...involve not only the original area, but other organs or tissues as well. It can, however, be combined with other systemic treatments, such as chemotherapy, to treat metastatic disease, and has often been used to treat solid metastatic tumors most commonly found in the lungs, liver, spine and brain. And the technology is continually evolving. The company's Synchrony program allows doctors to irradiate lung tumors by synchronizing the robotic arm with the rise and fall of a patient's breathing. Says Thomson: "Our dream is that we'll make radiosurgery an option for every cancer patient...
...small study, the researchers scanned the brains of 26 men as they each performed a simple task: choosing one symbol from a pair of symbols. After each selection, the participant was presented with a smiley face or sad face, depending on the symbol he had chosen. All men were equally good at learning to pick the symbols that won them a smiley face, but some men were worse than others at avoiding the ones that resulted in sad faces. Those men, it turns out, had a particular gene variant, or allele, that reduces the density of receptors for dopamine...
...perform markedly worse on the task at hand: They selected the good symbols from the bad about as often as participants who didn't have the allele. The results suggest that learning - though influenced by dopamine - is a complex process that involves much more than one kind of brain receptor. "It's just one factor that may contribute to some problems that might arise in some people," says Markus Ullsperger, a co-author of the Science paper, based at the Max Planck Institute for Neurological Research in Cologne. "I think you can compensate for many things without even noticing...
...Mind Your Morals The article's title, "What Makes Us Moral," contains the basic mistake we make in trying to understand ourselves and our fellow human beings [Dec. 3]. Nothing makes us anything. We make choices, which then affect our brain chemistry. In trying to be scientific, we often reverse the relationship. While Jeffrey Kluger may value the choices we make, he did not use the word choices in his examination of morality. The connection we have with our community is a powerful factor in how we choose to behave, of course, and we do place others outside our community...
