Neurons still remain the most powerful piece of computation machinery on the face of the planet. More to the point, nobody throws up their hands in despair when a screwdriver removes a flathead screw better than their fingernail can, and yet the parallel is an apt one. The circuitry of the human brain has not been honed by evolution to be especially good at playing the game of Go, any more than evolution has fine-tuned our fingernails for removing screws.

Which is not to say there is no room for surprise in today’s world of rapidly advancing technological achievement. What is more impressive, however, is when computers exhibit greater skill than humans at tasks evolution has been perfecting for millions of years like exercising a sense of smell. And yet such advancements are taking place right beneath our noses, metaphorically speaking.

Recently a UK startup called Koniku released details on a drone that uses neurons embedded in a computer architecture to achieve the sense of smell exhibited by a bee. With only 64 neurons, the chip achieves a sense of smell capable of detecting explosives over one kilometer away. The accompanying video bears testimony to this amazing achievement, as the drone in question hones in on its target with almost bee like movement. In fact, the only thing missing is an incessant buzzing noise.

“He is not here; He has risen,” — Matthew 28:6

As billions of Christians around the world are getting ready to celebrate the Easter festival and holiday, we take pause to appreciate the awe inspiring phenomena of resurrection.

crypt

In religious and mythological contexts, in both Western and Eastern societies, well known and less common names appear, such as Attis, Dionysus, Ganesha, Krishna, Lemminkainen, Odin, Osiris, Persephone, Quetzalcoatl, and Tammuz, all of whom were reborn again in the spark of the divine.

In the natural world, other names emerge, which are more ancient and less familiar, but equally fascinating, such as Deinococcus radiodurans, Turritopsis nutricula, and Milnesium tardigradum, all of whose abilities to rise from the ashes of death, or turn back time to start life again, are only beginning to be fully appreciated by the scientific world.

In the current era, from an information technology centric angle, proponents of a technological singularity and transhumanism, are placing bets on artificial intelligence, virtual reality, wearable devices, and other non-biological methods to create a future connecting humans to the digital world.

This Silicon Valley, “electronic resurrection” model has caused extensive deliberation, and various factions to form, from those minds that feel we should slow down and understand the deeper implications of a post-biologic state (Elon Musk, Steven Hawking, Bill Gates, the Vatican), to those that are steaming full speed ahead (Ray Kurzweil / Google) betting that humans will shortly be able to “transcend the limitations of biology”.

However, deferring an in-depth Skynet / Matrix discussion for now, is this debate clouding other possibilities that we have forgotten about, or may not have even yet fully considered?

Today, we find ourselves at an interesting point in history where the disciplines of regenerative sciences, evolutionary medicine, and complex systems biology, are converging to give us an understanding of the cycle of life and death, orders of magnitude more complex than only a few years ago.

In addition to the aforementioned species that are capable of biologic reanimation and turning back time, we show no less respect for those who possess other superhuman capabilities, such as magnetoreception, electrosensing, infrared imaging, and ultrasound detection, all of which nature has been optimizing over hundreds of millions of years, and which provide important clues to the untapped possibilities that currently exist in direct biological interfaces with the physical fabric of the universe.

The biologic information processing occurring in related aneural organisms and multicellular colony aggregators, is no less fascinating, and potentially challenges the notion of the brain as the sole repository of long-term encoded information.

Additionally, studies on memory following the destruction all, or significant parts of the brain, in regenerative organisms such as planarians, amphibians, metamorphic insects, and small hibernating mammals, have wide ranging implications for our understanding of consciousness, as well as to the centuries long debate between the materialists and dualists, as to whether we should focus our attention “in here”, or “out there”.

I am not opposed to studying either path, but I feel that we have the potential to learn a lot more about the topic of “out there” in the very near future.

The study of brain death in human beings, and the application of novel tools for neuro-regeneration and neuro-reanimation, for the first time offer us amazing opportunities to start from a clean slate, and answer questions that have long remained unanswered, as well as uncover a knowledge set previously thought unreachable.

Aside from a myriad of applications towards the range of degenerative CNS indications, as well as disorders of consciousness, such work will allow us to open a new chapter related to many other esoteric topics that have baffled the scientific community for years, and fallen into the realm of obscure curiosities.

From the well documented phenomena of terminal lucidity in end stage Alzheimer’s patients, to the mysteries of induced savant syndrome, to more arcane topics, such as the thousands of cases of children who claim to remember previous lives, by studying death, and subsequently the “biotechnological resurrection” of life, we can for the first time peak through the window, and offer a whole new knowledge base related to our place, and our interaction, with the very structure of reality.

We are entering a very exciting era of discovery and exploration.

Genetic mutations from extinct human relatives called the Denisovans might have influenced modern human immune systems, as well as fat and blood sugar levels, researchers say.

Very little is known about the Denisovans. The first evidence of them was discovered in Denisova Cave in Siberia in 2008, and DNA from their fossils suggests they shared an origin with Neanderthals but were nearly as genetically distinct from Neanderthals as Neanderthals were from modern humans.

Previous work found that any modern humans with ancestry outside of Africa inherited about 1.5 to 2.1 percent of their DNA from Neanderthals. In contrast, prior research suggested that substantial levels of Denisovan ancestry are found only in the Pacific islands of Melanesia. Scientists are increasingly uncovering the effects of Neanderthal ancestry on modern humans, from potential immune boosts to increased risks for depression, obesity, heart attacks, nicotine addiction. However, relatively little was known about the effects of Denisovan ancestry.

The body’s branching network of peripheral nerves connects neurons in the brain and spinal cord to organs, skin, and muscles, regulating a host of biological functions from digestion to sensation to locomotion. But the peripheral nervous system can do even more than that, which is why DARPA already has research programs underway to harness it for a number of functions—as a substitute for drugs to treat diseases and accelerate healing, for example, as well as to control advanced prosthetic limbs and restore tactile sensation to their users.

Now, pushing those limits further, DARPA aims to enlist the body’s peripheral nerves to achieve something that has long been considered the brain’s domain alone: facilitating learning. The effort will turn on its head the usual notion that the brain tells the peripheral nervous system what to do.

The new program, Targeted Neuroplasticity Training (TNT), seeks to advance the pace and effectiveness of a specific kind of learning—cognitive skills training—through the precise activation of peripheral nerves that can in turn promote and strengthen neuronal connections in the brain. TNT will pursue development of a platform technology to enhance learning of a wide range of cognitive skills, with a goal of reducing the cost and duration of the Defense Department’s extensive training regimen, while improving outcomes. If successful, TNT could accelerate learning and reduce the time needed to train foreign language specialists, intelligence analysts, cryptographers, and others.

The fact that some people remember the past as a series of episodes full of details (episodic memory), while others store in their brains the meaning of events (semantic memory), has a lot to do with the configuration of the connections in the brain, according to a recent study published in the journal Cortex. Neuroscience is deciphering the sophisticated mechanisms of human memory to explain how we file and remember information.

– Memory’s unreliable.

– Oh please!

– No, no, really! Memory’s not perfect. (…) Memory can change the shape of a room. It can change the color of a car and memories can be distorted. Memories are just an interpretation. They’re not a record. They’re irrelevant if you have the facts.

This is the conversation between Leonard and Teddy in the key scene of the movie Memento, one of the movies that best reflects the neuroscientific knowledge about memory. Its main character suffers from anterograde amnesia, which though it allows him to remember new words, he is unable to remember the recent past.

The EU-funded COLUMNARCODECRACKING project has successfully used ultra-high fMRI scanners to map cortical columns, a process that opens the door to exciting new applications, such as brain-computer interfaces.

Cortical columnar-level fMRI has already contributed and will further contribute to a deeper understanding of how the brain and mind work by zooming into the fine-grained functional organization within specialized brain areas.

By focussing on this, the project has stimulated a new research line of ‘mesoscopic’ brain imaging that is gaining increasing momentum in the field of human cognitive and computational neuroscience. This new field complements conventional macroscopic brain imaging that measures activity in brain areas and large-scale networks.
