Cascade of Colour

<i>13 April 2014</i><p>The development of <b>melanocytes</b> – the cells that give colour to our skin – is a complicated process. Their growth is controlled by a network of many different genes that can switch on and off at different times, as well as triggering others within the network in a cascade of gene activity. By discovering and mapping out the relationships between these genes, scientists hope to reveal how faults in the system can lead to diseases such as melanoma, an aggressive form of skin cancer. …

How nerve cells flexibly adapt to acoustic signals

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have shown that in order to process acoustic information with high temporal fidelity, nerve cells may flexibly adapt their mode of operation according to the situation. At low input frequencies, they generate most outgoing action potentials close to the cell body. Following inhibitory or high frequency excitatory signals, the cells produce many action potentials more distantly. This way, they are highly sensitive to the different …

The next frontier in 3-D printing: Human organs

The emerging process of 3-D printing, which uses computer-created digital models to create real-world objects, has produced everything from toys to jewelry to food.<p>Soon, however, 3-D printers may be spitting out something far more complex, and controversial: human organs.<p>For years now, medical …

Nonsurgical Fix Could Replace Open-Heart Surgery, Study Suggests

WASHINGTON — A new study gives a big boost to fixing a bad aortic valve, the heart's main gate, without open-heart surgery.
