Whether a tumour develops from individual cancer cells and whether metastases are formed depends on many factors in the affected tissue. A greater understanding of a tumour’s complex switch and control circuits could help to combat cancer in a more targeted fashion. Researchers at the University of Zurich have come up with an imaging method that is able to simultaneously visualize a previously unachieved number of factors involved in cancer.
After a stroke, sufferers are often faced with the problem of severe movement impairment. Researchers at the Brain Research Institute of the University of Zurich have now discovered that the brainstem could play a major role in the recovery of motor functions. The projection of neurons from this ancient part of the brain into the spinal cord leads to the neural impulses needed for motion being rerouted.
Feb 5, 2014 Attractive professional cyclists are faster
A study by the University of Zurich demonstrates a link between attractiveness and endurance performance, showing that successful Tour de France cyclists are more attractive. This preference for faster riders is particularly strong in women who are not using a hormonal contraceptive.
Researchers at the University Children’s Hospital Zurich and the University of Zurich have engineered skin cells for the very first time containing blood and lymphatic capillaries. They succeeded in isolating all the necessary types of skin cells from human skin tissue and engineering a skin graft that is similar to full-thickness skin.
Jan 29, 2014 Zebrafish use sunscreen also for camouflage
Zebrafish embryos camouflage themselves against predators by adapting to the surface. Neurobiologists from the University of Zurich have discovered that this camouflage mechanism actually started out as sunscreen to protect the fish against DNA damaging shortwave solar radiation at embryonic stages.
Back in the Middle Ages, Central Europeans were already capable of digesting milk, yoghurt and cheese just as well as us today. Researchers at the University of Zurich’s Centre for Evolutionary Medicine have discovered that the population of the medieval town of Dalheim had a similar genetic predisposition for milk digestion to present-day Germans and Austrians. Moreover, the study reveals that lactose tolerance was more widespread than previously believed.
Jan 20, 2014 Cocaine users enjoy social interactions less
Regular cocaine users have difficulties in feeling empathy for others and they exhibit less prosocial behavior. A study at the Psychiatric Hospital of the University of Zurich now suggests that cocaine users have social deficits because social contacts are less rewarding for them. Social skills should therefore be trained during the treatment of cocaine addiction.
