DNA

Sequencing the DNA of cancer tumors to help pinpoint treatment is an emerging element of precision medicine. While patients and doctors alike want these tests, they often don't benefit patients.

Hundreds of millions of dollars are pouring into research labs in an effort to collect genetic information on a million people. But some skeptics say the focus should be on humans themselves, not DNA.

Bacteria engineered with an expanded genetic alphabet can produce novel proteins, which could lead to the development of new drugs.

The "DNA Discussion Project" brings students, staff and faculty at West Chester University together to learn about their genetic heritage. For some people, the revelations are hard to digest.

In experimental embryos, scientists were able to repair the gene that causes a serious heart disorder. More research is needed to confirm the method would produce healthy babies, they say.
