North Korea tests “smaller and lighter” bomb

This morning North Korea announced that it had conducted a third underground nuclear weapons test. The test was detected by US Geologic Survey seismic monitoring stations and those of the Comprehensive Test Ban Treaty Organisation in Vienna, which reported “explosion-like characteristics”. The yield of the test is believed to be between roughly 3 and 10 kilotonnes, according to James Acton, a physicist at the Carnegie Endowment for International Peace in Washington, DC.  Read more

External review reaffirms hurdles for nuclear-fusion superlaser

If looks could trigger thermonuclear fusion....

Last autumn, the world’s most powerful laser missed a major milestone in its drive to produce thermonuclear fusion. Now the findings of an independent peer-review panel lay out in detail why achieving that goal is turning out to be so difficult.  Read more

ITER gets a home

ITER gets a home

The experimental ITER reactor is supposed to show how to do nuclear fusion here on earth. So far, however, it’s been used by many scientists as an example of how not to do a major scientific project. The roughly €15 billion (US$ 19.9 billion) project has been parcelled into contracts, which in turn have been divided among ITER’s seven members: the European Union, Russia, Japan, South Korea, India, China and the United States. As we reported in autumn, this piecemeal strategy is threatening to delay ITER’s already delayed start date by years while the central organisation and member states parcel out designs and contracts.  Read more

Fukushima fish still hot

Fukushima fish still hot

Data visualization is all the rage these days, but there’s nothing quite like getting the story from points on a graph. In today’s issue of Science, Ken Buesseler of the Wood’s Whole Oceanographic Institution in Massachusetts provides plots of radioactivity in fish around the ruined Fukushima Daiichi nuclear plant that do just that (click image to enlarge).  Read more
