Jump-starting T Cells In Skin Cancer Advanced melanoma, the most deadly form of skin cancer, can be successfully treated in some cases by vaccinating patients with tumor proteins. How these vaccines work and why they are only effective in some patients remains unclear. Pierre Coulie and colleagues now show, in two articles in the January 17 issue of the Journal of Experimental Medicine, that these vaccines work by increasing the number of immune cells called killer T cells that can attack the tumor. In an unexpected finding, however, they discovered that that these cells mostly recognize tumor proteins that were not contained in the vaccine.

New Brain Tumor Model Developed A collaboration of researchers, led by Dr. Martine Roussel (St. Jude Children's Research Hospital), has developed a novel mouse model of medulloblastoma -- the most prevalent malignant pediatric brain tumor -- that the researchers hope will more accurately represent the genetic changes involved in human brain tumor development. Object Recognition Improves When Other Objects Appear In The Same Orie A rose by any other name may smell just as sweet, but tilt it at an unexpected angle and it may still be easy to smell, just not recognize. That is, unless you saw another object -- even an unrelated one -- presented at the same angle.

Silenced Gene Suggests Greater Risk, Possible Marker For African-Ameri Among African-Americans with prostate cancer, a tumor-suppressing gene called GSTP1 is inactivated at a rate 3.5 times higher than among Caucasians, according to a study conducted at the San Francisco VA Medical Center (SFVAMC). New brain scan better detects earliest signs of Alzheimer's disease in A new type of brain scan, called diffusion tensor imaging, appears to be better at detecting whether a person with memory loss might have brain changes of Alzheimer's disease, according to a new study. New Method Provides Better Earthquake Warnings A new method of stress analysis in earthquake research has been developed by FOI, the Swedish Defense Research Agency. Rock Hounds Sleuth Rise Of Earth's Atmosphere "CSI-like"techniques, used on minerals, are revealing the steps that led to evolution of the atmosphere on Earth. President of the Mineralogical Society of America, Douglas Rumble, III, of the Carnegie Institution's Geophysical Laboratory, describes the suite of techniques and studies over the last five years that have led to a growing consensus by the scientific community of what happened to produce the protective ozone layer and atmosphere on our planet.
