[Q]: (CNN) -- For decades, skyscrapers have served as iconic symbols of national pride or flashy trophies of corporate wealth, reshaping the skyline of the world's major urban centers. Perhaps in the future, the high-rise superstructures could also help revolutionize the way we travel. That, at least, is the fanciful concept behind the Vertical Hyper-Speed Train Hub, a futuristic proposal of two UK-based architects envisaging trains roaring up and down the side of specially-designed skyscrapers nearly as high as the Empire State Building. Towering above the crowded streets of future metropolises, these giant buildings are designed to minimize the large slices of real estate that major railway terminals occupy by flipping them on their side. The goal, designers Christopher Christophi and Lucas Mazarrasa say, is to free up valuable space in the densely-packed cities of tomorrow, which will be significantly challenged by overcrowding and a sharp drop in public space availability. "In 60 years' time, it will be very difficult for governments to find attractive pieces of available land for public use in the heart of megacities," says Christophi, 27. "Governments will be able to take advantage of such spaces in order to re-adapt the cities' structure to society needs," he adds. How it works . The designer's vertical station concept calls for a tall cylindrical skyscraper whose small footprint would allow the transformation of the surrounding area into an urban park. Passengers arriving at the tower would use a lift to make their way up into the platform and from there into their carriage, which could accommodate 10 people sat in two rows opposite each other. But, you might wonder by now, how could commuters stay on their feet whilst the train slides in hyper speeds along the huge tower's faÃ§ade? The main idea is that instead of traveling on normal rails beneath, the carriages would be supported by magnetic tracks running up the skyscraper's exterior. Each carriage proportion is designed as a cubical shape to enable it to function both vertically, when docked, and horizontally, while traveling After the train's departure, the wagons would pivot like a "Ferris wheel," allowing commuters to remain in an upright position and enjoy breathtaking views of the city. Connecting cities . The radical proposal won the designers an Honorable Mention at this year's eVolo Skyscraper competition, which encouraged people from around the world to propose new ideas for vertical structures of the future. The designers say the towers, which would be capped off by a rooftop green plaza, are envisioned as individual pieces of infrastructure that could be replicated in cities around the world. The hope is to connect a new hyper-speed network of underground tunnels and overground routes where superfast trains would cover distances of 300 miles in 30 minutes. This, they claim, would not only save commuting time and simplify the way public transport is being used, but would also help to cut down CO2 emissions by replacing ways of transport powered by fossil fuels. "Our conceptual design is based upon utilizing existing and viable technologies that can currently be seen in hyper speed rail networks, for example in China," says Mazarrasa, 29, adding that is a matter of time before we're able to reach the rail speeds their concept requires. "The Maglev trains currently travel at 360 miles per hour -- this technology by the 2075 will in no doubt move leaps and bounds from what it already is today, making the hyper-speed trains probably the fastest and safest way of transporting goods and people." Of course, there are a number of limitations to the project -- the proposal deals only with stations designed to accommodate city by city travel, not to mention efficiency issues around loading trains in high volume terminals and connecting train routes. Yet, like in most futuristic transport proposals, practical details are best to take a back seat for now to allow us to enjoy the thrilling ride -- that is, unless you're afraid of heights.

[Q]: (CNN) -- After nearly 40 years of recorded increases, the number of immigrants living in the United States remained flat between 2007 and 2008, recent statistics released by the U.S. Census Bureau show. The number of naturalized citizens in the U.S. increased, partly attributed to voter drives for the 2008 election. According to the Census Bureau's American Community Survey, the U.S. foreign-born population represented about 12.5 percent of the population in 2008, down from 12.6 percent in 2007. Taking into account the margin of error, it was possible that the immigrant population remained even. "Between '07 and '08 there really wasn't that much of a change," said Elizabeth Grieco, chief of immigration statistics staff at the Census Bureau. But given the steep upward trend in the foreign-born population since 1970, no change is big news. The American Community Survey collects data from about 3 million addresses each year, and provides one of the most complete pictures of the population, according to the bureau. The survey doesn't give a reason for the leveling off, but experts pointed to the economic downturn and the resulting high unemployment as factors behind the shift. "The recession has had a significant effect on immigrants' decisions on whether to come to the U.S.," said Michelle Mittelstadt, director of communications at the nonpartisan Migration Policy Institute. Would-be unauthorized immigrants and legal temporary workers are mostly the ones who have decided to stay put in their home countries for now, Mittelstadt said. The largest declines in the foreign-born population were in states that were hardest hit by the recession, including California, Florida and Arizona. Mittelstadt noted, however, that those immigrants already in the United States appear to be staying. A recent study by the Pew Hispanic Center concluded that emigration from Mexico, the largest source of immigrants to the United States, slowed at least 40 percent between mid-decade and 2008, based on national population surveys in the United States and Mexico, as well as Border Patrol apprehension figures. The Mexican-born population in the United States dropped by about 300,000 between 2007 and 2008, according to census data. The new Census statistics show that for the first time since the American Community Survey was fully implemented in 2005, the number of noncitizens decreased, Grieco said. There were about 21.6 million noncitizens in 2008, down from 21.9 million in 2007. The label noncitizens includes both legal residents and illegal immigrants. Along with the decline in the noncitizen population, however, there was a notable increase in the number of naturalized citizens, Grieco said. The number of individuals who are naturalized citizens increased to 43 percent of the foreign-born population in 2008 from 42.5 percent in 2007. The Census survey matches reports from the Department of Homeland Security on the rise of naturalization applications. "Naturalizations grew at a record pace between 2006 and 2008, with a total of 2.4 million immigrants becoming new citizens in the United States," according to a DHS statement. A significant fee increase imposed in 2007 for naturalization applications and an awareness of citizenship brought on during voter registration drives for the 2008 election help explain the increase, Mittelstadt said.

[Q]: (CNN) -- Police arrested another teen Thursday, the sixth suspect jailed in connection with the gang rape of a 15-year-old girl on a northern California high school campus. Jose Carlos Montano, 18, was arrested on charges of felony rape, rape in concert with force, and penetration with a foreign object, said Richmond Police Lt. Mark Gagan. Montano was arrested Thursday evening in San Pablo, California, a small town about two miles from the city of Richmond, where the crime took place. Montano, who was held in lieu of $1.3 million bail, is accused of taking part in what police said was a 2½-hour assault on the Richmond High School campus. Police said as many as 10 people were involved in the rape in a dimly lit back alley at the school, while another 10 people watched without calling 911. The victim was taken to the hospital in critical condition, but was released Wednesday. Four other teenage suspects were arraigned Thursday on charges connected to the rape. Cody Ray Smith, described by the court as older than 14, pleaded not guilty to charges of rape with a foreign object and rape by force. Two other juveniles, Ari Abdallah Morales and Marcelles James Peter, appeared with Smith at the Contra Costa County Superior Court, but did not enter a plea. The court described Morales as younger than 16, and did not give an age for Peter. All three juveniles, who wore bulletproof vests at the hearing, were charged as adults. A fourth person, Manuel Ortega, 19, appeared separately without an attorney and did not enter a plea. He did not wear a protective vest. Another person, Salvador Rodriguez, 21, was arrested Tuesday night, but he was not in court Thursday.
