... kids." So she and her colleagues are constructing sections of the Tree that allow the public to contribute and to use the information. "Right now we work with teachers, and we're starting to do family registration." A special section of the Web site, called Treehouses, is written by members of the public.

...neurodegenerative diseases involve staining tissue sections to reveal the location of the iron, or extracting the particles. But these approaches reveal neither the specific iron compounds present nor the relationship of those compounds to specific structures within the tissue.

Examination of thin tissue sections of the developing ureters from the mutant mice showed a deficiency of smooth muscle, a feature thought to be involved in functional obstruction in humans.

...DNA mutations of single genes or deletion of large sections of the chromosome. However more recently it has become clear that gene silencing in cancer can also occur, in the absence of changes to the DNA sequence: a phenomenon known as 'epigenetics'.
