Surgical Robot 'Scrubs In' At UNC, May Be More Precise Than Conventional Surgery

...ment is similar to open surgery, with "all-around" vision and the ability to zoom in and out. Another advantage with da Vinci is the elimination of tremor. Surgeons can scale, or ratio, their finger movement to that of the robotic instrument. A movement of inches at the console can be scaled down to centim...

NHGRI expands effort to revolutionize sequencing technologies

...e to common, complex diseases. Ultimately, NHGRI's vision is to cut the cost of whole-genome sequencing to $1,000 or less, which will enable the sequencing of individual genomes as part of routine medical care. The ability to sequence an individual genome cost-effectively could enable health care profession...

Scientists map one of biology's critical light-sensing structures

...ically speaking, we can now try to re-engineer the vision system of a plant." According to Vierstra, there are many kinds of phytochromes found in every plant, and they exist in virtually all cells. They occur in greater concentrations in cells that respond directly to light, such as in root tips and new s...

PET imaging reveals the immune system at work

...Angeles has taken a key step toward realizing that vision by demonstrating the ability to peer inside the body non-invasively and see the immune system at work. The new research is important because it may one day aid physicians in the diagnosis and treatment of important conditions such as cancer and othe...
