Brain steroids make good dads
Insights from a highly social fish can help understand how other androgenic steroids, like testosterone, can shape a male's parenting skills, according to a recent Georgia State University research study.

Report finds site of mega-development project in Mexico is a biodiversity hotspot
Cabo Pulmo is a close-knit community in Baja California Sur, Mexico, and the best preserved coral reef in the Gulf of California. But the lands adjacent to the reef are under threat from a mega-development project, 'Cabo Dorado,' should construction go ahead. Scientists at the University of California, Riverside have published a report on the terrestrial biodiversity of the Cabo Pulmo region that shows the project is situated in an area of extreme conservation value.

The spot-tail golden bass: A new fish species from deep reefs of the southern Caribbean
Smithsonian scientists describe a new species of small coral reef sea bass from underexplored deep-reef depths of Curaçao, southern Caribbean. With predominantly yellow body and fins, the new species, Liopropoma santi, more closely resembles the other two 'golden basses' found together with it at Curaçao, L. aberrans and L. olneyi, than the striped species that occur on shallower reefs. The study was published in the open access journal ZooKeys.

How octopuses don't tie themselves in knots revealed by Hebrew University scientists
Hebrew University of Jerusalem researchers have discovered how octopuses avoid getting tangled up in themselves. Their results suggest that a chemical signal in octopus' skin inhibits sucker grabbing so that octopuses don't grab onto themselves. The researchers hope their findings will lead to new classes of robots and control systems, and are sharing their findings with European Commission project STIFF-FLOP, which aims to develop a flexible surgical manipulator in the shape of an octopus arm.

Antarctica's ice losses on the rise
Three years of observations show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year -- twice as much as when it was last surveyed.

Cutoff switch may limit spread, duration of oxygen minimum zones
A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that could lead to unchecked hypoxic areas, or persistent 'dead zones.'

Greenland will be far greater contributor to sea rise than expected
Greenland's icy reaches are far more vulnerable to warm ocean waters from climate change than had been thought, according to new research by UC Irvine and NASA glaciologists. The work, published today in Nature Geoscience, shows previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet.

On the shoulder of a giant: Precursor volcano to the island of O'ahu discovered
Researchers recently discovered that O'ahu, Hawai'i, actually consists of three major Hawaiian shield volcanoes, not two, as previously thought. Extending almost 100 km WNW from the western tip of the island of O'ahu is the submarine Ka'ena Ridge, a region that has now been recognized to represent a precursor volcano to the island of O'ahu, and on whose flanks the Wai'anae and Ko'olau Volcanoes later formed.

Richest marine reptile fossil bed along Africa's South Atlantic coast is dated at 71.5 million years ago
New research at Southern Methodist University, Dallas, is the first to tie the stable carbon isotope record of Africa's South Atlantic coast to global records. This record clarifies the age of rocks at Bentiaba, Angola. The work provides a 71.5 million year age for the richest marine reptile fossil bed along the South Atlantic. The new record of time represents nearly 30 million years of Cretaceous fossils and environments in the ancient South Atlantic Ocean.

Learning from sharks
Genetically engineered antibodies are deployed successfully in cancer diagnostics and therapy. Therapeutic antibodies against Alzheimer's disease and multiple sclerosis are currently under development. An important criterion when designing suitable antibody fragments is their stability. Comparing the antibodies of sharks with those of humans, a team of researchers at the Technische Universitaet Muenchen and the Helmholtz Zentrum Muenchen discovered stabilizing mechanisms that can also be applied to optimize custom-tailored antibodies for medical applications.

West Antarctic Ice Sheet collapse is under way

How octopuses don't tie themselves in knots
An octopus's arms are covered in hundreds of suckers that will stick to just about anything, with one important exception. Those suckers generally won't grab onto the octopus itself; otherwise, the impressively flexible animals would quickly find themselves all tangled up.

Extinct relative helps to reclassify the world's remaining 2 species of monk seal
The recently extinct Caribbean monk seal was one of three species of monk seal in the world. Its relationship to the Mediterranean and Hawaiian monk seals, both living but endangered, has never been fully understood. Through DNA analysis and skull comparisons Smithsonian scientists and colleagues have now clarified the Caribbean species' place on the seal family tree and created a completely new genus. The team's findings are published in the scientific journal ZooKeys.

Smithsonian scientists link unusual fish larva to new species of sea bass from Curacao
Identifying larval stages of marine fishes in the open ocean is difficult because the young fishes often bear little or no resemblance to the adults they will become. Confronted with a perplexing fish larva collected in the Florida Straits, Smithsonian scientists turned to DNA barcoding, which yielded an unexpected discovery -- a match between the mysterious fish larva and adults of a new species of sea bass discovered off the coast of Curacao.

Coral reefs are critical for risk reduction & adaptation
Stronger storms, rising seas, and flooding are placing hundreds of millions people at risk around the world, and big part of the solution to decrease those risks is just off shore. A new study finds that coral reefs reduce the wave energy that would otherwise impact coastlines by 97 percent.

A tiny, toothy catfish with bulldog snout defies classification
Kryptoglanis shajii is a strange fish -- and the closer scientists look, the stranger it gets. This small subterranean catfish sees the light of day and human observers only rarely, when it turns up in springs, wells and flooded rice paddies. Drexel scientists have recently provided a detailed description of this fish's bizarre bone structures.

Alcoholism: Clinical & Experimental Research
Follow that fish!
Research is helping unravel the complex interplay between alcohol and social behavior. In what may be the first experiment to allow ethanol-exposed and untreated zebrafish to swim freely together, those exposed to certain alcohol concentrations nearly doubled their swimming speeds when in a group--suggesting that the presence of peers substantially impacts social behavior. Most remarkably, unexposed fish modulated their behavior in the presence of a shoalmate exposed to alcohol.
