New algorithm points the way towards regrowing limbs and organs

Posted by in categories: biotech/medical, computing, information science, neuroscience

An international team of researchers has developed a new algorithm that could one day help scientists reprogram cells to plug any kind of gap in the human body. The computer code model, called Mogrify, is designed to make the process of creating pluripotent stem cells much quicker and more straightforward than ever before.

A pluripotent stem cell is one that has the potential to become any type of specialised cell in the body: eye tissue, or a neural cell, or cells to build a heart. In theory, that would open up the potential for doctors to regrow limbs, make organs to order, and patch up the human body in all kinds of ways that aren’t currently possible.

It was Japanese researcher Shinya Yamanaka who first reprogrammed cells in this way back in 2007 — it later earned him a Nobel Prize — but Yamanaka’s work involved a lot of labourious trial and error, and the process he followed is not an easy one to reproduce. Mogrify aims to compute the required set of factors to change cells instead, and it’s passed its early tests with flying colours.

How Technology Changes the Way We Diagnose and Treat Mental Illness

Posted by in categories: biological, biotech/medical, disruptive technology, homo sapiens, neuroscience

As recently as 50 years ago, psychiatry lacked a scientific foundation, the medical community considered mental illness a disorder of the mind, and mental patients were literally written off as “sick in the head.” A fortunate turn in progress has yielded today’s modern imaging devices, which allow neuroscientists and psychiatrists to examine the brain of an individual suffering from a mental disorder and provide the best treatment options. In a recent interview, Columbia University Psychiatry Chair Dr. Jeffrey Lieberman stated that new research into understanding the mind is growing at an accelerated pace.

Lieberman noted that, just as Galileo couldn’t prove heliocentrism until he had a telescope, psychiatry lacked the technological sophistication, tools, and instruments necessary to get an understanding of the brain until the 1950s. It wasn’t until the advent of psychopharmacology and neuroimaging, he said, that researchers could look inside the so-called black box that is the brain.

“(It began with) the CAT scan, magnetic resonance imaging (MRI) systems, positron emission tomography (PET scans) and then molecular genetics. Most recently, the burgeoning discipline of neuroscience and all of the methods within, beginning with molecular biology and progressing to optogenetics, this capacity has given researchers the ability to deconstruct the brain, understand its integral components, its mechanisms of action and how they underpin mental function and behavior,” Lieberman said. “The momentum that has built is almost like Moore’s law with computer chips, (and) you see this increasing power occurring with exponential sort of growth.”

Big Data And Quantum Computers

Posted by in categories: energy, internet, nanotechnology, neuroscience, quantum physics, robotics/AI, singularity, space travel, supercomputing, wearables

Luv the whole beautiful picture of a Big Data Quantum Computing Cloud. And, we’re definitely going to need it for all of our data demands and performance demands when you layer in the future of AI (including robotics), wearables, our ongoing convergence to singularity with nanobots and other BMI technologies. Why we could easily exceed $4.6 bil by 2021.


From gene mapping to space exploration, humanity continues to generate ever-larger sets of data—far more information than people can actually process, manage, or understand.

Machine learning systems can help researchers deal with this ever-growing flood of information. Some of the most powerful of these analytical tools are based on a strange branch of geometry called topology, which deals with properties that stay the same even when something is bent and stretched every which way.

[1601.02970] Deep Neural Networks predict Hierarchical Spatio-temporal Cortical Dynamics of Human Visual Object Recognition

Posted by in categories: neuroscience, robotics/AI

More insights for AI research.


The complex multi-stage architecture of cortical visual pathways provides the neural basis for efficient visual object recognition in humans. However, the stage-wise computations therein remain poorly understood. Here, we compared temporal (magnetoencephalography) and spatial (functional MRI) visual brain representations with representations in an artificial deep neural network (DNN) tuned to the statistics of real-world visual recognition. We showed that the DNN captured the stages of human visual processing in both time and space from early visual areas towards the dorsal and ventral streams. Further investigation of crucial DNN parameters revealed that while model architecture was important, training on real-world categorization was necessary to enforce spatio-temporal hierarchical relationships with the brain. Together our results provide an algorithmically informed view on the spatio-temporal dynamics of visual object recognition in the human visual brain.

Why Morphological Freedom Is a Fantasy: Your Body Isn’t Just Your Own

Posted by in categories: nanotechnology, neuroscience, transhumanism

I must admit some of the information in this article is making me scratch my head a lttle. However, I do believe that many of us who wish to remain relevant in the future (especially in industry and government) will find ourselves requiring a Brain Mind Interface (BMI) of some sort whether it’s an implant or nanobot; folks will find that they have to have one in order to work or function in society.


Transhumanists claim complete freedom to modify their bodies, but that absolutist stance could endanger future generations.

Brain tumor removed without surgery at Apollo hospital

Posted by in categories: biotech/medical, neuroscience

Can you say “amazing” — brain tumor removed without surgery.


The Neurosurgery wing of the Local Apollo hospital here successfully conducted a rare, modern at the same time sensitive method of removal of a brain tumor tissue for diagnosis sending a small needle deep in to the brain without opening the skull and anesthesia. This sophisticated and critical process known as ‘Stereotactic Biopsy was conducted on a 50 year old woman Thalari Chinnammayi, without any complications and with hardly two days of hospitalization. Claiming such Biopsy application as the first of its kind in Coastal Andhra region, Dr M V Kiran Kumar senior consultant Neuro surgeon of Apollo hospital, said it would involve less expenditure and almost risk free and not warrant a repeated biopsy. Presenting the patient before the press persons here today, he said, she was suffering from chronic headache for the past one month and during clinical examination it was found she was having small tumor in the brain that too in a very deep lesion.‘ The tumor in size of 1.5x 2cms was located in the left side of the brain at a place called as Caudate Nucleus. A small piece of brain tissue was removed by performing stereotactic biopsy and during examination it was diagnosed as grade-3 Anaplastic Astrocytoma (cancerous growth). She was referred to Oncologist for treatment either by chemo therapy or Radiation he added. Dr C Suryaprakasarao Medical director of the hospital said that the Neurology department was strengthened by acquiring modern sophisticated equipment besides appointing Dr Kamaraju as a Neuro physician. I. V.V Ramana hospital chief administrator said that they were going to introduce the ‘Deep brain stimulation therapy utilising the expertise of Dr Kiran Kumar. UNI XR/DP KVV AK1935.
