High levels of immunosuppressant may lead to tumor recurrence

Research finds that high cyclosporine levels are associated with increased risk of hepatocellular carcinoma (HCC) recurrence after liver transplantation. The study suggests tailoring immunosuppressive schedules to individual patients based on their tumor biology, and recommends minimizing exposure to cyclosporine to prevent recurrence.

Method holds promise in identifying markers of non-metastatic vs. metastatic breast cancer

A new study using microarray technology has identified genes that distinguish between non-metastatic and highly metastatic breast cancer tumors. The research, led by Dr. David Tarin, used cell lines with varying capabilities to spread to distant organs and found that several genes were altered in expression patterns between the two typ...

Living metals

A research team from the Max Planck Institute for Metals Research and ESRF observes temporal structural fluctuations on an atomic scale in a crystalline material. The discovery sheds light on how materials respond to external perturbations like changes in temperature, pressure, magnetic or electric fields.

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

A new microbial fuel cell process can produce high yields of hydrogen from biodegradable organic matter in wastewater. This technology uses a small amount of electricity to boost bacterial fermentation, overcoming the 'fermentation barrier' and producing clean hydrogen gas while simultaneously cleaning the wastewater.
