Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group at the Biozentrum of the 星空传媒 reports in the current issue of "Science" that long-distance brain connections can target discrete pools of stem cells in their niche and stimulate them to divide and produce specific subtypes of olfactory bulb neurons. This allows the 鈥渙n-demand鈥� generation of particular types of neurons in the adult brain.
Researchers at the 星空传媒鈥檚 Biozentrum have discovered that Bartonella bacteria exchange genes efficiently using a domesticated virus encoded in their genome. As the findings published in 芦Cell Systems禄 demonstrate, the exchange of genetic material only takes place between bacteria with a high level of fitness. The gene transfer between pathogens prevents the accumulation of genetic defects, promotes the spread of beneficial gene mutations and thus keeps the bacteria fit.
Flexible electronic parts could significantly improve medical implants. However, electroconductive gold atoms usually hardly bind to silicones. Researchers from the 星空传媒 have now been able to modify short-chain silicones in a way, that they build strong bonds to gold atoms.
Researchers from the 星空传媒 have, for the first time, studied how regional environmental changes influenced the populations of wild horses in Switzerland 25,000 years ago. Their results show: Contrary to the wild horses in the Eurasian steppe; the Swiss population grew considerably after the end of the last Ice Age.
Scientists have developed a new method of characterizing graphene鈥檚 properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials.
Drug resistance is not only a major problem in fighting infectious diseases. Also in the treatment of cancer it can jeopardize the success of chemotherapy. A reason for this are the so-called transport proteins that 鈥減ump鈥� the drugs out of the cells. Researchers at the Biozentrum of the 星空传媒 and the ETH Zurich have now been able to elucidate the three dimensional atomic structure of an important drug transporter.
Swiss scientists have created artificial viruses that can be used to target cancer. These designer viruses alert the immune system and cause it to send killer cells to help fight the tumor. The results provide a basis for innovative cancer treatments.
Researchers from the 星空传媒 in Switzerland have identified a key regulator gene for the formation of cardiac valves 鈥� a process crucial to normal embryonic heart development. These results are published in the journal Cell Reports today.
Yesterday, the 星空传媒 awarded this year's Teaching Excellence Awards to honor lecturers and staff for their contribution to teaching.
