Researchers at the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Centre have reached an early, but important, milestone in the quest to grow replacement livers in the lab. They are the first to use human liver cells to successfully engineer miniature livers that function - at least in a laboratory setting - like human livers. The next step is to see if the livers will continue to function after transplantation in an animal model…
An international team of Mycologists and Ecologists studying Atlantic sea turtles at Cape Verde have discovered that the species is under threat from a fungal infection which targets eggs. The research, published in FEMS Microbiology Letters, reveals how the fungus Fusarium solani may have played a key role in the 30-year decline in turtle numbers…
Researchers led by Vanderbilt's Roger Cone, Ph.D., have discovered a new member of a gene family that has powerful influences on pigmentation and the regulation of body weight…
When the space shuttle Discovery lifts off on its final flight Nov. 2, its six astronauts will be joined by 16 rodent passengers on a historic mission of their own…
A new study by University of North Carolina at Chapel Hill and Norwegian researchers has found that women with anorexia nervosa are much more likely to have both unplanned pregnancies and induced abortions than women who don't have the serious eating disorder…
Saving a soldier's life takes precedence over treating traumatic urologic injuries on the battlefield, a Medical College of Georgia researcher says…
Women with dense breasts and no lobular involution were at a higher risk for developing breast cancer than those with non-dense breasts and complete involution, according to a study published online in The Journal of the National Cancer Institute…
For pancreatic cancer patients unable to undergo surgery - the only known cure for this form of cancer - a highly targeted cancer radiation therapy may help slow cancer progression and lessen disease symptoms, according to researchers at Henry Ford Hospital in Detroit…
Scientists of the Max Delbrueck Centre for Molecular Medicine (MDC) Berlin-Buch and the Experimental and Clinical Research Centre (ECRC) of MDC and Charite in Berlin-Buch have gained new insights into the development of epithelial cells and their molecular repertoire. Dr Max Werth, Katharina Walentin and Professor Kai Schmidt-Ott have identified a transcription factor (grainyhead-like 2, Grhl2), which regulates the composition of the molecular 'bridges' that link adjacent epithelial cells. The authors were able to demonstrate that Grhl2, via DNA-binding, directly regulates the expression of two such cell junctional molecules, E-cadherin and claudin 4 (Development, doi:10.1242/dev.055483)…
The change in the ice mass covering Antarctica is a critical factor in global climate events. Scientists at the GFZ German Research Centre for Geosciences have now found that the year by year mass variations in the western Antarctic are mainly attributable to fluctuations in precipitation, which are controlled significantly by the climate phenomenon El Nino. They examined the GFZ data of the German-American satellite mission GRACE (Gravity Recovery and Climate Experiment). The investigation showed significant regional differences in the western coastal area of the South Pole area…
