Scientists at the University of Michigan Comprehensive Cancer Center have identified a gene that controls the amazing ability of adult stem cells to self-renew, or make new copies of themselves, throughout life.
In a series of extensive cell culture and animal studies, U-M scientists discovered that a gene called Bmi-1 was required for self-renewal in two types of adult stem cells – neural stem cells from the central nervous system and neural crest stem cells from the peripheral nervous system. In a previous study, other U-M scientists found that Bmi-1 also was necessary for continued self-renewal in a third variety of blood-forming or hematopoietic stem cells.
"So far, we and our colleagues have studied three important types of adult stem cells and Bmi-1 appears to work similarly in every case," says Sean Morrison, Ph.D., an assistant professor of internal medicine in the U-M Medical School and a Howard Hughes Medical Institute investigator. "This raises the intriguing possibility that Bmi-1 could be a universal regulator controlling self-renewal in all adult stem cells."

Researchers Discover New Anti-Cancer Protein

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...
