Human and mouse neurons became connected via synapses. Credit: Giovanni Cancemi/Shutterstock.com Think of if lost, deteriorated, or diseased brain parts could be regrown in the laboratory and transplanted for a new lease on life. Scientists at the University of California San Diego have gotten us closer to that fact. Human cortical organoids (or 'mini-brains') transplanted...
The scheme for a mechanism of bubble-detachment. a) Normal flat electrode, b) the problems of adhered bubbles, and c) various approaches for the removal of gas bubbles. In (a), R, ρ, g, and λ indicate the dimension of bubbles, the density of a solution, gravitational acceleration constant, and surface tension of a solution, respectively....
Wake forest medical center Brain electrodes developed to mimic the hippocampus appear to increase the encoding of memories-- and are two times as effective in people with bad memory. A singular form of brain stimulation seems to boost people's capability to remember new details-- by imitating how our brains create memories. Memory prosthesis The "memory prosthesis," which includes...
UConn researchers have developed a way of charging deep brain stimulators that don't require the battery power that's currently standard. Credit: University of Connecticut Implantable deep brain stimulators could aid lots of people with neurological and psychiatric illnesses when conventional therapies stop functioning. Nevertheless, surgery every time the batteries have to be transformed is a...
Researchers developed a "DishBrain" system that associated neurons to a computer running the typical computer game Pong. Within five minutes, the cells commenced "learning" and improved their efficiency. The device of "learning" could entail the free-energy concept, according to which the brain searches for to lessen entropy (unpredictability) in its atmosphere. Recently research announced in...
The distributions and sizes of lithium peroxide on the end surfaces of C-AAO electrodes and inside them. Credit: Prof. TAN Peng's team With a high power density, Li-O2 batteries have become a state-of-the-art battery Innovation. Inside the Li-O2 battery, the generation and disintegration of the discharged product solid lithium peroxide (Li2O2) have a significant impact...
A nanowire compared to a human hair. Poor battery life is the number one issue when it comes to smartphones and laptops. As a wireless society, having to secure ourselves to power up our gadgets seems more and more a nuisance. Furthermore, while scientists are looking into wireless charging, we would have to worry less...
Researchers have developed self-assembled, protein-based circuits that can do simple logic functions in proof-of-concept research. The work demonstrates that it is possible to develop stable digital circuits that benefit from an electron's properties at quantum scales. Molecular circuits One of the stumbling blocks in developing molecular circuits is that the circuits become unreliable as the circuit...
Researchers have carried out experiments on a parabolic flight to examine the efficiency of oxygen-evolving electrolysis on the Moon and Mars. Researchers Bethany Lomax and Gunter Just conducting experiments on a parabolic flight. Credit: Manchester University The discovery from the Universities of Manchester and Glasgow is stated to supply beneficial insights into establishing human habitats far...
DETI mapping results from the brain of a person viewing one of the stimuli used in the experiment (far left). The central column shows a flattened topographical map of the electrodes over the back of the head, illustrating the variation of DETI maps at each electrode across that scalp region. On the right-hand side,...
