Mapping downgoing plate topography: The 2005 Sumatra earthquake
New geophysical data show that fault slip during the March 2005 magnitude 8.7 (Mw) earthquake off the west coast of northern Sumatra, Indonesia (also referred to as the Simeulue-Nias earthquake), was stopped by the topography on the downgoing plate.

Functions of global ocean microbiome key to understanding environmental changes
The billions of marine microorganisms present in every liter of seawater represent a structured ecological community that regulates how the Earth functions in practically every way, from energy consumption to respiration. The function and behavior of this community will determine how the global ocean responds to broader environmental changes, according to a new review article published in the journal Science by University of Georgia marine scientist Mary Ann Moran.

CRISPR-Cas9 helps uncover genetics of exotic organisms
A revolutionary gene-editing tool is transforming the study of standard lab animals like the fruit fly, but could have even greater impact in genetic studies of more exotic animals, like the octopus or sea anemone. UC Berkeley scientists used CRISRP-Cas9 to quickly and efficiently knock out six Hox genes in the amphipod, revealing one example of how segmented animals deploy different limbs on different segments, like tools in a Swiss army knife.

US Pacific Northwest's extreme rainfall tallied by NASA's IMERG
As moisture from the tropics has been streaming into the Pacific Northwest by the 'Pineapple Express' NASA's Global Precipitation Measurement mission and a cadre of other satellites have been gathering data on the extreme rainfall. The continued 'training' of rainfall into the area has caused flooding in the Portland, Oregon area with at least one death reported. Western Washington is also on flood alert due to the deluge.

Scientists discover 530-million-year-old fossils of ancient, microscopic worms
The historic find -- made in South China -- by Virginia Tech researchers fills a huge gap in the known fossil record of kinorhynchs, small invertebrate animals that are related to arthropods.

The need to name all forms of life
Only a fifth of the nine million species of animal, plant and fungus thought to occur on earth is known. Dragonflies (which include damselflies) are seen as well-known. Nonetheless researchers describe 60 newly discovered species, the greatest number of new dragonflies in about a century.

Save the salamanders
Batrachochytrium salamandrivorans (Bsal) is an emerging fungal pathogen that has caused recent die-offs of salamanders in Europe. Laboratory experiments have shown that it can kill some North American species as well, confirming a serious threat to salamander populations on the continent.

How skates and rays got their wings
The evolution of the striking, wing-like pectoral fins of skates and rays relied on repurposed genes, according to new research by scientists from the University of Chicago. Studying embryonic skates, they discovered that the rear portion of the fin is built by typical limb-development genes; but the front portion develops through a different set of genes that are usually found in the shoulder areas of other species.

Study measures drag from fishing gear entanglements on North Atlantic right whales
In a paper published online Dec. 9, 2015, in Marine Mammal Science, a research team led by the Woods Hole Oceanographic Institution, has for the first time quantified the amount of drag on entangled whales that is created by towing fishing gear, such as rope, buoys, and lobster and crab traps. The study provides important data for teams evaluating the risks and benefits of whale disentanglements.

A DNA analysis of ballast water detects invasive species
The German research vessel Polarstern covers thousands of kilometers in search of samples of biological material. This ship, however, has some other on board passengers: organisms that can adapt to extreme water temperatures and could potentially invade the new waters where this ice breaker takes them. Upon analyzing the DNA present in this vessel's ballast water, a team of scientists showed the first molecular evidence of the persistence of DNA belonging to a tiny sea snail which is capable of tolerating adverse conditions.

Air pollutions control policies effective in improving downwind air quality
Emissions controls on coal-fired power plants are making a difference in reducing exposure of mercury to people, especially in the western Maryland community. A study of air quality from the University of Maryland Center for Environmental Science found that levels of mercury in the air from power plant emissions dropped more than half over a 10-year period, coinciding with stricter pollution controls.

Coral reefs could be more vulnerable to coastal development than predicted
For years, many scientists thought we had a secret weapon to protect coral reefs from nutrients flushed into the seas by human activity. Experiments suggested that herbivores such as fish, urchins and sea turtles could keep corals and their ecosystems healthy by eating up extra algae that grew in the presence of these nutrients. But a new University of Florida study sheds doubt on that idea, underscoring the importance of sustainable growth in coastal areas.

Microplastics: Rhine one of the most polluted rivers worldwide
Between Basel and Rotterdam, the Rhine has one of the highest microplastics pollution so far measured in rivers, with the Rhine-Ruhr metropolitan area showing peak numbers of up to four times the average. Among investigated rivers, the Rhine is thus among those most heavily polluted with microplastics. This is reported by researchers from the University of Basel. Their results have been published in the journal Scientific Reports.

Planners aim for coastal growth in all the right places
When it comes to helping coastal communities be more resilient to weather hazards, ideas don't need to be sandbagged, experts say. That's why the Federal Emergency Management Agency has granted $750,000 to a program that already is experienced in working with city leaders along the Texas coast and other Gulf states.

Ocean toxicity hampered the rapid evolution of complex life
By examining rocks at the bottom of ancient oceans, an international group of researchers have revealed that arsenic concentrations in the oceans have varied greatly over time. But also that in the very early oceans, arsenic co-varied with the rise of atmospheric oxygen and coincided with the coming and going of global glaciations. The study was recently published in the Nature Group Journal, Scientific Reports.
