When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere. A new study finds that these weak states have become more persistent over the past four decades and can be linked to cold winters in Russia and Europe.
The UK has low oil and gas resources and limited prospects for fracking, according to a new analysis by scientists at the University of Edinburgh, who recommend a shift towards greater use of renewable, clean energy.
The Cassini-Huygens mission to Saturn, a collaboration between NASA and the European Space Agency, is set to end on Sept. 15. The mission has told us a great deal about the unique and unexpected chemistry of Saturn's moon Titan, and it has changed the way we think about our own planet and the entire solar system.

Researchers led by Scripps Institution of Oceanography at the University of California San Diego have determined that major changes in plant behavior have occurred over the past 40 years, using measurements of subtle changes in the carbon dioxide (CO2) currently found in the atmosphere.
Slow slip events, a type of slow motion earthquake that occurs over days to weeks, are thought to be capable of triggering larger, potentially damaging earthquakes. In a new study led by The University of Texas at Austin, scientists have documented the first clear-cut instance of the reverse--a massive earthquake immediately triggering a series of large slow slip events.
Over the last 25 years, the world has seen an increased dependency on wind energy that promises to continue growing. This has created an ever-evolving process to develop a method that can accurately assess a region's wind energy potential. The European Union and other countries have begun development of the New European Wind Atlas, the details of which a Danish researcher discusses in this week's Journal of Renewable and Sustainable Energy.
A striking finding of the 2011 Tohoku-oki earthquake (Mw 9.0) is that more than 50 meters of coseismic fault slip reached the trench axis. In addition to this, seismological studies found a clear depth-dependent variation in the source location between high- and low-frequency seismic energy radiation. However, structural features that may control the slip behavior in the rupture zone have not been well examined.
'Primordial black holes,' believed to have formed shortly after the Big Bang, might explain how heavy elements such as gold, platinum and uranium came to be, UCLA physicists report.
An extreme global warming event 56 million years ago was driven by massive carbon dioxide emissions from volcanoes, suggests a new study led by the University of Southampton.
The sudden, unexpected nosedive in Antarctic sea ice last year was due to a unique one-two punch from atmospheric conditions both in the tropical Pacific Ocean and around the South Pole.
