Bacteria Use Social Networks to Survive

July 22, 2013 11:07 am | Comments

The next time your Facebook stream is filled with cat videos, think about Myxococcus xanthus. The single-cell soil bacterium also uses a social network. Using several imaging techniques, scientists saw for the first time that M. xanthus cells are connected by a network of chain-like membranes.The scientists believe M. xanthus uses its network to quietly transfer proteins and other molecules from one to another.

Nerves Play Key Role in Prostate Cancer

July 12, 2013 10:08 am | Comments

Researchers have found that nerves play a critical role in both the development and spread of prostate tumors. Their findings, using both a mouse model and human prostate tissue, may lead to new ways to predict the aggressiveness of prostate cancer and to novel therapies for preventing and treating the disease.

Potential Cancer Diagnosis Biomarker Identified

July 9, 2013 10:29 am | Comments

Micronuclei, erratic, small extra nuclei, which contain fragments, or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis. In a new study, a team of scientists found that disrupted micronuclei might play an even more active role in carcinogenesis than previously thought.
