Escape From Alcatraz:
9-Year-Old Is in the Swim
* A 9-year-old California boy on Monday became the youngest person ever to swim from Alcatraz Island to the San Francisco shoreline.
Johnny Wilson, a fourth-grader, swam the 1.4 miles in rough, cold waters in less than two hours. He had two adults swimming with him, and kayakers followed the group in case they couldn't complete the swim. When Johnny reached the shore, classmates greeted him with screams of "Go, Johnny!"
By completing the swim, Johnny raised more than $30,000 for Hurricane Katrina victims. He said he was tired and cold, but kept telling himself, "I'm almost there. I'm almost there."
A famous prison was built on Alcatraz Island because the strong currents and cold waters discouraged prisoners from trying to escape. The prison was closed in 1963 and is now a national tourist site.
Follow That Shark!
* Fourth-graders aren't the only ones doing marathon swims, it seems.
A great white shark swam across the Indian Ocean -- from South Africa to Australia -- and back again in nine months, according to a report in the journal Science.
You might be saying: So what? Sharks swim. That's what they do. But this is the first time scientists have been able to prove that there are ties between great whites that live off South Africa and those that live off Australia.
Scientists tracked the female shark, named Nicole after Australian actress Nicole Kidman, using a device that communicated with satellites.
Nicole's 99-day round-trip journey is the first known round-trip swim of an ocean by a shark. It's also the fastest recorded back-and-forth swim across an ocean by any marine animal.
