Summary:
Chemist Daniel Norcera recently created a short film titled 'The Artificial Leaf' which explains a new way of creating clean electricity. The process uses a microchip, that when submerged in water and exposed to sunlight, can mimic photosynthesis. Patrick Jones (@Patrick_E_Jones) reports.

Ecuador: The Galapagos Island Under Threat From Climate Change

Deutsche Welle (Oct. 7, 2013) — Ecuador's Galapagos Islands are a Unesco World Heritage site and home to flora and fauna found nowhere else in the world. But one in five native plants as well as nearly 50 percent of its endemic wildlife are under threat from climate change. Rising ocean temperatures are making it harder for species such as the famous Galapagos penguin and the giant tortoise to survive. Scientists with the Charles Darwin Foundation are doing what they can to protect these species from the effects of climate change. A number of changes to the energy sector - such as the introduction of clean electricity - are helping. The island of Floreana has already switched completely to electricity produced by jatropha seeds, which grow in the Manabi region in mainland Ecuador. Jatropha production is also bringing an economic upswing to farmers.

Giant Pandas

Giant Pandas

National Geographic (Mar. 18, 2012) — Habitat loss and slow natural reproduction have landed pandas on the endangered list. At China’s Wolong Nature Reserve, scientists oversee an innovative captive breeding program that uses artificial insemination to attempt to increase panda populations faster. However, a major earthquake in 2008 destroyed the panda’s habitat and cut off their food, threatening the breeding season. Wild Chronicles reports from China on the state of the panda.

Australia: From Tuna Hunter to Sushi Saver

Deutsche Welle (Apr. 30, 2012) — Bluefin tuna are threatened by extinction as the global appetite for the fish soars. A fishing ban is unlikely, so one solution is to breed the fish in underwater cages. But they're not easy to rear in captivity. In Australia, German-born Hagen Stehr is working to mimic natural living conditions of the fish in his onshore farm. The idea is to create an artificial model of the journey to their spawning grounds in order to trick the fish into reproducing.
