Researchers at Duke have developed a wireless brain interface that allows monkeys to control a robotic wheelchair using only their minds.
He pointed out that Horizon Robotics will finish designing its first AI chip for smart home appliances by June and make it commercially available by early 2017.
Mainland Chinese start-up Horizon Robotics, founded by the former head of online search giant Baidu’s Institute of Deep Learning, claims it is on pace to bring chips with built-in artificial intelligence (AI) technology to market.
“General processors are too slow for AI functions. A dedicated chip will dramatically increase the speed of these functions,” Yu Kai, the founder and chief executive of Horizon Robotics told the South China Morning Post.

At this rate, we may see Ray Kurzweil’s vision of connected humans to the cloud and full singularity before 30 years.
Duke University scientists have given a pair of monkeys the ability to drive a wheelchair with their thoughts alone. The work is described in a paper recently published in the journal Scientific Reports and adds to a growing body of work in brain-machine interfaces aiming to return some freedom to the severely disabled.

The Allen Institute for Brain Science is releasing new, highly realistic computer models of neurons. The models were developed using tools and expertise from the Blue Brain Project.
The Allen Institute for Brain Science and the Blue Brain Project are deepening their collaboration. Today, the US-based Allen Institute is releasing a set of 40 computer models of neurons from the mouse visual cortex, created using tools developed by the Swiss-based Blue Brain Project at EPFL. Using Blue Brain technology, the researchers were able to reproduce the physiology and electrical activity of the neurons with an extremely high level of detail.
The Blue Brain Project is the simulation core of the Human Brain Project, a huge pan-European initiative. The scientific journal Cell recently published a long paper demonstrating the effectiveness of the Blue Brain Project’s modeling tools, focusing on the high accuracy and predictive power of the models and the discoveries they have already led to, including insight into the unexpected role of calcium. At the same time, the team has made these resources available to researchers around the world on a web-based platform.
Using his knowledge of how genes are organized and repaired in human cells, Dr. Graham Dellaire, Dalhousie Medical School’s Cameron Research Scientist in Cancer Biology, has developed a technique that could make gene therapy more effective and safer to use. His work was recently published in Nucleic Acids Research and Nature.
CRISPR, named 2015’s breakthrough discovery of the year, stands for “Clustered Regularly-Interspaced Short Palindromic Repeats.” It can accurately target and edit DNA, offering the potential to cure genetic diseases and find new treatments for cancer.
To apply CRISPR in non-dividing cells—such as those in muscle and brain tissue—researchers must first make them behave like cells that divide. They do this by turning on a cellular process called homologous recombination, which protects DNA; the recombination allows a cell’s genes to be manipulated and rearranged without the possibility of causing more harm than good.
The first step to understanding how any system works is to identify its parts.
In a pair of papers published Thursday in Cell, researchers from the Mortimer B. Zuckerman Mind Brain and Behavior Institute announced that they identified 50 different types of inhibitory interneurons—neurons that play an important role in regulating movement—in mice spines. This is the first comprehensive classification of spinal inhibitory interneurons.
The researchers also found that types of interneurons cluster and form connections with motor neuron pools, which are groups of motor neurons tied to the movement of a single muscle. This discovery suggests that different interneuron types have distinct purposes related to movement, which could help researchers better understand motor control in the nervous system.

A 3D-printed layered structure that incorporates neural cells to mimic the structure of brain tissue has been created by researchers at the ARC Centre of Excellence for Electromaterials Science (ACES) in Australia, and it could have major consequences in studying and treating conditions such as schizophrenia and Alzheimer’s. The three-dimensional structure will allow scientists to better understand the complex nature of the brain and its 86 billion nerve cells. We look at the benefits and risks of this scientific breakthrough on the Lip News with Jose Marcelino Ortiz and Jo Ankier.
