New Analysis Reveals Large-Scale Motion Around San Andreas Fault System

117953_web.jpg

An array of GPS instruments near the San Andreas Fault System in Southern California detects constant motion of Earth's crust--sometimes large, sudden motion during an earthquake and often subtle, creeping motion. By carefully analyzing the data recorded by the EarthScope Plate Boundary Observatory's GPS array researchers from the University of Hawai'i at Mānoa (UHM), University of Washington and Scripps Institution of Oceanography (SIO) discovered nearly 125 mile-wide "lobes" of uplift and subsidence--a few millimeters of motion each year--straddling the fault system. This large scale motion was previously predicted in models but until now had not been documented.

'Space Tsunami' Causes the Third Van Allen Belt

118011_web.jpg

Earth's magnetosphere, the region of space dominated by Earth's magnetic field, protects our planet from the harsh battering of the solar wind. Like a protective shield, the magnetosphere absorbs and deflects plasma from the solar wind which originates from the Sun. When conditions are right, beautiful dancing auroral displays are generated. But when the solar wind is most violent, extreme space weather storms can create intense radiation in the Van Allen belts and drive electrical currents which can damage terrestrial electrical power grids. Earth could then be at risk for up to trillions of dollars of damage.

Where Were You Born? Origin Matters for Species Interactions

0609_VOLKER-beetles115-lg-2c0abf6_1.jpg

An oft-quoted proverb says it takes a village to raise a child, and new research from ecologists at LSU and Rice University suggests that a similar concept may be at work in natural ecosystems. The research, which appears in this week’s Early Edition of the Proceedings of the National Academy of Sciences, finds that the early life experiences of individual animals can have wide-reaching impacts on entire species.

Camouflage Influences Life-and-Death Decisions That Animals Make

Nesting birds time their escape from an approaching predator depending on how well camouflaged their eggs and their own bodies are, researchers from the University of Exeter and the University of Cambridge have discovered.

Study Finds Link Between 2015 Melting Greenland Ice, Faster Arctic Warming

Finding the Real Treasure of the Incas: Two New Frog Species From an Unexplored Region

116786_web.jpg

Inaccessibility and mysticism surrounding the mist-veiled mountains of the central Andes make this region promising to hide treasures. With an area of 2197 km2, most of the Llanganates National Park, Ecuador, is nearly unreachable and is traversed only by foot. However, fieldwork conducted by researchers from the Museo de Zoología at Catholic University of Ecuador resulted in the discovery of a more real and tangible gem: biodiversity.

Evolution Painted Onto Butterfly Wings

116760_web.jpg

Using a reverse paint-by-numbers approach, scientists have located another gene that controls the brilliant patterning of Heliconius butterfly wings. Led by former Smithsonian Tropical Research Institute (STRI) fellow Nicole Nadeau, the researchers identified variations in the gene that correspond to wing color and pattern variation in three different Heliconius species.
