Since the early twentieth century, fortune hunters have mounted expeditions deep into the rainforests of Honduras’s remote La Mosquitia region, searching for a fabled city called ‘La Ciudad Blanca’. This ‘White City’ was spoken of by indigenous groups there, from stories passed down from their ancestors, whom used the city as a refuge from invading conquistadors.

A few weeks ago, Unknown Country reported that NASA were investing millions of dollars into a new laser-based instrument, located on the International Space Station,  which is intended to provide a unique 3-D view of Earth’s forests. The focus of its mission is to provide definitive information about the role of forests in the carbon cycle, and as such, in global warming.

The laser, known as the Global Ecosystem Dynamics Investigation (GEDI) lidar, the instrument will be the first to systematically probe the depths of the forests from space, and assess how they affect our weather systems and other ecosystems.

 Following the discovery of a ‘Lost world’ full of unknown species in an unexplored Australian rainforest last week, a team of researchers working for the Wildlife Conservation Society, the American Museum of Natural History, and numerous other groups have found a species of humpback dolphin previously unknown to science swimming in the waters off northern Australia.
