New research links chemical changes in seawater to volcanic activity and changes.

Geoscientists have long thought that water -- along with shallow magma stored in Earth's crust -- drives volcanoes to erupt. Now, thanks to newly developed research tools, scientists have learned that gaseous carbon dioxide can trigger explosive eruptions.

Scientists have discovered that the breakup of tectonic plates is the main driving force behind the generation and eruption of diamond-rich magmas from deep inside the Earth.

The research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that they installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain's electrical activity during the immersive VR interactions.

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period.

Kama?ehuakanaloa (formerly L??ihi Seamount), a submarine Hawaiian volcano located about 20 miles off the south coast of the Big Island of Hawai'i, has erupted at least five times in the last 150 years, according to new research led by Earth scientists at the University of Hawai'i at M?noa.

An international drilling expedition off the Norwegian coast confirms the theory that methane emissions from hydrothermal vents were responsible for global warming about 55 million years ago. The study shows that the vents were active in very shallow water depth or even above sea level, which would have allowed much larger amounts of methane to enter the atmosphere.

A chemical process used in the browning of food to give it its distinct smell and taste is probably happening deep in the oceans, where it helped create the conditions necessary for life. Known as the Maillard reaction after the French scientist who discovered it, the process converts small molecules of organic carbon into bigger molecules known as polymers. In the kitchen, it is used to create flavors and aromas out of sugars. But a research team argues that on the sea floor, the process has had a more fundamental effect, where it has helped to raise oxygen and reduce carbon dioxide levels in the atmosphere, to create the conditions for complex life forms to emerge and thrive on Earth.

Researchers have analyzed the shifting patterns of entire dune fields on Earth and Mars, as seen from orbit, and found they are a direct signature of recent environmental change. This new tool can be applied anywhere with dunes, such as Mars, Titan, and Venus.

Earth's oldest craters could give scientists critical information about the structure of the early Earth and the composition of bodies in the solar system as well as help to interpret crater records on other planets. But geologists can't find them, and they might never be able to, according to a new study.

Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.

Engineers have designed a new, shape-shifting display that can fit on a card table and allows users to draw 3D designs and more.

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.

Much of central Utah's seismic activity comes in groups of small earthquakes. A study by seismologists examines 2,300 quakes occurring 40 'swarms' dating back to 1981, opening a window into Earth's crust in a geothermally active area.

In a new study, researchers have found that the restoration efforts of the critically endangered species elkhorn coral depend largely on the animal's location, microbiome, and the right conditions to provide an abundance of food.

What should the city we live in look like? How do structural changes affect the people who move around it? Cartographers use virtual reality tools to explore these questions before a great deal of money is spent on building measures. Using the Unity3 game engine, they recreate scenarios in 3D where people can experience potential changes through immersion. They were able to prove that the physical reaction to this experience is measurable.

New research describes a continuous roller printing approach that can precisely transfer thousands of microscopic semiconductor devices in a single shot. This method paves the way to creating large-scale arrays of optical components and could be used to rapidly manufacture micro-LED displays.
