Can nanotechnology rewire an injured spinal cord?

Posted by in categories: biotech/medical, computing, economics, education, health, nanotechnology, neuroscience

According to the World Health Organisation, up to a half-million people around the world suffer a spinal cord injury each year. Often caused by road traffic crashes, accidents or violence, the loss of motor control or paralysis significantly impacts quality of life and requires years of treatment and care. Spinal cord injury is also associated with lower rates of school enrollment and economic participation, and carries substantial individual and societal costs.

Current methods for spinal cord injury treatment involve cumbersome brain-machine interfaces, with many cables linking the patient and a computer to restore limited motor functions. Other methods to map , such as magnetoencephalography, require very large machinery and particularly low-temperature working conditions.

MSD scientists to tackle diseases of ageing at the Crick

Posted by in categories: biotech/medical, life extension, neuroscience

Scientists from global biopharmaceutical company MSD will come to the Crick next year to tackle a range of conditions associated with ageing such as dementia and Parkinson’s disease.

A new team of around 15 MSD chemists and pharmacologists will be based at the Crick over the next five years, working to develop new understandings of diseases that affect the UK’s ageing population.

The scientists will be based at the Crick while MSD establishes their new discovery science centre and UK headquarters in London, the location of which is being finalised. Their work will complement the MSD neuroscience cell biology team already established at the London Bioscience Innovation Centre, and both teams will eventually move to MSD’s new centre.

AI Created in DNA-Based Artificial Neural Networks

Posted by in categories: bioengineering, biotech/medical, mathematics, neuroscience, robotics/AI, security

Mention artificial intelligence (AI) or artificial neural networks, and images of computers may come to mind. AI-based pattern recognition has a wide variety of real-world uses, such as medical diagnostics, navigation systems, voice-based authentication, image classification, handwriting recognition, speech programs, and text-based processing. However, artificial intelligence is not limited to digital technology and is merging with the realm of biology—synthetic biology and genomics, to be more precise. Pioneering researchers led by Dr. Lulu Qian at the California Institute of Technology (Caltech) have created synthetic biochemical circuits that are able to perform information processing at the molecular level–an artificial neural network consisting of DNA instead of computer hardware and software.

Artificial intelligence is in the early stages of a renaissance period—a rebirth that is largely due to advances in deep learning techniques with artificial neural networks that have contributed to improvements in pattern recognition. Specifically, the resurgence is largely due to a mathematical tool that calculates derivatives called backpropagation (backward propagation)—it enables artificial neural networks to adjust hidden layers of neurons when there are outlier outcomes for more precise results.

Artificial neural networks (ANN) are a type of machine learning method with concepts borrowed from neuroscience. The structure and function of the nervous system and brain were inspiration for artificial neural networks. Instead of biological neurons, ANNs have artificial nodes. Instead of synapses, ANNs have connections that are able to transmit signals between nodes. Like neurons, the nodes of ANNs are able to receive and process data, as well as activate other nodes connected to it.

Alaska woman with MS says stem-cell treatment has left her ‘practically symptom-free’

Posted by in categories: biotech/medical, neuroscience

A young mother from Anchorage, Alaska, who was diagnosed with multiple sclerosis (MS) more than 10 years ago says an experimental stem-cell treatment has left her “practically symptom-free.”

Amanda Loy was 27 years old when she was first diagnosed with the disease, which typically affects the brain and spinal cord, also known as the central nervous system. MS can be debilitating and there is currently no cure, according to the Multiple Sclerosis International Federation.

Pioneering brain study reveals ‘software’ differences between humans and monkeys

Posted by in categories: biotech/medical, neuroscience

Neuroscientists have for the first time discovered differences between the ‘software’ of humans and monkey brains, using a technique that tracks single neurons.

They found that human brains trade off ‘robustness’ — a measure of how synchronized neuron signals are — for greater efficiency in information processing. The researchers hypothesize that the results might help to explain humans’ unique intelligence, as well as their susceptibility to psychiatric disorders. The findings were published in Cell on 17 January.

Scientists say that this type of unusual study could help them to better translate research in animal models of psychiatric diseases into the clinic.

Evolution calls on us to lose weight slowly over time

Posted by in categories: energy, evolution, food, health, neuroscience

| Local | http://idahostatejournal.com/ Cutting calories (dieting) and increasing caloric expenditure (exercise) cause your brain to activate neurons that will not allow you to utilize fat or lose weight.


Recently, and at a most appropriate time, another study published in the journal eLife has given explanation as to why your current New Year’s Resolution diet will not work.

Cutting calories (dieting) and increasing caloric expenditure (exercise) cause your brain to activate neurons that will not allow you to utilize fat or lose weight.

This Scientist Is On The Verge Of Curing Multiple Sclerosis For 2.3 Million Patients

Posted by in categories: biotech/medical, health, neuroscience

More effective treatments for Multiple Sclerosis on the horizon?


Dr. Metcalfe and her company are already looking to take down other severe diseases as well.

“Psoriasis is high up on our list, and diabetes is another. Downstream there are all the dementias because a LIF is a major health factor for the brain. So if we can get it into the brain we can start protecting against dementia.”

Are We Just Another Primate? Robert Sapolsky

Perhaps not the most complete and/or updated view on dopamine, but pretty fun short talk overall. No, we’re not that different.
