Published Next time you beat a virus, thank your microbial ancestors
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Less severe forest fires can reduce intensity of future blazes
(via sciencedaily.com) Original source Low- and moderate-severity forest wildfires can reduce the intensity of future fires, according to new research on 'reburns.'
Published Scientists discover phenomenon impacting Earth's radiation belts
(via sciencedaily.com) Original source Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm
(via sciencedaily.com) Original source On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source Researchers genetically modified poplar trees to produce high-performance, structural wood without the use of chemicals or energy intensive processing.
Published New research sheds light on relationships between plants and insects in forest ecosystems
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 The ancestor of all modern birds probably had iridescent feathers
(via sciencedaily.com) Original source 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 Mixed approach to reforestation better than planting or regeneration alone
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
Published Genome study informs restoration of American chestnut tree
(via sciencedaily.com) Original source Researchers use genomes to help restore the American chestnut population and adjust species breeding to the changing climate.
Published New dawn for space storm alerts could help shield Earth's tech
(via sciencedaily.com) Original source Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.
Published Hundreds of new genome sequences fill gaps in the fruit fly tree of life
(via sciencedaily.com) Original source A multitude of new genomic sequence data fills major gaps in the fruit fly tree of life, researchers report.
Published Discovery of a hybrid lineage offers clues to how trees adapt to climate change
(via sciencedaily.com) Original source The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.
