Published New study provides enhanced understanding of tropical atmospheric waves
(via sciencedaily.com) Original source Findings has critical implications for predicting extreme weather events such as hurricanes and heavy rainfall.
Published A new species of extinct crocodile relative rewrites life on the Triassic coastline
(via sciencedaily.com) Original source The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.
Published Planted mangroves' ability to store carbon
(via sciencedaily.com) Original source Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published Research reveals the most complete dinosaur discovered in the UK in a century
(via sciencedaily.com) Original source The most complete dinosaur discovered in the UK in the last 100 years, with a pubic hip bone the size of a 'dinner plate', has been described in a new article.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com) Original source A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published Ancient large kangaroo moved mainly on four legs, according to new research
(via sciencedaily.com) Original source A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Life underground suited newly discovered dinosaur fine
(via sciencedaily.com) Original source A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.
Published Engine wear risk as planes swallow more dust waiting to land
(via sciencedaily.com) Original source Planes flying into one of the world's busiest airports are ingesting around 10kg of dust per 1,000 flights.
Published Exploring the radiative effects of precipitation on Arctic amplification and energy budget
(via sciencedaily.com) Original source While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.
Published How dust pollution from shrinking Great Salt Lake affects communities disproportionately
(via sciencedaily.com) Original source Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.
Published Early-onset El Niño means warmer winters in East Asia, and vice versa
(via sciencedaily.com) Original source Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.
Published Giant salamander-like creature was a top predator in the ice age before the dinosaurs
(via sciencedaily.com) Original source Meet Gaiasia jennyae, the swamp creature with a toilet seat-shaped head. It lived 40 million years before the first dinosaurs, and it was the top predator in its ecosystem.
Published Study explores what motivates people to watch footage of disasters and extreme weather
(via sciencedaily.com) Original source The release in July 2024 of the blockbuster film Twisters (centred around a social-media celebrity storm-chaser) demonstrates an ongoing public fascination in hazards and extreme weather. The arrival of camera and streaming technologies have made it easier to collect and share such footage in recent years, resulting in often dramatic footage being live-streamed on platforms such as YouTube, TikTok and Discord. Now, a new study has analyzed what might be motivating people to watch these streams -- in some instances for up to 12 hours at a time.
Published Organic material from Mars reveals the likely origin of life's building blocks
(via sciencedaily.com) Original source Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.
Published Dampening the 'seeds' of hurricanes
(via sciencedaily.com) Original source Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard
(via sciencedaily.com) Original source Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.
Published Antarctic ice shelves hold twice as much meltwater as previously thought
(via sciencedaily.com) Original source Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
