New artificial, bionic hands start to get real feelings

Simple tasks, like plucking the stem off a cherry, are still monumental challenges for artificial hands. With a bill of materials perhaps a few hundred components long, it is not surprising that their functionality is low compared with one assembled from trillions of components. A new prosthetic bionic hand, designed and built by researchers at Case Western University is now capable of using measurements from 20 sensor points to control the grip force of its digits. Incredibly, the sensor data is linked directly to the sensory nerves in the patient’s forearm. The control for the grip closure is then extracted myoelectrically from the normal biological return loop to the muscles in the forearm.

Hands-free devices like Google Glass can be really transformative when the hands they free are those of a surgeon. And leading hospitals, including Stanford and the University of California at San Francisco, are beginning to use Glass in the operating room.

In October, UCSF’s Pierre Theodore, a cardiothoracic surgeon, became the first doctor in the United States to obtain Institutional Review Board approval to use the device to assist him during surgery. Theodore pre-loads onto Glass the scans of images of the patient taken just before surgery and consults them during the operation.

How 3D Printers Are Cranking Out Eyes, Bones, and Blood Vessels

At the dawn of rapid prototyping, a common predication was that 3D printing would transform manufacturing, spurring a consumer revolution that would put a printer in every home. That hasn’t quite happened—-and like so many emerging technologies, rapid prototyping has found its foothold in a surprisingly different field: Medicine.

The following studies and projects represent some of the most fascinating examples of “bioprinting,” or using a computer-controlled machine to assemble biological matter using organic inks and super-tough thermoplastics. They range from reconstructing major sections of skull to printing scaffolding upon which stem cells can grow into new bones. More below—and look out for more 3D printing week content over the next few days.

Hair, bone and soft tissue regrown in mice by enhancing cell metabolism

Anyone who has left youth behind them knows that bumps and scrapes don’t heal as fast as they used to. But that could change with researchers at the Stem Cell Program at Boston Children’s Hospital finding a way to regrow hair, cartilage, bone, skin and other soft tissues in a mouse by reactivating a dormant gene called Lin28a. The discovery could lead to new treatments that provide adults with the regenerative powers they possessed when very young.

Lin28 is a gene that is abundant in embryonic stem cells and which functions in all organisms. It is thought to regulate the self-renewal of stem cells with the researchers finding that by promoting the production of certain enzymes in mitochondria, it enhances the metabolism of these cellular power plants that found in most of the cells of living organisms. In this way, Lin28 helps generate the energy needed to stimulate the growth of new tissues.

Defying Aging: The ELPIs Foundation for Indefinite Lifespans

Posted by in categories: biotech/medical, evolution, life extension

In is now quite clear that aging is not a simple phenomenon and it will not be overcome by using simple approaches. We need to increase the complexity and sophistication of our efforts in order to be in a better position to develop strategies against it. For this reason, I set up the ELPIS Foundation for Indefinite Lifespans (www.elpisfil.org) which is a scientific research organisation aiming to study aging from a complex evolutionary perspective.

The foundation’s research methodology is based mainly upon the ELPIS hypothesis (www.elpistheory.info). The initials stand for ‘Extreme Lifespans through Perpetual –equalising Interventions’. I developed this hypothesis in 2010 whilst trying to examine the reason behind the presence of aging. It was clear that aging is not an essential component of our evolutionary development, and if we find ways to study why nature has developed it, we may then be able to eradicate it. Currently, the chances of us dying from aging are heavily against us. By developing suitable interventions, we may be able to equalise the odds against us dying (i.e. remove aging as a cause of death).

Our method is different from most existing approaches aiming to eliminate aging. We are mainly interested in the ‘connection-approach’ and not so much in the ‘component-approach’. We believe that it is important to study how the different components of the organism are interconnected and regulated, rather than just repair the individual components. It is the ‘why aging happens’ rather than the ‘how it happens’ that interests us most. In order to make this clear let me mention an analogy with poliomyelitis.

Polio
*How it happens? There is inflammation and necrosis leading to damage of motor neurons and, ultimately, muscle weakness and paralysis
* Why it happens? Because the poliovirus causes it

Do unemployed people age faster?

Posted by in categories: biological, biotech/medical, economics, homo sapiens, life extension, science

By Avi Roy, University of Buckingham and Anders Sandberg, University of Oxford

Men who are unemployed for more than two years show signs of faster ageing in their DNA, according to a study published today in the journal PLOS ONE.

Researchers at the University of Oulu, Finland and Imperial College, London arrived at this conclusion by studying blood samples collected from 5,620 men and women born in Northern Finland in 1966. The researchers measured the lengths of telomeres in their white blood cells, and compared them with the participants’ employment history for the prior three years, and found that extended unemployment (more than 500 days in three years) was associated with shorter telomere length.

Telomeres are repetitive DNA sequences at the ends of chromosomes, which protect the chromosomes from degrading. With every cell division, it appears that these telomeres get shorter. And the result of each shortening is that these cells degrade and age.

Grindhouse Wetware — Support Open Source Transhumanism

Posted by in categories: biotech/medical, business, open source

Grindhouse Wetware is a collective of makers and engineers founded on a basic principle – human augmentation should be accessible and open. All of our devices are built off of open source platforms. This allows our users to peer into the hardware and code of their implanted device and truly control their augmented experience. Grindhouse Wetware’s devices are tailored to Makers and DIY Transhumanists that want to build a specific, unique augmentation. What do you want to be?

After three years of development, our flagship project – Circadia, is in its final stages. Grindhouse Wetware is seeking financial support from individuals or organizations to facilitate the production of this device.

The Circadia implant records bio-medical data and transmits it to the user’s phone via bluetooth. Instead of a snapshot of the user’s state of health, the Circadia records the up-to-date status of the their well being. Grindhouse Wetware firmly believes that once an implant has been installed in an individual, it becomes a part of their person. As such, the data generated by the Circadia belongs to the user.

If you are interested in supporting Grindhouse Wetware and the Circadia implant, please contact me at [email protected] or 631−715−9209
