Call it mindwriting.
The combination of mental effort and state-of-the-art technology have allowed a man with immobilized limbs to communicate by text at speeds rivaling those achieved by his able-bodied peers texting on a smartphone.
Stanford University investigators have coupled artificial-intelligence software with a device, called a brain-computer interface, implanted in the brain of a man with full-body paralysis. The software was able to decode information from the BCI to quickly convert the man s thoughts about handwriting into text on a computer screen.
The man was able to write using this approach more than twice as quickly as he could using a previous method developed by the Stanford researchers, who reported those findings in 2017 in the journal eLife.

Researchers from the Carl R. Woese Institute for Genomic Biology in collaboration with scientists at Oxford University have published a paper in
Cell reporting the function of LanCL proteins. These proteins are found in eukaryotic cells but their function was previously unknown. The study is the first step towards understanding the importance of these ubiquitous proteins.
Bacteria contain enzymes called LanC that are capable of producing small proteins called lanthipeptides, which are characterized by the addition of a thiol group to a modified serine or threonine amino acid. Similar proteins called LanC-like or LanCL have been found in different eukaryotic cells for decades, but their function was unknown.
A new theory for what’s happening in the brain when something looks familiar This novel concept from the lab of neuroscientist Nicole Rust brings the field one step closer to understanding how memory functions. Long-term, it could have implications for treating memory-impairing diseases like Alzheimer’s. How can the brain distinguish between something new and something familiar? Research from the Visual Memory Lab led by Nicole Rust has a new theory, replacing one long-held by the field. (Image: Julia Kuhl)
When a person views a familiar image, even having seen it just once before for a few seconds, something unique happens in the human brain.
