The return of the wolf
Wolves were reintroduced into Yellowstone National Park in 1995. It was the start of one of the most famous and controversial wildlife restoration projects in the United States. Beginning in the late 19th century wolves had been subjected to a mass extermination programme as ranchers feared the wolf was a threat to their livestock. By the mid 20th century, wolves had effectively been wiped out across the country except for a few isolated pockets in the far north. But the loss of this key predator had a profound impact on the ecosystem. Alex Last has been speaking to Doug Smith, Senior Biologist at Yellowstone National Park, and Wolf Project Leader about the return of the wolf.

Finding El Salvador's missing children
At the end of El Salvador's civil war human rights investigators began the search for hundreds of children reportedly kidnapped by the army during anti-guerrilla operations. In early 1994, two years after the end of the conflict, the first six children were located in an orphanage in the capital San Salvador. Among them was Maria Elsy Dubon, who had been seized by soldiers who killed her father in May 1982. Mike Lanchin has been hearing about Maria Elsy's distressing ordeal and about the difficult reunion she later had with her biological family, who believed that she was dead.(Photo: Peasants who lost their children during military operations in the civil war at a rally in March 2006 (YURI CORTEZ/AFP/Getty Images)

The first human Cyborg
In 1998, a transponder or silicon chip was surgically implanted into the forearm of a British scientist. It sent identifying signals to a central computer that tracked his movements and allowed him access to his workplace, by opening doors and switching on lights. Professor Kevin Warwick has been speaking to Farhana Haider about becoming a more enhanced version of himself and as a result the world's first Cyborg: a man-machine hybrid.Photo: Professor Kevin Warwick with chip transponder Credit: Science Photo Library

The daily disposable contact lens
The contact lens was once a precious and expensive piece of eyewear which had to be looked after and carefully cleaned every night. But that all changed in the 1990s. Ron Hamilton was involved in developing lenses and packaging which could be made so cheaply they could be worn just once and then thrown away. He has been speaking to Ashley Byrne.Photo: Ron Hamilton (l) with his business partner Bill Seden (r) and their wives with their original contact lens machine. Courtesy of Ron Hamilton.
