No Word on How It Will Work for People Who Are Red-Green Colorblind

MIT's Technology Review reports on Katushka, a bright-red fluorescent protein that can be seen from deep within the bodies of small animals, making possible non-invasive, live-cell imaging of disease progression. Developed by researchers at Shemiakin-Ovchinnikov Institute of Bioorganic Chemistry in Moscow, the new protein belongs to the far-infrared spectrum, which will allow it to image tagged genes, cells, or tissues that require deep tissue penetration. Their research was published in Nature Methods.
