This week, we hitchhike from Tasmania to London, get a good night's sleep, protect a 300,000 miles of ocean, hike 2,600 miles in winter, and stop forests from burning down.

This week two adventurers shed tears at the South Pole and paddle from Australia to New Zealand; then we learn about eradicating malaria, which is responsible for "one half of human deaths since the Stone Age"; pick the perfect beer for all occasions; and learn about the secrets of America by night.

This week, we have a close encounter with a moose with a team of dogs; eat moths with bears and salmon brains with wolves; visit China's secret tiger farms; learn the science behind the sunrise; examine the promise of "clean coal".

This week, we find out what is the tallest mountain in Alaska's Brooks Range; swab New York City's subway system to see what bacteria we find; photograph Egypt's revolution and try not to get hurt; discover glow in the dark sharks; and learn about the new fungus that's eating our bananas.

This week, we summit North America's tallest mountain alone in January; take photo lessons from one of National Geographic's top photographers; find the world's largest gathering of snakes in an unexpected place; know when to turn around on South Asia's tallest mountain; and celebrate "Carnevale" like an Italian.

This week, we dodge humpbacks and killer whales in a feeding frenzy, climb up a frozen Niagara Falls, explore Mexico's poisonous "snot caves", diagnose the invisible injuries of American war veterans, and visit Iraq and Syria's frigid refugee camps.
