Several thousand soldiers from the 82nd Airborne Division are taking part in what is being called the last major combat offensive of the Afghan War.

Their task is to clear Ghazni province in eastern Afghanistan, a Taliban stronghold and a key prize because it straddles the major roads to Kabul and the insurgent supply routes into Pakistan.

But the American troops are challenged by a stubborn enemy and a short time to finish the job.

Swimmer Spyros Gianniotis was born in Liverpool, England, but he will represent Greece in the upcoming London Olympics. At 32, he is the 10-kilometer open-water world champion, and one of Greece's best hopes for a medal in London. He's on a team of Olympians whose training budget has been drastically reduced by austerity measures and the economic crisis.

On a recent morning, Gianniotis' training included three hours of laps in an outdoor Olympic-sized pool in central Athens. The lean, freckled marathon swimmer glides to the end of the pool.

A kibbutz in the mountains of northern Israel might seem an unlikely source for some of the world's most expensive gourmet food. But a small farming collective has built itself a lucrative business, supplying some of America's top chefs with caviar that customers pay hundreds of dollars to sample.

When it comes to architecture, sustainability and affordability can mean many things: Salvaged wood becomes new flooring, old newspapers are shredded into insulation.

But a few architects are taking green building one step further: creating entire homes and businesses out of discarded shipping containers — an approach some have dubbed "cargotecture."

Approximately a quarter-million shipping containers pass through Oregon's Port of Portland each year. These are big boxes — 40 feet long and weighing thousands of pounds.
