Proper stem cell function requires hydrogen sulfide
2014-04-17
Stem cells in bone marrow need to produce hydrogen sulfide in order to properly multiply and form bone tissue, according to a new study from the Center for Craniofacial Molecular Biology at the Herman Ostrow School of Dentistry of USC.
Professor Songtao Shi, principal investigator on the project, said the presence of hydrogen sulfide produced by the cells governs the flow of calcium ions. The essential ions activate a chain of cellular signals that results in osteogenesis, or the creation of new bone tissue, and keeps the breakdown of old bone tissue at a proper level.
Conversely, ...

How vision makes sure that little fish do not get carried away
2014-04-17
This news release is available in German. Our eyes not only enable us to recognise objects; they also provide us with a continuous stream of information about our own movements. Whether we run, turn around, fall or sit still in a car – the world glides by us and leaves a characteristic motion trace on our retinas. Seemingly without effort, our brain calculates self-motion from this "optic flow". This way, we can maintain a stable position and a steady gaze during our own movements. Together with biologists from the University of Freiburg, scientists from the Max Planck ...
