Memristor can do multistate processing as well as nonvolatile memory

Posted by in categories: computing, nanotechnology, neuroscience, quantum physics

Nice; ReRam with multi-state processing and reliable storage.


Short of full blown molecular computers or universal quantum computers or optical computers memristors have the most potential for a hardware change to dramatically boost the power and capabilities of computers. The boost to computer power could be nearly a million times by fully leveraging memristors. It would likely be more like a thousand times with more near to mid term usage of memristors.

Memristors (aka ReRAM) could become computer memory that is over 10 times denser than Flash or DRAM in two dimensions. Memristors like flash would be nonvolatile memory that would not need power for retain memory. Memristors are created from nanowire lattices which could be stacked in three dimensions. Memristors have also previously been shown to behave like brain synapses which could be used for computer architectures that emulate the human brain for neuromorphic computing. Now there is work on multistate memristors that perform computation. This means that eventually processing and memory could be tightly integrated.

Mapping brain in preemies may predict later disability

Posted by in categories: biotech/medical, neuroscience

MINNEAPOLIS — Scanning a premature infant’s brain shortly after birth to map the location and volume of lesions, small areas of injury in the brain’s white matter, may help doctors better predict whether the baby will have disabilities later, according to a new study published in the January 18, 2017, online issue of Neurology ®, the medical journal of the American Academy of Neurology.

According to the Centers for Disease Control and Prevention, one in 10 babies is born prematurely in the United States.

Lack of oxygen to the brain is the most common form of brain injury in premature infants, resulting in damage to the white matter. White matter contains nerve fibers that maintain contact between various parts of the brain. Damage to white matter can interfere with communication in the brain and the signals it sends to other parts of the body.

Human organs-on-chips: Harvard develops microchips lined with living cells to revolutionise medicine

Posted by in categories: biotech/medical, computing, engineering, neuroscience

Biological engineers at Harvard University’s Wyss Institute for Biologically Inspired Engineering have invented a microchip that can be lined with living human cells in order to revolutionise medicine, particularly relating to drug testing, disease modelling and personalised medicine.

The ‘human organs-on-chip’ is a microchip made from a clear flexible polymer that contains hollow microfluidic channels that are lined with living human cells, together with an interface that lines the interior surface of blood vessels and lymphatic vessels, known as an endothelium.

The idea is that the microchip can emulate the microarchitecture and functions of multiple human organs such as the lungs, kidneys, skin, bone marrow, intestines and blood-brain barrier. And if you were able to do this, you could then test out drugs and study how diseases affect the body without having to endanger human patients, or waste precious organs needed for transplants.

Protein Associated With Parkinson’s Travels From Brain To Gut

Posted by in categories: biotech/medical, neuroscience

Pretty wild.


Researchers of the German Center for Neurodegenerative Diseases (DZNE) have found that “alpha-synuclein,” a protein involved in a series of neurological disorders including Parkinson’s disease, is capable of travelling from brain to stomach and that it does so following a specific pathway. Donato Di Monte and co-workers report on this in the journal Acta Neuropathologica. Their study, carried out in rats, sheds new light on pathological processes that could underlie disease progression in humans.

Alpha-synuclein occurs naturally in the nervous system, where it plays an important role in synaptic function. However, in Parkinson’s disease, dementia with Lewy bodies and other neurodegenerative diseases termed “synucleinopathies,” this protein is accumulated within neurons, forming pathological aggregates. Distinct areas of the brain become progressively affected by this condition. The specific mechanisms and pathways involved in this widespread distribution of alpha-synuclein pathology remain to be fully elucidated. Clinical and experimental evidence suggests however that alpha-synuclein — or abnormal forms of it — could “jump” from one neuron to another and thus spread between anatomically interconnected regions.

‘5-D protein fingerprinting’ with nanopores could give insights into Alzheimer’s, Parkinson’s

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

Nice.


In research that could one day lead to advances against neurodegenerative diseases like Alzheimer’s and Parkinson’s, University of Michigan engineering researchers have demonstrated a technique for precisely measuring the properties of individual protein molecules floating in a liquid.

Proteins are essential to the function of every cell. Measuring their properties in blood and other body fluids could unlock valuable information, as the molecules are a vital building block in the body. The body manufactures them in a variety of complex shapes that can transmit messages between cells, carry oxygen and perform other important functions.

Older, fitter adults experience greater brain activity while learning

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

Exercise is one of the best ways to slow down aging and its free too!


(Boston) — Older adults who experience good cardiac fitness may be also keeping their brains in good shape as well.

In what is believed to be the first study of its kind, older adults who scored high on cardiorespiratory fitness (CRF) tests performed better on memory tasks than those who had low CRF. Further, the more fit older adults were, the more active their brain was during learning. These findings appear in the journal Cortex. Difficulty remembering new information represents one of the most common complaints in aging and decreased memory performance is one of the hallmark impairments in Alzheimer’s disease.

Could you recruit a ‘mind reader’ for Facebook?

Posted by in categories: computing, neuroscience

Many who worked closely with me at Microsoft use to say I had a Crystal ball and was psychic; maybe I have met my match for a career — LOL.


A number of job adverts suggest that Facebook is taking social networking to a different level of science fiction.

The social networking giant has advertised for a Haptics Engineer, a Neural Imaging Engineer, a Signal Processing Engineer and a Brain-Computer Interface (BCI) Engineer – leading people to think Facebook is working on mind reading technology.
