XMM-Newton digs into the secrets of fossil galaxy clusters
Taking advantage of the high sensitivity of ESA's XMM-Newton and the sharp vision of NASA's Chandra X-Ray space observatories, astronomers have studied the behaviour of massive fossil galaxy clusters, trying to find out how they find the time to form.

Almost 1/3 of colon cancer patients stop chemotherapy, leading to double the death rate
New research from Columbia University Medical Center has found that as many as 30 percent of patients with stage III colon cancer who were prescribed six months of chemotherapy stopped their treatment prematurely.

The promise of a B-cell biologic therapy for rheumatoid arthritis
The results of a study featured in the May 2006 issue of Arthritis & Rheumatism, indicate the promise of low-dose rituximab to achieve remission for RA patients, without serious side effects and without the need for prescribing harsh steroids.

NIST gears up to evaluate short range 3-D imaging
Researchers at the National Institute of Standards and Technology (NIST) recently established an indoor, artifact-based facility to create new test protocols and performance measures to evaluate 3-D imaging systems used for measurment and inspection in the manufacturing, construction and transportation sectors.

New study to address HIV-related deaths in Downtown Eastside

Choice of chemotherapy before liver metastasis surgery matters for some patients
Patients and their physicians should be careful when selecting a chemotherapy drug to treat colorectal cancer that has spread to the liver, say researchers at The University of Texas M.

New insights into the impact of injury on cartilage cells
In the May 2006 issue of Arthritis & Rheumatism, researchers present the results of a study to test the hypothesis that leukocytes extend the zone of damage and cell death in cartilage after an acute injury.
