...first strong physiological evidence that the density of dopamine receptors may affect how people respond to negative inputs. Previous studies have established a strong link between a low density of dopamine receptors and addiction, obesity and compulsive gambling - conditions that suggest an impaired ability to learn from the consequences of bad decisions...
...your mistakes. Although the men who had the genetic variant did show weaker responses to negative feedback, they did not 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...
...spread the virus. The problem is particularly acute in developing countries, where inadequate utilities mean residents must store water in jars and tanks - prime breeding grounds for the Aedes aegypti. Increasing air travel is also a factor as infected fliers spread the disease quickly worldwide. "It's simplistic to suggest that the increasing outbreak is solely caused by climate change," says Simon Hales, a senior research fellow at New Zealand's University of Otago. "But those who would suggest that it has nothing to do with it are equally misguided." Hales estimates that if global warming advances as predicted...
...Bolton said if the U.S. were ever to use military force against Iran, the nation would "need to make it clear to the people of Iran that this is not aimed against them." Does he suggest sending that message before Iranian people are maimed and killed - or after? Neil McKenty, Montreal...
Chávez insisted in a TIME interview last year that "capitalism is the way of the devil." But while Chávez, who controls the hemisphere's largest crude reserves, has used his awesome oil windfalls to reduce poverty, Venezuelans now suggest they want to increase capitalist investment, satanic as it may be, to solve their nagging unemployment. They appreciate his shrewd efforts to raise oil prices, but they'd also like him to lower inflation, Latin America's highest. And while they admire him for enfranchising the majority poor, they'd applaud as loudly if he did something to reduce...
