 Nature MaterialsKinks and curves at the nanoscale Since 2004, materials scientists and nanotechnology experts have been excited about a special of arrangement of atoms called a "coherent twin boundary" that can add enormous strength to metals like gold and copper. The CTBs are described as "perfect," appearing like a one-atom-thick plane in models and images. New research shows that these boundaries are not perfect. Even more surprising, the newly discovered kinks and defects appear to be the cause of the CTB's strength.

Nature GeoscienceSea level influenced tropical climate during the last ice age The Indo-Pacific warm pool was much dryer during the last ice age than today, because lower sea level exposed the Sunda Shelf. The large landmass, in place of the warm ocean, altered the atmospheric circulation, shifting convection further west into the Indian Ocean. These findings by scientists at the International Pacific Research Center, University of Hawaii at Manoa, and Woods Hole Institute of Oceanography, appear in the May 19, online edition of Nature Geoscience.

Nature BiotechnologyComputational tool translates complex data into simplified 2-dimensional images Researchers at Columbia University and Stanford University have developed a computational method that enables scientists to visualize and interpret "high-dimensional" data produced by single-cell measurement technologies such as mass cytometry. The method, published today in the online edition of Nature Biotechnology, has particular relevance to cancer research and therapeutics.

The Carboniferous-Permian Transition ConferenceCracking the ice code UWM geologist John Isbell reads rock, looking for the natural rules that govern the Earth's climate in the absence of human activity. His work is challenging many assumptions about the ways drastic climate change unfolds -- and what to expect next.

Mathematicians analyze social divisions using cell phone data Human society fractures along lines defined by politics, religion, ethnicity, and perhaps most fundamentally, language. Although these differences contribute to the great variety of human lives, the partitions they create can lead to conflict and strife, impeding efforts toward social justice and economic development. David Meyer, a mathematician at UC San Diego, has developed a new way of understanding how characteristics like ethnicity and religion coincide to define communities and ultimately influence our actions.

NatureScientists capture first direct proof of Hofstadter butterfly effect A team of researchers from several universities – including UCF –has observed a rare quantum physics effect that produces a repeating butterfly-shaped energy spectrum in a magnetic field, confirming the longstanding prediction of the quantum fractal energy structure called Hofstadter's butterfly. This discovery by the team paves the way for engineering new types of extraordinary nanoscale materials that can be used to develop smaller, lighter and faster electronics, including sensors, cell phones, tablets and laptops.

Nanotechnology Moth-inspired nanostructures take the color out of thin films Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices.

ScienceWorld's melting glaciers making large contribution to sea rise While 99 percent of Earth's land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world's glaciers contributed just as much to sea rise as the two ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving the University Colorado Boulder.

BioScienceNatural 'keystone molecules' punch over their weight in ecosystems Ecosystems are disproportionately influenced by "keystone molecules" that have powerful behavioral effects and contribute to ecosystem structure, according to a general theory described in the June issue of BioScience. The chemicals can each fill a variety of functions and affect multiple species. The actions of four keystone molecules are described, three of them toxins.

PLOS ONEFrog once imported for pregnancy testing brought deadly amphibian disease to US, study suggests African frogs, originally imported for early 20th century pregnancy tests, carried a deadly amphibian disease to the US, according to findings published in PLOS ONE. African Clawed Frogs have long been suspected of spreading a harmful fungus called Batrachochytrium dendrobatidis. The earliest known case of the fungus was found in these frogs in their native South Africa. Now scientists have found the first evidence of the disease among introduced feral populations in the US.

Journal of Geophysical Research: Solid EarthPenn research helps paint finer picture of massive 1700 earthquake In 1700, a massive earthquake struck the west coast of North America, but a lack of local documentation has made studying this historic event challenging. Now, researchers from the University of Pennsylvania have helped unlock this geological mystery using a fossil-based technique. Their work provides a finer-grained portrait of this earthquake and the changes in coastal land level it produced, enabling modelers to better prepare for future events.

Nature CommunicationsMaking gold green: New non-toxic method for mining gold Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch -- instead of cyanide -- to isolate gold from raw materials in a selective manner. This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold.
