Researchers have come up with a way for making functional neurons directly from human skin cells, including those taken from patients with Alzheimer’s disease. Alzheimer’s Reading Room Asa Abeliovich The new method may offer a critical short cut for generating neurons for replacement therapies of the future, according to research published in the August 5th …“Scientists Make Neurons Directly From Human Skin”
Machines enrich and enhance our lives, whether it’s the smartphones that allow us to stay connected or the supercomputers that solve our toughest computational problems. Imagine how much more productive and innovative our world will be when computers become infinitely more powerful. Indeed, the growing field of quantum computing may make our current technological capacities look feeble and primitive in comparison. It could even transform the workings of the human brain and revolutionize how we think in ways we can’t begin to imagine.
Today, computers operate at the most basic level by manipulating two states: a zero or a one. In contrast, quantum computers are not limited to two states, but can encode information in multiple states that exist in superposition, also known as quantum bits or qubits.
In other words, this technology takes advantage of one of the most fascinating properties of the quantum world: the ability of subatomic particles to exist in more than one state at any given time. Consequently, a quantum computer can perform many calculations at the same time, whereas a traditional Turing machine can only perform a single calculation at once. Such quantum machines will be millions of times more powerful than our most powerful current computers.
Technology for reading signals directly from the brain developed by Stanford Bio-X scientists could provide a way for people with movement disorders to communicate.
The system directly reads brain signals to drive a cursor moving over a keyboard. In a pilot experiment conducted with monkeys, the animals were able to transcribe passages from the New York Times and Hamlet at a rate of 12 words per minute.
Earlier versions of the technology have already been tested successfully in people with paralysis, but the typing was slow and imprecise. This latest work tests improvements to the speed and accuracy of the technology that interprets brain signals and drives the cursor.

Cells in the hippocampus store memories of acquaintances, a new study reports.
Mice have brain cells that are dedicated to storing memories of other mice, according to a new study from MIT neuroscientists. These cells, found in a region of the hippocampus known as the ventral CA1, store “social memories” that help shape the mice’s behavior toward each other.
In Brief.
Scientists at IBM achieve another breakthrough by recreation of artificial neurons that successfully respond to phase changes due to electric signals while using very little power, much like the human brain.
Even after all the developments in computers, the human brain remains by far, the most complex, sophisticated, and powerful computer in existence. And for decades, scientists have been looking for ways to translate its processing mechanisms into a system that machines can replicate.
Boston-based startup completes $23 million Series A financing to leverage novel imaging platform of gene locations towards gaining diagnostic insights and delivering therapeutics for cancer, immuno-oncology, infectious diseases, neurological and neuromuscular diseases, brain function and cognitive disorders
BOSTON—(BUSINESS WIRE)—ReadCoor, Inc., today announced completion of an oversubscribed $23 million Series A financing round and its concurrent launch from Harvard University’s Wyss Institute for Biologically Inspired Engineering. ReadCoor will commercialize the Wyss Institute’s FISSEQ (fluorescent in situ sequencing) technology.
“But as a neuroscientist and psychologist, I have no use for the soul. On the contrary, all functions attributable to this kind of soul can be explained by the workings of the brain.”
In an astonishing breakthrough, patients left paralysed by severe spinal cord injuries have recovered the ability to move their legs after training with an exoskeleton linked to their brain – with one even able to walk using two crutches.
Scientists developed the Walk Again Project, based in Sao Paulo, Brazil, thinking that they could enable paraplegics to move about using the exoskeleton controlled by their thoughts. But they were surprised to discover that during the training, the eight patients all started to regain the sense of touch and movement below the injury to their spine. It was previously thought that the nerves in seven of the patients’ spines had been completely severed.
But the researchers now believe that a few nerves survived and these were reactivated by the training, which may have rewired circuits in the brain. Writing in the journal Scientific Reports, they said: “While patient one was initially not even able to stand using braces when placed in an orthostatic posture, after 10 months of training the same patient became capable of walking using a walker, braces and the assistance of one therapist. “At this stage, this patient became capable of producing voluntary leg movements mimicking walking, while suspended overground.
