Published New gels could protect buildings during wildfires



Researchers have developed a sprayable gel that creates a shield to protect buildings from wildfire damage. It lasts longer and is more effective than existing commercial options.
Published Next time you beat a virus, thank your microbial ancestors



When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research, two key elements of our innate immune system came from a group of microbes called Asgard archaea.
Published Environmental laws failing to slow deforestation



Australia's environmental laws are failing to stop high rates of tree clearing to make way for agriculture, development and mining.
Published 'Masters of shape-shifting': How darkling beetles conquered the world



Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
Published Action plan to help patients with lung disease cope with wildfire smoke



A multidisciplinary team has developed an action plan to help patients with respiratory diseases mitigate the consequences of poor air quality from wildfires.
Published Less severe forest fires can reduce intensity of future blazes



Low- and moderate-severity forest wildfires can reduce the intensity of future fires, according to new research on 'reburns.'
Published Climate change raised the odds of unprecedented wildfires in 2023-24



Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts



A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
Published Mature forests vital in frontline fight against climate change



Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.
Published New genetically engineered wood can store carbon and reduce emissions



Researchers genetically modified poplar trees to produce high-performance, structural wood without the use of chemicals or energy intensive processing.
Published Canadian wildfires are affecting US air quality and raising health concerns



Climate-driven wildfire events are rapidly transferring harmful particulate matter containing toxic chemicals over long distances, compromising air quality in the New Jersey and New York City areas, according to recent research.
Published New York City's fireworks display prompts temporary surge of air pollution



In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before, according to the results of a new study.
Published New research sheds light on relationships between plants and insects in forest ecosystems



Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage



Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published California a botanical and climate change hot spot



Climate-driven shifts in California's biodiversity call for innovation and continued environmental stewardfship, says a new study. California's 30x30 Initiative and efforts to harmonize biodiversity with renewable energy are promising steps, while wildfire strategies need to further adapt.
Published The ancestor of all modern birds probably had iridescent feathers



Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published Solar absorption by black carbon in fire clouds quantified



Aerosol scientists quantify the extent of light absorption by black carbon in fire clouds to better model climate impacts of extreme wildfire events.
Published Mixed approach to reforestation better than planting or regeneration alone



Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.
Published How well does tree planting work in climate change fight? It depends



Using trees as a cost-effective tool against climate change is more complicated than simply planting large numbers of them, an international collaboration has shown.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere



Tree bark surfaces play an important role in removing methane gas from the atmosphere.
