Published Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve
(via sciencedaily.com)
Original source 
Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.
Published Physicists discover transformable nano-scale electronic devices
(via sciencedaily.com)
Original source 
The nano-scale electronic parts in devices like smartphones are solid, static objects that once designed and built cannot transform into anything else. But physicists have reported the discovery of nano-scale devices that can transform into many different shapes and sizes even though they exist in solid states.
Published Coastal species persist on high seas on floating plastic debris
(via sciencedaily.com)
Original source 
The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.
Published Environmental toxin PCB found in deep sea trench
(via sciencedaily.com)
Original source 
Researchers on a deep-sea expedition have found PCB in sediment samples from the more than 8,000-meter-deep Atacama Trench in the Pacific Ocean.
Published Researchers successfully establish a strong mechanical bond of immiscible iron and magnesium
(via sciencedaily.com)
Original source 
Transport relies heavily on steel. But steel is heavy, and scientists are turning to alternatives to lessen the transportation industry's carbon emissions. Magnesium alloys are one such alternative. But developing bonding technology that bonds magnesium alloys with structural steels has been severely limited because magnesium and iron are immiscible. Now, a research group has established a dealloying bonding technology that obtains a strong mechanical bond between iron and magnesium.
Published Less ice, fewer calling seals
(via sciencedaily.com)
Original source 
For several years, a team of researchers used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings indicate that sea-ice retreat has had significant effects on the animals' behavior: when the ice disappears, areas normally full of vocalizations become very quiet.
Published New approach estimates long-term coastal cliff loss
(via sciencedaily.com)
Original source 
A new method for estimating cliff loss over thousands of years in Del Mar, California, may help reveal some of the long-term drivers of coastal cliff loss in the state.
Published Processing data at the speed of light
(via sciencedaily.com)
Original source 
Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Gentle method allows for eco-friendly recycling of solar cells
(via sciencedaily.com)
Original source 
By using a new method, precious metals can be efficiently recovered from thin-film solar cells. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells.
Published Chemists redesign biological PHAs, 'dream' biodegradable plastics
(via sciencedaily.com)
Original source 
They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.
Published Predictive power of climate models may be masked by volcanoes
(via sciencedaily.com)
Original source 
Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study.
Published Luminous molecules
(via sciencedaily.com)
Original source 
Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are smoothing the path for new and better light sources.
Published Your fork could someday be made of sugar, wood powders and degrade on-demand
(via sciencedaily.com)
Original source 
Single-use hard plastics are all around us: utensils, party decorations and food containers, to name a few examples. These items pile up in landfills, and many biodegradable versions stick around for months, requiring industrial composting systems to fully degrade. Now, researchers have created a sturdy, lightweight material that disintegrates on-demand -- and they made it from sugar and wood-derived powders.
Published Pollution monitoring through precise detection of gold nanoparticles in woodlice
(via sciencedaily.com)
Original source 
Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.
Published Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions
(via sciencedaily.com)
Original source 
Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com)
Original source 
Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published Scientists use peroxide to peer into metal oxide reactions
(via sciencedaily.com)
Original source 
Researchers to get a better look at how peroxides on the surface of copper oxide promote the oxidation of hydrogen but inhibit the oxidation of carbon monoxide, allowing them to steer oxidation reactions.
Published Toward tunable molecular switches from organic compounds
(via sciencedaily.com)
Original source 
Newly synthesized organic molecules can be tuned to emit different colors depending on their molecular structures in crystal form.

(via sciencedaily.com)
Original source 
In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes -- potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.
Published Long-forgotten equation provides new tool for converting carbon dioxide
