Metabolomics Links Compounds to Prostate Cancer
A new study has uncovered a molecule associated with the transformation of benign prostate tissue into metastatic prostate cancer. The discovery identifies a potentially useful indicator for the disease and suggests new targets for prostate cancer treatments.
How Ozone Harms Lungs
Researchers have discovered why ozone, a common urban air pollutant, causes airway irritation and wheezing. The finding suggests new targets for medications to treat people suffering from wheezing, coughing and shortness of breath.
New Mediator of Bone Breakdown Discovered
Scientists have discovered a lipid mediator in blood that plays a key role in maintaining the balance between the build-up and breakdown of bone. Targeting this mediator may prove useful for treating bone degenerative diseases such as osteoporosis and rheumatoid arthritis.

Brain's Support Cells Influence Sleep
Astrocytes, a type of support cell in the brain, may play an important role in influencing sleep, according to a study in mice. The results suggest a new approach for developing treatments for sleep disorders.
Innate Immune Cells Have Some Memory
A new study of an oft-neglected arm of the immune system may cause researchers to rethink how it helps defend the body from infection.
New Telomerase Protein Discovered
Scientists have discovered a novel part of the telomerase enzyme that helps it reach the ends of chromosomes, where it adds protective DNA sequences called telomeres. The finding suggests a promising new target for anti-tumor therapies.
