It would be helpful to discuss these theoretical concepts because there could be significant practical and existential implications.
The Global Brain (GB) is an emergent world-wide entity of distributed intelligence, facilitated by communication and the meaningful interconnections between millions of humans via technology (such as the internet).
For my purposes I take it to mean the expressive integration of all (or the majority) of human brains through technology and communication, a Metasystem Transition from the human brain to a global (Earth) brain. The GB is truly global not only in geographical terms but also in function.
It has been suggested that the GB has clear analogies with the human brain. For example, the basic unit of the human brain (HB) is the neuron, whereas the basic unit of the GB is the human brain. Whilst the HB is space-restricted within our cranium, the GB is constrained within this planet. The HB contains several regions that have specific functions themselves, but are also connected to the whole (e.g. occipital cortex for vision, temporal cortex for auditory function, thalamus etc.). The GB contains several regions that have specific functions themselves, but are connected to the whole (e.g. search engines, governments, etc.).

I believe that death due to ageing is not an absolute necessity of human nature. From the evolutionary point of view, we age because nature withholds energy for somatic (bodily) repairs and diverts it to the germ-cells (in order to assure the survival and evolution of the DNA). This is necessary so that the DNA is able to develop and achieve higher complexity.
Although this was a valid scenario until recently, we have now evolved to such a degree that we can use our intellect to achieve further cognitive complexity by manipulating our environment. This makes it unnecessary for the DNA to evolve along the path of natural selection (which is a slow and cumbersome, ‘hit-and-miss’ process), and allows us to develop quickly and more efficiently by using our brain as a means for achieving higher complexity. As a consequence, death through ageing becomes an illogical and unnecessary process. Humans must live much longer than the current lifespan of 80–120 years, in order for a more efficient global evolutionary development to take place.
It is possible to estimate how long the above process will take to mature (see figure below). Consider that the creation of the DNA was approximately 2 billion years ago, the formation of a neuron (cell) several million years ago, that of an effective brain (Homo sapiens sapiens) 200 000 years ago, and the establishment of complex societies (Ancient Greece, Rome, China etc.) thousands of years ago. There is a logarithmic reduction of the time necessary to proceed to the next more complex step (a reduction by a factor of 100). This means that global integration (and thus indefinite lifespans) will be achieved in a matter of decades (and certainly less than a century), starting from the 1960s-1970s (when globalisation in communications, travel and science/technology started to became established). This leaves another maximum of 50 years before the full global integration becomes established.
Each step is associated with a higher level of complexity, and takes a fraction of the timein order to mature, compared to the previous one.

The Stoic philosophical school shares several ideas with modern attempts at prolonging human lifespan. The Stoics believed in a non-dualistic, deterministic paradigm, where logic and reason formed part of their everyday life. The aim was to attain virtue, taken to mean human excellence.
I have recently described a model specifically referring to indefinite lifespans, where human biological immortality is a necessary and inevitable consequence of natural evolution (for details see www.elpistheory.info and for a comprehensive summary see http://cid-3d83391d98a0f83a.office.live.com/browse.aspx/Immo…=155370157).
This model is based on a deterministic, non-dualistic approach, described by the laws of Chaos theory (dynamical systems) and suggests that, in order to accelerate the natural transition from human evolution by natural selection to a post-Darwinian domain (where indefinite lifespans are the norm) , it is necessary to lead a life of constant intellectual stimulation, innovation and avoidance of routine (see http://www.liebertonline.com/doi/abs/10.1089/rej.2005.8.96?journalCode=rej and http://www.liebertonline.com/doi/abs/10.1089/rej.2009.0996) i.e. to seek human virtue (excellence, brilliance, and wisdom, as opposed to mediocrity and routine). The search for intellectual excellence increases neural inputs which effect epigenetic changes that can up-regulate age repair mechanisms.
Thus it is possible to conciliate the Stoic ideas with the processes that lead to both technological and developmental Singularities, using approaches that are deeply embedded in human nature and transcend time.

Power plants. Trees could do a lot, as we have seen — and they’re solar powered, too. Once trees can suck metals from the soil and grow useful, shaped objects like copper wire, a few more levels of genetic engineering could enable the tree to use this copper wire to deliver electricity. Since a tree is already, now, a solar energy converter, we can build on that by having the tree grow tissues that convert energy into electricity. Electric eels can already do that, producing enough of a jolt to be lethal to humans. Even ordinary fish produce small amounts of electricity to create electric fields in the water around them. Any object nearby disrupts the field, enabling the fish to tell that something is near, even in total darkness. We may never be able to plug something into a swimming fish but we can already make batteries out of potatoes. So why not trees that grow into electricity providers all by themselves? It would be great to be able to plug your electrical devices into a tree (or at least a socket in your house that is connected to the tree). Then you would no longer need to connect to the grid, purchase solar panels, or install a windmill. You would, however, need to keep your trees healthy and vigorous! Tree care specialists would become a highly employable occupation.
Greening the desert. The Sahara and various other less notorious but still very dry deserts around the world have plenty of sand and rocks. But they don’t have much greenery. The main problem is lack of water. Vast swaths of the Sahara, for example, are plant free. It’s just too dry. However this problem is solvable! Cacti and other desert plants could potentially extract water from the air. Plants already extract carbon dioxide molecules from the air. Even very dry air contains considerable water vapor, so why not extract water molecules too. Indeed, plants already transport water molecules in the ground into their roots, so is it really such a big step to do the same from the air? Tillandsia (air plant) species can already pull in water with their leaves, but it has to be rain or other liquid water. Creating plants that can extract gaseous water vapor from the air in a harsh desert environment would require sophisticated genetic engineering, or a leap for mother nature, but it is still only the first step. Plants get nutrients out of the soil by absorbing fluid that has dissolved them, so dry soil would be a problem even for a plant that contained plenty of water pulled from the air. Another level of genetic engineering or natural evolution would be required to enable them to secrete fluid out of their roots to moisten chunks of soil to dissolve its minerals, and reabsorb the now nutritious, mineral-laden liquid back into their roots.
Once this difficult task is accomplished, whether by natural evolution in the distant future or genetic engineering sooner, things will be different in the desert. Canopies of vegetation that hide the ground will be possible. Thus shaded and sheltered, the ground will be able to support a much richer ecosystem of creatures and maybe even humans than is currently the case in deserts. One of Earth’s harshest environments would be tamed.

Over the millennia humans and the rest of nature have coexisted in various relationships. However the intimate and interdependent nature of our relationship with other beings on the planet has been recently brought to light by the oil spill in the Gulf of Mexico. This ongoing environmental disaster is a prime example of “profit over principle” regarding non-human life. This spill threatens not only the reproductive viability of all flora and fauna in the affected ecosystems but also complex and sensitive non-human cultures like those we now recognize in dolphins and whales.
Although science has, for decades, documented the links and interdependence of ecosystems and species, the ethical dilemma now facing humans is at a critical level. For too long have we not recognized the true cost of our life styles and priorities of profit over the health of the planet and the nonhuman beings we share it with. If ever the time, this is a wake up call for humanity and a call to action. If humanity is to survive we need to make an urgent and long-term commitment to the health of the planet. The oceans, our food sources and the very oxygen we breathe may be dependent on our choices in the next 10 years.
And humanity’s survival is inextricably linked to that of the other beings we share this planet with. We need a new ethic.
With our growing resources, the Lifeboat Foundation has teamed with the Singularity Hub as Media Sponsors for the 2010 Humanity+ Summit. If you have suggestions on future events that we should sponsor, please contact [email protected].
The summer 2010 “Humanity+ @ Harvard — The Rise Of The Citizen Scientist” conference is being held, after the inaugural conference in Los Angeles in December 2009, on the East Coast, at Harvard University’s prestigious Science Hall on June 12–13. Futurist, inventor, and author of the NYT bestselling book “The Singularity Is Near”, Ray Kurzweil is going to be keynote speaker of the conference.
Also speaking at the H+ Summit @ Harvard is Aubrey de Grey, a biomedical gerontologist based in Cambridge, UK, and is the Chief Science Officer of SENS Foundation, a California-based charity dedicated to combating the aging process. His talk, “Hype and anti-hype in academic biogerontology research: a call to action”, will analyze the interplay of over-pessimistic and over-optimistic positions with regards of research and development of cures, and propose solutions to alleviate the negative effects of both.

Nature News reports of a growing concern over different standards for DNA screening and biosecurity:
“A standards war is brewing in the gene-synthesis industry. At stake is the way that the industry screens orders for hazardous toxins and genes, such as pieces of deadly viruses and bacteria. Two competing groups of companies are now proposing different sets of screening standards, and the results could be crucial for global biosecurity.
“If you have a company that persists with a lower standard, you can drag the industry down to a lower level,” says lawyer Stephen Maurer of the University of California, Berkeley, who is studying how the industry is developing responsible practices. “Now we have a standards war that is a race to the bottom.”
Unique opportunity to sponsor research investigating an infectious cause and potential treatment for Alzheimer’s disease
In these financially difficult times many funding bodies have to prioritise projects based around long established hypotheses. Projects involving new avenues of investigation can receive very positive comments by scientific reviewers, yet are rarely funded, as they almost always appear risky compared with projects largely confirming or expanding existing ideas. Such conservative projects are almost guaranteed to produce useful data, though with modest impact. This situation can mean that research proposals with the potential to transform our understanding of a disease and offer new approaches to its treatment never reach the threshold for funding and are not implemented, even though the potential and quality of the science is acknowledged by reviewers and funding panel.
It appears that our work examining a viral cause for Alzheimer’s disease is in this category. Despite our publishing a large number of potentially very exciting papers on this topic, and despite our research projects being reviewed favourably by scientific referees, few funding panels are prepared to commit resources to fund our work, as by doing so they deny funding to other more straightforward, very low risk projects.
We are therefore actively seeking sponsorship for several projects of varying costs to investigate the interaction of virus and specific genetic factor, the pathways of viral damage in the brain, and the effects of antiviral agents. All the projects would provide significant evidence strengthening the case for trialling antiviral agents in Alzheimer’s disease.
Antiviral agents would inhibit a likely major cause of the disease in contrast to current treatments, which merely inhibit the symptoms.
If any Lifeboat member knows of a company or individual that would be interested in sponsoring some of our research on Alzheimer’s disease then please contact me for further details.

It will probably come as a surprise to those who are not well acquainted with the life and work of Alan Turing that in addition to his renowned pioneering work in computer science and mathematics, he also helped to lay the groundwork in the field of mathematical biology(1). Why would a renowned mathematician and computer scientist find himself drawn to the biosciences?
Interestingly, it appears that Turing’s fascination with this sub-discipline of biology most probably stemmed from the same source as the one that inspired his better known research: at that time all of these fields of knowledge were in a state of flux and development, and all posed challenging fundamental questions. Furthermore, in each of the three disciplines that engaged his interest, the matters to which he applied his uniquely creative vision were directly connected to central questions underlying these disciplines, and indeed to deeper and broader philosophical questions into the nature of humanity, intelligence and the role played by evolution in shaping who we are and how we shape our world.
Central to Turing’s biological work was his interest in mechanisms that shape the development of form and pattern in autonomous biological systems, and which underlie the patterns we see in nature (2), from animal coat markings to leaf arrangement patterns on plant stems (phyllotaxis). This topic of research, which he named “morphogenesis,” (3) had not been previously studied with modeling tools. This was a knowledge gap that beckoned Turing; particularly as such methods of research came naturally to him.
In addition to the diverse reasons that attracted him to the field of pattern formation, a major ulterior motive for his research had to do with a contentious subject which, astonishingly, is still highly controversial in some countries to this day. In studying pattern formation he was seeking to help invalidate the “argument from design” (4) concept, which we know today as the hypothesis of “Intelligent Design.”
