Who would dare to pit one fatal disease against another… inside the body of an six-year-old patient? Doctors and researchers in Pennsylvania did just that, and the results were stunning. Using a “dead” version of the HIV virus, they retrained the immune system of a six-year-old Leukemia patient to recognize and then kill tumor cells.
A 65-year-old woman’s brain was cut into 7,400 slices to create the most detailed three-dimensional atlas of the human brain ever made, bringing researchers one step closer to reverse-engineering the brain’s convoluted circuitry.
The atlas creators, who are from Canada and Germany, have made the ultra high-resolution model — 50 times more detailed than a typical scan — publicly available in a free online format. The authors also published their work in the journal Science on Thursday.
The atlas, called BigBrain, offers a common basis for open, worldwide scientific discussion on the brain, said author Karl Zilles of the Heinrich Heine University Düsseldorf.
Stanford researchers developed a retinal prosthesis that wirelessly transmits images from a video camera in a pair of glasses directly to a chip implanted inside the retina tissue. The innovations of lead scientist Daniel Palanker and his colleagues is that their system does away with any cable between the implant and the video eyeglasses, and buries the chip in the sub-retinal layers of the eye instead of on its surface to eliminate a kind of interference. They published their latest breakthroughs in the science journal Nature Communications.
