"The dark skin is a very interesting finding." Is this what ancient Europeans looked like? http://bbc.in/1gi3J70

Genetic tests reveal a hunter-gatherer who lived 7,000 years ago had the unusual combination of dark skin and hair, and blue eyes.

They've surprised scientists, who thought Europe's early inhabitants were fair.

Researchers find new pathway for neuron repair
Previous studies using many models have shown that when nerve cells, or neurons, are injured they repair the damage through regrowth of axons, the component of a neuron that sends information to other cells, explained co-author Melissa Rolls, associate professor of biochemistry and molecular biology at Penn State. “For example, if you break your arm and the bone slices some axons, you may lose feeling or movement in part of your hand. Over time you get this feeling back as the axon regenerates.”

Given neurons’ capacity for axon regeneration, Rolls and her colleagues wondered whether dendrites, also, could regenerate after injury. This question hadn’t been asked in the scientific community, save for a couple of previous limited-scale studies that yielded mixed results.

Using the fruit fly (Drosophila) as a model system, the researchers took what Rolls calls a “radical approach,” cutting off all of the dendrites in neuron cells. “We wanted to really push the cells to the furthest limit,” she said. “By cutting off all the dendrites, the cells would no longer be able to receive information, and we expected they might die. We were amazed to find that the cells don’t die. Instead, they regrow the dendrites completely and much more quickly than they regrow axons. Within a few hours they’ll start regrowing dendrites, and after a couple of days they have almost their entire arbor. It’s very exciting — these cells are extremely robust.”

Moreover, it appears that dendrite regeneration happens independently of axon regeneration. When Rolls and her colleagues blocked the key signaling molecules that are required for axon regeneration in all animals, they found that dendrites were unaffected and continued to regrow.
“This means that, not only do these neurons have an incredible ability to generate, they have two different regeneration pathways: one for axons and one for dendrites,” she said. “Because it has not even been clear that dendrites can regenerate, it’s a complete open question about what might be involved in that process. The next step will be to look for markers for dendrite regrowth — proteins that are required or genes that are turned on in the process — so we can learn more about what’s going on during dendrite repair. We don’t even know in what scenarios dendrite regeneration might happen in people yet because no one has known that it exists.”
