Apr 8, 2015 New Technology Making Drones Safer and Smarter
Researchers at the University of Zurich have unveiled new technology enabling drones to recover stable flight from any position and land autonomously in failure situations. It will even be possible to launch drones by simply tossing them into the air like a baseball or recover stable flight after a system failure. Drones will be safer and smarter, with the ability to identify safe landing sites and land automatically when necessary.
Cancer researchers from the University of Zurich have identified a key signaling pathway in B-cell lymphoma, a malignant type of blood cancer. They demonstrate that the signaling path-way can be blocked using compounds that are already in clinical development. This finding might be extremely important for the diagnosis, prognosis and treatment of this disease in the future.
Apr 1, 2015 Poses of power are less powerful than we thought
Legs apart, chest thrust forward, shoulders back: these “power poses” are supposed to influence hormone production and willingness to take on risk in accordance with a study that attained global attention. Scientists from the University of Zurich, however, found no support for these assumptions in a large study. “Power poses” do not influence behavior, but they might allow someone to feel more secure.
Mar 31, 2015 Discovery of two new species of primitive fishes
Working with an international team, palaeontologists at the University of Zurich have discovered two new species of Saurichthys. The ~242 million year old predatory fishes were found in the fossil Lagerstätte Monte San Giorgio, in Ticino. They are distinct from previously known Saurichthys species in the shape of the head and body, suggesting different habitats and diet.
Mar 19, 2015 Leadership: Ten Tips for Choosing an Academic Chair
Clear and realistic expectations are key to successfully hiring heads of departments, say Professor Pierre-Alain Clavien, University of Zurich, and Joseph Deiss, former President of the Swiss Confederation, in a commentary in Nature magazine.
Mar 19, 2015 Spinal cord neurons that control pain and itch
The spinal cord transmits pain signals to the brain, where they are consciously perceived. But not all the impulses arrive at their destination: Certain neurons act as checkpoints and determine whether a pain signal is relayed or not. Researchers from the University of Zurich and ETH Zurich identified these neurons and their connections. Moreover, they developed means to specifically activate these neurons, which reduces not only pain – but astonishingly also alleviates itch.
Feb 25, 2015 Playful adults preferred in choice of partner
Which characteristics do young adults value in a potential partner for long-term relationships? A new study by researchers at the UZH reveals that, besides friendliness, intelligence and a sense of humor, playfulness is also important – regardless of gender. Playful people also deem humor, a fun tendency, a laid-back attitude and creativity more important in partners than their non-playful counterparts.
Feb 11, 2015 One in five suicides is associated with unemployment
Every year, around 45,000 people take their own lives because they are out of work or someone close to them is affected by unemployment, as a study by the University of Zurich now reveals. It includes data of 63 countries and demonstrates that during the 2008 economic crisis the number of all suicides associated with unemployment was nine times higher than previously believed.
Feb 5, 2015 Chimpanzees learn «food calls»
Chimpanzees living in captivity are capable of learning calls that refer to specific food items. This was shown by an evolutionary biologist from the University of Zurich together with English researchers. They now published a behavioral study suggesting, that great apes are capable of referring to objects and socially learn meaningful calls.
Antibodies are now established as therapeutics and indispensable in the research lab. In con-trast to high-quality therapeutics, commercial antibodies used in research often do not proper-ly function, as an international group of authors around Andreas Plückthun of UZH have warned. They demand that antibodies used in research should be made by recombinant DNA technology — just like therapeutic antibodies.
Researchers Irving L. Weissman and Joan Massagué have won this year’s Charles Rodolphe Brupbacher Prize for Cancer Research: Weissman, from Stanford University, for his work on healthy and sick stem cells; Massagué, from Memorial Sloan Kettering Cancer Center in New York, for his research on metastatic spread. The award, which carries CHF 100,000 each in prize money, is to be presented on January 29 during the international symposium on “Breakthroughs in Cancer Research and Therapy” in Zurich.
Martin Jinek from the Department of Biochemistry at the University of Zurich has won the Friedrich Miescher Prize, which carries CHF 20,000 in prize money. The award is the highest accolade for budding researchers in biochemistry in Switzerland.
Melanoma, the most aggressive of all skin cancer strains, is often fatal for patients due to the pronounced formation of metastases. Until now, a melanoma’s rampant growth was mainly attributed to genetic causes, such as mutations in certain genes. However, researchers from the University of Zurich now reveal that so-called epigenetic factors play a role in the formation of metastases in malignant skin cancer. This opens up new possibilities for future cancer treatments.
Plants use genetic mechanisms to prevent inbreeding by recognizing self and non-self pollen. Researchers from the Institute of Evolutionary Biology and Environmental Studies at the University of Zurich have now found evidence that a group of 18 male proteins recognize 40 female proteins between them – in contrast to one-to-one relationships studied to date. The self-recognition mechanism in petunia shows similarities to the immune defense in vertebrates.
Jan 7, 2015 Two brain regions join forces for absolute pitch
People who have “absolute pitch” can identify notes immediately without relying on a reference tone. Intensive research is being conducted into the neuronal basis of this extraordinary ability at the University of Zurich’s Department of Neuropsychology. The researchers have now detected a close functional link between the auditory cortex in the brain and the frontal lobe in these extraordinary people – a discovery that is not only important in theory, but also in practice.
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.
