Engineered Gut Bacteria Reverse Type 1 Diabetes in Experimental Mice

Scientists have managed to reverse type 1 diabetes (T1D) in experimental mice by giving the animals an oral course of harmless gut bacteria that had been engineered to secrete the whole proinsulin autoantigen (PINS) and the immunomodulatory human cytokine IL-10 (hIL10). An international team led... Read More

Moffitt Cancer Center Researchers Discover How Cancer Cells “Hijack” a Mechanism to Grow

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have discovered a mechanism that explains how some cancer cells “hijack” a biological process to potentially activate cell growth and the survival of cancer gene expression.

Their study appeared in a recen... Read More

Microbes Go Rafting on Floating Volcanic Rocks

Volcanoes bring death and destruction, but out of the ashes life soon finds fertile ground. A unique experiment is sifting through floating debris from an ongoing volcanic event to see how microbes move in. The results may help in assessing a recent hypothesis that the first life forms may have ... Read More
