Scientists are watching an iceberg bigger than the island of Guam as it slowly moves away from an Antarctic glacier. Don’t worry: it’s more a wonder than a worry and is not a threat to shipping or sea level rise.
Researchers studying the Amazon Basin have revealed unprecedented details of the size, age and...
A new study suggests that rising and falling sea levels played a key role in the distribution of...
A mineralogy researcher has discovered a new mineral that is unique in structure and composition among the world's 4,000 known mineral species.
Scientists have long been trying to understand how the Andes and other broad, high-elevation mountain ranges were formed. New research shows that the Altiplano plateau in the central Andes— and most likely the entire mountain range— was formed through a series of rapid growth spurts.
A geostatistical approach for studying environmental conditions in stream networks and landscapes has been successfully applied at a valley-wide scale to assess headwater stream chemistry at high resolution, revealing unexpected patterns in natural chemical components.
A study has found that— despite fears of a biodiversity crisis— there has, in fact, not been a consistent drop in numbers of species found locally around the world.
Asteroid and comet impacts can cause widespread ecological havoc, killing off plants and animals on regional or even global scales. But, new research shows that impacts can also preserve the signatures of ancient life at the time of an impact.
Some of the landscape underlying the massive Greenland ice sheet may have been undisturbed for 2.7 million years, ever since the island became completely ice-covered, according to researchers.
The first study that combines different scales into one model to simulate the effects of Asian pollution on the Pacific storm track has shown that the pollution can influence weather over much of the world. These results show that using multiple scales in one model greatly improves the accuracy of climate simulations.
Bacillus anthracis, the bacteria that causes anthrax, is commonly found in soils all over the world and can cause serious, often fatal, illness in both humans and animals. Now, a credit card-sized anthrax detection cartridge makes testing safer, easier, faster and cheaper.
Predicting when a volcano will blow its top takes constant monitoring. Researchers are now looking to satellites as a valuable eye in the sky, since they can observe the ground around volcanoes for signs of deformation.
Researchers have shown that humic substances act as fully regenerable electron acceptors which helps explain why large amount of methane are held in wetlands instead of being released to the atmosphere. However, there are worries that if this system is disrupted it may release large amounts of methane back into the atmosphere.
A new book attempts to offer a reader-friendly, unbiased, scientific guide needed to make well-informed decisions regarding energy use and, more specifically, hydraulic fracturing in the Marcellus Shale.
Researchers are collaborating around the globe for a special Earth Day experience on Tuesday, April 22, designed to capture up to 1 million natural sound recordings and upload them for preservation.
Portland officials say they are flushing away millions of gallons of treated water, for the second time in less than three years, because someone urinated into a city reservoir.
In August 2011, thousands of dead red abalone washed up on the beaches of Sonoma County in Northern California. At the time, the cause was unknown. Now, scientists, using a new approach called forensic genomics, have learned that a harmful algal bloom was to blame: the causative agent Yessotoxin.
The proportion of land used to cultivate shade grown coffee, relative to the total land area of coffee cultivation, has fallen by nearly 20 percent globally since 1996. Researchers say the global shift toward a more intensive style of coffee farming is probably having a negative effect on the environment, communities and individual farmers.
We can learn a lot about volcanoes by studying explosions. The more we can learn about their explosive behavior, the more chance we have of saving lives when they suddenly erupt.
The soil on Mars may be suitable for cultivating food crops. In a unique pilot experiment, a scientist tested the growth of 14 plant varieties on artificial Mars soil over 50 days. To his surprise, the plants grew well; some even blossomed.
A study has found some cause for optimism: ozone levels in the Arctic haven’t yet sunk to the extreme lows seen in Antarctica, in part because international efforts to limit ozone-depleting chemicals have been successful.
Forests growing in fertile soils, with ample nutrients, are able to sequester about 30 percent of the carbon they take up during photosynthesis. In contrast, forests growing in nutrient-poor soils may retain only 6 percent of that carbon.
The headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest’s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.
Scientists first discovered that some sponges are carnivorous about 20 years ago. Since then only seven carnivorous species have been found in all of the northeastern Pacific. Now, a paper describes four new species of carnivorous sponges living on the deep seafloor, from the Pacific Northwest to Baja California.
Ecologists say findings from a collaboration that spans four continents can improve our understanding of hydropower and will benefit fish around the globe.
An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the Earth’s climate.
A federal appeals court says the Environmental Protection Agency acted reasonably in deciding not to change the primary air quality standard for carbon monoxide.
