Advances in neurosurgery have opened the operating room door for an amazing array of highly invasive forms of brain surgery, but doctors and patients still face an incredibly important decision - whether to operate when life-saving surgery could irrevocably damage a patients ability to speak, read or even comprehend a simple conversation.

Improved techniques for the mapping of the brains language areas using functional magnetic resonance imaging (top) may replace much more invasive pre-surgery mapping techniques, such as electrocortical stimulation (bottom), which requires a patient to be awake and conversant while surgeons probe exposed brain areas in an effort to locate and map language-related functions.
Advances in fMRI brain mapping techniques provide neurosurgery teams with valuable information on the location of a patients language functions well before surgery begins, making pre-surgery testing more effective and improving odds of safer brain surgeries.
Now, researchers at Washington University in St. Louis are developing a painless, non-invasive imaging technique that surgeons here already are using to better evaluate brain surgery risks and to more precisely guide operations so that damage to sensitive language areas is avoided.
The breakthrough holds the promise of safer surgeries for the nearly 200,000 Americans diagnosed with brain tumors each year. It also may significantly improve odds of success in an increasingly common epilepsy surgery in which large damaged sections of a patients temporal brain lobe are removed in an effort to alleviate severe seizures.

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...
