Published Taking a 'one in a million' shot to tackle dopamine-linked brain disorders
(via sciencedaily.com) Original source With the help of a tiny, transparent worm called Caenorhabditis elegans, researchers have identified novel players in dopamine signaling by taking advantage of a powerful platform generated via the Million Mutation Project (MMP) for the rapid identification of mutant genes based on their functional impact. They can seek insights from simpler organisms whose genes bear striking similarity to those found in humans and where opportunities for genetic insights to disease can be pursued more efficiently and inexpensively.
Published Just say 'climate change' -- not 'climate emergency'
(via sciencedaily.com) Original source The familiar terms 'climate change' and 'global warming' are more likely to resonate with people than other commonly used phrases.
Published Long-distance relationship revealed in the seemingly random behavior of bowhead whales
(via sciencedaily.com) Original source Applying chaos theory to the movement of iconic arctic whales uncovered a 24-hour diving cycle and a long-range (~100 km) synchronization.
Published Researchers find unexpectedly large methane source in overlooked landscape
(via sciencedaily.com) Original source Researchers reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. The research was sparked when a potent greenhouse gas began ballooning under lawns in Fairbanks.
Published Greenland mega-tsunami led to week-long oscillating fjord wave
(via sciencedaily.com) Original source In September 2023, a megatsunami in remote eastern Greenland sent seismic waves around the world, piquing the interest of the global research community. The event created a week-long oscillating wave in Dickson Fjord, according to a new report in The Seismic Record.
Published Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history
(via sciencedaily.com) Original source Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.
Published Detecting climate change using aerosols
(via sciencedaily.com) Original source Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
Published Mix of factors prompts owl monkeys to leave their parents
(via sciencedaily.com) Original source There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.
Published Alaskan land eroding faster due to climate change
(via sciencedaily.com) Original source A new study shows that frozen land in Alaska is eroding faster than it can be replaced due to climate change.
Published Sichuan Province earthquake offers lessons for landslide prediction from GNSS observations
(via sciencedaily.com) Original source Using data collected from a 2022 magnitude 6.8 earthquake in Luding County in China's Sichuan Province, researchers tested whether Global Navigation Satellite System (GNSS) observations could be used for rapid prediction of earthquake-triggered landslides.
Published Lemurs use long-term memory, smell, and social cues to find food
(via sciencedaily.com) Original source How do foraging animals find their food? A new study shows that lemurs use smell, social cues, and long-term memory to locate hidden fruit -- a combination of factors that may have deep evolutionary roots.
Published Study on planet-warming contrails 'a spanner in the works' for aviation industry
(via sciencedaily.com) Original source Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found.
Published South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows
(via sciencedaily.com) Original source Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.
Published Scientists uncover hidden forces causing continents to rise
(via sciencedaily.com) Original source Scientists have answered one of the most puzzling questions in plate tectonics: how and why 'stable' parts of continents gradually rise to form some of the planet's greatest topographic features.
Published Living with a killer: How an unlikely mantis shrimp-clam association violates a biological principle
(via sciencedaily.com) Original source When clams gamble on living with a killer, sometimes their luck may run out, according to a new study.
Published Researchers find gene which determines marsupial fur color
(via sciencedaily.com) Original source Fur is a defining characteristic of mammals, coming in a wide variety of colors and patterns -- thanks to a world-first study, we now know which genes make a marsupial's coat black or grey.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description
(via sciencedaily.com) Original source A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.
Published A new way of thinking about the economy could help protect the Amazon, and help its people thrive
(via sciencedaily.com) Original source To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.
Published Antarctic-wide survey of plant life to aid conservation efforts
(via sciencedaily.com) Original source The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe
(via sciencedaily.com) Original source Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
