Devising Nano Vision for an Optical Microscope

...ensable imaging and measurement tool well into the expanding realm of nanotechnology. Called phase-sensitive, scatter-field optical imaging, the computer-intensive technique under development at NIST uses a set of dynamically engineered light waves optimized for particular properties (such as angular orientat...

Genome-wide mouse study yields link to human leukemia

...oes through a pre-leukemic stage marked by rapidly expanding T cells and natural killer cells, both major components of the immune system. In comparing the mice in the pre-leukemic stage and those with ALL with normal mice, researchers found that methylation, a chemical process that adds methyl molecules to D...

Jump-starting T Cells In Skin Cancer

...proteins sometimes causes tumor regression without expanding large numbers of vaccine-specific killer T cells. Pierre Coulie's group studied anti-tumor T cells in patients vaccinated with a tumor antigen called MAGE-3. In one patient whose tumor regressed after vaccination, the authors found significantly mor...
