A wetter world recorded in Australian coral colony      (via sciencedaily.com)     Original source 

When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.

Eyes open and toes out of water: How a giant water bug reached the island of Cyprus      (via sciencedaily.com)     Original source 

A new visitor was reported on the coast of Cyprus, thanks to the growing power of citizen science. Researchers collected information and specimens through personal communication with amateur naturalists, but also through the internet, in order to compose the mosaic of repeated appearances of a giant water bug on the eastern shoreline of the island.

Why do tree frogs lay their eggs on the ground?      (via sciencedaily.com)     Original source 

A curious aspect of tree frogs is that they often lay their eggs on the ground where the risk of predation by natural enemies is greater than in the trees where they live. A research team suggested that the reason for this behavior is to protect the eggs from low temperatures. Their findings highlight the challenge faced by tree frogs: Should they attempt to maintain an optimal temperature for their eggs or risk predation?

Even inactive smokers are densely colonized by microbial communities      (via sciencedaily.com)     Original source 

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

Surprising insights about debris flows on Mars      (via sciencedaily.com)     Original source 

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study.

Unique way to track carbon emissions in bodies of water      (via sciencedaily.com)     Original source 

Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide. As many states look for cost-effective ways to mitigate climate change, scientists looked at a way to optimize CO2 sensors to better measure carbon dioxide emissions in lotic, or moving, bodies of water offering a new tool that can help provide valuable information for everything from land use to climate action plans.

Sulfur and the origin of life      (via sciencedaily.com)     Original source 

A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.

With discovery of roundworms, Great Salt Lake's imperiled ecosystem gets more interesting      (via sciencedaily.com)     Original source 

Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.

Drought, soil desiccation cracking, and carbon dioxide emissions: an overlooked feedback loop exacerbating climate change      (via sciencedaily.com)     Original source 

Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.

Grounding zone discovery explains accelerated melting under Greenland's glaciers      (via sciencedaily.com)     Original source 

Researchers have conducted the first large-scale observation and modeling study of northwest Greenland's Petermann Glacier. Their findings reveal the intrusion of warm ocean water beneath the ice as the culprit in the accelerated melting it has experienced since the turn of the century, and their computer predictions indicate that potential sea level rise will be much worse than previously estimated.

Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation      (via sciencedaily.com)     Original source 

Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
