Since the moment humans became aware of their existence, they have been haunted by the knowledge that it will inevitably come to an end and the hope to change this unfortunate fate.
This month, during Brain Bar Budapest – Europe’s leading conference on the future – Stephen Cave talked about the four immortality stories we tell ourselves and how they are changing in the context of new scientific discoveries and technological advancements. Stephen Cave spent a decade studying and teaching philosophy, and was awarded his PhD in metaphysics from the University of Cambridge in 2001. He is Executive Director of the Leverhulme Centre for the Future of Intelligence and Senior Research Associate at the University of Cambridge.
June 22 (UPI) — In a series of experiments, neuroscientists were able to selectively delete different types of memories stored a single neuron belonging to a marine snail.
The feat, detailed in the journal Current Biology, suggests problematic memories — like those responsible for PSTD and anxiety — in the human brain could be excised without harming other memories.
When the brain stores a traumatic experience in its memory bank, the memory is actually stored in multiple forms. Each memory can include bits of incidental information from the experience. Years later, these incidental, or neutral, memories can trigger panic attacks and severe anxiety.
University of Alberta researcher Marty Mrazik, Ph.D., says being bright may be due to an excess level of a natural hormone.
Mrazik, and a colleague have published a paper in Roeper Review linking giftedness (having an IQ score of 130 or higher) to prenatal exposure of higher levels of testosterone.
Mrazik hypothesizes that, in the same way that physical and cognitive deficiencies may develop in utero, so too could similar exposure to this naturally occurring chemical result in giftedness.
A conspiracy theory article that I think is spreading semi-fake news (but it’s interesting to see how some people react to #transhumanism):
While the title of this article may sound like it belongs on a strange and dark science fiction movie, it doesn’t. Unfortunately, it seems that as the technological world continues to advance, the more the old adage ‘the truth is stranger than fiction’ becomes true.
Throughout the past year or so, we have heard Google’s leading futurist tell us that it will one day be possible to live forever. His belief is that it will start with nanobots in the human body which would work to defeat deadly disease, in place of our immune system. Kurzweil maintains that the human immune system is inadequate and that,
“Your immune system, for example, does a poor job on cancer,” he told Playboy.” It thinks cancer is you. It doesn’t treat cancer as an enemy. It also doesn’t work well on retroviruses. It doesn’t work well on things that tend to affect us later in life because it didn’t select for longevity.”
He also believes that the nanobots will enhance humanity and bring us to a point we could never have reached on our own. “We’re going to be funnier. We’re going to be sexier. We’re going to be better at expressing loving sentiment.”
New story about the recent book on #transhumanism To Be a Machine:
For the (very very quickly) upcoming Love & Death Issue, I had the chance to interview the journalist, Mark O’Connell, who is the author most recently of To Be A Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death. He also wrote that amazing piece in the New York Times Magazine a few months ago about Zoltan Istvan, the transhumanist who ran for president and drove across the country in a coffin-shaped bus. O’Connell’s new book reads like a travelogue among characters like Zoltan, futuristic types (mostly from California) that O’Connell describes with a charming blend of cynicism and aloof interest. Like an agnostic amidst a group of “true believers,” O’Connell is both repelled by and drawn in by the belief system that transhumanism proffers.
If you’re unfamiliar, transhumanism is the movement that asserts an immortal future thanks to technology and science. As O’Connell describes it, it is the technological teleology of salvation: “a projection whereby intelligent life takes over all matter in the universe, leading to a cosmological singularity.” In other words, the computers we’ve built, the science we’re discovering, will free us from our mortal coil, our bodies. We will live eternally in new bodies, machines unconstrained by sickness, vulnerability and death.
You can see how O’Connell hears the religious bells ringing. But he also, throughout the book, describes this paradox: that this futurism is just a new iteration of a very old idea. Despite all the science fiction lingo used to describe this singularity (“longevity escape velocity,” “whole brain emulation,” “cyborgs”), what we really have is the apex of Enlightenment thought, and before that, Gnostic thought. It is the idea that we are liberated by our minds, that certain refinements of knowledge will set us free.
Beneath the talk of future technologies, I could hear the murmur of ancient ideas. We were talking about the transmigration of souls, eternal return, reincarnation. Nothing is ever new. Nothing ever truly dies, but is reborn in a new form, a new language, a new substrate.
Organs-on-Chips (Organ Chips) are emerging as powerful tools that allow researchers to study the physiology of human organs and tissues in ways not possible before. By mimicking normal blood flow, the mechanical microenvironment, and how different tissues physically interface with one another in living organs, they offer a more systematic approach to testing drugs than other in vitro methods that ultimately could help to replace animal testing.
As it can take weeks to grow human cells into intact differentiated and functional tissues within Organ Chips, such as those that mimic the lung and intestine, and researchers seek to understand how drugs, toxins or other perturbations alter tissue structure and function, the team at the Wyss Institute for Biologically Inspired Engineering led by Donald Ingber has been searching for ways to non-invasively monitor the health and maturity of cells cultured within these microfluidic devices over extended times.
It has been particularly difficult to measure changes in electrical functions of cells grown within Organ Chips that are normally electrically active, such as neuronal cells in the brain or beating heart cells, both during their differentiation and in response to drugs.
The human mind is already pretty open to manipulation—just ask anyone who works in advertising. But neural implant technology could potentially open up a direct digital link to our innermost thoughts that could be exploited by hackers.
In recent months, companies like Elon Musk’s Neuralink, Kernel, and Facebook have unveiled plans to create devices that will provide a two-way interface between human brains and machines.
While these devices could undoubtedly bring many benefits, they would be networked to computers and therefore essentially part of the Internet of Things. That should immediately set off alarm bells for anyone paying attention to cybersecurity news.
New research suggests that the human brain is almost beyond comprehension because it doesn’t process the world in two dimensions or even three. No, the human brain understands the visual world in up to 11 different dimensions.
The astonishing discovery helps explain why even cutting-edge technologies like functional MRIs have such a hard time explaining what is going on inside our noggins. In a functional MRI, brain activity is monitored and represented as a three-dimensional image that changes over time. However, if the brain is actually working in 11 dimensions, looking at a 3D functional MRI and saying that it explains brain activity would be like looking at the shadow of a head of a pin and saying that it explains the entire universe, plus a multitude of other dimensions.
The team of scientists led by a group from Scientists at the École Polytechnique Fédérale de Lausanne in Switzerland detected the previously unknown complexities of the brain while working on the Blue Brain Project. The project’s goal is to create a biologically accurate recreation of the human brain.
