Question: (CNN)If Usain Bolt ever takes up figure skating, he will know how Kauto Star feels. The 14-year-old racehorse, one of the greatest steeplechasers of all time and a two-time Cheltenham Gold Cup winner, made his dressage debut at London's Olympia Horse Show on Tuesday. Dressage, which involves horse and rider working together to produce a complex "dance" routine marked by judges, is how Kauto Star has been spending retirement since his last National Hunt race in 2012. Laura Collett, a leading British event rider, has been helping the horse to learn the intricacies of a sport that rewards precision and poise above power and pace. "He's changed shape a lot since we got him," Collett told Horse and Hound magazine in the build-up to Kauto Star's demonstration dressage test at Olympia. "He hadn't done any flat work at all. But he's got a brilliant temperament and he's very willing. He got the hang of it very easily. "He needed to soften his whole body -- he was just used to going in a straight line. So he's done a lot of gymnastic exercises and things to supple him up. "He tries really hard. When you've taught him something once, he remembers it. The hardest thing for him was the canter -- he only really knew about going fast." Having spent a career streaking past thousands of spectators lining a racecourse, Kauto Star appeared a little unprepared for an indoor arena crowd as he took his first, dainty dressage steps at Olympia. "It's the crowds being up high and so close, it's quite intimidating," Collett told the BBC afterwards. "He didn't show himself off to the best of his ability -- he got a bit of stage fright and shut down. "Most horses who come into an arena like this have been doing it for eight or 10 years, and build up gradually. He's been thrown in at the deep end." Kauto Star is not in contention for Rio 2016. Britain has one of the world's leading dressage teams and no matter his racing pedigree, there simply isn't the time to bring him up to the required standard. Instead, dressage is seen as a way to offer the horse an interesting retirement -- although that wasn't met with universal approval when the decision was made, two years ago. Owner Clive Smith sent Kauto Star to Collett's Wiltshire yard in December 2012, against the wishes of the horse's longtime trainer, Paul Nicholls. The dispute over the horse's future brought to an end a partnership responsible for almost a dozen major victories on the racecourse, a career bettered only by 1960s legends Arkle and Flyingbolt. Now, by contrast, Collett says there is "no pressure" on Kauto Star to perform to any standard in his new sport. "The main thing is the horse is happy and relaxed," she said this week, "and he has a varied lifestyle."

Question: (CNN) -- All five remaining inmates held in the Mississippi pardons controversy have now been released from prison. Mississippi's Supreme Court last week upheld the controversial pardons of more than 200 convicts that former Gov. Haley Barbour granted on his way out of office, rejecting a challenge by the state's attorney general. In a 77-page, 6-3 ruling Thursday afternoon, the court found the pardons "may not be set aside or voided by the judicial branch." Attorney General Jim Hood argued that no proper notice had been posted in newspapers, but the court found the final decision rested "solely with the governor." "We are mindful that the victims and their families are entitled to be interested in the subject matter of this case, and they are undoubtedly -- and understandably -- concerned with its outcome," Justice Jess Dickinson wrote for the majority. But in the cases before them, it was up to the governor to " decide whether the Constitution's publication requirement was met." In a statement after the court ruling, Barbour said it "reaffirmed more than a century of settled law in our state," but acknowledged that his decision has been difficult for many of the inmates' victims. But in a dissenting opinion, Justice Michael Randolph called the decision "a stunning victory for some lawless convicted felons, and an immeasurable loss for the law-abiding citizens of our state." Hood argued that the state Constitution required that for a pardon to be valid, notices be filed, each day, for 30 days in newspapers where their crimes were committed. But during a February Supreme Court hearing, Barbour's lawyers argued that previous state court rulings had found the 30-day notice rule was "an unconstitutional encroachment" on the governor's power. Thursday's ruling is the final word on the case, but Hood said he would seek to get the notice requirement restored to the state charter. "We do respect the decision of the Court, but feel deeply for how it must weigh on the victims and their families. It is these victims and family members who have lost today and the criminals who have won," he said in a statement, echoing Randolph's dissent. Among the 214 inmates Barbour pardoned before he left office in January were four convicted murderers who had worked as "trusties" at the governor's mansion. Critics argued that the governor failed to consider the families of their victims before freeing them. All four and an armed robber also pardoned by Barbour had remained free while the issue worked its way through the courts, and were freed under Thursday's decision. Five other inmates who had remained behind bars awaiting a ruling have been released. Barbour has defended his pardons and said the former inmates had been rehabilitated. CNN's Martin Savidge and Joe Sutton contributed to this report.

Mississippi's Supreme Court upholds the controversial pardons .
Governor says it was a difficult decision .
He acknowledges his decision has been difficult for inmates' victims .


Question: (CNN) -- Researchers believe the number of children who have an autism spectrum disorder (ASD) is much higher than previously believed, according to a new study published Monday in the American Journal of Psychiatry. By looking at a total population sample in South Korea, the study authors estimate that 1 in 38 children in the country -- or 2.64% -- has some form of autism. The approach is a new one. Previously, researchers have examined only children known to have the neurological disorder or at high risk of developing it. The study authors predicted that if similar studies were conducted in other countries, the prevalance estimates would also go up. The research also led the study authors to believe that more girls than previously thought fall under the autism umbrella. What is autism? In the United States, the most recent estimates from the Centers for Disease Control and Prevention (CDC) for autism prevalence are about 1% or 1 in 110 children, based on population studies in a select number of areas around the country. In this new study, researchers looked at all 55,000 school children in a large metropolitan community of Seoul, which they say is representative not only of South Korea, but also many other developed nations. According to the study, researchers began with 55,266 7- to 12-year-old students. Parents and teachers were asked to fill out an autism screening questionnaire. Parents of 23,234 of the children in the regular school system responded. All 294 children already enrolled in special education or on the disability registry were considered to have tested positive for an autism spectrum disorder. From the initial assessments, 1,214 students screened positive for some form of autism. Only 286 went on to get a full clinical evaluation, of which 201 were diagnosed with some form of autism. Using mathematical algorithms, researchers estimate 1 in 38 children in South Korea have an autism spectrum disorder. "Are we surprised? Yes," said Dr. Young Shin Kim, lead author of the study and assistant professor at the Child Study Center at the Yale School of Medicine. Kim said the prevalence estimates in the study, which happened to take place in South Korea, are higher than previous estimates elsewhere, including but not exclusively the United States. Kim said she believes if more studies like this are done in other countries, they, too, will find an autism rate of 2-3%, while acknowledging that more research needs to be done to validate the study results. In depth autism coverage on The Chart . The study doesn't mean that suddenly many more children have autism, Kim said. Instead, she suggests "they have been there all along but they were not counted in previous prevalence studies," and that "two-thirds are in the community unrecognized and untreated." Roy Richard Grinker, a cultural anthropologist at George Washington University and one of the co-authors of the study, said he thinks the study's estimates are "surprising" but he doesn't think they are alarming. What these estimates tell us, he said, is that "autism is more common than we think it is." Autism and communication . Grinker said he would compare the situation in South Korea to where the United States was 20 years ago, as far as autism awareness goes. He said when the study began in 2005, South Koreans believed that autism was rare in their country. He cited one South Korean official who he said estimated the prevalence of autism to be about 1 in 100,000. At that same time, the CDC estimated autism prevalence to be about 1 in 150 children and Australian researchers believed it to be around 1 in 160 children. Since then, new research has led to a 1 in 110 prevalence estimate. When asked about the newest estimates, Dr. Marshalyn Yeargin-Allsopp, chief of the Developmental Disabilities Branch of the National Center on Birth Defects and Developmental Disabilities at the CDC, said, "We've always said that what we report is an underestimate." She said there are different ways to determine prevalence and that the CDC is considering a total population study of autism, but that it is not yet under way. Vanderbilt University's director of the Treatment and Research Institute for Autism Spectrum Disorders (TRIAD), believes the new data adds to what's already been known about ASD in other parts of the world -- that autism is not rare. But Dr. Zachary Warren, who did not participate in the study, also said, "In the current study the authors sampled from a population, noted that many folks from this sample did not participate, and performed diagnostic evaluations on a relatively small number of children. As such, these concerns suggest interpreting the 2-3% prevalence rate reported with significant caution as it may in fact be an overestimate related to how they studied this specific community in Korea." Dr. Max Wiznitzer, a pediatric neurologist at Rainbow Babies & Children's Hospital in Cleveland, Ohio, said the results of this study (which he also wasn't part of), suggest that what the numbers tell us is "that (many) children in this district in Korea have difficulties with social/communications skills." "We have to be careful not to confuse them with other conditions that can also cause problems in these realms like ADHD and social anxiety disorders," he said. What makes Monday's study different from other autism studies is that researchers sought out children in regular schools. According to the researchers, few children in South Korea are put in special education classes. Grinker said about 10-12% of school children from K-12 classes receive some form of special needs education, but that in Korea that figure is far lower, maybe under 1%. He attributes that to a law that mandates inclusion, which makes it difficult to provide special education. Also, children in regular schools in Korea are in school for up to 12 hours a day, with highly structured, large classrooms, and few opportunities for socialization. Many of the children who were identified with an autism spectrum disorder through this study were found to have a higher IQ, but had poor socialization skills, one of the hallmarks of autism. "I think many children with autism can do well in that highly structured situation and may not get flagged as having a particular problem," Grinker said. This may explain why many children with autism in South Korea may go unnoticed and may explain a significant difference with children in the United States. Dr. Geraldine Dawson, chief science officer of the advocacy group Autism Speaks, which funded part of the study, believes the most important finding is that the research shows that using "the comprehensive sampling approach ... has the potential to yield an autism prevalence estimate that exceeds previous estimates." Grinker believes the most important message from the study is not the numbers, but that it suggests that "autism is more common than we previously thought and that, if we look hard enough, cases will be found and these children need treatment so they can thrive." Dawson also believes that the study clearly confirms that autism is a significant global public health concern that transcends cultural, geographic and ethnic boundaries. It also shows that it's possible to translate and adopt screening and diagnostic approaches developed in English-speaking countries to effectively assess prevalence in other countries. Autism Speaks is funding similar research in India, South Africa, Mexico and Taiwan, Dawson said.
