better improve our understanding of cells biological machinery and how to use those intricate molecular gears and levers to fabricate new technologies and useful systems for defense, healthcare and the environment.
“In this case, our system – this bionic mushroom — produces electricity,” said Manu Mannoor, an assistant professor of mechanical engineering at Stevens. “By integrating cyanobacteria that can produce electricity, with nanoscale materials capable of collecting the current, we were able to better access the unique properties of both, augment them, and create an entirely new functional bionic system.”

On the second balmy day of the year in New York, Neil Harbisson, a Catalan artist, musician, and self-professed “cyborg,” walked into a café in the Nolita district of Manhattan. The actor Gabriel Byrne was sitting at a table in the corner. Harbisson approached. “May I do a sound portrait of you? It will just take one minute. For nine years, I’ve been listening to colors,” he explained.
Byrne eyed his questioner from under raised eyebrows. On a slight frame, the 30-year-old Harbisson wore a white T-shirt, deep-pink jeans and black-and-white showman’s brogues. His face was angular, with an aquiline nose and a chin smudged with grown-out stubble. A small plastic oval floated in front of his forehead, attached to the end of a flexible stem that reached around from the back of his head and over a sandy pageboy mop, like the light on the head of an angler fish. This “eyeborg,” as Harbisson calls it, converts light into audible sound, with a pitch that varies according to the color of the light.
Though it resembles a coral, root system, or some other kind of growth, the above photo actually depicts a six-inch-wide blood clot in the near-perfect form of the right bronchial tree of a human lung, the Atlantic reported on Thursday. Even more uncomfortable is the revelation that it was not removed by medical staff, but in fact coughed up by a patient who was suffering from heart failure.
The photo was released in late November as part of the New England Journal of Medicine’s Images in Clinical Medicine series. University of California at San Francisco doctors Gavitt A. Woodard and Georg M. Wieselthaler wrote that it came from their patient, a 36-year-old man who had long struggled with chronic heart failure. The patient reportedly had a medical history including “heart failure with an ejection fraction of 20%, bioprosthetic aortic-valve replacement for bicuspid aortic stenosis, endovascular stenting of an aortic aneurysm, and placement of a permanent pacemaker for complete heart block.” When the patient was admitted to the hospital’s intensive care unit, they hooked him up to a pump designed to help circulate blood throughout the body:
An Impella ventricular assist device was placed for management of acute heart failure, and a continuous heparin infusion was initiated for systemic anticoagulation. During the next week, the patient had episodes of small-volume hemoptysis, increasing respiratory distress, and increasing use of supplemental oxygen (up to 20 liters delivered through a high-flow nasal cannula). During an extreme bout of coughing, the patient spontaneously expectorated an intact cast of the right bronchial tree.
