From muscle loss to radiation exposure and the psychological effects of confinement, spaceflight takes a toll on those lucky enough to experience it.

Photocatalysts are useful materials, with a myriad of environmental and energy applications, including air purification, water treatment, self-cleaning surfaces, pollution-fighting paints and coatings, hydrogen production and CO2 conversion to sustainable fuels.

A key project in the restoration of the Everglades moved forward Thursday with the signing of an agreement between Florida and the federal government to construct a huge reservoir south of Lake Okeechobee.

A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests—cared for as "forest gardens"—contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators. The findings are published today in Ecology and Society.

A new machine-learning model that generates realistic seismic waveforms will reduce manual labor and improve earthquake detection, according to a study published recently in JGR Solid Earth.

Although many organisms capture and respond to sunlight, enzymes—proteins that catalyze biochemical reactions—are rarely driven by light. Scientists have identified only three types of natural photoenzymes so far. The newest one, discovered in 2017, is fatty acid photodecarboxylase (FAP). Derived from microscopic algae, it uses blue light to catalyze the conversion of fatty acids, found in...

It's not just the United States—other major polluters around the world have also been falling behind the climate goals they set for themselves under the Paris agreement.

As Earth Day is celebrated, Generation Z is grappling with the health of the planet and racism and social justice, according to a new survey.

SpaceX aimed to launch its third crew a little before sunrise Friday, this time using a recycled capsule and rocket.

A crew returned from the northernmost islands in the Hawaiian archipelago this week with a boatload of marine plastic and abandoned fishing nets that threaten to entangle endangered Hawaiian monk seals and other animals on the uninhabited beaches stretching more than 1,300 miles north of Honolulu.

As NASA's Perseverance rover begins its search for ancient life on the surface of Mars, a new study suggests that the Martian subsurface might be a good place to look for possible present-day life on the Red Planet.

Males may have shorter lifespans than females due to repetitive sections of the Y chromosome that create toxic effects as males get older. These new findings appear in a study by Doris Bachtrog of the University of California, Berkeley published April 22 in PLOS Genetics.

As part of the Paris Agreement, nearly all countries agreed to take steps to limit the average increase in global surface temperature to less than 2 degrees C, or preferably 1.5 degrees C, compared with preindustrial levels. Since the Agreement was adopted, however, concerns about global warming suggest that countries should aim for the "preferable" warming limit of 1.5 degrees C.

It seems like a smooth slab of stainless steel, but look a little closer, and you'll see a simplified cross-section of the Los Angeles sedimentary basin.

This week's climate change summit features lots of talk from different nations about their goals for reducing carbon emissions. But in the weird world of national climate pledges, numbers often aren't quite what they seem.

President Joe Biden on Thursday doubled US ambitions on slashing greenhouse gas emissions, leading Japan and Canada at a summit in making new commitments that bring the world closer to limiting the worst climate change.

Gov. Gavin Newsom on Wednesday declared a drought emergency in two Northern California counties as he stood on the dry shoreline of Lake Mendocino.

Japan aims to cut emissions 46 percent by 2030, significantly more than previously pledged, the country's prime minister announced Thursday ahead of a key US-hosted climate summit.

In the continuing search for dark matter in our universe, scientists believe they have found a unique and powerful detector: exoplanets.

Catalytic converters cut down on toxic car emissions, and, according to the U.S. Environmental Protection Agency, they're one of the greatest environmental inventions of all time.

Machine learning could provide up an extra hour of warning time for debris flows along the Illgraben torrent in Switzerland, researchers report at the Seismological Society of America (SSA)'s 2021 Annual Meeting.

Days after the 4 August 2020 massive explosion at the port of Beirut in Lebanon, researchers were on the ground mapping the impacts of the explosion in the port and surrounding city.

Research has identified critical factors that enable dangerous bacteria to spread disease by surviving on surfaces in hospitals and kitchens.

Product marketers should be clear in their messaging to avoid customer skepticism that makes them feel duped, according to University of Oregon research.
