Stem-cell approach shows promise for Duchenne muscular dystrophy
Researchers have shown that transplanting stem cells derived from normal mouse blood vessels into the hearts of mice that model the pathology associated with Duchenne muscular dystrophy (DMD) prevents the decrease in heart function associated with DMD. Their findings appear in the journal Stem Cells Translational Medicine. Duchenne muscular dystrophy is a genetic disorder caused by a mutation in the gene for dystrophin, a protein that anchors muscle cells in place when they contract. Without...

Surprising global species shake-up discovered
The diversity of the world's life forms — from corals to carnivores — is under assault. Decades of scientific studies document the fraying of ecosystems and a grim tally of species extinctions due to destroyed habitat, pollution, climate change, invasives and overharvesting. Which makes a recent report in the journal Science rather surprising. Nick Gotelli, a professor at the University of Vermont, with colleagues from Saint Andrews University, Scotland, and the University of Maine,...

Great Barrier Reef marine reserves combat coral disease
A new and significant role for marine reserves on the Great Barrier Reef has been revealed, with researchers finding the reserves reduce the prevalence of coral diseases. It's been known for some time that marine reserves are important for maintaining and enhancing fish stocks, but this is the first time marine reserves have been shown to enhance coral health on the Great Barrier Reef. Researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University found that...

Rapid plankton growth in ocean seen as sign of carbon dioxide loading
A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found. What these findings mean remains to be seen, however, as does whether the rapid growth in the tiny plankton's population is good or bad news for the planet. Published Thursday in the journal Science, the study details a tenfold...

Scientists discover protein's starring role in genome stability, and possibly cancer prevention
If you have a soft spot for unsung heroes, you'll love a DNA repair protein called XPG. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) discovered that XPG plays a previously unknown and critical role helping to maintain genome stability in human cells. Their findings also raise the possibility that the protein helps prevent breast, ovarian, and other cancers associated with defective BRCA genes. The research, which is published online Jan....
