Exact Sciences stock plunged more than 20% late Thursday morning based on what was ostensibly positive early news about a massive pivotal study for the company's colorectal cancer molecular diagnostic test. While the data met all endpoints, investors clearly wanted better and they punished the company as a result.
Technology behind DVD players (does anyone use those any more?) is gaining a second life as the basis for an inexpensive HIV diagnostic test.
Work is under way on a diagnostic test that would determine the response of a patient with advanced breast cancer to drug treatment, by measuring the DNA that breaks off from dying tumor cells into the bloodstream.
Researchers at the U.K.'s University of Cambridge are developing a way to alter DNA in such a way that would allow certain drugs to pass through cell membranes without a hitch.
Huntington's disease patients may be far better served by a new diagnostic that uses a form of polymerase chain reaction technology, researchers in Utah have found. Equally significant, the diagnostic could give quicker results and eliminate the need for additional testing because of inaccuracies.
Using a DNA vaccine could one day be as easy as applying a temporary tattoo, according to U.S. research published in Nature Materials .
Researchers have pinpointed mutations in melanoma tumors in a part of the cancer genome where mutations previously have never been found, marking a milestone in how the basic science of this deadly type of cancer is understood.
Researchers in Texas have come up with a device that's essentially an adaptable diagnostic tool. How so? It can measure 50 different things at once from a single blood drop.
Using microscopic polymer particles gets the DNA inside the cells without the issues of viral delivery, and changing the shapes of the nanoparticles alters how they travel through the body, according to research from Johns Hopkins and Northwestern universities.
In a small study, an experimental therapeutic cervical cancer vaccine developed by Inovio Pharmaceuticals appeared to spur a surge in T cells, leading the investigators to claim a breakthrough on DNA vaccines.
