Researchers from the University of Pittsburgh Medical Center have made significant progress in identifying the first susceptibility gene for clinical depression, the second leading cause of disability worldwide, possibly providing an important step toward changing the way doctors diagnose and treat major depression that affects nearly 10 percent of the population.
Research results, which were accepted for rapid publication and published today in the American Journal of Medical Genetics, show significant evidence for linkage of unipolar mood disorders to a specific region of chromosome 2q33-35 in women. The findings suggest that a gene in this region contributes to the vulnerability of women in families afflicted with recurrent, early onset major depressive disorder (RE-MDD), to developing mood disorders of varying severity. Men with the same genetic background did not have any more chance of developing mood disorders than normal.
"We have narrowed our search for a susceptibility locus for clinical depression to a small region of chromosome 2 that constitutes only 0.01% of the human genome," said lead author George S. Zubenko, M.D., Ph.D., professor of psychiatry at the University of Pittsburgh School of Medicine and adjunct professor of biological sciences at Carnegie Mellon University. "These results confirm our earlier findings this year that the susceptibility gene in this region selectively affects the vulnerability of women, but not men, to developing severe depression."

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
