With their coalition diminished they must adapt fast: learning to hunt as a twosome and defend their kills without the help of Achilles.

What if there was a museum that contained every type of life form in the universe? This experience takes you on a tour through the possible forms alien life might take, from the eerily familiar to the utterly exotic, ranging from the inside of the Earth to the most hostile corners of the universe. New research is upending our idea of life and where it could be hiding: not just on Earth-like planets, where beings could mimic what our planet has produced, but in far flung places like the hearts of dead stars and the rings of gas giant planets. Nowhere in the universe is off limits. Only when we know what else is out there will we truly know ourselves. This thought experiment will give us a glimpse into what could be out there, how we might find it, and just how far nature’s imagination might stretch.

This film uncovers the intriguing mystery of the return of the African rhino. In the 1800s there were more than 500,000 white and black rhinos in Africa. But by the 1990s, ivory poaching had left less than 7,000 animals alive. Remarkably, today their numbers have risen to 11,000. But there is now a new, deadly threat. Charging Back starts at the Pilansberg Game Reserve, where mysterious, unseen assailants were killing rhinos. Poachers could not be blamed, as the horns remained intact. Unexpectedly, the perpetrators prove to be relocated adolescent elephants, orphaned in culls. Lack of family structure has turned them into aggressive delinquents - a problem which conservation authorities now address by importing the steadying influence of older bulls. In astonishing scenes, the attackers are captured red-handed. Without the least provocation, elephants launch vicious assaults on unsuspecting rhinos.
