Published Scientists find oceans of water on Mars: It's just too deep to tap
(via sciencedaily.com) Original source Quakes and meteor impacts on Mars generate seismic waves that can help map the interior. A new study analyzed seismic waves detected by the Insight lander and concludes that 11-20 kilometers beneath the surface, a zone of pores and fractures is filled with liquid water -- more than was thought to fill Mars' surface oceans before they disappeared 3 billion years ago. Though too deep to drill, the reservoir is a possible refuge for life.
Published Forest restoration can boost people, nature and climate simultaneously
(via sciencedaily.com) Original source Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
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 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 Millions of years for plants to recover from global warming
(via sciencedaily.com) Original source Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
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 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 International Space Station crew carries out archeological survey in space
(via sciencedaily.com) Original source An archaeological strategy adapted for space used daily photos to reveal how astronauts actually use areas aboard the International Space Station -- and how this differs from intended uses.
Published Findings from first archaeology project in space
(via sciencedaily.com) Original source The first-ever archeological survey in space has provided new insights into how astronauts use and adapt their living space on the International Space Station, which could influence the design of new space stations after the ISS is decommissioned.
Published Scientists lay out revolutionary method to warm Mars
(via sciencedaily.com) Original source Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment.
Published Monitoring of nature reserves via social media and deep learning
(via sciencedaily.com) Original source Researchers have created a deep learning method to analyze social media images taken within protected green spaces to gain insights on human activity distribution as a way to monitor the ecological impacts of these activities.
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 New report on Great Barrier Reef shows coral cover increases before onset of serious bleaching, cyclones
(via sciencedaily.com) Original source Coral cover has increased in all three regions on the Great Barrier Reef and is at regional highs in two of the three regions, according to a new report. But the results come with a note of caution.
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 Groundwater reserves in southwestern Europe more stable overall than previously thought
(via sciencedaily.com) Original source Groundwater is a vital resource, sustaining plants and ecosystems, ensuring agricultural production and serving as a core component of drinking water supplies. However, climate change and anthropogenic pressures can threaten groundwater availability, especially in southwestern Europe. This threat was evaluated by a research team using multidecadal data from more than 12,000 groundwater wells in Portugal, Spain, France, and Italy. The surprising finding: Groundwater levels are not declining everywhere as widely believed, but primarily in semi-arid regions with intensive agriculture and frequent droughts. Declines are also observed in temperate regions associated with large urban areas. The authors conclude that, with suitable management practices, groundwater can be utilized sustainably.
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 Astronomers uncover risks to planets that could host life
(via sciencedaily.com) Original source A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.
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.
Published Seismic detectors measure soil moisture using traffic noise
(via sciencedaily.com) Original source Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
