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 Crocodile family tree mapped: New light shed on croc evolution
(via sciencedaily.com) Original source Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
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 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 Consensus needed on when global warming reaches 1.5°C
(via sciencedaily.com) Original source A team of scientists has emphasized that -- surprisingly -- there is currently no formally agreed way of defining the current level of global warming relevant to the Paris Agreement.
Published Ash can fertilize the oceans
(via sciencedaily.com) Original source Flames roared through Santa Barbara County in late 2017. UC Santa Barbara canceled classes, and the administration recommended donning an N95, long before the COVID pandemic made the mask a household item. Smoke and ash choked the air, but the Thomas Fire's effects weren't restricted to the land and sky. Huge amounts of ash settled into the oceans, leaving researchers to wonder what effect it might have on marine life.
Published Study identifies key algae species helping soft corals survive warming oceans
(via sciencedaily.com) Original source During a two-year survey of soft corals in the Florida Keys, scientists identified three species of octocorals that have survived heat waves. While the coral animal itself may be heat tolerant, scientists concluded that the symbiotic algae inside the coral serve as a protector of sorts.
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 Antarctica's ancient ice sheets foreshadow dynamic changes in Earth's future
(via sciencedaily.com) Original source Identifying how and why Antarctica's major ice sheets behaved the way they did in the early Miocene could help inform understanding of the sheets' behavior under a warming climate. Together, the ice sheets lock a volume of water equivalent to more than 50 meters of sea level rise and influence ocean currents that affect marine food webs and regional climates. Their fate has profound consequences for life nearly everywhere on Earth.
Published Phasing out fossil fuels could save millions of lives
(via sciencedaily.com) Original source Scientists provide new evidence to motivate rapid fossil fuel phaseout. The science team determined exposure to ambient air pollution and its health impacts using an updated atmospheric composition model, a newly developed relative risk model and recent satellite-based fine particle data. They estimated all-cause and disease-specific mortality and attributed them to emission categories. They show that phasing out fossil fuels is a remarkably effective health-improving and life-saving intervention. About 5 million excess deaths per year globally could potentially be avoided.
Published What makes sustainable consumption so difficult
(via sciencedaily.com) Original source When it comes to self-discipline, psychological research traditionally focuses on individual responsibility. Some researchers believe this is too short-sighted. Self-discipline doesn't work without effective regulation.
Published Vertically farmed greens taste as good as organic ones
(via sciencedaily.com) Original source Consumer skepticism about the taste of vertically farmed greens is widespread. But a scientific taste test shows that respondents rate greens grown vertically and without soil as just as good as organic ones.
Published Decoding past climates through dripstones
(via sciencedaily.com) Original source A recent study demonstrates how dripstones can be crucial for reconstructing past climates. The new approach can provide a detailed picture of the climate around early human occupations in South Africa.
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 Inoculation against diseased fields
(via sciencedaily.com) Original source Farmland often harbors a multitude of pathogens which attack plants and reduce yields. A research team has now shown that inoculating the soil with mycorrhizal fungi can help maintain or even improve yields without the use of additional fertilizers or pesticides. In a large-scale field trial, plant yield increased by up to 40 percent.
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 Climate: Why disinformation is so persistent
(via sciencedaily.com) Original source Melting of glaciers, rising sea levels, extreme heat waves: the consequences of climate change are more visible than ever, and the scientific community has confirmed that humans are responsible. Yet studies show that a third of the population still doubts or disputes these facts. The cause is disinformation spread by certain vested interests. To try and prevent this phenomenon, a team has developed and tested six psychological interventions on nearly 7,000 participants from twelve countries. The research highlights the extremely persuasive nature of disinformation and the need to strengthen our efforts to combat it.
