Published Sugar permeation discovered in plant aquaporins
(via sciencedaily.com) Original source Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.
Published Deep sea sensor reveals that corals produce reactive oxygen species
(via sciencedaily.com) Original source A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
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 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 Decoding flavonoid metabolism: A closer look at plant-based diets
(via sciencedaily.com) Original source An international team of researchers has elucidated the process by which the major flavonoids naringenin, apigenin, and genistein are metabolized in the body. These findings are fundamental in elucidating the correlation between the metabolism of flavonoids in the body and their potential health benefits.
Published Public gardens contribute to invasives problem
(via sciencedaily.com) Original source Some nonnative plants cultivated in public gardens or arboretums are escaping to become invasive in wild forests.
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.
Published Genomic study sheds light on how carnivorous Asian pitcher plants acquired signature insect trap
(via sciencedaily.com) Original source Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
Published Snake skulls show how species adapt to prey
(via sciencedaily.com) Original source By studying the skull shapes of dipsadine snakes, researchers have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources.
Published Unsafe lead levels in school drinking water: new study IDs building risk factors
(via sciencedaily.com) Original source Civil and environmental engineers have determined the factors that may help identify the schools and daycare centers at greatest risk for elevated levels of lead in drinking water. The most telling characteristic for schools in Massachusetts is building age, with facilities built in the 1960s and 1970s -- nearly a third of the facilities tested -- at the greatest risk for having dangerously high water lead levels.
Published Money to burn: Wealthy, white neighborhoods losing their heat shields
(via sciencedaily.com) Original source White, wealthy neighborhoods in the LA area -- and likely around the world -- are about to start feeling the same heat that has plagued poorer, Hispanic neighborhoods for generations. A new study shows the protective effect of income has largely eroded over the past 40 years, as landscape plants can't keep up with the pace of climate warming.
Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com) Original source Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published how far can the wind can carry a plant's seeds? New model
(via sciencedaily.com) Original source Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.
Published Small marine creatures swimming in plastic chemicals not reproducing
(via sciencedaily.com) Original source Plastic waste in the water might be stopping -- or interrupting -- some shrimp-like creatures from reproducing. In a unique study, the ability of 'shrimp like' creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.
Published Durable plastic pollution easily, cleanly degrades with new catalyst
(via sciencedaily.com) Original source Found in fishing nets, carpet, clothing, Nylon-6 is a major contributor to plastic pollution, including ocean pollution. Now, chemists have developed a new catalyst that quickly, cleanly and completely breaks down Nylon-6 in a matter of minutes -- without generating harmful byproducts. Even better: The process does not require toxic solvents, expensive materials or extreme conditions, making it practical for everyday applications. In experiments, the new process recovered 99% of the polymer's building blocks, which can then be upcycled into higher-value products.
Published A new bacterial species from a hydrothermal vent throws light on their evolution
(via sciencedaily.com) Original source A new bacterial species discovered at the deep-sea hydrothermal vent site 'Crab Spa' provides a deeper understanding of bacterial evolution.
Published 600 years of tree rings reveal climate risks in California
(via sciencedaily.com) Original source The San Joaquin Valley in California has experienced vast variability in climate extremes, with droughts and floods that were more severe and lasted longer than what has been seen in the modern record, according to a new study of 600 years of tree rings from the valley.
Published Blasts to clear World War II munitions could contaminate the ocean
(via sciencedaily.com) Original source World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.
