The mystery of what kick-started the motion of our earth's massive tectonic plates across its surface has been explained by researchers at the University of Sydney.
"Earth is the only planet in our solar system where the process of plate tectonics occurs," said Professor Patrice Rey, from the University of Sydney's School of Geosciences.
Washington, DC— A team of researchers working on a Carnegie expedition in Australia's Great Barrier Reef has documented that coral growth rates have plummeted 40% since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown.
New research has found that the Great Barrier Reef, as a whole, is a remarkably effective wave absorber, despite large gaps between the reefs. This means that landward of the reefs, waves are mostly related to local winds rather than offshore wave conditions.
As waves break and reduce in height over reefs, this drives currents that are very important for the transport of nutrients and larvae. This reduction in wave height also has implications for shoreline stability.
Alexandria, Va. — Most people are familiar with the Great 1906 San Francisco Earthquake and are aware of the earthquake risk posed to the Bay Area — and much of California — by the San Andreas Fault. Most people are not aware, however, that a cluster of large earthquakes struck the San Andreas and quite a few nearby faults in the 17th and 18th centuries. That cluster, according to new research, released about the same amount of energy throughout the Bay Area as the 1906 quake.

A complex web of interaction between viruses, bacteria, and their environment is becoming ever more untangled by a growing international collaboration between Matthew Sullivan, associate professor in the University of Arizona's Department of Ecology and Evolutionary Biology and Steven Hallam from the University of British Columbia in Vancouver, Canada.
WASHINGTON, Sept. 15, 2014 — By now, we've got all the details about Apple's latest iPhone, and the lines are probably forming somewhere for the Sept. 19 launch. But what do you really know about the guts of the iPhone 6, or any smartphone for that matter? Reactions teamed up once again with the Compound Interest blog to reveal the chemical elements found inside your smartphone. Learn all about it at http://youtu.be/66SGcBAs04w.
Tropical Storm Odile continues to drench western Mexico and has now entered into the U.S. Southwest. On September 15, NASA's Terra satellite saw Odile's northernmost edge crossing the Mexican border into southern California. NOAA's GOES-East satellite on September 16 showed Odile's outer bands were already bringing storms to southern Arizona.

Irvine, Calif., Sept. 16, 2014 – UC Irvine chemists have scored a scientific first: capturing moving images of a single molecule as it vibrates, or "breathes," and shifts from one quantum state to another.
The groundbreaking achievement, led by Ara Apkarian, professor of chemistry, and Eric Potma, associate professor of chemistry, opens a window into the strange realm of quantum mechanics – where nanoscopic bits of matter seemingly defy the logic of classical physics.
WASHINGTON D.C., September 16, 2014 – A team of researchers at Boston University and Stanford University School of Medicine has developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony.
WASHINGTON, D.C., September 16, 2014 – Researchers from the University of Alabama in Huntsville and the University of Oklahoma have found a new way to control the properties of quantum dots, those tiny chunks of semiconductor material that glow different colors depending on their size. Quantum dots, which are so small they start to exhibit atom-like quantum properties, have a wide range of potential applications, from sensors, light-emitting diodes, and solar cells, to fluorescent tags for biomedical imaging and qubits in quantum computing.
WASHINGTON, D.C., September 16, 2014 --The emerging field of molecular electronics could take our definition of portable to the next level, enabling the construction of tiny circuits from molecular components. In these highly efficient devices, individual molecules would take on the roles currently played by comparatively-bulky wires, resistors and transistors.
A team of NOAA researchers today confirmed the discovery just outside San Francisco's Golden Gate strait of the 1910 shipwreck SS Selja and an unidentified early steam tugboat wreck tagged the "mystery wreck." The researchers also located the 1863 wreck of the clipper ship Noonday, currently obscured by mud and silt on the ocean floor.
