MIT model helps researchers 'see' brain development

...t step in analyzing these images is to align their common anatomical structures, such as the “central sulcus,?a fold that separates the motor cortex from the somatosensory cortex.

'Guardian of the genome' protein found to underlie skin tanning

... implications of the research go beyond tanning. A common skin condition, especially among the elderly, is the development of small, dark spots that are unrelated to sun exposure. The spots arise when groups of cells begin producing pigment in response to repeated stress or irritation of the skin. Although ...
