Researchers at the KAUST Red Sea Research Center have sequenced the genome of Zostera marina, the very first marine flowering plant ever to receive the treatment. Their findings shed light on how the species adapted from the deep to seas to shallow ponds and back again over hundreds of millions of years. Read about the research on EurekAlert!.

Video: After reviewing more than 52 hours of octopus footage, researchers at Alaska Pacific University and University of Sydney are challenging the prevailing notion that octopi use their color-changing abilities only to hide from predators. They describe a more nuanced interpretation of octopi using color-changing along with body gestures as methods of social communication. Watch some of that video here and read about their research on EurekAlert!.

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.

A fishy tale of a sheep in wolf's clothing
Scientists have developed a technique to perform dietary analysis of fish by analyzing microscopic tooth wear. The results are published today, Dec. 11, 2015, in the journal Surface Topography: Metrology and Properties.

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.
