Question: Atlanta (CNN) -- It was somewhere in the middle of Six Flags' Goliath roller coaster that my eye started to short-circuit, nearly going black. The towering roller coaster pressed my fellow riders and me deep into our seats as we rounded a set of sharp curves. Many find the ride thrilling; for me it was unnerving. I spent much of my time in line for the next ride of the day, the Batman roller coaster, reading about the potential for roller coaster deaths and accidents. This was Friday in Georgia, the same day a woman died after falling from her seat on a Six Flags coaster in Texas. Pecking through roller coaster news on my phone that day, before the death in Texas had been reported, I learned, among other things, that it was reported that a 45-year-old died after passing out and having an apparent heart attack on Goliath, the ride that made my eye briefly malfunction. I get that this seems paranoid, and I knew reading this information while waiting in line for a roller coaster was an unnecessary form of self-torture. But I couldn't help it. There's something about a roller coaster death that is uniquely terrifying in a screenplay kind of way. It's summer fun gone horribly wrong. I think this is partly why so many are shocked and saddened by the death of Rosy Esparza, who fell, according to a witness who spoke with CNN affiliate WFAA, from the Texas Giant roller coaster at Six Flags in Arlington, Texas. The exact cause remains unknown, but authorities say there was no sign of "foul play or criminality." Six Flags said in a statement that safety is paramount. "Since the safety of our guests and employees is our number one priority, the ride has been closed pending further investigation," the park said. A park spokeswoman did not immediately respond to requests for comment on its safety inspection policies and the calls for federal oversight. Still, it's a reluctant thrill seeker's greatest fear. It's almost impossible to imagine how terrifying the experience would be -- and how family members and fellow riders could process such an accident. After Esparza's death, Sen. Ed Markey, the Democrat from Massachusetts who recently took the seat vacated by John Kerry, has reportedly renewed his call for federal oversight of roller coaster inspection. "No federal agency has legal authority to enforce safety standards," NBC wrote in a post about the safety issues. "And Texas is one of at least 17 states that have no agency responsible for inspecting amusement park rides, according to NBC News' survey of state codes in all 50 states." Markey wants a federal agency to oversee safety enforcement. The Consumer Product Safety Commission regulates mobile amusement park rides, like those found at fairs, but does not have jurisdiction over "fixed" rides like those at Six Flags, said Scott Wolfson, a spokesman for the federal agency. The difference makes little sense, and Markey isn't alone in his call for more oversight. Tracy Mehan, from the Center for Injury Research and Policy at Nationwide Children's Hospital in Columbus, Ohio, said that relatively little is known about the prevalence of roller coaster injuries and deaths because the federal government doesn't enforce safety inspections and investigations. A patchwork of state laws govern the process, she said. Would-be roller coaster regulators have been criticized as needlessly scaring people about the dangers of roller coasters. And it's true that the statistics aren't quite as terrifying as the rides. As the National Review put it this year, "Americans are 5,000 times more likely to be legally executed by their own government than to die on a roller coaster." The writer, Charles C.W. Cooke, puts the odds of roller coaster death at 1 in 1.5 billion in a given year, compared with a 1 in 10 million chance of being killed "because the aircraft he is traveling on falls apart." But that framing is misleading, given how little is known about national roller coaster injuries. One of the best sources of information comes from a Center for Injury and Policy Research study of child injuries in the United States. After looking at injuries that were treated in hospitals from 1990 to 2010, the group found that a child is hospitalized from an injury related to an amusement park, carnival, fair or arcade-type ride once every three days in the summer, Mehan said. These are serious injuries: fractures, neck injuries and traumatic brain injuries. Including less serious injuries like bruises and sprains, about 4,440 child injuries are reported to hospitals each year on the rides, including those at fairs and other attractions, she said. The rate is 20 injuries per day during the summer months. "We would really like to see a national database or a national system put in place so we can get a picture of what's happening," she said. The group was unable to compile info on deaths, for example. Regardless of the stats, however, it's the joy-gone-wrong factor that makes roller coaster deaths particularly horrifying. Are those fears slightly irrational and disproportionate? Maybe. But safety seems far from assured these days. Improvements, of course, must be weighed against deadlier public safety concerns. More should be done, for instance, to prevent road-traffic deaths, which kill about 1.3 million people globally each year. Many of those deaths could be prevented with simple changes to traffic laws and other rules, according to a fascinating report from Bloomberg Philanthropies (PDF); and self-driving cars could lead to greater reductions, still. But the existence of more-pressing and deadlier threats does not justify lax oversight of amusement park rides that are meant to entertain. Roller coaster fans should support a review of safety requirements. Otherwise, at the very least, they risk having a joyous experience soured by fear.

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.

Question: (CNN) -- While Real Madrid signed Gareth Bale in the summer's highest-profile football transfer and added several other big names, Manchester United fans were left largely underwhelmed by the Premier League champion's moves in the off-season. They might be even more disappointed after learning how much United made in its last fiscal year -- and therefore had to spend. The record 20-time league winner in England -- self described as "one of the most popular and successful sports teams in the world" -- announced record revenues of $580 million for the year ended June 30, 2013 and said commercial revenues soared to a record $244 million. It left executive vice-chairman Ed Woodward, who replaced David Gill in the United hierarchy, to declare on United's website: "It has been a little over a year since our IPO (initial public offering) and in that time we have delivered on our targets and objectives. "Our commercial business continues to be a very powerful engine of growth enabling the team to continue to be successful." But United, in its first season without legendary manager Alex Ferguson, was largely quiet under new boss David Moyes and Woodward as it defends its Premier League title, signing just Marouane Fellaini and relatively unknown Uruguayan Guillermo Varela. United was linked with Cristiano Ronaldo, Cesc Fabregas, Ander Herrera and Leighton Baines -- who all stayed put with their current clubs. "It's been pretty disappointing," said Andy Green, a United supporter who tweets about football finances. "I don't think it's Moyes' fault. He gives his targets to the club. I don't think he should be held accountable at all." Meanwhile, city rival Manchester City bought four key players prior to August, Chelsea swooped for the likes of Samuel Eto'o and Willian and Arsenal smashed its transfer record by purchasing Mesut Ozil from Real Madrid for more than $65 million. Tottenham splashed out on more than half-a-dozen stars, attempting to make up for the loss of Bale. "United's commercial acumen isn't of value because it doesn't lead to a bigger stadium, lower ticket prices or better players," said Green. "You have all these commercial deals but it's no benefit to the football club." United has made a lukewarm start to the league season, winning two of its four games, although it began its Champions League campaign with a win Tuesday against Bayer Leverkusen. United is "delighted to have David Moyes lead our football team into a new and exciting chapter," Woodward said. "We look forward to a successful 2013/14, both on and off the pitch."
