Scientists Discover How the Human Brain Folds

Scientists were able to study brain growth using a 3D gel model in order to see how the human brain gets its folds.

New research shows that our brains are likely folded because, as they grow, a large amount of volume has to fit in a small space (AKA, our skulls). This compression is actually beneficial, the folds reduce the length of neuronal wiring, improving cognitive function.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences teamed up with scientists in Finland and France to find out more about the folding process.

Graphene Brain Implants May Help Patients Regain Sensory Functions And Control Motor Disorders

Graphene; the material for brain chip implants; however, Q-Dots ferrofluid is where it will make us totally rethink brain implants in the future.

A new technology developed by researchers in Italy and the United Kingdom allows for the creation of graphene-based materials that can be interfaced with neurons without losing its electrical conductivity. This can lead to the creation of neural electrodes that are not only biocompatible, but stable within the body as well. (Photo : University of Cambridge)

Scientists from the United Kingdom and Italy have developed a new process in which a carbon form known as graphene is combined with neurons without sacrificing the integrity of these cells.

This revolutionary technology is believed to be a stepping stone for the creation of graphene-based electrodes, which can be implanted in the brain of people with motor disorders, such as Parkinson’s disease, in order to regain control of their damaged limbs.

Nootropic Drug Can Reverse And Prevent Cognitive Decline In Rats

Ampakines are known mental stimulants, but in rats they can also shelter the brain from age-related decline and even reverse deterioriation

A number of changes happen in the aging brain and one of these is a dendritic loss which onsets around middle age. In a new study, researchers have shown a particular drug belonging to the ampakine class of compounds, has significant neuroprotective properties.

Shielding the brain

Ampakines have already been shown to aid cognitive function in older rats, and they also appear to boost levels of BDNF, brain derived neurotrophic factor, which is associated with staving off neural decline. In the latest study using one such ampakine, older rat brains were compared to adolescent samples. While untreated rats had short dendrites and fewer dendritic branches, after 3 months of treatment older rat brains were identical to younger ones. If that wasn’t enough, they showed enhanced signalling and even had more dendritic spines than the adolescent rats did.

Quantum gas, liquid and crystal all-in-one

I don’t claim to be the expert on all things Quantum by no stretch; however, this is an amazing discovery and huge step forward for Quantum.

Quantum gas and liquid/ ferrofluid (quantum fluid made of tiny magnets). Now there’s a concept. Q-Dots as ferrofluid flowing through out your system (which is already comprised of about 72% H2O; think about how liquid Q-Dots can be easily absorb as a liquid and given your brain, heart, etc. run on electro charges and sensors; it could definitely open the discussion why even bother with nuero implants when Q-ferrofluid could actually be absorbed and manipulated to target the right areas for fighting diseases or improving brain functions.

The world of quantum mechanics happens only in small scales around a few nanometers. In this nanoworld, particles can behave like waves, and vice versa and have only some probability to be in a particular region. These effects can be directly observed in ultracold dilute gases. For this purpose thousands or a million atoms are cooled down to a few billionth of a degree above absolute zero. At such low temperatures particles become indistinguishable und unite collecitvely to a single giant matter wave called Bose-Einstein condensate which has astonishing properties. The matter wave flows as quantum fluid practically without inner friction, thus it is namedsuperfluid.

Researchers around Tilman Pfau at the Center for Integrated Quantum Science and Technology IQST in Stuttgart (Germany) created such a quantum fluid made of tiny magnets – that are atoms of the most magnetic element dysprosium. They call it “quantum ferrofluid” since it is superfluid and has magnetic properties similar to classical ferrofluids. Ferrofluids consist of ferromagnetic nanoparticles dissolved in oil or water. When a strong magnetic field is applied perpendicular to the surface of the ferrofluid it undergoes a so-called Rosensweig instability. The surface is no longer smooth like normal fluids, but it generates a regular thorny surface resembling a hedgehog. From the point view of the tiny magnets in a ferrofluid, every south- and northpole attract each other. Therefore, it is energetically favourable to be on top of each other along the field direction, so the fluid grows peaks out of the smooth surface.

For their investigations the researchers from Stuttgart created a quantum ferrofluid with 15,000 atoms and induced a magnetic instability. They observed then the emergence of regular patterns consisting of microscopic droplets, similar to the Rosensweig instability of ferrofluids. Each droplet has a radius smaller than 1 µm and their existence was not expected with the current state of research on these systems. Their observation could thus lead to a new field of research, as the researchers expect quantum fluctuations, related to Heisenberg’s uncertainty principle,to play an important role in the droplet existence. These quantum fluctuations allow a unique state of matter that connects opposite properties of gases, crystals and superfluids. This connectioncould be the path to a so-called supersolid, a spatially ordered material with superfluid properties.

“Some scientists refer to this as the Singularity. I call it Transcendence.”

http://www.transcendencemovie.com/

Dr. Will Caster: “For 130,000 years, our capacity for reason has remained unchanged. The combined intellect of the neuroscientists, engineers, mathematicians and hackers in this auditorium pales in comparison to even the most basic AI. Once online, a sentient machine will quickly overcome the limits of biology. And in a short time, its analytical power will be greater than the collective intelligence of every person born in the history of the world. So now imagine such an entity with the full range of human emotion. Even self-awareness. Some scientists refer to this as ‘the Singularity’. I call it ’Transcendence’. The path to building such a super-intelligence requires us to unlock the most fundamental secrets of the universe. What is the nature of consciousness? Is there a soul? And if so, where does it reside?”

Luddite: “Dr. Caster.”

Dr. Will Caster: “Yes, sir? You have a question?”

Luddite: “So you want to create a God? Your own God?”

Dr. Will Caster: “That’s a very good question. Um… Isn’t that what man has always done?”

Hexagon Resources to access high-purity graphite markets in 2017

Graphene is coming to the market in Q3 2017 by Hexagon Resources. What is also important about this is not only what graphene does for batteries; is 1 day ago when researchers in Italy released their findings in how graphene can be implanted in the brain without damaging brain cells. Therefore, there is huge potential for grapheme beyond batteries and electronics.

Hexagon Resources is on track for first production next year at its McIntosh project in Western Australia, where the country’s biggest flake graphite resource is already demonstrating huge potential for meeting high-value markets and growing significantly in size.

Robot drills electrodes into British teen’s brain, cures epilepsy

A British teenager has become the first child in the UK to be cured of epilepsy by a robot that drilled deep into his brain.

Billy Whitaker, 15, had suffered daily seizures for seven years until the operation two weeks ago, which medical experts are convinced has cured him.

The procedure used a £350,000 ($503,455) robot, practically the same as those used on car factory production lines, to drill electrodes into Whitaker’s brain.
