DNA-based vaccine triples survival for dogs with melanoma

The options for treating advanced melanoma are limited – regardless of whether the patient is a dog or a human. Because this deadly cancer is virtually resistant to chemotherapy and radiation in its late stages, new approaches are being investigated including vaccines that harness the immune system. For nine dogs that naturally developed canine malignant melanoma, treatment with a new DNA-based vaccine more than tripled their median survival from an expected 90 days to an average of 389 days.

FBI reports Internet fraud complaints tripled in 2002

UCLA astronomer Andrea Ghez announced more than four years ago that a monstrous black hole resides at the center of our Milky Way galaxy, 24,000 light years away, with a mass more than 2 million times that of our sun. Some astronomers greeted the announcement with skepticism, and proposed exotic forms of matter as alternatives. At the American Association for the Advancement of Science meeting Feb. 16 in Denver, Ghez reported that the case for the black hole has been strengthened substantially, and that all of the proposed alternatives can be excluded.
