The 6-3 ruling challenges some common political assumptions about conservatives and liberals.
Saudi Arabia has many possible motives for pursuing nuclear power.
Exporting nuclear technology is lucrative, but without strict safeguards, buyers could divert it into bomb programs. Why is Saudi Arabia shopping for nuclear power, and should the US provide it?
The Supreme Court is likely to rule on the case by June.

Distrusting large federal bureaucracies isn't reserved for conservatives anymore.
Curies and curiouser.
With its strange bluish glow and cancer-killing qualities, meet the wundermetal that became one of the great cautionary tales of modern times.

The Trump administration's push for 'energy dominance' could spur a new wave of domestic uranium production. A scholar describes the damage done in past uranium booms and the visible scars that remain.
Radon gas is the leading cause of lung cancer in non-smokers. Children are most at risk of exposure in homes, especially during the winter months.
Radon is a radioactive gas that seeps into buildings through foundation cracks. It is the leading cause of lung cancer in non-smokers. And it only costs around $60 to test your home.
For the first time, human beings harnessed the power of atomic fission.
By figuring out fission, physicists were able to split uranium atoms and release massive amounts of energy. This Manhattan Project work paved the way both for atomic bombs and nuclear power reactors.
Celebrations outside the Western Cape High Court after it ruled against the South African government’s proposed nuclear deal.
The Cape High Court ruling which declared South Africa's nuclear energy plan as illegal may have put paid President Jacob Zuma's ambitions of clinching the deal while he is still in office.

Eight Tanzanians have been arrested in Malawi after looking into a uranium mine. They say the country has no right to flout the rule of law and to harass groups acting in the public interest.
Marcoo was a 1.4 kilotonne ground-level nuclear test carried out at Maralinga in 1956. The contaminated debris was buried at this site in the 1967 clean-up known as Operation Brumby.
History is writ large in the remote areas around Woomera and the Nullarbor: from the fossils of microscopic, cell-like creatures to ancient stone tools to the deitrus of rocket tests and the painful legacy of the Maralinga atomic blasts.

After a Royal Commission and a citizens' jury, South Australian Premier Jay Weatherill has enough advice to decide on his nuclear waste dump plan. Which makes his decision to hold a plebiscite baffling.
Artisanal miners at an illegal mine pit in the DRC. At severe risk to their health, some still go to abandoned sites to dig out uranium and cobalt.
The mine that produced the uranium that made the Hiroshima bomb has since been closed. But its troubling legacy continues to haunt the Democratic Republic of Congo and the local community.
The policy failures behind the upbeat headlines.
The Arak heavy-water reactor has been at the center of concerns about potential Iranian nuclear proliferation.
Critics of the nuclear deal with Iran have good reasons to be skeptical, but blocking the deal would make the United States and its allies less secure.
No one’s a fan of nuclear waste. What if we could just recycle it all?

Even the biggest proponents of nuclear power can't ignore 10,000 metric tons of spent fuel globally every year. What if we could recycle every last atom of nuclear waste?
You need to take a wider view to work out the true greenhouse emissions from nuclear power.

Nuclear power isn't 'zero-emission', as many proponents claim. Factor in uranium mining, power plant construction, and other factors and it has similar emissions to wind power. But that's still lower than fossil fuels.
Talks in Switzerland in late March.
Centrifuges, plutonium, uranium enrichment – what's the nuclear science behind the deal to curb Iran's atomic weapons program.
Thorium has its advantages over uranium nuclear power, but is it right for Australia?
Thorium has several advantages over uranium nuclear power, but it also has its drawbacks. However, the question remains whether it would be the right technology should Australia choose to go nuclear.
