Dietary Supplements Fail to Prevent Prostate Cancer
Two large-scale clinical trials found that regular intake of vitamin E, vitamin C or selenium does not reduce the risk of prostate cancer or other cancers in older men, as some previous studies had suggested.
Compound Helps Detect Cancer Cells in Mice
Researchers have developed an imaging compound that allows them to visualize viable breast cancer cells that have spread to the lungs of mice. Similar compounds may one day help doctors monitor their patient's tumors and even aid in tumor removal.
New Genetic Target for Sickle Cell Disease Therapy
Researchers have identified a gene involved in the inherited blood disorders sickle cell disease and thalassemia. The discovery identifies a potential new target for therapies that could dramatically alter the course of the disorders.

Gene Activity Can Predict Survival Rates of Patients with Lymphoma
A new study shows that gene activity can be used to predict survival rates of people with a type of non-Hodgkin's lymphoma called diffuse large B-cell lymphoma (DLBCL). The method can potentially be used to guide treatment and to help develop future therapies.
Gut Microbiomes Differ Between Obese and Lean People
A new study has found that obese and lean twins have clear differences in their gut microbial communities. The finding points the way for future research into the roles that gut microbes may play in obesity and other health conditions.
Experimental Drug Destroys TB Bacteria From Within
Scientists have discovered how an experimental drug unleashes its destructive force inside the bacteria that cause tuberculosis (TB). The finding could help scientists develop new approaches for combating dormant TB infections, which are especially difficult to treat. The research may ultimately lead to improved drugs against other bacteria as well.
