BIKINI ATOLL
Marshall Islands
The Bikini Atoll is a ring of coral islets encircling a turquoise lagoon that sits in the Pacific Ocean about 2,900km north-east of Papua New Guinea. It was used by the United States as a testing ground for nuclear weapons during the 1940s and 1950s – most notably for the Castle Bravo test in 1954, during which a thermonuclear device was detonated to produce an explosion more than 7,000 times the force of that dropped on Hiroshima.
The blast gouged a crater more than 1.5km across and 80m deep, vaporised two islets and flash-boiled the water in the lagoon, which soared to temperatures of 55,000ºC. It was left a blighted underwater wasteland, devoid of life.
But in 2008, an international team of researchers found a thriving ecosystem had formed up in the crater in the intervening years. While above ground the atoll remains eerily abandoned, its coconuts too contaminated to eat, its waters are now a whirl of kaleidoscopic life, hosting one of the most impressive coral reefs on the planet.
Visiting Bikini in 2017, Stephen Palumbo from Stanford University, California, reported hundreds of schools of fish, from snappers to reef sharks, and described the scene as “visually and emotionally stunning”. Conversely, the fish had been protected from disturbance by the atoll’s traumatic past.

Does cloning create identical copies?
EMBRYOS ARE MADE OF STEM CELLS that divide to give rise to different types of cells, everything from skin to brain cells. Scientists once thought that reproductive cloning creating a genetically identical copy of an individual organism - would be impossible without using stem cells and that the path leading to mature 'differentiated' cells was irreversible. But clawed frogs proved them wrong...
