...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." In fact, a huge number of people have the genotype that Ullsperger studied, and never have trouble learning from their mistakes: About...
...progressive: as kids' BMI increased, their risk of adult heart disease rose alongside it. "We anticipated finding a threshold, or a cut point at which the risk dramatically increased or remained stable, so when it worked out to be such a proportional increase we were very surprised," says co-author Dr. Jennifer Baker, of the Center for Health and Society at the Institute of Preventive Medicine in Copenhagen. "The association we found is very straightforward, the higher a child's BMI in childhood from the ages of 7 to 13, the greater the risk of heart disease in adulthood. They...
...most, and to ignore that reality would only invite trouble. Instead, says Bart Jones, author of a new Chávez biography, !Hugo!, it's time for Chávez and chavistas "to stop thinking about the Bolivarian Revolution as a one-man show and start cultivating other leaders." Alberto Barrera, co-author of another biography, Hugo Chávez, agrees: "Chavistas have unfortunately reached that ideological point where they can't even imagine any other President." If so, however, they risk leaving chavismo - and in turn Venezuela's poor - politically orphaned in the 2012 election against a more conservative opposition...
...scientists wrote in the British Medical Journal that absinthe bottled before 1900 packed up to 260 p.p.m. of thujone--which may not sound like much, but consider that only 15 parts per billion of lead in drinking water is enough to scare regulators. "They are playing pretend," study co-author Wilfred Arnold says of the liquor's new cheerleaders. "It is nothing like the old stuff...
...several hundred field workers (asking, for example, whether donors collaborate well with non-profits and businesses). In short, the index reviews how well countries are following their own global donor guidelines. "If you take the top from the bottom, there are big differences," says Silvia Hidalgo, DARA director, and co-author of the report. Sweden is this year's clear winner, first in a stunning 19 of the 57 categories, because it gives funds quickly, in cash, and follows up predictably as long as projects pass their regular parliamentary reviews...
