• Scientists probe link between magnetic polarity reversal and mantle processes

    Updated: 2012-07-31 15:00:37
    Scientists at the University of Liverpool have discovered that variations in the long-term reversal rate of the Earth's magnetic field may be caused by changes in heat flow from the Earth's core into the base of the overlying mantle. read more

    Updated: 2012-07-29 19:30:06
    After the fall of the Soviet Union twenty years ago, water distribution in Central Asia became a source of conflict. In areas where summer precipitation is low, glaciers play an important role when considering the quantity of available water. The Tien Shan region is a prime example; mountain glaciers in this region contribute significantly to the fresh water supply in the arid zones of Kyrgyzstan, Kazakhstan, Uzbekistan, Turkmenistan, and Northwestern China. Like Switzerland, Kyrgyzstan serves as a water tower for its neighboring countries.read more

  • Cutting the graphene cake

    Updated: 2012-07-29 18:31:04
    Sandwiching individual graphene sheets between insulating layers in order to produce electrical devices with unique new properties, the method could open up a new dimension of physics research. Writing in Nature Materials, the scientists show that a new side-view imaging technique can be used to visualize the individual atomic layers of graphene within the devices they have built. They found that the structures were almost perfect even when more than 10 different layers were used to build the stack. read more

  • Chronic 2000-04 drought, worst in 800 years, may be the 'new normal'

    Updated: 2012-07-29 18:30:18
    CORVALLIS, Ore. – The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the "new normal" for most of the coming century. Such climatic extremes have increased as a result of global warming, a group of 10 researchers reported today in Nature Geoscience. And as bad as conditions were during the 2000-04 drought, they may eventually be seen as the good old days.read more

  • Spontaneous symmetry breaking and Higgs excitations

    Updated: 2012-07-28 16:54:48
    Phase transitions between different states of matter can be associated with a specific type of excitation called the "Higgs excitation". This phenomenon has now been observed in a two-dimensional quantum gas at temperatures near absolute zero. In physics, spontaneous symmetry breaking is a fundamental feature of transitions between different states of matter. An example of this phenomenon is the abrupt alignment of spin orientation in a ferromagnetic substance when the material is cooled below the so-called Curie temperature.read more

  • Martian polygons and deep-sea polygons on Earth: More evidence for ancient Martian oceans?

    Updated: 2012-07-28 16:53:00
    lorado, USA - Debate over the origin of large-scale polygons (hundreds of meters to kilometers in diameter) on Mars remains active even after several decades of detailed observations. Similarity in geometric patterns on Mars and Earth has long captured the imagination. In this new article from GSA Today, geologists at The University of Texas at Austin examine these large-scale polygons and compare them to similar features on Earth's seafloor, which they believe may have formed via similar processes. read more

  • Nano Fourier transform infrared spectroscopy and modern analytical chemistry

    Updated: 2012-07-28 16:52:00
    An ultimate goal in modern chemistry and materials science is the non-invasive chemical mapping of materials with nanometer scale resolution. A variety of high-resolution imaging techniques exist (e.g. electron microscopy or scanning probe microscopy), however, their chemical sensitivity cannot meet the demands of modern chemical nano-analytics. Optical spectroscopy, on the other hand, offers high chemical sensitivity but its resolution is limited by diffraction to about half the wavelength, thus preventing nanoscale resolved chemical mapping. read more

  • Snakes and Dinosaurs

    Updated: 2012-07-27 10:28:54
    27 July 2012 Further study by scientists of a fossil specimen originally found over 100 years ago has revealed a new type of snake that would have lived at the same time as T rex. Named Coniophis the snake is an exciting find as it is a transitional species showing features of both snakes and lizards. Coniophis is 60 centimetres long and has the body of a snake and the head of a lizard. 70 million years ago Coniophis could easily have slithered around the feet of T rex and other dinosaur. It was a burrowing snake and is unlikely to have been preyed on by dinosaurs. It was not poisonous as this is something that did not develop until much later in snake evolution.

    ANN ARBOR, Mich.—Researchers trying to herd tiny particles into useful ordered formations have found an unlikely ally: entropy, a tendency generally described as "disorder." Computer simulations by University of Michigan scientists and engineers show that the property can nudge particles to form organized structures. By analyzing the shapes of the particles beforehand, they can even predict what kinds of structures will form. read more

  • Dino-vandals strike in Canada

    Updated: 2012-07-26 12:41:55
    26 July 2012 Palaeontologists have been sickened and outraged by another attack of dinosaur vandalism in Alberta. A well-preserved Hadrosaur was being excavated by a team lead by Philip Currie. On leaving the site for Canada Day celebrations at the end of June the palaeontologists covered the specimen with plaster to protect it and then camouflaged it with dirt. On returning the site had been attacked and the plaster ripped away and the bones were shattered and scattered around. This is the third recorded case of vandalism concerning fossil excavations. A pachyrinosaurus suffered a similar fate. The vandalism is ruining invaluable scientific fossil specimens that could further our knowledge of dinosaurs and their behaviour. Its pointlessness shocks everyone.

    TORONTO, July 25, 2012 – A new study by York University researchers finds that songbirds follow a strict annual schedule when migrating to their breeding grounds – with some birds departing on precisely the same date each year. The study, published in the journal PLoS ONE, is the first to track the migration routes and timing of individual songbirds over multiple years. Researchers outfitted wood thrushes with tiny geolocator "backpacks," recording data on their movements. read more

The Alpine Fault is the most hazardous fault on the South Island of New Zealand, and about 80 miles northwest of the South Island's main city of Christchurch. read more

  • Study shows economic feasibility for capturing carbon dioxide directly from the air

    Updated: 2012-07-24 15:00:20
    With a series of papers published in chemistry and chemical engineering journals, researchers from the Georgia Institute of Technology have advanced the case for extracting carbon dioxide directly from the air using newly-developed adsorbent materials. The technique might initially be used to supply carbon dioxide for such industrial applications as fuel production from algae or enhanced oil recovery. But the method could later be used to supplement the capture of CO2 from power plant flue gases as part of efforts to reduce concentrations of the atmospheric warming chemical. read more
