Holographic acoustic device precisely targets diseased neurons in brain
Non-invasive wearable device uses focused ultrasound to open genetically selected ion channels
How the brain turns waves of light into experiences of color
Brain-cell circuitry allows creatures to see wavelengths of light as information-rich hues
New model for human neocortex: single-direction, not looped
Similar to many artificial neural networks
New microscopy technique reveals activity of one million neurons across the mouse brain
A 100-fold increase in the number of neurons that could be simultaneously recorded
First 3D-printed brain tissue to grow and function like typical brain tissue
Horizontal printing, grown from induced pluripotent stem cells
Physical neural network learns and remembers ‘on the fly’ like neurons for low-energy machine intelligence
Neuromorphic nanowire networks outperfom conventional artificial neural networks, avoiding heavy memory and energy usage
Scientists build tiny healing biological robots from human cells
Future healing uses may include clearing arterial plaque, repairing spinal cord or retinal nerve damage, and targeting bacteria or cancer cells
Future soft optical fibers could allow for exploring new treatments to block peripheral nerve pain
MIT engineers use optogenetics to test future soft, stretchable optical fibers
Blue light exposure can damage neuronal function and induce aging
Daily low-intensity blue-light exposure—similar to that experienced daily by billions of humans in the form of LED lighting and device screens—changed flies at the sub-cellular level, affecting processes related to aging and circadian rhythms
Transparent brain-computer interface can read deep neural activity from the surface
A minimally invasive BCI, unlike Neuralink and other approaches
