New data gathered by the Mars Curiosity rover indicates a potential history of hydrothermal activity on the red planet, broadening the variety of habitable conditions once present there, scientists report in a new study. Researchers found concentrations of the elements zinc and germanium to be 10 to 100 times greater in sedimentary rocks in Gale Crater compared to the typical Martian crust.
Researchers report in a new study that a carbon compound called iron carbide, combined with small amounts of silicon impurities, may be an important component of the inner core. The researchers performed computer simulations to model how an iron and nickel core containing either iron carbide, or iron carbide with some silicon, compares to the density and other known characteristics of the inner core.

Extremely low oxygen levels in Earth’s oceans could be responsible for extending the effects of a mass extinction that wiped out millions of species on Earth around 200 million years ago, according to a new study.

Using acoustic footage of a volcanic eruption and images taken by a remotely operated vehicle (ROV), scientists have documented an underwater volcano’s eruption off the coast of El Hierro, the smallest of the Canary Islands.

Sea level rise hot spots — bursts of accelerated sea rise that last three to five years — happen along the U.S. East Coast thanks to a one-two punch from naturally occurring climate variations, a new study shows.

Small ocean waves could play a bigger role in breaking up ice shelves than tsunamis or other large waves, a new study suggests. A new study examining vibrations in Antarctica’s Ross Ice Shelf finds small waves continuously impacting the ice shelf may create enough strain to extend existing cracks in the ice and potentially create new ones. An ocean wave of 1 centimeter (0.5 inches) in height can cause vibrations that repeatedly move the ice more than 20 centimeters (8 inches).

How will future disasters affect countries in Eastern Europe and Central Asia? Researchers aiming to answer this question used projected changes in population and Gross Domestic Product (GDP) for 33 countries, along with climate, flood and earthquake risk models, to estimate how each country is affected by flooding and earthquakes now and in the future. In addition, the earthquake model was used to estimate fatalities and capital losses from a strong quake.

A new study has identified the climate variation patterns which exert the most influence on atmospheric river activity along the West Coast. One of these patterns is the long-term increasing trend associated with Pacific Ocean warming likely due to human activity.

As the CFCs slowly degrade over the coming decades, so too should the volcano’s ozone-destroying power. However, new research shows that the volcanic risk to the ozone layer will persist for decades longer than previously believed.

Acidified water draining from abandoned mines, studied primarily as a modern environmental hazard, may offer insight into the oxygenation of Earth’s early atmosphere and development of life on other planets, according to a new study.
