Cyborg gel implant fights diabetes with light
Light can now be used to heal diabetes in mice. By implanting a transparent gel that contains genetically modified light-sensitive cells, researchers have demonstrated a new type of implant that could one day be used to treat disease and monitor toxins in people.
"Light is a great tool to interface with biological systems, but there is a fundamental problem. It gets scattered when it hits tissue, and at depths much thinner than our skin," says lead author Myunghwan Choi of Harvard Medical School in Boston.
Choi and his colleagues designed an implantable gel that could get around this, by guiding light under the mouse's skin. In experiments, the team impregnated the gel with different types of genetically modified cells before implanting it.
To control diabetes, the team shone light into the mouse and at the implanted gel using a fibre optic cable attached to its head. The light triggered cells in the gel to produce a compound that stimulated the secretion of insulin and stabilised blood glucose levels. Separately, the team also showed they could monitor for cadmium poisoning using cells that fluoresced when the mouse was under stress from the toxin.
Cut the cord
Though still at the prototype stage, the ultimate idea is to reduce the need for doctors to perform repeated injections and blood tests to monitor or treat patients.
"The promise is there," agrees Fiorenzo Omenetto, a biotechnologist at Tufts University in Medford, Massachusetts. But he adds it will have to get a little easier to live with than the current implant. "The tough thing here is the presence of a large implant and a fibre sticking out of your head. Not something I'd want if I were diabetic."
Choi's team plans to work on making the gel more user-friendly. For example, he says, "we are thinking of adding a micro-LED with a wireless power receiver [to the gel implant]."
"Genetically modified cells have been engineered for a variety of applications ranging from the treatment of cancer to the prevention of gout," wrote Warren Chan of the University of Toronto, Canada, in a comment piece published alongside the work. "This suggests that the implantable hydrogel could be used for many biological and clinical applications."

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
