Published Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species
(via sciencedaily.com) Original source Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.
Published Chemists create organic molecules in a rainbow of colors
(via sciencedaily.com) Original source Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.
Published Top 10 climate science insights unveiled
(via sciencedaily.com) Original source A new report equips policymakers with the latest and most pivotal climate science research from the previous 18 months, synthesized to help inform negotiations at COP28 and policy implementation through 2024 and beyond.
Published From infamy to ingenuity: Bacterial hijack mechanisms as advanced genetic tools
(via sciencedaily.com) Original source Researchers have uncovered the intricate molecular mechanism used by parasitic phytoplasma bacteria, known for inducing 'zombie-like' effects in plants.
Published Using AI to find microplastics
(via sciencedaily.com) Original source An interdisciplinary research team is using artificial intelligence (AI) to identify microplastics faster and more accurately than ever before.
Published Wildfires have erased two decades' worth of air quality gains in western United States
(via sciencedaily.com) Original source A new study concludes that wildfires originating in the western United States and Canada have erased air quality gains over the past two decades and caused an increase of premature deaths in fire-prone areas and downwind regions, primarily in the western U.S.
Published Fossil CO2 emissions at record high in 2023
(via sciencedaily.com) Original source Global carbon emissions from fossil fuels have risen again in 2023 -- reaching record levels, according to new research.
Published Recycling concrete using carbon can reduce emissions and waste
(via sciencedaily.com) Original source Amid the rubble of large-sale earthquake, war or other disaster -- and as ageing buildings and infrastructure are replaced -- mountains of concrete are often taken to landfill or pounded into rubble for roads. For a more sustainable approach, experts are developing a 'value add' for old broken concrete to 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient -- graphene.
Published In hotter regions, mammals seek forests, avoid human habitats
(via sciencedaily.com) Original source As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.
Published Strange burn: New research identifies unique patterns in Utah wildfires
(via sciencedaily.com) Original source Utah's variable topography produces a tremendous range of wildfire behavior, according to new research.
Published New study identifies the greatest threat to wildlife across North America and Canada: people
(via sciencedaily.com) Original source A biology student studied more than 600,000 wildlife rehabilitation center records to look at the human impact on wild animals, from lead poisonings to window strikes to vehicle collisions.
Published 1.5°C pathways can still be achieved, combining fairness and global climate protection
(via sciencedaily.com) Original source Global warming can still be limited to 1.5°C by 2100 while ensuring that the poor are not hit hardest by climate policies and climate impacts. This is achieved by immediately introducing broad carbon pricing together with re-distributive policies using carbon pricing revenues and further measures to reduce energy consumption, accelerate technological transitions, and transform the land sector.
Published How mountains affect El Niño-induced winter precipitation
(via sciencedaily.com) Original source A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests.
Published Snail-inspired robot could scoop ocean microplastics
(via sciencedaily.com) Original source Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes.
Published Artificial light is luring birds to cities and sometimes to their deaths
(via sciencedaily.com) Original source Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.
Published More than a meteorite: New clues about the demise of dinosaurs
(via sciencedaily.com) Original source What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.
Published Researchers decode aqueous amino acid's potential for direct air capture of CO2
(via sciencedaily.com) Original source Scientists have made a significant stride toward understanding a viable process for direct air capture, or DAC, of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions, where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.
Published Himalayan glaciers react, blow cold winds down their slopes
(via sciencedaily.com) Original source Himalayan Glaciers fight back to preserve themselves, but for how long? An international team of researchers explains a stunning phenomenon: rising global temperatures have led Himalayan glaciers to increasingly cool the air in contact with the ice surface. The ensuing cold winds might help cool the glaciers and preserve the surrounding ecosystems. The results were found across the Himalayan range.
Published New technique efficiently offers insight into gene regulation
(via sciencedaily.com) Original source Researchers have developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease. MAbID offers new insights into how these mechanisms work together or against each other.
Published Botany must feature more prominently on the school curriculum to promote awareness of climate change, study warns
(via sciencedaily.com) Original source Children must be taught more about the importance of plants if education about climate change and sustainability is to be effective, experts have warned.
