Bringing law to the sea: safeguarding the naval nuclear fuel cycle

Sébastien Philippe

As non-nuclear weapon states like Brazil develop nuclear-powered submarines, it will become necessary to verify that naval nuclear material is not diverted for nuclear weapons use. But how?

Reprocessing: Only where appropriate

Yun Zhou

The author argues that reprocessing spent nuclear fuel may be appropriate for a large developing country such as China, but smaller countries will probably have to be satisfied for the time being with dry storage.

Mexico’s stolen radiation source: It could happen here

Why a consumer society can't fix the climate

A changed relationship with nature

Pablo Solón

The author argues that the international climate regime must set ambitious targets for emissions reductions; that countries with high historical emissions must not be allowed to wriggle out of their commitments; and that nations must seriously question the need for endless economic growth.

What biofuels can do

José R. Moreira

The author argues that increased use of biomass energy poses little threat to food security, and that biofuels in particular can play a very significant role in mitigation of climate change.

The devil’s in the details

The author writes that bioenergy's ability to meet energy needs, mitigate climate change, and avoid adverse effects on food production depends on factors such as the technology and feedstock used and the scale of production.

Why humans should go to Mars

Laura H. Kahn

Humans first emerged from Africa around 60,000 years ago in search of new lands to explore and colonize. Since then, we've spread out across much of the planet and even gone into low Earth orbit in the International Space Station. The need to explore new frontiers appears to be embedded in our DNA.

Minimizing danger, maximizing headaches

Charles Piani

The author writes that managers of research reactors debating whether to convert to low-enriched uranium must decide, among other things, whether conversion is feasible and whether it can be carried out in an efficient, economical way.

An open letter to President Obama: The time on the Doomsday Clock is five minutes to midnight

Robert SocolowThomas RosenbaumLynn EdenRod EwingAlexander GlaserSivan KarthaEdward "Rocky" Kolb Leon LedermanRamamurti RajaramanM. V. RamanaRobert RosnerJennifer SimsRichard C. J. SomervilleElizabeth J. Wilson

Editor's note: Founded in 1945 by University of Chicago scientists who had helped develop the first atomic weapons in the Manhattan Project, the Bulletin of the Atomic Scientists subsequently created the Doomsday Clock in 1947 using the imagery of apocalypse (midnight) and the contemporary idiom of nuclear explosion (countdown to zero), to convey threats to humanity and the planet.

Water, climate, and thorium: Why nuclear power makes sense for South Africa

New START: One year later

Kingston Reif

February 5 marks the one-year anniversary of the New Strategic Arms Reductions Treaty's (New START) entry into force. Signed by the United States and Russia in April 2010, New START caps each country's nuclear arsenal at 1,550 deployed strategic warheads, 700 deployed strategic delivery vehicles (long-range missiles and bombers), and 800 deployed and non-deployed strategic launchers (long-range missile tubes on submarines, missile silos, and bombers).

The banality of death by nuclear power

Kennette Benedict

Scientists estimate that 1,000 people will die from cancer as a result of their exposure to radiation from the Fukushima Daiichi disaster. This number is often contrasted with the 20,000 who died in the March 11 earthquake and tsunami that caused the nuclear debacle -- presumably to suggest that the 1,000 deaths are less significant and should not be used to justify a nuclear power shutdown.

The "scientization" of Yucca Mountain

Dawn Stover

When I first stood atop Nevada's Yucca Mountain more than 16 years ago, the Energy Department was spending about $1 million a day to assess the feasibility of safely storing spent fuel and high-level nuclear waste there. A steel-toothed tunneling machine had already begun chewing its way into the ridge, and some 300 scientists were on-site studying the area's underground trickles, its porous rock, its lumbering desert tortoises, and a few reddish-black cinder cones that dotted the landscape below -- the ominous tombstones of ancient volcanic eruptions.

What alternatives to nuclear energy?

Charles Forsberg

For those opposed to nuclear energy, the belief is that there are alternative energy sources -- a faith in alternatives, ironically, as strong as some of the early advocates for nuclear power in the 1950s.

Fukushima and the Doomsday Clock

Kennette Benedict

When dreadful events occur, reporters, readers, and interested citizens contact the Bulletin of the Atomic Scientists asking whether we will move the minute hand of the Doomsday Clock. The alarming nuclear disaster at the Fukushima Daiichi Power Station on March 11 prompted e-mails and calls to our office seeking the Bulletin's reaction as well as accurate information about what was happening in Japan.

The Fukushima tragedy demonstrates that nuclear energy doesn't make sense

Arjun Makhijani

From the time we learn to walk, mistakes are inherent in the process of human learning. An essential design principle for technology should be that we, the generations that benefit, should bear the major costs of its mistakes. Nuclear power fails this simple test miserably.

The uncertainty surrounding sustainable agriculture

Laura H. Kahn

All of our planet's problems began 10,000 to 15,000 years ago with the domestication of livestock and crops, and it went downhill from there. While agriculture provided a stable food supply, it also required the destruction of pristine land. Surplus food enabled the growth of cities; cities led to civilizations; and civilizations eventually discovered the science and technology that allowed our numbers to grow. And, while these advances have been great for us humans, they haven't been so great for the natural world.
