Restricting nuclear power has little effect on the cost of climate policies

  • PDF
TechAndComputer (Oct. 1, 2012) — By applying a global energy-economy computer simulation that fully captures the competition between alternative power supply technologies, a team of scientists analyzed trade-offs between nuclear and climate policies. Strong greenhouse-gas emissions reduction to mitigate global warming shows to have much larger impact on economics than nuclear policy, according to the study. Incremental costs due to policy options restricting the use of nuclear power do not significantly increase the cost of even stringent greenhouse-gas emissions reductions.

"Questions have been raised if restricting nuclear energy -- an option considered by some countries after the accident in Fukushima, Japan -- combined...

Simulations uncover 'flashy' secrets of merging black holes

  • PDF
Supercomputer models of merging black holes reveal properties that are crucial to understanding future detections of gravitational waves. This still image is from a movie that follows two orbiting black holes and their accretion disk during their final three orbits and ultimate merger. Redder colors correspond to higher gas densities.

Finding the statistical fingerprints of election thieves

  • PDF
In fair elections, a nation's voting pattern tends to feature one cluster, showing a general trend of voter turnout and vote for the victorious party (though some nations' regional voter preferences can distort it). Rigged ones show a cluster, but with a smear of votes toward the upper right for incremental fraud. Extreme fraud has a second, smaller, completely separate cluster at the top right corner, signifying up to 100 percent turnout and votes for the winner. (Credit: Image...

'Blue Brain' project accurately predicts connections between neurons

  • PDF
Scientists have identified key principles that determine synapse-scale connectivity by virtually reconstructing a cortical microcircuit and comparing it to a mammalian sample. These principles now make it possible to predict the locations of synapses in the neocortex. (Credit: Image courtesy of Ecole Polytechnique Fédérale de Lausanne)
