International human genome sequencing consortium describes finished human genome sequence
...Access to uninterrupted stretches of sequenced DNA can
greatly assist researchers hunting for genes and the neighboring DNA sequences that may regulate their activity, dramatically cutting the effort and expense required to find regions of the human genome that may contain small and often rare variants i...

Molecular mechanism sheds light on neurodegenerative diseases
...f idle and damaged proteins remain, their presence can
affect cell behavior. Misfolded and damaged proteins are common to all human neurodegenerative diseases. They clump together to form toxic aggregates that destroy cell function and cause disease. Morimoto's team is the first to demonstrate in living...

New genomic method can identify disease-causing genes
...mouse genome is similar to that of humans and mice can
be genetically manipulated. Because of this, the mouse is the most commonly used experimental model for studying human disease, and the "mouse to man" approach is widely used. Since analyses of mouse genetic models by traditional methods are very tim...
