While promising the possibility of hardier crops and a larger, more robust food supply for the world, worries continue over the effect genetically engineered plants might have on the environment. One fear is over the movement of altered genes from domesticated populations to the wild and the effect of these “escaped” genes on ecosystems. In a study published in the December issue of Ecological Applications, Charity Cummings (University of Kansas), Helen Alexander (University of Kansas), Allison Snow
An experimental drug designed to cut off a tumors blood supply showed promising results in patients with advanced colorectal cancer when paired with standard chemotherapy, according to a UCLA Jonsson Cancer Center study published in the Jan. 1 issue of the Journal of Clinical Oncology.
The results of this and subsequent studies of the experimental drug Avastin could change the way oncologists treat patients with this devastating form of cancer, said Dr. Fairooz Kabbinavar, a Jonsson C
A beer a day may help keep heart attacks away, according to a group of Israeli researchers. In preliminary clinical studies of a group of men with coronary artery disease, the researchers showed that drinking one beer (12 ounces) a day for a month produced changes in blood chemistry that are associated with a reduced risk of heart attack.
Their study adds to growing evidence that moderate alcohol consumption may reduce the risk of heart disease, the number one killer in the United States. T
For newly diagnosed multiple myeloma; Previously scorned thalidomide gives new option for patients with difficult-to-treat cancer
A recent study conducted at The University of Texas M. D. Anderson Cancer Center shows that patients with multiple myeloma, a cancer of the bone marrow, were more likely to achieve remission when treated with a combination of drugs that included thalidomide, a medicine that had previously been shelved for causing birth defects.

When members of two species compete directly with each other, scientists believe the one that rolls with the evolutionary punches and adapts most quickly has the upper hand. But new evidence suggests that in relationships that benefit both species, the one that evolves more slowly has the advantage.
“The idea that has been dominant for the last couple of decades is that when two species co-evolve, they try to outrun each other,” said Carl Bergstrom, a University of Washington assistant zoolo
Researchers at the University of California, San Diego (UCSD) School of Medicine have determined the molecular machinery that triggers normal cardiac muscle growth and survival, and have linked defects in this complex to an inherited form of human cardiomyopathy, a type of heart failure where an enlarged heart loses its ability to pump blood.
Published in the December 27, 2002 issue of the journal Cell, the study also identifies a subset of German cardiomyopathy patients with a specific gene
