"### Sweet tooth\\n\\nSome of us really can't have just one sugary treat: A gene that tells our brain when we've had enough is less sensitive to glucose in certain people, so they may overindulge, a study from the University of Toronto reveals. People with this gene variation are more likely to have a higher body-mass index than those without it, but they aren't doomed to be overweight. \\\"Factors you can control, like the snacks you buy, have a bigger impact on eating habits,\\\" says study author Ahmed El-Sohemy, Ph.D.\\n\\n### Party lines\\n\\n\\\"No one is born a Democrat or a Republican, but attitudes that shape your political beliefs are inheritable,\\\" says John Hibbing, Ph.D., Regents professor of political science at the University of Nebraska at Lincoln. His study found that identical twins, who have the same genes, were more likely to agree on issues such as abortion and school prayer than fraternal twins, who share half their DNA. Genes may influence up to 50 percent of our political views, Hibbing says. \\\"Remember that others may see the world differently than you do\u2014you might learn something.\\\"\\n\\n### Cheating hearts\\n\\nGuys carrying a variation of a gene that regulates a hormone receptor linked to attachment are more likely to have a marital crisis, shows a study from the Karolinska Institute in Stockholm, Sweden. But if your guy acts distant, don't seek a gene test. \\\"The gene's impact is too small to be the sole cause of relationship dysfunction,\\\" lead researcher Hasse Walum says.\\n\\n### Shy child\\n\\nInfants born with two short versions of the gene 5-HTT may be more shy when they're feeling stressed, experts at the University of Maryland in College Park note. As these children age, unfamiliar situations feel unpredictable and result in shyness. \\\"This behavior can follow you into adulthood, but it can be overcome,\\\" says study author Nathan A. Fox, Ph.D. Put yourself out there and confidence will build."^^<http://www.w3.org/2001/XMLSchema#string>
