09-10-2007 · EurekAlert!
Nearly 30 years after Nobel laureate Linus Pauling famously and controversially suggested that vitamin C supplements can prevent cancer, a team of Johns Hopkins scientists have shown that in mice, at least, vitamin C -- and potentially other antioxidants -- can indeed inhibit the growth of some tumors, just not in the manner suggested by years of investigation.

- Researchers find gene linked to Crohn's disease
10-26-2006 · EurekAlert!
An international team of researchers has identified another gene mutation linked to the inflammatory bowel diseases (IBD) Crohn's disease and ulcerative colitis. The team, including Johns Hopkins gastroenterologists and geneticists, says the novel mutation is in the interleukin-23 (IL-23) gene receptor present in healthy people without Crohn's disease but rare in those with the disease.

- The first 3-D map of the universe
03-03-2007 · EurekAlert!
An International team of scientists from CNRS (France), CEA, (France) and Caltec (USA) made the first 3-D map of dark matter in the universe using gravitational lensing effects. The team analyzed the Cosmos field, the largest field of galaxies ever observed with the Hubble space telescope. This study can be found in the Jan. 7, 2007, issue of Nature.

- Old idea spawns new way to study dark matter
05-30-2007 · EurekAlert!
An international team of astronomers led by Ohio State University has examined dark matter in the outer reaches of our galaxy in a new way. For the first time, they were able to employ triangulation -- a method rooted in ancient Greek geometry -- to estimate the location of dark matter and calculate its mass.
