 Nature{DISSERTATION} Scientists 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 {DISSERTATION} 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.

Science{DISSERTATION} World'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.

BioScience{DISSERTATION} Natural '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 ONE{DISSERTATION} Frog 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 Earth{DISSERTATION} Penn 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.

The world's most common disease transmitted to humans by animals, according to the World Health Organization, leptospirosis is a two-phase disease that begins with flu-like symptoms but can cause meningitis, liver damage, pulmonary hemorrhage, renal failure, and even death if untreated.

Nature Communications{DISSERTATION} Making 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.

Nature{DISSERTATION} Carnivorous plant throws out 'junk' DNA The newly sequenced genome of the carnivorous bladderwort plant provides surprising insight into noncoding 'junk' DNA, a mysterious genetic material that makes up about 98 percent of the human genome and much of the genomes of other species. The bladderwort genome has almost no junk: 97 percent consists of genes and small control regions, showing that vast quantities of noncoding 'junk' DNA are not needed for complex life to exist.

{DISSERTATION} UC Riverside entomologist receives $566,000 grant to study ant parasitoids Entomologist John Heraty at the University of California, Riverside has received a three-year $566,000 grant from the National Science Foundation to study a group of wasps that specialize as parasitoids of ants. Ants' often large, complex societies are built around feeding and nurturing the egg-laying queen and protecting their brood from a tremendous array of natural enemies. Few insects have been able to broach these formidable defenses. Eucharitid wasps are an exception.

The achievement is important news for nanoscale sensors and quantum computing.
