Similar proteins protect the skin of humans, turtles
Genes for important skin proteins arose in a common ancestor shared by humans and turtles 310 million years ago, a genome comparison has discovered.

Leatherback sea turtles choose nest sites carefully, study finds
The enormous, solitary leatherback sea turtle spends most of its long life at sea. After hatching and dispersing across the world's oceans, only the female leatherbacks return to their natal beaches to lay clutches of eggs in the sand. A new study offers fresh insights into their nesting choices and will help efforts to prevent the extinction of this globally endangered giant of the sea, researchers said.

Marine airgun noise could cause turtle trauma
Scientists are warning of the risks that seismic surveys may pose to sea turtles. Widely used in marine oil and gas exploration, seismic surveys use airguns to produce sound waves that penetrate the sea floor to map oil and gas reserves.

Whiffs from cyanobacteria likely responsible for Earth's oxygen
Earth's oxygen-rich atmosphere emerged in whiffs from a kind of cyanobacteria in shallow oceans around 2.5 billion years ago, according to new research.

Climate change: Warm water is mixing up life in the Arctic
The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait.

New camouflage mechanism fish use in the open ocean
Fish have a remarkable way to hide from their predators using camouflage techniques. A new study shows that fish scales have evolved to not only reflect light, but to also scramble polarization. Researchers identified the tissue structure that fish evolved to do this, which could be an analog to develop new materials to help hide objects in the water.

New vision for multifunctional materials
Taking a cue from nature, scientists have deciphered how the biomineral making up the body armor of a chiton mollusk has evolved to create functional eyes embedded in the animal's protective shell. The findings could help determine so far still elusive rules for generating human-made multifunctional materials.

Marine animals use new form of secret light communication
A new form of secret light communication used by marine animals has been discovered by scientists. The findings may have applications in satellite remote sensing, biomedical imaging, cancer detection, and computer data storage.

New project aims to develop advanced tools and research strategies for parasite control in European farmed fish
A new research project aims to improve our understanding of fish-parasite interactions and develop innovative solutions and tools to prevent, control and mitigate harmful parasites which affect the main fish species farmed in Europe (Atlantic salmon, rainbow trout, common carp, turbot, European sea bass, and gilthead sea bream).

Research using carbon dioxide keeps even small fry invasive carp at bay
Bubbling high concentrations of carbon dioxide into water is a deterrent to invasive Asian carp adults, researchers know. The gas makes them feel 'woozy' and they choose to swim away. New research shows that fish the size of an eyelash also experience negative consequences following carbon dioxide exposure.

How to catch a small squid? First records for the Gulf of California and southwest Mexico
Often avoiding sampling gear due to their capability to detect movements and swim their way out of the nets fast enough, the small squids living in the open-ocean zone have long gone under-researched. The present study seems to provide first and new distributional records of five such species for the Gulf of California and the southwestern coast of Mexico.

Low-oxygen 'dead zones' in North Pacific linked to past ocean-warming events
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led to vast marine dead zones.

Our closest wormy cousins: About 70% of our genes trace their ancestry back to the acorn worm
Scientists have analyzed the genomes of two acorn worm species and found that approximately two-thirds of human genes have counterparts in the ancestors of these marine animals. These ancient genes, and their organization within the genome, were already in place in the common ancestor of humans and acorn worms that lived over half a billion years ago.

New discovery may redefine classifications in the animal kingdom
A close cousin of the jellyfish has evolved over time into a microscopic parasite, new research shows. The finding represents the first case of extreme evolutionary degeneration of an animal body.

Marine fungi reveal new branches on tree of life
Researchers have discovered several new species of marine fungi inhabiting previously undescribed branches of the tree of life. Little is known about the fungi flourishing in the world's oceans and this study, which set out to investigate its diversity and abundance, revealed that many marine fungi are very different from those found on land.

Fat makes coral fit to cope with climate change
A year ago, researchers discovered that fat helps coral survive heat stress over the short term -- and now it seems that fat helps coral survive over the long term, too. The study offers important clues as to which coral species are most likely to withstand repeated bouts of heat stress, called 'bleaching,' as climate change warms world oceans.

Understanding seal movement can help mitigate seal-fishery conflict
Understanding the differences in the behavior of different seal species can help in the choice of the most effective measures to mitigate the seal-fishery conflict and in the sustainable management of seal stocks. A new study provides novel and detailed information of the movements of ringed seals and grey seals in the Baltic Sea. Researchers discovered that Baltic ringed seals range over large areas during the open water season, while most grey seals remain on smaller areas near their terrestrial resting sites.

Researchers sequence genomes of parasite that is actually a 'micro jellyfish'
Researchers have revealed how a jellyfish -- those commonplace sea pests with stinging tentacles -- have evolved over time into 'really weird' microscopic organisms, made of only a few cells, that live inside other animals.

Microbes that are key indicators of Puget Sound's health in decline
Paleontologists find that tiny organisms called foraminifera have a big story to tell about the health of Puget Sound. Two recent studies about the health of Bellingham Bay and inlets in the Bremerton area found the diversity and number of foraminifera -- single-celled marine organisms that live on the sea floor -- deteriorated significantly.

Loss of diversity near melting coastal glaciers
Melting glaciers are causing a loss of species diversity among benthos in the coastal waters off the Antarctic Peninsula, impacting an entire seafloor ecosystem. This has been verified in the course of repeated research dives, the results of which were recently published by experts from Argentina, Germany and Great Britain.
