Scientists are drawing inspiration from plants to develop new techniques to separate and extract valuable minerals, metals and nutrients from resource-rich wastewater.

High-severity wildfire in California's Sierra Nevada forests has nearly quintupled compared to before Euro-American settlement, rising from less than 10% per year then to up to 43% today, a new study finds.

Five years after the deadliest and most destructive wildfire in California history, researchers document persistent differences in cognitive function among survivors.

Seasonal temperature, moisture loss from plants and wind speed are what primarily drive fires that sweep across the same landscape multiple times, a new study reveals. These findings and others could help land managers plan more effective treatments in areas susceptible to fire, particularly in the fire-ravaged wildland-urban interfaces of California.

A new study shows that smoke particles from human-lit fires are responsible for over 80% of smoke-related deaths each year. The study shows that smoke pollution is on the rise, reducing air quality, and leading to increased illness and premature deaths.

A new kind of solar panel has achieved 9% efficiency in converting water into hydrogen and oxygen--mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.

Chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous, capable of harvesting water from the air for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare.

A new study found bird diversity increased in North Carolina mountain forest areas severely burned by wildfire in 2016, reinforcing that while wildfire can pose risks to safety and property, it can be beneficial to wildlife. The study results could help forest managers better predict bird responses to wildfire, and manage forests to benefit birds.

U.S. firms rarely report their wildfire risks in required federal filings and instead bury such risks in nonspecific risk disclosures, according to new research.

Researchers have shown how nitrogen fertilizer could be produced more sustainably. This is necessary not only to protect the climate, but also to reduce dependence on imported natural gas and to increase food security.

Researchers analyzed the effects of decarbonization strategies by linking global resource inventories with demographic systems to generate a matrix showing the risks and benefits. The research suggests that increased demand for energy transition metals (ETMs) could be more disruptive to some communities than winding back production of thermal coal. The team calculated that while a complete phase-out of coal could disrupt mine-town systems with a minimum of 33.5 million people, an additional 115.7 million would be at risk from disruption by ETMs.

Researchers have been studying the effects of the sudden decrease in global temperatures that occurred about 8,200 years ago, the so-called 8.2-kiloyear event, with the help of mineral deposits present in White Moon Cave in Northern California. New indications show that oscillations between extreme wetness and aridity in California were closely linked with the occurrence of wildfires. The researchers have concluded that such events are likely to become more common in the face of human-induced climate change.

Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves -- and moving towards dangerous wildfires and warmer temperatures, says one of the largest studies of U.S. migration and natural disasters. These results are concerning, as wildfire and rising temperatures are projected to worsen with climate change. The study was inspired by the increasing number of headlines of record-breaking natural disasters.

Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.

A new study finds that the health benefits associated with wind power could more than quadruple if operators turned down output from the most polluting fossil-fuel-based power plants when energy from wind is available. However, compared to wealthier communities, disadvantaged communities would reap a smaller share of these benefits.

A new social media-based study of recreation visitation in the Gorge following the Eagle Creek Fire expands on research launched in 2016 -- and holds promise for other large, multi-ownership landscapes. The study shows how using new approaches that draw from social media data can help us better understand the complex relationships between wildfire, natural resource management, and people.

Greater atmospheric demand for water means a dramatic increase in the risk of major fires in global forests unless we take urgent and effective climate action, new research finds. Researchers have examined global climate and fire records in all of the world's forests over the last 20 years.

An interdisciplinary team of researchers has developed a potential breakthrough in green aviation: a recipe for a net-zero fuel for planes that will pull carbon dioxide (CO2) out of the air.

As strong winds and torrential rains inundate Australia's south-eastern coast, new research suggests that high intensity bushfires might not be too far behind, with their dual effects extending damage zones and encroaching on previously low-risk residential areas.

New research shows a pathway toward full decarbonization of U.S. aviation fuel use by substituting conventional jet fuel with sustainably produced biofuels. The study found that planting the grass miscanthus on 23.2 million hectares of existing marginal agricultural lands -- land that often lays fallow or is poor in soil quality -- across the United States would provide enough biomass feedstock to meet the liquid fuel demands of the U.S. aviation sector fully from biofuels, an amount expected to reach 30 billion gallons/year by 2040.
