Published Engineers develop an efficient process to make fuel from carbon dioxide



Researchers developed an efficient process that can convert carbon dioxide into formate, a nonflammable liquid or solid material that can be used like hydrogen or methanol to power a fuel cell and generate electricity.
Published The importance of the Earth's atmosphere in creating the large storms that affect satellite communications



Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.
Published 3D printed reactor core makes solar fuel production more efficient



Using a new 3D printing technique, researchers have developed special ceramic structures for a solar reactor. Initial experimental testing show that these structures can boost the production yield of solar fuels.
Published Alpine rock reveals dynamics of plate movements in Earth's interior



Examining how plates move in Earth's mantle and how mountains form is no easy feat. Certain rocks that have sunk deep into Earth's interior and then returned from there can deliver answers.
Published Mystery of volcanic tsunami solved after 373 years



The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo's underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only be described by a combination of a landslide followed by an explosive eruption.
Published Venus had Earth-like plate tectonics billions of years ago, study suggests



Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past and the history of the solar system.
Published Superdeep diamonds provide a window on supercontinent growth



Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research. These findings demonstrate that superdeep diamonds can provide a window through space and time into the supercontinent growth and formation process.
Published Researchers probe molten rock to crack Earth's deepest secrets



An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its magnetic behavior and reactivity in chemical reactions, and can influence whether iron prefers to be in the molten or solid rock.
Published California supervolcano is cooling off but may still cause quakes



New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.
Published Ancient diamonds shine light on the evolution of Earth



Formed millions to billions of years ago, diamonds can shine light into the darkest and oldest parts of the Earth's mantle. The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth. These diamonds that were formed between 650 and 450 million years ago on the base of the supercontinent Gondwana, were analysed by an international team of experts, and have shown how supercontinents such as Gondwana were formed, stabilised, and how they move around the planet.
Published Ice sheet surface melt is accelerating in Greenland and slowing in Antarctica



Surface ice in Greenland has been melting at an increasing rate in recent decades, while the trend in Antarctica has moved in the opposite direction, according to researchers.
Published The effects of preheating on vehicle fuel consumption and emissions appear minimal



A new study found that the benefits of car preheating for both fuel economy and emissions are minimal. The researchers focused on vehicle fuel consumption and emissions under cold winter conditions. Of particular interest were cold start emissions and their relation to preheating.
Published Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate



Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. The team had predicted its existence over 10 years ago based on fragments of old tectonic plates found deep in the Earth’s mantle. To the lead researchers surprise, she found that oceanic remnants on northern Borneo must have belonged to the long-suspected plate, which scientists have named Pontus. She has now reconstructed the entire plate in its full glory.
Published Climate change brings earlier arrival of intense hurricanes



New research has revealed that since the 1980s, Category 4 and 5 hurricanes (maximum wind speed greater than 131 miles per hour) have been arriving three to four days earlier with each passing decade of climate change.
Published Discovery made about Fischer Tropsch process could help improve fuel production



A fundamental discovery about the Fischer Tropsch process, a catalytic reaction used in industry to convert coal, natural gas or biomass to liquid fuels, could someday allow for more efficient fuel production. Researchers discovered previously unknown self-sustained oscillations in the Fischer Tropsch process. They found that unlike many catalytic reactions which have one steady state, this reaction periodically moves back and forth from a high to a low activity state. The discovery means that these well-controlled oscillatory states might be used in the future to control the reaction rate and the yields of desired products.
Published Ancient carbon in rocks releases as much carbon dioxide as the world's volcanoes



New research has overturned the traditional view that natural rock weathering acts as a carbon sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivaling that of volcanoes.
Published Volcanic ash effects on Earth systems



To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range.
Published Discovery of massive undersea water reservoir could explain New Zealand's mysterious slow earthquakes



Researchers working to image New Zealand's Hikurangi earthquake fault have uncovered a sea's worth of water buried in the Earth's crust. The water was carried down by eroding volcanic rocks and is believed to be dampening the earthquake fault, allowing it to release most of the pent-up tectonic stress through harmless slow slip earthquakes.
Published Ancient plant wax reveals how global warming affects methane in Arctic lakes



In a new study, researchers examined the waxy coatings of leaves preserved as organic molecules within sediment from the early-to-middle Holocene, a period of intense warming that occurred due to slow changes in Earth's orbit 11,700 to 4,200 years ago. They found that warming potentially could lead to a previously under-appreciated flux in methane emissions from lakes.
Published Scientists unveil fire-safe fuel



Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.
