Mice severely disabled by a condition similar to multiple sclerosis (MS) could walk less than two weeks following treatment with human stem cells. The finding, which uncovers new avenues for treating MS, will be published online on May 15, 2014, in the journal Stem Cell Reports.

When scientists transplanted human stem cells into MS mice, they expected no benefit from the treatment. They thought the cells would be rejected, much like rejection of an organ transplant.

Instead, the experiment yielded spectacular results.

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.

The team used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that is similar to bone and makes up the bulk of teeth. What’s more, they outlined the precise molecular mechanism involved, and demonstrated its prowess using multiple laboratory and animal models.

Mind uploading won’t lead to immortality

Posted by in categories: bionic, biotech/medical, evolution, futurism, human trajectories, life extension, neuroscience, philosophy, posthumanism, robotics/AI, singularity, transhumanism

Uploading the content of one’s mind, including one’s personality, memories and emotions, into a computer may one day be possible, but it won’t transfer our biological consciousness and won’t make us immortal.

Uploading one’s mind into a computer, a concept popularized by the 2014 movie Transcendence starring Johnny Depp, is likely to become at least partially possible, but won’t lead to immortality. Major objections have been raised regarding the feasibility of mind uploading. Even if we could surpass every technical obstacle and successfully copy the totality of one’s mind, emotions, memories, personality and intellect into a machine, that would be just that: a copy, which itself can be copied again and again on various computers.

THE DILEMMA OF SPLIT CONSCIOUSNESS

Neuroscientists have not yet been able to explain what consciousness is, or how it works at a neurological level. Once they do, it is might be possible to reproduce consciousness in artificial intelligence. If that proves feasible, then it should in theory be possible to replicate our consciousness on computers too. Or is that jumpig to conclusions ?

Keeping your attention

A growing body of research suggests noninvasive brain stimulation, such as transcranial direct current stimulation (tDCS), may improve specific cognitive skills in healthy subjects. Put another way, a small intermittent shock to your brain might keep your attention from eroding throughout the day.

It’s been a good month for miracles. And by miracles I mean our oldest miracle, that first miracle, the creation of life itself.

During these first weeks in May, two separate teams working at two separate institutions announced that when it comes to creating life from scratch, well, there are a couple of new gods in town.

VIRUS: Rebutting the fear of synthetic biology @HJBentham @IEET

Posted by in categories: biological, biotech/medical, disruptive technology, economics, energy, ethics, existential risks, futurism, genetics, science

- @ClubOfINFO — A recent massive leap forward in synthetic life, recently published in Nature, is the expansion of the alphabet of DNA to six letters rather than four, by synthetic biologists – the technicians to whom we entrust the great task of reprogramming life itself.

Breakthroughs such as the above are quite certain to alert more and more people to synthetic biology and its possible consequences. For as long as such breathtaking discoveries continue to be made in this area of research, it is inevitable that latent fears among society will come closer to the surface.
There is likely to be a profound distrust, whether inculcated by religion or by science fiction horror movies and literature, towards the concept of tampering with nature and especially the very building blocks that brought us into existence. While the people with this profoundly negative reaction are not sure what they are warning against, they are motivated by a vitalistic need to believe that the perversion of life is going to provoke hidden – almost divine – repercussions.
Is it really true that no-one should be meddling with something so fundamental to life, or is synthetic biology the science of our century, our civilization’s key to unlimited energy? Whatever the answer may be, the science enabling it already exists and is growing rapidly, and history seems to show that any technology once invented is impossible to contain.
The fact that synthetic base pairs now exist should confirm, for many, the beginning of humanity’s re-engineering of the structures of life itself. As it is unprecedented in our evolution, we are presented with an ethical question and all points of view should be considered, no matter how radical or conservative they are.

Scientists Reconnect Severed Nerves With Liquid Metal

Scientists Have Reconnected Severed Nerves with Liquid Metal

Get your T-1000 jokes ready, because we’re one step closer to liquid metal-powered people. As a team of Chinese biomedical engineers recently used an alloy to close the gap between severed sciatic nerves in frogs. In effect, it made electronic circuits out of nerves — and it worked.

Shockingly, this sci-fi solution is as simple as it sounds. Looking for a way to keep muscles active while nerves healed, the Tsinghua University researchers identified liquid metal as a highly conductive but also safe material to bridge the gap. They decided on the liquid metal alloy gallium-indium-selenium, a benign material that’s liquid at body temperature. (This liquid metal is not to be confused with the brand-name wonder material Liquidmetal, which is not actually a liquid.) The liquid metal alloy is also highly conductive.

The Transhuman Olympics: Where Entertainment Meets Innovation

Posted by in categories: biotech/medical, evolution, futurism, transhumanism

Since the first modern Olympic Games bowed in Athens in 1896, humanity has gradually integrated the developments of science and technology into the realm of competitive sport.

The various attempts to slow the utilization of advanced materials, pharmaceuticals, biotechnology, and robotics is akin to keeping certain gender or ethnic groups out of the games. Not just discrimination, but impeding the flow of progress.

transhuman olympicsIf the ultimate goal of world-level competition is advancement of human physical ability, then athletes, coaches, physicians, and biotech engineers should be able to choose the very best tactics and strategies to achieve that goal.

A Transhuman Olympics would be wildly entertaining, but would also spur the development of biotechnology at a pace that public and private science could never keep up with. While the ethics of such an event might be hotly contested, the benefits to humankind would be lasting and far reaching.

R U Ready to be Uploaded?

How has your work, your life, your humanity, been improved by the promise of Big Data?

What apps and online media do you use to upload personal and other info?

Singularity has flopped – that is to say, this week Johnny Depp’s new film Transcendence did not bring in as much as Pirates of the Caribbean. Though there may not have been big box office heat, there is heat behind the film’s subject: Big Data! Sure we miss seeing our affable pirate chasing treasure, but hats off to Mr. Depp who removed his Keith Richards make-up to risk chasing what might be the mightiest challenge of our century.

Singularity, coined by mathematician John von Neumann, is a heady mathematical concept tested by biotech predictions. Made popular by math and music wunderkindt turned gray hair guru of an AI movement Ray Kurzweil, Singularity is said to signify the increasing rate at which artificial intelligence will supersede human intelligence like a jealous sibling. Followers of the Singularity movement (yes, with guru comes followers) envision the time of override in the not to distant future with projections set early as 2017 and 2030. At these times, the dynamics of technology are said to set about a change in our biology, our civilization and “perhaps” nature itself. Within our current reach, we see signs of empowered tech acting out in the current human brain mapping quest and brain-computer interface systems. More to the point, there is an ever increasing onslaught of Google Alerts annoucing biotech enhancements with wearable tech. Yes indeed, here comes the age of smart prosthetics and our own AI upload of medical and personal data to the internet. Suddenly all those Selfies seem more than mere narcissistic postings against the imposing backdrop of Big Data.
