Guatemala's Pacaya volcano has been erupting since February, keeping local communities and authorities on high alert.

A new study by the University of Georgia revealed that more college students change majors within the STEM pipeline than leave the career path of science, technology, engineering and mathematics altogether.

A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.

The Earth's first forest fires appear to have occurred earlier than previously thought, pointing out a link between widespread wildfires and ancient tree evolution, according to researchers at The University of Alabama.

High levels of a naturally occurring chemical called arsenic have been a source of contamination of ground-based drinking water, such as well-water, for people in many countries around the world, including parts of the United States. Consuming arsenic-contaminated water is a serious public health issue, leading to severe health complications including skin, lung, bladder, kidney and liver cancers, according to the National Institute of Environmental Health Sciences.

When NASA's Ingenuity Mars Helicopter took to the Martian skies on its third flight on April 25, the agency's Perseverance rover was there to capture the historic moment. Now NASA engineers have rendered the flight in 3D, lending dramatic depth to the flight as the helicopter ascends, hovers, then zooms laterally off-screen before returning for a pinpoint landing. Seeing the sequence is a bit like standing on the Martian surface next to Perseverance and watching the flight firsthand.

Spacewalking is a major highlight of any astronaut's career. But there is a downside: putting on your spacesuit means sharing some previously-worn underlayers. A new ESA study is looking into how best to keep these items clean and hygienic as humans venture on to the Moon and beyond.

New collaborative research, led by the University of Oxford and published today in Ecological Solutions and Evidence, shows that a simple tropical forest assessment tool can robustly estimate forest condition, demonstrating high levels of agreement with detailed scientific data sets of biodiversity, forest structure and ecosystem functioning.

Mighty floods have carved out deep canyons on Earth. New research suggests this may have required less power than previously thought. Collecting such data, however, may be demanding.

A team of researchers affiliated with several institutions in the U.K. and one in Estonia has created a type of buoy that has proven to be effective at repelling seabirds, thus preventing them from getting caught in gillnets. In their paper published in the journal Royal Society Open Science, the group describes the buoy and how well it worked when tested.

In recent years, many material scientists worldwide have been investigating the potential of two-dimensional (2D) materials, which are composed of a single layer or a few ultrathin layers of atoms and have unique physical, electrical and optical properties.

Using the Harlan J. Smith Telescope, astronomers have discovered that the star HD 47127 has a substellar companion. The newly identified object, designated HD 47127 B, appears to be a brown dwarf or a brown dwarf binary. The finding is reported in a paper published May 4 on arXiv.org.
