SEA TURTLES
Sea turtles are known for the amazing migrations they make, swimming long ocean distances to return to their birthplace to hatch their young.
Yet it turns out these beloved marine reptiles make another migration earlier in life that one researcher has described as “even more amazing” than the migrations the turtles make as adults.
“They only do it one time, but [the migration] can be much longer than the reproductive migrations they do as adults, and may involve tens of thousands of kilometers,” said Peter Meylan, a professor of natural sciences at Eckerd College in St. Petersburg, Fla., in a statement.
Meylan, along with his research partner and wife Ann Meylan, of the Florida Fish and Wildlife Research Institute, recently summarized years of sea turtle tracking data in a paper published in the Bulletin of the American Museum of Natural History.
They found that young sea turtles travel extremely long distances before they’re fully grown.
Green turtles hatched in Costa Rica were tracked to far-flung spots — Barbados, North Carolina and Bermuda — before heading off to spend their adulthoods near Nicaragua.
“Bermuda is a place where young turtles go to grow up,” Meylan said. “They arrive there after living out in the ocean. In Bermuda waters they grow from about the size of a dinner plate to the size of a wash tub, and then move on to different, adult habitats,” he said.
The researchers concluded that the tagging data from the study suggest that these adolescent migrations can be a dangerous time for the young turtles, and that the ocean corridors they travel could need official protections.
Some ocean turtle species, such as the world’s largest turtle, the colossal leatherback, are critically endangered.

Carlos Slim, the telecommunications tycoon who controls Mexico’s America Movil SAB (AMXL), is the richest person on Earth, according to the Bloomberg Billionaires Index, a daily ranking of the world’s 20 wealthiest individuals.
The 72-year-old’s net worth fell $478.4 million in a day to $68.5 billion as of the close of markets on March 2, as U.S. moguls Bill Gates and Warren Buffett placed second and third on the list compiled by Bloomberg News. Brazil’s Eike Batista, who ranks 10th, still covets the top spot after vowing a year ago that he’d become the world’s wealthiest man by 2015.

Plan on visiting the Statue of Liberty and Ellis Island via ferry next year? If so, pay close attention to the vessel you board, as it just might be the world’s first to rely on hydrogen, solar and wind power for motorization. Currently, the New York Hornblower Hybrid (not to be confused with the San Francisco Hornblower Hybrid) is under construction in Bridgeport, Connecticut, and if all goes well, it’ll reach completion in April. The 600-passenger boat be equipped with Tier 2 diesel engines, hydrogen fuel cells, solar panels and wind turbines, with power coming from a proton exchange membrane fuel cell that turns hydrogen into electricity. We’re told that the diesel rigs will only kick in to cover “additional energy needs,” but it’s hard to say how often they’ll actually be used. The eventual goal, however, is to do away with emissions altogether in the ferry process, and it seems that the technology is already capable of being scaled for use in other hybrid ferries, hybrid yachts and even hybrid tugs.
