Less parental warmth and a more harsh work environment affect how aggressive children become and whether they lack empathy and a moral compass, according to a new study.Researchers at the University of Michigan, University of Pennsylvania and Michigan State University studied 227 pairs of identical twins. They analyzed differences in the parenting that each twin experienced to determine whether the differences predicted the emergence of antisocial behaviors.The study found that the twin who experienced harsher treatment and less emotional warmth had a greater chance of showing aggression and a lack of empathy and moral compass.These characteristics are known as callous-unemotional traits."The study convincingly shows that parenting—and not just genes—contributes to the development of risky callous-unemotional traits," said Luke Hyde, U-M associate professor of psychology. "Because identical twins have the same DNA, we can be more sure that the differences in parenting the twins received affects the development of these traits."Parents of the twins completed a 50-item questionnaire about the home environment, establishing their harshness and warmth levels.The work, published in the Journal of the American Academy of Child and Adolescent Psychiatry, is the latest in a series of studies from Penn's Rebecca Waller, assistant professor of psychology, and colleagues using observation to assess a variety of aspects of parenting. "Some of the early work on callous-unemotional traits focused on their biological bases, like genetics and the brain, making the argument that these traits develop regardless of what is happening in a child's environment, that parenting doesn't matter," said Waller, lead author of the current study. "We felt there must be something we could change in the environment that might prevent a susceptible child from going down the pathway to more severe antisocial behavior."Waller says a potential next step to turn these findings into interventions for families trying to prevent a child from developing these traits or to improve troubling behaviors. "From a real-world standpoint, creating interventions that work practically and are actually able to change behaviors in different types of families is complicated," she said. "But these results show that small differences in how parents care for their children matters. Our focus now is on adapting already-successful parenting programs to include specific interventions focused on callous-unemotional traits as well."For more information, click here. 2577

LA JOLLA, Calif. (KGTV) - Scientists at the Scripps Institution of Oceanography say atmospheric rivers will be the main source of California's rainfall over the next 80 years.The study, released Tuesday morning, says that could lead to more flooding, more drought and longer wildfire seasons."This region is becoming more sub-tropical and the dry season is expanding," says Alexander Gershunov, a research meteorologist at Scripps. "That is the case with all of the Mediterranean climate regions around the world."Right now, the study says California gets 40-50% of its annual rainfall from atmospheric rivers. Those are long, drawn out rain events that last for days. San Diego experienced several of them this past winter, leading to record rainfall.RELATED: Atmospheric river triggers evacuations in Southern California"These are warm storms," says Gershunov. "The mountains squeeze the rain out of them.""In California, most of the floods, historically, are associated with atmospheric rivers," says Gershunov. "So stronger atmospheric rivers definitely means more floods."RELATED: Scripps Institute uses Air Force to track atmospheric riversThe study says the dry periods between the storms will also be longer, leading to more dead brush and drought-like conditions. That could raise the likelihood of brush fires extending well into the winter.RELATED: UC San Diego creates ranking system for atmospheric riversThe study looked at atmospheric river data from the last 70 years and also predictive models for the next 80 years. Gershunov says this new information means the state will need to increase the amount and type of tools we use to manager water."This is really talking about decades into the future," he says. "These are the kind of time scales we need to understand to envision what the future of water resource management will look like." 1865

Lee Keum-seom hasn't held her son in 68 years.The last time she saw him, Sang Chol was four years old, and together with her husband and their daughter, they were headed south, fleeing the fighting during the early days of the Korean War.In the mass of hundreds of thousands of others trying to escape, Lee and her daughter lost sight of her husband and Sang Chol.They continued south, becoming part of the flood of refugees who crossed what became the Demilitarized Zone. Only later did she discover that her husband and son remained on the other side of the divide, in North Korea.They are among the tens of thousands of Koreans whose families were separated by the war.Lee is now one of a small number of people fortunate enough to be chosen for government-run family reunions.On Monday, the first reunion in three years will take place, at North Korea's Mount Kumgang. The reunion is included in the historic accord that was signed by the leaders of the two Koreas in April. Around 57,000 people were eligible to take part. Of those, 0.16 percent, just 89 people, will make the journey. 1098
