Underwater volcanoes help form hydrothermal vents, which are formed due to converging plate boundaries. The vents are vital, as they hold biological molecules similar to enzymes and may suggest that they might hold life within them.
Three decades back in 1977, hydrothermal vents were first discovered near the Galapagos Islands. Not only the vents were found, a massive number of earlier unseen organisms were also discovered.

Scientists have uncovered a saltwater network 1,000 feet below an ice-free region McMurdo Dry Valleys in Antarctica. Some parts of the Antarctic region are quite similar to planet Mars and scientists recently discovered tunnels at Mars.
Researchers involved in the study said that the findings are important as the saltwater exists in a temperature that could support microbial life. For the research, electromagnetic sensor was used to find Antarctica's saltwater brines.

A massive eruption was noticed in Villarrica in Chile, sending lava hundreds of meters over the volcano’s summit crater, early Tuesday morning. Ash spread to the neighboring region shortly after the eruption. The intensity of the eruption was so great that the accompanying lava flow melted snow on the slopes of the volcano, leading to creation of some small volcanic mudflows and debris flows.
The eruption caused evacuation of nearly 3,500 people from the small towns around Villarrica, including the vacation town of Pucón.

Ice caves which drew huge public attention last year are back again in Leelanau County. In 2014, the ice caves that came into view on Lake Michigan were one of the biggest winter attractions around. Eric LePaugh, who lives in Glen Arbor, noticed the mounds forming on Lake Michigan. According to 'LePaugh, owner of Leelanau Adventures, mounds can be seen from the shore.
LePaugh also said that when he walked onto the frozen waters of Lake Michigan, he noticed numerous caves, but it was not as big as the ones from last year.

According to a new study, a tsunami caused by earthquake could raise water level up to 13 feet just inside the mouth of the Columbia River and about 7 feet within a few miles of Astoria. It was also found by Oregon State University engineers that rise in water level would be very small around Portland or Bonneville Dam.

The findings of a study recently conducted by the researchers at the University of Washington could change the belief how life actually evolved on earth.
The research focused upon nitrogen, which is considered to be a crucial ingredient of life. Scientists associated with the research believe that usable nitrogen had vey less supply during the early days of our planet.
University of Washington Earth and Space Sciences professor Roger Buick said in a statement that life on earth even before two billion years ago was thought to be very minute.

Deep inside an ice cap in the Peruvian Andes, scientists have traced air pollution from 16th-century Spanish silver mines. In an announcement made on Monday, scientists said the pollution appeared to have originated from what is now called Bolivia, located hundreds of miles away at the Potosí mountaintop silver mines. The imprint of metal-rich smog was actually discovered in Peru.

Researchers through a new research revealed that earthly aroma which is released at the beginning of the rain is due to the release of aerosol clouds that are carried by the winds.
The new study published this week in the journal Nature Communications stated that when raindrops land on certain porous surfaces, they capture tiny air bubbles containing small particles. These aerosols are most likely responsible for carrying the aromatic elements along with bacteria and viruses stored in the soil.

Around 20 homes situated along one of North Carolina's most fragile barrier islands will be saved by waves with the help of supersized sandbag wall that is being built there.
These homes are situated on Topsail Island's northern tip. The News & Observer of Raleigh reported that currently the crews are building a 9-foot-tall wall of sandbags to save these homes from collapsing. The allowance for this set up was given by state's Coastal Resources Commission because of the fact that the wall so constructed will be 3 feet taller than the maximum allowed height.
