How can humans and chimpanzees, who share about 99 percent of the same genes be so different? Scientists in the United States and Australia say changes in the gene expression, not just genes, is a big part of what separates humans from their nearest relatives.
Why can one person smoke with no apparent ill-effects while another gets lung cancer? Why does one identical twin get Alzheimer's when his brother does not?
Breast cancer patients could find out whether they will respond positively to chemotherapy treatment by testing for the activity of certain genes.
Using newly available biological technology, researchers have developed the first molecular portrait of multiple gene activity in diseased heart tissue taken from dogs near death from a devastating disease. The discovery sheds new light on the heart's response to dilated cardiomyopathy (DCM), a disease of large-breed dogs.
Just as the printing press revolutionized the creation of reading matter, a "nano-printing" technique developed at MIT could enable the mass production of nano-devices currently built one at a time.
