Electronic circuits that are integrated with your skin Reply

A team of engineers today announced a discovery that could change the world of electronics forever. Called an “epidermal electronic system” (EES), it’s basically an electronic circuit mounted on your skin, designed to stretch, flex, and twist — and to take input from the movements of your body.

EES is a leap forward for wearable technologies, and has potential applications ranging from medical diagnostics to video game control and accelerated wound-healing. Engineers John Rogers and Todd Coleman, who worked on the discovery, tell io9 it’s a huge step towards erasing the divide that separates machine and human.

Nanofiber Regenerates Blood Vessels Reply

A synthetic material may help to repair tissue after a heart attack, and aid transplants.

Regenerating blood vessels is important for combating the aftereffects of a heart attack or peripheral arterial disease, and for ensuring that transplanted organs receive a sufficient supply of blood. Now researchers at Northwestern University have created a nanomaterial that could help the body to grow new blood vessels.

Samuel Stupp and his colleagues developed a liquid that, when injected into patients, forms a matrix of loosely tangled nanofibers. Each of these fibers is covered in microscopic protuberances that mimic vascular endothelial growth factor, or VEGF—a protein that occurs naturally in the body and causes chemical reactions that result in the growth of new blood vessels. By mimicking VEGF, the nanofiber has the same biological effect.

Even as some scientists and engineers develop improved versions of current computing technology, others are looking into drastically different approaches. DNA computing offers the potential of massively parallel calculations with low power consumption and at small sizes. Research in this area has been limited to relatively small systems, but a group from Caltech recently constructed DNA logic gates using over 130 different molecules and used the system to calculate the square roots of numbers. Now, the same group published a paper in Nature that shows an artificial neural network, consisting of four neurons, created using the same DNA circuits.

A New Artificial Lung Can Breathe Regular Air Rather Than Purified Oxygen Reply

The Iron Lung of Yesteryear Cleveland researchers have devised a way to pack all the function of existing artificial lung technology into a more efficient package that is the size of an actual human lung. CDC

Researchers in Cleveland have built an artificial lung that is so efficient it can breathe regular air rather than the pure oxygen required by current artificial lungs. The technology makes possible the idea of a man-made lung that is far more portable–and possibly implantable–for the nearly 200 million people suffering from some degree of lung disease.

Who wants to live forever? Scientist sees aging cured Reply

(Reuters) – If Aubrey de Grey’s predictions are right, the first person who will live to see their 150th birthday has already been born. And the first person to live for 1,000 years could be less than 20 years younger.

A biomedical gerontologist and chief scientist of a foundation dedicated to longevity research, de Grey reckons that within his own lifetime doctors could have all the tools they need to “cure” aging — banishing diseases that come with it and extending life indefinitely.

Artificial womb allows embryos to grow outside the body Reply

Men redundant? Now we don’t need women either

Doctors are developing artificial wombs in which embryos can grow outside a woman’s body. The work has been hailed as a breakthrough in treating the childless.

Scientists have created prototypes made out of cells extracted from women’s bodies. Embryos successfully attached themselves to the walls of these laboratory wombs and began to grow. However, experiments had to be terminated after a few days to comply with in-vitro fertilisation (IVF) regulations.

‘We hope to create complete artificial wombs using these techniques in a few years,’ said Dr Hung-Ching Liu of Cornell University’s Centre for Reproductive Medicine and Infertility. ‘Women with damaged uteruses and wombs will be able to have babies for the first time.’

How to Be Inhuman Reply

Biotechnology holds the promise of some day allowing people to enhance themselves and their children using pharmaceuticals or genetic interventions. This prospect is welcomed by some, but causes a great deal of anxiety in many people: Are there enhancements whose benefits would come at the price of our humanity?

The President’s Council on Bioethics worries that people who choose to use biotech enhancements would somehow lose themselves: The Council’s report “Beyond Therapy” warns “we risk ‘turning into someone else,’ confounding the identity we have acquired through natural gift cultivated by genuinely lived experiences, alone and with others.” Liberal bioethicist George Annas from Boston University is pushing for a global treaty that would ban all inheritable modifications to any person’s genetic makeup. He favors such a treaty because he believes that “species-altering genetic engineering [is] a potential weapon of mass destruction, and [that] makes the unaccountable genetic engineer a potential bioterrorist.”

Abstract

Transhumanism is an emergent philosophical movement which says that humans can and should become more than human through technological enhancements. Contemporary transhumanism has grown out of white, male, affluent, American Internet culture, and its political perspective has generally been a militant version of the libertarianism typical of that culture. Nonetheless transhumanists are becoming more diverse, with some building a broad liberal democratic philosophic foundation in the World Transhumanist Association. A variety of left futurist trends and projects are discussed as a proto-“democratic transhumanism.” The essay also discusses the reaction of transhumanists to a small group of neo-Nazis who have attempted to attach themselves to the transhumanist movement.  For the transhumanist movement to grow and become a serious challenge to their opposites, the bio-Luddites, they will need to distance themselves from their elitist anarcho-capitalist roots and clarify commitments to liberal democratic institutions, values and public policies. By embracing political engagement and the use of government to address equity, safety and efficacy concerns about transhuman technologies, transhumanists are in a better position to attract a larger, broader audience.
