Cleanup crew search for radioactive debris.

In what came to be known as the Thule incident, an American bomber crashed in Greenland, spreading radioactive wreckage across 3 square miles of a frozen fjord. Denmark was not happy.

The superheated plasma inside the fusion reactor is twisted by magnetic fields.

Fusion power, if it works, offers vast amounts of clean energy and almost zero carbon emissions. A new experimental fusion reactor has come online, and it uses a curious twisted stellarator design.

Fusion development takes time. It cannot be developed in miniature and then be simply scaled up. But we must work now, to make it possible to meet humanity's need for abundant, clean energy.
‘A-Day’ marked the first of 23 atomic bomb explosions at Bikini.

In the summer of 1946, the U.S. government detonated the first of many atomic bomb tests in the Marshall Islands. Seventy years of radiation exposure later, residents are still fighting for justice.
Hydrogen is built into helium at a temperature of millions of degrees.
Fire has played a vital role in human history, and will continue to. Recent advances in fusion herald the freeing of fire from captivity back into its natural form.
Great Scott! We’re in the future.

Hoverboards, self-fitting jackets, nuclear fusion generators.... Some of Back to the Future's wacky inventions are closer to reality than you might think.

The nuclear deal South Africa signed with Russia is set to be massively expensive and comes with a fair amount of risks.
Lasers, going where no one has gone before.
Ultra-high powered lasers are the best and even cheapest approach to uncovering the secrets of physics, but with uses closer to home too.
The Joint European Torus (seen here with a superimposed image of a plasma) is one of the machines helping to unlock fusion power.
Why don't we have nuclear fusion power yet? Because it involves taming plasmas at temperatures far hotter than the Sun's core. But the good news is that physicists are slowly but surely figuring out how.
Portable fusion by 2015? Still the stuff of science fiction, sadly.

Researchers in the US have overcome a key barrier to making nuclear fusion reactors a reality. In results published in Nature…
Nuclear power and nuclear weapons: what’s the difference?
It is the received wisdom that nuclear weapons and nuclear power are inseparable. Consequently, any country that builds a civilian nuclear power station is able to build an atomic bomb within a couple…
