Roots Of The Lithium Battery Problem
2013-12-18 13:37:01

Lawrence Berkeley National Laboratory The lithium-ion batteries that power our laptops, smartphones and electric vehicles could have significantly higher energy density if their graphite anodes were to be replaced by lithium metal anodes. Hampering this change, however, has been the so-called dendrite problem. Over the course of several battery charge/discharge cycles, particularly when the battery is cycled at a fast rate, microscopic fibers of lithium, called “dendrites,” sprout from...

Neuroscientists Discover New ‘Mini-neural Computer’ In The Brain

University of North Carolina at Chapel Hill School of Medicine Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now researchers at UNC have shown that dendrites actively process information, multiplying the brain’s computing power. The finding could help researchers better understand neurological disorders. Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now...

Dendrites In Brain Act As Mini-Neural Computers

Brett Smith for redOrbit.com - Your Universe Online Initially thought of as a simple means of sending signals in the brain, new research, published on Sunday in the journal Nature, has revealed that the dendrite sections of neurons are capable of processing information. "Suddenly, it's as if the processing power of the brain is much greater than we had originally thought," said study author Spencer Smith, an assistant professor in the UNC School of Medicine. "Imagine you're reverse...

Understanding How Neurons Get Wired

University of Arizona Two different versions of the same signaling protein tell a nerve cell which end is which, UA researchers have discovered. The findings could help improve therapies for spinal injuries and neurodegenerative diseases. University of Arizona scientists have discovered an unknown mechanism that establishes polarity in developing nerve cells. Understanding how nerve cells make connections is an important step in developing cures for nerve damage resulting from spinal...

Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell. The video offers a rare peek at how proteins, the brain's building blocks, are directed through neurons to renew its structure. It can be viewed online here: http://www.youtube.com/watch?v=baI9q2--q7s&feature=youtu.be "Your brain is being disassembled and reassembled every day," said Don...

Korean scientists have used tiny stars, squares and triangles as a toolkit to create live neural circuits in a dish. They hope the shapes can be used to create a reproducible neural circuit model that could be used for learning and memory studies as well as drug screening applications; the shapes could also be integrated into the latest neural tissue scaffolds to aid the regeneration of neurons at injured sites in the body, such as the spinal cord. Published today, 20 July, in IOP...

Max Planck researchers found over 2500 mRNA along dendrites and axons How do we build a memory in the brain? It is well known that for animals (and humans) new proteins are needed to establish long-term memories. During learning information is stored at the synapses, the junctions connecting nerve cells. Synapses also require new proteins in order to show changes in their strength (synaptic plasticity). Historically, scientists have focused on the cell body as the place where the required...

UI researchers explore how one cell binds itself to another, shedding light on neurodevelopmental disorders University of Iowa biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex–the outermost layer of the brain where language, thought and other higher functions take place –disrupts the formation of neural circuitry. Andrew Garrett, former neuroscience...

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites -- the filament-like projections that conduct electrochemical signals between neurons -- and disrupts normal patterns of neuronal connections in the brain. "Dendrite growth and branching during early development is a finely orchestrated process, and the presence of certain PCBs confuses the conductor of that...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
