Parallel to this trend, we are seeing advancements in neuroscience being made from global projects like the BRAIN initiative in the U.S. and its counterpart in Europe, the Human Brain Project. These projects seek to decode the human brain and tailor it for “treatments,” as well as to enable the realization of full brain-computer-interface technology. The pace of these developments has increased toward the dizzying, such as a “living” transistor that uses DNA merged with graphene, the advent of quantum computing and nanocomputing, the creation of avatars, DNA nanobots, and a range of neuro applications that are beginning to transform our fundamental relationship with the “real” world.
One respected scientific journal announced earlier this year that the era of cyborgs indeed has begun, as an array of medical applications are merging us with machines and computer systems. This is also happening in tandem with augmented reality applications that have entered the consumer space.
The latest press release states emphatically that we are “On the Frontiers of Cyborg Science.” Once again, only the potential benefits are noted, but the funding for the research cited comes from the U.S. Department of Defense, the National Institutes of Health and the U.S. Air Force. As you read the full chronicle of the developments to date, how do you believe this science will be used? With funding sources such as these, can you imagine some negative consequences?

Press release: “On the frontiers of cyborg science”
No longer just fantastical fodder for sci-fi buffs, cyborg technology is bringing us tangible progress toward real-life electronic skin, prosthetics and ultraflexible circuits. Now taking this human-machine concept to an unprecedented level, pioneering scientists are working on the seamless marriage between electronics and brain signaling with the potential to transform our understanding of how the brain works — and how to treat its most devastating diseases.
Their presentation is taking place at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society. The meeting features nearly 12,000 presentations on a wide range of science topics and is being held here through Thursday.
“By focusing on the nanoelectronic connections between cells, we can do things no one has done before,” says Charles M. Lieber, Ph.D. “We’re really going into a new size regime for not only the device that records or stimulates cellular activity, but also for the whole circuit. We can make it really look and behave like smart, soft biological material, and integrate it with cells and cellular networks at the whole-tissue level. This could get around a lot of serious health problems in neurodegenerative diseases in the future.”
These disorders, such as Parkinson’s, that involve malfunctioning nerve cells can lead to difficulty with the most mundane and essential movements that most of us take for granted: walking, talking, eating and swallowing.
Scientists are working furiously to get to the bottom of neurological disorders. But they involve the body’s most complex organ — the brain — which is largely inaccessible to detailed, real-time scrutiny. This inability to see what’s happening in the body’s command center hinders the development of effective treatments for diseases that stem from it.
By using nanoelectronics, it could become possible for scientists to peer for the first time inside cells, see what’s going wrong in real time and ideally set them on a functional path again.
For the past several years, Lieber has been working to dramatically shrink cyborg science to a level that’s thousands of times smaller and more flexible than other bioelectronic research efforts. His team has made ultrathin nanowires that can monitor and influence what goes on inside cells. Using these wires, they have built ultraflexible, 3-D mesh scaffolding with hundreds of addressable electronic units, and they have grown living tissue on it. They have also developed the tiniest electronic probe ever that can record even the fastest signaling between cells.
Rapid-fire cell signaling controls all of the body’s movements, including breathing and swallowing, which are affected in some neurodegenerative diseases. And it’s at this level where the promise of Lieber’s most recent work enters the picture.
In one of the lab’s latest directions, Lieber’s team is figuring out how to inject their tiny, ultraflexible electronics into the brain and allow them to become fully integrated with the existing biological web of neurons. They’re currently in the early stages of the project and are working with rat models.
“It’s hard to say where this work will take us,” he says. “But in the end, I believe our unique approach will take us on a path to do something really revolutionary.”
