PROBLEM: (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."

PROBLEM: (CNN) -- Four groups that advocate for immigrant rights said Thursday they will challenge Arizona's new immigration law, which allows police to ask anyone for proof of legal U.S. residency. The Mexican American Legal Defense and Educational Fund, the American Civil Liberties Union, the ACLU of Arizona and the National Immigration Law Center held a news conference Thursday in Phoenix to announce the legal challenge. "The Arizona community can be assured that a vigorous and sophisticated legal challenge will be mounted, in advance of SB1070's implementation, seeking to prevent this unconstitutional and discriminatory law from ever taking effect," said Thomas A. Saenz, president of the Mexican American Legal Defense and Educational Fund, known as MALDEF. "This law will only make the rampant racial profiling of Latinos that is already going on in Arizona much worse," said Alessandra Soler Meetze, executive director of the ACLU of Arizona. "If this law were implemented, citizens would effectively have to carry 'their papers' at all times to avoid arrest. It is a low point in modern America when a state law requires police to demand documents from people on the street." Republican Arizona Gov. Jan Brewer signed the law last week. It goes into effect 90 days after the close of the legislative session, which has not been determined. Brewer and others who support the law say it does not involve racial profiling or any other illegal acts. "Racial profiling is illegal," Brewer said after signing the bill Friday. "It is illegal in America, and it's certainly illegal in Arizona." The National Coalition Of Latino Clergy & Christian Leaders said Sunday it also planned legal action. "Our churches and pastors in Arizona are outraged about the significant threat this anti-immigrant law will have in the lives of Arizona's Latinos," said the Rev. Miguel Rivera, the group's chairman. "This policy violates the rights of American citizens, particularly the fast-growing Latino population of Arizona, by eliminating the basic right of due process, which we are certain that the courts will agree," Rivera said. The law requires immigrants to carry their alien registration documents at all times and requires police to question people if there is reason to suspect they're in the United States illegally. The measure makes it a state crime to live or travel through Arizona illegally. It also targets those who hire illegal immigrant day laborers or knowingly transport them. In addition to signing the law, Brewer also issued an executive order that requires training for local officers on how to implement the law without engaging in racial profiling or discrimination. "This training will include what does and does not constitute reasonable suspicion that a person is not legally present in the United States," she said. Some officials in Arizona have expressed their displeasure with the measure. Phoenix Mayor Phil Gordon said Thursday that he is "very disappointed." He said he is concerned that calls to boycott Arizona businesses and tourism will harm the state. "I'm very incredulous that our state leaders -- our so-called leaders -- have allowed our state to be split when we're suffering economic hardships," Gordon told CNN. Other critics say the bill is unconstitutional and will trample residents' civil rights. "Quite simply, this law is a civil rights disaster and an insult to American values," said Mary Bauer, legal director of the Southern Poverty Law Center. "No one in our country should be required to produce their 'papers' or demand to prove their innocence. What kind of country are we becoming?" But a national Republican leader said Thursday that Arizona is just filling a void left by the federal government. "I think the people of Arizona have a right to pass their laws under the 10th Amendment," House Minority Leader John Boehner said. "I think it is clearly a result of the federal government's failure to secure our border and to enforce our laws." Gordon said the real solution is comprehensive immigration reform that would allow more immigrants to legally enter the United States. "This law doesn't accomplish that," he said. "It doesn't do anything on that." President Obama has called on Congress to pass a comprehensive immigration reform law this year. CNN has learned that Senate Majority Leader Harry Reid and other top Democratic senators will unveil the outlines of that legislation late Thursday. But Boehner said at a briefing Thursday that "there's not a chance" that Congress will approve the measure this year, especially after the recent passage of a health care reform bill. "I've been out here for a little while and know that in the middle of an election year, after we've had bills like health care shoved down our throats and the process twisted, tortured, pressured, bribed, you cannot do a serious piece of legislation of this size, with this difficulty, in this environment," he said. "And it's nothing more than a cynical ploy to try and engage voters, some segment of voters, to show up in this November's elections." The Arizona measure has drawn sharp criticism from the Mexican government, which issued an advisory to its citizens this week. The secretary general of the Organization of American States and some member states also expressed concerns about the law Wednesday. "This is an issue of concern to all citizens of the Americas, beginning with the citizens of the United States, a country with a very rich tradition of immigration and respect for immigrants who have come to lead a better life," OAS Secretary General Jose Miguel Insulza said. "The rich tradition we all admire, of recognizing immigrants in the United States, has been harmed, undermined." The uproar caused by the law has even spread to the nation's pastime. Protesters plan to demonstrate against the Arizona Diamondbacks baseball team Thursday outside Wrigley Field in Chicago, Illinois. In Arizona, two popular singers also will voice their opposition. Grammy Award-winning Colombian singer Shakira is scheduled to meet with Gordon on Thursday evening. Singer-songwriter Linda Ronstadt, an Arizona native of Mexican and German descent, also attended the Thursday afternoon rally with the immigrant rights groups. "What Gov. Brewer signed into law last week is a piece of legislation that threatens the very heart of this great state," Ronstadt said. "We must come together and stop SB1070 from pitting neighbor against neighbor to the detriment of us all." Federal officials estimate there are about 10.8 million illegal immigrants in the United States, of which about 6.6 million come from Mexico and 760,000 from the rest of Latin America. About 1 million come from Asia. Arizona, which is on the Mexican border, has about 460,000 undocumented immigrants, the federal government says. At least five other states, including California, with 2.6 million, have more undocumented immigrants, the government says. The other states with more illegal immigrants than Arizona are Texas, Florida, New York and Georgia. A Pew Research Center survey late last year found that Americans believe Latinos are discriminated against more than any other major racial or ethnic group in American society. The Pew survey also indicated that about one-third of the nation's Latinos say they or someone they know has experienced discrimination. About 9 percent said they had been stopped by police or other authorities and asked about their immigration status in the year before the survey. Fifty-seven percent of those surveyed said they worried that they, a family member or a close friend could be deported.

PROBLEM: (WIRED)  -- Apple's loose-lipped overseas partners are exchanging whispers about the next-generation iPad, claiming it will come in three different versions, one of which would work with Verizon's network. The iPad 2 will support three different wireless configurations: UMTS, CDMA and Wi-Fi only, according to "industry sources quoted by DigiTimes" citing component makers. That's up from the two versions Apple currently offers: UMTS plus Wi-Fi, and Wi-Fi only. To explicate the alphabet soup, UMTS is the standard used by major 3G carriers such as AT&T and T-Mobile, while CDMA is compatible with Verizon and Sprint networks. Currently the 3G iPad ships with a MicroSIM card slot, and in the United States, the only carrier that uses MicroSIM is AT&T. Customers who want to connect to non-AT&T 3G networks must either buy an external wireless hotspot device such as the Verizon MiFi (Verizon already sells a MiFi plus iPad package) or trim a standard SIM card down to MicroSIM size, like Wired.com's Charlie Sorrel. The current 3G model of the iPad is not tied to a contract: Customers pay a flat monthly rate for data and can opt out whenever they please. So if this rumor is true, it means that when the iPad 2 ships, you'll have to pick a 3G model based on your carrier preference. If you don't plan to be on the road a lot, there's still the Wi-Fi option. Support for both major wireless standards in the United States will make the iPad 2 available to a much larger potential audience, whereas before it was only available in the states from AT&T. WIRED: With iPad, Apple still has fatal attraction for AT&T . Whether Apple hammers out sales agreements with Verizon or Sprint remains to be seen. Recent rumors suggestion that the iPad 2 will hit stores April 2011, one year after the original iPad's release. Some third-party protective cases for a purported "iPad 23 have been cropping up in Asia, hinting at the possibility of a bigger speaker and a rear-facing camera. Persistent rumors -- so far unsubstantiated -- have also pointed to a Verizon-compatible iPhone to be released in early 2011. If Verizon gets the iPhone and the iPad, it would greatly expand Apple's potential market, and would also likely deal a severe blow to AT&T, which has been roundly criticized for the inability of its 3G network to keep up with iPhone-induced demand.
