A ranch in Fairbanks, Alaska, offers yoga classes with reindeer. An owner says the animals are particularly well-suited to it because they are twisty creatures.
Reindeer are thought to face a grim future as climate change threatens lichen, a key winter food source. But on one Alaskan island, reindeer have found a new food source, making scientists hopeful.
Zombie bacteria in defrosting reindeer carcasses brought anthrax back to Siberia. Now the government wants to slaughter 250,000 reindeer to stop the spread.
The reindeer died on a mountain plateau in central Norway. "I don't remember hearing about lightning killing animals on this scale before," says a Norwegian environmental official.
Russia is experiencing its first anthrax outbreak in more than 70 years. One child died. Health officials think it might have been triggered by warming permafrost, which unleashed dormant bacteria.
Tinsel, a rare albino reindeer who is the main attraction at a Christmas tree farm in England, has hoofed it. After escaping his enclosure, he remains on the loose.
