"Colours are represented and processed in the same way in the brains of different people. A pair of researchers were able to predict which colours a group of people were looking at using a machine learning tool that was trained on the brain scans of a separate group who had been shown various colours. The duo also found that different colours are processed by subtly different areas within the same brain region, and that different cells responded more strongly to particular colours than others."
"CRISPR-edited pancreas cells implanted into a person with type 1 diabetes have pumped out sugar-regulating insulin for several months without triggering an immune response. The procedure used cells from a deceased donor who did not have diabetes that had been edited to disable two genes that would flag them to the recipient's immune system as foreign. Whether the treatment could remove a person's dependence on injected insulin entirely is unclear, but the demonstration of cell therapy without the need for immunosuppressants is "a major milestone", says endocrinologist Tim Kieffer."
Brain imaging shows that colours are represented and processed in similar cortical regions across different people, with subtle spatial distinctions for particular hues and cells showing preference for specific colours. A machine-learning model trained on one group's brain scans successfully predicted which colours another group viewed. CRISPR-edited pancreatic cells from a deceased donor produced insulin in a person with type 1 diabetes for months without provoking an immune response after two immune-flagging genes were disabled. A genetically modified pig kidney survived in a human for over six months, and warming waters threaten a vital phytoplankton species with potentially severe ecological consequences.
