Ice-free preservation method holds promise to protect reefs      (via sciencedaily.com) 

An interdisciplinary team of researchers demonstrated that coral can be preserved through a new technique called isochoric vitrification. This process takes the selected coral fragments through the stages of cryopreservation and subsequent revival.

Researchers unearth a new process by which algae pass on nurtrients to their coral host      (via sciencedaily.com) 

Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.

Barnacles may help reveal location of lost Malaysia Airlines flight MH370      (via sciencedaily.com)     Original source 

Geoscientists have created a new method that can reconstruct the drift path and origin of debris from flight MH370, an aircraft that went missing over the Indian Ocean in 2014 with 239 passengers and crew.

This fish doesn't just see with its eyes -- it also sees with its skin      (via sciencedaily.com)     Original source 

Without a mirror, it can be hard to tell if you're blushing, or have spinach in your teeth. But one color-changing fish has evolved a clever way to keep watch on the parts of itself that lie outside its field of view -- by sensing light with its skin.

Scientists explore dinosaur 'Coliseum' in Denali National Park      (via sciencedaily.com)     Original source 

Scientists have discovered and documented the largest known single dinosaur track site in Alaska. The site, located in Denali National Park and Preserve, has been dubbed 'The Coliseum' by researchers.

Key role of ice age cycles in early human interbreeding      (via sciencedaily.com)     Original source 

Recent paleogenomic research revealed that interbreeding was common among early human species. However, little was known about when, where, and how often this hominin interbreeding took place. Using paleoanthropological evidence, genetic data, and supercomputer simulations of past climate, a team of international researchers has found that interglacial climates and corresponding shifts in vegetation created common habitats for Neanderthals and Denisovans, increasing their chances for interbreeding and gene flow in parts of Europe and central Asia.

Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells      (via sciencedaily.com)     Original source 

With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.

Microplastics found embedded in tissues of whales and dolphins      (via sciencedaily.com)     Original source 

Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student's study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics can travel out of the digestive tract and lodge in the tissues.

Gray whales that spend their summers feeding off the coast of Oregon are shorter than their counterparts who travel north to the Arctic for food, new research shows.

Top fish predators could suffer wide loss of suitable habitat by 2100 due to climate change      (via sciencedaily.com)     Original source 

A study of 12 species of highly migratory fish predators -- including sharks, tuna, and billfish such as marlin and swordfish -- finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.

Protected sex: Grouper mating calls in marine managed areas      (via sciencedaily.com)     Original source 

Groupers produce distinct sounds associated with courtship, territoriality or reproduction. An autonomous mobile wave glider and passive acoustics were deployed to survey two marine protected areas on the western shelf of Puerto Rico to locate spawning aggregations of two commercially important species -- the Nassau and red hind groupers. Findings show these sites are critical habitat for both species and multiple previously unknown grouper species, which highlight the importance of expanding existing seasonal regulations.

The oldest and fastest evolving moss in the world might not survive climate change      (via sciencedaily.com)     Original source 

A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

Land-sea relationship is major driver of coral reef health outcomes      (via sciencedaily.com)     Original source 

New research indicates that mitigating both local land and sea-based human impacts, especially in terms of pollutants and over-fishing, provides coral reef ecosystems with the best opportunity to persist under climate change. Along some highly populated areas on the shorelines of Hawai'i, wastewater pollution and urban runoff combine with fishing pressures to put immense stress on coral reefs.
