Earth in the News
The latest reports of natural disasters and scientific discoveries about the Earth.
By analysing 138 experiments, researchers have mapped the potential of today's plants and trees to store extra carbon by the end of the century.
The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.
The tiny organisms cling to oil droplets and perform a great feat: As a single organism, they may produce methane from oil by a process called alkane disproportionation. Previously this was only known from symbioses between bacteria and archaea. Scientists have now found cells of this microbe called Methanoliparia in oil reservoirs worldwide.
When will we see significant changes in the ocean due to climate change? A new study finds that some changes are noticeable already, while others will take up to a century.
Computer models show why eruptive magma chambers tend to reside between six and 10 kilometers underground.
The existence of water in deep Earth is considered to play an important role in geodynamics, because water drastically changes the physical properties of mantle rock, such as melting temperature, electric conductivity, and rheological properties. Water is transported into deep Earth by the hydrous minerals in the subducting cold plates. Hydrous minerals, such as serpentine, mica and clay minerals, contain water in the form of hydroxyl (-OH) in the crystal structure. Most of the hydrous minerals decompose into anhydrous minerals and water when they are transported into deep Earth, at 40-100 km depth, due to the high temperature and pressure conditions.
With billions of years of practice, nature has created the most energy efficient machines. One, [Ne-Fi] hydrogenase, is the oldest in microorganisms and is used for hydrogen metabolism. Using Fourier transform infrared spectroscopy, researchers reveal the proton transfer pathway of this enzyme, a discovery expected to contribute to new biofuel cells.
Much of the planet sweltered in unprecedented heat in July, as temperatures soared to new heights in the hottest month ever recorded. The record warmth also shrank Arctic and Antarctic sea ice to historic lows.
Warmer winters are starting to alter the structure of the Black Sea, which could foreshadow how ocean compositions might shift from future climate change, according to new research.
Researchers have discovered that the numbers of plant species recorded by botanists have increased in locations where the climate has changed most rapidly, and especially in relatively cold parts of the world.
The Earth's carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate.
In a 19-year study, scientists dug roughly 6 feet down to compare soil carbon changes in different cropping systems. They found that compost is a key to storing carbon, a strategy for offsetting carbon dioxide emissions.
Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow -- and even in such remote regions as the Arctic and Alps.
Researchers are setting out to find answers to disappearance of famed pilot Amelia Earhart. An autonomous surface vehicle (ASV), or robot, can explore the seafloor in waters that may be too deep for divers.
A new review of silicon cycling in glacial environments highlights the potential importance of glaciers in exporting silicon to downstream ecosystems.
Researchers are paving the way toward greater safety for coastal residents and infrastructure by developing a better means of modeling the destructive force of tsunami waves.
Research revealed a unique feeding strategy of a marine sponge, wherein the sponge animal acquires important components of its diet from symbiotic bacteria living within the sponge.
As methane concentrations increase in the Earth's atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new research.
About 35 million years ago, an asteroid hit the ocean off the East Coast of North America. Its impact formed a 25-mile diameter crater that now lies buried beneath the Chesapeake Bay. A team of researchers has obtained drilling samples from the Ocean Drilling Project site 1073 and dated them with the ''uranium-thorium-helium technique'' for the first time.
Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study.
