Geology
Where have all the craters gone?
Impact craters reveal one of the most spectacular geologic process known to man. During the past 3.5 billion years, it is estimated that more than 80 bodies, larger than the dinosaur-killing asteroid that struck the Yucatan Peninsula 66 million years ago, have bombarded Earth. However, tectonic processes, weathering, and burial quickly obscure or destroy craters. For example, if Earth weren't so dynamic, its surface would be heavily cratered like the moon or Mercury.

AGU: Experts publish new view of zone where Malaysia Airlines flight 370 might lie
A new illustration of the seafloor, created by two of the world's leading ocean floor mapping experts that details underwater terrain where the missing Malaysia Airlines flight might be located, could shed additional light on what type of underwater vehicles might be used to find the missing airplane and where any debris from the crash might lie.

New biodiversity study throws out controversial scientific theory
A research team led by Sean Connolly, ARC Centre of Excellence for Coral Reef Studies, has today released ground-breaking findings that dismiss the 'Neutral Theory of Biodiversity'. The theory has dominated biodiversity research for the past decade, and been advocated as a tool for conservation and management efforts. The study, the largest of its kind, covers a broad range of marine ecosystems on Earth and has important implications for how marine conservation areas are managed.

Climate change accelerates hybridization between native and invasive species of trout
Scientists have discovered that the rapid spread of hybridization between a native species and an invasive species of trout in the wild is strongly linked to changes in climate. Experts have long predicted that climate change could decrease worldwide biodiversity through cross-breeding between invasive and native species, but this study is the first to directly and scientifically support this assumption.

Scientists announce top 10 new species for 2014
An appealing carnivorous mammal, a 12-meter-tall tree that has been hiding in plain sight and a sea anemone that lives under an Antarctic glacier are among the species identified by the SUNY College of Environmental Science and Forestry's International Institute for Species Exploration as the top 10 species discovered last year.

Ka'ena Volcano: First building block for O'ahu discovered
Researcher John Sinton of the University of Hawai'i along with colleagues from the Monterrey Bay Aquarium and the French National Center for Scientific Research have announced the discovery of an ancient Hawaiian volcano. Now located in a region of shallow bathymetry extending about 100 km WNW from Ka'ena Point at the western tip of O'ahu, this volcano, which they have named Ka'ena, would have risen about 1,000 meters above sea level 3.5 million years ago.

Scientist uncovers links connecting environmental changes with spike in infectious disease
Smithsonian scientist Bert Van Bocxlaer and a team of researchers revealed that anthropogenic changes in Africa's Lake Malaŵi are a driving force behind the increase of urogenital schistosomiasis, a debilitating disease caused by parasitic flatworms. In some villages along Lake Malaŵi, 73 percent of people and up to 94 percent of schoolchildren are infected. The research suggests the spike in infection is linked to an increase in human populations and agricultural activities near Lake Malaŵi.

Dam removal improves shad spawning grounds, may boost survival rate
Research from North Carolina State University finds that dam removal improves spawning grounds for American shad and seems likely to improve survival rates for adult fish, juveniles and eggs -- but for different reasons.

Humpback whale subspecies revealed by genetic study
A new genetic study has revealed that populations of humpback whales in the oceans of the North Pacific, North Atlantic and Southern Hemisphere are much more distinct from each other than previously thought, and should be recognized as separate subspecies. Understanding how connected these populations are has important implications for the recovery of these charismatic animals that were once devastated by hunting.

Bottom trawling causes deep-sea biological desertification
A study led by scientists from the Polytechnic University of Marche -- Ancona, Italy -- involving researchers from the Institute of Marine Sciences and the Autonomous University of Barcelona, has determined that fishing trawling causes intensive, long-term biological desertification of the sedimentary seabed ecosystems, diminishing their content in organic carbon and threatening their biodiversity.

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.

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.'
