A protein that influences the epigenetic characteristics of tumor cells is directly linked to the grade of malignancy of prostate cancer. This key discovery has been made by a team of scientists from the University of Zurich, German Cancer Research Center (DKFZ), Hamburg-Eppendorf University Hospital, Heidelberg University, and other institutes in a study of 7,700 samples of tumor tissue. The detection of this biomarker may serve as an indicator of the likelihood that the disease may take an aggressive course, and may thus be helpful in choosing an appropriate treatment.
ETH Zurich and the University of Zurich are founding a new translational research centre at the interface of medicine, science and engineering: the Wyss Translational Center Zurich. A USD 120 million donation from Dr. h.c. mult. Hansjörg Wyss to the two Zurich universities is making this possible. Through an interdisciplinary approach, the new centre aims to accelerate the development and application of innovative medical therapies and groundbreaking robotic systems.
Dec 10, 2014 Anyone who is good at German learns English better
Your literacy skills in your first language heavily influence the learning of a foreign language. Thus, anyone who reads and writes German well is likely to transfer this advantage to English – regardless of the age of onset of foreign language learning. Foreign language lessons at an early age, however, pay off less than was previously assumed. In fact, they can even have a negative impact on the first language in the short run, as a linguist from the University of Zurich reveals in her long-term study involving 200 Zurich high-school children.
In cell competition the strong eliminate the weak, thereby ensuring optimal tissue fitness. Molecular biologists at the University of Zurich and Columbia University have now demonstrated that the innate immune system plays a key role in this important mechanism. However, cancer cells also make use of this: they can cause cells that are important for healthy tissue to die.
With over 30,000 species worldwide, the ray fins are currently the largest group of fish. These bony fish were not always as numerous, however. Losses of other fish species, such as cartilaginous fish, helped them to spread successfully. As paleontologists from the University of Zurich together with international researchers reveal, a series of serious extinction events between 300 to 200 million years ago played a central role in the development of today’s fish fauna.
Nov 26, 2014 DNA survives critical entry into Earth’s atmosphere
The genetic material DNA can survive a flight through space and re-entry into the earth’s atmosphere – and still pass on genetic information. A team of scientists from UZH obtained these astonishing results during an experiment on the TEXUS-49 research rocket mission.
Nov 26, 2014 How various brain areas interact in decisions
Our decisions can be pictured in the brain. Scientists at the University of Zurich were able to show in a recent study which areas are most active in decision making. Often the so-called prefrontal cortex not only apparently shows increased activity during decisions that require self-control, but in general during decision making. The results could be of use in promoting decision skills in difficult decisions.
